Have you considered instructing ? You probably already have an instructor rating and a lot of flying experience. I'm working in a SE Asian country that follows Easa rules and I see they allow over 65's to keep flying as instructors only. Their cpl gets downgraded to ppl but the instructor rating remains and they can still fly.
Maybe The instructor job in the U.K. is not well payed but there are helicopter academies around the world that pay good salaries for instructors for example: Horizon in the UAE.
Best of luck!
