HETAS approved chimney sweep - Cleansweep Vac Services

Looking for a Chimney Sweep?

It is recommended by the Guild of Master Chimney Sweeps , HETAS and the Fire Service that you get your solid fuel open fire, oil /gas fire, or multifuel stove's chimney / flue swept at least once a year.

If you have just moved in to a new house you should arrange a chimney sweep before you use the fire for the first time. How often should you sweep your chimney? Read our simple guide.

Avoid a chimney fire, call your chimney sweep!

Whether you burn oil, gas, wood, coal or biomass, your chimney needs regular cleaning in order to burn efficiently and economically. It is crucial to avoid the build up of soot and creosote, seen here in the photos, that can cause a dangerous and costly chimney fire and lethal carbon monoxide poisoning.

Make sure that you are burning seasoned wood, that has dried out for a minimum of 1 year and note that different types of trees take even longer to dry out. For more information check out the frequently asked questions on our sister site GTD Installations Ltd

It is important to get your chimney swept at least once a year if you regularly use your fire, and more often if you are a regular user. If you are unsure when the chimney was least swept; be safe and call an experienced sweep straight away.

We have been sweeping chimneys since 1991 and will supply you with a certficate of sweeping along with your receipt. HETAS certificates are also offered.

It doesn't matter if you have a woodburner, multifuel stove, a kitchen range, oil, gas or open fire or have a twin-wall flue rather than a chimney, it still needs to be regularly swept.

Its the season for a chimney sweep in Letchworth



Summer is hopefully on it's way and you are probably using your garden furniture more than your woodburner now. If you used your stove a lot in Winter then it's good time to get your chimney or flue swept, especially if you burn only wood. It's worth noting than all types of fires now need a carbon monoxide alarm so if you don't have one fitted, then add this to your online appointment booking and we will do it for you.


Our prices will be going up on July 1st so just a couple of weeks left to book online and pay current prices.
