A flat radiator front panel is the quickest way to give a ribbed panel radiator a cleaner, more streamlined look without touching the existing installation. The steel panel simply attaches magnetically over your current radiator, leaving the heating function completely intact. The range includes 40 Belrad models in white, starting from around £60.
Flat front panel or a different solution?
A separate front panel is the right choice when your existing radiator heats well but the corrugated fins are an eyesore. You keep your current connections, mounting points and thermostatic head. The magnetic fixing holds the panel firmly in place without any tools, and the smooth front surface is far easier to wipe clean. This is not a radiator cabinet or cover that encloses the radiator on all sides — the heat output must remain unobstructed at the top and bottom.
If you want a completely new appliance with a flat front already built in, you would be better served by a panel radiator. That does require new connections and brackets. A separate front panel is sufficient when your existing radiator performs well and only the appearance lets it down.
Choosing the right flat front panel for your radiator
Size is the first and most critical factor. Measure the height and width of your existing radiator carefully and compare them against the dimensions listed for the front panel. The Belrad range runs from 500×400 mm to 600×1200 mm, with popular intermediate sizes such as 900×600 mm, 900×800 mm and 600×800 mm. There are 40 fixed sizes available; bespoke sizing is not offered.
- Radiator type: the front panels are compatible with panel radiators of type 11, 21, 22 and 33, provided the external dimensions match. Type 11 has one panel and one convector fin strip; type 22 has two panels and two strips. External dimensions can vary between manufacturers, so always measure before ordering.
- Colour and material: all 40 models are finished in white-painted steel. Steel is not suitable for rooms with prolonged exposure to steam, such as a bathroom without adequate ventilation.
- Price: models range from approximately £60 to £180, depending on size.
Installation: where things commonly go wrong
The most common mistake is fitting the front panel onto a warm radiator. A thin steel panel can bow slightly under heat, and this only becomes visible when light catches it at an angle. Switch the heating off, allow the radiator to cool completely and bleed it if necessary. The magnetic fixing makes installation straightforward, but once fitted, check that the panel sits flat and flush across its entire surface. Your thermostatic valve remains accessible from the side of the radiator; the front panel covers the front face only.
Frequently asked questions
Will a flat front panel fit any panel radiator?
No — Belrad front panels are designed for panel radiators with a standard profile, such as type 11, 21, 22 and 33. Always measure the height and width of your existing radiator and compare them precisely against the panel dimensions. If you are unsure of the type, check the data plate on the side of the radiator.
Which sizes are available as standard?
The range includes 40 fixed sizes, from 500×400 mm to 600×1200 mm. Common sizes include 900×600 mm, 900×700 mm, 900×800 mm, 600×800 mm and 500×1000 mm. If your exact size is not listed, check the product details for the precise cover dimensions — a panel that is too small will not align correctly with the magnets on the radiator.
Does a flat front panel affect my radiator's output?
A front panel does not meaningfully change your radiator's output. The heat output is distributed slightly more evenly across the surface because air no longer flows directly between the fins, but the difference in capacity is negligible. The front panel is an aesthetic and practical upgrade, not an improvement to heating performance.
