Let’s talk about a burning question (pun intended). You've perhaps wondered "How often should I actually be sweeping my chimney?" As a professional chimney sweep with years of experience, I've seen plenty of chimneys. From spotless to dangerously dirty.'
But here's the thing: there’s lots of advice out there. From sources such as HETAS and other organisations to armchair experts, it can be hard to know who to trust. On top of that, a chimney sweep, like any other tradesman, isn’t someone you want to pay for when unnecessary. But, you still want to stay worry free and have a chimney that's safe.
The easy answer is this. At the very least, you should have your chimney swept once a year. Depending on the fuel you use and/or manufacturers' instructions, you may need to have it swept more often. Source
Why is that the recommended amount though? Is sweeping less regularly actually that dangerous? Well grab a cuppa and let’s find out.

The Crucial Role Of Your Chimney
To understand the importance of chimney sweeping, let's take a look at the chimney itself. We'll see how everything works, what the risks are and why sweeping once a year is recommended.
The chimney is often overlooked, but it plays an essential role. A well-maintained chimney ensures any smoke and harmful gases can escape fast. Imagine it as the reliable pipes in your home’s plumbing – out of sight but vital.
If left unchecked, what could develop in your chimney?
Soot. Soot accumulates every fire you light. You can reduce soot buildup by burning correct fuels and keeping the air vents open enough. But, it will still accumulate over time.
Creosote. It come's in a few stages, from a hardened rock like substance to black tar. Think of it like plaque in arteries; if left untreated, it poses a serious fire hazard.
Blockages. They come in various forms, but here in the UK it’s often in the form of bird nests. However, even cobwebs can reduce the airflow to dangerous levels if there's enough of them.
What would the risks be if left unswept for a long period of time?
Chimney Fires: A chimney with lots of soot or creosote can easily start a chimney fire. Whilst not as frequent as decades ago, it’s still a problem. In fact, between April 2021 and March 2022 there were 2,608 reported chimney fires in England. Source
Carbon Monoxide Poisoning: Blockages and buildup in your chimney can lead to a silent but deadly guest – carbon monoxide. It's odourless, colourless and highly dangerous, especially to young children or the elderly. Worse still, it can build up in the body over time, so even a small constant leak is dangerous.
Note: It’s an essential to have a carbon monoxide detector in the same room as your solid fuel appliance. That includes woodburners, multi fuel stoves and open fires.
Reduced Efficiency: A dirty chimney can dampen the performance of your stove. Meaning you'll be wasting money on fuel not burning correctly. As soot builds up, it gets more and more difficult for the chimney to evacuate the flue gases properly.
What Could Be The Signs Something’s Wrong?
What should you do if your carbon monoxide detector goes off? Close the stoves air vents and don't add any fuel. Then get outside opening doors and windows to ventilate your home. Afterwards get your chimney and stove looked at straight away. On top of that, a smoky living room or lingering burnt smell are warning signs. A fire that isn't burning right is another red flag.
In a nutshell, your chimney is more than just a stack of bricks. It’s an integral part of your home’s safety and comfort system. Ignoring its maintenance is like ignoring a leaky roof – it only leads to bigger problems. So, let’s keep that chimney clean and your fires burning bright and safe!
The Right Chimney Sweep Schedule
Now that we understand the crucial role of a chimney, let's talk timing. How often should you be calling in the chimney sweep?
General Sweeping Recommendations:
Annual Tradition: At a minimum, get your chimney swept once a year. It’s like an annual health check-up – preventive care to keep everything running smoothly.
More is Better: Using your stove on at weekends and a few weeknights, and only during colder months, is classed as average usage. But,
Why Would You Require More Frequent Chimney Sweeping?
Type of Fuel: Different fuels leave different amounts of soot and residue. Wood, especially if it’s not properly seasoned, can lead to more creosote. Smokeless coal, on the other hand, can leave different types of deposits. If you have a flexible metal liner, the manufacturer may require also sweeping more often if using certain fuels such as smokeless coal.
Burning Habits: How often and how hot you burn your stove can change the game. Ensure you fully open the vents for around an hour every time you start your fire. This helps warm the chimney and gets the gases and smoke to escape quickly. Closing your air vents too early or too much can also starve the chimney of enough air, leading to creosote build up.
Best Times to Sweep:
Post-Winter: After a season of heavy use is an ideal time to sweep your chimney after the busy winter season.
Pre-Autumn: Getting a sweep before you start using your stove again can ensure you’re ready for the season.
Remember, scheduling regular chimney sweeps is not just ticking a box. It’s about taking care of your home, and ensuring those warm, crackling fires through the chilly seasons are safe. So, mark your calendar and keep your chimney in the clear!
