Panel radiators are one of the most efficient and versatile heating options for UK homes. Designed to deliver strong, consistent warmth, they are available in a variety of sizes and styles to suit every room. Whether you need a slimline model for a hallway or a larger radiator for an open-plan space, panel radiators provide a practical balance of performance and value.
We supply both single and double panel radiators, giving you the flexibility to choose the right heat output and design for your property. Built from high-quality materials, these radiators are durable, low-maintenance, and suitable for both modern and traditional interiors.

Our designer panel radiator range offers a choice of shapes, sizes and layouts for different interiors. Whether you prefer the clean lines of flat panels or the rounded appearance of oval designs, start by considering the space available and the heat your room needs.
Single panel radiators have one layer of heating panels or tubes, while double panel radiators have two.
A single panel model generally has a shallower profile. A double panel model is usually deeper and can provide more heat output when comparing similar dimensions and designs.
Check the output for the exact size you want rather than choosing by the number of panels alone. Also consider the radiator’s projection from the wall, especially in smaller rooms or walkways.
Flat panel radiators have a clean, angular appearance that works well with simple contemporary interiors.
Oval radiators offer a softer look with rounded heating tubes. Both styles are available in different configurations, so compare their dimensions and listed outputs alongside their appearance.
Horizontal models suit wider wall spaces, while vertical designs can fit taller, narrower areas. Think about doors, furniture and access to the valves when choosing a position.
Use our BTU calculator to estimate the room’s heating requirement, then compare suitable models. Finish your choice with white for a classic look, black for contrast or anthracite for a dark grey alternative.
