Guidance

Getting fuel authorised for sale in smoke control areas

What you need to do to get your fuel authorised for use in domestic heating appliances in smoke control areas.

Many parts of the UK are smoke control areas where there are rules about the fuels and appliances allowed to be used in domestic homes.

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

Alongside the smoke control area rules, if you sell fuel in England you need to follow the rules which came into force on 1 May 2021.

Fuels that can be authorised

To be authorised for use in UK smoke control areas, 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)

You do not need to apply for authorisation if the fuel is already on the list of authorised fuels.

Unauthorised fuels can be used in some exempt appliances, for example some stoves, fireplaces and boilers.

Smokeless fuels

You do not need to apply if it is any of the following ‘smokeless’ fuels:

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

How to apply

Contact HETAS with the following details about your fuel:

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

HETAS will give you feedback about your application and what testing is needed – you may need further testing even if some has already been done.
