That would be up to the person you get to test and notify the job for you.

You should have them in first to assess the job and probably be involved in the design elements.

They would have to be willing to do such a task. Many won't be.

They would have to be registered with a third party notification scheme. Many aren't.

They would have to assess your competence and be satisfied with the standard of work.


Any reason you want to do this apart from the perceived notion of saving a few quid ?

you can certify the job yourself. it's only part pee notification that would possibly be a stumbling block if and when you sell house.

Honest advice
NO
there are a lot of other parameters to take into account, and until it is inspected you and your family are at risk
pay a professional to do it, and rectify any other faults found at the same time
that will be about 1/10th of a CO-OP funeral

OP has ONC Elec. Eng. and classes hin=mself as competent. according to BS 7671, that's sufficient for him to undertake the work. part pee compliance is another matter. don't get me started on the fact that a 5 week course guy who's joined niceic as a domestic installer ( not a qualified spark) can do this work legally, whereas a qualified spark of 40 years experience on top of "proper" qualifications is barred dfrom doing it.

aha I didnt see that
being old technology is not my greatest asset
however a recent weeks work rectifying problems in a property wired by a man who had more electrical qualifications than you could shake a stick at makes me a trifle suspect
thats why I pay a motor engineer to maintain the batmobile, a motorcycle engineer to maintain my Guzzi, and the wife to cook

Yes, but you'll need to get in touch with your 3rd party certifier before starting work. Some NAPIT and STROMA members will be 3rd party certifiers, but not NICEIC or ELECSA members.

Whatever route you take, given this time of social distancing, you don't want to go swopping out your consumer unit and find that there is a fundemental problem that you cannot resolve (even though you deem yourself competent).

Even with no social distancing you'll be hard pressed to get an electrician to come and bail you out. (I'd be laughing down the phone at you)
Given the current set of circumstances you'll be stuffed.

PS do you have a set of calibrated test equipment to allow you to do all of the required tests?

Hi, I know that whoever takes the job on is going to have a hard time pulling the cables out of the back of old fusebox as some monkey back in 78 "stapled" twin and earths to plasterboard woodwork, as seen with snakescope! In view of what you said I shall just free up the cables thru light switch back box opposite, never seen such meaty staples!

we used to use a section of twin and earth as a clip and nail it in, either that or those old thin metal P clips, whack a nail in then fold its over the cable and through the buckle
young people today, they dont know they're born!!

Those are stick on, but with the cable collapse under fire concerns are they not making the metal style again for T&E fixing?

Are you rewiring as well?

The reason for asking is it might just make sense to extend all of the cables using DIN rails or similar to your new CU if there is not enough cable to get to where the CU will have to be located.

This was discussed in another thread, will look.
