The Pre-Action Protocol for Construction and Engineering Disputes is the CPR specialist protocol that prescribes a structured pre-action process for construction-related disputes, including a Letter of Claim, Letter of Response and mandatory pre-action meeting, before the matter is litigated in the Technology and Construction Court.

The Pre-Action Protocol for Construction and Engineering Disputes (the C&E Protocol) is a CPR specialist protocol applying to construction and engineering disputes, including those involving professionals such as architects, engineers, project managers and quantity surveyors. It applies before proceedings are issued, typically in the Technology and Construction Court (TCC).
The C&E Protocol requires the claimant to serve a Letter of Claim with detailed particulars, the respondent to acknowledge and respond, and the parties to hold a pre-action meeting to identify and narrow the issues, consider ADR and agree any necessary process for further information exchange. The Protocol is designed to manage the complexity and document-heavy nature of construction disputes before formal proceedings.
The C&E Protocol applies to disputes arising out of construction contracts, including disputes involving professional advisers’ work on construction projects. Pure professional negligence claims against non-construction professionals are governed by the separate Pre-Action Protocol for Professional Negligence. Disputes also subject to adjudication under the Housing Grants, Construction and Regeneration Act 1996 may proceed by adjudication first, with court proceedings following on enforcement or final-account points.
The C&E Protocol is one of the specialist protocols supplementing the Practice Direction on Pre-Action Conduct and Protocols under the Civil Procedure Rules 1998. It is published with the CPR and updated periodically (the current edition was substantially revised in 2016, with subsequent refinements).
The Protocol is supplemented by the underlying substantive law including the Housing Grants, Construction and Regeneration Act 1996 (which imports the right to adjudication and mandates certain payment notification provisions in construction contracts), the Defective Premises Act 1972 (statutory duties owed in dwellings), the Building Safety Act 2022 (for higher-risk buildings post-Grenfell), and the common law of contract, tort and professional liability.
Procedurally, the TCC’s jurisdiction is set out in CPR Part 60 and the TCC Guide. The TCC is a specialist division of the King’s Bench Division, and it has the case-management expertise to handle complex construction disputes including the use of Scott Schedules, experts’ meetings and substantive case management.
Non-compliance with the C&E Protocol can attract costs sanctions under CPR 3.1(4) and the Practice Direction on Pre-Action Conduct. As with all CPR protocols, the court takes into account the conduct of the parties before proceedings when exercising its case-management discretion.
The C&E Protocol process begins with a Letter of Claim containing prescribed information: a clear summary of the facts on which the claim is based, the basis on which each claim is made, the nature of the relief claimed, identification of the contract relied upon, identification of any third parties, particulars of breach, and (if appropriate) a Scott Schedule format for itemised claims (such as defects schedules).
The respondent must acknowledge within 14 days and provide a Letter of Response within 28 days (with extension by agreement to a maximum of three months for substantial claims). The Letter of Response addresses each allegation, identifies contractual or statutory limitation defences, raises any cross-claim, and addresses ADR.
The parties must then hold a pre-action meeting (PAM), normally within 28 days of the Letter of Response. The PAM aims to identify the main issues, agree on the necessary further information and documents, consider expert evidence, and address ADR. The meeting is without prejudice and typically attended by the parties’ lead representatives and solicitors, sometimes with experts. The output is often a brief agreed statement on the next steps.
Insurance is a recurrent feature. The PI insurer of the construction professional (architect, engineer) will typically take conduct. The contractor’s own contract works and public liability insurers may be involved if site-related issues are alleged. Latent defects insurance (where present) may also be in play. Insurers may be on cover for the underlying liability and for defence costs, although this depends on policy wording.
Where parties have already used adjudication under the HGCRA 1996 to determine an interim issue, the C&E Protocol still applies if and when final-account or repayment litigation follows. Adjudication decisions are temporarily binding pending final determination; the C&E Protocol governs the road to court for the final determination.
Following the PAM, the parties either settle, agree directions for further pre-action steps (such as expert exchange), or move to proceedings. The TCC will expect substantial Protocol compliance before issue, although in time-sensitive cases (limitation, ongoing damage, urgent injunctions) commencement may precede full compliance.
Adjudication under HGCRA 1996: Most construction contracts (other than for residential occupiers) confer a statutory right to refer disputes to adjudication, with a 28-day decision and enforcement via summary judgment in the TCC. The C&E Protocol does not displace adjudication; it governs the route to court for matters going beyond adjudication.
TCC jurisdiction: The TCC handles the majority of significant construction disputes in England and Wales. It is a specialist court with judges experienced in technical evidence. Smaller construction disputes may proceed in the County Court multi-track.
Latent defects: Long limitation periods (15 years for negligence claims involving latent damage under section 14A Limitation Act 1980; 30 years for Building Safety Act 2022 dwelling claims) mean construction disputes may surface long after completion. The C&E Protocol applies whenever proceedings are contemplated.
Building Safety Act 2022: Following the Grenfell Tower fire, the BSA 2022 extended limitation periods (section 135) and created additional remedies for unsafe dwellings. The C&E Protocol applies to these claims when litigated.
PI cover for professionals: Architects, engineers, project managers and quantity surveyors carry PI cover; cover terms govern who responds and how. Construction PI is a specialist market with claims-made cover and notification provisions that interlock with the Protocol.
Contract works and public liability: Contractors hold contract works cover (for the works themselves) and public liability cover (for third-party injury and property damage). Both may be in play in construction disputes.
Insurer-funded mediation: PI and contractor liability insurers commonly fund mediation under the Protocol, viewing settlement as cost-efficient compared to TCC litigation.
A developer contracts a main contractor to build a 12-unit apartment block. The architect is engaged separately. On completion the developer discovers extensive water ingress through the curtain walling. The developer’s solicitors send a Letter of Claim under the C&E Protocol to both the contractor and the architect, alleging defective design and workmanship and claiming £2.3 million in rectification costs and consequential losses. A Scott Schedule attaches detailed itemised defects.
The contractor and architect each notify their respective insurers. The architect’s PI insurer instructs panel counsel; the contractor’s contract works insurer agrees to fund defence subject to coverage analysis. Both respond within the extended response period. A pre-action meeting takes place at the architect’s offices. Joint expert inspection is arranged; the experts produce a joint statement narrowing the contested defects to four major categories. After three months of expert dialogue, the parties mediate. A settlement is reached: the contractor pays £1.4 million (funded by contract works insurance), the architect pays £450,000 (funded by PI insurance), and the developer accepts £1.85 million in full and final settlement. No TCC proceedings are required.
