— WHY UPGRADE —
Six Reasons to
Upgrade Your Board.
A fuse board upgrade is one of the most cost-effective electrical improvements you can make to a property.
Improved Safety
Old fuse boards lack RCD protection — the technology that cuts power instantly if a fault is detected. A modern board protects your family and your property.
18th Edition Compliant
We install consumer units to the current 18th Edition wiring regulations. Every circuit is correctly rated, labelled, and protected with the right breaker.
Required for Mortgages &
Sales
Many mortgage lenders and home buyers require an up-to-date consumer unit. An upgrade removes a common blocker in property transactions.
Insurance Compliance
Home insurers increasingly require modern consumer units. An upgrade can also reduce your premium — and removes grounds to refuse a claim.
Handles Modern Demand
Old boards weren't designed for today's electrical load. A new consumer unit gives you the capacity for EV chargers, hot tubs, home offices, and more.
Full Documentation
Every board upgrade comes with a certificate issued the same day — registered with your local authority and recognised by insurers, lenders, and letting agents.

— FREQUENTLY ASK QUESTION
Fuse board Questions, Answered.
Everything you need to know before booking your upgrade. Still unsure? Just give us a call.
How long does a fuse board upgrade take?
Most domestic fuse board upgrades are completed within a single day. The power will need to be off for part of the day while we work, but we'll agree a schedule with you in advance so you can plan around it.
How much does a fuse board upgrade cost?
The cost depends on the size of your existing board, the number of circuits, and whether any remedial wiring work is required. We provide a free, fixed quote before any work begins — no hidden extras.
Do I need a fuse board upgrade?
You likely need an upgrade if your board uses rewirable fuses rather than circuit breakers, if it doesn't have RCD protection, if it's tripping frequently, or if an EICR has flagged it as unsatisfactory. We can assess your current board for free.
What is RCD protection and why do I need it?
An RCD (Residual Current Device) monitors the electrical current flowing through a circuit and cuts the power within milliseconds if it detects a fault. It's the primary protection against electric shock and is required in all modern consumer units under current regulations.
Will I get a certificate after the upgrade?
Yes. Every fuse board upgrade comes with a Minor Works Certificate or Electrical Installation Certificate issued on the day of completion. This is registered with your local authority under Part P of the Building Regulations.
