Upgrade an old fuse box with a consumer unit replacement in Oxford. We fit modern units with RCD protection, test every circuit and give you an Electrical Installation Certificate.
Old fuse boxes with rewireable fuses or a plastic case lack the protection modern homes need. A new consumer unit has RCDs or RCBOs that cut the power in a fraction of a second if someone touches a live part. That can be the difference between a small shock and a serious injury.
More Information
Current rules require consumer units in homes to have a non-combustible enclosure, which in practice means metal. Most new units also include surge protection, which helps guard TVs, computers and boilers against voltage spikes. We explain what your home needs and fit a unit that meets the 18th Edition rules.
Before fitting a new unit, we test the existing circuits. Faults that an old fuse box ignored can make a new RCD trip, so it is better to find them first. Once the unit is fitted, we test every circuit again, label the board clearly and give you a certificate for your records.
Most consumer unit replacements in Oxford take around half a day to a full day. The power will be off for most of that time. If testing finds faults on any circuits, those may need fixing before the new unit can be switched on, and we will talk you through this first.
You may need one if you still have a fuse box with wire fuses, a plastic unit, or no RCD protection. Regular tripping or a board that looks damaged are other signs. An electrician can usually tell you after a quick look, and an EICR will confirm whether an upgrade is needed.
Yes. Fitting a new consumer unit is notifiable work, so it must be tested and certified. When we finish, you get an Electrical Installation Certificate showing the test results for every circuit. Keep it with your house documents, as buyers and their solicitors often ask to see it when you sell.
