ATE Insurance for Construction Disputes UK Guide
We're not a law firm — we help you find the right legal support. For advice on your situation, speak to a legal adviser or find a solicitor.
Construction projects in the UK rarely run in a perfectly straight line. Delays, defects, variations, payment disagreements and scope creep all create the conditions for disputes, and once a dispute moves towards formal proceedings, the legal costs can climb quickly.
After the Event (ATE) insurance is one tool that parties in construction disputes can use to manage that financial risk. It is a specialist product, usually arranged once a problem has already arisen, and it can change how a party approaches litigation, adjudication or arbitration.
This guide is written for contractors, employers, developers, subcontractors and consultants who want a plain-English overview of how ATE cover fits into a construction dispute, what it typically pays for, and the practical points to think about before taking out a policy.
Overview
ATE insurance is a category of legal expenses cover taken out after a dispute has already started or is about to start. It sits alongside any Before the Event (BTE) cover a business might already hold through its commercial policies.
The defining feature is timing: the policyholder knows there is a real or likely claim, and the insurer prices the premium based on the merits and value of that specific dispute. In a construction context, ATE is most commonly used to cover the risk of paying the other side's legal costs if the insured party loses, along with certain own-side disbursements such as expert witness fees, court fees and counsel's fees.
Policies vary widely. Some are fully deferred and self-insured, meaning the premium is only payable if the case succeeds. Others require an upfront element. Coverage can be tailored to litigation in the Technology and Construction Court, adjudication enforcement, arbitration or mediation-related proceedings, depending on the insurer's appetite.
Key steps
- Assess the dispute early. Before approaching an insurer, gather the core facts, contract documents, correspondence and any expert input you already have. Insurers will want a realistic view of merits, quantum and the likely opponent. A well-organised case summary will usually produce faster quotes and better terms than a vague overview of the problem.
- Speak to a broker or specialist insurer. ATE is a niche market and cover for construction disputes tends to sit with a small number of underwriters. A broker who knows the construction space can approach the right insurers, explain technical points such as adjudication risk, and help you compare premium structures rather than just headline numbers.
- Review the proposed terms carefully. Look at what triggers cover, what is excluded, how the premium is calculated, when it becomes payable and what happens if the case settles. Pay particular attention to the insurer's rights to review the case, any conditions on instructing experts, and how the policy interacts with any funding arrangement.
- Coordinate with your legal team and any funder. ATE often sits alongside a conditional fee agreement, damages-based agreement or third party funding. The pieces need to work together. Your solicitor should confirm the policy aligns with the retainer, and any funder will usually want sight of the ATE terms before committing capital.
- Keep the insurer informed as the case develops. Most policies require the insured to notify the insurer of material developments, settlement offers and changes in prospects. Failing to do so can put cover at risk. Build a simple reporting rhythm with your solicitor so the insurer is never surprised by a major event in the case.

Common questions
Q Who typically uses ATE insurance in construction disputes?
ATE is used across the construction sector. Employers, main contractors, subcontractors, consultants and developers all take out cover at different times. It is particularly common where the claimant has a strong case but limited appetite to absorb the risk of paying the other side's costs, or where a business wants to protect its balance sheet while pursuing a meaningful claim.
Q Does ATE insurance cover adjudication?
Some ATE policies will respond to adjudication and adjudication enforcement proceedings, but not all. Adjudication has its own costs rules, which differ from standard litigation, so insurers tend to treat it as a specialist risk. If adjudication is likely in your dispute, raise it specifically when seeking quotes so the policy wording reflects that exposure.
Q When should I arrange ATE cover?
Earlier is usually better. Once proceedings are well underway and costs have been incurred, insurers may be less willing to offer cover or may charge a higher premium. Approaching the market as soon as a dispute looks likely gives you more options, cleaner terms and a better chance of aligning the policy with any fee arrangement with your solicitor.
Q What does ATE insurance typically not cover?
ATE does not usually cover your own solicitor's base fees, which are often handled through a conditional fee or standard retainer. It will not cover damages or sums payable under a settlement, fines, penalties, or costs incurred before the policy incepts. Deliberate breaches of policy conditions, such as failing to notify the insurer of key events, can also void cover.
Q Is the ATE premium recoverable from the losing party?
For most commercial disputes in England and Wales, ATE premiums are no longer recoverable from the losing opponent. There are limited exceptions in specific areas, but construction disputes generally fall outside those. You should assume the premium will be a cost borne by the insured, whether paid upfront, deferred, or contingent on success.
Q How is the premium calculated?
Insurers price the premium based on the value of the claim, the strength of the merits, the likely costs exposure, the stage of the dispute and the anticipated route to resolution. Premiums can be a fixed sum, a percentage of the cover limit, or staged so that more is payable as the case progresses. Many construction policies use a deferred, contingent structure.
Q Do I still need ATE if I have a conditional fee agreement?
A conditional fee agreement protects you from paying your own solicitor if the case fails, but it does not protect you from paying the opponent's costs if you lose. ATE is what fills that gap. The two products are often used together, and many solicitors will only take on a CFA-funded construction dispute if ATE cover is in place.
