What Wallace Whittle does
Wallace Whittle is an independent UK-based environmental building services consultancy founded in 1964 and headquartered in Glasgow. Following an April 2021 management buy-out, the firm has grown from 80 employees and £8m in turnover to over 200 staff and £20m in revenue, operating across nine UK offices from Aberdeen to London. It serves developers, investors, public sector bodies (notably NHS trusts), commercial real estate firms, and data centre operators with integrated mechanical, electrical and public health (MEP) engineering alongside specialist sustainability consultancy.
The core offering combines MEP design — covering HVAC, electrical distribution, lighting, fire detection, BMS and public health systems — with sustainability services such as Whole Life Carbon Assessment (WLCA), BREEAM and WELL certification support, net zero carbon pathway planning, and energy modelling. The firm maintains BIM Stage 2 certification with re-verification, enabling BIM-enabled digital coordination workflows on complex projects. Specialist capabilities include healthcare technical assurance (KSAR compliance) for acute hospitals, and data centre MEP design addressing high-density AI workloads. Internal talent development is supported through the WW:Academy four-level training programme and a degree apprenticeship pipeline.
Revenue is generated through professional consultancy fees on project-based engagements, typically delivered on multi-year contracts for enterprise and public sector clients. The go-to-market is direct and sales-led, with no channel distribution; senior hires, regional office openings and acquisitions are the primary growth levers. The customer base includes named enterprise clients (Morgan Stanley, Barclays, OVO Energy, Telreal Trillium, HFD Construction, Drum Property Group, Rapid7, King's College London, St James Quarter) alongside government commissions (NHS Lanarkshire, NHS Golden Jubilee, Driver and Vehicle Licensing Agency). The firm is pursuing an explicit growth strategy to more than double turnover within three years, supported by acquisitions (Davie + McCulloch in 2025; Petrie Buchanan announced 2026-05-14), NHS HPCCAS framework appointment, and selection for the Hunter Foundation Scale Up 2.0 initiative.
