City Technical Services

What City Technical Services does

City Technical Services (UK) Ltd. is a Glasgow-headquartered heating, gas, and electrical services contractor operating exclusively in the Central Belt of Scotland. Founded in 2001 as a subsidiary of the City Holdings Group, the company installs more than 3,000 boilers per year and employs over 260 staff, of which 140+ are directly employed Gas Safe registered engineers with no contracted labour. Its service portfolio spans boiler installation and replacement (combi, system, conventional, and back boilers), electrical heating, system cleansing, and an expanding eco and renewables range including air source heat pumps, solar PV, battery storage, and internal wall insulation. It also administers the LEAP Boiler Scheme (via AgilityEco) and ECO Boiler Scheme for fuel-poor and vulnerable households.

The company's commercial model rests on four revenue streams: one-time installation revenue (per-job), recurring service and maintenance contracts (predominantly with social housing), emergency breakdown and repair services routed through a 24/7/365 call centre, and credit broking commission (as an FCA-authorised credit broker, FRN912336, arranging finance from a panel of lenders). Customer acquisition is sales-led, combining a 24/7 inbound call centre, a website quote tool with local SEO across 20+ Scottish towns, and channel partnerships with 30+ housing associations, local councils, and government scheme administrators. The business holds a broad compliance stack — Gas Safe, NICEIC, OFTEC, MCS, TrustMark, Constructionline Gold, ISO 9001/14001/45001, RECC/CTSI, and ICO registration — which is a prerequisite for both social housing tendering and government energy scheme participation.
