Chimneys and barbeques (BBQs)
Chimneys and BBQs that do not have a building or shed chimney are not covered by Smoke Control legislation, but when using these you should:
- show consideration to your neighbours
- not create excessive smoke that could contribute to poor air quality or be a statutory nuisance
Installing a solid fuel burner or boiler appliance
Installing a solid fuel burner is not the best environmental option for domestic home heating. It is not recommended next to tall buildings or amongst the highest population density. Consider cleaner home heating options.
Legal requirements
It's a legal requirement for solid fuel burners and boilers to be fitted in accordance with Part J of the Building Regulations.
If your installer has been accredited as a competent person no action is needed after the installation is complete. If they're not accredited, or you have fitted it yourself, you'll need to get building regulation approval.
HETAS runs the most widely used competent persons scheme. You can search for HETAS-approved installers on their website. There are also other competent person schemes.
Ideally, when buying a home with a solid fuel appliance you should ask to see evidence that it:
- has building regulations approval or
- has been installed by a member of a competent persons scheme such as HETAS
Building regulations are there for your safety. Solid fuel appliances can be dangerous if they're not installed correctly and well maintained.
Badly fitted appliances:
- can risk smoke and carbon monoxide building up in the home
- could be too close to electric wiring and plug sockets
Chimney condition
If your chimney has not been used for some time it's essential to have it inspected and swept before using solid fuels. Defective chimneys can leak smoke and dangerous gases such as carbon monoxide into your home.
Maintenance and chimney sweeping
Solid fuel appliances may appear simple, but they require regular maintenance to stay safe, clean and efficient.
You should ensure:
- ash is removed at least once a day
- the flue ways and throat plates are cleaned at least once a month
- grates and firebricks are in good condition
Your installer will be able to provide an appropriate maintenance schedule.
If other people are occupying your home, for example, if you rent out the property or have a carer, you must provide guidance on using and maintaining your solid fuel appliance.
It's essential to keep your chimney clean by sweeping it at least once a year. You can find a chimney sweep using:
Fuel choice
While all solid fuel burning produces some smoke, it's essential to ensure the fuel choice reduces this risk.
Poor quality fuels may:
- burn inefficiently
- create pollution
- cause harmful particles indoors and outdoors
- damage your appliance
The most common wood fuel is seasoned or kiln-dried logs, although the various types of wood available burn in different ways. Fuel suppliers can provide ready-to-burn advice.
You should also be aware that wood needs to be seasoned (dried) before it can be burnt, which can take up to 2 years.
Fuel suppliers have a duty to provide wood that:
- is already seasoned or
- has the ready-to-burn logo
Logs should be stored in a well-ventilated stack in a sunny position before being taken indoors.
To help us manage elm disease in the city, don’t buy logs for fuel if the supplier cannot guarantee the wood isn't elm.
Other wood fuels include wood chips and pellets which are commonly used in more complex appliances such as wood fuel boilers.
Before burning, solid fuels should be kept dry by keeping them indoors or under a secure cover. They are a fire risk if stored next to a hot stove.
Wet fuels including recently felled timber burn inefficiently and can create smoke.
Discarded wood
There are many sources of discarded wood, for example:
- clearing up after a storm
- fallen branches
- damaged fence panels
- carpentry off-cuts
- old furniture
- wood from skips
In the past, waste wood used to decompose in a landfill and produce methane. Local authorities no longer landfill waste. Not all wood is suitable for burning at low temperatures you should take great care before using it as a fuel.
Common issues in using wood
Wood needs to be left to dry (seasoned) before it can be burnt. Burning wet, freshly felled or rotten wood can produce large amounts of smoke.
Wood can be coated with preservatives such as varnish, creosote or lead paint. If burned, toxic fumes including metals and organics can be released into the air. Solid fuel burning such as logs releases carbon dioxide into the air within a few hours.
It takes decades for growing trees to reabsorb this carbon. Ready-to-burn log supplies usually need to be kiln-dried and transported by truck. Wood burning in an urban area (remote from a farm or forest) is not carbon neutral.
