5 Best Chimney Sweep Providers in London (2026)

Independently ranked by our review of ratings, reviews and reputation · How we chose

By Brad Smith, Home Services Expert · ✓ Data verified July 2026 · 7 min read

A blocked flue isn't just inconvenient, it's a fire and carbon monoxide risk, which is why most chimney sweep providers in London on this page build a smoke test or CO2 check into an ordinary visit. Every one of them holds a perfect 5.0 Google rating, so the real gap is depth of record: the top name carries 373 reviews against as few as 80 for the newest entrant, out of 949 logged between them.

Short answer: H Firkins & Sons leads this list with a perfect 5.0 average across 373 Google reviews, the deepest and highest-confidence track record among London's chimney sweeps. SweepSmart follows closely with 258 reviews and the same 5.0 average. One entry, BaMaPa Clean, turns out to be a pressure-washing and gutter-cleaning company rather than a chimney sweep, and we've flagged that honestly below. Most companies here quote after a short phone call rather than a fixed online price.

Our take: Second on review volume and matching the top score exactly. The HETAS registration and digital photo reports are the kind of paperwork trail worth having if you ever need to prove the chimney was serviced.

Our take: Ties for the top rating with the two above it, but on fewer reviews, which is why it ranks third. The smoke and CO2 testing add real safety value beyond a basic sweep.

BaMaPa Clean | Pressure Washing | Commercial Cleaning | Gutter Cleaning

5.080 Google reviews

BaMaPa Clean is a London pressure-washing and multi-service cleaning company covering gutters, driveways, patios, roofs, carpets, and wood floor sanding, run largely by Szilard. It doesn't list chimney sweeping as a service, and none of its reviews describe chimney work.

What people praise

Gutter clearing documented with drone photos to confirm the job was done
Roof and driveway cleaning results described as transforming decades-old properties
Consistently described as doing extra work beyond the original quote at no additional charge

Worth knowing

Not a chimney sweep, so anyone who needs a flue actually swept should call one of the four specialists above instead

Our take: The odd one out here: a genuinely well-reviewed exterior cleaning company, but chimney sweeping isn't among the services it lists or that its reviewers describe. It likely surfaces in this search because gutter and roof cleaning sit loosely alongside chimney-adjacent home maintenance.

How we scored this list

Rating is each company’s live Google average. Review volume measures how many customers have actually left a rating, shown as a percentile against similar London chimney sweeps. Confidence blends the two, so a 5.0 average built on 300-plus reviews earns more trust than the same score from 30. Recency tracks how fresh the latest reviews are. None of these five paid to appear or to rank higher; a business can only pay for the separate Featured Partner badge.

What does a chimney sweep cost in London? (2026)

Price depends mainly on how many chimneys need sweeping, whether it’s a routine annual clean or a first sweep after years of neglect, and whether extras like a smoke test, CO2 alarm check, or bird’s nest removal are bundled in or charged separately. Most companies on this list quote after a short phone call rather than a fixed online price, so ask what’s included before comparing two quotes.

Serving all of London

H Firkins & Sons and SweepSmart both cover wide swathes of north London, from Southgate and Enfield out toward Hertfordshire and Essex. Barnet Chimney Sweeps overlaps that same north London and Herts patch, while Pearce & Son works south east London from Bromley to Forest Hill and Eltham. Wherever you’re searching from, north or south of the river, one of the four genuine chimney specialists here realistically covers you.

What to ask before you book a chimney sweep

Is a smoke test or CO2 alarm check included, or is that an extra charge?
Are you HETAS registered or a member of a recognised guild, and can you show certification?
Will I get a written or photographed report after the sweep, for insurance or a house sale?
How long has it been since the flue was last swept, and does that change the price?
Do you offer a set arrival window, and will I get a text when you’re on the way?

Frequently asked questions

How often should a chimney actually be swept?

Most sweeps recommend once a year for a chimney used regularly through the season, and even an unused flue is worth checking every few years for nests or blockages, as a couple of reviewers here discovered the hard way.

Do I need a sweep certificate for a house sale?

Often yes. Several reviewers here booked a sweep specifically because a sale was in progress and a certificate was requested; H Firkins & Sons and SweepSmart both mention providing documentation after the visit.

Are these rankings paid?

No. Rankings come from public Google data. A business can pay to be a Featured Partner, which gets it a badge and top placement, but that never changes another business’s score or position.

How did you choose these five chimney providers?

We pulled every business Google surfaces for London chimney sweep searches, then ranked them on their live rating, how many customers have actually reviewed them, and how recently. One result turned out to be a pressure-washing company rather than a chimney sweep, and we’ve said so rather than pretending otherwise.

How often is this page updated?

We refreshed the data behind this list in July 2026 and recheck it periodically as ratings and review counts change.

The bottom line

H Firkins & Sons is the safe default: the deepest review record on this list, a genuinely long trading history, and technicians who go beyond a basic brush-through with drone inspections and photo reports. If you need someone fast for a same-week emergency sweep, SweepSmart’s response times stand out too. Either way, skip BaMaPa Clean for this particular job; it’s a good pressure-washer, not a chimney sweep.
