Fuse Box Upgrade Haywards Heath

A standard consumer unit replacement in Haywards Heath typically costs £350 to £600, depending on the number of circuits, the type of board (split-load, dual RCD, or full RCBO), and whether any associated work is needed such as earthing upgrades or meter tails replacement. We always give you a fixed written quote before work begins so there are no unexpected extras.

Most consumer unit replacements take 4 to 6 hours. There will be a planned period without power during the installation, usually 2 to 4 hours. We aim to keep this as short as possible, test every circuit before we leave, and issue the completion certificate the same day.

Yes. Consumer unit replacement is notifiable under Part P of the Building Regulations. We notify building control on your behalf and issue the compliance certificate on completion. You'll need it if you ever sell or remortgage, as lenders and conveyancers routinely ask for it.

It depends on your existing board. We check it as part of every EV charger survey. If it's too old, doesn't have enough spare ways, or lacks the right protective devices, we'll recommend an upgrade first. Both jobs can usually be done in a single visit.

A split-load board divides your circuits between two RCDs. If one RCD trips, you lose power to half your home at once. Full RCBO protection gives every circuit its own individual device, so a fault on one circuit only affects that one. RCBO boards cost a bit more but they're much easier to live with and quicker to fault-find when something goes wrong.

Old ceramic fuse wire boards don't provide the RCD protection required by modern wiring regulations, and fuse wire doesn't trip as quickly or reliably as a modern MCB. They're not automatically considered immediately dangerous, but they're not compliant with current standards. We'd always recommend upgrading, especially if you're a landlord (an EICR will almost certainly flag it as a C2) or if you're planning to add any new circuits.
