Signature Collection
Our core range of popular neutrals and monochrome finishes, developed especially for cast iron.
We have refined our painting process over the years ensuring the finish is hard-wearing and stays looking great.
Each radiator is dip primed and cured with infra-red, then dipped and cured again. After priming, radiators get two coats of hard-wearing two-pack paint, again with infra-red curing in between.

Bare Metals
Bare Metal Collection
Brilliant, lustrous finishes produced by hand using lacquers and specialist polishing techniques.
We begin by tumbling the cast iron sections for 10 hours in a giant drum filled with ceramic pebbles. The sections are then tumbled for a further 8 hours with small porcelain beads and water.
Powdered porcelain from the beads makes a paste with the water which gives a high shine to the surface of the iron.
We then use layers of primer and tinted lacquers to create deep colours that allow the lustre of the metal to show through.
Polished by hand
For the polished finishes as well as Natural Brass and Aged Gold, the process is entirely manual. Each section is carefully polished against a spinning wheel through 12 grades of increasingly fine abrasive to achieve the various effects. They are then lacquered to complete the finish.

Branded Paints
Make it a Match
For a seamless drench or a vibrant pop, choose your colours from our favourite paint collections.
We use genuine branded paints under licence from Little Greene, Farrow & Ball and Benjamin Moore. Radiators are finished with the same dip prime and painting process as for our Signature Collection finishes for intense colour and a tough, long-lasting finish.
We can’t offer cast iron samples of the branded paints because there are so many to choose from but follow us on Instagram to see our radiators in their sublime colours. For colour cards and plenty more detail on their paints head to the retailers’ websites. We don’t list every single branded paint finish online. If there’s something you’d like, get in touch.
