Claiming an ACAS Uplift

When you can ask the employment tribunal to increase your compensation by up to 25%.

Last updated 14 July 2026

Overview

If an employer unreasonably fails to follow the ACAS Code of Practice on disciplinary or grievance procedures, the Employment Tribunal can increase certain compensation awards by up to 25%.

This is known as an ACAS uplift. The same rule can also reduce compensation by up to 25% if the employee unreasonably failed to follow the Code.

When you can claim the uplift

  • You submitted a formal grievance and your employer ignored it or failed to hold a grievance hearing.
  • You were dismissed for performance or conduct, but the employer did not follow a fair disciplinary procedure, for example no warnings, no investigation, or no proper hearing.
  • The employer denied you the right to be accompanied to a disciplinary or grievance hearing.
  • The employer's failure to follow the Code of Practice was unreasonable.

When the uplift does NOT apply

  • Redundancy dismissals, because the ACAS disciplinary and grievance Code does not apply to redundancies.
  • Non-renewal of a fixed-term contract where there is no disciplinary or grievance issue.
  • Ill-health dismissals where there is no disciplinary element.
  • If the employer's failure to follow the Code was genuinely reasonable under the circumstances.

Common questions

Does the uplift apply to my whole award?

Not usually. It generally applies to the compensatory parts of an award rather than every statutory payment, and the tribunal still has discretion about what it adjusts.

How much will I get?

The tribunal can award anywhere from 0% to 25%. The maximum 25% is usually reserved for employers who completely ignore the Code, rather than make minor procedural mistakes.

Can my compensation be reduced instead?

Yes. If you unreasonably failed to follow the ACAS Code, for example by refusing to attend a grievance hearing without good reason or by not appealing your dismissal, the tribunal can reduce your compensation by up to 25%.
