Central heating radiators

Central Heating Radiators UK

Most central heating radiators in the UK are replaced for one of two simple reasons: the old one finally gave up, or the room never felt warm enough to begin with. This is your opportunity to get it right. Instead of settling for a thin-walled substitute from a big-box retail shelf, you can choose central heating radiators that actually hold their warmth—heating that earns its place rather than just filling a gap on the wall.

We’ve moved away from the flimsy "minimum specification" that leads to internal corrosion and those annoying whistling pipes. These radiators for central heating are built to European standards, meaning they are thick enough to retain heat long after the boiler switches off. Whether you are running a traditional boiler or a modern heat pump, these units handle the job without making your system work overtime. It is about hardware built to last, not just to look good in a brochure.

Our range is designed for real British layouts, not idealised showrooms. We offer high-output column models for draughty hallways and vertical panels for when wall space is at a premium. Because we don't think you should pay more for style, we provide over 200 RAL colours as standard across our central heating radiators UK range. You get the exact finish you want without the unnecessary surcharge—because proper heating shouldn't require a premium for looking right.

What actually makes a radiator “good” or “bad”?

Most failures are performance-based. A radiator that never quite gets the room comfortable isn't "almost right"—it is undersized or too thin to retain heat. In British homes, especially older terraces, thermal mass is a requirement, not an option. If it struggles on a cold January evening, it was never fit for purpose.

How do I know the size will actually heat the room?

Heat loss must be calculated based on room volume, insulation, and glazing. Measuring the wall space is a mistake. Selecting a unit based on available space rather than required BTUs is the most common error UK homeowners make. If the radiator is undersized, the room will never reach temperature, regardless of how long the boiler runs.

Will these work with a heat pump?

Yes, provided the heat pump is designed specifically for radiator-based heating systems. Radiators require a heat pump capable of producing flow temperatures of around 50–55°C. Low-temperature systems alone are not always sufficient for traditional radiator setups. When a correctly specified radiator is paired with a heat pump optimised for radiator operation, the system delivers stable and predictable heating performance.

Are they compatible with standard UK pipework?

Yes. Our units use standard UK pipe centres, meaning replacements are straightforward when dimensions match. Relocating pipework or upgrading an entire system is a broader task, but for like-for-like swaps, the installation should be predictable rather than disruptive.

Is professional installation required?

For a direct swap where pipe centres match and the system can be safely drained and repressurised, competent DIY is an option. However, for layout alterations or heat pump integration, a qualified heating engineer is necessary. Poor installation undermines high-quality hardware.

How long should a quality radiator last?

Twenty years is a realistic expectation for a properly manufactured unit. Premature failure is almost always due to thin steel and internal corrosion. Longevity is decided at the point of purchase; a budget unit built to a minimum specification rarely lasts beyond a decade.

Steel or aluminium — which is better for a British home?

The choice depends primarily on how the space is used. Steel radiators retain heat longer after the heating cycle stops, providing greater thermal stability in homes heated throughout the day. Aluminium radiators respond more quickly, making them suitable for intermittently heated rooms. The decision should be based on usage rather than which material appears more modern. However, aluminium and steel radiators should never be mixed within the same heating system. A system should be fitted entirely with aluminium radiators or entirely without them, as combining different metals can lead to corrosion issues and long-term system failure.

Can I choose a colour other than white?

Yes. Over 200 RAL colours are available as standard. Colour choice is an aesthetic decision; it should not affect the engineering cost or carry a premium surcharge.

CENTRAL HEATING RADIATORS - Room radiators

Why Choose Our Central Heating Radiators?

Central heating radiators are not an exciting purchase. They are a practical one—and that is exactly how we treat them. You need hardware that matches your pipe centres, delivers the thermal output your room requires, and remains trouble-free years from now. We build to that standard.

Our range prioritises material density and internal protection over minimum production costs. The true difference is not visible at the point of purchase but becomes apparent over time—in rooms that maintain their temperature, systems that run efficiently, and radiators that do not corrode from the inside out.

Rather than mass-market construction, we provide high-grade options for real-world British homes. Each unit is built to order, allowing you to specify the exact dimensions, connection types, and finishes required for your space. The result is a bespoke piece of hardware manufactured specifically to your requirements. All models integrate with standard UK central heating and modern heat pump systems. Over 200 RAL colours are available as standard, ensuring your interior finish does not carry a hidden premium. Mainland UK delivery is included on all orders.

These are radiators chosen by people who want the job done properly the first time. Not the cheapest option on the shelf—and not the most expensive either. Just the right one.
