You make reference to Bristol gs and the uk so illl assume you want to get a JAA licence issued by the caa in the uk. You are obviously quite experienced and have jet ratings on your ATP.
1. If your in the uk go to the flight crew licencing walk in reception at the caa in Gatwick with your paperwork and logbooks and tell them what you want/ask what to do next - they are very helpful.
2. If your not in the uk, call the flight crew licencing section at gatwick, make contact and explain your situation - deal with them directly, they are helpful and will be able to advise you accordingly.
