What cirrus plus does

Cirrus Plus Limited is a privately-held Mechanical and Electrical (M&E) engineering consultancy based at 118 Pall Mall, London, serving the UK construction industry. Founded in 2010 by Principal Director Edward Pictureon, the firm specialises in dispute resolution and expert witness services for the Technology and Construction Court alongside traditional M&E design, design review, commissioning management, contract administration, project management, site surveys, facilities audits, and environmental and sustainability advice. The firm's client base spans end-clients, contractors, architects, project managers, quantity surveyors, and solicitors across commercial, education, residential, hotels, hospitals and laboratories, transportation, and assembly/communal building sectors.

Cirrus+ monetises through professional consultancy fees on a bespoke, project-by-project basis, with no disclosed pricing, subscription, or recurring contract model. Its go-to-market is enterprise field sales built on the Principal Director's professional reputation, 30 years of building services experience, and standing as a Chartered Engineer, Fellow of CIBSE, Associate of the Chartered Institution of Arbitration, and member of the Society of Expert Witnesses, Expert Witness Institute, and Society of Construction Law. Service delivery is direct to client, primarily within London and the UK but with overseas commissions enabled by Heathrow proximity.

The firm operates at boutique scale with a single named Principal Director and undisclosed additional headcount, and holds no external funding. Its competitive positioning is built on expert witness credibility and a track record of marquee commissions including The Shard, Leadenhall Building, Heathrow, the British Museum, Natural History Museum, Bank of Tokyo, London Underground, and Norman Foster & Partners, with related sector work in healthcare, education, and hospitality.
