Boiler man says it's not him, flooring guy says it isn't him either and the builder doesn't seem very interested!
Also, does anyone know how much roughly we might expect to pay, and is it worth it? Area is about 15 by 24 feet. It's low priority compared with other things we need to do - some structural work and damp proofing etc - so we might have to stick to radiators if it's wildly expensive. I'd love it though, especially as we have various alcoves that make radiator siting a bit awkward. Thanks!
