Guttering Repair & Replacement Cost UK (2026 Guide)

Guttering rarely gets attention until it fails. A blocked downpipe, a split joint or a section pulled away from the fascia by the weight of debris — all of these can lead to water running down external walls, seeping into cavity walls or pooling around foundations. Left unaddressed, what starts as a simple guttering repair can turn into a much more expensive damp problem inside the home.

This guide covers the typical cost of guttering repairs and full replacement in the UK for 2026.

Guttering Repair & Replacement Cost: Quick Summary

Prices vary depending on the property size, number of storeys and accessibility. London and South East prices typically run 20–30% higher.

Types of Guttering in the UK

UPVC Guttering

The vast majority of UK homes built since the 1970s have UPVC guttering. It's inexpensive, widely available, resistant to rust and easy to work with. The main drawbacks are a shorter lifespan than cast iron (typically 20–30 years vs 50–100 years) and a less attractive appearance on older or period properties.

A full UPVC guttering replacement on a standard three-bedroom semi-detached home typically costs £600–£1,200, depending on the size of the property and how much downpipe work is involved.

Cast Iron Guttering

Cast iron guttering is the original choice for Victorian, Edwardian and other period properties. It's heavy, durable and — when properly maintained — essentially lasts indefinitely. The downsides are higher cost, the need for periodic repainting and the risk of cracking if sections are knocked or not supported properly.

Replacing cast iron guttering costs significantly more than UPVC — expect £1,500–£3,500 for a full replacement on an average property, depending on the profile required and the complexity of the installation.

Aluminium Guttering

Aluminium offers a middle ground: lighter than cast iron but more attractive and durable than UPVC. Powder-coated aluminium guttering can be fabricated on-site in continuous lengths, eliminating joints (and therefore potential leak points). It's a popular choice for self-builders and high-specification renovation projects.

Costs run from £800–£2,000 for a full replacement.

What Affects Guttering Costs?

Property height — Single-storey guttering can often be reached from a ladder. Two-storey and above requires scaffolding or a tower, adding £200–£500 to the job.

Length of run — Guttering costs are largely priced per linear metre for materials, plus labour. Larger or more complex roof profiles with multiple valleys, hips or returns need more guttering.

Condition of fascia boards — Guttering clips and brackets fix to the fascia. If the fascia is rotten or damaged (common on older properties), it will need replacing at the same time, adding to the overall cost. See our guide to fascia and soffit replacement costs.

Existing material — Removing and disposing of cast iron guttering takes more time than UPVC, adding to labour costs.

Number of downpipes — More downpipes mean more work. An average three-bed semi might have two downpipes; larger or detached properties may have four or more.

Do I Need to Replace All the Guttering, or Just Repair It?

In many cases, a targeted repair — resealing a joint, replacing a cracked section or re-fixing a bracket — is perfectly adequate. If the guttering is relatively recent and in otherwise good condition, repair makes economic sense.

Signs that full replacement is worth considering:

• Multiple leaking joints across the whole run
• Guttering that is badly discoloured, cracked or brittle
• A system that is over 25–30 years old
• Fascia boards that need replacing anyway (making the guttering easier to renew at the same time)

Can I Clean and Repair Guttering Myself?

Guttering cleaning is one of the more accessible DIY jobs provided you're comfortable working at height with a stable ladder. For single-storey buildings, most homeowners can clear gutters themselves. For two-storey or above, the risks increase significantly and professional cleaning is advisable.

Resealing a leaking joint is also within reach of a capable DIYer — specialist gutter sealant is available for a few pounds at any builders' merchant. However, anything involving replacing sections, adjusting falls or working on fascia boards is best left to a professional.

Finding a Reliable Guttering Contractor

Guttering work is often carried out by the same tradespeople who do fascia, soffit and roofing work. When getting quotes:

• Insist on at least two or three written quotes
• Check whether the price includes disposal of the old guttering
• Ask specifically whether the fascia boards need attention before the new guttering is installed
• Look for membership of the NFRC or similar trade body for contractors also doing roofing work

FAQ

How often should guttering be cleaned? Twice a year is a sensible rule of thumb — once in late spring after any blossom fall, and once in late autumn after the leaves have come down. Properties surrounded by trees may need more frequent attention.

Why is my guttering overflowing when it's not blocked? Overflowing guttering that isn't blocked usually indicates either that the fall (the slight angle that directs water towards the downpipe) has been lost, or that the guttering is too small for the roof area it serves. A roofer or guttering specialist can assess this.

How long does guttering last? UPVC: 20–30 years. Aluminium: 30–40 years. Cast iron: 50–100+ years with proper maintenance.

Does new guttering need planning permission? No — replacing guttering is considered routine maintenance and does not require planning permission.
