With straightforward installation across the Brett Martin ranges — including the innovative CLIP&SEAL on industrial rainwater management systems — it has never been easier to install sturdy, watertight guttering on your project.

 

uPVC Guttering

uPVC guttering is one of the most popular options for both domestic and commercial use. It’s lightweight, easy to handle, and simple to install — making it a practical choice for contractors and DIYers alike. Available in a range of profiles and sizes, it suits most roof types and can be fitted quickly using standard tools.

One of the main advantages of uPVC is that it doesn’t corrode or rust. It stands up well to the elements and requires very little maintenance over its lifetime.

So, if you’re looking for a cost-effective solution that still offers long-lasting performance, PVC guttering is hard to beat.

We stock a wide selection of uPVC gutters, with both square and half round options available, as well as downpipes and fittings to help you get the job done.

 

Cast Iron Guttering

Cast iron guttering is a traditional option that’s often used on repairs to period properties and buildings in conservation areas. It offers a classic appearance and a solid, weighty feel that many people prefer when working on heritage sites. Cast iron is incredibly strong and, when properly maintained, can last for decades - even over a century in some cases.

Although it’s heavier and takes a bit more effort to install than plastic alternatives, this type of guttering delivers excellent durability and weather resistance. It particularly benefits buildings that need a hard-wearing system with an authentic look.

At Cotterill Civils, we supply a wide selection of cast iron gutters, including square and half round guttering, as well as all the fittings you will need to meet a variety of architectural styles and requirements.

 

Half Round Guttering

 Half round guttering is a common and versatile choice, suitable for everything from residential homes to light commercial buildings. With its traditional smooth, curved shape, it offers good flow capacity, allowing rainwater to run off quickly and efficiently, reducing the risk of blockages.

This style of guttering is simple to install and easy to maintain, making it a popular option for both new builds and replacement jobs. Half round guttering also offers a neat, traditional look that works well with most roof types.

At Cotterill Civils, we stock half round guttering in a variety of sizes and materials, along with a full range of compatible fittings.

This means, whether you’re working on a repair to your home's exterior or a larger commercial building, you’ll find all the half round guttering you'll need to complete the system with ease.

 

Guttering Supplies for Commercial Properties

Commercial buildings often require larger, more robust guttering systems to cope with the higher volumes of rainwater that come with bigger roof areas.

Whether it’s a warehouse, factory, retail unit, or office block, choosing quality guttering with good flow capacity is key to protecting the structure and avoiding costly water damage.

At Cotterill Civils, we stock a wide range of guttering options suitable for commercial projects, including high-capacity profiles and durable materials designed to handle demanding conditions. Our Brett Martin industrial rainwater systems are an excellent choice, thanks to their strength, flow capacity, and reliable performance.

We also offer all the fittings and accessories you need to complete the job — from downpipes and brackets to bends and connectors — with options available in both uPVC and metal.

If you’re not sure what’s best for your job, our team is always on hand for support.

Frequently Asked Questions

How much does it cost to replace gutters in the UK?

For a standard semi-detached house in the UK, you can expect to pay between £500 and £1,000 for a complete gutter replacement, or between £24-£40 per metre. However, this can vary based on the type of material – with higher-end materials, such as aluminium or copper, typically costing more than uPVC guttering supplies, for example. Other factors that can influence the cost of replacement gutters are the length and complexity of the installation, as well as the condition of the existing fascia boards. As a general guide, longer lengths and more complicated installations will be more labour-intensive, requiring more time and increasing the overall price. For more information about the cost of gutters, get in touch with the team at Cotterill Civils.

 

Do you need scaffolding to replace guttering?

Scaffolding isn’t required to replace gutting but it may make the job easier and safer. However, if scaffolding isn’t in your budget, the job can be completed with any suitable and stable ladder on single-story homes or lower structures.

For the best advice on replacing your gutters, talk to a professional gutter installer. They can check out your situation and suggest the right way to go about your gutter replacement project.

 

How should guttering be fitted?

Fitting guttering involves a few key steps. First, the old gutters are removed, and the soffits and fascias are checked for any damage. Next, brackets are attached to the fascias to support the new gutters. The gutters are then measured and cut to the appropriate length, ensuring they slope slightly towards the downpipe for proper drainage. The sections are joined securely to avoid leaks, and end caps are added. The downpipe is fitted, directing water away from the house's foundation. It's important to make sure the gutters are securely attached and have a slight downward slope for efficient water flow. Regular maintenance, such as clearing debris, is also essential for keeping gutters functioning properly. To find out more about the gutters we supply at Cotterill Civils, get in touch with us on 0121 351 3230.

 

What’s the difference between round and square guttering?

Round guttering, as the name suggests, has a circular cross-section which resembles a pipe, whereas square guttering has a more angular, box-like shape. Some people prefer the modern, clean lines of square gutters, whilst others find the traditional half round look more appealing. Both function similarly, collecting and directing rainwater away from the roof, but their aesthetic differences can influence the overall appearance of your home. To find out more about guttering, downpipes, and fittings, contact Cotterill Civils. We will be more than happy to share our expertise and offer any help.

 

What size downpipe do I need?

The size of downpipe you need will depend on a few key factors — mainly the size of the roof area, the average rainfall in your location, and the flow capacity of the guttering system you've chosen. It's important to get this right to make sure rainwater is carried away quickly and doesn't back up or overflow. For most domestic properties, a 68mm round downpipe or a 65mm square downpipe is usually sufficient. These are designed to cope with the water run-off from typical house roofs, and they’re widely used for replacement or new build work. If you're working on a larger building, such as a commercial unit, school or agricultural shed, you’ll likely need something bigger — often 75mm, 100mm, or even 150mm in diameter, depending on the size and pitch of the roof. In these cases, it's a good idea to check the flow rate of the system and speak to a supplier or installer who can help you match the right size to your project. It's also worth noting that using multiple downpipes to share the load can be a more practical solution in some situations, especially where a single large pipe isn’t suitable or would look out of place. Brackets, outlets and bends are also available in different sizes and colours to match your chosen pipe. If you’re unsure what size is best for your job, the team at Cotterill Civils can help you work it out.
