What this calculator estimates

This calculator quotes the all-in replacement price for a residential gutter and downpipe system in 2026 UK pounds, including VAT at 20%. Replacement always includes strip-out, fascia inspection, and almost always drip-tray replacement.

  • Strip-out — labour and skip hire to remove the existing guttering and downpipes. Always included.
  • Fascia repair — new fascia board material and labour where the existing timber has rotted from chronic overflow. The condition selector estimates 0%, 15%, or 40% of the run.
  • Drip tray / kick-out flashing — new lead or aluminium flashing where the old material is bent, rusted, or attached to the old system.
  • Guttering material — per-metre cost of new guttering in your chosen profile (half-round, ogee, square) and material (uPVC, aluminium, galvanised steel, cast iron, copper).
  • Downpipes — material cost based on quantity and run length.
  • Accessories — brackets at 800 mm centres for uPVC or 1,000 mm for metal (BS EN 12056-3 NA), sealant, end caps, angles, hopper heads, swan necks.
  • Install labour — crew hours at the regional rate, with multipliers for profile complexity, building height, and access.
  • Leaf guards — micro-mesh, brush, or hood add-on per metre.
  • Permit / Building Regulations — most replacements don’t require Building Regulations approval, but listed buildings and conservation areas need consent.

A minimum job floor of £680 applies to most UK replacements — the higher floor versus first-fit reflects mobilisation cost of strip-out and skip hire.

How to use it

  1. Measure your linear length in metres. Sum every eave where guttering runs. A 1,200-square-foot semi-detached is typically 42–50 metres; a two-storey detached with bay windows often runs 60–80 metres.
  2. Count corners and angles. Each angle adds 30 minutes and a £6–£14 fitting. Most homes have 4–8 angles; bay-window properties can reach 10–14.
  3. Pick the new profile and material. uPVC half-round is the UK default. Switch to ogee for a more period look, cast iron for matching Victorian or Edwardian heritage, or aluminium for modern architecture.
  4. Set the size. 112 mm half-round is the post-1980s residential default. Bump to 125 mm or 150 mm for steep pitches, large drainage areas, or high-rainfall regions (West Coast, Pennines, Snowdonia).
  5. Specify downpipes. A common rule per BS EN 12056-3 NA: one downpipe per 12 metres of guttering, or one per 75 m² of roof drainage area.
  6. Set fascia condition honestly. “Sound” assumes recent inspection confirmed no rot. “Partial” (15% replaced) is the most common condition on a 15-to-25-year-old system. “Extensive” (40% replaced) is typical when the existing guttering has been overflowing for years.
  7. Toggle drip-tray replacement. Default is on — most replacements swap drip trays concurrently.
  8. Set storey count and access. Three-storey terraces, scaffolded jobs, and back-extension restricted-access properties add 15–25% to labour.

Typical 2026 UK replacement cost ranges

These ranges reflect 2026 UK pricing pulled from Checkatrade, MyBuilder, and NFRC member quotes. Costs include VAT, strip-out, fascia repair on a partial-rot baseline, and new drip-tray work.

Material / profilePer metre replaced50 m typical home
uPVC half-round / square£18 – £32£900 – £1,600
Galvanised steel sectional£28 – £45£1,400 – £2,250
Aluminium half-round (sectional)£35 – £55£1,750 – £2,750

Cast iron ogee£95 – £165£4,750 – £8,250
Copper half-round£110 – £180£5,500 – £9,000

Pricing assumes a two-storey semi-detached, 5 downpipes, partial fascia repair, drip-tray replacement, and standard daytime labour. Single-storey deduct 8–10%. Three-storey terrace or full scaffold add 20–25%. Extensive fascia rot adds another £400–£1,200.

Cost drivers

Fascia repair extent. Biggest variable in replacement projects. Sound fascia means £0 added. Partial rot (15% replaced) typically adds £200–£550. Extensive rot (40%) adds £700–£1,800 — at which point you should also be asking your contractor about soffit and roof-edge sarking, because chronic overflow rarely stays confined to fascia.

Material choice. uPVC is cheapest and lasts 25–35 years before UV degradation in southern UK climates. Aluminium lasts 40+ years with minimal maintenance. Cast iron is the heritage match for pre-1960 properties and lasts indefinitely with periodic repainting (every 8–12 years). Copper is the long-life premium and develops a verdigris patina over 5–15 years.

Listed building or conservation area. Material substitution from cast iron to uPVC is typically not permitted on listed buildings or in conservation areas — confirm with your local planning authority before specifying. Consent applications take 6–8 weeks and add £200–£500 in fees plus drawing prep.

Profile complexity. Half-round is the standard. Ogee and moulded profiles add 15–25%. Box gutters (parapet roofs, terraces) require lead lining and add 30–50%.

Storey height and access. A two-storey roof typically takes 10% longer than single-storey. Three-storey adds 25%. Roofs requiring full tower scaffold rather than ladder access can double access overhead — and tower scaffold hire adds £350–£900.

Strip-out and skip hire. Cast iron is heavy and adds 25–35 minutes per 1.8-metre length to handle and lift down. Skip hire runs £180–£320 for a 4-yard skip; mini-skip £120–£180.

Per-locale code and standards

UK gutter replacement should be designed and installed to:

  • BS EN 12056-3:2000 with UK National Annex — gravity drainage inside buildings, including external rainwater systems sizing.
  • Approved Document C of the Building Regulations — requires roof drainage to discharge into a soakaway, surface water sewer, or watercourse.
  • Approved Document H — drainage and waste disposal connection requirements.
  • BS 6100 — building and civil engineering vocabulary.
  • NFRC Technical Bulletin TB47 — best practice for replacement of rainwater goods on residential properties.
  • CDM 2015 Regulations — apply to any working-at-height project; the contractor must produce a written method statement.

Listed building and conservation area properties require listed building consent before changing material or profile — check with your local planning authority.

Repair vs full replacement decision matrix

Replace the whole system when:

  • Multiple leaks across more than 30% of joints
  • Visible rust through (cast iron) or paint failure (uPVC) across multiple sections
  • Overflow damage has rotted fascia in more than two adjacent rafter bays
  • The system is over 25 years old

Repair (not replace) when:

  • Damage is localised to one or two joints
  • Brackets are sound and fascia is dry
  • Material profile and colour are still readily available from suppliers

Avoiding scams and overcharging

Door-step gutter cleaners pushing replacement work are a recurring UK scam pattern, particularly aimed at older homeowners. Red flags:

  • Unsolicited “I noticed your guttering” doorstep approaches
  • Pressure to sign before you’ve reviewed a written quote
  • Cash-only demands or VAT-exempt offers (legitimate UK contractors charge 20% VAT)
  • No NFRC, FMB, or TrustMark accreditation on materials
  • “Lifetime guarantee” without specifying transferability or company longevity

Insist on a written estimate with material brand, bracket spacing, downpipe count and run length, colour reference (e.g. RAL 7016 anthracite grey), fascia repair line item with per-metre pricing, and a written workmanship warranty (5 years is industry standard for NFRC members).

Frequently asked questions

How much does gutter replacement cost in the UK in 2026?
Most UK homeowners pay £1,200 to £3,800 to replace guttering in 2026, with a typical project landing around £2,400 for 50–55 metres of half-round uPVC on a two-storey semi-detached with six downpipes, partial fascia replacement, drip-tray work, and moderate access. Replacement runs 35–55% more than first-fit installation because of strip-out time, skip hire, and the high probability of fascia or soffit damage discovered after the old guttering comes down. Cast iron or aluminium systems on a Victorian terrace can reach £5,500–£10,000+. Source: 2026 Checkatrade and MyBuilder data plus NFRC member quotes.
Why is gutter replacement more expensive than first-time installation?
Three reasons. First, strip-out and skip hire add 4–6 hours of labour and £40–£90 in disposal. Second, replacement projects routinely uncover hidden fascia and soffit rot — 15–40% of the run typically needs repair before new guttering can mount, adding £250–£1,500. Third, drip trays, leadwork at abutments, and starter brackets are usually replaced concurrently because they're fixed to the old system. Budget 1.4× to 1.6× a first-fit number from a similar property.
Should I just repair instead of replace?
Repair when damage is localised — one or two leaking joints, a few broken brackets, or a single dropped run. Replace the whole system when more than 30% of the joints are leaking, the guttering sags noticeably between brackets indicating widespread bracket failure, you see rust through on cast iron or paint failure on uPVC across multiple sections, fascia damage extends beyond two adjacent rafters, or the system is over 25 years old. Patchwork repairs on a tired system rarely save money — most homeowners replace within 3–5 years anyway.
What's included in a typical UK gutter replacement?
A full replacement bid should include: strip-out and skip removal of existing guttering and downpipes, inspection and replacement of fascia boards and soffit panels where rotted (typically billed per metre), new guttering in your specified material, new downpipes with hopper heads or shoes, brackets at 800 mm centres for uPVC or 1,000 mm for half-round metal (per BS EN 12056-3 NA), end caps and external/internal angles, new drip trays where applicable, sealant at all joints, water butt or splash blocks at ground level, and clean-up. VAT at 20% applies. Always insist on a written line-item proposal — not a single lump sum — and confirm whether the contractor is NFRC accredited.
How long does gutter replacement take?
A typical residential job (50–60 metres, 4–6 downpipes, two-storey semi or terrace, partial fascia repair) takes a 2-person crew 1–2 calendar days. Day one: strip-out, fascia inspection and repair, drip-tray work. Day two: install new guttering, hang downpipes, sealant cure, clean-up. Single-storey bungalows with sound fascia often complete in one long day. Three-storey terraces with full scaffold or extensive fascia rot can run 3–4 days. CDM 2015 applies on any project with a tower scaffold or working at height above 4 metres — confirm your contractor is compliant.
Does buildings insurance cover gutter replacement?
Buildings insurance covers gutter replacement when damage results from a covered peril — storm (typically wind speeds over 55 mph or 88 km/h), falling tree, vehicle impact, fire. Wear-and-tear, age-related failure, rust, and overflow-induced fascia rot are excluded. Document storm damage with photos within 48 hours, notify the insurer within the policy reporting window (typically 30 days), and request a NFRC member's report. Section 49 of the Consumer Rights Act 2015 covers workmanship — you have six years from completion to bring a claim against the contractor for substandard work. Storm-damage claims are routinely scrutinised — review the BS 12056 testing standard with the loss adjuster.
Should I replace the fascia at the same time?
Yes when the fascia shows rot, water staining, or soft spots when probed. Replacing the fascia separately later is twice as expensive because the new guttering has to come back off. Standard practice: strip the old guttering, probe every metre of fascia, replace every section softer than the surrounding wood. Painted timber at £8–£18 per metre installed; uPVC at £15–£28 per metre installed for a 35–50 year service life. The uPVC premium pays back over the next gutter cycle and eliminates repaint cycles.
Should I upsize when I replace?
Consider it if your old guttering overflowed during heavy rain, your roof drainage area exceeds 200 m² per downpipe, you have valleys feeding the run, your roof pitch is above 35° (steep pitches deliver more concentrated flow), or your area has rainfall intensity above 75 mm/hr (5-minute design event per BS EN 12056-3 NA). Going from 112 mm half-round to 125 mm half-round adds about 18% to material cost but 70% to capacity. The retrofit window is now — making the change later requires another strip-out.
Are seamless gutters available in the UK?
Seamless aluminium guttering is offered by several UK suppliers (notably Guttercrest, Lindab, Marley Alutec) and is formed on-site from coil aluminium using a portable brake. The premium versus standard 4-metre lengths is £8–£15 per metre installed. The benefit is the same as in the US market — joints only at corners and outlets, eliminating most leak points. Standard uPVC and cast-iron sectional systems remain the UK default because of installer familiarity and replacement-part availability.
