An equal pay audit is the most effective way of checking that your organisation is complying with its equal pay obligations.

Why you need to carry out this audit?

Under the Equality Act 2010, women are entitled to equal pay with men doing equal work. This means you need to be confident that your pay system delivers equal pay and protects you against the risk of an equal pay claim.

What is an equal pay audit?

An equal pay audit involves comparing the pay of men and women doing equal work in your organisation. It has three main purposes:

  • to identify any differences in pay between men and women doing equal work
  • to investigate the causes of any (differences in pay between men and women doing equal work, and
  • to eliminate instances of unequal pay that cannot be justified.

An audit is not simply a data collection exercise. It entails a commitment to put right any unfair pay inequalities. This means that the audit must have the involvement and support of managers with the authority to deliver the necessary changes. It is also important to involve workforce representatives to maximise the validity of the audit and the success of any subsequent action taken.
