Fascias & Soffits Cost UK 2026: Replacement by House Size + Material

UK fascia + soffit replacement Q2 2026: terraced £1,200-2,200, semi-detached £2,000-3,500, detached £3,000-6,000, bungalow £2,200-4,000 — including uPVC fascias, ventilated soffits + scaffolding. Per metre, full uPVC replacement is £40-70/m. Adding new gutters at the same time adds £300-1,500 but saves on shared scaffolding. London/SE +20-30%.

Full replacement (£40-70/m) removes the old timber + fits new uPVC — the right choice if the existing timber shows any rot, damage or movement. Capping over (£25-45/m) clads new uPVC over sound existing timber — cheaper + quicker, but only safe if the timber behind is genuinely sound + dry. The risk with capping is that hidden rot continues behind the new uPVC + spreads to the roof structure. A reputable installer will inspect the timber + only recommend capping where it's truly sound. When in doubt, replace.

Usually yes for a two-storey house — fascias + soffits sit at roof-eaves height + safe access is essential. Scaffolding adds £500-1,200 to the job depending on height + access. Some installers use scaffold towers or access platforms for simpler single-storey + bungalow rooflines, which is cheaper. Because the scaffolding is a fixed cost regardless of how much roofline work you do, it's the most economical time to also replace gutters + downpipes — you only pay for access once.

Quality uPVC fascias + soffits last 25-30 years with virtually no maintenance — just an occasional wash. They don't rot, warp or need repainting (unlike timber, which needs repainting every 5-7 years). Aluminium roofline lasts even longer (30-45 years) but costs more. Most uPVC roofline comes with a 10-year manufacturer guarantee. The main failure point isn't the uPVC itself but poor fitting — inadequate fixings or missing ventilation — so use an experienced roofline specialist.

Ventilated soffits allow air to flow into the roof space, which is required to meet roof-ventilation standards + prevent condensation building up in the loft. Without adequate ventilation, warm moist air condenses on the cold roof timbers, leading to damp, mould + eventually timber rot. Modern uPVC soffits include ventilation strips (or are paired with over-fascia vents) to provide this airflow. When replacing roofline, always confirm ventilated soffits are included — a sealed, unventilated roofline is a common cause of loft condensation problems.
