By 2027, heat networks must comply with HNTAS standards under Ofgem regulation. Operators must register, submit performance data and meet KPIs on reliability, billing transparency and heat loss. Failure to comply risks fines up to 10% of turnover or £1m. Key deadlines begin in 2026.
The Carrot HNES Funding HNES provides 100% grant funding for optimisation studies (£15k–£45k per site) and up to 50% funding for capital upgrades such as Heating plant and system improvements. New funding rounds are expected in March– May and August–October 2026.
