>>it's clear that London's air quality has steadily improved over time:
That's not what the data you linked show, though.
You charted Sulphur Dioxide only, but when you look at say PM2.5, there's not even data for the whole period (09/1993-09/2019):
>>Warning: Valid PM2.5 Particulate measurements are available for only 37% of the requested period.
This means they've got data on <10 years, out of the 26 years in the period.
At least for some pollutants that are widely studied and linked to mortality and negative health outcomes - such as PM2.5, PM10, NO2, there does not seem to be an "improvement", based on these data:
