Assuming you mean Airways at Exeter, I suggest you also consider Flightpass
www.flightpass.co.uk When I trained with them early last year there were two people undertaking conversions there, one from FAA licences and one military guy. The head of training there, who did my CPL, used to instruct in the States so he knows the FAA system very well.
One of the main pluses for me was the very individual attention, which I think would be particularly useful for conversion training, although I have no actual experience of conversions myself. All the best,
