Gutter Replacement Cost by Material and Property
Costs below are for supply and fit of guttering, downpipes, and all fixings, including removal of old gutters. Scaffolding or access equipment is included where required.
| Property type | uPVC | Aluminium | Cast iron |
|---|---|---|---|
| Terraced (2 sides) | £350-£600 | £600-£1,000 | £900-£1,500 |
| Semi-detached (3 sides) | £500-£900 | £900-£1,500 | £1,400-£2,200 |
| Detached (4 sides) | £800-£1,500 | £1,400-£2,400 | £2,200-£3,800 |
| Per metre (supply and fit) | £15-£40 | £35-£65 | £45-£90 |
Prices include removal and disposal of old guttering. Downpipes typically cost £20-£60 per linear metre fitted. London/South East: add 15-25%.
Adding Fascias and Soffits: Combined Job Costs
Many contractors recommend replacing fascias and soffits at the same time as gutters because the scaffolding is already up, labour can be shared, and rotten fascia boards undermine new gutter fixings.
| Job | uPVC fascias & soffits only | Gutters + fascias + soffits |
|---|---|---|
| Terraced house | £600-£1,200 | £900-£1,700 |
| Semi-detached | £900-£1,800 | £1,300-£2,500 |
| Detached | £1,500-£3,000 | £2,200-£4,200 |
Combining both jobs on one scaffolding erection typically saves £300-£600 versus doing them separately.
What Affects Gutter Replacement Cost?
The following factors can move your final quote above or below the typical ranges:
- Material — uPVC is the most affordable and lowest maintenance; cast iron is traditional and long-lasting but heavy, expensive, and requires periodic painting.
- Gutter profile — half-round, square, and ogee profiles all carry different material costs; cast iron ogee gutters for period homes are particularly expensive.
- Number of downpipes — each downpipe adds £20-£60 per metre fitted; a detached home may have four or more.
- Scaffolding and access — single-storey bungalows may only need ladder access; two- or three-storey properties usually require scaffolding or a cherry picker, adding £300-£800.
- Fascia and soffit condition — if fascia boards are rotten, gutters cannot be fixed properly; replacement is essential and adds significant cost.
- Roof overhang and complexity — complex rooflines with hips, valleys, and dormers have more linear metres of gutter and more internal and external angles.
- Gutter guard or leaf filter — adding a mesh or foam filter to prevent blockages costs £3-£8 per metre extra.
- Location — London and South East labour rates are typically 15-25% above the national average.
uPVC vs Cast Iron vs Aluminium Gutters
uPVC (unplasticised polyvinyl chloride) is by far the most popular gutter material in the UK. It is light, easy to install, requires no painting, and is colour-stable for 20-30 years under normal conditions. It is the go-to choice for modern homes and straightforward replacements on period properties where traditional aesthetics are not critical.
Cast iron guttering has been used in the UK since the 19th century and is still the preferred choice for Victorian, Edwardian, and other heritage properties — particularly in conservation areas where planning officers may require its use. Cast iron is heavy, requires painting every 5-10 years, and costs three to four times more than uPVC. However, it is extremely durable and, when maintained, can last the lifetime of the building.
Aluminium guttering sits between the two — it looks similar to cast iron (and can be formed into the same ogee and moulded profiles), is much lighter, and does not rust. Powder-coat finishes are available in a wide range of RAL colours. It is increasingly popular on new-build and contemporary extension projects. Aluminium seamless gutters, roll-formed on-site, eliminate joints and the leaks associated with them.
The Case for Replacing Fascias and Soffits at the Same Time
Fascia boards are the horizontal boards fixed at the eaves to which gutters are attached. Soffits are the horizontal panels that close off the underside of the roof overhang. Both are exposed to driving rain and condensation moisture from within the loft, making rot a common problem in older timber versions.
When rotten fascias are left in place and new gutters fixed to them, the gutters will pull away within a few years as the timber continues to deteriorate. A reputable contractor will identify rotten fascia during the quoting process and recommend UPVC capping or full board replacement. While this adds cost, it prevents a second scaffolding visit and a second round of gutter replacement in a few years' time.
Most contractors price combining the two jobs favourably because the scaffold can be shared and labour spread across a single mobilisation. As a rule of thumb, combining gutter replacement with fascia and soffit renewal saves £300-£600 compared to doing the work separately.
Blocked Gutters Can Cause Serious Damp
Overflowing gutters are one of the most common causes of penetrating damp in UK homes. Water cascading down the wall face saturates brick and mortar, leading to internal damp patches, damaged plasterwork, and potentially mould. If you are buying a property and the survey flags blocked or defective guttering, the cost of downstream damp remediation can far exceed the cost of gutter replacement itself. Factor this into your offer or ask the vendor to rectify before exchange.
