How Much Does Chimney Sweeping Cost in the UK?

A standard chimney sweep in the UK costs £60 to £150, with most homeowners paying around £90 for a single appliance. The price covers a full clean of the flue, an inspection, a sweeping certificate for your home insurance, and clean-up afterwards. This guide covers everything you should know about chimney sweep pricing in 2026, including how often to book, what affects the cost, and when bigger jobs come into play.

Chimney sweep costs by job

Most chimney sweep visits fall into a small number of standard jobs. Here is what each costs in 2026:

The price for a sweep usually includes the sweeping itself, an inspection of the flue and chimney pot, dust sheets and protection of the room, removal of soot, and a sweeping certificate. If you have two open fires or a fireplace plus a wood burner in the same property, most sweeps offer a discount for combining them on one visit, typically 20 to 30% off the second flue.

What affects the price

1. Type of appliance

An open fireplace is the cheapest to sweep. Wood burners and multi-fuel stoves are slightly more because the stove pipe usually needs disconnecting from the flue and reconnecting afterwards, and the inside of the appliance gets cleaned at the same time. Inset stoves, where the appliance is built into the wall, can take longer because of trickier access.

2. Region

City of London and the South East are the most expensive areas for chimney sweeping, with average prices around 25 to 40% above the UK average. Sweeping in the North East, parts of Wales, and Scotland tends to come in below average. London chimney sweep prices typically start at £100, while in Lichfield or smaller market towns they often start at £55 to £65.

3. Condition of the flue

If the flue has been swept regularly, the job is fast and clean. If it has not been touched in five or ten years, expect heavy creosote build-up, possible nesting material, and a longer job. Sweeps usually quote a base price and add a surcharge if they discover something unexpected. Always be upfront about how long it has been since the last sweep so you get an accurate quote.

4. Access

Tall chimneys, awkward roof access, and very tight rooms all add a small premium. Most flat-rate sweep prices assume standard 2 to 3 storey access. A 4-storey townhouse chimney or a building with parapet walls can add £15 to £40 to the standard price.

How often to sweep your chimney

How often you need to sweep depends on what you burn and how much you use the fire. The HETAS guidance is the standard:

If you only use the fire occasionally (a handful of times a year), one sweep at the end of the burning season is usually enough. If you burn wood as your main heat source, a pre-season sweep in autumn and a post-season check in spring is the safest pattern. The end-of-season sweep is the more important one — it removes acidic deposits that corrode the flue over the summer.

Skipping sweeps to save money is a false economy. The leading cause of chimney fires in the UK is unswept flues, and the average insurance claim for a chimney fire runs into the thousands. Many home insurance policies require an annual sweep with a certificate as a condition of cover for properties using solid fuel.

The sweeping certificate

Every reputable sweep issues a written certificate after the job. It records the date, address, type of appliance, fuel used, and any defects spotted. This document is important for two reasons:

• Insurance: Many home insurers require proof of regular sweeping for policies covering solid fuel appliances. No certificate, no payout if the worst happens.
• Property sale: Buyers' solicitors increasingly ask for recent sweep certificates as part of the standard property pack. A run of certificates over recent years signals a well-maintained appliance.

If a sweep does not issue a certificate as standard, find a different one. Membership of HETAS, the National Association of Chimney Sweeps (NACS), the Guild of Master Sweeps, or the Association of Professional Independent Chimney Sweeps (APICS) is a good baseline.

Bigger jobs: liners, pots and bird nests

Sometimes a sweep visit reveals a problem that needs a bigger job. The most common ones:

Bird nest removal

Jackdaws and pigeons love unused chimneys. A nest in the flue can block smoke and is a serious fire risk. Removal costs £85 to £200 and is best done in late autumn (after nesting season — outside the closed bird breeding season, which runs March to August in most cases). A cap or cowl fitted afterwards stops the problem coming back, at £120 to £350.

Chimney liner installation

If the flue is cracked, leaking, or no longer suitable for a new appliance, a stainless steel flexible liner is fitted from the chimney pot down to the appliance. This costs £400 to £1,200 for materials and labour, and is normally done at the same time a wood burner or stove is installed. A liner has a 20-year warranty and significantly improves both safety and efficiency.

Chimney pot replacement

Cracked or missing pots cost £150 to £500 to replace, including scaffolding for safe access. If the chimney stack itself is in poor condition, repointing the brickwork costs £400 to £1,200 and is best done while scaffolding is already up.

CCTV chimney survey

A camera lowered down the flue gives a full picture of the inside of the chimney. This is useful before installing a new wood burner, after a chimney fire, or when buying a property with a flue you cannot otherwise inspect. CCTV surveys cost £100 to £300 and are sometimes included free with a sweep at the start of the season.

What to expect on the day

A typical sweep visit takes 45 minutes to an hour. The sweep arrives with brushes, rods, a powerful vacuum, and dust sheets. They cover the floor and any nearby furniture, seal the fireplace opening with a sheet, and feed brushes up the flue. Modern sweeps use rotary power systems that clean more thoroughly than the old hand-rod method, especially on lined flues.

You will see very little soot in the room itself — most of it falls into the grate or is captured by the vacuum. After sweeping, the sweep inspects the flue, removes the dust sheets, takes the soot away, and issues the certificate. Pay on the day or by invoice within a week.

Tips for the visit:

• Do not light the fire for at least 24 hours before the sweep arrives
• Move pets and small children away from the fireplace area
• Clear ornaments, rugs, and breakables within a metre or two of the fireplace
• If the appliance has a glass door, leave it open if you can

Tips for saving money on chimney sweeping

• Book in spring, not autumn. Demand is highest in September and October, just before the heating season. Booking in April or May usually means lower prices and easier scheduling.
• Combine multiple flues. If you have two appliances at the same address (e.g. open fire downstairs, wood burner in the living room), most sweeps offer a 20-30% discount on the second flue if both are done on one visit.
• Burn well-seasoned wood. Wood with under 20% moisture creates far less creosote than wet wood, meaning the flue stays cleaner for longer and may only need one sweep a year instead of three.
• Fit a cowl after a bird nest removal. A £150 cap stops you paying for nest removal again in two years.
• Get on a regular schedule. Many sweeps offer a 10% discount for booking the next year's visit at the same time you pay for this year's.
• Check insurance requirements. Some home insurers require an annual sweep regardless of how often you use the fire. Skipping a year to save £90 can void cover worth thousands.
• Avoid emergency callouts. Same-day or weekend visits attract a 30 to 50% premium. If your fire is not actually unsafe, it can wait until a normal weekday slot.
