DALKIA FACILITIES LIMITED

What DALKIA FACILITIES LIMITED does

Dalkia Facilities Limited (trading as Dalkia UK) is a wholly-owned UK subsidiary of EDF Group, one of the world's largest energy companies. The company provides integrated technical and energy services to enterprise and public-sector clients across the United Kingdom, with 5,200 staff and headquarters at Angel Court in the City of London. Its offering is organised around four service lines: Engineering Services (mechanical, electrical, public health, HVAC, HV/LV installations, specialist cleanroom, tunnel, and fire and security work), Facilities Management (planned and reactive maintenance, integrated building services, energy management, and customer service centre operations under multi-year contracts), Energy Services (decarbonisation projects, district heating network design and operation, heat pumps, solar PV, EV charging, and green hydrogen facilities, often delivered through Energy-as-Service and Energy Performance Contract structures), and Advanced Systems Integration delivered through its Capula subsidiary (automation, control systems, instrumentation panel design and build, and IT/OT cybersecurity for highly regulated industrial environments). Dalkia Cleanrooms operates as a specialist sub-brand serving pharmaceutical, life sciences, micro-electronics, and healthcare clients.

The company serves ten primary verticals — Healthcare, Education, Government, Nuclear, Energy & Utilities, Heritage/Leisure/Museum, Life Sciences & Pharmaceutical, Industry/Manufacturing & Technology, Tunnels/Transport/Infrastructure, and Commercial & Corporate. Distribution is exclusively direct-to-enterprise: business development and account management teams pursue major projects and framework agreements, complemented by public-sector procurement frameworks (notably the Greater London Authority's RE:FIT 5) and direct industrial relationships via Capula. Named anchor customers include EDF (Hinkley Point C, Sizewell B), National Grid, the UK Parliamentary Estate, Northumbria Healthcare NHS Foundation Trust, the University of Dundee, Tate Art Galleries, and Manchester Science Park (Greenheys). Revenue is generated through fixed-price project contracts, multi-year managed services, and guaranteed-outcome energy performance contracts; pricing is not publicly disclosed and varies by project.

The business is positioned around the UK's net-zero transition, holding Tier 1 Contractor status on Hinkley Point C and committing to Net Zero Scope 1 and 2 by 2030 with fleet electrification in progress. Operations span England and Scotland, with a formal Dalkia Scotland division. Competitive positioning is anchored by EDF's capital and technical backing, deep credentials in regulated sectors (nuclear, NHS live environments, heritage buildings), and an in-house multidisciplinary workforce spanning engineering, FM, energy services, and OT cybersecurity — a combination that supports long contract durations but also ties growth to UK infrastructure, nuclear new-build, and public-sector decarbonisation cycles.
