What Should You Do When a Construction Dispute Arises Under a JCT or NEC Contract?
Disputes over unpaid invoices, project delays, or defective building works can disrupt well-planned construction projects across England and Wales. Delaying action often heightens financial risk and makes critical evidence harder to secure—especially under JCT and NEC contracts, which impose strict notice and claims deadlines.
Engaging our experienced construction dispute solicitors from the outset provides immediate protection for your commercial interests. Understanding how JCT and NEC contracts differ, the fast pace of adjudication, and how a specialist solicitor navigates the process is essential to enforcing your rights or defending claims, often within just 28 days.

What Is a Construction Dispute and When Should You Instruct a Construction Dispute Lawyer UK?
Construction disputes commonly arise from late or unpaid invoices, disputed variations, project delays, quality defects, or contract terminations. These disputes affect all types of parties: large developers, SME contractors, subcontractors, professional designers, and residential clients. In England and Wales, most disputes start with informal negotiation, but unresolved issues often progress to adjudication, arbitration, or litigation in the Technology and Construction Court.
Approaching our construction litigation team early typically results in more favourable settlements and reduced project disruption.
Moving from typical triggers to actionable steps, it is essential to recognise the main scenarios in which construction disputes commonly arise.
What Types of Construction Disputes Commonly Arise in England & Wales?
Unpaid Invoices and Contract Payments
Unpaid invoices lie at the heart of most disputes. Main contractors may not receive payment for completed works, subcontractors might challenge underpayment, or employers may withhold sums where notice procedures are unclear or disputed.
Defective Construction Work and Quality Issues
Quality disputes frequently occur when works fail to comply with building regulations, contract specifications, or industry best practice. The challenge usually focuses on responsibility, cost, and rectification obligations.
Project Delays and Extensions of Time
Delays often lead to claims for lost time, additional costs, or liquidated damages. Contractors allege employer-caused delays, while employers enforce penalties for late completion. Extension of time disputes are especially common under JCT and NEC frameworks.
Breach of Contract and Termination
Site abandonment, unjustified suspension of work, or wrongful contract termination may all give rise to high-value breach claims, covering lost profits, remedial costs, and damages for repudiatory breach.
The type of contract signed—whether JCT, NEC, or bespoke—directly shapes your legal remedies and strategy.
What Is the Difference Between JCT and NEC Contracts?
Key Features of JCT Contracts
JCT contracts remain the UK standard for traditional and design-and-build projects. Key attributes include:
- Detailed procedures for risk allocation, valuations, and payment certification
- Prescribed processes for variations and claims with strict timeframes for notices
- Defined Extension of Time (EoT) mechanisms and an exhaustive list of “Relevant Events”
Key Features of NEC Contracts
NEC contracts are geared towards proactive risk management and collaboration. Their features include:
- Ongoing early warning and risk registers requiring notification of issues at first sign
- Project Manager-led decision-making in place of the traditional architect or contract administrator role
- Flexible change control processes, shared incentive options, and open book accounting
How Contract Choice Affects Dispute Resolution
JCT contracts require strict compliance with programmed notices; missing a deadline can mean losing entitlement to payment, extensions, or defending quality claims. NEC contracts prioritise continuous communication and shared risk management, but equally demand prompt participation in dispute mitigation.

The contractual framework will also determine how disputes are resolved, with adjudication now central to timely dispute resolution.
How Does Construction Adjudication Work in the UK?
What Is Adjudication? (Definition, Advantages, and Limitations)
Adjudication, governed by the Housing Grants, Construction and Regeneration Act 1996 (the “Construction Act”), allows parties to refer most construction disputes to an independent adjudicator for a temporarily binding decision—typically delivered within 28 days. Key benefits include:
- Exceptional speed (28-day default decision period)
- Lower cost than court or arbitration
- Ensures ongoing project cash-flow—decisions are immediately enforceable unless later overturned
However, complex multi-party disputes or matters involving substantial factual review may be less suitable for adjudication. Adjudicator decisions may also be challenged if there is a lack of jurisdiction or procedural unfairness.
Typical Adjudication Timeline (Including 28-Day Rule)
- Serve a written notice of adjudication on the other party
- Nominate or agree an adjudicator (through contract or nominating body)
- Deliver a referral notice within 7 days detailing your case
- The adjudicator considers witness statements, contract documents, and evidence—usually in writing, sometimes via short hearings
- A decision is reached, almost always within 28 days of the referral, extendable by up to 14 days with agreement
When and How to Start Adjudication Under JCT or NEC Contracts
Either party may initiate adjudication at any phase of a dispute, regardless of the contract type. JCT contracts specify precise nomination processes, while NEC stresses early warnings. In both, the statutory right to adjudicate is protected by law.
If you want insights on enforcing adjudication awards, you may find our article on [Enforcement of Adjudicator Decisions in Construction Disputes](enforcement-of-adjudicator-decisions-in-construction-disputes) useful.
Some complex disputes may be better suited to arbitration or court-based resolution.
Can I Choose Arbitration or Litigation Instead of Adjudication?
Differences Between Adjudication, Arbitration, and Litigation
- Adjudication: Fast, statutory 28-day process, with decisions binding unless overturned by later proceedings. Designed for payment and variation issues.
- Arbitration: Private, contract-based or statutory process (Arbitration Act 1996), suitable for complex or technical disputes. Decisions are final and enforceable, with limited appeal rights.
- Litigation: Public court action, usually in the Technology and Construction Court, best suited for determinations involving fraud, contract validity, or challenging/enforcing decisions.
When Is Arbitration Best?
Arbitration is most appropriate where:
- Confidentiality is paramount
- Technical expertise of an arbitrator is required (such as in engineering disputes)
- The contract specifies arbitration, especially in international or cross-border projects
When Does Litigation Make Sense?
Litigation is essential where:
- The losing party ignores an adjudicator’s award
- There are allegations of fraud or contract validity issues
- Urgent remedies, such as injunctions, are needed (e.g. to stop work or enforce site access)
Clear understanding of each process allows you to respond strategically from the outset.
What Steps Should You Take When Facing a Construction Dispute?
Immediate Actions to Protect Your Position
- Review your contract’s dispute resolution, notice, and claims procedures
- Gather all project records including contracts, correspondence, and payment documents
- Serve formal written notice of your dispute or claim to protect your position
- Avoid making written admissions or offers without expert legal review
- Seek advice before responding to warning letters or considering suspension/termination
Preserving Evidence and Notifying Promptly
Maintain original records, including photographs of defects, site diaries, notes from meetings, and all financial documentation. Back up electronic files, creating an evidence timeline of all critical events—these resources often prove decisive.
How to Instruct a Construction Litigation Solicitor or Adjudication Lawyer
Early legal involvement helps preserve entitlement, improve negotiation outcomes, and prevent costly tactical mistakes. Choose specialists who understand adjudication strategy and contract detail.
Preparation and prompt legal advice are often the keys to recovering sums due or defeating claims.
What Legal Remedies and Defences Are Available for Construction Disputes?
Enforcing or Challenging Adjudicator’s Decisions
Technology and Construction Court enforcement through summary judgment under CPR Part 24 is usually used to rapidly enforce adjudicator decisions. Courts strongly uphold adjudication for cash-flow purposes, only permitting challenge for jurisdiction or breach of natural justice.
Claiming Damages, Rectification, and Interest
Typical remedies for successful claimants include:
- Recovery of unpaid contract sums
- Damages to rectify defects or complete unfinished works
- Specific performance (rare; granted for unique or irreplaceable works)
- Statutory or contract interest on outstanding payments
Defences to Breach or Defective Works Claims
Potential defences can include compliance with contract standards, the trivial nature of alleged defects, procedural missteps by the other party (such as invalid notices), or reliance on valid exclusion or limitation clauses.
With awareness of available remedies and defences, the importance of statutory deadlines becomes clear.
What Laws and Deadlines Apply to Construction Disputes in England & Wales?
Housing Grants, Construction and Regeneration Act 1996
This legislation underpins most construction dispute procedures, guaranteeing the statutory right to adjudicate, requiring payment transparency, and enforcing prompt cash-flow in commercial projects.
Arbitration Act 1996
Where contracts specify arbitration, this Act governs appointment, procedure, and challenge rights. Section 68 provides remedies for serious irregularity; Section 69 allows appeals on points of law, if contractually permitted.
Limitation Act 1980: Contractual Time Limits
- For simple contracts, claims must be brought within 6 years of the alleged breach or the date the cause of action arose.
- For deeds, including many collateral warranties, claims must be issued within 12 years.
- Failing to comply with these limits usually results in the loss of your right to claim, regardless of the merits.
Adjudication Timetables and Critical Deadlines
- Notice of adjudication must be followed by a referral notice within 7 days
- Adjudicator’s decision is due within 28 days of referral, extendable by up to 14 further days with agreement
- Enforcement actions are governed by the Civil Procedure Rules with strict time limits
What Do the Courts Say About JCT, NEC, and Adjudication Disputes?
| Case | Facts | Outcome | Why It Matters |
|---|---|---|---|
| Carillion Construction Ltd v Devonport Royal Dockyard Ltd [2005] EWCA Civ 1358 | NEC contract dispute over jurisdiction | Adjudicator’s decision upheld | Courts will enforce adjudicator’s decision unless clear error or injustice |
| Aspect Contracts v Higgins Construction Ltd [2015] UKSC 38 | Post-adjudication repayment sought | Claim allowed | Adjudicated sums can be reclaimed in further litigation |
| Hutton Construction Ltd v Wilson Properties (London) Ltd [2017] EWHC 517 (TCC) | Employer withheld payment of award | Enforcement granted | Courts apply “pay now, argue later”—prompt payment required |
| Grove Developments Ltd v S&T (UK) Ltd [2018] EWCA Civ 2448 | Pay less notice under JCT | Employer entitled to withhold payment | Strict compliance with notice provisions necessary |
Real court outcomes reinforce the need for strict procedural compliance, rapid action, and awareness that even enforced payments may later be revisited in further proceedings.

Frequently Asked Questions
How do I start adjudication under a JCT or NEC contract?
Serve a written notice to your counterparty, confirm or appoint an adjudicator, then deliver your referral notice within 7 days as stipulated by your contract and the Construction Act.
Can I recover legal costs in construction adjudication?
Generally, each party pays their own legal costs unless the contract or adjudicator’s decision specifically provides otherwise.
What happens if the losing party ignores an adjudicator’s decision?
You can apply to the Technology and Construction Court for summary enforcement, often resulting in an order for immediate payment.
Should I negotiate a settlement before going to court?
Most construction cases settle before final hearing. Early, robust legal advice improves your negotiation leverage and frequently leads to quicker, less costly results.
Can construction disputes be resolved without formal proceedings?
Very often, yes. Negotiation and mediation frequently secure settlements. Adjudication or court action are available if informal talks stall.
What if building work is defective or incomplete?
Attempt prompt rectification or compensation discussions first. If that fails, trigger formal adjudication, arbitration, or litigation for binding remedies.
How long do I have to pursue a construction claim?
Typically, you have 6 years from contract breach (or defect discovery) for simple contracts, or 12 years for deeds.
Should I use a specialist construction litigation solicitor for adjudication?
Yes. Strict rules and complex arguments mean specialist advice is often critical to protecting your position and maximising your prospects.
What evidence should I retain for potential disputes?
Keep all correspondence, signed contracts, payment records, photographic evidence, and formal notices relating to the project.
Who pays for the adjudicator and legal fees?
Adjudicator fees are split as directed by the adjudicator—usually reflected in the award. Legal fees are borne by each party unless the contract or decision expressly provides otherwise.
