Sadly it's not too good to be true because of restrictions on it.
Being limited to non-EASA and UK only. Those 2 things would each make it useless to me personally unfortunately.
for the past 4 years i've enjoyed a 5 year LAPL medical that was conducted at Gatwick by the CAA for a bargain 99 pounds. Since then, they don't offer that service any more. Also, on my next renewal i'll only get 2 years because i'm getting old (Nearly 40!)
