What Counts as a Construction and Engineering Dispute?
A construction and engineering dispute arises when building works, engineering services, or related payment obligations go wrong. Common parties are homeowners, landlords, tenants, contractors, subcontractors, architects and engineers. Disputes include:
- Defects and quality issues: visible (patent) defects such as cracked plaster or leaks, and hidden (latent) defects, including structural or foundation failures that may emerge years later. As a general rule, claims must be brought within six years from the date the damage occurs. For latent damage, this period may be extended to three years from the date the claimant first knew, or ought reasonably to have known, of the damage and its cause, provided this expires later than the original six-year period (section 14A(4), Latent Damage Act 1986). Tort claims remain subject to a 15-year longstop, while claims under deed have a 12-year limitation period.
- Delays and disruption: late completion, failure to meet milestones or disruption of services.
- Payment and valuation disputes: unpaid invoices, overcharging, retention disputes and variations to contract price.
If you’re wondering “what is a construction and engineering dispute?” – it is any disagreement arising from construction or engineering work. These conflicts frequently involve complex contracts, industry standards and building regulations; early identification and documentation are vital for building a strong case.
Your Fastest Route to Resolution
- Document the problem: keep your contract, scope/specifications, change orders and snagging lists. Record defects with dated photographs or video and save emails, texts and messages. Get independent expert reports when needed.
- Notify promptly: write to the contractor or responsible party describing the issues and refer to the contract clause breached. Suggest a solution and invite them to inspect. Failing to allow the original contractor to rectify defects may limit your recovery.
- Negotiate and consider adjudicating construction and engineering disputes: many disputes settle by negotiation. Adjudication offers a 28‑day decision and is often used for payment claims or technical disagreements.
- Use ADR first: mediation or arbitration can resolve disputes before court. Mediation is low cost (around £150 per hour per person); arbitration is formal and more expensive but offers confidentiality.
- Follow the pre‑action protocol for construction and engineering disputes: if court becomes unavoidable, comply with the protocol. Send a formal letter of claim, exchange detailed responses and attend a pre‑action meeting. The court expects you to consider ADR and may impose cost sanctions for non‑compliance.
Common Causes of Construction & Engineering Law Disputes
Disputes often stem from similar root causes. Understanding them can help you avoid problems and respond effectively.
Defects and Quality Issues
Defective work is the most common trigger. It includes poor materials, shoddy workmanship, non‑compliance with building regulations, structural defects or inadequate waterproofing. Patent defects are visible at completion; latent defects appear later and may only be discovered after the defects liability period has expired. Latent defects often attract longer limitation periods (up to 15 years).
Delays and Disruptions
Projects are overrunning due to late delivery of materials, subcontractor problems or weather. Delays may lead to liquidated damages or claims for additional costs. Clear schedules and communication reduce risk.
Payment and Valuation Disputes
Late or non‑payment and valuation disagreements cause many construction and engineering disputes. Retention monies, interim payments or final accounts are common flashpoints. Keeping accurate records and using structured payment mechanisms (such as the Housing Grants Act payment notices) helps avoid conflict.
How to Resolve Construction and Engineering Disputes?
Different resolution methods suit different situations. Consider the complexity, value and urgency of your dispute before deciding.
Adjudication (Fast Resolution)
Under the Housing Grants, Construction and Regeneration Act 1996, parties to construction contracts have a legal right to adjudicate. Adjudication is the main route for resolving construction and engineering disputes where a fast decision is needed. The process begins with a notice of adjudication, followed by a referral notice with evidence and a short defence period. The adjudicator must issue a reasoned decision within 28 days, extendable by 14 days with consent. The outcome is temporarily binding and can be enforced through the Technology and Construction Court, making adjudication a fast choice for construction disputes, though the costs may exceed the value of smaller claims.
Mediation
Mediation is a facilitated negotiation. A neutral mediator helps parties explore settlement without deciding the outcome. It is flexible and confidential. The Small Claims Mediation Service offers free mediation for eligible claims under £10,000. The court can impose cost penalties on parties who unreasonably refuse mediation. Mediated settlements can include creative solutions like staged payments or remedial work, and can preserve relationships.
Arbitration
Arbitration is a private dispute resolution process where parties appoint an arbitrator (or panel) to decide the case. It is formal but allows more control over the procedure. Arbitration suits higher‑value or complex construction & engineering law disputes where confidentiality and enforceability of an arbitral award are important.
Litigation
Litigation should be a last resort. Court proceedings require strict compliance with the pre‑action protocol for construction and engineering disputes. Litigation can be slow and costly, but it may be necessary to enforce rights, particularly for complex cases or where other methods fail.
Pre‑Action Protocol for Construction and Engineering disputes (UK): What It Is and When It Applies
The pre-action protocol for construction and engineering disputes (UK) is designed to encourage early resolution and reduce the need for court proceedings. The Second Edition, introduced in 2023, applies to most construction and engineering disputes, including claims involving defects, delays and payment issues. It does not apply to the enforcement of adjudicator decisions, interim injunctions or summary judgment applications. Although parties can agree to opt out, the court expects compliance in most cases and may impose cost sanctions for serious breaches. Even disputes connected to the Building Safety Act are expected to follow the protocol before court proceedings begin.
The protocol covers most disputes relating to building, engineering, surveying and associated professional services. The main exceptions remain the enforcement of adjudication decisions, interim injunctions and summary judgment applications. Parties may agree to disapply the protocol, but they must make this clear to each other. While the Building Safety Act extends limitation periods for certain construction defects to 15 years, and up to 30 years retrospectively, claimants are still required to follow the pre-action protocol before starting litigation.
The Pre-Action Timeline (What Happens Before Court)
If you plan to issue a construction defect claim, the pre-action protocol for construction and engineering disputes requires you to follow a short legal sequence first. Skipping any step can weaken your position and increase your costs. This is the required flow.
Step 1: Letter of Claim
Your claim starts with a letter of claim. This letter explains what went wrong, identifies the contract terms that apply, sets out what you are claiming back, and lists the evidence you rely on. It must also confirm whether you are requesting a protocol referee (a neutral expert who helps identify and narrow technical issues before court). This document fixes your legal position from the start.
Step 2: Acknowledgement (14 days)
The other party then has 14 days to confirm that your letter has been received. If they fail to acknowledge it, that lack of response can be relevant later in the dispute.
Step 3: Letter of Response (28 days)
Within 28 days, the other side must provide a letter of response or a counterclaim. This must state which parts of your claim are accepted, which are disputed, what further information is required, and who their experts are. This response defines the shape of the dispute going forward.
Step 4: Pre-Action Meeting (21 days)
Within 21 days of the response, both parties must attend a pre-action meeting, either online or in person. Everyone attending must have the authority to settle. The meeting is used to narrow the issues, explore settlement options, consider ADR, and decide what happens next. Everything discussed is without prejudice and cannot be used later in court.
Keep It Proportionate
Courts expect the process to remain proportionate. Letters should be concise, meetings should be focused, and although each stage can be extended by agreement for up to 28 days, the overall process should move forward promptly.

Deadlines for Construction Defect and Dispute Claims
Time limits differ by the type of contract and nature of the defect. Missing a deadline can bar your claim, so keep track.
- Simple contracts: 6 years from breach or practical completion.
- Deeds: 12 years from breach.
- Latent defects: long‑stop period of 15 years from completion.
- Building Safety Act claims: 15 years for claims accruing after 28 June 2022 and up to 30 years retrospectively.
- Limitation periods and the pre‑action protocol: starting the protocol does not stop limitation; if time is short, commence court proceedings and ask the court to stay them while the protocol is followed.
What Can You Realistically Get If You Succeed?
If you prove your case, the remedies include:
- Rectification (cost of repair): the usual measure of damages is the reasonable cost of repairing the defect. Courts aim to put you in the position you would have been in had the contract been properly performed.
- Diminution in value: if repair is disproportionate or impractical, damages may be based on the reduction in property value.
- Consequential losses: you may claim for loss of rental income, business disruption or additional expenses if they are clearly connected and proved.
- Specific performance: the court may order the contractor to fix the defect. However, because of the duty to mitigate, it is often better to arrange remedial works yourself and recover the cost.
