What this calculator estimates

This calculator quotes the all-in installed price for full soffit and fascia replacement on a typical UK property in 2026 GBP. It separates the bill into the line items real UK eaves contractors invoice:

  • Soffit boards — the horizontal under-eave covering, sold per linear metre of eave run.
  • Fascia board — the vertical board behind the gutter (or bargeboard at the gable verge), sold per linear metre.
  • Strip-off — removal and disposal of existing soffit and fascia.
  • Paint or factory finish — on softwood timber requiring field-painting.
  • Over-fascia ventilation strip — continuous 10 mm gap meeting Approved Document F / BS 5250 intake ventilation.
  • External corners — pre-formed corner sections (typically 4 on a simple semi, 6 to 10 on detached homes with bay returns).

A minimum call-out floor of £280 applies on most UK installations. Small jobs under 12 linear metres often hit the floor because scaffold or tower hire plus mobilisation dominates small-job cost.

How to use it

  1. Soffit linear metres — total eave run where soffit meets the outer wall. Typical UK 3-bed semi: 30 to 40 m. Detached: 40 to 60 m.
  2. Fascia linear metres — usually equal to soffit run. Add bargeboards if you want gable verges wrapped at the same time.
  3. Material — uPVC (cheapest and most common), aluminium powder-coated, painted softwood, fibre-cement (Cembrit, Eternit), or composite cellular PVC / HPL.
  4. Property height — single-storey (bungalow), two-storey (standard semi or terrace), or three-storey or higher.
  5. Site access — easy (open garden, no obstructions), moderate (standard suburban setback), or difficult (overhead lines, narrow back garden, scaffold required).
  6. Strip-off — toggle ON for any replacement job (rare to leave existing timber in place).
  7. Paint or factory finish — toggle ON for softwood timber requiring painting. uPVC, aluminium, fibre-cement, and composite arrive factory-finished.
  8. Over-fascia vent strip — toggle ON to add continuous intake ventilation (Building Regs Approved Document F requirement on most modern roof renewals).
  9. External corners — count the corners where soffit and fascia turn 90 degrees. Simple semi: 4. Detached with bay: 6 to 10.

Cost drivers

Material. uPVC is the cheapest and most common UK choice at around £6 to £10 per linear metre delivered, but aluminium is the durable alternative at around £8 to £14 per metre delivered and 15 to 20 percent more installed. Softwood is similarly priced to uPVC but adds an 8- to 12-year paint cycle that lifts whole-life cost. Fibre-cement (Cembrit Patina, Eternit) is more durable than softwood and visually closer to traditional painted timber, but adds 30 to 50 percent to installed cost because of weight, slower cutting, and HSE-mandated silica dust controls.

Property height. Bungalows are the baseline. Two-storey adds 15 percent for ladder repositioning. Three-storey or higher adds 30 to 40 percent because of larger ladders, scaffold or tower hire, and the slower pace working at height (Work at Height Regs 2005). Tower hire runs £180 to £280 per week and gets billed through.

Site access. Open front garden with no obstructions is easy. Suburban detached gardens with mature planting are moderate. Tight terraced rear access via shared alleys, parked-car obstruction, or overhead BT and electricity lines under 3 m clearance can add 20 to 40 percent — sometimes requiring DNO de-energisation request 21 days in advance.

Strip-off condition. Sound softwood being replaced for cosmetics is easy strip-off. Rotted softwood with active wet-rot reveals damaged rafter feet underneath, which adds carpentry time at £35 to £55 per hour. Pre-1985 asbestos-cement soffit requires licensed asbestos abatement under the Control of Asbestos Regulations 2012 — that alone can triple the strip-off line. Always include a 10 to 15 percent contingency for rot or asbestos discovery on properties over 30 years old.

Vent strip and corner count. A 10-corner detached with bay returns costs £400 to £800 more in corner returns than a 4-corner semi. Continuous over-fascia vent strip adds £12 to £15 per linear metre but is non-negotiable on most modern re-roof warranties under BS 5534 / 5250.

When to replace soffit and fascia

Visible rot or peeling paint. Once paint starts peeling and the softwood below feels soft to a screwdriver probe, you have under 12 months before fascia loses gutter-screw fixings. Replace at first sign.

Re-roof timing. Always check soffit and fascia before signing a new roof contract. The cheapest moment to replace is during the re-roof while the gutters are off and scaffold is on site. Adding it after the fact often costs 25 to 40 percent more.

Gutter replacement timing. New uPVC or aluminium gutter brackets mounted on rotted softwood pull out within 2 to 3 years. Replace fascia at the same time as gutters or beforehand.

Pest entry. Squirrels, jackdaws, starlings, and bats enter lofts through gaps in soffit and rotted fascia corners. Note that bats are protected under the Wildlife and Countryside Act 1981 — if you find bat evidence (droppings, urine staining), stop and call your local Bat Conservation Trust before proceeding.

Storm damage. UK winter named-storm wind gusts above 70 mph (Storm Arwen, Eunice, and others in recent seasons) commonly peel aluminium or uPVC soffit panels off lower edges. Document with photos within 72 hours for the insurance claim.

What to look for in a UK contractor

A competent UK eaves contractor will:

  1. Survey on-site with a fascia probe, not from a photo or aerial estimate.
  2. Inspect rafter feet and wall-plate for rot before quoting.
  3. Quote line-by-line: soffit material, fascia material, strip-off, over-fascia vent strip, corners, paint, scaffold or tower hire.
  4. Provide manufacturer specification with BBA Agrément certificate for the soffit product (most reputable uPVC brands have BBA).
  5. Carry public liability of at least £2 million and employer’s liability under the Employer’s Liability Act 1969.
  6. Belong to NFRC, the National Federation of Roofing Contractors, or hold Competent Person Scheme status under Building Regulations.
  7. Offer a written workmanship warranty of 5 to 10 years plus the manufacturer’s product warranty (typically 10 years on uPVC, 25 years on aluminium, lifetime on fibre-cement).

Red flags: refusal to inspect rafter feet, quotes that exclude scaffold or tower hire, cash-only requests, and unsolicited door-to-door cold callers offering “today only” pricing after a storm.

Diagnostic checklist before quoting

Before signing a contract, walk the perimeter with the contractor and tick:

  • Soft spots or sponginess in softwood fascia (probe with a screwdriver — should be firm).
  • Paint peeling, blistering, or fading more than 30 percent.
  • Visible nail-head rust staining running down fascia.
  • Gutter joints leaking or brackets pulled loose.
  • Daylight visible from inside the loft at the eave line.
  • Bird, squirrel, or bat entry in soffit corners (NB: bats are protected).
  • Bare softwood exposed where uPVC or aluminium has detached.
  • Asbestos suspicion on pre-1985 fibre-cement soffit (test before disturbing).

Frequently asked questions

How much does it cost to replace soffit and fascia in the UK in 2026?
Most UK homeowners pay £1,400 to £4,200 to replace 36 linear metres of soffit and 36 linear metres of fascia on an average semi-detached house in 2026 — roughly £25 to £55 per linear metre installed for uPVC or aluminium, £35 to £75 per linear metre for fibre-cement or composite, and £40 to £85 per linear metre for painted softwood. Two-storey homes add 15 percent. Three-storey or higher adds 35 percent. Stripping existing rotted timber adds £6 to £8 per linear metre. A continuous over-fascia vent strip adds £12 to £15 per linear metre. External corners cost £85 to £110 each in pre-formed material.

What is the difference between soffit and fascia in UK construction?
The fascia is the long vertical board running along the lower edge of the roof — it covers the rafter feet and supports the rainwater gutter. The soffit is the horizontal board under the eave, closing off the space between the fascia and the outer wall. On UK gable roofs, the equivalent boards at the gable end are called bargeboards. Together fascia, soffit, and bargeboards form the eaves and verge details — a complete BS 5534 compliant roof requires all three to be in sound condition for the roof covering warranty to remain valid.
Should I replace fascia at the same time as new gutters?
Yes, almost always. New uPVC or aluminium gutters fitted to rotted softwood fascia will sag within 18 to 36 months as the screw fixings tear out of softening timber. The combined replacement on a 36 m perimeter typically costs £2,800 to £4,500 versus £2,200 fascia-only plus £1,400 gutters-only sequentially — about 25 percent saved by combining the mobilisation. Always inspect the timber behind the existing gutter before quoting a gutter-only replacement; you will find rot at the joint fixings on any south-facing softwood fascia over 12 years old.
What is over-fascia ventilation and is it required?
Over-fascia ventilation is a continuous strip with a 10 mm air gap fitted at the top of the fascia and under the eave course tile, providing the BS 5250 and Approved Document F intake ventilation for the loft space. A 10 mm continuous strip provides about 10,000 mm² per linear metre of NFVA. UK Building Regulations require 25,000 mm² total intake on pitched roofs over 15 degrees, balanced with high-level (ridge) ventilation. Over-fascia is the modern standard; older properties may rely on soffit-vent discs (one disc per metre, less effective). Without adequate ventilation the loft picks up moisture and roof timbers grow mould, voiding most modern tile warranties.
uPVC or aluminium soffit and fascia — which is better for UK weather?
uPVC dominates UK installations — it is cheaper, lighter, never needs painting, and stands up to UK damp climate without rot. Lifespan 20 to 30 years, after which it yellows on south-facing elevations. Aluminium powder-coated is the durable upmarket choice — 30 to 50 year service life, holds colour better, will not crack in frost, and is fire-resistant. Aluminium costs about 15 percent more than uPVC installed. For coastal or exposed sites (Cornwall, Western Isles, exposed Pennines), aluminium with marine-grade fasteners outperforms uPVC. For sheltered suburban properties, uPVC is the value choice.
Can I install soffit and fascia myself?
Single-storey installation by a competent DIYer is realistic and saves around 50 to 60 percent on labour. You need a 4 m or 5 m ladder with stand-off, an electric saw with a fine-tooth blade for uPVC, and a basic working-at-height risk assessment under the Work at Height Regulations 2005. Two-storey or higher work should be left to insured contractors — most insurer-recognised installers carry scaffold or tower hire on top of their day rate. Never DIY a fascia replacement that involves cutting back rotted rafter feet; that becomes structural carpentry under Building Regulations Approved Document A.
How long should uPVC soffit and fascia last in the UK?
Good-quality uPVC (Eurocell, Swish, Freefoam): 20 to 30 years, with gradual yellowing on south-facing runs from year 15 onward. Aluminium powder-coated: 30 to 50 years, colour holds throughout. Painted softwood: 8 to 12 years between paint cycles, 25 to 40 year total service with diligent repainting. Fibre-cement (Cembrit, Eternit): 30 to 50 years, paint cycle every 12 to 15 years. Composite cellular PVC or HPL (Rockpanel, Trespa): 40 to 60 years with virtually no maintenance — top of market upfront, lowest whole-life cost. Failure mode is almost always softwood rot at the rafter-foot interface, UV embrittlement on uPVC, or storm damage on aluminium clips.
Do I need scaffold for a fascia replacement?
On a two-storey property, most NFRC member contractors will price a tower scaffold or fixed scaffold rather than relying on ladders alone — the Work at Height Regulations 2005 require fall protection above 2 m where reasonably practicable. Tower scaffold hire runs £180 to £280 per week and is the most common choice. Fixed scaffold on a semi-detached property typically costs £450 to £750 erected for a week. Always check that scaffold is included in the fascia quote — some contractors quote ladder-only and add scaffold at extra cost mid-job. For three-storey or higher, scaffold is non-negotiable.
