Open Fireplaces in Cambridge: What You Can (and Can’t) Burn from 2026

If you have an open fireplace in Cambridge, you’re probably wondering what the new city-wide Smoke Control Area means for your cosy winter fires. The good news is straightforward: you can absolutely continue using your open fireplace – but there are clear rules about what you can and can’t burn.

As chimney professionals who’ve been helping Cambridge residents navigate Smoke Control Area requirements since the original areas were established in the 1960s, we know that open fireplace compliance is actually the most straightforward of all the heating options. Here’s everything you need to know.

The Simple Rule for Open Fireplaces

From January 2026, if you have an open fireplace in Cambridge, you can only burn approved smokeless fuels. This rule is clear, consistent, and has been successfully operating in parts of Cambridge for decades.

What this means:

  • No wood burning (except small amounts of dry kindling to start fires)
  • No house coal
  • No household waste or inappropriate materials
  • Only fuels specifically approved for use in Smoke Control Areas

The reason for this restriction is simple: open fireplaces don’t have the controlled combustion systems that modern stoves use to burn wood cleanly. Without these systems, wood burning in open fires produces significantly more smoke and particulate emissions.

What You CAN Burn

Approved Smokeless Fuels

All of these are permitted in open fireplaces within Smoke Control Areas:

Anthracite CoalNaturally smokeless, burns very hot and longExcellent heat output, minimal ash productionMore expensive but very efficientBurns with a blue flame, virtually no visible smoke
Semi-Anthracite CoalSimilar properties to anthracite but slightly lower gradeGood heat output with minimal smokeMore affordable than full anthraciteBurns cleanly with little visible emission
Low Volatile Steam CoalsSpecially processed to reduce smoke emissionsGood for sustained, steady heatApproved varieties clearly marked on packagingBurns efficiently with minimal residue
Manufactured Solid Fuels (MSFs)Processed fuel products made from various materialsMust display “Authorised for use in smoke control areas” on packagingAvailable in various shapes: ovals, beans, nuggetsOften designed to mimic coal appearance and burning characteristics

How to Identify Approved Fuels

Check the packaging: Look for clear text stating “Authorised for use in smoke control areas” or “Approved for smoke control areas”

Verify online: Check the official DEFRA database

Ask your supplier: Reputable fuel merchants should be able to confirm approval status

Look for recognisable brands: Many established fuel manufacturers clearly mark their approved products

What You CAN’T Burn

Prohibited Materials

Any Wood (except kindling)Seasoned, unseasoned, kiln-dried – all prohibited in open firesThis includes logs, wood pellets, and wood briquettesException: small amounts of dry kindling to start fires
House CoalTraditional bituminous coal produces excessive smokeNot approved for Smoke Control AreasMuch higher emissions than smokeless alternatives
Household WastePaper, cardboard, packaging materialsCreates toxic emissions and excessive smokeIllegal and dangerous to burn
Treated WoodPainted, varnished, or preserved timberFence panels, furniture, construction materialsReleases toxic chemicals when burned
Other Inappropriate MaterialsRubber, plastics, textilesGarden waste when wet or unsuitableAny material not specifically designed as approved fuel

Why These Restrictions Matter

Open fireplaces lack the controlled air supply and secondary combustion systems found in modern stoves. When inappropriate materials are burned:

  • Incomplete combustion creates excessive smoke and particulates
  • Toxic emissions can be produced from treated materials
  • Higher pollution levels affect local air quality
  • Increased risk of chimney fires from tar buildup

The Kindling Exception

You ARE permitted to use small amounts of dry wood kindling to start your fire, even in a Smoke Control Area. This practical exception recognises that getting smokeless fuels to ignite can be challenging without proper preparation.

Guidelines for kindling use:

  • Use only dry, seasoned wood
  • Keep quantities small – just enough to establish initial combustion
  • Transition to approved smokeless fuel once flames are established
  • Avoid creating excessive smoke during the lighting process

Best practice for lighting:

  1. Place a layer of approved smokeless fuel in the fireplace base
  2. Build a small kindling structure on top
  3. Light the kindling and allow flames to establish
  4. The burning kindling will ignite the smokeless fuel below
  5. Add more approved fuel gradually as needed

Making the Switch: What to Expect

If you currently burn wood or house coal in your open fireplace, switching to approved smokeless fuels involves some adjustments:

Burning Characteristics of Smokeless Fuels

Heat Output:Modern smokeless fuels often provide more consistent, longer-lasting heat than traditional coal or wood
Appearance:Many manufactured fuels are designed to look similar to coal and provide attractive flames
Lighting:May require different techniques – smokeless fuels can be slower to ignite than wood
Ash Production:Generally less ash than wood, making cleanup easier
Odour:Much less smoke means reduced odours both indoors and for neighbours

Cost Considerations for Smokeless Fuels

Per unit cost:Smokeless fuels are typically more expensive per bag than house coal or logs
Efficiency: Higher energy content often means you need less fuel overall
Heat duration: Longer burning times can offset higher initial costs
Convenience:Less frequent refueling needed compared to wood

Tips for Better Burning with Smokeless Fuels

Lighting Technique

Proper preparation: Ensure your fireplace is clean and ash levels aren’t excessive
Good airflow: Open dampers fully and check that air vents aren’t blocked
Quality firelighters: Use proper firelighters rather than accelerants
Patience: Allow time for smokeless fuels to properly ignite before adding more

Fuel Management

Don’t overload:Add fuel gradually rather than filling the fireplace completely
Size matters:Use appropriately sized fuel for your fireplace opening
Storage:Keep smokeless fuels dry to maintain their efficiency
Quality suppliers: Source from reputable dealers who guarantee fuel standards

Maintenance for Clean Burning

Regular sweeping: Annual minimum, more frequently for heavy users
Clear airways:Ensure chimney draw isn’t restricted by blockages
Damper operation: Learn to control airflow for optimal burning
Ash removal:Clear ash regularly but leave a thin base layer for insulation

Modern smokeless fuels are designed to provide attractive flames and good heat output. While the experience is different from wood, many users find the reduced smoke and longer burn times preferable.

No. In a Smoke Control Area, you cannot burn wood in an open fireplace except for small amounts of kindling to start fires.

You’ll need to find alternative uses for wood logs – perhaps giving them to someone with a DEFRA-approved stove, using for outdoor fires, or storing until you can install a compliant stove.

Properly burning smokeless fuel should produce minimal visible smoke once established, provide good heat output, and burn steadily without excessive sparking or spitting.

Planning Your Transition

Before January 2026

Test different fuels: Try various approved smokeless options to find what works best in your fireplace
Source reliable suppliers:Establish relationships with fuel merchants who stock approved products
