Burning solid fuel in the home

Solid fuel burning in our homes

The common ways we burn solid fuels in our homes are using open fireplaces and wood burning / multifuel stoves. This page gives information on purchasing, installing, and maintaining solid fuel appliances. It also provides information on burning different types of fuels. Using this information will help to protect the health of you, your family and others in your community.

Health impacts of domestic burning

Burning solid fuels at home is a major contributor to a type of pollutant called fine particulate matter both indoors and outdoors. The common name for this type of pollution is Particulate Matter 2.5 (PM2.5). This consists of tiny particles or droplets in the air that have a diameter of less than 2.5 micrometres. This is about 3% of the diameter of a human hair. It's not visible to the naked eye, so even 'smokeless' fuels and appliances may be causing this type of pollution.

PM2.5 has been identified by the World Health Organization as the most harmful to human health. It can cause illnesses such as asthma, heart disease, strokes, and lung cancer. Current evidence suggests there is no safe level of PM2.5.  

Buying a solid fuel appliance for your home

The Ecodesign regulations came into force on 1st January 2022. From this date, only stoves that comply with Ecodesign standards can be sold. These new efficiency and emission standards improve the level of emissions from solid fuel appliances. An Ecodesign ready wood burner produces up to 90% less emissions than an open fire, and up to 80% less than a stove manufactured over 10 years ago. The Ecodesign also increases the burning efficiency (over 70%) of the fire, which creates more heat with less fuel.

You should select a solid fuel appliance that:

This will ensure that the appliance you choose is compliant with the requirements of the 2022 Ecodesign regulations. Some of these will also meet and exceed the standards for a DEFRA approved stove.

DEFRA Approved Stoves  

There are no Smoke Control Areas (SCAs) in Cornwall. This means you do not have to purchase a DEFRA approved stove. However, using one will help to reduce the amount of smoke that your appliance produces.

The difference between a DEFRA approved and Ecodesign stove

The Particulate Matter (PM) emission limit for Ecodesign stoves is 55% percent lower than the limit for DEFRA approved stoves. This means Ecodesign stoves are better for your health and the environment.

Installing a solid fuel appliance

It is a legal duty to notify Building Control of your solid fuel appliance installation. This can be done by either:


You can make small changes such as:

  • sourcing fuel which displays the 'Ready to Burn' logo
  • using dry seasoned wood
  • reducing how long you have your fire lit

Making these changes can provide benefits such as helping to:

  • Improve the air we all breathe by reducing the amount of pollution produced (#BeAirAware)
  • Keep you and your family safe by reducing the risk of chimney fires.
  • Get the most out of your open fire or appliance so that it performs better. This will help you use less fuel to produce more heat.


One wet log can contain up to one pint of water! Burning wet wood doesn’t give off as much heat and produces lots of smoke and tar which can damage your appliance and harm your health.

All wood that is sold must be certified as 'Ready to Burn'. This demonstrates that the wood has a low moisture content.

Ensure any wood you source is stored in a dry area for at least 2 years before burning.

When is my wood ready to burn?

Check for signs your wood is ready to burn by completing the following checks:

  • Weight – when comparing similar sized logs and the same species, if the log is heavier this can indicate it is still wet
  • Sound – a hollow sound when tapping indicates dry logs
  • Cracked ends – can indicate dry logs
  • Bark – the looser the bark the drier the log
  • Colour – dry wood can be lighter in colour

Looking to source larger quantities of ready to burn wood? If so, use the local search tool to find a Woodsure quality assured wood fuel supplier near where you live.

Always avoid burning treated material, such as wood which has been:

  • painted
  • stained
  • chemically treated

(These may include old furniture, pallets and medium density fibreboard.) These release dangerous pollutants which could have a serious impact on your health.

Manufactured Solid Fuels

Manufactured solid fuels (MSF) are any solid fuels made from:

  • coal
  • wood
  • plant-derived materials
  • waxes
  • petroleum products,

which are mixed with other ingredients. All MSFs need to display the 'Ready to Burn' logo. See the list of certified MSFs.


All sales of traditional house / bituminous coal will be banned in England from 1st May 2023. (Currently, only coal merchants that are registered as a member of the Approved Coal Merchants Scheme are able to sell loose coal until the above date.)

Other types of coal will continue to be available as they produce less smoke. These include:

  • anthracite
  • semi anthracite
  • low volatile steam coal

Maintenance of your solid fuel appliance

Solid fuel appliances such as wood burners and multifuel stoves should have an annual service. This should include cleaning the flue. 

If you use an open fire, get your chimney swept regularly. It is advisable to get your chimney swept at least:

  • twice a year when burning wood
  • once a year when burning smokeless fuels


Garden bonfires produce smoke and smells. This can annoy neighbours and damage the environment. They can also damage your health through releasing harmful pollutants into the air.

There are no bylaws in Cornwall concerning domestic bonfires. There are no specific times of day when bonfires are prohibited. However, it is strongly recommended to avoid having bonfires and disposing your garden waste in other ways. For example:

Staying warm and well

At the current time, we recognize many of our residents are trying to stay warm and well. Cornwall Council has brought together in one place all the support for residents struggling with the cost of living. 

We have lots of advice and information about:

  • staying warm and well
  • how to apply for grants to improve the warmth of your home

Please see our Winter Wellbeing service.
