Lol, fear not.
I doubt any of you have broken any rules (note, they are only rules, the most they can practicaly do is force you to get the install tested and signed off!). You of cource have an alternative option of having your work tested as part of a 10 year inspection and present the results to building control (who will charge a fee) to sign off and you HAVE then met all the requirements!
Part P is a typical set of naff rules which you can drive a bus through (just like the gas regs!) and to put it simply, you are permitted to carry out small jobs i.e. adding a socket, repair, replacement etc.
And as a certain building control inspector said to me, if you carry out a large number of small jobs you get a large job done.....and you wont have done anything wrong
Just be wary of kitchen and bathroom installs.
True. It's just a little galling, TBH.
On the other hand, my brother decided to have a career change a couple of years back and started working as an electrician. He has been on the road doing jobs ever since, with sole responsibility for all sorts of installations although actually not qualified in anything other than food hygiene. Because he works under the umbrella of a firm of electrical contractors it's under the radar. Some of his colleagues apparently don't even have licences for the works vans they drive.
I have no problem with a few regulations if they guarantee quality for the customer whilst still allowing the competent amateur to do his own work, but, the majority of rules are designed to create work for contractors whilst not impeding the cowboys. Just look at a few "LPGA registered" gas installers' work if you don't believe this.
