If you’ve confirmed that your stove is DEFRA-approved, you’re in the best position for Cambridge’s new city-wide Smoke Control Area starting January 2026.
Not sure if your stove is DEFRA approved? Check out our article on how to identify DEFRA-approved stoves for step-by-step instructions on checking your appliance.
DEFRA approved stoves in Cambridge give you the maximum flexibility – you can continue burning both seasoned wood and approved smokeless fuels.
However, having a DEFRA-approved stove doesn’t mean you can burn anything you want. There are still important Cambridge DEFRA stove rules about fuel quality, burning techniques, and maintenance that you must follow to stay compliant and avoid penalties.
As Cambridge chimney professionals with over 40 years of experience helping residents operate their DEFRA-approved stoves efficiently, we’ll guide you through everything you need to know to stay compliant while getting the best performance from your stove.
Why DEFRA Approved Stoves Have More Freedom in Cambridge
DEFRA-approved stoves have been independently tested and certified to burn wood with very low smoke emissions. This certification is what allows them to operate in Smoke Control Areas where non-approved stoves cannot burn wood.
Key Features of DEFRA-Approved Stoves:
- Advanced combustion systems that burn fuel more completely
- Secondary combustion chambers that re-burn smoke particles
- Controlled air supply systems for optimal burning conditions
- Designed to meet strict emissions standards
Your Fuel Options in Cambridge’s Smoke Control Area:
- Properly seasoned wood (under 20% moisture content)
- All approved smokeless fuels
- Both can be used safely and legally
This flexibility means you can choose based on availability, cost, seasonal preferences, or simply what you have available – as long as you follow the quality and operating requirements across all Cambridge wards including Abbey, Arbury, Castle, Cherry Hinton, Coleridge, East Chesterton, King’s Hedges, Market, Newnham, Petersfield, Queen Edith’s, Romsey, Trumpington, and West Chesterton.
What Wood Can I Burn in My DEFRA Stove Cambridge?
Even with a DEFRA-approved stove, you cannot burn just any wood. Cambridge’s Smoke Control Area has specific requirements for wood moisture content and quality.
DEFRA Stove Wood Moisture Requirements Cambridge
Legal Requirement: Wood burned in DEFRA-approved stoves must have a moisture content of 20% or less. This isn’t just a recommendation – it’s a legal requirement for compliance in Cambridge’s Smoke Control Area.
Why Moisture Content Matters:
- Wet wood produces excessive smoke and particulates
- High moisture reduces heat output and efficiency
- Creates tar and creosote buildup in chimneys
- Contributes to air quality problems
How to Check Moisture Content:
- Use a digital wood moisture meter
- Test multiple pieces from different parts of your wood supply
- Test freshly split surfaces, not the exterior
- Take readings from both ends of logs
What Counts as “Seasoned Wood”
| Proper Seasoning Process: | Wood cut and split to appropriate sizesAir-dried for minimum 12-24 months depending on speciesStored in covered, ventilated conditionsProtected from rain but allowing airflow |
| Signs of Well-Seasoned Wood: | Cracks or checks visible in the end grainHollow sound when two pieces are knocked togetherBark that falls off easily or is already removedLighter weight compared to fresh woodNo sap or resin visible on the surface |
| Wood Species and Seasoning Times: | Hardwoods (oak, ash, beech): 18-24 months minimumSoftwoods (pine, fir): 12-18 months minimumDense woods need longer seasoning periodsSmaller pieces season faster than large logs |
Prohibited Wood Types
Even in DEFRA-approved stoves, these wood types remain illegal:
Never Burn:
- Treated, painted, or varnished wood
- Construction materials or furniture
- Driftwood or wood from unknown sources
- Green or freshly cut wood
- Wood with visible mold or rot
Garden Waste Restrictions:
- Fresh prunings or green waste
- Leaves, grass, or other organic matter
- Treated garden timber or fence panels

Best Smokeless Fuel for DEFRA Stoves Cambridge
DEFRA-approved stoves can burn all types of approved smokeless fuels, giving you alternatives to wood or allowing you to mix fuel types based on your needs.
Types of Approved Smokeless Fuels
| Anthracite Coal: | Naturally occurring smokeless coalBurns very hot with minimal smokeLong burning time, excellent heat outputHigher cost but very efficient |
| Semi-Anthracite: | Lower grade than full anthraciteGood heat output with clean burningMore affordable than anthraciteWidely available from suppliers |
| Manufactured Solid Fuels (MSFs): | Processed fuel products from various materialsMust display “Authorised for use in smoke control areas”Available in different shapes and burning characteristicsOften designed to mimic coal appearance |
How to Identify Approved Smokeless Fuels
Check Packaging:
- Look for “Authorised for use in smoke control areas” text
- Verify approval symbols or certification marks
- Note the manufacturer and product name
Verify Online:
- Check the DEFRA Approved Fuels database
- Cross-reference product names and manufacturers
- Confirm current approval status
Cambridge Fuel Supplier Recommendation: For reliable supplies of both seasoned wood and approved smokeless fuels, we recommend Logs Direct. They deliver throughout Cambridge and guarantee fuel quality and compliance status.
How to Use DEFRA-Approved Stove Properly
How you operate your DEFRA-approved stove affects both compliance and performance. Poor burning technique can create unnecessary smoke even with approved fuels.
Starting Your Fire Properly
Top-Down Lighting Method:
- Place approved smokeless fuel or seasoned wood as base layer
- Build kindling structure on top
- Light from the top using proper firelighters
- Allow flames to work downward
- Add fuel gradually as fire establishes
Benefits of Top-Down Method:
- Reduces initial smoke production
- Creates better draft and combustion
- Uses less kindling and firelighters
- Establishes cleaner burning faster
Operating for Clean Burning
Air Control Management:
- Open air controls fully during lighting
- Gradually adjust as fire establishes
- Never restrict air supply too much
- Maintain active, bright flames
Fuel Loading:
- Don’t overload the firebox
- Add fuel before previous load burns completely down
- Use appropriate fuel sizes for your stove
- Maintain good air circulation around fuel
Temperature Management:
- Burn hot enough to maintain clean combustion
- Avoid “slumbering” the stove with restricted air
- Watch for minimal smoke from chimney once established
- Maintain active flame patterns
Signs of Good Combustion
What to Look For:
- Minimal visible smoke from chimney after lighting
- Bright, active flames in the firebox
- Clean glass door (if applicable)
- Good heat output with reasonable fuel consumption
- Minimal ash production
Warning Signs:
- Excessive smoke from chimney
- Lazy, orange flames
- Glass door quickly becoming black
- Poor heat output despite fuel consumption
- Strong odors or smoke entering room

Frequently Asked Questions
Can I burn kiln-dried wood in my DEFRA-approved stove?
Yes, as long as the moisture content is verified to be under 20%. Kiln-dried wood often meets this requirement, but always test with a moisture meter to be certain.
What happens if I accidentally burn wet wood?
You’ll likely produce excess smoke, which could result in compliance issues if noticed by authorities. Stop burning immediately, clear the wet wood, and resume with properly seasoned fuel.
Can I mix wood and smokeless fuels in the same fire?
While DEFRA-approved stoves can burn both fuel types, it’s better to use one type at a time for optimal performance. Different fuels have different burning characteristics and air requirements. For best results, burn wood for ambiance and initial heat, then switch to smokeless fuels for longer burns or overnight heating.
How often should I check wood moisture content?
Check each new delivery or batch of wood, and periodically test stored wood, especially after wet weather. Different pieces from the same supply can vary in moisture content.
What’s the best way to maintain consistent heat overnight?
Use approved smokeless fuels. Load the stove properly before bedtime and adjust air controls to maintain steady, clean burning.
With a DEFRA-approved stove, you have excellent options for staying warm and compliant in Cambridge’s new Smoke Control Area. The key is understanding fuel requirements, proper operation, and maintenance needs. By following these guidelines, you can continue enjoying your fire while contributing to cleaner air for all Cambridge residents.
