How It Works

01

Survey & Fault Finding

We inspect the existing consumer unit, test circuit integrity and identify any legacy issues (old fuses, inadequate earths, nuisance trips).

Specified Upgrade

We recommend the correct consumer unit and protection layout (RCD, RCBO, surge protection) and agree the scope and timescale with you.

03

Install, Test & Certify

Install is completed tidy and to BS 7671. We perform full electrical testing, issue Part P/NAPIT paperwork and leave a clear certificate on completion.

Benefits

Why Choose us for Consumer Unit Upgrades?

Safety & Compliance

Modern RCD/MCB and RCBO protection reduces shock and fire risk and brings installations up to current BS 7671 standards for peace of mind.

Certified Workmanship

NAPIT and Part P registered work with public liability cover and a completion certificate — essential for insurers and future buyers.

Fast, Tidy Service

Same‑day callouts for urgent faults, neat installations and careful site cleanup so disruption is minimised in Derby homes.

What we fit and why it matters. We install premium consumer units from reputable manufacturers such as Schneider Electric, Hager and MK, configured with RCDs, RCBOs and Type B MCBs as required. These devices give selective fault protection, improved discrimination between circuits and optional surge suppression to protect boilers, TVs and EV chargers. Upgrades reduce nuisance trips and greatly improve safety compared with old rewireable fuses or split‑load units.

How CMA Electrics handles your upgrade. After a full survey and fault finding we discuss the recommended layout — number of ways, RCBO distribution, and any earthing or bonding work — and carry out the install to BS 7671. Work is NAPIT and Part P registered, completed with full testing, an electrical installation certificate and clear handover notes. For urgent faults we offer same‑day response across Derby; to arrange an inspection call +44 7952 962048 or email charles.archer@cmaelectrics.co.uk.
