What pete says about dave's post.
Chaps,
After reading several posts, threads etc about CU changes and what you are responsible for, i thought i would clear a few things up for those that are unsure.
Now, this affects anyone changing a CU to bring an installation up the current standard, which of course is BS7671 2008.
Now, the following are RECOMMENDATIONS and not set it stone, but its what i normally try and do, which can save a lot of time and trouble.
If you have been asked to price and change a CU, for whatever reason, you should ALWAYS carry out a site survey before any costs are discussed.
Now, once onsite consider carrying out the following:
1- Main Earth Bonding.
i) Is main earthing present?
ii) If so, is it adequate?
iii) IF not include this in your quote as this MUST be up to current standards.
2 - Visual Inspection
i) How old does the installation look?
ii) Are there broken accessories?
iii) Is there evidence of any additions or alterations, good or bad?
iv) Ask the client of any known issues or problems in the past.
3 - Quick Basic Check & Tests
i) If convenient, isolate supply and take off the CU cover
ii) Evidence of additions or alterations?
iii) Carry out IR test between Earthing bar & Neutral bar at 250V
If everything looks ok then you are good to go, BUT, whatever happens, make sure you draw up some form of basic contract that highlights the fact that the quote does not include putting anything un-forseen right, and that if there are problems found during or after, then they may need to be rectified at additional cost.
Now, if there are issues with an installation that are not considered unsafe, although not to current BS, (unearthed lighting circuits excluded), you ARE NOT generally required to put these right, although they should be noted on the cert in the correct box.
4 - Certification.
There is a little confusion about what cert should be issued, of course, after a PIR is carried out.
The way i do it is, if i do a CU Change a full installation cert is issued, noting any deviations.
On the same cert any circuit additions or alterations can also be noted, so there is no need to write out multiples.
If you are just altering circuits with no CU change, then a separate minor works must be issued for each circuit altered.
Also, once you have changed a CU, carried out all the tests, you DO NOT become responsible for the entire installation - just the CU change.
This must be noted on the cert & periodic inspection label that MUST be fitted after the change with the words - "CU CHANGE ONLY".
Hope that helps, and if there any E&O's then let me know.
Good luck - As most CU changes need it
just my two cents but i would use an electrical installation condition report rather than installation cert or it looks like you installed itThanks jason brilliant post. My only problem is you would hope everyone on here trading would already do this as to be deemed competent at there job

eic for board and eicr for circuits or are you putting yourself down as the installer of the circuits on the paperwork?

Have a quick look around the installation first, if it looks a bit rough and you don't want to put your name against it then walk. Always tell your customer that you will only proceed with the CU change once you have completed an EICR, if there are any faults you can then quote to repair or rewire and change the CU at the same time, or if there are no faults, you can go ahead with the swap and know there will be no issues later on. Explain this to your customer and if they don't agree to your terms then get out of there. They're either time wasters, want you to do it at foreigner prices or they've something to hide. I've had this rule since I qualified, never fails.
