Construction Dispute Resolution UK: Your Options

Disagreements on construction projects are common, and when they escalate they can drain budgets, delay completion, and damage working relationships that took years to build. Picking the right way to resolve a dispute is often as important as the merits of the dispute itself.
Get it wrong and you may end up spending more on the process than the sum in dispute. Get it right and you can often preserve the commercial relationship while reaching a workable outcome. This guide walks through the main routes open to parties working under construction contracts in England and Wales, including adjudication, arbitration, mediation, and court proceedings.
Each has its own rhythm, cost profile, and level of formality. By understanding how they differ, you can make a more informed choice about where to take a problem when negotiation alone has not resolved it.
What this document is
Dispute resolution in construction covers the formal and informal processes parties use to settle disagreements arising out of a building project. These disagreements often involve payment, delay, defects, variations, extensions of time, or the scope of what was agreed in the contract.
The Housing Grants, Construction and Regeneration Act 1996 (as amended) gives parties to most construction contracts a statutory right to refer a dispute to adjudication at any time, which makes adjudication the default first port of call for many contractors, subcontractors, and employers. Beyond adjudication, the contract itself usually sets out whether arbitration or court proceedings apply if a party wants a final determination.
Mediation and other forms of negotiation sit alongside these processes and can be used at any stage. Choosing between them depends on factors like the value of the claim, whether you need a quick answer on cash flow, how much confidentiality matters, and whether the relationship between the parties is worth preserving.
How to use this document
- Identify the type of dispute and what you want from it. Before picking a route, get clear on what the argument is actually about and what outcome would resolve it. A payment dispute that is holding up cash flow calls for a very different approach from a complex defects claim that might take years to investigate. Write down the sum at stake, the contractual clauses involved, and what a good result looks like.
- Check what the contract says about dispute resolution. Most construction contracts, including JCT and NEC forms, contain specific clauses setting out the agreed route. Some mandate adjudication first, then arbitration, while others default to the courts. Read these clauses carefully, because launching the wrong process can waste costs and give the other side an easy procedural win.
- Consider negotiation and mediation first. Many disputes settle once each side has put its position in writing and had a structured conversation. Mediation involves a neutral third party helping you reach a voluntary settlement, and it is often far cheaper and faster than a formal decision. Courts generally expect parties to have at least considered this route before litigating.
- Use adjudication for a quick, interim-binding decision. Statutory adjudication is designed to deliver a decision within 28 days of referral, extendable by agreement. The adjudicator's decision binds the parties until the dispute is finally determined by arbitration, court proceedings, or settlement. This makes it particularly useful where cash flow needs protecting during the life of a project.
- Move to arbitration or court proceedings for final determination. If the dispute needs a final answer, arbitration offers a private, contractually agreed process, while court proceedings in the Technology and Construction Court offer a public forum with wider powers. Each has its own procedural rules, costs exposure, and appeal rights, so weigh these carefully before starting.
Common questions
Q What is adjudication and why is it so widely used in construction?
Adjudication is a statutory process introduced by the Housing Grants, Construction and Regeneration Act 1996 that lets parties to most construction contracts refer a dispute to an independent adjudicator for a decision, usually within 28 days. It is popular because it is quick, relatively affordable, and keeps cash moving during a live project. The decision is binding on an interim basis but can be challenged later in arbitration or court.
Q Is an adjudicator's decision final?
Not in the strict sense. An adjudicator's decision is binding on the parties and must be complied with, but either party can later challenge the outcome by arbitration or litigation if the contract allows. In practice, many adjudication decisions are accepted and never reopened, because the cost and effort of running a full arbitration or trial afterwards often outweighs the benefit.
Q How does arbitration differ from going to court?
Arbitration is a private process where the parties agree on a neutral arbitrator, or a panel, to decide their dispute under rules set out in their contract or a recognised institution. Court proceedings are public, governed by the Civil Procedure Rules, and heard by a judge. Arbitration can offer more confidentiality and flexibility, while courts have broader powers and established procedures for complex claims.
Q When should I consider mediation?
Mediation can be useful at almost any stage, including before formal proceedings, during adjudication, or even partway through a court case. It works particularly well where the parties want to preserve a commercial relationship, where the issues are as much about communication as about strict legal rights, or where the cost of continuing to fight would outweigh the likely gain from winning outright.
Q Which court deals with construction disputes in England and Wales?
Most significant construction disputes are heard in the Technology and Construction Court, a specialist part of the High Court based in the Business and Property Courts. TCC judges have experience of construction contracts, engineering disputes, and adjudication enforcement. Smaller claims can be brought in the County Court, but complex or high-value construction matters are usually better suited to the TCC.
Q Can I recover my legal costs in a construction dispute?
It depends on the process. In court and arbitration, the general rule is that the losing party pays a proportion of the winner's reasonable costs, although the amount recovered is often less than what was actually spent. In adjudication, each party typically bears its own costs regardless of outcome, unless the contract says otherwise. Always check your contract and take a view on costs exposure early.
Q Do I need a solicitor to start adjudication?
You do not have to instruct a solicitor, and many parties use claims consultants or handle smaller referrals themselves. That said, adjudication moves fast, and a poorly drafted notice or referral can undermine an otherwise strong case. For anything other than the simplest payment dispute, getting experienced input on how to frame the referral and present the evidence is usually worth the investment.
