Guttering repair in London costs £100–£300 for minor work such as resealing joints or refitting a section, while a full UPVC gutter replacement on a terraced or semi-detached house runs £800–£2,000 in 2026. A straightforward gutter clearing costs £80–£150. Prices depend mainly on access: a job reachable from a ladder or tower is far cheaper than one needing scaffold. This guide breaks down every gutter job by price, and explains why failing gutters are worth fixing before they cause damp.
How much does guttering repair cost in London?
Most gutter problems are small jobs, and they should be priced as such. A blocked or overflowing gutter that simply needs clearing costs £80–£150 for a typical terraced or semi-detached house. A minor repair, resealing leaking joints, refitting a sagging length, replacing a cracked bracket or a single section, falls between £100 and £300.
The cost jumps when the whole run has failed. A full UPVC gutter replacement on a terraced house costs roughly £800–£1,400, and £1,200–£2,000 on a larger semi-detached property, including new gutters, brackets, outlets and the labour to strip out the old system. Fascias, soffits and downpipes are usually priced on top.
The single biggest variable is access. If the roofline can be reached safely from a ladder or a mobile tower, costs stay low. If the height, a conservatory below or a busy pavement means scaffold is required, expect to add £300–£900 for the access alone. We always itemise access separately so you can see exactly what you are paying for.

How much does gutter cleaning cost in London?
Gutter cleaning is the cheapest and most worthwhile money you can spend on a roofline. For a standard two-storey London terrace, clearing the gutters of leaves, moss and silt costs £80–£150. A larger detached property, or one with extensive runs and several downpipes, sits at £150–£250.
The price reflects access and volume rather than the cleaning itself. Many firms now use high-reach vacuum systems that clear gutters from ground level with a camera on the pole, which keeps the cost down because no ladder work or scaffold is needed. Where the roofline genuinely cannot be reached from the ground, a tower or ladder access adds to the figure.
We recommend clearing gutters at least once a year, and twice where there are mature trees nearby. It is far cheaper than the damp repairs that follow when a blocked gutter overflows all winter, which is work we carry out constantly.
Why a failing gutter causes damp and leaks
Guttering is not a cosmetic feature; it is the property's first line of defence against water. When a gutter blocks, leaks at a joint or pulls away from the fascia, rainwater no longer runs to the downpipe. Instead it cascades down the wall, soaks into the brickwork and saturates the area behind the gutter.
The consequences are exactly the problems we are called out to repair. Persistent penetrating damp on internal walls, often appearing as tide marks or blown plaster at first-floor level, is very frequently traced back to an overflowing gutter directly outside. Rotten fascias and soffits follow, then water gets into the roof edge and eventually the loft.
This is why we treat guttering and damp as one job rather than two. Repairing the plaster inside without fixing the gutter outside guarantees the damp comes back. When we survey a damp wall, the roofline is one of the first things we inspect, and resolving a £150 gutter fault often prevents a £1,500 damp and plastering bill.
Fascias, soffits and downpipes: the rest of the roofline
Gutters rarely fail in isolation. The fascia is the board the gutter is fixed to, the soffit is the panel that closes off the underside of the roof edge, and the downpipes carry water to the ground. When a gutter has been overflowing for years, the timber behind it usually rots, and replacing the gutter alone leaves it hanging on a failing board.
Replacing fascias and soffits in low-maintenance UPVC typically costs £40–£75 per metre supplied and fitted, depending on access and whether old timber needs cutting out. On a period property where timber suits the building better, we repair and redecorate rather than replace.
Downpipes cost £150–£400 to renew, including new clips, outlets and hoppers, and ensuring the discharge runs into a gully rather than spilling against the wall. Where the whole roofline is being renewed, doing gutters, fascias, soffits and downpipes together is more economical than returning for each in turn, because the access cost is only paid once.

Access: ladder, tower or scaffold?
Because access drives the price of every roofline job, it is worth understanding the options. For a single-storey extension or a low gutter, a ladder is often sufficient and adds little to the cost. For most two-storey work, a mobile access tower is the safe, sensible choice and is far cheaper than scaffold while still allowing the operative to work with both hands.
Scaffold becomes necessary where the work spans a long run, where there is no safe ground for a tower, where a conservatory or extension sits below, or where the job is part of wider roof or wall work. Scaffold for a typical gutter run costs £300–£900 depending on height and length, and that is the access cost before any guttering work begins.
We assess access at the survey and always tell you which method the job needs and why, so the access line in your quote is never a surprise. Where we can avoid scaffold safely, we do, because it keeps your bill down.
Repair or replace? Knowing when each makes sense
Not every gutter problem needs a new system. If the runs are sound and only a few joints leak or a bracket has failed, a targeted repair at £100–£300 is the right answer and will give years more service. Resealing modern UPVC joints, refitting fallen sections and replacing a cracked length are all straightforward.
Replacement makes sense when the system is old cast iron that is rusting through, when UPVC has gone brittle and cracks wherever it is touched, when the falls are so wrong that water pools rather than flows, or when so many sections have failed that repairs no longer add up. At that point a full UPVC replacement at £800–£2,000 is the more economical long-term decision.
We give an honest recommendation either way. If your gutters have years left and only need a repair, that is what we will quote; we would rather fix what you have than sell you a system you do not need yet.
Getting an accurate guttering quote
Guttering quotes vary because every roofline is different, so a fixed price needs a proper look. At London Refurbishments & Leak Repairs we offer a free survey and a fixed quote, with no obligation, so you know the cost before any work starts. We inspect the full run, check the fascias and soffits behind it, identify whether a leak has already caused internal damp, and recommend the most economical access method.
All figures in this guide exclude VAT. Most gutter repair and replacement work is standard-rated at 20%, so factor that in when comparing quotes; a price that looks low may simply have left the VAT off. We show VAT clearly so the figure you see is the figure you pay.
Frequently Asked Questions
How much does it cost to repair guttering in London?
A minor guttering repair in London costs £100–£300 in 2026, covering resealing leaking joints, refitting a sagging section or replacing a cracked length. Clearing a blocked gutter costs £80–£150. A full UPVC replacement on a terraced house runs £800–£1,400. These figures exclude VAT, and scaffold where required adds £300–£900.
How much does gutter cleaning cost in London?
Gutter cleaning in London costs £80–£150 for a standard two-storey terrace and £150–£250 for a larger detached property. Many firms now clear gutters from the ground with high-reach vacuum systems, which keeps the cost down. We recommend clearing gutters once a year, or twice where there are nearby trees, to prevent overflows and damp.
How much does it cost to replace guttering on a house?
Replacing all the guttering on a terraced house with new UPVC costs £800–£1,400 in 2026, rising to £1,200–£2,000 on a larger semi-detached property. That covers new gutters, brackets and outlets plus removal of the old system. Fascias, soffits and downpipes are priced separately, and access by scaffold adds £300–£900 if required. Figures exclude VAT.
Can a leaking gutter cause damp inside the house?
Yes, very commonly. An overflowing or leaking gutter pours water down the external wall, where it soaks into the brickwork and shows inside as penetrating damp, tide marks or blown plaster, usually at first-floor level. We frequently trace internal damp back to a faulty gutter, and fixing a £150 gutter fault often prevents a much larger damp repair bill.
Do I need scaffold for guttering work?
Not always. Many gutter repairs and cleans are done safely from a ladder or mobile access tower, which keeps costs low. Scaffold is only needed for long runs, where a conservatory sits below, where there is no safe ground for a tower, or as part of wider roof work, and it adds £300–£900. We assess access at the free survey and avoid scaffold wherever it is safe to do so.
