Most homeowners only think about their gutters when something goes wrong. But choosing the right profile and material from the start can mean the difference between a system that lasts 15 years and one that lasts 100. There are five main gutter profiles used on UK homes, each suited to different roof types and aesthetics. Materials range from budget uPVC at around £2 per metre to cast iron at over £100 per metre.
What Are the Main Gutter Profiles in the UK?
| Profile | Typical Use | Capacity | Style |
|---|
| Half-round | Period and modern homes | Standard | Traditional |
| Ogee | Victorian/Edwardian properties | Medium | Ornate |
| Square line | Modern new builds | Standard-high | Contemporary |
| Deepflow | High-rainfall areas, steep roofs | High | Traditional |
| Box | Commercial, flat roofs | Very high | Industrial |
Each profile matters. Fit the wrong one and you risk overflow, structural water damage, or a system that looks jarring against your property.
Half-Round and Ogee Gutters
Half-round is the oldest and most widely used profile in the UK. The semicircular channel promotes steady, fast water flow with minimal debris trapping. It suits cottages, Victorian terraces, and a broad range of modern homes.
Ogee (OG) gutters have a distinctive S-curve profile and became the standard fitting on Victorian and Edwardian homes throughout the UK. They offer slightly more capacity than a half-round of the same nominal width. Ogee gutters are often required on listed buildings and Conservation Area properties where the original profile must be retained.

Square Line and Deepflow Gutters
Square line gutters have a rectangular cross-section and a flat back that sits flush against the fascia board. They handle more water than a half-round of equivalent width. The clean angular profile suits contemporary architecture — they look wrong on period buildings.
Deepflow gutters have the same external profile as half-round but a significantly deeper channel, carrying roughly 40% more water by volume. They were developed for properties in high-rainfall regions (Scotland, Wales, North West England) or buildings with steep-pitch roofs that discharge water rapidly.
UK Gutter Materials: Cost vs Lifespan
| Material | Installed Cost (per metre) | Lifespan (years) | Annual Cost (per metre) |
|---|
| uPVC | £35-£60 | 20-30 | £1.50-£2.50 |
| Aluminium | £55-£180 | 30-40 | £1.80-£5.00 |
| Galvanised Steel | £45-£120 | 20-30 | £1.80-£5.00 |
| Cast Iron | £85-£275 | 50-100 | £0.85-£5.00 |
| Copper | £150-£400 | 60-100 | £1.50-£6.00 |
Cast iron, when maintained, is not dramatically more expensive per year than uPVC — and it eliminates the replacement cost entirely for the lifetime of most buildings.
Most guides tell you what each profile looks like. None tell you how to calculate whether a profile will actually handle your roof.
The Building Research Establishment (BRE Digest 605) provides guidance on rainwater drainage sizing. The key variable is the effective catchment area of your roof: length x width x a pitch factor.
