A Guide to the UK Ready to Burn Certification Scheme
In recent years, the UK government has updated clean air regulations for domestic heating. The Air Quality (Domestic Solid Fuels Standards) Regulations make it illegal to sell wet firewood in small domestic volumes. As a result, the "Ready to Burn" certification scheme has become an essential quality mark for British homeowners.
This initiative directly supports the goals covered in our core guide, How to Choose the Best Firewood for Your Home. In this article, we explain what the scheme means, how the regulations operate, and how it protects your health, appliances, and fuel budget.
What Is the Ready to Burn Scheme?
The Ready to Burn scheme is an official government-backed certification programme run by Woodsure, the UK's leading wood fuel testing organisation. The scheme ensures that solid fuels sold for domestic fireplaces meet strict moisture standards.
Under the regulations, any wood sold in volumes under two cubic metres must be independently tested and certified to have a moisture content of 20% or less. Retail bags and delivery crates must display the official certification logo along with the producer's unique registration number.

Why the UK Government Introduced the Ban on Wet Wood
Burning wet wood is a major source of dangerous fine particulate pollution, known as PM2.5. These tiny soot particles can enter human lungs and pass directly into the bloodstream, worsening respiratory and cardiovascular health conditions.
Wet wood burns at low temperatures because so much energy is spent evaporating water. This incomplete combustion produces heavy plumes of grey smoke packed with unburnt chemicals. By contrast, certified dry wood burns cleanly at high temperatures, turning smoke and volatile compounds into heat before they exit the flue.

Understanding Smoke Control Areas
Many towns, suburban areas, and cities across England, Wales, and Scotland are designated Smoke Control Areas under the Clean Air Act. In these zones, releasing smoke from a domestic chimney is an offence that can lead to fines of up to £1,000.
To burn firewood inside a Smoke Control Area legally, you must meet two core requirements:
- A DEFRA-exempt stove: Your appliance must be approved by the Department for Environment, Food and Rural Affairs for clean burning.
- Authorised dry fuel: You must burn approved fuels or certified dry wood displaying the official Ready to Burn logo.
To ensure your fireplace follows all local council requirements, read our guide to UK Smoke Control Rules for Open Fires and Wood Stoves.
Can You Still Buy Unseasoned Wood in Bulk?
The law does not completely ban the sale of unseasoned green wood. Commercial forestry yards can still sell unseasoned timber in volumes larger than two cubic metres. However, the supplier must provide written advice explaining how to season the logs down below 20% moisture before burning.
Buying unseasoned wood in bulk can save money if you have a large garden and the patience to season logs for two years. However, for immediate burning in suburban log burners, certified dry timber is the only legal, safe choice.
Connecting Quality Certification with Timber Selection
The Ready to Burn standard guarantees moisture control, but it does not specify wood species. You can buy certified dry softwood or certified dry hardwood. To choose between these two timber types, read our comparison on Hardwood or Softwood: Which Is Better for Your Log Burner?.
Most certified firewood sold in UK supermarkets, fuel merchants, and garden centres has undergone industrial heating. To discover how kilns dry timber to certified standards, read What Is Kiln Dried Firewood and Is It Worth It?.
Summary Checklist for UK Homeowners
| Action | What to Look For | Why It Matters |
|---|---|---|
| Check the bag | Official Ready to Burn logo with supplier number | Guarantees timber has less than 20% moisture |
| Check your area | Local council Smoke Control Area status | Prevents council fines and excess smoke output |
| Verify your stove | DEFRA exemption or Ecodesign compliant badge | Confirms clean air compliance for your chimney |
| Inspect moisture | Digital pin meter reading below 20% | Ensures maximum heat and zero chimney creosote |
The Benefits of Supporting the Standard
The Ready to Burn scheme makes shopping for firewood easy and straightforward. By looking for the Woodsure certification logo, you protect your stove from corrosive soot, keep chimney maintenance low, avoid legal fines, and help protect the air quality in your local neighbourhood.
