What is a Polkey reduction?

In an unfair dismissal case, a tribunal can decide that the employer used an unfair procedure but that the employee would still have been dismissed, or might still have been dismissed, if a fair procedure had been followed.

That is commonly called a Polkey reduction. It does not mean the dismissal was fair. It means the compensation is reduced to reflect the chance that the employment would have ended anyway.

This matters because a claimant can win unfair dismissal and still see the compensatory award cut sharply. Where a clear percentage was detected, the average reduction was 63.8%.

What Tribunal Intel found

The audit scanned 2,424 successful or partially successful first-instance unfair dismissal decisions. It excluded EAT cases and procedural-only rulings, then focused on published cases where the employee had at least some success.

Polkey was engaged in 443 cases (18.3%). A reduction was detected as applied in 151 cases (6.2%). In another 113 cases, the tribunal appeared to reject or decline a Polkey reduction.

What this means for a loss schedule

If you are preparing a statement of loss, set out the losses you say were caused by the dismissal first. If Polkey is relevant, model it separately as a settlement or risk scenario, so it is clear what you are claiming and what the award might look like if the tribunal applies a discount.

For claimants, the statement of loss should normally start from the full claim. Polkey is better treated as a settlement or risk scenario unless you are deliberately making a concession. For employers, the key question is evidence: what fair process should have happened, and what would probably have happened after it?
