Don't undersell youself or your experience.
A large proportion (majority?) of UK maintenance engineers are ex military.
Most of the apprenticeships died years ago and are only just being resurrected.
The money in the airlines and the offshore helicopters has been rising consistantly.
With a overtime £50,000+ is achievable.
My basic has just risen to £39,000 in my first year with a new employer.
If the restrictions are lifted off my licence I get a further £4,000
Any additional type ratings bring £1500 each.
If I get B2 (fat chance) then another £4,000 is added.
