Hi, guess this has been asked before but I can't seem to guess the right search terms. If you are asked to do some work on an existing domestic installation that did at the time, but no longer meets regs (due to changes in regs, not faults), are you supposed to insist on upgrading before you connect? If the customer doesn't want to pay to upgrade do you refuse work? Couple of examples: 1) swapping a light fitting and notice there is no earth - are you allowed just to throw an earth in from the fitting you are working on back to the board and maybe advise on the rest? 2) Old fuse box and you are working on the sockets (adding/relocating) in the kitchen. - can you just do the work (poss add an rcd in line) or would you need to upgrade the box and poss bonding. 3) customer wants outside socket - can you install( within the existing ring) an outside socket with internal rcd protection regardless of how out of date the installation is? (Within reason) or again, would you be quoting for further works before you can do it? If so how often do you have to walk away from work? What happends if you have a regular customer, say a kitchen fitter and you are having to constantly tell his customers its going to cost more? Could you point me to the relevant regs. Thanks in advance.
