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 cast in-house, 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 two decades, 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: cast iron 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 own 10-colour metallic range, our 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.

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 splits broadly into three style groups, each suited to a different type of home.
Traditional cast iron radiators are the cornerstone of the range. Models like the Neo Georgian, offer clean column profiles with the classic proportions associated with Victorian and Edwardian homes. These traditional cast iron radiators sit well in period terraces, Georgian townhouses, new builds designed with heritage cues, and properties where the radiator needs to feel authentic without being overly decorative.
Ornate and Victorian cast iron radiators are our most decorative models. The Oxford and Piccadilly carry deep floral and geometric patterns with crisp casting detail throughout, making them well suited to formal living rooms, hallways and dining rooms in Victorian or Edwardian properties. The Kensington sits in similar territory with a slightly softer profile. If you're restoring original features or specifying for a listed building, these are the Victorian cast iron radiators most often chosen by interior designers and heritage architects.
Modern cast iron radiators bring the material into contemporary homes with simpler castings and cleaner lines. The Bartholomew and Sloane work particularly well in modern extensions, commercial interiors and open-plan spaces where the radiator needs to feel considered rather than ornate. Paired with polished or metallic finishes, these modern cast iron radiators let the material itself do the work without period detailing.
Column configuration shapes both visual presence and heating performance. A 2-column cast iron radiator provides a slimmer profile for tighter spaces or under windows. 3-column and 4-column cast iron radiators offer greater depth and higher heat output for medium to large rooms. 6-column and tall cast iron radiators are specified for high-ceilinged rooms and spaces needing maximum output from limited wall length. The compact Churchill (141 watts / 480 BTUs per section) suits low bay windows, conservatories and loft conversions where vertical space is limited.

Types of cast iron radiators
Wet system (central heating) cast iron radiators are the standard Paladin installation. They connect to your boiler through existing or new pipework and are built to the exact section count the room requires. This suits whole-home heating in properties with functional pipework. The sectional construction allows precise sizing across room types, from compact bedrooms and hallways through to larger, open-plan living spaces. They work with 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 independent control is needed. Rather than circulating hot water, they use an integrated 240V heating element with thermostat and frost protection built in. This makes them well suited to loft conversions, garden rooms, bathrooms, outbuildings and listed buildings where extending pipework would damage historic fabric. They also allow room-by-room temperature control without any modification to existing pipework. Read our full guide to how electric cast iron radiators work.
Cast iron radiators for heat pumps are increasingly specified as the UK transitions away from gas boilers. Air source and ground source heat pumps run at lower flow temperatures (typically 40–55°C) than gas boilers (65–75°C), which means radiators need to transfer more heat at lower water temperatures. Cast iron's high thermal mass, large internal water volume and large surface area make this transfer efficient and consistent, and the slower heat cycles of a heat pump match cast iron's natural heating characteristics. For heat-pump installations, cast iron radiators typically need to be sized larger than the equivalent steel panel: often 1–2 additional sections per radiator. Our team can specify correct sizing based on your heat loss calculations and planned flow temperature. 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.
How much do cast iron radiators cost?
Paladin cast iron radiators are built to order, so final cast iron radiators price depends on your chosen design, column count, section count, finish and valves. The table below gives typical starting prices across our range (inc. VAT).

Steel panel radiators typically have a shorter lifespan than cast iron; a Paladin cast iron radiator is built to last 50 years or more. Factor in reduced boiler cycling thanks to cast iron's heat retention, and the running costs are competitive with any modern radiator type.

FREQUENTLY ASKED QUESTIONSAre cast iron radiators worth it?+−Cast iron radiators are worth it for homeowners who value longevity, heat retention and period aesthetics. A well-maintained cast iron radiator lasts 50–100+ years, retains heat long after the boiler switches off, and suits both period and contemporary interiors. The upfront cost is higher than steel panels, but the lifespan and efficiency benefits offset this over time, especially in heat-pump installations where cast iron's high thermal mass is a genuine performance advantage.What radiator gives off the best heat?+−Cast iron radiators give the most consistent, long-lasting heat because their high thermal mass retains warmth longer than steel or aluminium. Steel panel radiators heat up faster but cool quickly once the boiler cycles off. Cast iron retains heat well after the boiler stops, meaning less temperature fluctuation and fewer boiler cycles. For raw heat-up speed aluminium wins; for sustained warmth and efficiency with modern low-temperature heating systems, cast iron is the best performer.Why do plumbers put radiators under windows?+−Plumbers traditionally place radiators under windows to counteract cold air falling from the glass, creating a convection current that distributes warmth evenly across the room. Older single-glazed windows lost significant heat, and positioning a radiator below neutralised the cold downdraught. With modern double and triple glazing, this is less critical, so cast iron radiators can now be placed anywhere that suits the room layout, though under-window placement still works well for convection and keeps wall space free for furniture.Should I replace my cast iron radiator?+−Replace a cast iron radiator only if it's leaking internally, cracked or corroded beyond repair: most original cast iron radiators can be restored, repainted and returned to service. Paladin manufactures new cast iron radiators for homeowners whose originals have failed, or who want to add period-style radiators to properties that lost them during earlier renovations. A qualified heating engineer can assess whether your existing radiator needs replacement or refurbishment.Are cast iron radiators efficient?+−Yes: cast iron radiators are efficient because they retain heat significantly longer than steel panels, continuing to warm the room after the boiler cycles off. This reduces the number of heating cycles the system runs and helps maintain consistent temperatures. Cast iron takes slightly longer to heat up initially, but the sustained output more than compensates. In heat-pump systems, cast iron's efficiency advantage is even more pronounced thanks to its compatibility with low flow temperatures.Are cast iron radiators compatible with heat pumps?+−Yes: cast iron radiators are particularly well suited to air source and ground source heat pumps. Heat pumps run at lower flow temperatures (typically 40–55°C) than gas boilers, and cast iron's high thermal mass and large internal water volume make it efficient at storing and releasing heat at these lower temperatures. Cast iron radiators may need to be sized larger than equivalent steel panels for heat-pump installations. Our team can advise on correct sizing for low-temperature systems.How long do cast iron radiators last?+−Cast iron radiators last 50 to 100 years or more with basic maintenance. The material is exceptionally durable and built to last, when the system is properly inhibited. Many Victorian cast iron radiators installed over a century ago remain in daily service today. Paladin cast iron radiators carry a 10-year manufacturer's guarantee but routinely outlast several generations of boilers and heating systems.Where can I buy cast iron radiators for sale in the UK?+−Cast iron radiators are available for sale in the UK direct from Paladin, hand-assembled and finished at our Lincolnshire factory and delivered nationwide with a 10-year guarantee. Buying direct from the manufacturer means no middleman margins, full technical support and genuinely bespoke sizing. Use our configurator to build your specification, or contact our team for expert advice.Should I buy new or used cast iron radiators?+−New cast iron radiators are generally better than used cast iron radiators for sale because they offer period styling with modern reliability, guaranteed performance, and no hidden corrosion, leaks or missing sections. Reclaimed radiators can be attractive but often need refurbishment, pressure testing and new gaskets before they're safe to install. Paladin's vintage-style cast iron radiators give you the authentic Victorian and Edwardian look without the risks.What's the difference between vintage and modern cast iron radiators?+−Vintage cast iron radiators are period-authentic designs based on Victorian and Edwardian originals, with ornate detailing and traditional proportions. Modern cast iron radiators use the same material and sectional construction but with simpler castings and cleaner lines suited to contemporary interiors. Paladin manufactures both styles to the same quality standard, so the choice is purely about the look you want.Do you sell tall cast iron radiators?+−Yes: Paladin offers tall cast iron radiators in 6-column and multi-column configurations, suited to rooms with high ceilings, narrow wall sections or spaces needing maximum heat output from limited wall length. Tall cast iron radiators are commonly specified for Victorian hallways, Georgian drawing rooms and double-height extensions.Can I get modern cast iron radiators in different colours?+−Yes: modern cast iron radiators from Paladin are available in our 10-colour metallic range, the full Farrow & Ball and Little Greene partnership palettes, specialist paint effects, hand-polished finishes and bespoke colour-matching. White cast iron radiators, black cast iron radiators and metallic finishes are our most popular choices; we can match virtually any RAL or branded paint colour.Do cast iron radiators work with modern heating systems?+−Yes: cast iron radiators are fully compatible with modern heating systems, including combi boilers, system boilers, conventional boilers and heat pumps. They use standard 1/2-inch BSP connections and work with any modern valve. Correct sizing is the main consideration: cast iron's slower heat-up curve and heat-pump compatibility make it a strong choice for new installations, not just restoration projects.How do I choose the right size cast iron radiator?+−Start with your room's heat loss calculation. Use our BTU calculator to get a target heat output figure based on room dimensions, window type, insulation and external walls. Then divide that figure by the per-section output of your preferred model: each Paladin model has its own BTU output at Delta T 50 and Delta T 30 (for heat pumps). Our team can check your calculation and recommend the right section count.
