In 2017 (a year for which I have statistics) France spent 25% more per person on healthcare than the UK.

Besides, in 2019, the difference was 4% on a per capita basis -- according to World Bank figures. [1] [2] Probably reflecting the massive difference in spending increases.
Given the NHS' planned spending increases from now until 2025, it is very likely the UK will overtake France altogether. NHS spending plans to 2025 that are already agreed outpace inflation by 6 billion pounds.
