Why choose Paladin cast iron radiators?

Our moulds produce radiators for us and nobody else: no shared production lines, no mass-manufactured compromises. Every section is hand-assembled, pressure-tested and finished at our factory in Lincolnshire before it leaves the building. We’ve been manufacturing cast iron radiators for over 15 years, and our radiators are installed in period properties, listed buildings, new builds, hotels, restaurants and commercial spaces across the UK.

That level of control means we can offer genuinely bespoke sizing: radiators built to your exact section count, finish and specification. It also means the ornate detail on our castings stays sharp, because our moulds aren’t worn down by mass production across multiple product lines.

Our finish options go beyond standard paint. Choose from our metallic colour range, Farrow & Ball and Little Greene partnership colours, aged paint effects or hand-polished finishes. If you have a specific shade in mind, we’ll colour-match it. Browse the full paint colour range.

Our cast iron radiator range covers everything from compact models for bay windows and conservatories to tall, multi-column radiators for period hallways and high-ceilinged rooms. Choose from 2-column, 3-column, 4-column and 6-column configurations to match your heat output and wall space.

Whether you’re restoring a Victorian terrace, fitting out a new build or specifying for a commercial project, every radiator is sectional and built to order. Tell us the section count, finish and valve style you need: we’ll do the rest. Use our radiator configurator to build yours, or build out your radiators by room here.

Popular Cast Iron Radiator Styles

Cast iron radiators play a defining role in how a space looks and feels, not just how it heats. The Paladin range includes traditional, ornate styles with crisp casting detail and period-inspired designs, suited to Victorian terraces, Georgian townhouses and listed properties. The Oxford and Piccadilly are our most decorative models, with deep floral and geometric patterns that work particularly well in hallways, living rooms and more formal spaces where original features are being restored or retained. The Kensington sits in similar territory with a slightly softer profile.

Alongside these, simpler castings with cleaner lines offer a more contemporary take on cast iron. The Bartholomew and Sloane sit comfortably in modern homes, extensions and commercial interiors, where a balance between heritage materials and understated styling is required. Their column profiles let the finish do the talking, particularly in polished or metallic options.

Column configuration shapes both the visual presence and the heating performance of each radiator. A 2-column model provides a slimmer profile for tighter spaces or under windows, while 3-column and 4-column radiators offer greater depth and higher heat output for larger rooms. 6-column and taller multi-column options are often specified for spaces with higher ceilings, where additional output and vertical scale help to proportion the room correctly. The Neo Georgian works well in Edwardian and Arts and Crafts properties, and the compact Churchill is well suited to low bay windows, conservatories and loft conversions where vertical space is limited.

Types of Cast Iron Radiators Explained

Paladin cast iron radiators are most commonly installed as part of a central heating system, connected to a boiler and built to the exact section count the room requires. This is the standard approach for whole-home heating, and suits properties with existing pipework. The sectional construction allows precise sizing across room types, from compact bedrooms and hallways through to larger, open-plan living spaces. These connect to combi boilers, system boilers and conventional setups with no special requirements beyond correct sizing and appropriate valves.

Electric cast iron radiators offer a practical alternative where central heating is unavailable or where independent control is needed. Rather than circulating hot water, they use an integrated heating element with thermostat and frost protection built in. This makes them well suited to loft conversions, garden rooms, bathrooms and outbuildings where extending pipework would be disruptive or impractical. They also allow for room-by-room temperature control without any modification to existing pipework. Read our full guide to how electric cast iron radiators work.

Cast iron is also highly compatible with heat pump systems. Air source and ground source heat pumps operate on slow, low-temperature heating cycles, and cast iron's high thermal mass and large internal water volume make it well suited to storing and releasing heat at lower flow temperatures. This reduces the number of heating cycles the system needs to run and helps maintain consistent temperatures throughout the day. If you're planning a heat pump installation, our team can advise on sizing. Read more about cast iron radiator efficiency and green heating.

Across all configurations, the core principle is the same: precise, long-lasting heat delivered through solid cast iron construction, built to suit the space and the specification.
