Most gutter repair jobs cost £180–£250 for a single leak, loose bracket or blocked section, while a full gutter replacement on an average home runs £1,000–£1,600. The right call usually comes down to how much of the run is affected: a localised problem is a repair, but sagging, cracking or leaking along multiple sections almost always means it’s cheaper in the long run to replace the whole thing at once.
Repair is the right call when the problem is limited to one or two sections and the rest of the run is sound. A single leaking joint, a loose bracket, a cracked length, or a blockage from leaves and debris are all straightforward repairs rather than a reason to replace the whole system.
Full replacement makes more sense once you’re seeing problems along multiple sections, or the guttering is old enough that patching one part just moves the problem to the next. According to Checkatrade’s gutter replacement guide, water spilling over the gutters instead of draining away, or damp patches creeping down an outside wall, are both signs the whole system may need replacing rather than a single repair.
[YOUR EXPERIENCE HERE — the skill will not invent this]
Most single gutter repairs cost £180–£250, including the call-out, with individual replacement parts such as brackets or short lengths running £18–£42 depending on the component. That’s based on MyJobQuote’s UK guttering cost data, which puts a typical roofer’s specialist rate at £55–£65 an hour, or around £40 an hour for an assistant.
Full gutter replacement typically costs £1,000–£1,600 for an average home, supplied and fitted, with the exact price depending on material and how many metres need covering:
| Material | Supply & Fit Cost per Metre |
|---|---|
| uPVC | £40 – £50 |
| Steel | £40 – £60 |
| Zinc | £50 – £72 |
| Cast iron | £50 – £75 |
| Aluminium | £55 – £78 |
| Copper | £65 – £95 |
By property, a typical two-bed terrace (around 26m of guttering) runs £1,050–£1,300 in uPVC, a three-bed semi (32m) £1,300–£1,600, and a four-bed detached (46m) £1,850–£2,300. Choosing a premium material like cast iron or copper instead of uPVC pushes the total up significantly, since both the material and the specialist fitting cost more per metre.
Well-maintained guttering typically lasts around 20 years before it needs replacing, though this varies by material — uPVC tends to sit at the shorter end of that range, while cast iron and aluminium can last considerably longer if properly maintained. Regular clearing and an annual check of joints and brackets is the single biggest factor in getting the full lifespan out of any material.
A straightforward repair — a joint, a bracket, or a single section — is usually a same-day job, often two to three hours including access. A full replacement typically takes five to six hours for an average home’s run, though larger or more complex properties with multiple downpipes and awkward access can take a full day.
uPVC is the most common choice for most homes because it’s the cheapest to buy and fit, needs no painting, and copes well with the UK climate. Aluminium and cast iron cost more but last longer and suit period or higher-spec properties better, particularly where the existing fascias and roofline are already in a traditional material — worth discussing against what’s already on the property before assuming uPVC is the default.
Regular clearing is the single biggest thing you can do to avoid an unplanned gutter repair — most blockages and the overflow damage they cause are preventable with routine maintenance rather than a reactive fix. Clear leaves and debris at least twice a year, more often if you’re near overhanging trees, and check joints and brackets after any major storm.
A proper quote should say clearly whether it’s covering a repair or a full replacement, name the material, and state how many metres are involved — vague per-job pricing usually means the scope isn’t actually fixed yet.
