Choosing a Rainwater System

The right rainwater system transforms a building’s exterior.

Have you considered the impact your choice of rainwater system has on the finish of a project?

We’ve summarised the options to help you decide.



A UPVC rainwater system is a relatively low cost solution. This, coupled with it’s ease of installation and maintenance makes UPVC the popular choice. However, it has a shorter life expectancy, and is vulnerable to damage from UV rays which can result and cracking and leaking.


Cast Iron Effect guttering is a great replacement for cast iron on traditional properties. You retain an authentic heritage look but with all the benefits of standard UPVC rainwater systems. Our system has an extremely durable finish which gives extra UV protection over standard UPVC. It is also lightweight and therefore easy to install.


Aluminium rainwater systems are inspired by Cast Iron guttering, providing the traditional look of cast iron with the benefits of aluminium. It’s easy to install, is low maintenance, and is lightweight but robust. Aluminium also has a long life expectancy. More than 90% of the aluminium used is recycled, making it a sustainable solution too.


Steel is a brilliant material for rainwater systems. It’s lighter than cast iron, easier to handle than aluminium and there is minimal thermal movement compared to plastic. We supply the Lindab system which has a high-build polyester paint finish which is UV stable and will not fade or crack. It is also provided with a 15 year guarantee.

Cast Iron

Cast Iron guttering is aesthetically pleasing, therefore satisfies the requirements of traditional architecture. Cast iron provides longevity; with the correct installation, systems can last over 100 years, making it a cost effective solution. It requires minimal maintenance and because it is a natural product, it is 100% recyclable.

Don’t forget to also consider the profile of gutter and downpipe when making your choices. You can see the different profile options for each product on their individual pages (click the buttons above). The most common profiles are ogee, square, round and deep flow. Traditional houses often have the half round profile, but the ogee profile is also a lovely look as seen in this case study. Square gutters offer a contemporary look – perfect for a modern style.


All of our rainwater systems are available in a wide range of colours so take this into consideration when looking at the options. Aluminium and cast iron systems can be powder coated in any BS or RAL colour.
