Cast Iron Radiators
Cast Iron Radiators for Period and Listed Buildings
Cast iron radiators belong in period buildings. They hold heat, radiate it gently and look right against lime plaster, panelled joinery and original fireplaces. Our range covers the patterns found in British houses, schools and public buildings from the 1870s to the 1920s, from plain column radiators to the scrolled Nouveau, Powis and Tredegar.
Every radiator is built to the length you need, from 3 to 30 sections, tested to BS EN 442, rated to 6 bar and guaranteed for 10 years. Choose primer for painting on site or a factory colour, and we will size it properly for a boiler or a heat pump.
The range
The classic plain column radiator of the late Victorian house. Five heights from 353mm to 935mm, 140mm deep, 40.8W to 116.4W per section. The plain pattern conservation officers usually prefer.
From £37.00 a section · See the range
Plain columns in two depths: the 70mm 2 column for halls and passages, and the 221mm 6 column, with the most heat per metre of wall, for heat pumps and short walls.
From £38.30 a section · See the range
The rounded-top radiator of Victorian schools and chapels, in 2 and 3 column, 520mm to 920mm. For schoolrooms, chapels, village halls and their conversions.
From £117.70 a section · See the range
Art Nouveau scrollwork on every section, in 760mm and 954mm heights. A decorative radiator for reception rooms, halls and staircases.
From £135.40 a section · See the range
Our most ornate radiator, named after Powis Castle: rounded tops and deep scrolled relief, 838mm high, 136W per section. For drawing rooms and libraries.
From £221.20 a section · See the range
An ornate three-column radiator named after Tredegar House, 760mm high and 180W per section: the highest-output decorative pattern, for large principal rooms.
From £197.30 a section · See the range
Valves are sold separately: see our Kentwell and Chartwell radiator valve sets. To see each pattern in a period room, visit the radiator gallery.
Cast iron radiators and heat pumps
Many period houses moving to a heat pump need more radiator surface, not less. Radiator outputs are published at ΔT50, which suits a boiler; at the ΔT30 typical of a heat pump a section gives about half its rated output. Cast iron suits heat pumps well: its mass favours long, steady, low-temperature running and gives an even warmth in solid-walled rooms. Every product page shows outputs at both temperatures, and our guide to cast iron radiators and heat pumps in listed buildings works through an example.
Radiators in listed buildings
Listing protects interiors as well as exteriors. Replacing radiators, altering pipe runs or siting a heat pump may need listed building consent, and original radiators may be historic fabric worth keeping. Talk to the conservation officer early. A clear radiator schedule, showing heat losses, patterns, positions and pipe routes, makes the conversation much easier, and we can supply drawings and specification wording to support an application.
What we need from you for a radiator schedule
- Room-by-room heat losses in watts, with the design room temperature
- Flow and return temperatures, or whether a heat pump is planned
- For each position: wall or window width, height to the window board and any dado rail
- Any depth limits, such as narrow halls, shutters or window seats
- Preferred pattern, or the building’s date and listed status
We return the model, section count, length and output at boiler and heat pump temperatures for every room. Read our guide to sizing cast iron radiators for a period room, or download the 2026 cast iron radiator specification guide (PDF) with every pattern, output and a model specification clause.
Frequently asked questions
Which cast iron radiator is right for a period house?
Match the radiator to the date and status of the room. The plain Victorian 4 column suits most Victorian and Edwardian rooms and Georgian interiors where restraint matters; Board School suits schools, chapels and halls; Nouveau, Powis and Tredegar belong in principal rooms.
Do cast iron radiators work with a heat pump?
Yes, if they are sized for the lower water temperature. Outputs are published at ΔT50; at ΔT30 a section gives about half that, so heat pump systems usually need more sections or a deeper pattern such as the Edwardian 6 column.
Do I need listed building consent to replace radiators?
You may. Replacing radiators or altering pipe runs in a listed building can need listed building consent where it affects the building’s character. Speak to the conservation officer early; we can supply drawings and specification wording.
How are your cast iron radiators priced and delivered?
Each radiator is priced by the number of sections, so you pay only for the length you need. Primer finishes are typically dispatched in about 14 days and factory colours in two to three weeks. Delivery is a flat £95 plus VAT per radiator order.
Can you tell me which radiators I need for each room?
Yes. Send us room-by-room heat losses and we will return a radiator schedule with the model, section count, length and output at boiler and heat pump temperatures. If you have no heat losses yet, we can arrange a site survey.
