What this calculator does

This is a material-comparison gutter cost calculator for the UK market. Enter your home’s linear gutter length and downpipe count once, and the calculator prices every realistic UK gutter material on the same job. You see DIY material-only cost, full installer cost, and projected ownership cost over your chosen horizon — typically 30 years.

That last column is what most homeowners miss. PVC is cheapest upfront but you’ll replace it twice in 30 years. Cast aluminium costs more upfront but you’ll fit it once and never think about it again. Annualised over the ownership horizon, the cheapest upfront material rarely wins.

How to use it

  1. Measure your linear length in metres. Walk the perimeter of your home with a tape. A 1930s 3-bed semi typically runs 28 to 38 metres. A 4-bed detached with bay windows runs 45 to 65 metres. Sum every eave where guttering will run.
  2. Set your downpipe count. UK rule of thumb (per BS EN 12056-3): one 68 mm downpipe per 12 to 16 metres of half-round gutter. Most semi-detached homes need 2 to 3; detached homes 3 to 5.
  3. Set the average downpipe length. Single-storey eave to gully is 3 to 4 metres. Two-storey is 6 to 8 metres.
  4. Set your ownership horizon. 30 years is the standard residential default.

The output table ranks materials cheapest-to-most-expensive on full installed cost. The two header cards highlight the cheapest installer fit and the best long-term value (lowest annualised cost). These are usually different materials.

MaterialMaterial £/mInstalled £/mService life
PVC sectional half-round (Floplast / Marshall-Tufflex)£6£18 – £3012–15 yr
Galvanised steel£14£25 – £4022–28 yr
Cast aluminium ogee / deepflow (Alumasc / Alutec)£24£40 – £7535–45 yr

Zinc (VMZINC / Rheinzink)£37£75 – £12070–80 yr
Copper (KME / Aurubis)£58£85 – £14090+ yr

Pricing assumes a single-storey home, 3 downpipes, easy ladder access, and standard daytime labour. Two-storey adds 10 to 15%. Difficult access (no rear lane, scaffold required) adds 20%.

Why annualised cost matters

A common UK mistake is to fit cheap PVC, replace it at year 12, fit it again, replace it at year 24, and call it a day at 30 years. The reality is that you’ve paid the full installer cost three times — including scaffold hire each time.

Worked example, 45 m semi-detached, 30-year horizon:

  • PVC sectional installer-fit = £900 × 3 replacements = £2,700 over 30 years = £90/year
  • Cast aluminium ogee = £2,200 × 1 replacement = £2,200 = £73/year
  • Cast iron heritage = £4,000 × 1 replacement (60-year life clears 30) = £4,000 = £133/year (but a single 50-year horizon flips the picture)
  • Seamless aluminium = £1,800 × 1 replacement = £1,800 = £60/year

Cast aluminium is the annualised winner for most non-listed properties on a 30-year view. PVC wins only for very short ownership horizons (5 to 10 years) where you won’t see the second install.

What drives UK cost

Profile. Half-round is the UK residential default and is the priced baseline. Ogee and deepflow profiles cost 15 to 30% more because they’re injection-moulded or cast, not extruded. Square-line PVC is roughly 5 to 10% above standard half-round.

Brand and gauge. PVC ranges from £4 per metre (own-brand DIY-shed) to £8 per metre (Floplast Hi-Cap with 10-year guarantee). Cast aluminium ranges from £18 (Alutec) to £35 (Alumasc Heritage) per metre. The premium buys impact resistance, colour fastness, BBA Agrément certification, and longer manufacturer warranty.

Storey and access. Two-storey adds 10 to 15% to labour because of ladder repositioning. Three-storey or above-shop adds 25%. Tower scaffold hire is £80 to £200 per week if extension-ladder access isn’t safe per Working at Height Regulations 2005.

Tear-off. Removal of existing PVC adds about £4 per metre and £40 to £60 dump fee. Removal of cast iron is more involved (heavy lifting, sometimes leaded joints) and adds £8 to £15 per metre.

Listed and conservation. Listed Building Consent requires like-for-like material match, ABF (Architects’ Buildings Forum) consultation in some boroughs, and may require specific suppliers. Add 20 to 35% to total project cost.

Region. London and South East run 15 to 25% above the median. Scotland, the North East, and rural Wales run 10 to 20% below.

DIY vs installer decision matrix

DIY makes sense when:

  • The home is single-storey or accessible bungalow
  • You’re using PVC or galvanised steel sectional
  • You have a Class 1 ladder and a helper
  • The total length is under 30 metres
  • The work is non-listed and not in a conservation area

Hire an installer when:

  • The home is two or three storey
  • You want cast aluminium, cast iron, zinc, copper, or seamless aluminium
  • The job is over 35 metres
  • The property is listed or in a conservation area
  • You want a workmanship warranty (FMB, NFRC, Checkatrade-vetted)

A UK installer charges £14 to £25 per metre in labour above material cost. That premium buys public liability insurance (£2 m minimum), Working at Height Regulations 2005 compliance, BS EN 12056-3 sizing per actual rainfall data, BBA Agrément-certified products, and a written workmanship warranty (5 years industry standard, 10 years for FMB members under the Master Build Guarantee).

UK codes and standards

UK guttering work is governed by:

  • BS EN 12056-3:2000 — Gravity drainage systems inside buildings, Part 3: Roof drainage, layout and calculation. Sets gutter sizing tables for UK rainfall intensities.
  • BS EN 1462:2004 — Brackets for eaves gutters, requirements and testing.
  • Approved Document C — Site preparation and resistance to contaminants and moisture.
  • Approved Document H — Drainage and waste disposal.
  • Working at Height Regulations 2005 — Mandatory risk assessment for any work above 2 m.
  • BBA Agrément Certificate — Voluntary third-party product approval; required for some new-build warranty schemes.
  • NHBC Standards — For new-build, gutter and downpipe sizing must match Building Regulations Part H and NHBC Chapter 7.2.

Listed buildings additionally require Listed Building Consent under the Planning (Listed Buildings and Conservation Areas) Act 1990. Conservation areas may have Article 4 Direction restrictions.

Maintenance affects total cost

Annual cleaning by a Checkatrade-vetted contractor (£80 to £180 for a typical semi) extends gutter material life by 25 to 40%. PVC neglected for 5+ years may fail at year 8 instead of year 14 because chronic overflow rots the fascia and pulls bracket fixings. Cast iron requires repainting on a 7 to 10-year cycle to prevent rust-through; budget £6 to £12 per metre for a proper sand-blast and zinc-rich primer plus topcoat.

Avoiding cowboy installers

Red flags:

  • No FMB, NFRC, Checkatrade, or TrustMark accreditation
  • Cash-only or “mate’s rates” without VAT receipt
  • Pressure to sign on the day after a doorstep approach
  • “Storm damage” claims after a normal weather event
  • Quotes 30%+ below others (often signals own-brand PVC, sectional rather than seamless, or unregistered labour)
  • No public liability certificate produced on request

Insist on a written quote listing the manufacturer (Floplast, Marshall-Tufflex, Alumasc, Hargreaves, Lindab, KME), profile and gauge, bracket spacing per BBA / BS EN 1462, downpipe count and run length, colour, and workmanship warranty length.

Frequently asked questions

How much does new guttering cost in 2026?
The 2026 UK median is £680 to £1,580 for 45 metres (about 150 ft) of PVC half-round professionally fitted on a single-storey home with four downpipes. Cast aluminium runs £1,200 to £2,400 for the same job. Heritage cast iron lands at £2,800 to £5,500. Per-metre installed pricing is the cleanest comparator — PVC at £18 to £30 per metre, cast aluminium at £40 to £75, copper at £85 to £140. Sources: 2026 Checkatrade and MyBuilder cost guides plus quotes from NFRC member contractors.
What's the cheapest guttering material per metre?
PVC half-round (Floplast or Marshall-Tufflex) is cheapest at £6 per metre material cost, £18 to £30 per metre installed. It is the only realistic DIY option for a UK homeowner with no specialty tools. Service life is 12 to 15 years. Galvanised steel sectional at £14 per metre material is the next step up. Cast aluminium half-round (Alumasc, Alutec, Hargreaves) at £24 per metre material is the heritage-look upgrade with 40-year service life.
Is cast iron guttering worth the cost in 2026?
Yes for listed buildings, conservation areas, and pre-1920 properties where the planning officer or Listed Building Consent specifies cast iron. Cast iron at £30 to £45 per metre material (£70 to £120 installed) is 5 to 8 times PVC upfront but lasts 60+ years if painted on a 7- to 10-year cycle. For non-conservation properties, cast aluminium offers the same heritage profile (ogee, deepflow, victorian) at half the cost and one-third the weight, with 40-year life and no painting requirement. The annualised cost of cast aluminium typically wins.
Can I fit guttering myself?
Yes for PVC and galvanised steel sectional. Plumbing and DIY chains stock 4 m lengths with running outlets, stop ends, internal and external angles, and downpipe brackets. Plan on a full weekend for a 45 m job, plus £80 to £150 for a tower scaffold or extension ladder hire. Cast iron, zinc, copper, and seamless cast aluminium are not realistic DIY — cast iron sections weigh 8 to 12 kg per metre, copper requires soldering, and zinc requires sheet-metal experience. Working at Height Regulations 2005 require a risk assessment for any work above 2 m.
How long do PVC gutters last?
PVC sectional from a major brand (Floplast Hi-Cap, Marshall-Tufflex Plus, Brett Martin Roundstyle) lasts 12 to 15 years before UV-induced brittleness causes hairline fractures at bracket points. The failure mode is rarely catastrophic — usually a slow drip from a single joint. Older mid-1980s PVC fitted before BBA Agrément Certificate requirements often fails earlier. The 12-year typical life is on the low end of the European average because UK winter weather is wet rather than freeze-thaw severe, but UV exposure on south-facing eaves can shorten it.
Do I need planning permission for new guttering?
No, for like-for-like replacement on most properties. New guttering counts as repair and falls within Permitted Development Rights under the General Permitted Development Order. Exceptions: listed buildings (full Listed Building Consent required even for like-for-like repair), conservation areas (Article 4 Direction may apply), and changes from existing material (e.g. PVC to cast iron on a non-listed building may still need planning). Always confirm with your local planning department before changing materials on any property over 60 years old.
What size gutter do I need?
BS EN 12056-3:2000 sets the formal sizing tables. Rule of thumb for UK rainfall (75 mm/h design intensity): 100 mm half-round handles up to 40 m² of roof drainage area per outlet; 115 mm handles up to 65 m²; 125 mm Hi-Cap handles up to 90 m². For most semi-detached and terraced homes, 112 mm or 115 mm half-round is correct. Detached homes with steep roofs and large catchment can need 125 mm Hi-Cap or square line. The calculator's downspout count input lets you match BS EN 12056-3's outlet capacity calculations.
How does cost vary by region?
London and the South East run 15 to 25% above the national median because of higher labour rates and parking restrictions affecting site logistics. Scotland, the North East, and rural Wales run 10 to 20% below. Northern Ireland sits roughly with the North West. Listed buildings, conservation areas, and properties with restricted access (mews, terraces with no rear access) add a further 15 to 30% regardless of region. The calculator's per-foot labour rate approximates the UK national median; scale inputs up or down for your specific area.
