Fuel Schemes

To ensure satisfactory performance of domestic solid fuel and wood-burning appliances, it is important to use fuels that are of a suitable type and size. Good quality fuels are essential for safe and efficient combustion as poor quality fuels waste energy and ultimately cost more for the consumer.  All HETAS accredited fuels have undergone certification in accordance with the relevant standard, providing consumer confidence that the fuels being burnt are both safe and efficient for the type of appliance they have.

Solid Mineral Fuel (HETAS Approved)

All solid mineral fuels listed have been tested and approved by HETAS on behalf of the fuel producer. The testing and approval combined with a quality assurance scheme enables the fuel to carry the HETAS Approved Solid Fuel logo which the consumer should look for.
