Cast iron radiators ‐ they’re heavy, they leak, they’re a pain to install, right? Not ours.

No Heavy Lifting

When your client chooses a cast iron radiator from Castrads, they are choosing superior craftsmanship and unrivalled customer service. Available in Greater Manchester, Greater London and elsewhere by request, our two‐man delivery service positions the radiator inside the property, placing it in the specified room ready for installation.

Tested. And Tested

We never ship anything without it first undergoing our detailed quality assurance process. Every radiator we make is double-tested and our wall thickness is a guaranteed minimum of 0.1″.

Ready to Roll

When your client selects and orders one of our cast iron radiators, you won’t have to worry about sourcing additional parts.

All of our products are delivered fully fitted with all bushes, sealed and ready to be plumbed in. Our valve tails are self-sealing too, reducing the time you spend on each installation.

And if you’re prepping your client’s property before the arrival of the radiator, we can supply accurate pipe measurements to allow you to fix the pipes in position ahead of time.

If you’d like to get a sense of how one of our radiators might look in the space you’re refurbishing, we’re more than happy to send you sample finishes, and even sample radiators, upon request.

We once sent three sample radiators from Manchester to NYC to assure the correct, totally custom finish was exactly what the client had in mind.
