What Integral UK does

Integral UK Limited is a UK provider of mechanical, electrical and fabric property maintenance services, operating as a wholly-owned subsidiary of JLL (Jones Lang LaSalle) since 2016. The company's heritage traces to 1863 as Staveley Industries PLC; it was rebranded as Integral in 1997 following a management buyout in 2005. With approximately 4,000 employees including over 1,000 directly employed mobile engineers, Integral describes itself as the UK's largest self-delivery building maintenance engineering provider. It operates from six regional offices (London, Chatham, Leicester, Newcastle, Warrington) plus a 24/7 national call centre, serving enterprise clients across retail, food production and cold-chain distribution, life sciences, data centres, finance, manufacturing, and public institutions.

Core offerings span industrial refrigeration (ammonia, CO2, glycol and low-GWP HFC/HFO systems), HVAC solutions (chillers, heat pumps, air conditioning, close-control systems), retail and commercial refrigeration (including the LOKOLD refrigerated display cabinet sub-brand), small works and projects, and consultancy/advisory services. Under the Integral Cooling Tech division, the business has expanded into Critical Environment Cooling for data centres, cleanrooms and healthcare. The technology stack combines in-house 3D BIM and AutoCAD design with the AM360 asset management platform and an IoT/AI smart-building layer built on partnerships with Disruptive Technologies (sensors) and Infogrid (AI analytics), enabling automated Legionella compliance, leak detection, humidity monitoring and door-activity analytics.

Integral generates revenue primarily through long-term managed service contracts, recurring planned-preventative and reactive maintenance agreements, and project-based professional services for new installations and upgrades. GTM is enterprise field sales with direct B2B contracting and nationwide mobile engineering delivery. Pricing is not publicly disclosed and is negotiated per contract. The customer base is concentrated in large enterprise accounts (Lidl, Harrods, Rolls-Royce, Pukka Pies, Samworth Brothers, Royal Opera House, Sir Robert McAlpine, and an NHS Foundation Trust), supported by an extensive certification stack covering ISO 9001/14001/45001, NICEIC, Gas Safe, Fgas, CHAS, Constructionline Gold, BAFE, BSI Kitemark, Cyber Essentials and Cold Chain Federation membership.
