uPVC vs aluminium vs cast iron guttering: cost and lifespan compared
Guttering is one of those jobs where the material choice quietly decides the price. uPVC is the cheap, everyday option, aluminium sits in the middle, and cast iron is the premium look that period homes often demand. This guide compares the three on cost, lifespan and upkeep so you can choose sensibly, with the real prices below.
The quick version
- uPVC is the most affordable and by far the most common, easy to fit and replace but the shortest-lived of the three.
- Aluminium costs more up front, resists rust, and can be supplied in long seamless runs with fewer joints to leak.
- Cast iron is the dearest by some margin, prized on period and listed homes for its looks, but heavy and in need of repainting over time.
- The real prices below show what each material worked out at once fitting and access were included.
What people actually paid
Real prices, in people's own words
- £2,200“We had all the fascias/soffits/gutters/downpipes etc replaced a couple of months ago. Black + white upvc. Cost £2.2k”
- £3,800“We have a four bedroom detached house (N.W. England) and recently had all the fascias, soffits and gutters replaced in upvc for a total cost of £3800”
- £3,800“We had ours done last November, plus two windows, £3800”

Why the price varies so much
Material is only half the story; the rest is the shape of your roof and how you get to it. A long, simple frontage with one downpipe is cheaper per metre than a house full of corners, valleys and multiple drops, whatever the material. Aluminium is often installed as a seamless system rolled to length on site, which reduces joints but brings a specialist and their kit, so labour differs from clipping together off-the-shelf uPVC. Cast iron is heavy and awkward, so it needs more hands and stronger fixings, and if it is going on a tall or listed building the access and care required push it up further. As with any work at height, scaffolding or a tower can add as much as the guttering when the eaves are hard to reach.
How to pay less
- Match the material to the house rather than the brochure: uPVC is fine on most modern homes and there is little point paying for cast iron unless the property calls for it.
- If you like the cast iron look but not the price, aluminium can be powder-coated to imitate it for a lot less.
- Get three quotes for the fascias, soffits and guttering and make sure each is priced on the same material and profile, or you are not comparing like with like.
- Choose a local specialist over a national firm, since national brands quote above local trades and the difference on a whole-house job can be substantial.
Common questions
Is aluminium guttering worth the extra over uPVC?
It can be. Aluminium lasts longer, does not become brittle in the sun, and seamless runs mean fewer joints to fail, which is handy on a house where getting up to the gutters is a hassle. On a standard home where access is easy and budget matters most, uPVC does the job perfectly well for less.
How long does each type of guttering last?
As a rough guide, uPVC tends to give a couple of decades before it goes brittle and faded, aluminium can run longer with little fuss, and cast iron can last generations if it is kept painted and free of rust. Lifespan depends heavily on maintenance and how exposed your property is.
Do I need cast iron guttering on a period house?
Not always, but sometimes. Listed buildings and homes in conservation areas may be required to keep cast iron or a close match, so check with your local authority first. Where there is no restriction, powder-coated aluminium gives a very similar look with less weight and less upkeep.
