A Fuse Board Installation in Brentwood You Can Rely On

A fuse board that trips repeatedly, still uses rewireable fuses, or predates modern RCD protection may lack the protection standards required today and should be assessed by a qualified electrician. OJF Electrical and Renewables Ltd carries out fuse board installation in Brentwood and the surrounding Essex area, replacing outdated boards with modern consumer units built to current wiring regulations.

Our engineers are fully qualified and NAPIT-registered, so every fuse board we fit is tested, certified, and signed off in line with BS 7671 requirements, including surge protection as standard with every RCBO consumer unit we install. No shortcuts, no half-finished paperwork.

What a New Consumer Services Unit Gives You

Older fuse boards often mix circuits that have no individual RCD protection, meaning one fault can knock out power to the whole house, or worse, go unnoticed entirely. A modern RCBO consumer unit isolates faults to a single circuit, so a fault in the kitchen won’t leave your whole home in the dark.

Every board we install is metal-clad as standard, correctly labelled, and configured to match your household’s actual circuits rather than a generic layout. We also fit surge protection devices (SPDs) to shield sensitive electronics from voltage spikes based on your supply requirements. Most fuse board replacements in Brentwood are completed within one working day, depending on the condition of your wiring and the number of circuits, with the property left powered by the end of the day and a full Electrical Installation Certificate issued afterwards.

Electrical Services FAQs

How long does a fuse board replacement take in Brentwood?

Most domestic fuse board replacements are completed within one working day, depending on the condition of your wiring and the number of circuits, with your power restored the same day.

How much does a new consumer unit installation cost in Brentwood? 

Pricing depends on the number of circuits, the condition of your existing wiring, and what your installation requires. We carry out an assessment first and confirm the exact cost before any work begins.

Do I need an inspection before booking?

Yes. OJF Electrical first carries out a full Electrical Installation Condition Report (EICR) to assess your existing wiring, circuits, and setup so the quote reflects your property accurately and the installation day runs without issue.

Is a new fuse board really necessary or just recommended?

If you still have a board with rewireable fuses or without RCD protection on all circuits, it is highly recommended that you have it assessed by a qualified electrician. An EICR can also identify whether the existing board or its level of protection requires improvement or remedial work.

Will I lose power during the installation?

Yes, briefly. The supply is isolated while the new board is fitted and tested, and power is restored before we finish up, normally within the same visit.

 Trustindex verifies that the original source of the review is Google. Ollie and the team did a re-wire at the property, which was done very much to our satisfaction. There were a couple of things which weren’t quite right and they have been resolved very promptly. I would us OJF again and would recommend to others.

 Trustindex verifies that the original source of the review is Google. We had the team come install solar panels, battery and an inverter in our home in Chelmsford. They were efficient, did a great job and made everything look good. They were very approachable and the aftercare of the install was excellent. The package they put together was perfect for our needs. Even the scaffolding was put up and taken back down within the week. Can’t recommend these guys enough.

 Trustindex verifies that the original source of the review is Google. Local business, nice people to deal with (Ollie, Erin and Mason), on time, good communication and tidied up afterward.  EV charger fitted neatly, looks great and they dealt with a couple of other electrical bits that needed sorting at the same time.  Happy to recommend.

 Trustindex verifies that the original source of the review is Google. From the first contact to the resolution of the problem all communication was clear and helpful. Olly initially talked me through some "self help" ideas. I was then contacted by his office and an appointment made. Each time I was told what would happen next and when I would be contacted again. Each time they did exactly that.
Olly arrived on time (to the minute!) and as soon as he entered the house, put on shoe covers, without even asking.
The fault with our solar system was located and fixed very quickly and with minimum disruption and the bill was less than I expected.
Top class service. Considerate, thoughtful and dependable. Thoroughly recommend.
