Bond helicopters had a small scheme running a few years ago. Certainly worth giving them a call. I think they have headquarters at Gloucester airport.
As for Bristow's, the last time they ran courses was about 5-6 years ago. The fortunate few went to the States (sunny California I think) to do the basic training. A few of Bristows training pilots went to start their own operation over there - don't know whether its still running, but that was the general route into Bristows for the fresh faced amongst us.
I'd imagine after several years, they might be thinking about recruiting again.
Certainly would't do any harm giving them a call - If you haven't done so already.
Good luck
