Where notification or certification matter, registered electrical delivery keeps installation, testing and handover clear.

Certification usually matters when the consumer unit is being replaced, a report has asked for evidence, or someone needs to know whether notifiable work will be handled correctly. The useful first step is to confirm what paperwork is being asked for and whether the board condition supports replacement planning.
Key point: if the real question is whether an already-finished board change can simply be “certified later”, that needs its own check. It is much better to sort the scope before the work starts than try to repair missing paperwork afterwards.
Send a clear board photo, your postcode and the reason the paperwork is being asked for. I’ll tell you whether this looks like a consumer unit replacement question, a wider condition issue, or registered electrical delivery that needs explaining first.
