Construction Adjudication Timeline: What Happens After a Payment Dispute

When a payment dispute escalates, speed becomes the main issue. Adjudication exists to deliver a fast interim decision path, but only if your records and timeline control are strong.

This guide explains the practical sequence and where subcontractors usually lose momentum.

Why adjudication exists in construction contracts

UK construction legislation requires contracts to provide a right to refer disputes to adjudication at any time. Where contract terms do not comply, Scheme provisions apply.

In payment disputes, that speed is often the difference between protecting cash and carrying avoidable debt.

Typical adjudication timeline (high level)

Stage 1: Dispute crystallises

A payment issue is formally in dispute, usually after notice/payment process breakdown.

Stage 2: Notice and referral

The matter is referred under contract/Scheme process with supporting documents.

Stage 3: Adjudicator appointment and submissions

Both parties submit position and evidence.

Stage 4: Decision window

Under Scheme default framework, the adjudicator decision timeline is typically measured in weeks, not months, with specific default periods in the legislation-backed process.

Stage 5: Payment/compliance action

Parties then act on decision outcomes while preserving rights for later final determination if needed.

Practical timeline controls for subcontractors

1) Build your evidence file before a dispute

Do not wait for dispute stage. Keep a clean record of:

• applications
• notices
• valuation backup
• correspondence

2) Keep a notice chronology

Date control is central in payment disputes. One timeline view should show all due dates, notices, and payment events.

3) Define one adjudication owner internally

One person should coordinate advisers, documents, and deadlines.

4) Prioritise clarity over volume

A short, well-structured evidence pack is better than a large unindexed archive.

How this links to everyday payment admin

Teams that run disciplined monthly payment administration generally perform better in disputes because the evidence trail already exists.

That means your monthly process is not just admin, it is dispute readiness.

Frequently asked questions

Is adjudication a final determination of all issues?

It is often a fast interim decision route under contract/statutory framework. Parties may still pursue final determination routes later depending on contract and dispute context.

How fast is the process usually?

The Scheme framework is designed for rapid decision windows. Exact timing depends on route, scope, and agreed extensions.

What is the most common subcontractor weakness in adjudication?

Poor notice chronology and fragmented valuation evidence.

Should small firms still prepare for adjudication risk?

Yes. Smaller firms are usually more exposed to cash disruption from payment disputes.
