What A&B Engineering does
A&B Engineering is a privately owned UK mechanical, electrical, and plumbing (M&E/MEP) contractor headquartered in Liverpool, with annual sales of approximately £60 million and a directly employed workforce of 270+ including Plumbers, Fitters, Electricians, and Apprentices. The company designs and installs mechanical, electrical, and plumbing systems for commercial, healthcare, education, residential, hospitality, industrial, and public sector construction projects across North West England and, since 2025, Yorkshire, where it opened a new Leeds office. Its service portfolio spans mechanical systems (HVAC, ASHP, CHP, biomass, medical gases, fire protection), electrical systems (power, lighting, fire/security, PV, EV charging, data/telecom), plumbing and public health, and a Data Centre & Cooling Systems specialist offering. Revenue is earned through project-based fixed-price M&E contracts typically ranging £1.4M–£14M per scheme, awarded via competitive tendering with tier 1 main contractors including Morgan Sindall, VINCI, Wates, BAM, Kier, Willmott Dixon, Bowmer + Kirkland, Graham Construction, and John Sisk & Son.
The company operates an in-house design department with BIM Level 2 Accreditation and Autodesk Revit-based 3D modelling, alongside low carbon consulting capabilities (thermal modelling, SBEM calculations, Energy Performance Certificates) targeting BREEAM, WELL, and NABERS certifications. Certifications include ISO 9001, ISO 14001, BIM Level 2, CHAS, Constructionline Gold, PAS91 SSIP, Acclaim, RoSPA membership, and a £10M professional indemnity cover. Customer outcomes reported include 98% client satisfaction, 96% employee retention, and 11% year-on-year growth, with cumulative project wins of £500M+ over the past 10 years.
Ownership is private and employee-led: many current Directors and senior managers progressed from apprentice positions, and the firm maintains an internal succession pipeline evidenced by 2025–2026 board and associate director promotions. The go-to-market is enterprise field sales via direct appointments with main contractors and developers, supported by industry event presence (MIPIM, UKREiiF, NWRCA), a project portfolio website, and active LinkedIn engagement. Awards include the 2025 NWRCA ESG Sustainability Award, 2025 Silver Defence Employer Recognition Scheme Award, and 2024 Social Value Award with VINCI.
