Fascia and Soffit Replacement Cost UK (2026 Prices)
Fascias and soffits are the boards that run along your roofline — fascias are the vertical facing boards at the roof edge, soffits are the horizontal boards underneath the eaves. They do three jobs: they support the bottom course of tiles, carry the guttering, and close off the roof space from birds, bats and weather. When they rot, your roof edge is exposed and your guttering fails. When they are replaced properly, you get uPVC that will outlast you.
This guide covers 2026 prices by property size, the uPVC versus timber choice, whether to replace guttering at the same time, the overcladding trap, and a scaffold-saving tip that most homeowners miss.
Fascia and Soffit Replacement Costs by Property Type
The dominant cost variable is the perimeter of your roofline, which correlates with property size. These prices include materials, labour, scaffolding and waste removal for a full roofline replacement in white uPVC including guttering.
| Property type | uPVC (full replacement) | Timber (full replacement) |
|---|---|---|
| Mid-terraced house | £1,200 to £2,000 | £2,000 to £3,500 |
| Semi-detached house | £1,500 to £3,500 | £3,000 to £5,000 |
| Detached house | £2,500 to £5,000 | £4,500 to £7,500 |
| Bungalow | £800 to £1,500 | £1,500 to £3,000 |
uPVC is the material used on virtually all new residential roofline work in the UK. Timber is a heritage specification for period properties or conservation area requirements. For any standard residential replacement, uPVC is faster, cheaper, zero-maintenance and equally durable — there is no functional argument for timber unless specifically required by planners.
What the Job Involves
A full roofline replacement follows this sequence:
- Scaffold erected around the roofline — required under health and safety law for work at this height; ladders alone are not compliant
- Existing guttering removed and inspected (or replaced if included in the scope)
- Old fascia boards removed or, if capping rather than full replacement, cleaned and prepared
- Timber behind the fascia inspected for rot — this is the step that sometimes reveals additional work
- Any rotten rafter feet or support timbers replaced before the new boards go on
- New fascia boards fitted and secured to rafter feet
- Soffit boards fitted, including ventilation strips where required
- Barge boards, corner joints and cappings fitted
- New guttering fitted and falls checked
- Scaffold struck and site cleared
Most properties take two to three days from scaffold up to scaffold down. Larger properties or those with significant timber rot can take four to five days.
The Overcladding Trap
Overcladding (also called capping) means fitting new uPVC boards directly over the existing timber fascias rather than removing them. It is cheaper upfront — typically 20 to 30 percent less than full replacement. It is also the source of many roofline failures.
The problem: capping over rotting timber traps moisture between the old and new boards. The rot continues undetected underneath. Within three to eight years, the new uPVC buckles, the fixings fail, or the timber beneath deteriorates to the point where the whole assembly needs replacing anyway — at full replacement cost this time.
The only situation where overcladding is genuinely appropriate is when the existing timber is in sound condition (not rotting, not wet) and the homeowner wants to refresh the appearance at lower cost. A competent roofer will check the condition of the existing timber before recommending overcladding. If they suggest capping without inspection, ask why.
If you are quoted for overcladding and want to verify it is appropriate, push the existing fascia board with your thumb in a few accessible spots. Any softness, spongy areas or visible discolouration mean the timber is already compromised.
Guttering: Replace at the Same Time
If your fascias are due for replacement, doing the guttering simultaneously saves a separate scaffold erection later. The scaffold required for fascia and soffit work provides full access to the guttering anyway — adding guttering replacement to the scope typically costs £300 to £700 extra in materials and half a day of labour, versus £1,200 to £2,000 for a separate gutter replacement job requiring new scaffold.
Gutter profiles and costs:
| Gutter type | Material cost per metre | Best for |
|---|---|---|
| Half-round | £8 to £15 | Standard residential, most common |
| Ogee | £10 to £20 | Period properties, Victorian aesthetic |
| Deep-flow / square | £12 to £22 | Properties with large roof areas |
| Cast iron effect uPVC | £25 to £45 | Conservation areas, heritage properties |
Gutter capacity is often overlooked. Many drainage problems in UK homes are caused by undersized gutters — the gutter is fine, but the cross-sectional area is insufficient for the roof area it serves, particularly in heavy rainfall. If you have had persistent overflow problems, consider specifying deep-flow guttering when replacing. It handles significantly more volume for a marginal cost difference.
Ventilated Soffits: The Building Regulations Requirement
Building Regulations Approved Document F (Ventilation) requires adequate ventilation of the roof space to prevent condensation. The primary route for this ventilation is through the soffit — air enters at the eaves, rises through the loft and exits at ridge vents or other high-level openings.
When replacing soffits, the new boards must maintain this ventilation. This is achieved with:
- Continuous ventilation strip — a strip of ventilation mesh running the full length of the soffit, giving 25mm equivalent free area per metre run. Standard for most new installations.
- Circular vent discs — individual round vents pressed into pre-drilled holes in solid soffit boards. Less effective than continuous strip ventilation but sometimes used for appearance reasons.
If the previous soffit was solid (no ventilation) and your loft has condensation issues, fitting ventilated soffits during replacement directly addresses the problem. Any reputable roofline installer will include appropriate ventilation as standard — if they do not mention it, ask.
Blocking eaves ventilation when adding loft insulation is one of the most common and damaging DIY mistakes. If you are adding insulation at the same time as fascia work, ensure insulation baffles are fitted to maintain the eaves ventilation pathway.
The Scaffold Bundling Opportunity
Scaffold is a significant cost in any roofline job: £500 to £1,500 for a typical house, depending on size and access. If you have any other roofing work that requires scaffold — tile repairs, chimney repointing, flashing work, a Velux window installation — doing it at the same time as fascia and soffit replacement eliminates a separate access cost.
The savings are real. A chimney repointing job that costs £500 in labour might cost £1,000 to £1,200 when a separate scaffold is needed. Bundle it with fascia replacement and you pay only the additional labour — the access is already there.
When getting roofline quotes, tell your roofer about any other known roof issues. A good contractor will identify additional items they can tackle while on the scaffold, and the combined job is nearly always more cost-effective than sequential separate visits. The inspection from the scaffold also catches things you cannot see from the ground.
Frequently asked questions
How much does it cost to replace fascias and soffits on a semi-detached house?
A typical three-bed semi-detached house with uPVC fascias, soffits and guttering costs £1,500 to £3,500 depending on access, condition of existing timber, regional labour rates and whether additional work (barge boards, downpipes, timber repairs) is needed. London and the South East add 15 to 25 percent to these figures. Get three written quotes from NFRC-affiliated roofers or roofline specialists.
How long do uPVC fascias and soffits last?
uPVC fascias and soffits last 20 to 40 years in normal conditions. The material does not rot, does not need painting and resists UV degradation well. The main failure modes are physical impact damage and fading on south-facing elevations over many decades. Unlike timber, uPVC has no ongoing maintenance cost — no painting cycles, no rot treatment.
Can I just repair rather than replace my fascias?
Small sections of timber fascia can be cut out and spliced — a repair for a localised rot pocket. If rot is widespread, or if the existing boards are 20 to 30 years old and showing significant deterioration across multiple sections, full replacement is almost always more cost-effective than repeated targeted repairs. Scaffold is the biggest cost in either case, so paying for it once for a full replacement makes more sense than paying for it twice.
Do I need scaffolding for fascia and soffit replacement?
Yes, for any two-storey property and for most bungalows. UK health and safety regulations require safe working at height, and sustained work on fascias and soffits cannot be done safely from ladders alone. The scaffold also protects public areas below. Most roofline contractors include scaffolding in their quote — confirm this when comparing quotes, as some exclude it.
Should I replace guttering at the same time as fascias?
Yes, almost always. The scaffold required for fascia work covers the guttering at no additional access cost. New guttering in a contrasting or matching colour completes the job visually. If your guttering is more than 15 years old, or if you have had overflow or leak issues, replacement during fascia work is significantly cheaper than a separate guttering job requiring new scaffolding.
