I can only find data (albeit after a very quick search up until 2016
The proportion of foreign national HGV drivers between 2006 - 2016 increased from 3% in 2006 to 12%
it would be a reasonable assumption to make, that this increase continued 2016-2019 ?
Average salary in 2016 was £11.06
I did find data to suggest that this had increased to approx. £11.60 per hour YE 2020
The hourly salary is atrocious consdering their responsibilities
