TL;DR — Chimney Cleaning Cost At A Glance
- Most people pay £60–£130 to have a chimney swept, with the typical bill landing around £90–£120 for a single flue.
- London and the South East run roughly 20% higher, so expect £75–£150 in the capital.
- The main cost drivers are the appliance type, the state of the flue, chimney height and access, and whether a bird's nest needs removing.
- A wood-burning or multi-fuel stove usually costs a little more to sweep than an open fire, because of tar and creosote build-up.
- Sweeping a second flue in the same visit is cheaper (around £40–£60 extra) than booking two separate call-outs.
- A professional sweep should issue a certificate of sweeping, which many home insurers and holiday-let policies ask for.

How Much Does Chimney Cleaning Cost In 2026?
A standard chimney sweep in the UK costs £60–£130 for a single flue, with most households paying around £90–£120. London and the South East add roughly 20%, pushing the typical figure to £110–£150. The price covers a trained sweep cleaning the flue, checking that it's clear and drawing correctly, and issuing a certificate confirming the work.
The reason the range is fairly narrow is that a routine sweep of a well-maintained chimney is a predictable job. Where the price climbs is when the flue hasn't been cleaned in years, when tar and creosote have hardened inside a stove flue, or when a bird's nest, debris or a collapsed liner is found. A sweep who arrives to find a jackdaw nest packed into the pot will charge more, because clearing it is slower and messier than a normal sweep.
Two things push the total up quickly. The first is appliance type: an open coal fire, a sealed wood-burning stove and a gas fire with a flue each need slightly different handling. The second is frequency — a flue swept every year stays quick and cheap to clean, while one left for several seasons builds up deposits that take longer to shift and raise the risk of a chimney fire.
Here's what you can expect to pay:
| How you book | Rest of UK | London & South East |
|---|---|---|
| Single flue sweep | £60–£100 | £75–£120 |
| Typical all-in price | £90–£120 | £110–£150 |
| Additional flue (same visit) | £40–£60 | £50–£75 |
| Bird's nest removal (add-on) | £70–£150 | £90–£180 |

Chimney Cleaning Cost By Appliance Type
Sweeps usually price by the flue and the type of appliance it serves, because each burns differently and leaves different deposits. Here's a typical breakdown:
| Appliance / chimney type | Typical price (rest of UK) | London |
|---|---|---|
| Open fireplace (coal or wood) | £60–£90 | £75–£110 |
| Wood-burning / multi-fuel stove | £70–£110 | £85–£130 |
| Gas fire with a flue | £60–£90 | £75–£110 |
| Inglenook or large open chimney | £90–£130 | £110–£160 |
| Aga or Rayburn flue | £80–£120 | £100–£150 |
| Second flue in same visit | £40–£60 | £50–£75 |
Heavy tar glazing inside a stove flue, a chimney that needs a smoke-draw test, or a CCTV inspection to check a suspected fault can add £30–£80 to the job.
What Affects The Cost Of Chimney Cleaning?
Several factors decide where you land in the ranges above.
1. The Type Of Appliance
An open fire is quick to sweep. A wood-burning or multi-fuel stove often takes longer because the sweep must remove the baffle plate, clean the flue and reassemble the stove, and because burning wood at lower temperatures leaves sticky creosote that's harder to shift.
2. Chimney Condition And Build-Up
A flue swept every year stays easy to clean. One left for several seasons — or burned on damp, unseasoned wood — accumulates soot and tar that need extra passes and sometimes a power (rotary) sweep, which costs more.
3. Blockages And Bird Nests
Jackdaws and other birds nest in unused pots, and nests can pack a flue solid. Removing a nest is charged on top of the sweep, typically £70–£150, and may need a cowl or bird guard fitted afterwards to stop it happening again.
4. Chimney Height And Access
Tall chimneys, awkward roof access and multi-storey homes slow the job and may need extra equipment. A ground-floor stove in a bungalow is cheaper to sweep than a fourth-floor flat's flue.
5. Number Of Flues
Many older homes have several flues. Sweeping two or more in one visit is far cheaper per flue than booking separate appointments, because the call-out and set-up are shared.
6. Your Location
London and the South East run roughly 20% higher than the North of England, Wales and Scotland, reflecting higher labour and travel costs.
What's Included — And What's Not
| Typically included in a chimney sweep | Usually charged separately |
|---|---|
| Sheeting up and protecting the hearth and surrounding floor | Bird's nest or major blockage removal |
| Sweeping the flue with brushes and rods (or a power sweep where needed) | Fitting a chimney cowl or bird guard |
| A basic visual check that the flue is clear and structurally sound | CCTV camera inspection of the flue |
| Removal of the soot and debris collected during the sweep | Smoke-draw or integrity testing beyond a basic check |
| A certificate of sweeping for your records and insurer | Any repairs to the liner, pot or brickwork |
Confirm whether a certificate and a basic draw test are included, as these are what most people actually need from the visit.
Can You Do It Yourself?
You can buy a chimney-sweeping brush and rod set for around £20–£40 and clean a straightforward, easily accessed flue yourself. For a lightly used open fire that's swept regularly, careful DIY is possible and saves the call-out.
The trade-offs are safety and thoroughness. A professional sweep knows how to clean a stove flue without damaging the liner, checks for cracks, blockages and carbon monoxide risks that an amateur would miss, and leaves the room clean rather than covered in soot. A sweep also issues a certificate, which a DIY clean cannot — and many home insurance and holiday-let policies require one. Where a flue is tall, tarred, blocked or serving a wood burner, a professional is the safer and often cheaper choice once the risk of a chimney fire is factored in.
How To Save Money On Chimney Cleaning
- Sweep every year rather than letting deposits build up — regular flues are quick and cheap to clean.
- Book a second flue in the same visit to share the call-out cost.
- Burn dry, seasoned wood (under 20% moisture) so the flue stays cleaner for longer.
- Fit a bird guard after a nest removal to avoid paying for the same problem next season.
- Book off-peak in late spring or summer, when sweeps are quieter than the autumn rush.
- Clear the hearth and move furniture before the sweep arrives so paid time goes on the flue, not set-up.
How To Hire A Good Chimney Sweep
Choose a sweep who belongs to a recognised trade body such as HETAS, the National Association of Chimney Sweeps (NACS), the Guild of Master Chimney Sweeps or APICS — membership means training and a code of practice. Confirm they're insured, ask whether they issue a certificate of sweeping, and check they'll do a basic draw test and flag any faults. Read recent reviews and get the price in writing, including any add-ons for nest removal or a cowl.
With Fantastic Services, you get vetted, insured sweeps, a certificate for your records, transparent pricing and online booking, so your fire stays safe and efficient through the heating season.

Frequently Asked Questions
How Much Does It Cost To Sweep A Chimney?
A single flue costs £60–£130 across most of the UK, with the typical bill around £90–£120. London and the South East add roughly 20%, so expect £75–£150 in the capital. Bird's nest removal and extra flues cost more.
How Often Should A Chimney Be Swept?
At least once a year for most homes. Wood and multi-fuel appliances used heavily through winter should be swept twice a year, and gas or oil flues once a year. Regular sweeping keeps the flue safe and cuts the risk of a chimney fire.
Is A Chimney Sweep Certificate Needed For Insurance?
Often, yes. Many home insurers and most holiday-let policies ask for a certificate of sweeping as proof the flue has been maintained. A professional sweep issues one after every clean, which a DIY sweep cannot.
How Long Does Chimney Sweeping Take?
A routine sweep of a single flue takes about 45 minutes to an hour. A stove that needs dismantling, a heavily tarred flue or a blockage takes longer. Clearing access beforehand keeps the visit quick.
Does Chimney Sweeping Make A Mess?
It shouldn't. A professional sweep sheets up the hearth and uses a sealed vacuum, so soot is contained. Modern sweeping is far cleaner than the traditional image, and the sweep clears away the debris collected.
Why Does A Wood Burner Flue Need Sweeping More Often?
Wood burned at lower temperatures, or damp unseasoned logs, produce creosote and tar that coat the flue and can ignite. Heavily used stoves are best swept twice a year, and burning dry, seasoned wood keeps deposits down.
What Happens If A Chimney Is Not Swept?
A neglected flue can block with soot, tar or a bird's nest, which stops it drawing, pushes smoke and carbon monoxide back into the room, and raises the risk of a chimney fire. Annual sweeping is the simplest way to avoid all three.
