Advice on double cooker socket

[Moel]

Anyone with electrical knowledge who can help ahead of being able to get an electrician?

A very old cooker is tripping the electric when it is turned on at the socket. Cooker is hard wired in. Socket has an/off switch for the cooker and a second socket for a plug
which a kettle is in. There is some movement at the wall on the socket though not lots.

ive had cookers trip the electric when an element has gone. The trip would happen when the oven or hob itself was turned on but not when it was just switched on at the wall. The fact this one is tripping when it’s switched on at the wall, before the hob or oven is turned on at the appliance, makes me wonder if the problem is at the socket? The other plug on the socket is working. Does the hardwired side function independent of the plug side?

just trying to work this out as it’s an elderly person. Happy to replace the cooker and pay the company to hardwire it but I guess if they arrive and find problems at the socket they won’t work on it?

any help appreciated.

I don’t think you can assume that it’s the socket necessarily. If there’s a short or any electrical leakage in the cooker, that could trip the circuit. I think that’s marginally more likely than a fault at the socket. But to answer your question about whether the sides are independent, they’re probably using the same feed but a fault on one side wouldn’t necessarily create a problem on the other side.
I think your options are change the cooker and hope it’s not the socket, or get an electrician to check it out first.

If the socket is loose then it really should be looked at anyway.

My guess is yes, if the cooker installers think the socket is not safe or its integrity is compromised then they will not install it.

If you were really lucky then maybe the installer would fix it for you, but they tend to be really clear about which bits they will work on and which bits they won't. Otherwise they would get pulled into fixing all sorts of horror stories and generally their job is to get in, install it and then get out asap.

I would DIY it but if you are not competent then probably best to get an electrician in to look at it. If the socket has been used for many years with a kettle then it is probably wise to replace it anyway.

Trades don't tend to like doing small jobs so maybe a good idea to get them to look at other stuff or do a house safety test at the same time. I think a safety test is relatively cheap.

Get an electrician in to look at it.

I'd have it checked out first. What I would actually do (but I'm very confident with electricity) is remove the hard wired appliances and then see if the fault still occurs. If it does, it's definitely not the appliance!
