Do I need a chimney for a log burner?
No — a twin-wall insulated flue can be installed through the wall or roof if you don't have a chimney. This adds £1,000–£2,000 to the total cost.
How Much Does a Log Burner Cost in 2026?
A log burner adds warmth, character, and ambiance. In 2026, all new wood burners must be Ecodesign compliant (SIA approved) to meet clean air regulations. Costs include the stove, flue liner, and HETAS-certified installation.

Yes, but you must use a DEFRA-exempt (SIA approved) Ecodesign stove. Most new stoves meet this standard. Check your local authority's clean air zone map.
