What CorEnergy does

Sureserve Group Limited (formerly CorEnergy) is a privately held UK company that delivers energy efficiency, decarbonisation, and safety compliance services to the social housing sector. The company is structured around two operating divisions: Sureserve Energy Services, which provides design and retrofit planning, solar PV, insulation, BESS battery storage, air source heat pumps, ventilation, decarbonisation consultancy, and grant funding assistance; and Sureserve Compliance Services, which delivers heating, water, electrical, and fire safety compliance solutions. A nonprofit-affiliated entity, the Sureserve Foundation, supports community initiatives.

The company serves housing associations, local authorities, and social housing residents across the United Kingdom, with documented case studies in Shoreham, Lincoln, South Wales, and the West Midlands. It holds six major industry certifications (MCS, Gas Safe, Achilles, TrustMark, IAA, HETAS) and operates as a certified Honeywell Gent fire safety partner following its April 2026 approval. The London-headquartered firm (Norfolk House, 13 Southampton Place, WC1A 2AJ) generates revenue through professional services contracts with public sector clients, with pricing not publicly disclosed and engagement driven by direct enterprise field sales.

The business model is anchored to UK government social housing and decarbonisation policy, including alignment with the Warm Homes Plan, ESG reporting mandates (the company published its first ESG Impact Report in April 2026), and net-zero targets. Go-to-market is relationship-based enterprise sales targeting housing association and local authority procurement frameworks, supported by case study marketing, industry conference participation (Housing 2026), and a multilingual Resident Hub for social housing tenants.
