CADR Adjudication

What is adjudication?

Adjudication is the statutory process for attaining enforcement of debt in construction.

​Adjudication is more prevalent in the construction industry than in other commercial sectors. That is mainly because parties to a construction contract have a statutory right to refer a dispute to adjudication.

​The automatic right to refer disputes to an adjudicator was introduced in The Construction Act, 1996. Before that, there was a feeling that when a payment dispute arose, for example, many of the smaller businesses, suppliers and contractors involved in the building trade were at the mercy of larger organisations and developers with whom they had contracted. Larger businesses could better afford to go through lengthy and expensive legal proceedings than smaller contractors who could often end up failing to recover monies due to them.

​Adjudication has become a common way to resolve such disputes. It is a process that those entering contracts in the building or construction industry cannot opt-out of. If there is no mention of adjudication on a contract, it will be an implied term. Moreover, it is speedy: an adjudicator is required to decide matters referred to him or her within 28 days.

One thing to remember is that adjudication is a dispute resolution method that settles matters on an interim or temporary basis. Decisions are binding – but only until the dispute is determined by litigation or by agreement further down the line.

When is adjudication appropriate?

The Construction Act allows a party to a construction contract to refer a dispute to an adjudicator ‘at any time’. Typical claims might be about:

  • Non-payment of monies due for stages of a development
  • Delays to construction
  • Requests for extensions of time
  • Poorly executed and defective work
  • Clarification of the scope of a project

More complex contractual issues and negligence claims may also be referred to an adjudicator, even though the process was initially designed to deal with relatively straightforward claims on an urgent basis.

Very often, the matter referred to adjudication is a standalone issue. A dispute might be holding up a building project or causing cash-flow issues for one party to the contract. By accepting the adjudicator’s jurisdiction and decision, the parties can continue to work. Often the ruling will only be a temporary solution, enabling the development to continue until a more permanent outcome can be found.

When is adjudication not appropriate?

Not every disagreement is suitable for adjudication. Remember that the adjudication process in construction disputes has been developed to provide quick, practical solutions. If a dispute is particularly complex, the parties may agree to court proceedings or arbitration. It is often worth seeking professional advice on the cost consequences of adjudication if you proceed.

If the case is involved, complex issues adjudication costs will be higher. Furthermore, as we discuss below, even if you are successful, you have less opportunity to recover these costs than if you go to court.

How do you know if you have a construction contract?

The right to adjudication we are examining here applies to ‘construction contracts that are in writing. The Construction Act, 1996 describes a construction contract as an agreement to do any of the following:

  • Carry out construction operations.
  • Arranging for construction operations to be done by others, for example, by using a subcontractor
  • Provide labour for construction operations.

‘Construction operations’ is a broad term, covering everything from building, maintenance, demolition or repair of temporary or permanent buildings.

In many cases, it will be evident whether an agreement is a construction contract or not. If you are uncertain, it is good to seek specialist legal advice early on to know what the available remedies are. And it matters. In the 2014 case of Savoye and Savoye Ltd v Spicers Ltd, a total of £400,000 in legal fees was incurred, establishing that, on the face of it did not seem to be a construction contract at all, was, and could be subject to the adjudication process.

Suppose it turns out your agreement is not a construction contract. In that case, you and the other contracting party can still elect to use the adjudication procedure.

​Critical steps in the adjudication process

The adjudication process is designed to be clear-cut and efficient. There are tight time limits to observe and conditions to satisfy before one party can start the process. The process can be extended by agreement, but briefly, the timeline is as follows:

Before you begin

Check that there is a right to adjudication: does the dispute arise out of a construction contract? Ensure the claim’s details have been brought to the other side’s attention and that the claim has been rejected or ignored. (This is known as the ‘crystallisation’ of the claim.)

Beginning the process

The party bringing the claim (the referrer) serves a Notice of Adjudication. This is followed by a Referral Notice that contains full details of the claim.

Within seven days

Agree to an adjudicator and settle the terms and conditions of the adjudication. Any dispute over the right to refer the dispute to adjudication should be raised now.

Between seven and 14 days

The responding party serves a Response (effectively a defence).

Within seven days

Referrer replies, and there is an opportunity for the responder to make further representations.

By day 28

Adjudicator reaches a decision.

Enforcing an adjudicator’s decision

The adjudicator’s decision is binding. If one side does not comply, enforcement procedures are available through the court. The Technology and Construction Court (TCC) – an arm of the High Court – is the correct forum for enforcement actions to begin.

Cumbersome enforcement procedures would undermine the whole rationale behind adjudication – to provide a speedy way to resolve construction disputes. So, a bespoke procedure has been developed that aims to fast-track cases of this nature.

A party seeking to enforce an adjudicator’s decision should begin proceedings under the Civil Procedure Rules. The specific procedure to adopt will depend on whether the party seeks a monetary judgment or declaratory relief where the court makes an official declaration about the case. An application for summary judgment should accompany the claim.

​Challenge the enforcement of an adjudicator’s decision.

Challenging an adjudicator’s decision – and its enforcement – should only be done following specialist legal advice. A successful challenge is rare. That is because – as we have mentioned – an adjudicator’s decision is binding only until the dispute is litigated or arbitrated fully. To ensure the adjudication scheme remains effective, courts will go to some length to ensure enforcement.

Case law in this area demonstrates that enforcement is sanctioned even where the adjudicator has made a factual mistake or has misapplied the law.

That said, it is possible to challenge a decision because the adjudicator did not have jurisdiction or power to adjudicate. For example, if:

  • There was no written construction contract.
  • The dispute had not crystallised.
  • The correct procedures were not followed in appointing the adjudicator.
  • matters of rectification or misrepresentation lay outsidethe adjudicator’s jurisdictionalthreshold.
  • It is also possible to argue that the adjudicator was biased in favour of one party or did not give enough reasons for the decision.

Can the enforcement of an adjudicator’s decision be deferred?

As we have pointed out, the whole adjudication process as applied to construction contracts aims to find quick solutions to disputes that might otherwise become bogged down in lengthy litigation. Delays caused by litigation can have substantial knock-on consequences for the rest of a building project and parties uninvolved in the dispute. So, it would make little sense if enforcement of a decision by an adjudicator could be delayed for any length of time. In one of the most critical cases in this area, Wimbledon v Vago (2005), the court confirmed this. It reiterated that the execution of adjudication decisions is contrary to the Construction Act’s principles, 1996. They should be allowed only in limited situations, for example, if the contractor against whom an order to pay money was made is insolvent.

In 2018 the principles set out in Wimbledon v Vago were extended to suggest that a stay of execution may be permitted where there are grounds of suspected fraud. The party seeking a delay in executing the adjudicator’s decision produces credible evidence that the party that succeeded in the adjudication may attempt to dissipate any monies received from the unsuccessful party so that they cannot be repaid if the adjudicator’s decision is later overturned in litigation or arbitration.

Can adjudication be withheld?

Parties to a construction contract cannot opt-out of adjudication. Furthermore, suppose there is no reference to the contract process. In that case, the provisions of the Scheme for Construction Contracts, 1998 are implied. A party that receives a Notice of Adjudication may, of course, challenge the adjudication process by arguing, for example, that the:

The contract in question is not a construction contract.

The dispute that forms the basis of the notice has not yet crystallised, so adjudication is premature.

  • An adjudicator has not been appropriately appointed.
  • The dispute has already been adjudicated.

Adjudication vs arbitration

​Arbitration is another form of resolving disputes often used in construction disputes. Parties appoint an arbitrator who makes an award that is binding on the parties. Adjudication and arbitration have much in common (they are private, flexible alternatives to court, for example). Nevertheless, there are significant differences, and each process has pros and cons. We have set out a summary of these below.

Length of proceedings

As we have seen, adjudication is fast, which takes 28 days from start to finish (longer if agreed between the parties). On the other hand, arbitration has a much more judicial feel about it and can take months or years to run its course.

Consideration of issues

Because of the compressed timescale, adjudication may not thoroughly examine all the issues. For particularly complex disputes involving several parties, arbitration allows for a fuller examination of the issues.

Legal fees

​It is quicker and usually involves a standalone dispute; adjudication costs can be much lower than arbitration costs. Arbitration is a more formal process. Each side presents a case, disclosing different categories of evidence and going through several procedural steps. One advantage of arbitration is the possibility of recovering legal costs from the other side. This is not available in adjudication, where each side usually bears its costs.


​An arbitrator has a broader range of legal remedies at his or her disposal than an adjudicator. Adjudication usually results in a monetary award or a remedy dictating timescales within which a contractual element must be performed.

What does adjudication cost?

​Adjudication is a short process, so exposure to costs is limited. However, because each party usually pays its legal fees, the cost of adjudication can be a significant consideration. It is not easy to be precise about actual costs, as each case will depend on its particular facts. Nevertheless, expenditure to bear in mind includes:

Adjudicator’s fee – Adjudicators charge an hourly rate, usually between £200 and £300 plus VAT. Critically, a responding party may well have little say over an adjudicator’s appointment or the level of fees because the referral notice is issued before the responding party knows what fees the adjudicator is seeking. Besides, each party will be jointly liable for the adjudicator’s fees. If one side does not pay, the adjudicator can claim all their fees from the other.

The fee to the professional body that nominates the adjudicator.

Fees to your professional advisor – Payment to a specialist construction lawyer to advise you throughout the process. It is unlikely that you will recover these fees even if you are successful in the adjudication.

How long does adjudication take?

The adjudication procedure follows a timetable of 28 days. This can be extended to 42 days or longer by agreement between the parties.
