HETAS is a fuel quality scheme operated by Woodsure. An accreditation guarantees that domestic solid woodfuels are good quality, are safe, and offer efficient combustion. HETAS also test for particle size, impurities, and moisture content in order to offer assurance on reliability and performance.

The Woodsure certification scheme and its logo identify woodfuels that consumers can trust, avoiding poor quality fuels that waste energy, are bad for the environment, and ultimately cost more for the consumer.

Customers purchasing from a Woodsure certified brand can be confident that they are buying from a responsible and conscientious producer.
