Totally agree with danny pipe , if the builder is giving you regular work then you be stupid to do the dirty behind his back every five mins . Come to an arrangement for the boiler upgrades and if your both happy he can price accordingly . Also if you need a builder to do work for you then its a feather in your cap as well .Interested to know why he's getting boiler changes tho is he advertising for them because if he is and no gsr its classed as illegal works and they will chase him .
