What Are Contract Compensation Events in UK Construction and How Do You Claim Under the NEC?
Missing the deadline to notify a compensation event is a costly mistake that can leave your business unable to recover time or money for project changes or delays. Under the NEC contract, strict procedural rules apply, and failing to act on time can disrupt your cash flow and jeopardise delivery dates.
Compensation events in UK construction commonly arise in NEC contracts when listed events, such as employer changes or site conditions, impact time or cost after the start of works. It is vital to understand the NEC compensation event examples and the contract rules for claiming time or money.
You will discover how to spot construction delay events, comply with time extension contract requirements, and preserve your entitlement. If you need urgent support, our London-based construction solicitors offer clear, practical advice for projects in England & Wales.
What Is a Contract Compensation Event in UK Construction Projects?
A compensation event is an event defined in the contract that entitles a party—usually a contractor or subcontractor—to extra payment and/or time due to changes or risks not priced in at contract signing. Under NEC terms, common examples include additional instructions by the employer, unexpected physical conditions, or variations in design.
The purpose is to maintain commercial fairness if risk shifts after the works begin. These events are not dependent on fault and can arise at any point during the project.
If you are unsure whether your circumstances qualify, our contract review service can help assess your position quickly.
Why and When Do Compensation Events Arise Under NEC Contracts?
Compensation events most often occur under NEC contracts when something outside the original contract terms affects the works. This may result from the employer’s instruction, delays in information, or abnormal site conditions.
The NEC contract encourages early, written notice to keep both parties informed and allow costs and timelines to be properly managed. Notification deadlines are critical: miss them, and entitlement is typically lost.
What Types of Compensation Events Can You Claim For Under the NEC?
The NEC contract (including NEC3 Clause 60.1 and NEC4 Clause 60.1) outlines compensation events, but specific details may differ for your project. Typical NEC compensation events include:
- Employer-instructed changes to scope or design
- Delays due to late site access or site conditions not foreseen at tender
- Variations, suspensions, or additional work instructions
- Failure of the employer to provide information or materials on time
- Errors or delays by consultants or suppliers engaged by the employer
Always review your contract “Z clauses” and amendments as these often alter or add to the list of compensation events.
If you are in doubt, one of our expert lawyers can review your contract and advise whether your issue falls within a valid event.
How Do Compensation Events Affect Project Cost, Deadlines and Risk?
If a compensation event is accepted, you can obtain both a change to the contract price and an extension to the project completion date. This provides:
- Reimbursement for genuine extra costs actually incurred
- Protection from liquidated damages due to delay attributable to the event
- Confidence that the risks you did not agree to carry are not unfairly pushed onto you
Failure to notify or provide evidence can mean the employer successfully resists your claim, bringing cash flow issues and potential disputes.

How to Notify and Claim a Compensation Event: Step-by-Step Guide
Protecting your rights under NEC contracts means promptly following the notification procedure. Here is a structured guide:
- Identify the event: Check your contract’s compensation event list.
- Notify in writing: Submit formal notice to the project manager within the contract’s notice period—usually 8 weeks of becoming aware.
- Describe the consequences: Clearly set out the cost and programme impacts.
- Evidence support: Provide contemporaneous emails, site diaries, instructions, photos, and financial breakdowns.
- Maintain the process: Respond to requests for further information and monitor deadlines.
- Wait for assessment: The project manager typically has 1–3 weeks to evaluate and decide if the claim is valid.
Our experienced construction lawyers can advise on the correct wording, deadlines, and documentation for your compensation events.
What Evidence Do You Need for a Successful Compensation Event Claim?
To succeed with a compensation event claim, your evidence must be thorough and contemporaneous. Decision-makers view evidence such as:
- Dated site diaries and logs
- Photographs and videos capturing arise of the condition or event
- Copies of relevant instructions, variation orders, and project manager responses
- Breakdown of increased labour, materials, and plant costs
- Complete correspondence chains and meeting minutes
If you are preparing a large claim and want it checked for completeness, our evidence assessment service will identify any gaps before you notify.
What Deadlines and Rules Apply to NEC Compensation Events?
The NEC contract imposes strict time limits. In most cases, you must:
- Notify within 8 weeks of becoming aware of a compensation event (NEC3/NEC4 Clause 61.3, unless amended)
- Submit a fully documented claim for assessment
- Reply to requests for information promptly
If you miss the notification deadline, the NEC contract generally ends your right to claim, even if your costs are genuine and the employer is not prejudiced. Project managers typically have 1–3 weeks to issue their assessment or seek further clarification.
If you need an urgent claims audit to check for missed deadlines, our team can provide rapid advice.
What Laws and Deadlines Apply to Contract Compensation Events UK?
While the NEC contract spells out process, statutory law in England & Wales also provides key protections and obligations:
| Law or Rule | Summary | Application | Why It Matters |
|---|---|---|---|
| Construction Act 1996 | Statutory framework for payments & disputes | Protects right to prompt payment and adjudication | Compensation event claims are treated as “construction operations”—they can be adjudicated swiftly |
| NEC3/NEC4 Clauses 60–61 | Contractual rules for claim notification, evidence, and deadlines | Sets eight-week notice, what information is required, and how disputes are resolved | Missing the process set by the contract almost always invalidates your right to costs or time |
Missing any contract time bar is a common pitfall for both main contractors and subcontractors.

What Do the Courts Say About NEC Compensation Event Claims?
Courts and adjudicators in England & Wales treat NEC contract rules seriously and generally uphold strict compliance. Recent cases illustrate this approach:
| Case | Facts | Outcome | Why It Matters |
|---|---|---|---|
| John Doyle Construction Ltd v Laing Management (Scotland) Ltd [2004] | £2.5m NEC claim for time and cost, poor notice and lack of evidence | Most claims rejected; lack of proper notice and contemporaneous records | Courts expect prompt notice and solid evidence for each event |
| Thomas-Firm JV v UK Highways M25 (2017) | Scope changes caused delays, but contractor notified outside contract period | All late claims denied | NEC time bars are enforced even where underlying claims are otherwise meritorious |
| Costain Ltd v Bechtel Ltd [2005] | Detailed site change with full evidence and records, but partial notification | Partial claim allowed, only for events properly notified and recorded | Documentation and formal contract compliance are key to securing recovery |
The message is clear: courts expect strict procedural compliance and timely, well-evidenced claims.

What Happens If Your Compensation Event Claim Is Rejected or Not Paid?
A rejected compensation event claim does not mean you have reached the end of your options. NEC contracts and UK law generally provide for dispute resolution, including adjudication and litigation.
If your valid claim is unpaid, your options include:
- Referring the dispute to adjudication, mediation, or court
- Presenting further or corrected evidence
- Negotiating a direct, commercial settlement
- Continuing works under protest to maintain rights
Prompt action and fully evidenced submissions can make it easier to achieve positive outcomes. If your claim has stalled or been rejected, our lawyers can assess your options and draft your response strategy.
Can You Challenge or Resolve Compensation Event Disputes Without Court?

We are experienced in representing clients in all major dispute forums, including mediation and adjudication, and can help you protect your commercial interests without unnecessary court action.
Common Pitfalls and Mistakes in Compensation Event Claims (and How to Avoid Them)
Many claims fail because of procedure and evidence, not the merits. Key mistakes include:
- Missing notice deadlines under the NEC contract
- Relying entirely on verbal discussions or informal notice
- Not linking the event directly to specific contract clauses
- Poorly maintained records or lack of robust evidence
- Failing to detail the specific effect on cost, time, or programme
Book a contract “health-check” with our claims team if you want to ensure your evidence and procedures are watertight.
Practical Examples of Compensation Events Under the NEC Contract
Real-world NEC compensation events show how claims arise and proceed:
- The employer alters the design, triggering a four-week site extension and £35,000 in extra material costs.
- Flash floods close the access road for two weeks, increasing plant hire charges and requiring additional site security.
- The project manager delays issue of final working drawings, forcing unscheduled overtime to maintain progress.
- Unexpectedly poor soil conditions at a housing development result in additional piling works not priced at tender.
Each event demands a prompt, written claim with precise supporting documentation, submitted per the contract procedure. Delay or weak evidence erodes your negotiating power and reduces the likelihood of a successful outcome.

Frequently Asked Questions
How do I know if something is a compensation event under NEC?
Check your contract’s NEC Clause 60.1 for listed events and any amendments specific to your project. If in doubt, our lawyers will review your contract and confirm your rights.
Can a compensation event cover both additional costs and time extensions?
Yes, most compensation events entitle you to additional payment and an extension for completion, provided the impacts are properly evidenced.
What if the employer disputes that an event qualifies for compensation?
The NEC provides for adjudication and other dispute resolution methods. If the project manager disagrees, you may escalate the dispute promptly for a specialist decision.
Is there any flexibility if I miss the NEC notification deadline?
Very little. Courts and adjudicators typically enforce the NEC time bar strictly, though rare exceptions arise if the employer has not suffered any prejudice and contract terms allow.
Do compensation event procedures apply to JCT contracts as well?
JCT contracts have their own mechanisms for variations and time or cost claims. While similar in principle, they have different processes and notice requirements—review your JCT contract closely.
What documentation helps most in contesting a rejected claim?
A daily site diary, written notifications, clear cost breakdowns, and copies of all employer instructions or contract changes give your claim maximum credibility.
Can a verbal instruction count as a compensation event?
Yes, but you must record the instruction in writing and notify the project manager in compliance with the NEC contract to protect your entitlement.
How are compensation events valued under NEC contracts?
Valuation is based on quotations and a schedule of cost components, reviewed and agreed with the project manager, taking into account actual defined costs, time, and risk factors.
Is mediation a good alternative for NEC compensation event disputes?
Mediation can resolve disputes effectively if both sides want a negotiated outcome and wish to preserve relationships.
What should I do if I’m facing multiple overlapping compensation events?
Maintain distinct records for each event, issue notices for each within time limits, and seek coordinated legal advice to present your claims in the most effective way.
