why would i want to do that,the problem is trying t find one that gives seasonable quotes,i have had one already who quoted ÂŁ20 per switch to change chrome light switches to plain white and i wanted 5 done.
Scott, here's a rough guide for you.
Buy a multi function tester (allow aprox ÂŁ500 for this). Carry out the usual IR tests at 500v L-N, L-E, N-E. Once you are happy with this, carry out your R1+R2 test and Zs to confirm your existing installation is satisfactory.
Ensure your lighting circuit is covered by RCD and carry out the necessary tests required, x1/2, x1, x5 / 180deg etc.
Ensure bonding to gas and water is satisfactory.
If all these tests prove to be successful and you have RCD or RCBO protection to the lighting in your bathroom, your next step is to notify the Local Authority Building Control of your intension. They will then carry out an assessment of the work required, your test equipment and your electrical experience. (Allow aprox ÂŁ250 for this)
OK, now you’re ready to start.....
Carry out the work in accordance with BS 7671 paying particular attention to bathroom zones, IP65 ratings, loadings, voltage drops etc then design your lighting accordingly.
Carry out the work yourself (remembering accessibility of all connections)
When installation is completed, again carry out all the necessary tests required (IR, R1+R2, Zs, RCD etc) and make a note of them.
Issue an electrical installation certificate and advise building control of completion of work. They will then re-attend and confirm your test results and issue you a certificate to confirm the work has been carried out in accordance with BS 7671.
Please make sure you keep both these certificates in a safe place as when you come to sell the house, your solicitor will need both. Also should any problems arise with your installation, for instance a fire was to happen, you’ll also need to provide these two certificates to your insurance company or your home may not be covered.
Whatever you do, do not pay a time served, fully qualified and insured electrician to carry out the work for you as they are all there just to rip you off.
Hope this helps,
Best regards,
