How Much Does Fascia and Soffit Replacement Cost?
Full fascia and soffit replacement on a typical UK house costs £1,500 to £4,000. Per-metre rates run £60 to £120 for uPVC, more for timber or aluminium. Capping over (covering existing boards rather than replacing) costs roughly half: £800 to £2,000. Scaffolding, where needed, can add £500 to £1,000.
| Property type | Full replacement (uPVC) | Cap-over |
|---|---|---|
| 2-bed terrace | £1,200 to £2,000 | £700 to £1,200 |
| 3-bed semi | £1,800 to £2,800 | £900 to £1,600 |
| 4-bed detached | £2,500 to £4,000 | £1,200 to £2,200 |
| Bungalow (large roofline) | £2,000 to £3,500 | £1,000 to £1,800 |
Full Replacement vs Capping Over: The Decision
This is the most commercially important question in the whole topic, and almost no guide addresses it properly.
| Full replacement | Cap-over (over-cladding) | |
|---|---|---|
| What happens | Old boards stripped back to rafters; new boards fitted | New uPVC boards fixed over the old ones |
| Cost | £1,500 to £4,000 typical | Roughly half of full replacement |
| When it suits | Rotten rafter feet, perished boards, ventilation upgrades needed | Boards structurally sound but weathered; budget priority |
| Watch out | Reveals hidden rot (budget 10% contingency) | Traps existing rot; reduces ventilation if done badly |
Rule of thumb: if a screwdriver pushes easily into the existing timber, replacement is the honest answer. Capping over rot just hides a problem that returns worse in five years.
What Drives the Price?
- Material: uPVC is cheapest and now standard; timber costs more and needs painting; aluminium sits at the top for premium finishes.
- Scaffolding: full scaffold for a detached house can be a third of the bill. Terraces with good access sometimes manage with towers.
- Guttering bundle: replacing gutters at the same time typically adds £400 to £800 but saves a second scaffold hire later.
- Hidden rot: once boards come off, rotten rafter feet or felt need fixing. Keep a 10 percent contingency.
- Region: London and the South East run 20 to 30 percent above the Midlands and North.
Signs Yours Need Replacing
- Flaking paint or visible rot on timber boards
- Sagging or leaking gutters pulling away from the fascia
- Birds or squirrels getting into the loft (gaps at the eaves)
- Damp patches on upstairs walls near the roofline
- Asbestos-cement soffits (pre-1980s): do not disturb; get a survey
Asbestos Warning
Homes built before the 1980s may have asbestos-cement soffit boards. These are safe if undisturbed, but cutting or breaking them releases fibres. Never DIY them: a licensed assessment comes first, and removal adds to the project cost. Mention the property age when getting quotes so contractors price accordingly.
Ventilation Matters
Soffits do a real job: vented soffits let air into the loft, preventing condensation and timber decay. When replacing, specify vented soffit boards (or separate disc vents) to at least current standards. Unvented cap-overs are a common cause of later loft condensation problems.

Fascia and Soffit FAQs
How much does it cost to replace fascias and soffits in the UK?
Typically £1,500 to £4,000 for full uPVC replacement on an average house, or £800 to £2,000 for capping over. Scaffolding can add £500 to £1,000.
Is it better to cap over or replace fascias?
Replace if there is any rot or structural doubt; cap over only when boards are sound and budget is the priority. Capping over rot hides a worsening problem.
How long does fascia and soffit replacement take?
Usually 2 to 4 days for a typical house, plus scaffold erection and removal time.
Do I need scaffolding for fascias and soffits?
Usually yes for safe working at height. Some terraces manage with access towers, but budget for scaffold on detached and semi-detached homes.
Should I replace guttering at the same time?
Almost always yes. It adds £400 to £800 but avoids paying for scaffold access twice, and old gutters rarely survive refixing cleanly.
How long do uPVC fascias last?
20 to 30 years with minimal maintenance. Timber lasts 10 to 15 years even with regular painting.
Do fascias need planning permission?
No, like-for-like replacement is permitted development. Listed buildings need consent for material changes.
What are soffits for?
They close the gap under the eaves and, when vented, ventilate the loft space to prevent condensation and timber rot.
