Clear handover after a consumer unit change

A clear consumer unit handover means sensible labels, a plain English walkthrough and a clear explanation of any paperwork.

Serving Brent, wider NW London, and selected West London postcodes. For consumer unit questions, send your postcode and 2–4 clear photos, including the board with the cover closed.

What you should normally be shown at the end of a managed consumer unit replacement: how the new board is laid out, what the labels mean, what to do if a circuit trips, and how any paperwork is handled if documents follow through registered electrical delivery afterwards.

What this usually means

A good handover should leave the new board easier to understand than the old one, not turn it into another thing you have to guess at.

What a good handover covers

  • The main switch and the overall layout are pointed out clearly.
  • Labels should make sense for real rooms or uses as far as can be confirmed safely on site.
  • You are shown the basics of what to do if a circuit trips, and when to call rather than keep resetting it.
  • Any changes from the old board, or any limits in the older circuit labelling, are explained plainly.

Paperwork and next steps

  • You should know what paperwork is being given now and what may follow through registered electrical delivery afterwards.
  • The explanation should be in plain English, not just a bundle of forms handed over at the door.
  • If testing found wider issues beyond the board change, those should be listed clearly as separate next steps.
  • Clear handover means leaving with fewer questions, not more uncertainty.

What can change the scope

  • Older installations are not always labelled neatly, so some circuits may need careful confirmation rather than guesswork.
  • Hidden damage, poor previous work or wider faults can turn a simple finish into a handover plus a follow-up plan.
  • If that happens, the handover should still stay clear: what is complete, what still needs attention, and why.
