Slimline Electric Radiators

Slimline electric radiators deliver full heating output in an ultra-thin profile — ideal for rooms where wall depth is limited, space is at a premium, or you simply prefer a more discreet heating solution. Our slimline range sits flush to the wall with a minimal projection, making them particularly well-suited to hallways, narrow rooms, and modern interiors where a sleek finish matters.

Slimline Electric Radiators — Maximum Heat, Minimum Depth

Despite their slim profile, these radiators lose nothing in performance. Precise digital thermostats, 7-day programmable timers, optional WiFi app control, and full wattage output are all retained. All models are wall-mounted, supplied with brackets, and connect to a standard 13A supply.

Available in wattages from 500W to 2000W. Free UK delivery on all orders. Use our Electric Heating Calculator to find the correct output for your space.

Where Slimline Electric Radiators Work Best

Slimline electric radiators solve a specific problem: how to heat a room when the available wall depth is limited. In most cases this is a hallway or landing where the space between walls is narrow, a room with fitted furniture that reduces usable wall depth, or a modern interior where a standard-depth radiator would look bulky and out of place.

What Counts as 'Slimline'?

In our range, slimline refers to models with a body depth under 100mm from wall to face. Standard electric radiators typically project 90–150mm. Slimline models project 50–90mm, allowing installation in spaces where a standard unit simply would not fit — or where the reduced visual bulk is preferred for aesthetic reasons.

Slimline Radiators for Small Rooms & Tight Spaces

Hallways, landings, cloakrooms, narrow kitchens, en-suite bathrooms, and compact bedrooms are all environments where slimline electric radiators excel. In these spaces, a standard-depth radiator can feel imposing and impractical. A slimline model gives you the full heating output you need without the bulk — and because electric radiators require no pipework, you have full flexibility in positioning.

Frequently Asked Questions

Do slimline electric radiators heat as effectively as standard ones?
Yes — the wattage output is the same. The reduced depth affects aesthetics and installation flexibility, not heating performance.

Are slimline radiators suitable for bathrooms?
Some models in our range carry IP ratings suitable for bathroom installation. Check individual product specifications for IP rating before purchasing.
