Consumer Unit Upgrades
A modern consumer unit (fuse board) with RCD/RCBO protection is one of the most important upgrades you can make to your home's electrics. We install replacement boards to current UK wiring standards.
Your consumer unit is the heart of your home's electrical system. Older boards with rewireable fuses or limited RCD protection may not meet current safety standards and can leave circuits — and people — vulnerable to electric shock or fire risk.
A modern board provides individual protection to each circuit, so a fault on one circuit doesn't take down the whole house, and offers proper protection against earth leakage.
Signs your fuse board may need upgrading
- Old style rewireable "fuse wire" fuses
- No RCD (residual current device) protection
- A single RCD covering everything in the house
- Cracks, scorch marks or a burning smell
- Frequent, unexplained tripping
- Preparing for a rewire, extension or EV/solar work

Frequently asked questions
How long does a consumer unit change take?＋
Most straightforward domestic changes are completed in a day, though older or larger installations can take longer once initial testing is done.

Power is only off while the changeover is happening. We plan the work to minimise disruption.
What if my circuits fail the initial tests?＋
We'll pause, explain what's been found, and agree with you how to put it right before continuing.
