Our radiators are hand assembled so we can’t give 100% accurate pipe centre measurements before they've been made. Let us know when placing an order if your plumber is planning to lay pipes before it arrives and we’ll send you the exact measurements usually within 72 hours of an order being placed. Your plumber can then drill holes in the floor and position the pipework with absolute confidence.

Installing cast iron radiators

We supply all our radiators with 1/2” BSP connections to pair with all of our valves and most valves available elsewhere too. We can provide any valve configuration but as standard we’ll always fit them bottom opposite ends (BOE).

Our radiators are sold in over 60 finishes.
