How long will the power be off?

The power will be off for most of the working day, usually 6 to 8 hours. We will let you know in advance so you can plan around it.

Do I need a new consumer unit?

If your fuse board does not have RCD protection, uses rewirable fuses, or has been flagged on an EICR, then yes. A modern consumer unit is both safer and a regulatory requirement for many situations.

What is the difference between RCD and RCBO protection?

An RCD protects a group of circuits, so if it trips, several circuits lose power. An RCBO protects each circuit individually, so a fault on one circuit will not affect the others. RCBOs cost more but offer better convenience.

Will you need to do any rewiring?

Usually not. A consumer unit upgrade focuses on the board itself. However, if we find wiring faults during testing, we will let you know what needs attention before proceeding.

Do I get a certificate?

Yes. You will receive an Electrical Installation Certificate and Building Control notification. Keep these safe as you will need them if you sell or let the property.

What Our Customers Say

Power went out at 11pm on a Sunday. Called Capital Electrician and someone was at my door within 45 minutes. Turned out to be a faulty connection in the consumer unit. Fixed on the spot. Could not ask for more.

Ealing

Emergency Electrician

Needed an EICR for my rental flat before the new tenants moved in. Booked for the following week, electrician arrived on time, and I had the certificate emailed to me the same day. Simple and professional.

EICR & Electrical Certificates

Had our 1930s house fully rewired. It was a big job and they were upfront about the disruption, but the team worked tidily and finished a day ahead of schedule. The new consumer unit is a big improvement on the old fuse box.
