Hi,
We cannot comment on an employer’s specific arrangements, we can only provide general advice and signpost to guidance.
Any deduction from pay, outside of a very specific list of exceptions, is likely to reduce a worker’s minimum wage pay. Salary sacrifice will always reduce a worker's minimum wage pay. The worker is in essence giving up that portion of their pay in exchange for something else, so it cannot be included in any minimum wage calculations. Any determination would depend on the arrangements in place.
As you require advice relating specifically to working arrangements you have in place or are considering introducing, then please seek independent legal advice or contact the Advisory, Conciliation and Arbitration Service (ACAS) on 0300 123 1100.
Alternatively, for more information on deductions from pay, payments by workers, and the impact on National Minimum Wage pay please see the following guidance:

Thank you.
