Get financial support to replace or adapt your vehicle

If you regularly have to pay to drive in Bath's Clean Air Zone, our financial assistance scheme can provide grants and interest-free finance to help you replace your vehicle with a cleaner compliant one, or adapt (retrofit or repower) your vehicle so that it meets the required emission standards.

Benefits of the scheme

  • For many businesses, upgrading to a compliant vehicle could be a cost-effective alternative to paying the charge over the longer term
  • Cleaner engines help to reduce harmful emissions in the city
  • If you are approved for a grant and/or interest-free finance, you can apply for an exemption on your existing vehicle while your replacement vehicle is on order
  • If you are deemed eligible for funding but you fail the necessary financial checks you can apply for an exemption on any Euro 4 or Euro 5 diesel vehicle for up to two years, and re-apply to the scheme when your finances recover


To be eligible for the scheme, you must:

  • have at least one chargeable, non-compliant vehicle that travels an average of two or more times a week in Bath’s Clean Air Zone, over a minimum 60 day period
  • have been living at, or trading from your current address since April 2020
  • have owned the vehicle you want to replace since April 2020

Check whether your vehicle will be charged in the zone

Existing non-compliant vehicles must:

  • Be roadworthy
  • Have a valid MOT certificate
  • Not be nationally or permanently exempt from charges

Priority will be given to individuals, charities, sole traders, and small businesses located in B&NES and neighbouring areas, or with premises in the zone. We will also prioritise businesses that cannot redistribute fleet to be compliant in the zone.

WarningFunds cannot be applied retrospectively, so please do not buy a new vehicle before we’ve checked your eligibility and explained the process

What you can do with the funds

If you are eligible, you can use the funds to reduce the cost of:

  • Replacing an existing non-compliant vehicle with a new, or second-hand, vehicle of a similar make or model that meets the required emissions standards
  • Adapting (retrofitting or repowering) existing or replacement non-compliant vehicles to meet CVRAS standards

Your replacement vehicle can be a compliant diesel, petrol or a used electric or hybrid vehicle. In exceptional circumstances, we can provide funds to replace a non-compliant vehicle with a different make or model, if this brings an additional air quality benefit, or protects vital services.

The scheme cannot be used for adding vehicles to your fleet.

Selling or trading-in your existing vehicle

If you are replacing your vehicle, you must sell or trade-in your existing non-compliant vehicle on or before the day you receive the new one. You can clarify this process later in your application with one of our financial providers. 

Discount for new electric or hybrid vehicles

You can get a discount on the price of a brand new low-emission vehicle through a grant the government is giving directly to vehicle dealerships and manufacturers. Visit GOV.UK to find out how it works and which vehicles are eligible.

How much you could get

In addition to interest-free finance, you could receive a grant of up to 35% of the net upgrade costs (the base price of the new vehicle before any additional cost options less VAT, the trade-in value of your old vehicle and any supplier or manufacturer discounts), significantly reducing the final cost of either replacing or adapting your existing vehicle.

Grants are capped for each vehicle type, as follows:

  • Taxis, PHVs and vans: up to £4,500
  • HGVs: up to £20,000
  • Buses and coaches: up to £35,000

How the scheme works

Register your interest in this scheme using our online form (below).

Tracking device

Before we can put you in touch with our finance providers, we need to establish that you drive your vehicle(s) at least two days a week in Bath’s Clean Air Zone.

To record your vehicles movements, we will fit a telematic (tracking) device in your vehicle for two months. This must be left in your vehicle all the time, until we ask you to return it. A report of your vehicle’s trips into Bath's Clean Air Zone will then be produced.

If the data confirms that your vehicle is driving a minimum of twice a week in the zone, and you meet the additional criteria listed in the eligibility section above, your application will be passed to one of our finance providers (funds for this scheme are administered by a number of approved finance providers on our behalf).

Exempt from charges

Your vehicle will be exempt from charges:

  • While your tracking device is in place (provided the tracker is fitted before 19 July 2021)
  • For up to 30 days from the end of your tracking period while we process your data and you begin your finance application (provided the tracker was fitted before 19 July 2021)
  • If you are approved for a grant and/or interest-free finance, but you're waiting for your replacement or adapted vehicle to be ready (you can apply for a temporary exemption for your existing vehicle until you expect your replacement or adapted vehicle to be ready, or for up to two years from the zone’s launch, whichever is sooner)

Credit checks

All applications for funds will be subject to credit checks.

The maximum repayment period for the interest-free finance will be 60 months, but this can be extended to 84 months for some specialist vehicles, including buses and coaches.

WarningIf you pass the eligibility assessment but fail the financial checks, you can apply to exempt any Euro 4 or Euro 5 diesel vehicles for up to two years from the zone’s launch.

Register your interest

Funds for the scheme are forecast to be fully allocated, which includes all of the vehicles currently on our waiting list on or before 10 June 2021, and the vehicles already being assessed or approved for replacement. This is in line with our initial expectation to help replace around 1,500 vehicles.

We are seeking additional funds from central government to extend the scheme so we urge you to complete the form below if you’ve not already registered your interest.

We will contact you about the outcome of our bid for additional funds, and to explain the full terms and conditions and how to apply to the scheme. This will not affect your credit rating and there is no obligation to apply.

You will need to supply the following information on the form:

  • How many non-compliant vehicles you have
  • Whether the vehicles have telematics fitted
