There is obviously a fault on that socket circuit.
A picture of the rest of the consumer unit would be helpful.
Is there an extractor unit above the hob ?
There is an extractor hood, yes - and I didn't buy it or fit it - but I asked them about it and it is not even remotely new. I know that when their tenancy started 3 years ago - this was actually an over-hob light fitting. I may have a closer look at this, I don't think I saw a socket for it.
I will grab another picture of the whole consumer unit too, and come back.
