Hi, wondering if anyone can help? We're doing an extension and loft conversion, and plumber has quoted 29,000 for plumbing including new boiler, vented cylinder, piping to 2 bathrooms, 3 radiators in new upstairs, piping to kitchen, second fix plumbing and wet UFH to new extension (34m2). Does this sound reasonable for home counties areas? Asked him to remove UFH to lower cost, but he says radiators cost even more!
