It really depends on what you burn, how often you use it and the size of your flue. If you do not use your open fire or stove very often then once a year is probably often enough.
If you use your fire every day in the Winter months as a source of heating, rather than a 'feel good' experience then ask your chimney sweep for advice or see our recommended guidelines below.
A sweep takes around 30 - 45 mins for chimney or flue liner, depending on how dirty it is.
You should also make sure that you have a carbon monoxide detector fitted and working, in addition to your smoke alarm. Click here to buy one online.

your guys have been great - polite, helpful and tidy. Thank you! - Richard in Hitchin
If you have an old wood burner that was installed before 2010 then it is likely that it doesn't meet current building regulations and safety standards. Your appliance should have a physical connection to the top of the chimney to make sure that gases and soot are fully burnt and don't gather in the chimney causing flammable areas that can cause it to set on fire. Stoves installed after 2010 tend to have a flexible liner fitted, or connect to clay liner blocks and are safer to use as well as burning fuel more efficiently; saving you money as well as the planet.
When stoves are fitted, the installer must make sure that there is access for future sweeping to remove the soot and debris in the chimney or flue. Stoves without a liner must therefore have a sweeping hatch, usually in the register plate. If you do not have access then we will not be able to sweep your chimney but will still be charged for the inspection, advice and certification.
The chimney sweep is not allowed (by law) to un-assemble an installation made by another engineer, in order to sweep the chimney and will, instead, declare it unsafe to use.
Don't forget to get your chimney swept regularly.
Thank you once again for a first class service - Simon in Clothall
You recently cleaned our chimney and did a brilliant job. We will always use you from now on. - Rob in WGC
Coal and wood has now disappeared from the supermarket and the local garage, to prevent the sale of poor quality fuel that releases pollutants into the air that we breathe. Bitumous or house coal has now been banned making the UK burn only smokeless coal and / or seasoned wood. It makes sense to keep our local companies in business and to keep your carbon footprint as small as it can be. Here are local fuel suppliers in Hertfordshire that we ourselves use and trust.
Wood supplies are low at the moment but try:
