FLATT CONSULTING LIMITED

What FLATT CONSULTING LIMITED does

FLATT Consulting Limited is a UK-based building services engineering (M&E) and sustainability consultancy with offices in Caterham, Surrey (headquarters) and London (South Bank). The firm delivers integrated mechanical, electrical, lift, low-carbon, and sustainability design services from concept through technical design and post-completion certification, supported by accredited BREEAM, EPC, and Home Quality Mark assessors, building performance simulation, and district heating network design capabilities.

The company operates a professional services, project-based revenue model targeting enterprise clients across commercial real estate, residential development, hospitality, education, film/TV studios, and government sectors. Notable clients include Derwent London, Berkeley Homes, PineBridge Benson Elliot, UCL, Universal Music Group, Bristol City Council, and Ealing Studios. FLATT differentiates through demonstrable credentials — a 22% market share of BREEAM 'Outstanding' commercial projects in Greater London (2025/2026) and pioneering work such as the first Net Zero Carbon recording studios at Ealing Studios — but provides no public pricing, headcount, or revenue data.

FLATT is a privately held, independently owned UK limited company with no disclosed investors, funding rounds, parent company, or subsidiaries. Its competitive positioning rests on technical specialization in sustainable building certification and low-carbon systems design rather than scale advantages, and the firm has not pursued geographic expansion outside the United Kingdom.
