1. Start with a clear brief

Many disputes originate in unclear requirements:

Be specific about what you want

Vague briefs lead to misunderstanding. “Refurbish the building” means different things to different people. Specify:

  • What spaces are included
  • What standard of finish
  • What functional requirements
  • What constraints exist
  • What’s excluded

Get design resolved before construction

Changes during construction are expensive and contentious. Investing in proper design before starting saves money and arguments later.

Document everything

Verbal agreements are forgotten or remembered differently. Put the brief in writing. Confirm understanding before work starts.

2. Use appropriate contracts

The right contract prevents disputes:

Standard form contracts

JCT and other standard forms have been refined over decades. Their terms are understood and balanced. Bespoke contracts often contain problems.

Match contract to project

Use Minor Works for small projects, more detailed forms for complex ones. Wrong contract = wrong procedures = disputes.

Don’t over-amend

Standard contracts are balanced. Heavy amendments shift risk and often create unintended consequences. Contractors price for transferred risk — or ignore it and dispute later.

Read the contract

Both parties should understand the terms. Procedures exist for a reason. Follow them.

3. Appoint professionals appropriately

Professional involvement prevents problems:

Independent contract administration

Having an independent Contract Administrator (not the contractor) protects your interests. They certify payment independently, manage variations properly, and ensure contract procedures are followed.

Clear roles and responsibilities

Who does what should be unambiguous:

  • Who designs?
  • Who specifies?
  • Who administers?
  • Who inspects?
  • Who certifies?

Unclear responsibilities create gaps where problems develop.

Appropriate expertise

Use professionals experienced in the type of project you’re undertaking. A domestic extension isn’t the same as commercial refurbishment.

4. Manage variations properly

Changes are the leading cause of construction disputes:

Authorise before work proceeds

No change should happen without written instruction from the Contract Administrator. Contractors who just do things and invoice later create disputes.

Agree costs upfront where possible

For significant variations, agree the cost before instructing the work. Arguing about price afterwards is more difficult.

Keep records

Document every variation: what changed, why, when instructed, what was agreed about cost. Without records, disputes are inevitable.

Minimise variations

Better design reduces changes. Every variation is an opportunity for disagreement about scope and cost.

5. Get payment right

Payment disputes derail projects:

Certify independently

Payment certificates should come from an independent professional, not the contractor. They assess work done and certify what’s due.

Follow contract payment terms

Construction contracts have specific payment provisions (application, certification, payment notice, pay less notice). Follow them precisely.

Don’t overpay

Paying ahead of work puts you at risk. If the contractor fails, you’ve paid for work you don’t have.

Don’t underpay

Withholding legitimate payments damages relationships, affects cash flow, and can lead to suspension of work (a statutory right for contractors).

6. Communicate effectively

Poor communication breeds disputes:

Regular meetings

Progress meetings (weekly or as appropriate) keep everyone informed and surface issues early.

Written records

Minutes of meetings, confirmation of decisions, records of discussions. Verbal agreements are forgotten.

Raise issues early

Small problems become big problems if ignored. Address concerns when they arise.

Professional tone

Construction is stressful. Keeping communication professional, even when frustrated, prevents escalation.

7. Monitor quality during construction

Catching defects early prevents disputes:

Regular inspections

Don’t wait until completion to look at work. Inspect during construction when problems are cheap to fix.

Clear specifications

Workmanship should be measured against clear standards. Vague specifications lead to disagreement about what’s acceptable.

Defects registers

Track issues found during construction. Ensure they’re addressed before they’re built over or become expensive to remedy.

8. Handle completion properly

The end of a project is when many disputes crystallise:

Clear practical completion criteria

What constitutes practical completion should be clear. Work substantially complete and fit for occupation — not perfect, but usable.

Proper snagging

Systematic snagging (listing defects for remedy) rather than ad hoc complaints. Give the contractor a clear list and reasonable time.

Defects liability period

Use the defects period properly. Track issues that emerge, notify the contractor, ensure remedy.

Final account

Agree the final account properly, accounting for all variations and adjustments. Leaving it open creates future disputes.

9. Document everything

Good records prevent and resolve disputes:

What to keep:

  • Contract documents
  • All instructions (written)
  • Variation records
  • Payment applications and certificates
  • Site meeting minutes
  • Correspondence
  • Photographs of work in progress
  • Inspection records

Why it matters:

If a dispute arises, the party with better records usually prevails. Memory is unreliable. Documents are evidence.

10. When disputes arise

Even with good management, some disputes occur:

Address early

Small disagreements can often be resolved through discussion. Left to fester, they become entrenched positions.

Use contract procedures

JCT contracts have dispute resolution provisions. Follow them before escalating.

Consider ADR

Mediation, adjudication, expert determination — often faster and cheaper than court.

Preserve relationships

You may need to work together to finish the project. Scorched-earth approaches may feel satisfying but often make things worse.
