What i3Works does
i3Works is a UK-based independent management consultancy founded in 2014 and headquartered in Bristol (with a registered office in East Kilbride, Scotland). It specialises in Portfolio, Programme and Project Management (P3M), Project Controls, Business Change and Transformation, Digital Services, Architecture, Service Management, Assurance, and Cyber Security, and positions itself as one of the top project management consultancies in the UK. The firm operates an i3Group structure with three wholly-owned subsidiaries — i3Secure (cyber security and information assurance), i3NetZero (climate, ESG and sustainability), and i3Data (data services) — alongside the i3Institute training brand and the Mi3 Veterans Support Network that channels ex-military talent into billable roles.
The company's core service lines are delivered by what it describes as an embedded 'One Team' model, in which consultants are seconded into client organisations alongside military, civil servants and third-party suppliers. It holds ISO 9001, 14001, 27001 and 44001 certifications, Cyber Essentials Plus, and approved supplier status on the HM Government G-Cloud, Crown Commercial Service, NHS Shared Business Services, and Digital Outcomes and Specialist frameworks. It also has a 12-month Fast Track Consultant graduate programme, the i3Institute for continuous professional training (APM PMQ, MSP, AgilePM, SAFe 5, ITIL v4), and partnerships with technology providers including Verto (PPM software, 2025), Hornbill (ESM, 2023) and Dell Technologies.
The business model is pure professional services: revenue is generated through billable consultant days and project-based engagements with UK enterprise and public sector clients. The GTM is direct enterprise sales via account directors and a specialist defence team led by a CRO with 26 years of Royal Signals experience, supplemented by approved government framework channels. The customer base is concentrated in UK central government and defence — including the Cabinet Office, Home Office, Ministry of Justice, Ministry of Defence, Defra, NHS, Nuclear Decommissioning Authority, and a small number of private sector clients such as Manchester Airport. The firm reported turnover of £35M as of 2025 (per its Teamtailor careers page) and 240 co-workers, with 80+ consultants UK-wide. It has no disclosed external equity backing, suggesting founder/management ownership and organic growth.
