Fascias, soffits and guttering: costs and what to look for (2026 UK)
Nobody gets excited about the roofline. It is also, pound for pound, one of the most consequential parts of your house: it carries rainwater away from the walls and it ventilates the roof void. When it fails, the damage shows up as damp walls, rotten roof timbers and ruined insulation — repairs that cost several times what the roofline itself would have. Here is what replacement genuinely costs in 2026 and how to tell a good job from a cheap one.
- Typical semi, full uPVC replacement: £1,800–£3,500
- Guttering only: £400–£900
- Vented soffits are not optional — check the spec

What each part actually does
Quotes get much easier to read once you know which component is which.
- Fascia: the board fixed to the ends of the rafters along the eaves. It closes off the roof edge, supports the bottom row of tiles or slates, and carries the gutter brackets. It does real structural work — a soft fascia will not hold a full gutter.
- Soffit: the horizontal board tucked underneath the fascia, spanning back to the wall. It closes the eaves against birds and weather and, critically, is where roof ventilation enters.
- Bargeboard: the same idea as a fascia but running up the sloping gable edge.
- Guttering and downpipes: collect the water off the roof and take it to the drain. Half-round and square profiles are the common domestic options.
2026 replacement costs
The figures below are typical UK installed prices including scaffolding or access equipment, removal and disposal of the old materials, and VAT-registered contractor labour.
| Job | Typical 2026 cost | Notes |
|---|---|---|
| Mid-terrace, full uPVC roofline | £1,400 – £2,600 | Front and rear only; no gable |
| Three-bed semi, full uPVC roofline | £1,800 – £3,500 | The most common job by far |
| Detached house, full uPVC roofline | £3,000 – £6,000 | More runs, more gables, more scaffold |
| Fascia and soffit, per linear metre | £50 – £90 | Full replacement including labour |
| Capping over sound timber, per metre | £35 – £55 | Cheaper, but see the warning below |
| uPVC guttering, per metre | £15 – £30 | Plus fittings, brackets and downpipes |
| Aluminium or cast iron guttering, per metre | £60 – £120 | Period properties; far longer life |
| Scaffolding | £600 – £1,200 | Sometimes included, often not — check |
Two things move these numbers more than anything else: access and gables. A three-storey town house or a property with restricted rear access can add £500 or more in scaffold alone, and every gable adds bargeboard runs at height.
Capping versus full replacement
Capping — sometimes sold as overcladding or overboarding — means bonding a new uPVC cover board over the existing timber fascia rather than stripping it out. It is quicker, needs less disposal, and typically saves 30 to 40 percent.
It is a perfectly legitimate method when the timber underneath is sound. The problem is that it is often sold when it is not. Sealing a uPVC skin over damp or rotting timber traps the moisture, the decay carries on invisibly, and the gutter brackets end up screwed into something that cannot hold them. Five years later the whole lot needs doing properly anyway.
The question that protects you
Ask the installer to show you the condition of the existing timber before agreeing to capping, and get the method — cap or full replacement — written explicitly into the quote. A contractor confident in the timber will have no problem doing either.
Materials compared
- uPVC: the default for good reason. Around 20–30 years of life, no painting, wide colour and woodgrain range, and the cheapest option installed. Cheaper grades can discolour or go brittle, so ask what thickness and grade is being used.
- Aluminium: more expensive up front but very long-lived, dimensionally stable and excellent in coastal or exposed locations. Powder-coated finishes hold colour extremely well.
- Cast iron: the right answer on period and listed properties, and often required in conservation areas. Heavy, expensive, needs periodic painting, but lasts generations.
- Timber: authentic and repairable, and sometimes the only option a conservation officer will accept. Budget for repainting every four to six years.
The ventilation detail most quotes leave out
A pitched roof void needs continuous airflow at the eaves. Without it, warm moist air from the house condenses on the cold underside of the roof, soaking the insulation and, over years, rotting the timbers. Because the soffit is the gateway for that airflow, replacing it with a solid, unvented board is a genuine defect — and it is one of the most common shortcuts on a cheap roofline job.
A proper specification includes either a continuous vent strip along the soffit or a regular pattern of vent discs, and keeps the airway inside the eaves clear of insulation. If a quote does not mention ventilation at all, ask before you sign.
Warning signs it is time to replace
- Gutters that sag, or that overflow in heavy rain despite being clear
- Dark vertical staining or green algae running down the external wall
- Damp patches on internal walls close to the ceiling
- Flaking paint, soft spots or visible rot on timber fascias
- Birds, wasps or squirrels getting in behind the soffit
- Gutter joints that have been repeatedly sealed with mastic
None of these are cosmetic. Each one means rainwater is reaching somewhere it should not.
Getting a fair quote
Roofline work is a common target for high-pressure doorstep selling, usually featuring a large discount that expires today. Treat that as a reason to walk away. Get three written quotes, make sure each one states the same scope — full replacement or capping, whether guttering is included, whether scaffolding is included, and what ventilation is being provided — and check the contractor is registered with a recognised body such as NFRC or TrustMark. Compare the specifications, not just the totals. You can also browse our roofing cost guides for wider context.
FAQs: fascias, soffits and guttering (UK, 2026)
How much does it cost to replace fascias, soffits and guttering in 2026?
For a typical three-bedroom semi-detached house expect £1,800–£3,500 for full replacement in uPVC, including scaffolding and removal of the old materials. A mid-terrace is often £1,400–£2,600 and a detached house £3,000–£6,000. Guttering on its own is usually £400–£900.
Is capping over old fascias a good idea?
Only if the timber underneath is genuinely sound. Capping bonds a uPVC cover board over the existing fascia and saves roughly 30–40 percent, but if there is any rot it seals moisture in and the decay continues out of sight. Insist the installer shows you the condition of the timber before agreeing to cap.
How long do uPVC fascias and soffits last?
Good quality uPVC fascias and soffits typically last 20–30 years and need no painting. Aluminium lasts longer still and holds colour well. Timber remains the right choice on listed and period properties but needs repainting every four to six years.
Do soffits need ventilation?
Yes, in almost all cases. Pitched roofs rely on airflow at the eaves to remove moisture from the roof void, and blocking it causes condensation, damp insulation and eventually rot in the roof timbers. Replacement soffits should include continuous vent strips or vent discs. Solid unvented soffits are one of the most common defects on cheap installations.
How do I know when fascias and guttering need replacing?
Look for gutters that sag or overflow in heavy rain, dark staining running down the external walls, damp patches on internal walls near the ceiling, flaking paint or soft spots on timber fascias, and birds or wasps getting in behind the soffit. Any of these means water is no longer being taken away from the building properly.
