The Department for Environment, Food and Rural Affairs (Defra) has announced amendments to the Heather and Grass etc Burning (England) Regulations 2021, SI 2021/158, following its March 2025 consultation. The changes extend the ban on burning of deep peat to cover a larger area of upland peat and redefine deep peat from 40cm to 30cm depth. A refined licencing system will also be introduced, permitting prescribed burning in exceptional circumstances such as wildfire risk reduction. Once implemented, these changes will increase the total area of deep peat protected from 246,156 hectares to over 676,000 hectares. As a result, burning will be prohibited on all upland blanket bog habitats unless a licence is granted by the Secretary of State. The amendments, which take effect from 30 September 2025, aim to protect peatlands, improve air quality and reduce flood risk. Defra will also publish the Heather and Grass Management Code in autumn 2025.
