Install one extra double socket to bedroom.

[Martyn Bell]

Am I as a D.I.Y person allowed to connect a spur for one extra double socket to an existing ring main socket in a bedroom? Are there any tests, like measure loop impedance or certificates required for this? Can this be done without the need of a qualified electrician? Do I need to inform anyone?

There s nothing stopping you but please be aware that you don't know if the installation is safe before you start or after

 

[Martyn Bell]

Could I use something like this to test the circuit before and after?

To be honest that won't tell you much BUT would be better than nothing

Yes.

Yes.

Yes.

Do I need to inform anyone?

No.

Anyone is allowed to do any electrical work (in England) but that anyone must do it properly and follow the only law which applies to the work.

Thanks

I notice that under (Do I need to inform anyone?) you answer NO. I have found this thread https://www.mybuilder.com/questions/v/11251/spur-a-new-twin-socket-from-existing-socket which says otherwise. I don't know who to believe.

I don't know who to believe.

Well, I know who I believe. Clue; there is a lot of crap on the page that you linked to, some of it is out of date and some is just wrong.

If you are meaning this bit:

"Firstly before you start you need to register your intent to carry out DIY electrical work with your local authority and pay their part P building regulation consent fee. See links below. If you don't register the works then your effectively breaking the law and could be fined up to £5000."

That is quite simply wrong.

Apart from anything else, the notification procedure is nothing to do with Part P (which is above in its entiriety) but Regulation 12 of The Building Regulations.

This lists the work which must be notified - only three types in England:

The Building Regulations &c. (Amendment) Regulations 2012

These Regulations amend the Building Regulations 2010 (“the Building Regulations”), the Building (Local Authority Charges) Regulations 2010 (“the Charges Regulations”) and the Building (Approved Inspectors etc) Regulations 2010 (“the Approved Inspectors Regulations 2010”).

Quite simply, take with an extremely large pinch of salt the info you hihlighted on mybuilder.
Yes you can do it yourself.
You must be competant enough to do it safely.
That tester you mentioned only shows part of one thing - it looks like it might be OK polarity-wise but not conclusively using that equipment.
Really you should be testing that 1/ the circuit you are adding to is OK and safe to do so and 2/ the the bit you are adding is likewise.
It can only really be done properly by someone competant enough and using the correct test gear (two or more meters or one multi function meter).
However, in practice, many do such additions and do not test. We do not actually find piles of dead bodies littering the streets from such works, or indeed from repairing car brakes etc but there are dangers.
Clint Eastwood said "Each man should know his limitations .
Donald Rumsfeld talked about known knowns, known unknowms and unknown unknowns.
Bear in mind what they said.

On the subject of part P

England use one version (2013)
Wales use another version (2010)
Scotland and Northern Ireland don't have Part P

As long as you live in England what you propose isn't a new circuit or within zones in a bathroom then no notification required

This is a better tester because it gives you a basic earth loop test https://cpc.farnell.com/kewtech/loo...7569&s_kwcid=AL!5616!3!426684131249!!!network}!1876885690054!&gclid=CjwKCAiAqY6tBhAtEiwAHeRopa5n-mWa1A7Wn7Fh_lE0WxTq1V2282l1jVD6VDFHBseZSlxfsGcQGxoCrLQQAvD_BwE

mrrusty - I can not see any mention of Zs in ohms there so I wonder what confirms good eludes to?

"checks the presence of the earth connection, the 107, more importantly, also checks the quality" Hmm , not sure!

a simple 3 light LED/Neon tester gives three lights even if N & E are reversed for a start (or even the E dervived from N via an internal link - I have such a setup in a dedicated test only socket at home to avoid RCD trips) so a physical look might be in order.

I agree that as a "quick ruf test" they have some use though as a better than nowt sort of thing

 

[Martyn Bell]

Thank you all for clearing that up for me, I will get on with the job now.

Or not.

Nope, same version:

That's it. There is no more.

As said above - and ignored - the notification requirements are in separate Building Regulations - Regulation 12 in England and Schedule 4 for Wales.

It's only been eighteen years.

You are probably referring to Approved Document P which is just some guidance that someone wrote.

Less than 1.8ohms according to the manual.
