2. Run an extension lead from the house ring main to the garage. The new
compressor runs off a standard 13 amp socket. Is this likely to cause any
problems ?

You need to determine which circuit the garage is actually fed from,
then you could run the 2nd unit from a different circuit.

You will also need a thick extension cord. For a 13A extension cord,
1.25mm² conductors OK up to 12m long,
1.5mm² conductors OK up to 15m
2.5mm² conductors OK up to 25m (but 2.5mm² won't fit in a 13A plug).
