I started work in 1954 with Surrey County Council. As I was under 18 I couldn’t join the pensio scheme, but did so on my birthday in 1955, I think the 2/3 final salary pension was still in vogue but only for folk who had joined a good bit earlier. In 1955 for new entrants it was 1/2 final salary; in fact, I have a vague memory that it was 1/2 average salary of your last three years, but by the time I retired, by now transferred to the NHS it was 1/2 of one’s final year
