Part P and house extensions
I am currently planning an extension to the house and whilst I will be getting a builder in to construct the shell I will be undertaking various other jobs myself.
One of the DIY jobs will be the electrical work which I understand would, if undertaken in the existing house, be non-notifiable under Part P by virtue of it only involving extending existing circuits and there being no new circuits, special locations etc. However, given that the extension construction is itself subject to formal sign off from Building Control will this mean that the electrical work within it also be subject to this formality? If so, what options do I have (other than getting an electrician who can self-certify in) to achieve this? Mathew |

Oh for the good old days when the electricity board would send an inspector. -- Old Codger e-mail use reply to field What matters in politics is not what happens, but what you can make people believe has happened.

Some further, albeit cursory, searches makes me think I might actually be okay - in Wiltshire Council's details of charges (http://wiltshire.gov.uk/downloads/6553) it states: --- 3. Electrical works Where electrical work is €œnotifiable€ and is undertaken by an electrician who is not a member of a Part P €œcompetent persons scheme€ a charge of £291.67 + VAT will be made to recover the councils costs in checking this element of the project. --- I am assuming from this that "non-notifiable" work, even if undertaken by 'an electrician who is not a member of a Part P competent persons scheme', would not be subject to any additional costs. Similar wording is contained in their Building Regs Submission form (http://www.wiltshire.gov.uk/wilts-bu...ation-form.pdf) Presumably the extra costs are because the council are unable to perform their own testing given it is arguably more involved than just observation and opinion as per the rest of their checks. If it will end up costing me £291.67 + VAT then I may well be better off just paying an electrician to wire up the few sockets that I'll be adding. |

They've always been *able* to (as they have the last work on Building Control matters) - but most didn't want to as it was outside their comfort zone. |

It's just that this time I have to involve BC for the extension (quite rightly IMHO) but I am worried that I won't get the completion certificate without the electrics being formally tested. I might just change the design so that there's no electrical work whatsoever. The extension of the existing circuits could be done at a later date and, by virtue of them being non-notifiable, not require any sign off. |

The builder extended existing circuits, lighting and power, on my extension a few years ago. The building inspector was told this and there was no problem getting the completion certificate. |

Certain building inspectors may not be so happy. Even the offer of a free punch in the gob does not cheer then up. -- Adam |

That's reassuring; thanks Peter. To be honest it was always my plan to live with the new extension for a while before deciding on the final layout of the new room. This means that the majority of the electrics would likely be delayed anyway and so if I can get the works signed off in that interim period I should be okay anyway. That said, at what point is an extension considered 'complete' for sign-off purposes? Perhaps I'd need to get as far as plasterboarding (and possibly plastering?) given that such components form part of the thermal and fire envelope? |
