UK Ready to Burn Certification Explained for Log Burner Owners
The UK government has introduced strict air quality regulations over recent years to curb particulate emissions from domestic burning. Central to this legal update is the official "Ready to Burn" scheme, administered under Defra guidance. Choosing certified compliance timber like premium kiln dry firewood ensures your fuel meets modern environmental regulations. In this guide, we break down what the Ready to Burn scheme means for homeowners, how it is enforced, and how to verify your fuel supplies.
What is the Ready to Burn Scheme?
The Air Quality (Domestic Solid Fuels Standards) (England) Regulations 2020 officially restricted the sale of wet wood in smaller volumes. Under these legal rules, all firewood sold in volumes under 2 cubic meters must be certified to have a moisture content of less than 20%.
The Ready to Burn mark reassures consumers that the timber they purchase is ready for immediate burn in wood burners and open fires without needing extra drying time at home. Burning low-moisture logs cuts down fine particulate matter (PM2.5) emissions, making air cleaner across local communities.
Legal Requirements for Fuel Suppliers and Buyers
The statutory guidelines set clear standards across the wood fuel supply chain in England and Wales:
- Volume Limits: Wood sold in units under 2 cubic meters must be fully certified as having under 20% moisture.
- Official Logo Display: Compliant packaging must feature the official Ready to Burn logo alongside the producer's unique registration number and name.
- Bulk Exemption Rules: Deliveries over 2 cubic meters must be accompanied by explicit instructions detailing how the customer must season the timber down below 20% before burning.
| Compliance Element | Certified Ready to Burn Wood | Non-Certified / Wet Wood |
|---|---|---|
| Moisture Ceiling | Strictly under 20% | Frequently exceeds 25% - 40% |
| Legal Status (< 2m³) | 100% Legal to sell in UK | Banned from retail sale in small units |
| Particulate Emissions | Reduced by up to 80% vs wet wood | High smoke output & fine particulates |
| Traceability | Unique Woodsure Producer ID on bag | Unregistered / No origin tracking |
Environmental Benefits of Burning Low-Moisture Logs
The primary driver behind domestic fuel regulations is reducing airborne pollution. When timber with high moisture levels burns, it smolders at low temperatures, releasing unburnt carbon particulates directly into the local environment. Fine particulate matter (PM2.5) can lower outdoor air quality and accumulate inside homes with poorly vented stoves.
By switching to low-moisture timber, stove owners cut particulate emissions by up to 80% compared to burning wet unseasoned logs. High operational temperatures destroy organic compounds before they leave the glass combustion chamber, creating clean heat with minimal visible smoke.

Ready to Burn Compliance Checklist
Follow this checklist to confirm your home fuel storage complies with UK domestic burning laws:
- [ ] Check that firewood bags display the official Ready to Burn logo.
- [ ] Verify that a unique 4-digit Woodsure supplier registration number is printed on the label.
- [ ] Store timber in covered, ventilated spaces to maintain its low moisture content.
- [ ] Avoid buying uncertified wet firewood in small bags from unregulated roadside sellers.
- [ ] Test your timber with a calibrated moisture meter before loading it into your burner.
Conclusion and Recommendations
The Ready to Burn legislation isn't just a legal hurdle—it is designed to protect your health, your stove, and the environment. By purchasing certified timber with guaranteed low moisture levels, you ensure maximum heat output while staying compliant with Defra guidelines. Selecting certified dry wood safeguards your flue investment and keeps your home warm and efficient all winter long.
