Employment Tribunal Cost UK 2026

The big numbers

Step 1: ACAS early conciliation (free, mandatory)
Before lodging a tribunal claim you must notify ACAS and give them an opportunity to broker a settlement. This is free, mandatory, and takes up to 6 weeks. ACAS contacts both you and your employer to test whether a deal can be reached. If conciliation succeeds, you sign a COT3 settlement agreement, are paid, and the matter ends. If it fails, ACAS issues a certificate (with a reference number) allowing you to proceed to tribunal.
Around two-thirds of early conciliation cases do not go on to a tribunal claim. The free ACAS service is the single most cost-effective intervention in any employment dispute.
Step 2: lodge the ET1 claim (free)
If conciliation fails you have 3 months less one day from the act complained of (or, for discrimination, from the last act in a continuing course of conduct) to lodge the ET1 claim form. There is no fee. Lodge online at gov.uk/employment-tribunals.
Step 3: instruct a solicitor (or self-represent)
This is the cost-bearing decision point. The four routes:
- Self-represent. £0 in legal fees. ACAS guidance, Citizens Advice, and the tribunal's own practice directions are designed for litigants in person. Most viable for straightforward unfair dismissal claims with a clear factual narrative.
- Trade union representation. If you are a member, most unions provide legal representation for employment claims free of charge as a member benefit. If you are not a union member, joining mid-dispute generally does not get you free representation -- unions vet new members' claims first.
- Solicitor on a conditional fee (CFA, no-win-no-fee). The solicitor charges you nothing if you lose, and takes a success fee (typically 25 to 100 per cent uplift on their base fee) from your award if you win. Many UK employment specialists offer CFA for clear-cut cases worth £15,000+.
- Solicitor on full private retainer. Hourly rate (£247 to £393/hr Grade B GHR by region) or fixed fee. Total cost £10,000 to £25,000 for a typical unfair dismissal up to and including final hearing; £15,000 to £50,000 for discrimination or whistleblowing. Suitable if you can afford to lose this money since it is rarely recoverable.
Compensation: what tribunals award
If you win, the tribunal can award:
- Basic award (unfair dismissal): calculated by age × years of service × week's pay (capped at £751/week from 6 April 2026). Maximum approximately £22,530.
- Compensatory award (unfair dismissal): capped at the lower of 52 weeks' pay or £123,543 (from 6 April 2026, uprated annually; the cap is due to be removed from 1 January 2027).
- Discrimination claims: uncapped. Injury to feelings awarded on the Vento bands (for claims presented on or after 6 April 2026: lower £1,300 to £12,600, middle £12,600 to £37,700, upper £37,700 to £62,900; updated annually for inflation).
- Whistleblowing claims: uncapped.
The median unfair dismissal award (where the claimant wins) is around £6,700; discrimination medians are higher, around £16,000 to £17,000, and mean awards are higher still because of a long tail of large discrimination awards (MoJ tribunal statistics, 2023/24). Over 40 per cent of cases that reach a full hearing succeed on at least part of the claim.
Costs orders: when the loser pays
In employment tribunals, costs orders are exceptional, not the default. Unlike civil litigation, the tribunal does not award costs to the winner as standard. Costs orders are made only where one side acted unreasonably: pursued a hopeless claim or defence, lied, made baseless allegations, or refused a reasonable settlement offer. Costs awards are typically modest (£1,000 to £20,000), which is the most a tribunal can fix without a detailed assessment of the costs; larger orders go to detailed assessment. The tribunal can also take the paying party's means into account when deciding whether to make an order at all.
Practical consequence: even if you win a clean unfair dismissal claim, you will usually not recover your £15,000 solicitor fee from the employer. Factor this into the cost-benefit decision before instructing privately.
What an employment tribunal costs the employer
The figures above are the claimant's side of the ledger. The cost to the employer of defending a claim is a separate calculation, and it is one many businesses underestimate: because the tribunal runs an each-side-pays costs regime, an employer that wins still absorbs its own legal bill. For the full breakdown from the business's perspective, see what an employment tribunal costs an employer.
| Employer cost | Typical amount |
|---|---|
| Legal defence (unfair dismissal, to final hearing) | £8,000 to £30,000 + VAT |
| Legal defence (discrimination / whistleblowing) | £20,000 to £50,000+ + VAT |
| Barrister (hearing day rate) | £1,500 to £7,500 + VAT/day |
| ACAS early conciliation | Free (mandatory both sides) |
| Settlement (COT3 via ACAS, or protected conversation) | Negotiated (often less than a defence) |
| Management time | Up to ~1 month of internal time |
| Award if the claim succeeds | Unfair dismissal capped at £123,543; discrimination uncapped |
| Cost recovery if the employer wins | Usually £0 (each-side-pays) |
Legal-defence ranges reflect the pricing firms publish under the SRA Transparency Rules for defending tribunal claims. Compensation caps are the statutory limits for dismissals on or after 6 April 2026 (the unfair dismissal cap is due to be removed from 1 January 2027).
The decisive number for an employer is not the potential award but the cost of defending regardless of merit. Because winning recovers no legal fees, defending a weak unfair dismissal claim to a hearing can cost more than settling it. That economics, not the strength of the claim, is why a large share of tribunal claims settle at the ACAS conciliation stage. For an employer the cheapest interventions are early: sound documentation before dismissal, a fair procedure, and engaging seriously with ACAS conciliation before costs build.
