How Much Do Cast Iron Radiators Cost? A Straight-Talking UK Price Guide

Cast iron radiators cost more than standard panel radiators. Worth saying upfront. But the gap is smaller than most people think, and when you factor in how long cast iron lasts, the cost per year looks very different.

This guide covers Paladin cast iron radiator prices, what moves the cost and which models suit each budget. Whether you want a ballpark figure or a proper price list to plan around, here’s what you need to know.

Four things drive the price: sections, columns, finish and whether it’s a standard or bespoke order.

More sections mean more heat output and a wider radiator. More columns mean greater depth and higher BTU per section. Both add to the cost. A standard painted finish is the most affordable route. Metallic effects, polished finishes and colour-matched paint all add to the bill, but they make a real difference to the finished look.

Electric models carry a premium over hot water versions. They include an internal heating element and don’t need a plumber, which offsets some of the installation cost.

These are estimates based on a typical Paladin radiator at a standard finish. Prices vary depending on the model, number of sections and any finish upgrades. Use the radiator configurator for a live price on any model.  

Prices are per radiator and exclude valves, accessories and delivery. A basic valve set typically adds £50 to £150 depending on the finish you choose.  

Every Paladin radiator is priced by section, so the total depends on how many sections your room needs. The table below gives you a general sense of where each model sits in the range. Actual prices vary with section count, finish and any bespoke options. Use the radiator configurator for a quote on any model.  

Entry level models are a good starting point for smaller rooms or tighter budgets. Mid range covers the bulk of the range and most room types. Premium models tend to be larger, taller or more detailed, and work best as statement pieces in bigger spaces. 

This depends on what you’re comparing them to.

Against a standard panel radiator, cast iron is more expensive to buy. But cast iron lasts decades. A panel radiator might need replacing in 10 to 15 years. Cast iron also retains heat longer after the boiler switches off, which can reduce how hard your heating system needs to work. Over 30 or 40 years of ownership, the cost per year looks very different.

There’s also the design value. In a period property, a traditional renovation or a room where the radiator is part of the look rather than hidden behind a cover, cast iron does something a panel radiator simply can’t. That’s harder to put a number on, but it’s real.

So: worth it? For the right room and the right project, yes.

Where do Paladin cast iron radiators sit in the UK market?

Paladin radiators sit in the mid to premium bracket for new cast iron radiators in the UK. The price reflects dedicated cast iron casting, hand finishing in Lincolnshire and a guarantee.

Mass-produced radiators from European foundries are cheaper per section. But they typically have less definition in the casting detail and no bespoke finish options. We’re the only cast iron radiator manufacturer with our own dedicated foundry producing exclusively for our range. That matters for quality consistency, particularly on ornate models where sharp mould definition is visible in the finished product.

If you want the best price on cast iron radiators without sacrificing quality, we’d always recommend getting a few quotes and comparing on a like-for-like basis. Section count, column depth and finish all vary between suppliers, so a lower headline price doesn’t always mean a lower cost once you match the spec.

Not all cast iron radiators are traditional in style. The Paladin range includes models that suit contemporary interiors as much as period ones.

The Sloane and Gatsby have cleaner profiles with less ornate detailing, which works well in modern homes. The Louis sits somewhere in between: a bit of period character but nothing that looks out of place in a newer build.

Modern cast iron radiators in the UK typically sit in the same price range as traditional models. The style doesn’t change the cost. What changes the cost is size, section count and finish.  

A cast iron radiator under £500 is achievable for smaller rooms. The key variable is how many sections you need, and that depends on room size and insulation.

A small bedroom or hallway with modest heat demand might need six to eight sections of a 2-column model. That comfortably fits a £500 budget at standard finish.

The Neo Georgian is a natural starting point. Clean lines, traditional column profile, and it suits period and modern homes without trying too hard. The Oxford is worth a look if you want a bit more detail in the casting.

Use the heat calculator before you budget. It tells you the section count you actually need rather than leaving you guessing.

Models to consider under £500

Victorian living rooms typically have higher ceilings and more heat loss than modern rooms. You’ll need more sections or a higher-column radiator. A 4-column model at eight to ten sections often does it, and several Paladin models land under £800 at that spec.

The Kensington is the natural fit. It has some of the most detailed casting in the range, which sits well in a late-Victorian interior. The Victoriana is another strong option: the 3-column version gives good heat output without the depth of a 4-column.

Got a chimney breast? Two smaller radiators either side often heat the room more evenly than one large radiator on a single wall. Two modest-spec models can come in under £800 total.

Models to consider under £800

A budget of £1,500 opens up the full Paladin colour and finish range. Standard colours including black, white, grey, anthracite and cream sit within the base price. Metallic effects like bronze, gold and silver carry a premium, as do hand polishing and the bespoke colour match service.

The Farrow & Ball partnership lets you specify any colour from their range. Little Greene is also available. Both work well on renovation projects where the radiator needs to match existing paint or joinery.

At this budget you can typically get a large radiator in a statement finish, or two mid-sized radiators in a standard colour. The Clarendon and Churchill both work as focal-point radiators in larger rooms where the finish does real decorative work

Models to consider under £1,500 with custom finishes  

I need a high-end radiator for a bathroom with custom colour matching under £1,500

Bathrooms are where cast iron tends to justify its price most convincingly. It handles moisture well, retains heat after the heating goes off and makes a genuine visual impact in a smaller space.

For custom colour matching, the bespoke service lets you specify any RAL or BS colour. The Bartholomew works well in bathrooms: compact depth and an understated profile that doesn’t overwhelm the room. For something with more casting detail, the Pimlico reads well against tiled walls.

A mid-sized bathroom radiator with a bespoke colour match typically sits between £600 and £1,200, leaving comfortable headroom within a £1,500 budget once you add valves and accessories.

Are vintage or antique cast iron radiators worth buying?

Antique cast iron radiators can look great. But they come with real unknowns: internal condition, no warranty and no guaranteed BTU output. Many need re-sectioning, re-sealing and re-finishing before they’re safe to use, which adds significant cost on top of the purchase price.

Reclaimed cast iron radiators typically start from around £50 per section at a reclamation yard. Once restoration costs are factored in, a new Paladin radiator often works out comparable in total spend, with a guarantee and known heat output.

Buying to resell? Antique cast iron holds value reasonably well. Buying to heat a room? New is almost always the smarter choice.

If you’ve come across the term ‘baseboard radiators’ while searching for cast iron heating, it’s primarily an American term for what we’d call skirting or low-level radiators in the UK.

British cast iron radiators are priced per section rather than per foot. The Paladin low-level range includes compact models suited to rooms where a full-height radiator won’t work. Pricing follows the same structure as the rest of the range: section count, column depth and finish.

What’s the best way to get a price for a Paladin cast iron radiator?

The most accurate route is the radiator configurator. Select the model, number of sections, finish and any accessories, and the price updates in real time. It is built for multi-room planning and lets you map each space before getting a combined quote.
