6 Essential Insights into Adjudication & Dispute Resolution Services in the UK for 2026
Adjudication referrals reached a record 2,264 between May 2023 and April 2024. That figure counts referrals received by participating adjudicator nominating bodies (King’s College London, 2024). The figure illustrates the significant role adjudication continues to play in resolving construction disputes.
You may be chasing an unpaid application. Your final account may still be open months after completion. Or your client may keep rejecting your variations.
Unresolved disputes can tie up cash, management time and working relationships. Many teams only look for construction dispute advice once positions have hardened.
In this guide, you will learn how adjudication works, how to reduce the risk of disputes, and how to approach final account disagreements. We explain each route in plain terms.
1. What Are Adjudication & Dispute Resolution Services in the UK?
Adjudication is a statutory dispute resolution process designed to produce a rapid decision. In Great Britain, the Housing Grants, Construction and Regeneration Act 1996 (the “Construction Act”) gives this right to parties in qualifying construction contracts. Northern Ireland has a separate framework under the Construction Contracts (Northern Ireland) Order 1997, which has very similar adjudication provisions.
Construction adjudication is a statutory process for resolving disputes under qualifying UK construction contracts. An independent adjudicator considers both parties’ submissions and normally decides within 28 days of referral. The decision is binding until the dispute is finally determined by legal proceedings, by arbitration (where applicable) or by agreement. It is commonly used for payment, variation and delay disputes.
Supporting detail: Under Section 108 of the Construction Act, a party may give notice of adjudication at any time. The statutory procedure requires the adjudicator to be appointed and the dispute referred within 7 days of that notice. The 28-day period can be extended by 14 days with the referring party’s consent, or longer if both parties agree (Section 108, Housing Grants, Construction and Regeneration Act 1996, legislation.gov.uk).
Who can use adjudication?
Contractors, subcontractors, consultants and employers can refer disputes under qualifying contracts. Contracts with a residential occupier fall outside the statutory right under Section 106. The contract itself may still include adjudication terms.
What if the contract is silent?
If a qualifying contract does not contain compliant adjudication terms, the relevant provisions of the Scheme for Construction Contracts (England and Wales) Regulations 1998 apply in England and Wales.
2. How Does Construction Dispute Avoidance Reduce Risk?
Construction dispute avoidance puts clear processes in place early, before disagreements turn into formal claims. This is why conflict avoidance and dispute resolution in construction are increasingly considered together.
Construction dispute avoidance is a set of proactive steps that reduce the chance of disagreements becoming formal disputes. It relies on clear contract documents, timely notices, accurate cost reporting and open communication. These measures can be particularly valuable on projects with frequent variations, tight programmes or multiple subcontract packages.
Supporting detail: Although this evidence is from North America rather than the UK, Arcadis’s 2025 review identified contract and specification reviews, good communication and risk management among the most effective dispute avoidance techniques (Arcadis, Construction Disputes Report, 2025).
Use your contract’s early warning tools
NEC4 includes early warning procedures and an optional Dispute Avoidance Board (Option W3). JCT forms contain specific payment and notice mechanisms. Check the timescales in your own contract and apply them consistently.
Keep cost records up to date
Monthly tracking of variations, daywork and valuations creates a reliable audit trail. Good records provide important evidence when payment or valuation issues arise. They are central to effective construction cost management and to avoiding disputes in construction.
Start at tender stage
Many problems begin before work starts. Asking the right construction estimating and tendering questions helps you spot unclear scope and risk early.
3. What Causes a Building and Construction Dispute?
If you know the common triggers of a building and construction dispute, you can target your risk controls. Early building dispute advice at the first warning sign can help parties resolve issues before positions harden.
A building and construction dispute is a disagreement between project parties over money, time, quality or contract obligations. It often begins when a payment, variation or extension of time is rejected or not responded to. Common subjects include unpaid applications, disputed variations, delay claims, defects and final account valuations.
Supporting detail: KCL’s 2024 report identified inadequate contract administration (50%) and lack of competence among project participants (42%) as the two leading reported causes of disputes (King’s College London & The Adjudication Society, 2024).
Common triggers to watch
- Missing or late payment notices and pay less notices
- Instructions given verbally but not confirmed in writing
- Extension of time claims without programme evidence
- Scope changes priced after the work is complete
4. How Do You Approach Construction Final Account Disputes?
Construction final account disputes often involve significant sums. Variations, loss and expense and contra-charges can keep an account open long after completion. A structured approach helps narrow the issues.
A construction final account dispute is a disagreement over the total sum due under a contract. It typically combines the contract sum, variations, loss and expense, and any deductions. Depending on value and complexity, parties may resolve it through negotiation, mediation, expert determination, adjudication or final proceedings.
Supporting detail: In KCL’s 2024 survey, 38% of respondents named true value final account disputes as a common subject of adjudication (King’s College London, 2024). In S&T (UK) Ltd v Grove Developments Ltd [2018] EWCA Civ 2448, the Court of Appeal addressed payment regimes. It confirmed that where a notified sum is payable, the paying party must pay it before pursuing a true value adjudication. The judgment indicates the principle can also apply to final payments.
Step 1: Rebuild the account line by line
Reconcile each variation against instructions, measured quantities and agreed rates. Our guide on finding key evidence for contract variations shows what to collect.
Step 2: Separate agreed items from disputed items
Narrowing the gap focuses any negotiation or referral on the real issues.
Step 3: Consider the right route
The best route depends on the contract, the value, the complexity and the urgency. Take advice on the options before committing to a formal process.
5. Which Dispute Resolution in Construction Contracts Suits Your Project?
No single route suits every dispute. The right choice depends on value, urgency, relationships and whether you need a temporarily or finally binding outcome. For a wider overview, see our guide to construction dispute resolution in the UK.
Dispute resolution in construction contracts is the process parties use to settle disagreements. UK construction contracts may provide for adjudication, mediation, arbitration and litigation. The appropriate route depends on the contract, the nature of the dispute, its urgency and whether the parties need a temporarily or finally binding determination.
| Method | Timescale | Outcome | Often considered for |
|---|---|---|---|
| Negotiation | Varies | Binding only if agreed | Early, straightforward disagreements |
| Mediation | Varies | Binding only if a settlement is signed | Preserving working relationships |
| Adjudication | 28 days from referral (extendable) | Temporarily binding | Payment, variation and valuation disputes |
| Arbitration | Varies by dispute and procedure | Final (where the contract provides for it) | Parties preferring a private process |
| Litigation (TCC) | Varies by dispute and procedure | Final, subject to appeal | Points of law and complex claims |
Supporting detail: Before issuing a claim in the Technology and Construction Court (TCC), parties should normally follow the Pre-Action Protocol for Construction and Engineering Disputes. This includes a letter of claim and a pre-action meeting (Ministry of Justice, Civil Procedure Rules).
6. How Do You Choose Adjudication & Dispute Resolution Services in the UK?
Evidence and quantum play an important part in any construction dispute. When comparing construction dispute resolution services, look for commercial, technical and contractual knowledge together.
Construction dispute resolution services are professional services that help parties prepare, present or respond to construction claims. They can include claim preparation, quantum analysis, delay analysis, adjudication support and expert reporting. Contractors, subcontractors and employers commonly use them for payment, variation and final account disputes.
Supporting detail: Almost 20% of referrals in the 2024 report used low-value or fast-track adjudication procedures (King’s College London, 2024). This shows adjudication is also used for smaller claims.
Case study: Recovering statutory interest on late payments
Challenge: The client was paid late on a consistent basis. Recovering the statutory interest due required a formal adjudication.
Our approach: Quentessential Surveying represented the client throughout the adjudication. We prepared and pursued the statutory interest claim and provided contractual and commercial support.
Outcome: The matter settled for approximately £7,265, including recovery of the adjudicator nomination fee.
Statutory interest on late commercial payments is set by the Late Payment of Commercial Debts (Interest) Act 1998. Read the full late payment adjudication case study.

Frequently Asked Questions
How long does construction adjudication take in the UK?
The adjudicator must normally decide within 28 days of referral. This can be extended by 14 days with the referring party’s consent, or longer if both parties agree.
Is an adjudicator’s decision final?
No. It is binding until the dispute is finally determined by legal proceedings, by arbitration (where the contract provides for it or the parties agree), or by agreement.
Can a homeowner be taken to adjudication?
The statutory right to adjudicate does not apply to contracts with residential occupiers. A contract may still include its own adjudication terms.
Does the Construction Act apply in Northern Ireland?
No. Northern Ireland has its own framework under the Construction Contracts (Northern Ireland) Order 1997, which contains similar adjudication provisions.
What is the difference between adjudication and mediation?
An adjudicator decides the dispute. A mediator helps the parties reach their own settlement, which is binding only once they agree it.
Conclusion
Adjudication gives parties to qualifying UK construction contracts a route to a rapid, temporarily binding decision. Clear records, timely notices and sound contract administration reduce the risk of disputes. Choosing the right route depends on your contract and the nature of the dispute. As our late payment case study shows, adjudication can also be used for smaller claims. Experienced adjudication and dispute resolution services in the UK can help you assess your position, organise evidence and manage payment, variation and final account disputes.
