MEP engineering

Independent building services expertise for complex disputes
Building services are critical to the performance, safety and operation of modern buildings, and issues involving mechanical, electrical and public health systems are often central to construction disputes.

Our MEP engineering expert witness team provides clear, independent and technically rigorous opinion to help legal teams, clients and tribunals understand and resolve complex building services disputes.

We investigate MEP issues, establish the relevant facts and deliver well-reasoned expert evidence. Our reports translate highly technical subject matter into clear, concise analysis, supporting informed decision-making throughout the dispute resolution process.

• Experience across building services systems and project delivery

  Our experts bring practical experience across mechanical, electrical and public health engineering, having designed, commissioned, assessed and investigated building services systems in technically demanding sectors. Our work spans healthcare, residential, commercial, education, infrastructure, heritage, laboratory and industrial projects, as well as mixed-use developments and low-carbon energy schemes.

  A significant proportion of building services disputes turn on whether an issue arose from design, installation, commissioning, operation or maintenance. Our experts are experienced in separating these causes and identifying the true reason for system failure or underperformance.

  Building services issues rarely exist in isolation. Working alongside specialists in architecture, structural engineering, fire engineering and building surveying, we understand the wider project interfaces, design responsibilities and technical interactions that often sit at the heart of complex disputes.

• Clear analysis of MEP defects, performance and responsibility

  We advise on disputes spanning MEP system failures, defects and performance issues, through to heating and cooling systems, heat pumps, low-carbon energy installations, district heating networks and energy centres. This extends to water quality, legionella-related issues, escapes of water and drainage failures, electrical distribution, power resilience and standby generation, smoke control and fire-rated services, and building management systems, commissioning and handover. We also advise on professional negligence, design responsibility, coordination and compliance with Building Regulations and industry standards.

  Our experts quickly identify the information that matters, helping legal teams focus on the issues most likely to influence the outcome of a dispute. We provide independent opinions on causation, compliance, responsibility and the standard of care expected of a reasonably competent professional.

• Clear reports and practical advice

  Clients instruct us for our combination of technical expertise, practical building services experience and clear communication. Whether addressing water quality failures, escapes of water, standby generator issues, fire-rated ductwork, smoke control systems or major heating and cooling infrastructure, our analysis remains calm, objective and evidence based.

  Whether instructed on a focused technical issue or a major multidisciplinary dispute, we provide independent, robust and proportionate building services evidence that helps clients navigate complex engineering matters with confidence.
