Hi All Just to clarify there has been two changes to the Regs, 1 The colours for electrical installation were changed in april 2004 and for a period of 3 years you can use either, with certain rules, new installation should use the new colours, Alterations can use either, but you need to put a sticker stating that the installation has been modified and uses combination of new and old. 2. The regs have added a new part called part P (Jan 2005) This effectively means that DIYers are prevented from doing anything but minor works, changing a switch and socket etc. It also means the regs are subject to building regs now, so if your new workshop has got or will need planning permission then you cannot do the wiring as it will need testing and all results will need to be passed to the planning officer as part of the signing off for the new works. The system has also been set up that the person doing the wiring and testing has to be a "competent person" and all test equipment must be in calibration, you cannot do the work and then get someone to sign it off. Just to add I am an electrical engineer who designs Industrial control systems, tests the instalation and signs all the forms, but according to my local planning officer I am not a "Competant Person" and that's with City and guilds for the regs and the Inspection and test certificate, So if its an Industrial installation I can do it, but I can't add a new ring main to my own garage !!!!!!.

If a person was to manage to get hold of some wire in the pre Jan 2005 colours, then no-one would know that the wiring wasn't done before the Jan 2005 cutoff date! Time for obtaining this wire is probably running out rapidly. Also, I don't know how hard/fast/where the dividing line is between temporary and permanent wiring - so if you aren't intending to leave your workshop equipment behind when you move out, the do you really need to leave the wiring, and if you aren't trying to sell the wiring, then it can be temporary - does this allow any kind of exclusions? The only other problem is that your electricity supplier has the right to inspect your wiring/check any ceritificates if you wish to still keep receiving electricity, but I don't know of anyone who has ever been inspected in this way (but it is in the small print). Yours, Rich.
