PSH

What PSH does

PSH Consulting Ltd. is an independent, founder-owned mechanical and electrical (MEP) design consultancy headquartered in London, founded in 2002. The firm provides full MEP building services — mechanical, electrical, public health engineering, and AVIT — alongside a portfolio of specialist advisory services covering Energy & Sustainability, Building Information Modelling (BIM using Autodesk Revit MEP and Navisworks), Vertical Transportation, Fire safety, Acoustics, and EPC / Net Zero advisory. PSH delivers these services across new build and refurbishment projects for property developers, hotel operators, retailers, financial institutions, and commercial occupiers, with a portfolio spanning hospitality (Dorchester Collection, Marriott, NOBU, Lanesborough), commercial offices (HSBC, Barclays, Nvidia, Trainline), residential build-to-rent (Greystar, LGIM, Quintain), and retail (Louis Vuitton, Harrods, John Lewis, Waitrose).

Underlying technology is centered on 3D BIM parametric modeling for inter-disciplinary design coordination, clash detection, and virtual walk-throughs, with MEP models integrated alongside architectural and structural models. The firm operates from three offices (London, Wokingham, Londonderry/Derry) and serves projects across the UK, Ireland, and mainland Europe.

Revenue is generated through project-based professional services fees for design, project management, and technical advisory work. Go-to-market is relationship-driven enterprise sales: projects are predominantly won via recommendations, repeat business from long-tenured clients, and active engagement at industry events such as MIPIM and the Annual Hotel Conference. There are no publicly disclosed pricing models; engagements are bespoke and negotiated per project. The senior management team has worked together for over 25 years, with founder Peter Scholes transitioning to Chairman in January 2020 and Andrew Haskins assuming the Managing Director role.
