Electrical Certification
We'll be having some building work done soon which will involve some new wiring and a new consumer unit. What's the story with part P etc.
when only part of a house is rewired? Do we just get certificates for the new circuits or do they have to test and upgrade the rest?
Thanks
Stu

My understanding is that if a new CU is fitted then the entire house should really be tested... and if it does not meet the minimum standards then
some rewiring might be required. Your spark should be able to explain the possibilities.
When I had my extension put up the builder (who was a total tool) was going to do the electrical testing as he was NAPIT registered....that would have
been sent to the council building control who would issue me with a completion certificate... He buggered off before the job was finished so that
never happened.
However, a quick call to the building control guys and they sent up their inspector. He tried a couple of light switches...looked at the new CU and
signed the paperwork.. no tests involved.. :s

If you are fitting a new consumer unit then all circuits effected should be tested, new or otherwise!
You can do electrical installations on a building notice but please don't unless you are electrically competent to do so! You will need a few
hundred pounds worth of test equipment too!

I wasn't planning on doing it myself despite being a qualified [many years ago] sparky! I really just wanted to get an idea of what to expect
given that there will be quite a bit of additional wiring being done as part of the building work, and whether there would be likely to be additional
work needed to bring the old wiring up to 17th edition standards.
Thanks for the replies!

Changing a consumer, installing a new circuit or any work to the kitchen or bathroom all require a part p certificate. In addition all electrical work
should be covered by an electrical installation certificate from your electrical contractor.
Part p is a very very basic certificate it came in as a way of stopping the cowboy kitchen and bathroom fitters. All it did however is make them
cheaper as they still don't issue them and the building inspectors generally don't have a clue with electrics. The only people who
regularly issue them is genuine contracting companies like mine who can be audited.
Look on the Niceic web site and choose an approved contractor from there.

Before changing a consumer unit, they should test and inspect the existing circuits, since if they are not safe then they cannot reconnect them, and
this is obviously no good to the customer. Assuming they all check out ok (no guarantee at all of that, esp if diyers have been in!), they can
proceed. I would expect all results to be recorded on a full electrical installation certificate, and if registered properly with a part p scheme
provider (niceic, elecsa, napit etc), then you get confirmation through the post. Elecsa, who my spark uses, send confirmation out immediately if you
register a job online.
If getting a board changed, it might well involve some fault finding on existing circuits - in the past we've had to replace whole circuits if
they were really bad. Thats why you have to tell the customer before you pass the point of no return, to make sure you get paid for additional work.
