Regular chimney sweeping is essential for safety and efficiency. Here is what chimney sweeps charge in the UK, what the service includes, and how often you need one.

| Service | Average Cost |
|---|---|
| Standard chimney sweep | £60–£90 |
| Sweep + smoke test | £70–£110 |
| Sweep + CCTV inspection | £100–£180 |
| Bird nest removal | £80–£150 |
| Chimney cowl fitting | £60–£120 (plus cowl) |

| Dual chimney sweep (2 flues) | £100–£160 |
Most sweeps take 30–45 minutes. Prices are higher in London and the South East by 20–30%.
Frequency depends on fuel type:
- Wood/multifuel stoves — Sweep at least once a year, ideally before the heating season. Heavy users should sweep twice a year.
- Open fires (coal) — Sweep at least twice a year.
- Gas fires — Annual inspection recommended, though less soot builds up.
- Oil — Once a year.
Signs you need a sweep now:
- Smoke coming back into the room
- Yellow or brown staining above the fireplace
- A strong unpleasant smell when the fire is not lit
- Birds nesting in the chimney pot
A blocked or dirty chimney is a serious fire and carbon monoxide risk. Never ignore these warning signs.
A professional chimney sweep should:
1. Inspect the fireplace and flue for visible damage
2. Sweep the full length of the chimney using rods and brushes
3. Conduct a smoke test to confirm the flue draws correctly
4. Check the cowl or cap is in place and undamaged
5. Issue a certificate — this is important for insurance and home sales
Always use a HETAS-registered or Guild of Master Chimney Sweeps certified professional. They carry public liability insurance and follow safety standards.
