Specifically, I'm interested in amps rating for 2x1.5 sq.mm. and
2x2.5 sq.mm (220V). I tried to google no luck so far.

For flexible cords you need Table 4H3A of BS 7671.

2x or 3x 1.5 mm^2 - 16 amps (single-phase AC)
2x or 3x 2.5 mm^2 - 25 amps (ditto)

Also, in the case of an extension cable, beware of max length
due to earth fault loop impedance. In the case of an extension
cable fused at 13A, that is 15m for 1.5 mm² and 25m for 2.5 mm².
Any longer than these values and you need to ensure the cable
is protected by an RCD, or reduce the value of the fuse
protecting the cable proportionally below 13A.
