Select from over 52 exclusive and affordable designs.
Each of our stylish radiators comes in an extensive choice of sizes, colours and outputs.
With over 230 colours and special finishes to choose from you are never short of options, whether it's matching your colour scheme, or creating a contrasting feature.
To help choose your colour most radiators and towel rails belong to a colour group which is shown in the overview section of their respective page.
You can also look at all our colour groups within the finishes page where you can see all colours and products available in each group.
To complete the look and really finish off your chosen design, choose from our wide selection of radiator valves and add any accessories that complement your choice. We recommend using TRV valves in all living rooms and bedrooms to maximise the efficiency of your radiators.
Please remember valves will increase the overall width of your radiator unless you select underneath (B2) connections.
