What employers mean by salary exchange

Pension salary exchange is a salary sacrifice arrangement where contractual salary is reduced and the employer contributes more into pension instead.

Why employers like it

It can reduce employer National Insurance, simplify pension contributions, and create a clearer saving mechanism.

What employees should ask

Check whether the employer shares any NI saving, whether life assurance uses notional salary, and whether the arrangement affects any salary-linked benefits.
