I am a self-builder and I am going to install the hot and cold water system (including radiators) but I need help from a qualified/experienced plumber to design it correctly - for a fee. When installed, I will call an approved boiler installer in order to comply and get the certificate of boiler installation and system commissioning. The communications will be by e-mail with drawings etc as it is not likely that the person who can help me will be local.
Any volunteers or does anybody know someone who can help?
