Anyone know how much it would cost to complete all the plumbing to a new house from scratch. Including, 2 bathrooms, kitchen, all central heating to all rooms including 5 bedrooms. Also to include fitting and installing a cooker and boiler to run on oil (no gas to the property) including supplying and installing the gas tank. Rough prices really helpful thanks Can I add that I am capable of doing this myself but I do not have the time. Additionally this is in a house that I am planning to sell on when finished, it needs to be all professionally done. Anything I do would have teething problems as I am not an experienced professional. I am not going to do it myself.
