Sureserve Compliance South

What Sureserve Compliance South does

Sureserve Compliance South is a regional operating subsidiary of Sureserve Group Limited, a UK social housing energy and compliance services platform headquartered at Norfolk House, London (WC1A 2AJ), with offices and field operations across England, Scotland, and Wales and, since November 2025, the Netherlands. Founded in 1988 and owned by Cap10 Partners since a July 2023 public-to-private transaction, the group delivers five compliance service lines — heating, electrical, fire, insulation, and water hygiene — plus a growing energy efficiency and decarbonisation retrofit offering (solar PV, air source heat pumps, insulation, combined heat and power, and building management systems). Its customers are housing associations (including G15-scale landlords such as Peabody and Clarion), local authorities (City of Lincoln Council, South Lakes Housing, Adur & Worthing, Havering), NHS trusts, and educational institutions (Gloucestershire College, MidKent College, York St John University).

The platform is technology-enabled but not technology-led. Core technical components include a proprietary real-time two-way ICT interface integrated into client systems for contract monitoring; a proprietary MRV (Monitoring, Reporting, Verification) solution inherited via the 2025 HI Group acquisition, which delivers half-hourly energy data, benchmarking, and optimisation; and the Thrive social value platform used for community needs analysis. The group also holds full ISO 9001 / 14001 / 45001 / 50001 accreditation, PAS 2035 retrofit certification, MCS, Trustmark, and Gas Safe status, and is the first-ever Aico Platinum Partner and a member of the Honeywell Gent Approved Network (since April 2026).

Revenue is generated primarily through professional-services contracts secured via procurement frameworks, tenders, and government programme bids. The largest disclosed revenue stream is from compliance and maintenance contracts with housing associations and local authorities (multi-year cadence, project-based pricing). A second stream is retrofit and decarbonisation project work, substantially co-funded through the UK government's Social Housing Decarbonisation Fund (SHDF Waves 1, 2.1, and 3) and the Warm Homes Plan (e.g., £3.6m SHDF award matched by £3.6m from South Lakes Housing for 905 properties). Public buildings energy services and a decarbonisation consultancy complete the mix. Sureserve Compliance South specifically delivers the southern region's compliance field services as part of this structure, supported by an in-house multi-trade workforce, dedicated resident liaison officers, and 24/7/365 reactive maintenance capability.
