Do you know if it is a ring main with 2
lots of 2.5mm2 or a single 2.5mm2 or a single 4.0mm2 cable?


As mentioned it's a 2.5mm2 radial.

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.


It runs loose up inside an partition wall for ~1.5m, through joist centres for ~8m and then down behind dot-and-dab skimmed plasterboard on a block wall for ~1.5m. No insulation anywhere along the run.
