— About This Service
Consumer Unit Upgrade
GLR Electrical replaces old fuse boards with modern consumer units designed to meet current BS7671 and Building Regulations. Work includes careful planning, safe isolation, installation of RCDs/MCBs or RCBOs where appropriate, full testing and an electrical compliance certificate. Ideal for older South Bristol terraces, new kitchens, EV charger installs or any home needing safer, more flexible distribution.

Why Choose us for Consumer Unit Upgrade?
Local, reliable workmanship
Operating across Southville, Bedminster and BS3, GLR focuses on punctuality, clear communication and minimal disruption to your home.
Qualified and compliant
Work carried out to BS7671 and Building Regulations by technicians with public and employers' liability cover — installation tested and certified on completion.
Transparent reporting and guarantees
Clear test results and paperwork after the job, manufacturer-backed components and a 6-month workmanship period for reasonable post-installation issues.
Why upgrade? Many older consumer units fitted in Victorian or post-war properties lack modern RCD protection and are ill-equipped for today's loads — EV chargers, modern kitchens and multiple appliances. Upgrading the consumer unit reduces fire risk, improves fault isolation and lets you add circuits safely for extensions, new kitchens or garage conversions.
What GLR does on every upgrade: we assess the existing installation, recommend the correct arrangement of RCDs/MCBs or RCBOs, fit a recognised manufacturer unit with wiring terminations checked to BS7671, carry out full inspection and testing, and provide the appropriate electrical installation certificate and test schedules. We work to Building Regulations, explain any follow-on remedial work highlighted by testing, and leave your consumer unit labelled and easy to use.

Frequently Asked Questions
If your home uses fuses instead of modern MCBs/RCDs, trips incorrectly, frequently blows fuses, or cannot support new appliances like an EV charger, an upgrade is usually recommended. GLR can give quick guidance from photos and follow up with a no-charge site visit to confirm.
