What Imtech UK does

Dalkia UK (formerly Imtech UK) is a UK technical and energy services provider operating as a wholly-owned subsidiary of EDF Group, one of the world's largest energy companies. The company delivers four integrated service lines — Engineering (mechanical & electrical, specialist services, design & build), Facilities Management (planned and reactive maintenance, integrated building services, energy management), Energy Services (decarbonisation and energy efficiency projects covering feasibility, design, build, finance, operate and maintain), and Advanced Systems Integration (automation, control systems, instrumentation panels, and IT/OT cybersecurity via the Capula brand) — across ten vertical sectors including healthcare, education, government, heritage, commercial, life sciences, industry, energy & utilities, nuclear, and transport infrastructure. Named customers span NHS trusts, Tate Art Galleries, National Grid, EDF's seven AGR nuclear power stations, and Manchester Science Park.

Dalkia UK monetises through long-term enterprise contracts and managed services priced on a quote, project, or framework basis (e.g., the GLA RE:FIT 5 framework). The company employs 5,200+ staff in the UK following the July 2025 commencement of the Nuclear Power Stations FM contract, and operates from a London head office at Angel Court plus a Manchester registered office at Old Park Lane. The CEO Gautier Jacob has set a growth strategy targeting UK activity revenue above £750m by 2026, underpinned by organic expansion, the SPIE UK acquisition (now Dalkia Operations Limited), and EDF Group capital and customer access. Recent signals include the September 2025 graduate apprenticeship scheme, ISO 9001 and 14001 certifications, RoSPA Zero Harm Recognition, and a 5.64% reduction in CO2 emissions in 2025 against restated 2024 figures.
