Construction projects rarely proceed precisely as planned. Delays, variations, payment disagreements, defective works and contractual interpretation disputes are a common feature of the industry. Where a project is governed by a Joint Contracts Tribunal (JCT) contract, understanding the available dispute resolution mechanisms is essential to protecting your legal and commercial position.
What is a JCT Contract?
The JCT publishes the most widely used suite of standard form construction contracts in England and Wales, covering both private and public sector projects. Principal forms include the Standard Building Contract (SBC), Design and Build Contract (DB), Intermediate Building Contract (IC), Minor Works Building Contract (MW) and Management Building Contract (MC). Whilst each form differs in scope, and the allocation of risk and procedural requirements varies between forms, the core provisions governing payment, variations, extensions of time, loss and expense, defects and dispute resolution remain broadly consistent across the suite.
Common Categories of JCT Dispute
Payment Disputes
Payment disputes are among the most frequently encountered in construction. Typical issues include non-payment or under-payment of interim applications, defective payment notices, failure to serve a valid Pay Less Notice, under-certification, final account disagreements and retention disputes.
The payment regime under JCT contracts operates alongside the statutory framework established by the Housing Grants, Construction and Regeneration Act 1996 (as amended) (the "Construction Act"), which applies to all qualifying construction contracts. Where the paying party fails to issue a valid Pay Less Notice within the prescribed timescales, it may become liable to pay the full sum applied for, regardless of the underlying valuation of the works at that stage, although the true value may subsequently be determined in a later adjudication or other proceedings.
Extension of Time Disputes
JCT contracts entitle a contractor to an extension of the Completion Date where delay is caused by a contractually recognised Relevant Event, including variations, late design information, employer delay or interference, exceptionally adverse weather and other Relevant Events specified in the contract. Disputes arise in relation to whether a Relevant Event has occurred, whether notice requirements have been met, the appropriate length of any extension, and whether liquidated damages are recoverable. Failure to secure a valid extension may expose a contractor to liquidated damages liability for any period of culpable delay.
Loss and Expense Claims
Where regular progress has been materially affected by matters for which the employer bears contractual responsibility, such as late instructions, design changes, delayed site possession or employer interference, the contractor may also be entitled to recover loss and expense. To succeed, the contractor must establish a contractual entitlement, causation, actual financial loss and adequate evidential support. Inadequate contemporaneous record-keeping remains one of the principal reasons why otherwise meritorious claims fail.
Variations
Disputes relating to variations commonly concern whether an instruction constitutes a variation at all, the valuation of additional or substituted work, the treatment of omissions, changes to specification, and the applicable pricing methodology. JCT contracts contain detailed valuation mechanisms which should be followed carefully; departure from those procedures may complicate the recovery of sums properly due.
Defective Works
Defect disputes may arise during construction, after practical completion and during or after the Rectification Period. Common allegations include poor workmanship, non-compliance with specification, defective design (where design responsibility has been assumed by the contractor) and the use of unsuitable materials. The allocation of design responsibility under the relevant contract form is frequently a determinative issue.
Practical Completion
Certification of practical completion carries significant contractual consequences: it triggers release of the first half of the retention, commences the Rectification Period, transfers insurance obligations and brings the employer's entitlement to liquidated damages to an end. Disputes frequently arise where one party contends practical completion has been achieved whilst the other maintains that outstanding or defective works prevent certification. Whether practical completion has occurred is a question of fact and degree, determined by reference to the contractual provisions and the circumstances of the project.
Termination
Termination is the most serious remedy available under a JCT contract and should never be exercised without careful legal advice. Grounds may include insolvency, failure properly to progress the works, specified contractual defaults, non-payment, serious contractual breach and other grounds set out in the relevant JCT form. Strict procedural requirements, including the service of specified notices, must be satisfied before termination can validly take effect. Purported termination on unsupported grounds, or without following the prescribed procedure, may itself constitute a repudiatory breach, exposing the terminating party to a substantial damages claim.
Dispute Resolution
Adjudication
Adjudication is the predominant dispute resolution mechanism in the construction industry. A statutory right to refer disputes to adjudication at any time is conferred by the Construction Act in respect of all qualifying construction contracts, and most JCT forms contain an express adjudication clause.
The process typically concludes within 28 days of referral and produces a provisionally binding decision enforceable through the courts. Adjudication is particularly suited to payment disputes, extension of time and loss and expense claims, and valuation disputes. Challenges to enforcement are available only on narrow grounds i.e. lack of jurisdiction or a material breach of the rules of natural justice.
Mediation
Many disputes are capable of resolution through structured mediation without resort to formal proceedings. Mediation offers confidentiality, preservation of commercial relationships, flexibility and a significant reduction in legal costs. The courts actively encourage parties to consider alternative dispute resolution; an unreasonable refusal to engage may carry costs consequences, even where the refusing party ultimately succeeds at trial.
Arbitration
Where the parties elect for arbitration in the Contract Particulars, arbitration provides a confidential, final determination by an arbitrator, often with specialist construction expertise. Awards are internationally enforceable under the New York Convention 1958. Whilst less common than adjudication in domestic disputes, arbitration remains an important option for complex or high-value projects.
Technology and Construction Court
Where disputes cannot be resolved by other means, proceedings may be issued in the Technology and Construction Court (TCC), a specialist court within the Business and Property Courts of the King's Bench Division, with expertise in construction, engineering and infrastructure matters. The TCC is the appropriate forum for complex disputes requiring a final, rather than provisional, determination and is the court to which adjudication enforcement applications are made.
Avoiding Disputes
Many disputes are caused or aggravated by failures of contract administration rather than fundamental disagreements between the parties. Parties should ensure a thorough understanding of their contractual obligations from the outset, comply strictly with notice requirements, maintain comprehensive contemporaneous records, record and agree variations promptly, and monitor payment deadlines carefully. Specialist legal advice sought at an early stage, before a disagreement escalates, consistently represents the most cost-effective form of dispute management.
