Commercial-grade consumer unit replacement to current BS 7671 standards, including RCBO protection on final circuits.
Most upgrades are completed within a single day, with power restored circuit by circuit as work finishes.
Individual circuit protection rather than a single RCD covering everything — a nuisance trip on one circuit doesn't take out the rest.
Full certification on completion, old unit removed and disposed of responsibly.
Older plastic-enclosure boards are often flagged on an EICR even if functioning — current guidance favours metal enclosures for fire safety.
Circuits are typically restored progressively through the day rather than all being off for the full duration.
An outdated board can be flagged by insurers; an upgrade with current certification usually resolves that.
