Most fuseboard work in Bexhill on Sea is swapping something old for something that actually protects the house. The town is full of 1930s semis, bungalows and purpose built flats where the board on the wall is either the original or a replacement fitted decades ago. If yours has porcelain fuse holders with wire in them, or one big switch and no test button anywhere, it is doing far less than a modern unit does. We fit consumer units right across Bexhill, in Sidley, Little Common, Cooden, Collington and Pebsham, and we are 3.7 miles away in St Leonards so we are on site early. Here is what the job really involves, and what happens if the tests throw something up.
Why old Bexhill boards get replaced
Two reasons come up again and again. The first is rewireable fuses. A wire fuse will eventually blow on an overload, but it does nothing at all to protect a person who touches a live conductor. The second is a complete lack of RCD protection, which is the device that cuts the supply in a fraction of a second when current leaks to earth. Older Bexhill houses also tend to have had circuits bolted on over the years, a shower here, an outside socket there, until the board has no spare ways and the meter tails are undersized for what is hanging off them. At that point a new unit is the sensible fix, not another fuse wire.
What the day actually looks like
We agree a start time and tell you when the power will be off, so you can plan around the fridge, the freezer and anything medical. First we test the existing circuits to make sure the wiring is fit to be put on a new board. Then the old unit comes off, the new one goes on, and every circuit is re terminated and labelled properly so the next person can read it. After that comes the testing, circuit by circuit, and that is the part people underestimate. You get an installation certificate at the end and the work is notified to Building Control under Part P, because a consumer unit change is notifiable work.
When the tests find something underneath
This is the honest part. A new board is far more sensitive than the one it replaced, so it finds faults the old one quietly tolerated. The usual ones in older Bexhill housing are a lighting circuit with no earth at the switches, a borrowed neutral between two circuits, insulation resistance dropping on perished rubber cable, or main bonding missing from the gas and water. That is why we test before we fit rather than after. If something turns up, we tell you what it is, what it will take to put right, and whether it has to be done now or can wait. Nothing gets buried in the invoice.
Flats, storage heaters and off peak supplies
A lot of Bexhill flats are all electric, with no gas at all, and heat through storage heaters on an off peak tariff. That often means two meters and sometimes a second board handling the off peak circuits, which changes the job. Retirement blocks add another layer, because the incoming supply and the meter cupboard sit in the communal hallway and belong to the building rather than to you. We work out who has to give access before we book anything in, and where a managing agent is involved we deal with them direct so the resident is not stuck in the middle of it.
Frequently Asked Questions
Q: What does a modern consumer unit give me that my old fuse box does not?
A: Protection for people, not just for cables. A modern unit uses RCD or RCBO protection that disconnects in a fraction of a second if current starts leaking to earth, which is what protects someone drilling into a cable or touching a faulty appliance. It can also carry surge protection for your electronics and, on some circuits, arc fault detection. A rewire fuse does none of that. It only reacts to overload, and slowly.
Q: Do I need a full rewire before I can have a new fuseboard?
A: Usually not. Plenty of Bexhill houses have sound cabling and simply have an obsolete board on the end of it. What matters is whether the existing circuits pass the tests, which is why we test first. If they do, the board goes on and that is that. If the tests show perished cable or a lighting circuit with no earth, we will tell you before we commit to fitting, because putting a modern board on failing wiring just moves the problem.
Q: Is a fuseboard change notifiable, and what paperwork do I get?
A: Yes. Replacing a consumer unit is notifiable work under Part P of the building regulations, so it has to be recorded properly. You get an Electrical Installation Certificate showing the test results for every circuit, and the work is notified to Building Control. Keep that certificate somewhere safe. It gets asked for when you sell the house, when you remortgage, and by your insurer if you ever need to make a claim involving the electrics.
Q: Can you fit a board now that will take an EV charger or solar later?
A: Yes, and it is worth saying so at the quote stage. Bungalows and houses with off street parking around Little Common and Cooden are exactly the sort of property where a charger gets added a couple of years down the line. We can size the unit and leave spare ways so the charger or a solar circuit can be added without touching the board again. It costs very little extra when the unit is being changed anyway.
