Because you are allowed to assume 13A from a double socket, the
maximum current flowing can be assumed to be below 26A.

No, the general rule is to assume 20 A load on a double socket (per the BS
1363 test requirement). That stacks up with the 'double socket ton a 2.5
mm^2 unfused spur' rule for standard final circuits.

In the current case in question it's unlikely that more than 5 kW would be
required overall and I'd recommend changing the fuse to 20 A.
