What are my options?

If your vehicle doesn't meet the emissions standards, there are a number of things you can do. Some options can take up to 3 months to complete.

Fit a filter

Fitting an approved filter to your exhaust could reduce your vehicle's emissions enough to meet the Low Emission Zone (LEZ) emissions standards.

If you do choose this option, be aware that ordering the filter, and getting it fitted and certified takes at least three months, so you need to act as early as possible and pay a daily charge if driving within the zone in the meantime.

Step 1 - Choose and order a filter

It's important to fit an approved filter, as this is the only way to get the certificate to prove that your vehicle meets the LEZ emissions standards. 

Approved suppliers and their contact details can be found on the following document:

Approved equipment can be found on the following documents:

Accredited equipment manufacturers can advise you on approved filters for your particular vehicle. We recommend you contact several filter manufacturers and get a minimum of three quotes.

When requesting a filter quotation it's important that you provide (via email or phone):

  • Vehicle make
  • Vehicle model
  • Body type/style (eg. motor home/caravan, light 4x4 utility, van)
  • Drive cycle/vehicle use (eg. urban/inner city, suburban, motorway/long distance) and percentage of time spent in each type of driving
  • Gross vehicle weight (tonnes or kg)
  • Year of manufacture
  • Engine size/displacement (litres)
  • Engine power (bhp/kW)

Approximate cost of buying and fitting a filter

  • The cost of buying and fitting abatement equipment will vary depending on the age, type and usage patterns of your vehicle.
  • Buying a filter will cost between £1,800 and £3,500 for most vans, minibuses and other specialist vehicles and between £3,500 and £7,000 for HGVs, buses and coaches.
  • Fitting costs are often included in the purchase price, and are generally between £200 and £500 for vans, minibuses and other specialist vehicles and between £300 and £500 for HGVs, buses and coaches.
  • For large vehicles or those which have been specially modified, costs may be higher. It may prove cheaper to upgrade to a newer model which meets the standards, rather than retrofit an older vehicle.

Maintenance costs

  • Most filters will need to be serviced once a year, depending on how many miles are travelled.
  • Some filters can be self-serviced by the vehicle operator, but most require a full service by a suitably trained mechanic. This will cost around £100-£200 for vans, minibuses and other specialist vehicles, and around £150-350 for HGVs, buses and coaches.

We recommend that you seek a range of quotes before making a purchase.

We are not responsible for suppliers not responding or the quotation received.

Step 2 - Get it fitted

The supplier of your filter should be able to recommend an approved fitter, who will fit the filter into your exhaust system (often replacing the exhaust silencer).

Make sure you keep all the documentation for the engine and filter, as you'll need to provide this to the Vehicle and Operator Services Agency (VOSA) to get a certificate for your filter.

VOSA are the government agency that carries out annual tests on all lorries, buses and coaches, and licences MOT garages. It also tests filters and issues all certificates showing that vehicles meet the LEZ standards.

Step 3 - Get it certified

Once your filter has been fitted, it'll need to be tested so you can get your Reduced Pollution Certificate (RPC) or Low Emission Certificate (LEC) to prove your vehicle meets the LEZ emissions standards. You can get a LEC for all types of vehicle, but RPCs are only issued to certain lorries, buses and coaches.

You can either have your filter tested by an Authorised Examiner (AE), or at a VOSA test station:

Option 1: Book and take a test with VOSA

Each VOSA test costs £32. To find your nearest centre and book your test, call 0300 123 9000.

VOSA will examine your vehicle to confirm that the filter fitted is approved, and will carry out a smoke test to confirm that it's fitted and functioning correctly (the smoke test doesn't measure the particulate matter emissions of your vehicle). Once the test is successfully completed, VOSA will issue either a LEC or RPC and submit this to TfL automatically.

It may take up to 10 days for TfL's database to be updated, so in the meantime, you'll need to pay the daily charge if you're driving in the LEZ.

Visit the VOSA website

Option 2: Take a test on site with an Authorised Examiner

You may find that the fitter of your filter is a VOSA Authorised Examiner (AE), which means they will be able to test your vehicle for you (and you won't need to book a separate test with VOSA). A fee of £32 will be charged for the test. If not, your filter supplier may be able to recommend a mobile AE who can carry out the test for you at your premises.

Once the test is successfully completed, the AE will submit documentation to VOSA, which will conduct a quality check on the documentation received.

If everything is in order, VOSA will issue either a LEC or RPC to the vehicle owner by post and will notify TfL that the certificate has been issued.

It may take up to 10 days for TfL's database to be updated, so in the meantime, you'll need to pay the daily charge if you're driving within the LEZ.

Remember to re-test every year

RPCs and LECs are normally valid for 12 months, after which you'll need to get your vehicle re-tested, or pay the daily charge if you're driving within the LEZ.

If you have a lorry, bus or coach, your first RPC or LEC will be valid until your next annual vehicle inspection at VOSA to allow you to schedule the re-test at the same time.

If you have a larger van or minibus you will need to get your vehicle re-tested at a VOSA test centre or at any one of the participating non-VOSA LEC testing sites (PDF 12KB). Please contact the site directly. This test is separate to your normal annual MOT. Please note that most AEs can only test filters the year they are fitted.

When presenting your vehicle at a VOSA test station or to an AE you must produce the previous original LEC issued to the vehicle.

Please check the current fees for a LEC test by VOSA and for certificates issued following an examination by an AE. Any additional fees incurred for tests carried out at an approved AE site should be discussed with the approved AE directly.

It is very important to:

  • Follow the filter manufacturer's maintenance schedule so that the filter doesn't block
  • Heed any warning lights or loss of vehicle performance and contact the filter installer if this occurs. It may mean that there is a build-up of soot in the filter that has not burned off. The trapped soot has a similar chemical composition to coal and needs to burn off at high temperatures. If the filter becomes overly laden with soot it can lead to increased back pressure, which can cause the trapped soot to combust and release heat. This can cause the filter to fail rapidly and means the vehicle would no longer pass the annual test at VOSA


Case studies

We've developed some case studies to show how vehicles can meet the requirements of the LEZ scheme.

Lorries, buses coaches & heavy specialist vehicles

Larger vans, minibuses & specialist diesel vehicles

Replace a vehicle

Newer vehicles have lower emissions, so you may choose to upgrade to a new (or newer) vehicle model that meets the Low Emission Zone (LEZ) emissions standards or an electric vehicle. Find out more about electric vehicles at Source London.

Second-hand vehicles

For some larger van owners it may be cheaper to purchase a second-hand vehicle that meets the Low Emission Zone standards.

Second-hand vehicles can be purchased at vehicle dealerships and online, such as Autotrader, Exchange and Mart and ebay. Auction houses, such as Auctioneers and Manheim, can be used to provide guidance on average prices. Make sure that the vehicle you purchase meets the LEZ standards.

Please note that we are not responsible for the content of any external websites.

Leasing a vehicle

If you're planning to drive in the LEZ for a short period of time only, you may wish to consider hiring or leasing a vehicle that meets the required emissions standards. Please check the BVRLA website to find a rental company near you. It's important to check that you are hiring a vehicle that meets the LEZ standards or you may be issued with a Penalty Charge Notice.

Charities, voluntary or community groups can also source transport through their local community transport project. For more information visit the CTA website.

See which vehicle types are affected

A number of major vehicle manufacturers have put together bespoke offers on new models to help owners of larger vans, minibuses and lorries affected by the LEZ meet the required emissions standards.

Reorganise your fleet

If you operate a fleet of vehicles, you could reorganise it so that only vehicles meeting the emissions standards are driven within the Low Emission Zone (LEZ).

View the LEZ map

Convert to gas

You can choose to convert your vehicle to run on pure gas with a spark ignition, using an approved conversion.

If your vehicle is registered in Great Britain, you'll need to register the conversion with the DVLA and obtain a certificate from the Vehicle and Operator Services Agency (VOSA)

Please be aware that vehicles converted to run on bio-diesel don't meet the required emissions standards.

Pay the daily charge

We would prefer that your vehicle meets the Low Emission Zone (LEZ) standards. However, if you're not able to take the measures needed, then you can drive within the zone by paying a daily charge
