How do I choose a trustworthy chimney sweep?

Compare the public evidence on each profile — how many independent reviews they have and across how many named platforms, the rating and how recent it is, any verified credentials, and the company record. A chimney sweep backed by several named sources is harder to fake than one with a single listing.

Does MyTrustedTraders rank or recommend chimney sweeps for payment?

No. There are no ads and no paid placement. Chimney sweeps are ranked only by the strength of independent public evidence — no one can pay to rank higher, add a badge, or change their reviews.

Where do the reviews come from?

They're imported from named public review platforms and always shown with the source named — they aren't reviews written on MyTrustedTraders. We cross-check the same business across sources rather than creating new reviews.

What should I check before hiring a chimney sweep?

Confirm credentials and insurance directly with the chimney sweep, get a written quote, and run the Cowboy Checker on the business first. MyTrustedTraders helps you shortlist on the evidence — it doesn't replace your own checks before you hire.

How to judge a chimney sweep

Independent, no-ads guidance — the trade-specific checks that matter most, the warning signs, and what to ask before you hire. Use it alongside each trader’s public evidence above.

Verify before you hire

Check the sweep is on the HETAS Approved Sweep register, NACS, APICS, Guild of Master Chimney Sweeps, or Sweep Safe — these are the only independent proof of training, as no law requires a licence.
Ask for a written certificate after the job — most home insurers require one from an accredited sweep; a certificate from an unregistered sweep may void a claim.
Check recent reviews (last 12 months) for volume and comments about tidiness — a professional sweep protects your room with dust sheets and leaves no soot.
Verify they carry public liability insurance — ask for the policy name and number before they arrive.

Warning signs of a cowboy

A sweep who knocks unsolicited, quotes on the spot, and demands cash is a known scam pattern — walk away.
Any sweep who immediately diagnoses a cracked liner, CO leak, or bird-nest blockage without showing you evidence is likely upselling a problem that doesn't exist.
No certificate offered after the sweep — a legitimate professional always issues one; its absence leaves your insurance invalid.
No membership of any accreditation body (HETAS, NACS, APICS, Guild, Sweep Safe) — with no legal licence required, an unaccredited sweep has no verified training at all.

Questions to ask before you hire

Are you on the HETAS Approved Sweep register, or a member of NACS, APICS, the Guild of Master Chimney Sweeps, or Sweep Safe?
Will you issue a sweep certificate after the job, and which accreditation body's certificate is it?
Do you carry public liability insurance — can you share the policy details?
How far out are you booked — can you sweep before the heating season starts?
