Slim Radiators
When you have limited wall space, a slim radiator is the best way to keep your room warm without taking up too much room. These compact designs are ideal for hallways, kitchens, or behind doors where space is tight and a standard radiator will not fit.
To make the most of your wall height instead of width, you can explore our full collection of vertical radiators. These tall designs offer excellent heat output while using very little horizontal floor space.
Our slim models are made from high-quality materials that ensure your home stays warm throughout the British winter. Whether you need a subtle white finish or a modern anthracite look, our range provides efficiency and style in equal measure.

Frequently Asked Questions About Slim Radiators
What rooms are slim radiators best suited to?
Slim radiators are specifically designed for spaces where a standard radiator would not comfortably fit, making them the ideal choice for narrow hallways, box rooms, cloakrooms, and bathrooms where wall space is limited. Their compact depth also allows them to be installed along walls, tucked into corners, or fitted into small gaps between furniture without obstructing the room.
Are slim radiators powerful enough to heat a room?
Yes, slim radiators can deliver a strong heat output despite their narrow profile, as their tall surface area compensates for their reduced depth by radiating heat effectively from top to bottom. The key is ensuring the model you choose meets the BTU requirement for your specific room, which you can calculate using our BTU calculator before purchasing.
How slim is a slim radiator?
Our slim radiators have an ultra-narrow profile, with selected models projecting minimally from the wall whilst reaching near floor to ceiling height, making them one of the most space-efficient heating options available. Exact depth and dimension details are listed on each individual product page so you can confirm the fit before purchasing.
Are slim radiators only available in a vertical orientation?
The majority of slim radiators in our range are designed to be wall-mounted vertically, as this orientation is what allows them to deliver a useful heat output from such a narrow frame. If you need a compact radiator that sits horizontally, our small bathroom radiators range includes low-level horizontal options designed for tight spaces.
What materials are slim radiators made from?
Our slim radiators are available in aluminium, which heats up quickly, requires less water content, and is 100% recyclable, making it a strong choice for energy-conscious homes and heat pump systems. Aluminium models feature Trio paint technology and an anodised coating for a durable, easy-to-clean surface, and come with a 5-year guarantee.
What colours do slim radiators come in?
Our slim radiators are available in white, anthracite, and black, giving you the flexibility to complement or contrast with your existing interior scheme. Colour availability varies by model, so it is worth checking the individual product page for the specific options before purchasing.
Can slim radiators be installed in a corner?
Yes, the compact depth and narrow width of slim radiators makes them one of the most versatile radiators for corner installations, where they can heat areas of a room that a larger radiator would not reach. This flexibility makes them particularly useful in awkward rooms where standard wall positions are occupied by doors, windows, or fitted furniture.
Do I need special valves for a slim radiator?
Slim radiators are compatible with standard thermostatic radiator valves (TRVs), which are sold separately and not included with the radiator. Browse our full range of radiator valves covering angled, straight, and thermostatic options across a wide selection of finishes to find the right pairing for your slim radiator.
