minor works or EIR?

[Welshsparky]

Hi all

wired up a cellar conversion this week, extended the downstairs ring main to add 4 new twin sockets , and also extended the lighting circuit to add 8 new low energy downlights . would i have to give a full report for this or would a minor works for each circuit be ok?

Many thanks

Extensions to circuits is just a MWC, unless you alter the OCPD then a EIC.

No new circuits, so minor works IMO. Check for full continuity on ring, even if not required on cert, as well as R1+R2.

What the others said, MWC

The Minor Works Certificate, is for alterations or additions to a single circuit, including replacing OCPDs.
It's only when a new circuit is installed, or there are alterations to multiple circuits that an EIC is required.
They can't be used for a replacement CU/DB, as multiple circuits are being altered.

Think I may have misunderstood. Did you fit a new CU, PLUS extend the circuits you mentioned? As spin says, if CU change then full EIC.

Surely if you change the OCPD you have to ensure the circuit meets the requirements of the BGB as you are changing the whole characteristics of the circuit.

There are five essential tests that should be conducted when issuing a MWEIC.
Earth continuity, IR, Zs, polarity and if applicable RCD function.
That only leaves R1+R2, which isn't really needed if you've got the Zs.

Fair enough, although I suppose it is down to personal preference.

Its situations like these where a "cut down" EIC would make sense so you can do 1 certificate to cover both jobs.

That said I did use an EIC recently for a similar job.
