If it's a single run of 2.5mm2 then you will need to check how it's been clipped.between the consumer unit and the double socket.

Depending on what it's been mounted onto and what surrounds it to determine if it's a 16A or 20A MCB.

You should not have to do that. It should be installed so that it's
