    Hi All,

    Sorry if I have misunderstood this but I need to extend my cooker cable due to it moving to a new location in another room.

    From what I understand from reading in the part P regulations as it is altering an existing circuit in a non specialised location it is non notifiable.

    However if the cooker cable is fully replace from the CU, does this then become a "new circuit" and notifiable or as the MCB and cable run and everything is already there is it sill altering an existing circuit?

    So my questions are:
    1) is extending the current cable with a 60A JB notifiable?
    2) is replacing the full cable notifiable?

    P.S. I'm not intending to do much if any of the work myself I just wanted to know the in's and out's of Part P in a little more detail before getting quotes etc...

    Not notifiable.

    As Roger says, no and no.

    Ideally replace the whole cable, but as long as the JB is either maintenance free or accessible it is fine.

    Kind regards

    If you are installing it behind plaster though, it will have to be RCD protected. I think its just lighting circuits that now need RCD'ing if they are in trunking or surface isn't it?

    I am about to do the same thing and had the same question. From what I have read elsewhere even if work is not notifiable does it not have to (legally under Part P) be tested and certified?

    I am simply extending existing 6mm using a 60A wall mounted junction box to a new cooker switch and outlet (chased in to plaster). I will also swap the existing 32A MCB with a 32A RCBO.

    All simple stuff but does it have to be tested and certified?

    I suspect that part means it does... but I'm not a pro, DIY.

    It is quite simple really.

    All work in domestic premises come under the scope of Part P
    All work within the scope of Part P must be carried out to the requirements of the current wiring regulations BS7671:2018
    The current wiring regulations require that any work is inspected and tested and were necessary a MWC(Minor Works Certificate) or an EIC(Electrical Installation Certificate) issued by the designer/installer/tester on completion of the work.

    In addition to this

    Some work is Notifiable to the LABC(Local Authority Building Control).
    Notifiable work must be notified to the LABC before it begins unless the work is being completed by
    A - A person registered on the CPC (Competent Persons Scheme) - some call this being "Part P registered"
    B - being inspected by a Third Party Installer.

    So, although it is not 'illegal' to do a bit of work on your own home it is unlikely unless you have the test equipment you will be able to meet the requirements of Part P.

    Millions of folk have ignored this for years - the choice is yours.

    Thanks Comlec. Where I am still confused is the statement that all work comes under the scope of part P. There are some items listed that are "not notifiable" such as changing a light fitting, or replacing a socket front. But my confusion is: do those jobs still require inspection/test certification?

    All electrical work should be inspected and tested according to the requirements of BS7671, (the IET Wiring Regulations,) by a competent person and an appropriate Certificate issued for the work.

    That may be a Minor Electrical Works Certificate for a job such as you propose, or an Electrical Installation Certificate for larger installation work.

    Kind regards

    Thanks, that clarifies it totally!

    Am I right in thinking that a sparks is likely to be loathe to certify DIY work? Makes sense as it is his name on the cert.

    If you find one that will certify 3rd party work BEFORE you start, discuss the job with him, he will tell you when he wants to inspect and when he wants to test. You must then inform him at the pre-arranged inspection points and he will look at how the work is progressing. He will then carry out the final testing BEFORE you make the circuit live and issue the appropriate certificate.

    Shouldn’t need to be a ‘Third Party Inspector’, as the work doesn’t require notification.
    Any electrician with an MFT should be able to either issue a certificate, or guide someone through the process.
    It’s just a question of finding someone willing.
