Fuse Box Replacement & Consumer Unit Upgrades in Bromley

Fast, professional and fully certified. Serving South East London.

Safe, Certified Consumer Unit Installations by a Qualified Electrician

I carry out fuse box replacement and consumer unit upgrades in Bromley and the surrounding area, and it is one of the most impactful electrical improvements you can make to a property. If your home still has an old-style fuse box — the kind with rewirable ceramic fuses rather than modern circuit breakers — it is almost certainly time for an upgrade. A modern consumer unit provides a dramatically higher level of protection for your home, your family and your appliances than an ageing fuse board can offer.

A modern consumer unit includes RCD and RCBO protection, which monitors the flow of electricity through your circuits and cuts the power in milliseconds if a fault is detected. This protection is not present in older fuse boxes and represents one of the most significant safety improvements you can make to a domestic property. Many insurers look more favourably on properties with modern consumer units, and an upgrade is often required before a mortgage lender will approve a purchase on an older home. The investment is straightforward to justify from both a safety and a practical standpoint.

The upgrade process begins with a thorough assessment of your existing electrical installation. I check your current consumer unit, inspect the condition of your wiring and assess whether any circuits need attention before the new board is installed. Fitting a new consumer unit onto degraded wiring does not solve the underlying problem, and I will never cut corners by doing so. If I identify any issues during the assessment, I discuss them openly and provide a clear price for any additional work required. You will always know exactly what you are agreeing to before any work starts.

On the day of the installation, there will be a period without power while the old consumer unit is disconnected and the new one is wired in. I plan this carefully to keep the interruption as short as possible, typically completing the changeover within a few hours for a standard domestic property. Once the new unit is in place, I carry out a full programme of electrical tests to verify that every circuit is safe before restoring the power. All consumer unit replacements are notified to Building Control under Part P of the Building Regulations. You will receive an official completion certificate — essential for your records and any future property sale in Bromley.
