New extension to existing wiring

[Foxyspark]

Just been asked to quote to wire a new kitchen extension. I realise that the new extension must conform to the 18th IEE regs. The existing wiring in the remainder of the building has the sockets lower that the stated 450mm and the light switches are higher than 1200mm. Do these have to be re positioned and rewired?

If the wiring standards comply when they were put in then there is no need to update as long as anything you touch or fit is in accord to 18th regs

simple answer is NO. as long as your new works comlpy with current regs. e.g. RCDs where needed and confirmation of adequate earthing/bonding.

Under regs it is fine as long as the original wiring can carry the new load safely, that it is earthed to current requirements and that the cross bonding is satisfactory. This only takes a few tests, and I expect you would know how.

Thanks alban, that's what I was hoping. The owner has recently bought the property and there was no electrical certificate available with the purchase. He would now like to have a test certificate for the complete installation after the extension is finished. Can the installation now be certificated to different standards?

you can firsrt do a EIC for any work you do. then you could do a EICR for thr whole installation.

once you have finished the job and done all the checks on the old and new stuff including eath bonding as barnincks rightly says then that is fine
you should be able to get a certificate from whoever installed it or ask for a reprint from the appropriate person

I believe it will be very difficult to find the appropriate person or who carried out the initial installation, even if a cert was ever issued .
