Roughly a third of UK construction projects encounter delays, claims, or contractual disagreements, according to the Royal Institute of Chartered Surveyors (RICS). What separates a manageable disagreement from a project-crippling dispute often comes down to the resolution mechanism chosen, and when it is triggered.
Adjudication, arbitration, and litigation compared
Three formal mechanisms dominate UK construction dispute resolution, each with distinct cost profiles, timescales, and enforcement characteristics. The table below sets out the core differences.

| Mechanism | Typical timescale | Binding? | Key feature |
|---|---|---|---|
| Adjudication | 28 days (extendable by 14 days with referring party’s consent) | Temporarily binding until final determination | Statutory right under the Housing Grants, Construction and Regeneration Act 1996 |
| Arbitration | Months to years, depending on complexity | Final and binding (limited appeal rights) | Private, confidential process; parties select the arbitrator |
| Litigation | Often over a year in the Technology and Construction Court (TCC) | Final and binding (subject to appeal) | Public record; judge-led; formal disclosure and evidence rules |
Mediation sits alongside these as a voluntary, non-binding process. It can be effective for preserving commercial relationships, but it does not produce an enforceable decision on its own.

Economic drivers behind adjudication volumes
Most guides treat dispute volumes as a product of poor contract administration. Research published in October 2026, covering UK adjudication data from Q3 1999 to Q1 2024, tells a more nuanced story.
Construction output was a significant short-run factor associated with adjudication volumes. When the industry is busier, more referrals are made. Over the long run, the share of refurbishment and maintenance work showed a positive association with adjudications. This makes practical sense: refurbishment projects frequently involve unforeseen conditions, unclear scope boundaries, and overlapping trades.
The implication for firms is that dispute readiness should scale with market activity, not just with the complexity of individual projects. A period of sector growth does not reduce risk; it concentrates it.
TCC enforcement trends in 2025 and 2026
Adjudication only works if the losing party pays. The Technology and Construction Court has maintained a robust approach to enforcement, and recent decisions sharpen the picture in three areas.
Stays of execution and financial evidence
A party seeking to delay payment of an adjudicator’s award must do more than assert financial difficulty. In a 2026 case, a contractor argued that paying the adjudicated sum might threaten its ability to continue trading. The court found this insufficient without evidence addressing potential funding from shareholders or other sources. Bare assertions of hardship, without documentary support, will not persuade the TCC to grant a stay.
Professional negligence claims reaching adjudication
Recent TCC decisions confirm that adjudication can extend beyond familiar contractor payment disputes. In one 2026 judgment, the court considered whether a consultant’s liability for alleged over-certification could properly be referred to adjudication. Where the contract and referral permit it, adjudication may determine a consultant’s liability, not only payment claims. This widens the practical scope of the statutory regime.
Building safety and group-company exposure
Building-safety claims are increasingly intersecting with adjudication. A 2026 case examined circumstances where an award was made against an insolvent contractor. The decision highlighted that consequences may extend to connected group companies, a dimension that standard dispute-resolution guidance rarely addresses.
Contract terms that shape dispute outcomes
The choice of standard form, and the amendments made to it, often predetermines how a dispute will unfold. Three contract-level decisions carry disproportionate weight.
- Notice provisions remain the single most litigated contractual mechanism. A failure to serve a notice within the prescribed period can extinguish an otherwise valid claim for an extension of time or loss and expense, regardless of the merits.
- Payment machinery under the 1996 Act requires compliant payment and pay-less notices. Non-compliant notices create a liability for the notified sum, even where the paying party disputes the underlying valuation.
- Multi-tiered dispute clauses that require negotiation or mediation before adjudication can delay access to a binding decision. Where these clauses are poorly drafted, parties spend time arguing about whether a precondition has been satisfied rather than addressing the substantive dispute.
Contemporaneous records matter at every stage. Courts and adjudicators consistently place greater weight on evidence created at the time of the disputed event than on retrospective accounts. Programme updates, site diaries, correspondence, and photographic records all carry more evidential force than witness statements produced months later.
Early intervention and dispute avoidance in UK construction
Formal dispute resolution is expensive relative to the sums at stake in many construction projects. Two practical approaches reduce the likelihood of a referral reaching adjudication or court.
The first is early neutral evaluation, where an independent third party gives a non-binding opinion on the merits before positions harden. This works best when both parties have a continuing commercial relationship they want to preserve.
The second is structured contract administration. This means actually operating the contractual machinery, issuing notices on time, certifying properly, responding within the stipulated periods, rather than relying on informal arrangements that break down under pressure. A significant proportion of disputes escalate not because the underlying claim is complex, but because one party failed to follow the procedural steps the contract requires.
Dispute boards, more common in international projects, are beginning to appear in larger UK schemes. They provide a standing panel that can intervene at the first sign of disagreement, before the parties have committed to adversarial positions.
The data from 2026 reinforces a consistent pattern: enforcement of adjudication awards remains robust, the TCC continues to uphold the “pay now, argue later” principle, and parties that rely on procedural objections without substantive evidence rarely succeed. For UK construction professionals, the lesson is direct. The resolution mechanism matters, but the quality of records and the discipline of contract administration determine whether you enter that mechanism with a strong position or a weak one.
