The CAA launched the PROUD scheme to encourage pilots to build their skills. There are several schemes around, all of which have criteria such as total hours experience, cross-country miles and land-aways, new experiences and attendance at seminars.
If you fly at Andrewsfield, I recommend joining their Flight Levels scheme. The Bronze level is aimed at newly minted PPL’s and can be achieved in a modest amount of flying over 1-2 years. The Andrewsfield scheme is unique in offering members a discount on flying costs. Bronze gets you a 5% discount; the Silver, Gold and Diamond levels are more challenging, with commensurately higher rewards.
If you don’t fly at Andrewsfield, you may wish to consider the AOPA or LAA schemes.
