Optima Electrical replaces old fuse boxes and upgrades consumer units for homes and landlord properties across Leeds. NICEIC-approved, fully certified, and compliant with the latest BS 7671 wiring regulations.
If your fuse box still has rewirable fuses, a plastic casing, or no RCD protection, it is not meeting current safety standards. We replace it with a modern consumer unit that protects your home properly.
A consumer unit is the modern replacement for what most people still call a fuse box. It is the central point where your electricity supply is distributed to every circuit in your home — lights, sockets, cooker, shower, and anything else connected.
We upgrade old units across all areas of Leeds, from Headingley and Chapel Allerton to Morley, Garforth, and Rothwell. Every installation is carried out by NICEIC-approved electricians and certified to current regulations.
The most common trigger is an EICR inspection that flags your consumer unit as C1 (danger present) or C2 (potentially dangerous). If your report comes back with either code on the fuse box, an upgrade is not optional — it is a safety requirement.
Other signs you need a replacement include:
Landlords have a legal obligation to ensure rental properties have a satisfactory electrical safety report every five years. A failed consumer unit is one of the most common reasons for an unsatisfactory EICR.
Every consumer unit we fit is a metal enclosure, as required by the 18th Edition wiring regulations. We install RCD or RCBO protection on all circuits, providing automatic disconnection within milliseconds if a fault is detected.
We also fit surge protection devices (SPDs) in line with current Amendment 2 requirements, helping protect your appliances from voltage spikes.
All circuits are clearly labelled and identified. You receive a full Electrical Installation Certificate on completion, and we notify Building Control on your behalf.
We start with a free assessment of your current fuse box and wiring. You will receive a clear, written quote with no hidden costs.
Installation typically takes around half a day for a straightforward replacement. Your power will need to be switched off for several hours during the work — we will confirm the exact timeframe in advance so you can plan around it.
If your wiring is also outdated, we may recommend a partial or full house rewire at the same time. We will always be clear about what is necessary and what is not.
