Heat Network Compliance Support for 2027

From January 2027, Ofgem becomes the regulator for heat networks across England, Scotland and Wales — the first time in UK history that heat networks have had economic regulation comparable to gas and electricity. The regulation applies to communal heat networks (a single block of flats with shared plant) and district heat networks (multiple buildings on a shared network). Most blocks built in London since 2010 have a heat network and a Heat Interface Unit in every flat.

Heat suppliers — typically the freeholder, the resident management company, or an appointed managing agent — will need to demonstrate, at audit, that:

• HIUs are serviced and maintained on a documented schedule
• Repairs and engineer attendance are recorded with audit-grade detail
• Engineers are trained on the specific HIU brands installed in the network
• Billing is grounded in accurate metering and proper unit performance
• Residents have transparent pricing and clear redress if service falls short

We supply the engineer-side records that feed into compliance: planned servicing programmes for portfolios of any size, digital service certificates after every visit, manufacturer-approved engineer training records, and a single accountable point of contact for the duration of the contract. We frequently take over from incumbent contractors and audit existing maintenance history for gaps before the regulation deadline. We don’t operate as the heat supplier ourselves — that role stays with the freeholder, RMC or managing agent — but we are the engineering arm those parties rely on to be ready for 2027.
