5 Things to Check Before Booking a Chimney Sweep
Not every chimney sweep is the same, and a quick check before you book can save you from a rushed job, a missed safety issue, or a certificate your insurer won't actually accept. Here's what's genuinely worth confirming first.
1. Are They HETAS Certified?
This is the single most important check. HETAS certification means a sweep has been trained and assessed against a recognised industry standard, and it's what allows them to issue a certificate your home insurer will accept as proof of a compliant sweep. Anyone can call themselves a chimney sweep, certification is what actually backs that up.
If a company won't confirm their certification status clearly, that's worth treating as a red flag rather than an oversight.
2. Are They Fully Insured?
Public liability insurance protects you if something goes wrong during the job, damage to a fireplace surround, an accident on a ladder, or anything in between. A properly run local chimney specialist will have this as standard and won't hesitate to confirm it.
3. Do They Issue a Certificate After the Job?
A written Certificate of Chimney Sweeping isn't just paperwork, it's what most UK home insurers require to validate your policy in the event of a chimney fire. If a sweep doesn't offer one, or treats it as an optional extra, that's a gap worth asking about before you book.
4. Do They Explain What's Actually Included?
"A chimney sweep" can mean very different things depending on who you book. Some visits are a quick brush-through, others include a full visual inspection, a smoke test to check the draw is working, and a proper clean-up afterwards. Knowing exactly what's included, and what costs extra, like a CCTV inspection, avoids surprises on the day.
5. Are They Actually Local?
A lot of "chimney sweep companies near me" searches lead to national directories that route your enquiry to whichever contractor happens to be free, rather than a business that genuinely knows your area. A real local chimney specialist will know the difference between a Victorian terrace flue in Chelmsford and a modern estate stove in Watford, because they work on them every week, and can usually offer faster, more flexible appointments as a result.
