Frequently asked questions

Buy a boiler. Replace your radiators, too.

Add up to 10 like-for-like radiators when choosing your boiler and get a free TRV on each one to help you improve the efficiency of your heating system. We’ll install them during your boiler installation. We can only fit new radiators in place of existing ones, not in new locations.
