The King's Fund produced a research paper in 2018 on life expectancy and good health. The whole thing can be read here:

In case you don't don't want to click on the link or plough through the whole lot, here are some highlights:
By 2016 life expectancy at birth had increased to 79.5 years for males and 83.1 years for females.
Healthy life expectancy has also increased, but not at the same rate as life expectancy, so more years are spent in poor health. Although an English male could expect to live 79.5 years in 2014–16, his average healthy life expectancy was only 63.3 years – ie, he would have spent 16.2 of those years (20 per cent) in ‘not good’ health.
An English female could expect to live 83.1 years, of which 19.2 years (23 per cent) would have been spent in ‘not good’ health. And although females live an average of 3.6 years longer than males, much of that time is spent in poor health – they experience only 0.6 more years of good health than men.
People living in more affluent areas live significantly longer than people living in deprived areas. In 2014–16, males living in the least deprived 10 per cent of areas in England and Wales could expect to live almost a decade (9.3 years) longer than males living in the 10 per cent most deprived areas, and for females the gap was 7.4 years. The gap in healthy life expectancy at birth is even greater – about 19 years for both males and females, and those living in the most deprived areas spend nearly a third of their lives in poor health, compared with only about a sixth for those in the least deprived areas.
