What is the NHS High Cost Area Supplement (HCAS)?
What is the NHS High Cost Area Supplement (HCAS)?
The NHS High Cost Area Supplement (HCAS) or “London Weighting” is an additional payment for NHS staff on Agenda for Change contracts who work in London and the surrounding areas. The payment is a percentage of salary, subject to minimum and maximum values.
Can you get High Cost Area Supplements (HCAS) outside of London?
HCAS only applies to jobs in London and the immediately surrounding areas. However, a small number of jobs outside London (particularly in areas with high cost of living or remote areas) do receive additional Recruitment and Retention Premia (RRPs).
How much extra money will I get from the High Cost Area Supplement?
The value of the High Cost Area Supplement depends on your location.
