If you need a quality heating solution but don't have much space for it, a 400mm radiator could be exactly what you're looking for. Small in stature but powerful in their performance, our range of 400mm-wide and high radiators are ideal for optimising heating in tight spots like bathrooms, along with office and living spaces.

Take your pick from a range of traditional and modern 400mm radiators available in both vertical and horizontal layouts. We only feature brands we know you can trust, like Stelrad and Purmo, so you can be confident you're getting a quality product, no matter what option you go for.

What's more, if you spend £50 or more on your order with us, we'll deliver to you free of charge. Start your order online right away.

Whatever your needs, we've got a 400mm radiator for you. Whether you're looking for a budget buy or a premium option, a simple single panel solution or a high-performance double convector model, we've got you covered.

Of course, it's not just about practicality or budget, but style as well. As well as our traditional white panel radiators that you can get for a great price, you'll also find a variety of modern options available like our flat panel towel radiators that offer a sleek and contemporary finish. Once you've figured out the style you prefer, you can choose the finish you like, the height you need and output you require.

If you're looking to narrow you search down, use the filters at the left-hand side of the page to whittle things down by BTU/h, type, colour, height, brand, and more.

One of the great things about going for a small heating option like a 400mm radiator is the cost. Prices on simple, high-quality options like our Stelrad Halcyon single panel radiators start from just over £20, and you'll find all sorts of options available for under £100.

If you want to push the boat out, take your pick from premium options like a tall Stelrad Softline Deco Double Convector 1800mm x 400mm radiator or a striking black Plan Concept K2 Vertical Double Panel model. Prices here can push up into the £500 to £700 range, but it's all about what suits your requirements, preferences and, most importantly, budget.

Rest assured, there's an option for everyone in our catalogue. Plus, with 5 to 15-year guarantees available across the range and free delivery available on all orders over £50, we promise great value on any 400mm radiator you order.
