For an average UK home a consumer unit upgrade is a one-day job. We arrive first thing, isolate the supply, and normally have power fully restored by late afternoon.
Typical timeline
- 8:00 — arrive, run pre-installation checks.
- 9:00 — isolate supply, remove old board.
- 10:00 – 14:00 — fit new consumer unit and re-terminate circuits.
- 14:00 – 16:00 — full test, certificate and demonstration.
When it takes longer
If we find issues that need remediation — poor earthing, damaged cables, borrowed neutrals — we'll pause and talk you through the options before continuing. In rare cases work may extend into a second day.
