What Byrne Group does

Byrne Group Limited is a UK-based integrated construction services company founded in 1969 and headquartered at 53 Great Suffolk Street, London SE1 0DB. The group delivers complex construction projects from demolition through to fit-out, operating through five wholly-owned subsidiaries: Byrne Bros. (Formwork) Ltd. (concrete frame specialist), F.B. Ellmer Ltd. (new-build, refurbishment and fit-out), O'Keefe Construction (Byrne Group) Ltd., Byrne Demolition, and Byrne Groundworks. Its service portfolio covers concrete frames, new-build, fit-out, refurbishment, demolition, groundworks, consolidation centre logistics and Design for Manufacture and Assembly (DfMA). The group is technically differentiated by top-down construction methodologies used on constrained urban sites, bespoke precast concrete solutions (including domed coffer units and permanent diaphragm wall props), BIM Level 2 processes integrated with drone-based site surveys, and lean construction methods. Certifications include ISO 9001, ISO 14001 and ISO 45001, with project-level sustainability ratings such as BREEAM Excellent (Creed Court) and BREEAM Very Good (Olive Morris House).

The group serves enterprise and government clients across commercial, hospitality, residential, infrastructure, education, light industrial, retail, and sport & leisure sectors. Its customer base spans McAleer & Rushe, Frasers Hospitality, Costain/Skanska (Crossrail), Marylebone Cricket Club, Lovell Partnership, Equinix, Curo Construction, and Lambeth College, among others.

Byrne Group generates revenue through project-based contracts procured via competitive tendering, negotiated contracts and direct client appointments. Pricing is bespoke, determined by project scope, complexity and programme, and revenue is recognised against contractual milestones. The go-to-market is enterprise field sales targeting main contractors and direct end-clients through a reputation-led approach, supported by a corporate website, sector case studies and industry publication coverage. Operations are concentrated in London and the South East, with nationwide UK delivery; the group is private and does not publicly disclose revenue. Michael Byrne is CEO and Sean Byrne is Compliance Director.
