What COOK BROWN ENERGY LTD does
Cook Brown Energy Ltd is a UK-based private limited company that provides energy and sustainability assessments, compliance calculations, and certification services for the construction sector. The firm operates in the built-environment consultancy space, supporting construction projects with the energy performance and sustainability evaluations required to meet building regulations and certification standards (such as those formerly administered under the UK's EPC/EPC regime and BREEAM/equivalent frameworks). Its offering is professional services in nature — assessments and compliance calculations delivered to construction clients — rather than a software product.
The company was founded in 2017 and currently operates with a headcount in the 11-50 range, placing it firmly in the small consultancy segment. The website domain (cookbrown.co.uk) and the "Ltd" legal suffix confirm a UK domicile. No further detail on technology stack, proprietary tooling, pricing, customer segments, partnerships, or management team was accessible from the source data; the company website returned only a loading/verification page during data collection, and no additional public disclosures were available.
The business model is professional services — fees are presumed to be project- or assessment-based, charged to construction industry clients (developers, contractors, architects, or building owners). No pricing details, ARR, customer logos, or revenue figures are disclosed. With no funding rounds, no acquisitions, no public certifications beyond the regulatory minimum for its services, and no productised offering evident, the company appears to operate as a tightly-scoped specialist consultancy with limited publicly observable growth or expansion signals.
