London congestion charge
Encyclopedia
The London congestion charge is a fee charged for some categories of motor vehicle to travel at certain times within the Congestion Charge Zone (CCZ), a traffic area in London. The charge aims to reduce congestion, and raise investment funds for London's transport system. The zone was introduced in central London

 on 17 February 2003, and extended into parts of west London on 19 February 2007. Though not the first scheme of its kind in the United Kingdom, it was the largest when introduced, and it remains one of the largest in the world. Several cities around the world have referenced London's congestion charge when considering their own schemes.

The standard charge is £10 for each day, for each non-exempt vehicle that travels within the zone between 07:00 and 18:00 (Monday-Friday only); a penalty of between £60 and £180 is levied for non-payment. On 4 January 2011 several changes were implemented based on the public consultation conducted in 2008, which included the removal of the Western Extension, a charge increase from £8 to £10, and the introduction of an automated payment system.

), though the zone was primarily thought of (and zoned) as commercial rather than residential. There was little heavy industry within the zone. Signs were erected and symbols painted on the road to help drivers recognise the congestion charge area.

Payment

While drivers of private vehicles can pay the daily charge either the day before, on the day or on the following day, whether they are seen to enter the zone or not, the same does not apply to fleets of business vehicles. Businesses with a minimum of ten or more vehicles can register with TfL, and will be charged £7 per vehicle per day for vehicles in the fleet detected by the cameras. In May 2005, businessman Miguel Camacho set up fivepounds.co.uk (referring to the then-current pricing), whose sole function was to sign up private drivers to their "fleet", thus offering the convenience of not having to pay the charge pro-actively, avoiding fines in the case of a forgotten journey and also potentially getting a "free journey" if undetected by the cameras. TfL, which obtains nearly half of its net revenue from fines, moved quickly to quash the loophole, by demanding that fleet operators provide the registration document

 for each vehicle in their fleet. Fivepounds went out of business on 26 February 2006.

Several changes went into effect beginning 4 January 2011, including the introduction of Congestion Charging Auto Pay (CC Auto Pay), which is an automated payment system that automatically records the number of charging days a vehicle travels within the charging zone each month and takes the charge from a registered debit or credit card on a monthly basis. Any user can nominate up to five vehicles for each CC Auto Pay account and drivers of these vehicles pay a reduced £9 daily charge. Those signing up to CC Auto Pay pay an annual £10 registration charge per vehicle. The congestion charge was increased to £10 if paid in advance or on the day of travel; to £12 if paid by midnight the charging day after travel; and to £9 if registered for Congestion Charging Auto Pay.

Residents of the zone are eligible for a 90% discount if they pay the charge for a week or more at once, although there are administration charges – presently a minimum of £10 – for claiming the discount. Some residents who live close to the West London extension are also entitled to the resident's discount.

Drivers of foreign-registered vehicles are not exempt from the charge but the current lack of an international legal framework for the assessment and collection of traffic fines makes enforcement and recovery difficult. In 2005, The Guardian

. TfL argues that the charge is a toll, not a tax. In April 2006, after not paying it since its introduction in February 2003, the embassy of the United Arab Emirates decided that its diplomats would now pay the charge. As of May 2011, £51m was claimed to be owed to Transport for London by at least ten foreign embassies.

TfL can and does suspend the congestion charge either in a small local area to cope with incidents and if directed to do so by a police officer. The congestion charge was suspended on 7 and 8 July 2005 in response to the terrorist attacks on London Transport
7 July 2005 London bombings
The 7 July 2005 London bombings were a series of co-ordinated suicide attacks in the United Kingdom, targeting civilians using London's public transport system during the morning rush hour....

. The congestion charge was also suspended on 2 February 2009, in response to an extreme weather event (heavy snow fall) in the London area.

Penalties and avoidance

Failure to pay results in a fine of £120, reduced to £60 if paid within 14 days, but increases to £180 if unpaid after 28 days. Although avoidance has become more sophisticated, compliance with the scheme and terms of payment has improved over the last few years, as is evidenced by the income from penalties dropping by approximately a quarter between 2005 and 2007. However, even after charges were increased, enforcement charges still make up a significant proportion of the net revenues. Several newspapers have reported that copied number plates
British car number plates
Vehicle registration plates are the mandatory number plates used to display the registration mark of a vehicle, and have existed in the United Kingdom since 1904...

 are being used to avoid the congestion charge, resulting in vehicle owners receiving penalty notices for failure to pay when their vehicles have not been inside the zone. TfL has stated it is keeping a database of these numbers and that they will trigger an alert. The 2008 annual report on the operation of the scheme shows that around 26% of penalties go unpaid, because the notice is cancelled on appeal or the amount cannot be recovered, for example if the registered keeper of the vehicle cannot be traced, is deceased, or bankrupt.

In 2007 a green motoring website alleged to TfL that owners of luxury cars were registering their vehicles as minicabs in order to qualify for exemption from the charge. Registering a vehicle as a minicab costs £82 plus £27 per year licence fee, much less than the congestion charge. TfL responded that it carried out regular checks to confirm that cars were being used for the purposes they were registered for, and that they had not discovered any such cases.

Entry authorisation and penalties cannot be issued to non-UK numberplates, and detection cameras may also be unable to read them, meaning that foreign plates are sometimes used to avoid the charge, although cars with foreign plates may only be used in the UK for up to six months before being considered to have been officially imported and thenceforth required to have UK plates.

 had proposed in his manifesto to introduce a £5 charge for vehicles entering central London. Following his victory, the Mayor made a draft order and requested a report from TfL, which summarised the reasons for introducing the scheme. The scheme was to be introduced to reduce congestion in the centre of the capital following the Draft Transport Strategy of January 2001 which had highlighted the importance that the Mayor placed on tackling this issue. The charge was to be part of a series of measures to improve the transport system in London and was to combined with public transport improvements, increased enforcement of parking and traffic regulations. The report stated that the scheme was expected to be the most effective in reducing through traffic, reducing congestion both within and outside the zone, improving the speed of buses and the quality of life in central London. It was stated that improved traffic flows would make London more attractive to business investment. Substantial net revenues were anticipated, which were to be invested in London's transport system.

Effects

The effects of the congestion charge have been controversial. Studies have been made of its effects on congestion, traffic levels, road safety, the use of public transport, the environment, and business activity matters.

Immediate impact

On the first day 190,000 vehicles moved into or within the zone during charging hours, a decrease of around 25% on normal traffic levels, partly due to it also being the half-term school holiday. A report from the Bow Group

 stated that historically, London congestion is at its worst during the morning rush hour, and that the early days of congestion charging had little impact on that critical time, the main effect occurring after 11 am. Just over 100,000 motorists paid the charge personally, 15–20,000 were fleet vehicles paying under fleet arrangements, and it was believed around 10,000 liable motorists did not pay the due charge.

Initial suggestions that school holidays were responsible for part of the traffic drop during the first week of operation of the charge were confirmed when traffic rose again by 5% following the return to school at the beginning of the second week of the charge. Reports indicated that, over the first month or so of operation, traffic was consistently down at least 15% on pre-charge levels, with the second week seeing the reduction drop to 20%.
The AA Motoring Trust suggested that changes to the timing of traffic lights and the end of major road works had also impacted congestion.

On 23 October 2003 TfL published a report reviewing the first six months of the charge. The report's main findings were that the average number of cars and delivery vehicles entering the central zone was 60,000 fewer than the previous year. Around 50–60% of this reduction was attributed to transfers to public transport, 20–30% to journeys avoiding the zone, 15–25% switching to car share, and the remainder to reduced number of journeys, more travelling outside the hours of operation, and increased use of motorbikes and bicycles. Journey times were found to have been reduced by 14%. Variation in journey time for a particular route repeated on many occasions also decreased. The report also claimed that although the charge was responsible for about 4,000 fewer people visiting the zone daily, that the charge was responsible for only a small fraction of the 7% drop in retail sales reported.
The report also stated that around 100,000 penalty fines were issued each month, of which about 2,000 were contested.

 saw an average 25% reduction in traffic numbers.

Traffic changes

A year before the congestion zone, TfL set up automatic traffic counters and augmented them with regular classified traffic counts at key locations, in order to monitor long term trends. Their results are reviewed and reported annually.

A report by TfL in early 2007 indicated that there were 2.27 traffic delays per kilometre in the original charging zone. This compared with a figure of 2.3 before the introduction of the congestion charge. After the scheme was introduced they had measured an improvement in journey times of 0.7 minutes per km, or 30%. This improvement had decreased to 22% in 2006, and during 2006 congestion levels had increased so that the improvement, compared to the year before the scheme, was just 7%. TfL explained this as a result of changes to road priorities within the zone, delays caused by new pedestrian and road user safety schemes, and, most particularly, a doubling of road works in the latter half of 2006.
(Utilities were encouraged to complete planned road works in the year proceeding the congestion charge, so it would appear that the first year of measurement used for later comparisons would also have been affected by streetworks to some extent.)

TfL's report in June 2007 found that the level of traffic of all vehicle types entering the central Congestion Charge Zone was now consistently 16% lower in 2006 than the pre-charge levels in 2002. The conservative Bow Group
Bow Group

 noted that the main effect occurred after 11 am.

Breaking down that figure showed the number of chargeable vehicles entering the zone had reduced by 30% (primarily cars and minicabs, although vans and lorries had decreased by 13%), while there were overall increases in the numbers of taxis, buses, and especially bicycles. The daily profile of traffic flows had changed, with less traffic after 9:30 am and a peak immediately before and after the end of the charging period. The level of traffic entering the zone during the morning peak had not reduced as much as at other times.
They had noted a small but pervasive long term trend of less traffic entering the zone, expected to be a result of people changing their location and lifestyle, perhaps influenced by the charge.
Once within the charging zone car and delivery traffic remained unchanged, suggesting that the journeys made by residents and businesses within the zone were broadly unaffected. Changes to the road network over the years has made direct comparisons difficult, but TfL suspect that certain routes used heavily by taxis and buses within the zone have seen substantially increased traffic.
On some of the boundary roads traffic numbers had increased slightly but congestion and delays were largely unchanged from 2002 levels.
Year on year, counts of inbound traffic approaching the zone had also seen a distinct and significant 5–7% decline in the number of chargeable vehicles, which was unexplained.

The charge operates for under one third of the hours in a year and covers around two thirds of the central London traffic. In total 8% of traffic kilometres are affected by the scheme. TfL have extrapolated the trends in road speed in the congestion zone; they have suggested that speeds would have dropped from 17 km/h in 2003 to 11.5 km/h by 2006, had the scheme not been put in place.

Following the introduction of the Western Extension, TfL stated that traffic had fallen around 10 to 15% in the extended zone. The original zone is showing a 4% increase in congestion following expansion of the congestion charge and the introduction of extended to discounts to residents of the new zone and buffer zone.
TfL assessed the increase in charges in 2005 to have had only a slight impact overall.

Although it was suggested that the scheme should improve the speed of vehicles in the centre, the London Ambulance Service

 (LAS) anticipated increased volumes of traffic around the edge of the zone and an increase in demand within the zone, that might both adversely affect clinical outcomes.
However, since then, survival rates for LAS' witnessed cardiac arrests have tripled across Greater London. LAS attributes these improvements to equipment availability and operational processes, such as the deployment of four-wheeled and two-wheeled rapid response units that can weave through congestion more quickly.
This, and TfL's increase in the number central London traffic calming measures, would suggest that other much more significant factors have masked any congestion charge-related changes in outcome, either up or down. In addition, like some other essential services, LAS felt it necessary to divert about £¼M from their budget to pay congestion charge allowances for key staff affected by the charges during their journey to work.

According to a November 2007 newspaper report, TfL data showed that after an initial improvement, that rush-hour congestion had become worse than it was before the congestion charge was introduced. In December 2007, another article contained a similar observation, that although after the first year the results were looking good, with traffic speeds up, that at the time of writing, traffic speeds and delays were virtually back to their February 2003 levels.

Road safety

TfL have estimated that the charge appeared to have had a small impact on the number of road traffic accidents – but this was much less than the national and London trend towards fewer accidents. There were 2,598 personal injury road traffic accidents inside the zone in the year before the scheme. This fell by about 200 each year to 1,629 in 2005. TfL's statisticians have extrapolated an estimate that between 40 and 70 injuries have been avoided annually because of the charging zone, with most of the rest attributed to the changes that altered and slowed down the road network "in favour of the people-moving capacity of the network."

TfL expects that many of these road safety interventions would have occurred irrespective of the introduction of congestion charging. Cars and motorcycles have seen the biggest reduction in accidents, whereas bicyclists have seen a slight increase, which perhaps reflects their increased numbers. For comparison, the inner ring road also saw a substantial drop as accidents fell from 961 to 632, which was slightly less than the average for Greater London.

Another effect of the scheme, which relies on the recognition of vehicle number plates

 of the number plate, without first checking whether the vehicle to which the plate belongs was actually the offending vehicle, the onus being placed on the keeper to prove their innocence. Car breakers are amongst those being targeted as a source for number plates to be illegally used on other vehicles. The BBC reported in October 2005 that the AA Motoring Trust estimated that 1 car in every 250 entering the charging zone was displaying false plates. In 2006 police estimated that more than 40,000 number plate sets were stolen.

Public transport

On the launch date of the original zone, an extra 300 buses (out of a total of around 8,000) were introduced.

 patronage had been noted as a result of the introduction of the central zone charge.

Since the introduction of the western extension, TfL has made a number of bus route changes to take advantage of the presumed higher traffic speeds and the greater demand for public transport. One new route (route 452

, 46 and 430) have been extended. In addition, the frequency of buses on other routes through the zone extension has been increased.

Business

The effect of the congestion charge zone on local businesses is a contested issue. The TfL estimates that the effect on business has been overall neutral.
However the effect on business differs significantly by between stores. Some shops and businesses are reported to be heavily affected by the charge, both in terms of lost sales due to reduced traffic and increased delivery costs, as recognised by the London Chamber of Commerce.

 for the first time.

However London First's own report indicated that business was broadly supportive. Subsequently another report stated that there had been a reduction in some employment in the charging zone. TfL criticised the reports as unrepresentative and that its own statistics reported no effect on business.

A report in May 2005 stated that the number of shoppers had declined by 7% year-on-year in March, 8% in April and 11% in the first two weeks of May. TfL countered that an economic downturn, the SARS outbreak

 and threat of terrorism were likely factors. At the same time a London Chamber of Commerce report indicated that 25% of businesses were planning on relocation following the charges introduction. However an independent report six months after the charge was implemented suggested that businesses were then supporting the charge. London First commissioned the study which reported that 49% of businesses felt the scheme was working and only 16% that it was failing. The Fourth Annual Review by TfL in 2004 indicated that business activity within the charge zone had been higher in both productivity

 and that the charge had a "broadly neutral impact" on the London wide economy. The Fifth Annual Review continued to show the central congestion zone outperforming the wider London economy.

The Centre for Economics and Business Research predicted that the West London extension in February 2007 would cause 6,000 job losses. In May 2007, a survey of 150 local businesses stated they had seen an average drop in business of 25% following the introduction of the charge, which was disputed by TfL which stated that there had been "no overall effect" on business and that it had outperformed the rest of the UK in the central zone during 2006.

The pre-commencement report from TfL noted that the scheme wasn't expected to significantly affect air quality, but that offering a discount to encourage the use of greener fuels would be a positive measure.

In total, the rate of fall in CO2 has been almost 20% as of 2007. The TfL report makes it clear that only a one-off reduction of emissions could be expected from the introduction of the charge, whilst further reductions are unlikely to be as a result of the charge.

Preliminary reports also indicate the rate of decline in certain pollutants is decreasing.

A 2011 independent study published by the Health Effects Institute

The Health Effects Institute is a independent, non-profit corporation specializing in research on the health effects of air pollution. It is headquartered in Boston, Massachusetts, USA....

 (HEI), and led by a researcher from King’s College London, found that there is little evidence the congestion charge scheme has improved air quality. This research used modelling and also compared actual air pollutant measurements within the congestion charge zone with those of control sites located in Outer London. The investigators concluded that "it is difficult to identify significant air quality improvements from a specific program—especially one targeted at a small area within a large city—against the backdrop of broader regional pollutant and weather changes."

Outer London

The charge has proved controversial in the outer areas of London, where it has encouraged commuters who previously drove into central London to instead park at suburban railway or underground stations. This has been accompanied by the introduction of extra on-street parking restrictions and controlled parking zones in these areas, which affects local residents.

Income and costs

TfL's annual report for 2006–7 shows that revenues from the congestion charge were £252.4m over the financial year, representing 8.5% of TfL's annual revenues. More than half of this was spent on the cost of running the toll system, at £130.1 million. Once other charges were deducted, the congestion charge brought in an annual operating net income

 of £89.1m for TfL.
(This income compares with TfL's total revenue from bus and tube fares of £2,269.4m, or 76.6% of revenue before costs, or grants from central government of £2,390.3 million.)

By law, all surpluses raised must be reinvested into London's transport infrastructure; at the start of the scheme it was anticipated that this would be around £200 million. According to a report issued in February 2007, the initial costs of setting up the scheme were £161.7 million, with an annual operating cost of about £115m anticipated.
Total revenues over the first three and a half years had been £677.4 million, with TfL reporting a surplus over operating costs of £189.7 million.

The initial operating revenues from the congestion charge did not reach the levels that were originally expected. Within six months of the start of the scheme, the reduction in traffic had been such that TfL were predicting a £65 million revenue shortfall.

The June 2005 increase in charges by 60% only resulted in a relatively small rise in revenues, as there were fewer penalty payments.
The anticipated start up costs of the Western extension were £125 million with operating costs of £33m; expected gross revenues were expected to be £80 million resulting in net revenues of £50 million.

A few days before the scheme came into operation, he wrote in a BBC report that it had been "shambolically organised", that the public transport network had insufficient spare capacity to cater for travellers deterred from using their cars in the area by the charge. Further, he said that the scheme would affect poorer sections of society more than the rich, with the daily charge being the same for all, regardless of vehicle size.
He pledged to scrap it if he became mayor in June 2004. He had also pledged that, if elected, he would grant an amnesty to anyone with an outstanding fine for non-payment of the charge on 11 June 2004. In an interview with London's Evening Standard

's plan to introduce a £25 charge for the heavy-polluting vehicles will not go ahead.

Further proposals

After the introduction of the charge, there were a number of suggestions for its future. Soon after charging commenced, Livingstone announced that he would carry out a formal review of the charge's success or failure six months after its introduction – brought forward from one year, following the smooth start. On 25 February 2003 Livingstone stated, "I can't conceive of any circumstances in the foreseeable future where we would want to change the charge, although perhaps ten years down the line it may be necessary" referring to the amount that drivers have to pay, indicating that £5 was sufficient to bring about the reduction in traffic that he had hoped for. By November 2004, Livingstone directly contradicted his earlier stance and said in an interview with BBC London, "I have always said that during this term [his second term in office] it will go up to at least £6." By the end of the month, Livingstone changed his position again, saying in an announcement that, in fact, the rise would be to £8 for private vehicles and £7 for commercial traffic. Business groups such as London First said following the announcement that the charges were "totally unsatisfactory and unacceptable". The rise to £8 was announced formally on 1 April 2005, along with discounts for drivers buying month or year-long tickets. On 10 May 2006, in a live TV debate, Livingstone supported a rise in the charge to £10 by 2008.

Western extension

In February 2004, TfL issued a consultation document on the expansion of the zone to the west that would cover the rest (western portion) of Westminster and the Royal Borough of Kensington and Chelsea

. The extension covered around 230,000 residents, compared with the 150,000 in the original zone.

In August 2004, following Livingstone's re-election in the June 2004 mayoral election

Polling opened at 07:00 local time, and...

, the results of the consultation were published. A substantial majority of respondents did not want the extension, however Livingstone said he was going ahead and that the polls were a "charade" which did not diminish his electoral mandate. "A consultation is not a referendum" he said. Protests continued against the extension, with residents arguing that only 5% of the road space in the selected area was congested. Following on in May 2005 TfL a further consultation began with specific proposals about the extensions. These included a plan to reduce the operating hours of the charge by half-an-hour to "boost trade at London's theatres, restaurants and cinemas".

At the end of September 2005, London Mayor Ken Livingstone confirmed the western expansion of the congestion charge, which came into effect on 19 February 2007. It was expected that the extension would increase congestion in the zone by around 5% as the 60,000 residents in the new zone will be entitled to the discounts available. Several roads were also to be left charge-free between the original zone and the extension.

However, the current Mayor of London, Boris Johnson

, at the beginning of his administration, announced that he would discard plans for extending the charge zone to the suburbs, and also announced he will review the western extension implemented in 2007, based on a public consultation planned for September 2008. Having held a five-week public consultation with residents in autumn 2008, Johnson agreed to remove the western extension of the congestion charging zone by 2010. Out of 28,000 people who responded to the consultation, 67% of the respondents, including 86% of businesses, said they wanted the extended zone removed.

On 20 October 2010, TfL announced that Mayor Johnson decided to remove the Western Extension which, together with other changes to the scheme, were scheduled to take effect from 4 January 2011. However, because there is no charging due to the Christmas holidays, charging on the Western extension effectively ended on 24 December 2010.

Transponder charging

TfL ran a six month trial of "tag and beacon" (transponder) from February 2006 to replace the camera based system. This uses an electronic card affixed to the windscreen of a vehicle and can be used to produce "smart tolls" where charges can be varied dependent on time and direction of travel. This system automatically deducts the charge so that the 50,000 drivers a year who forget to pay the fine would not be penalised. TfL has suggested that this scheme could be introduced from 2009.

Blackwall Tunnel charging

Transport for London consulted on a charge for the Blackwall Tunnel

 (VED) bands would be introduced. This would reduce or eliminate the charge for Band A vehicles, and increase it to up to £25 a day for Band G vehicles, with CO2 emissions greater than 225 g/km.

Consultation on these proposals began in August 2007 and ended on 19 October 2007.

On 12 February 2008 TfL announced that on 27 October 2008 they would introduce a new charging structure for vehicles entering the congestion zone, based on potential CO2 emission rates.

The main change would be the introduction of two new fees:
  • £25 per day (with no residents' discount) for cars which, if first registered on or after 1 March 2001 are rated in Vehicle Excise Duty (VED) "Band G" (emitting above 225g/km of CO2), or if first registered before 1 March 2001 have an engine capacity of greater than 3000 cc and for pickups with two rows of seats which either are rated as emitting above 225g/km of CO2 or which have an engine capacity of greater than 3000 cc. It should be noted that in Alistair Darling's 2008 budget it was announced that VED Band G would be lowered to 151g/km of CO2. TfL had not clarified whether the £25 daily charge would be linked to the band until the point became moot as the scheme was cancelled.
  • £0 per day (a 100% discount) for cars that either are rated as emitting less than 120g/km CO2 and which meet the Euro 4 air pollution emissions standard or which are rated as emitting no more than 120g/km CO2 and which appear on the PowerShift register.


Acting director of the RAC Sheila Raingner stated that "The congestion charge was originally developed to reduce congestion. Changing this will confuse the public and reduce support and trust for future initiatives."
