Select a gutter profile below to view specific sizes, capacities, and compatible downpipes and fittings:

Half Round Gutters: Classic smooth lines providing efficient water flow for standard domestic roofing.

The Manufacturing Difference: Durability Engineered by Design

Not all metal guttering supplies are created equal. While many competitors cut corners by simply degreasing and painting, Alugutter employs a rigorous, industry-leading 5-stage finishing process to completely prevent paint failure:

Hand Sanding: Every individual aluminium gutter length and fitting is manually abraded to create a superior surface key.
Chemical Degreasing: Thorough removal of all manufacturing oils and surface contaminants.
Etch Priming: A specialist, high-adhesion primer is applied to chemically bond with the marine-grade alloy.
Powder Coating: Flawless application of Interpon D1036 architectural-grade polyester powder.
Curing: Precision baked to achieve a hard-wearing, scratch-resistant, and fade-resistant finish.

Uncompromising Quality Aluminium Gutters

If you are looking for a replacement rainwater system that seamlessly combines structural strength, lasting durability, and modern style, explore our comprehensive range. These premium metal gutters meet all eaves-line roofing requirements, offering profiles, sizes, and colours engineered to withstand diverse environments and guarantee maximum protection against the elements.

At Alugutter, we pride ourselves on supplying superior aluminium roofing products at highly competitive factory-direct prices. Our dedicated technical team is always on hand to provide expert guidance for your specific build. Thanks to our fade-resistant polyester finishes, these rainwater systems deliver unmatched longevity—expect a functional life expectancy of around 50 years, with the coating lasting well over 25 years with just basic care. Suitable for domestic homes, commercial premises, and industrial warehouses, all our aluminium guttering items are proudly designed and manufactured right here in the UK.

Easy Install Snapfit Jointing System

Save time and labour costs with our unique Snapfit twin-seal jointing method, which facilitates quick, simple, and incredibly neat installations. These lightweight metal gutters are perfectly suited for installation by any competent tradesperson or experienced DIYer. They perform exceptionally well in extreme UK weather, including high winds or heavy snowfall, with fully adjustable bracket spacing to accommodate high-exposure conditions.

Non-Combustible Fire Rating for Aluminium Gutters

Safety is paramount in modern construction. Our aluminium rainwater systems proudly achieve a Class A2-s1,d0 fire rating, making them a safe, non-combustible choice legally permitted for use on buildings of any height, including high-rise commercial and residential structures.

Maintenance Tips for Long-Lasting Aluminium Gutters

Ongoing maintenance remains refreshingly straightforward. Our low-maintenance metal gutter designs require only occasional cleaning with fresh water and a soft brush to keep them looking pristine. We recommend inspecting joint integrity and removing leaf debris annually—or twice yearly in highly exposed marine or wooded settings.
After decades of extended service, if the polyester powder finish ever begins to dull, the system can be easily overpainted with a quality exterior metal paint, further extending its life.

Aluminium Gutters — Frequently Asked Questions

We recommend, as with any other painted surface, that periodic cleaning is carried out. Polyester powder coated aluminium requires only a soapy water solution to bring back the original appearance. Once a year, or twice in a marine environment, we recommend that the gutter system is cleaned and joint integrity is checked. Any collected gutter debris should also be removed.

Yes, aluminium is 100% recyclable, requires less energy to produce than alternatives like uPVC, and has a low carbon footprint over its lifecycle. It does not leach harmful chemicals and can be reused indefinitely without quality loss.

Aluminium gutters offer superior durability, lasting up to 50 years without rusting, rotting, or cracking — unlike uPVC which can degrade in UV light and extreme weather. They are lightweight, recyclable, and provide better fire resistance (non-combustible, Class A1 rated). While initial costs are higher, long-term savings come from minimal maintenance and exceptional longevity.

Aluminium guttering is typically more expensive than a uPVC equivalent but is quite comparable in price to a high-end uPVC system. As our aluminium gutters carry a 50-year functional life expectancy, they will last considerably longer than a uPVC system, saving money in the long term.

Our aluminium gutters are supplied pre-coated with a durable polyester powder paint in the colour of your choice. With minimal maintenance, our architectural grade paint can provide a decorative finish for in excess of 25 years.

Following many years of service, once the paint finish loses its original lustre, the painted surfaces can be overpainted using a good quality metal paint, providing a durable decorative finish for many years to come.

High-quality marine-grade aluminium gutters can last 50 years or more with correct installation and occasional cleaning. Their polyester powder coating resists fading and corrosion, making them ideal for the UK's variable climate.

Aluminium does not burn and is classed under BS476-4 as a non-combustible building material, and Class A1 under European regulations. Our decorative polyester powder coatings are rated: BS476-6 = Class 0 (Fire propagation), BS476-7 = Class 1 (Surface spread of flame), EN13501-1 = A2-s1,d0.

Our products are supplied with installation guides and can be installed by any competent tradesperson or confident DIY enthusiast.

Use either a hack saw with 18 teeth to 1 inch blade, or a circular saw with an appropriate aluminium cutting blade. Angle grinders are also suitable with a thin cutting blade. If using an angle grinder, dip the blade into Tallow to lubricate it — this makes for a much faster and neater cut.

Modern buildings now have heavily insulated roofs to prevent heat loss, which means snow build-up on roofs is becoming more common. The BS EN12056-3 stormwater drainage design standard advises that gutters should be installed so that the front lip aligns with the pitch of the roof. This prevents sliding snow impact and the gutters becoming damaged.

The use of incompatible screws and fixings will cause electrolytic corrosion between the two metals. Only austenitic stainless steel fixings as supplied by Alugutter should be used.

BS EN12056 is the current design standard for sizing rainwater goods. We also offer a free drainage design service and can recommend suitable products — please email your roof plan and elevation drawings via our contact page.

The style of eaves gutter system is usually dictated by the style of the building. Traditional styles are available conforming to BS 8530 and we also offer contemporary styles with a modern Snapfit jointing method.

All gutter and pipe joints should be sealed with Alugutter Code SU1 low modulus, high-performance silicone sealant. Joint surfaces must first be cleaned with a PVC solvent cleaner and allowed to dry prior to applying the sealant.

Small domestic gutters are generally installed to falls of 1:600 to enhance the flow towards an outlet. However, our systems are all high performance in terms of flow capacity and can also be installed level if preferred.

All metal gutters expand and contract, but the amount of thermal movement depends on the metal used. Aluminium expands approximately 1 mm per 1 m, but does not expand as much as uPVC systems. All of our systems are designed with a 3–4 mm expansion gap at each joint to allow for thermal movement without breaking the silicone joint seal.

Aluminium vs Cast Iron Gutters: The Definitive Comparison

When replacing or specifying rainwater goods, the choice between aluminium gutters and cast iron gutters is one of the most common questions posed by both homeowners and trade installers. Both materials have a long history in UK roofline protection, but advances in aluminium manufacturing mean the two are no longer equivalent alternatives — they serve fundamentally different requirements.
