Frequently Asked Questions
How much does a fuse board upgrade cost in Devon?
A consumer unit upgrade in Devon starts from £499 plus VAT for a standard single-phase board. Three-phase board changes start from £1,500 plus VAT. The final price depends on the number of circuits and any additional work required.
How long does a consumer unit upgrade take?
Most consumer unit upgrades are completed in 4-6 hours (half a day). During this time, the power will need to be off. We can work around your schedule and ensure essential power is restored as quickly as possible.
Do I need to upgrade my fuse board?
You should consider upgrading if: your fuse box is over 25 years old, you have rewireable fuses instead of MCBs, there's no RCD protection, you're experiencing frequent trips, or you're adding circuits for things like EV chargers.
What's the difference between a fuse box and consumer unit?
A consumer unit is the modern equivalent of a fuse box. It contains MCBs (miniature circuit breakers) instead of fuses, and RCDs for additional safety. The terms are often used interchangeably, but modern consumer units offer superior protection.
Will I need building control sign-off?
Yes, consumer unit work requires Part P notification. As CHAS approved electricians, we can self-certify our work and issue the compliance certificate directly, saving you time and the cost of separate building control.
