How Much Does a Soffit Replacement Cost in 2026? (UK)
Replacing tired or rotten soffits costs roughly £60–£100 per metre fitted in 2026, rising to £100–£150 per metre when the fascias come off at the same time — which is usually the smart move, because the scaffolding is the expensive part. A full fascia-and-soffit replacement on a typical 3-bed semi runs £2,800–£4,500 including scaffolding and waste removal. The biggest price drivers are access, whether rafter ends need repairs once the old boards come off, and whether you replace or cap. This guide breaks down 2026 prices by house type and shows where to save.
Soffit & Fascia Replacement Cost by House Type
Prices below are for full uPVC fascia-and-soffit replacement — old boards stripped, rafter ends checked, new boards, over-fascia ventilation and new guttering — including scaffolding and waste removal.
Soffit-only replacement (fascias left in place) prices at £60–£100 per metre; capping sound timber with uPVC costs £50–£80 per metre but should never be used over damp or rotten boards. London and the South East sit 15–25% above these ranges.
Five Things That Move Your Quote
- Scaffolding and access. £600–£1,200 of a semi-detached quote is scaffolding. Awkward access, conservatories below the eaves or three-storey homes push it higher.
- Replace vs cap. Full replacement strips the old boards so the installer can inspect and treat rafter ends. Capping is cheaper but hides whatever is happening underneath — most specialists now refuse to cap.
- Rot repairs. If rafter feet or wall plates are decayed once the boards come off, expect £30–£60 per rafter end repaired. Budget a 10% contingency.
- Guttering at the same time. New uPVC guttering adds only £8–£15 per metre while the scaffold is up — almost always worth doing together.
- Ventilation. Building Regulations require eaves ventilation to be maintained; over-fascia vents or vented soffit boards add a small amount per metre and prevent condensation in the loft.

Before you commit it helps to understand what happens on site: a full roofline replacement is treated as routine maintenance, so on most homes it is permitted development and needs no planning application – the main exceptions are listed buildings and conservation areas, where swapping timber for uPVC can require consent. Once the old boards are stripped the installer should inspect the rafter feet and wall plates for rot before the new fascias and soffits go on, and Building Regulations require the eaves ventilation path to be kept clear so the loft cannot trap condensation. Renewing the guttering while the scaffold is up is usually the sensible call.
