If your business is heading into a commercial dispute, one of the first questions that tends to keep directors awake at night is simple: what is this going to cost me? The honest answer is that commercial litigation costs in England and Wales are rarely straightforward. They sit on a sliding scale shaped by the complexity of the case, the behaviour of both sides, and the cost orders the court ultimately makes. Even when you win, you often do not recover every penny you have spent. This page walks through how litigation costs are structured, the main rules the courts apply when deciding who pays what, and the practical steps you can take to keep your exposure under control. Think of it as a plain-English map of the financial terrain before you commit to proceedings.

Overview

Commercial litigation costs are the sum of everything you spend pursuing or defending a business dispute through the courts. That includes court issue fees and hearing fees, the charges of the solicitors or legal representatives handling your file, barristers' fees if counsel is instructed, and payments to any expert witnesses needed to support the technical aspects of your case.

On top of that you may face disbursements such as mediation fees, process server charges, travel, and the cost of preparing trial bundles. In higher-value or more complex matters the figures can escalate quickly, which is why the Civil Procedure Rules give the courts wide powers to manage and limit spending through costs budgets, case management orders, and ultimately costs orders at the end of the case.

Understanding how these mechanics work before you issue a claim, or before you dig in to defend one, is often the difference between a commercially sensible strategy and an expensive mistake.

Key steps

  1. Map your likely cost exposure early. Before you issue a claim or file a defence, get a realistic picture of what the dispute could cost across its full lifecycle. Factor in pre-action correspondence, disclosure, witness evidence, expert reports, counsel's fees for hearings, and trial preparation. Your own costs are only half the picture, you also need to think about what you might have to pay the other side if you lose.
  2. Consider settlement and Part 36 offers. The Civil Procedure Rules reward parties who make sensible offers to settle. A well-pitched Part 36 offer can shift the costs burden dramatically, particularly if the other side fails to beat it at trial. Even without Part 36, open negotiation, mediation, or other forms of alternative dispute resolution often resolve matters at a fraction of the cost of a full trial.
  3. Comply with the pre-action protocols. The courts expect parties to exchange information, narrow issues, and try to resolve matters before proceedings are issued. Failing to follow the relevant protocol can result in cost penalties later, even for a winning party. Keep records of every letter, email, and offer so you can demonstrate reasonable conduct if costs are argued.
  4. Monitor your costs budget throughout. In multi-track cases, parties typically file and exchange costs budgets on Form Precedent H, and the court will set a budget that caps what can be recovered. Once that budget is approved, going significantly over it without a good reason and a variation order can mean absorbing the overspend yourself, even if you win the case.
  5. Prepare a detailed bill of costs after judgment. If you succeed and are awarded your costs, you will need to prepare a bill in the prescribed format and serve it on the paying party. The other side can raise points of dispute, and if the bill cannot be agreed it goes to detailed assessment. Good contemporaneous records, accurate time recording, and proper file management are what make the recovery exercise actually work.

Common questions

Q Does the losing party always pay the winner's costs?
The general rule in England and Wales is that costs follow the event, meaning the unsuccessful party pays the successful party's costs. But this is a starting point, not a guarantee. The court has wide discretion and can reduce or reverse a costs order based on conduct, the issues each side won or lost on, exaggerated claims, unreasonable refusal to mediate, or the impact of any Part 36 offers made during the proceedings.
Q What is the difference between the standard basis and the indemnity basis?
On the standard basis, the court only allows costs that are proportionate and reasonably incurred, and any doubt is resolved in favour of the paying party. Recovery is often well short of what the winner actually spent. On the indemnity basis, proportionality does not apply and doubt is resolved in favour of the receiving party, so recovery tends to be higher. Indemnity costs are typically reserved for cases involving poor conduct.
Q What is a Part 36 offer and why does it matter for costs?
A Part 36 offer is a formal settlement offer made under a specific part of the Civil Procedure Rules. It carries significant cost consequences if rejected and then not beaten at trial. For a claimant whose Part 36 offer is matched or exceeded at judgment, the court can award enhanced interest, indemnity costs, and an additional uplift. It is one of the most powerful costs tools in commercial litigation.
Q Can I recover all my legal costs if I win?
Rarely. Even successful parties typically recover a proportion of what they have actually paid their lawyers, often somewhere in the region of 60 to 75 percent on the standard basis, though the exact figure varies widely. Costs budgeting, proportionality tests, and detailed assessment all tend to reduce the recoverable sum. You should plan on the basis that a meaningful chunk of your legal spend will not be recovered, even in victory.
Q What is a costs budget and do I have to file one?
In most multi-track cases with a value below a set threshold, parties must file and exchange costs budgets on Precedent H setting out anticipated costs for each phase of the litigation. The court then makes a costs management order approving or revising those figures. Recovery at the end of the case is generally capped at the approved budget, so taking budgeting seriously early on is crucial.
Q What happens if I cannot afford to pay the other side's costs if I lose?
Adverse costs risk is one of the biggest factors in deciding whether to litigate. Options include after-the-event insurance, conditional fee arrangements, damages-based agreements, and third-party litigation funding. Each has advantages and drawbacks. It is also worth considering whether security for costs might be sought against your opponent, particularly if they are an overseas company or in uncertain financial health.
Q How long does detailed assessment of costs take?
Detailed assessment can take several months, sometimes longer, depending on court availability and whether the parties reach agreement along the way. Many bills settle through negotiation once points of dispute and replies have been exchanged. If a full assessment hearing is needed, the process is more involved. Interim payments on account of costs are often ordered at the end of trial to ease cashflow while assessment is pending.
