Hey Ian,
Great to hear you are thinking of starting your Gyro journey.
My recommendation would be to concentrate on getting licensed in a standard two seater machine then revisit the single seat options after.
You’ll need to qualify in a tandem / side by side machine and then do your single seat rating.
The issue will be one of CAA restriction on non approved machines being flown in the UK - if you are still keen on single seat once you’ve qualified then either a second hand Benson or the likes would be a more viable option over a new imported machine, although saying that Francis Moyle of Phoenix Aero is in the process of putting through a single seater machine to be available in the UK - https://phoenixaero.co.uk/
Hope this helps,
All the best,
Dave
