Fuse box replacement - what do they do?

Jamesyboyjim · 26 Sep 2017 at 15:13

Hi all, we have recently bought our first home and have been going through the process of getting it up to scratch, a few people who have either done some work for us or have quoted or have mentioned how old the fuse box is, we have decided to get it changed so have a sparky coming out to do it beginning of October.

What exactly is the process? reason I ask is we have had a new boiler installed but it has run into an issue, the electrics in the airing cupboard that used to power the old immersion heater that was going to be used for the boiler appear to be dead. Our boiler installer insists when we get the new fuse box the electrician will make it live as part of the fuse box change and he'll come back and finish the boiler setup (haven't paid him yet)

Does this sound right or is a fuse box change literally a swap job? Or does the sparky have to figure out what is what and liven anything up I might need / take out anything redundant. My missus has arranged this or I would have asked him at the time.

Just worried now I'll have to pay extra to get electricity up to the airing cupboard even though there is wiring there.

our plumber said it was live when he removed the old immersion so seems weird that its now dead. We did have an issue with one of the circuits in the house (accidentally tripped the 13a sockets touching two live wires with a screw driver, wasn't me who did it but a mistake only made once I'm sure!) but it should have been on a different circuit I would have thought. Is it possible that I've also tripped the power for the immersion somehow?

What type of board do you currently have?

No idea on any actual model numbers. Something old and yellowed over time with little black switches and a big red one to do all the mains. Last serviced in 2008 and very very old. I cant find any images on google.

When I had my old tank with immersion heater removed and combi boiler installed, they used the same connection to power the combi that originally was used to power the immersion. 15A on it's own dedicated fuse in my old skool wire fuse box.

Well that's what they were going to use but they couldn't get any life out of the socket when connecting the combi to it. The plumber said it was live when he removed the old immersion but not when he hooked up the combi. My missus stupidly said it might be our fault so now the plumber has said he'll do it when we get it sorted. She should have played dumb and said it should work, what have you done.

Do you have any switches anywhere else in the house that have "hot water" marked on them?

There's a box in the utility room with two switches on one says its the water heater control but it doesn't seem to do anything

Could you grab a photo of those?

Sometimes if your immersion heater is up stairs they place a spur to control the outlet down stairs, It's just a thought is all.

He might of shorted out the feed at the immersion heater and popped a fuse else where which is why it's now dead.

Tbh it would be fairly easy to sort for the electrician, just mention you need a feed for new boiler.

thanks for your advice, I'll get some pictures tonight. I think its best as you say I mention this to the sparky before he comes so he can advise if its something he can do at the time, cost etc.

Well the sparky sorted it out, there was another switch that controlled the old immersion controls in the airing cupboard that has been cut off and the socket filled in :rolleyes:

. He popped a few floorboards, found the cable and removed the old socket and bypassed from the circuit. Really pleased with his work and attitude to it actually, he went well above and beyond for me without charging extra.

I paid 450 for the fuse box replacement. He sorted out a few sockets / ran the earth to the mains pipe and did his tests / reports for the house as part of it.

Similar to what I paid last November for the same work, was just sense checking the prices (as I can see you are in the South as well).

Fair enough. To be honest it was technically 400 for the box and 50 to run the earth (about two metres) but if I tell myself I've paid someone £50 to run two metres of cable I'll lose my mind!
