If you’re a fuel manufacturer, importer or distributor, you can apply to get your fuel authorised so your customers can use it in smoke control areas.

When you don’t need to apply

You don’t need to apply if the fuel is already on the list of authorised fuels or is any of the following ‘smokeless’ fuels:

  • anthracite
  • semi-anthracite
  • gas
  • low volatile steam coal

Unauthorised fuels can be used in some ‘exempt appliances’, eg some stoves, fireplaces and boilers.

Fuels that can be authorised

To be authorised, fuel must:

  • have an average smoke emission of less than 5 grams per hour when tested to the standard (BS3841)
  • contain less than 2% sulphur (by dry weight with a 95% confidence limit)

How to apply

Contact Ricardo Energy & Environment with the following details about your fuel:

  • what it’s made of
  • how it’s manufactured
  • any testing that’s already been carried out

Ricardo Energy & Environment will give you feedback about your application and what testing is needed - you may need further testing even if some has already been done.

After you apply

You’ll be given an estimated timescale - this will vary depending on when you apply.

If your fuel meets the requirements it will be authorised and added to the authorised fuels list.

How much it costs

It costs £1,000 (excluding VAT) to get a fuel authorised.

You’ll also have to arrange and pay for any testing that’s required.
