In the UK, communal heat networks supply heat and hot water to many households. While there was minimal oversight for small landlords running such a system earlier, from January 27, 2026, things have changed as Ofgem has stepped in as the regulatory enforcer.<\/em><\/p>\n

Communal heating systems, generally powered by a gas boiler, are a common feature in most residential developments in the UK. They are also used by many private landlords<\/a> with multiple rental units to supply heat to each household. While heat networks were previously subject to limited rules such as metering and billing requirements, they were not regulated in the same way as electricity and gas suppliers.<\/p>\n

However, from January 27, 2026, even small landlords<\/a> operating communal heating systems serving more than one property must register their heat networks with Ofgem<\/a> under the UK Heat Networks Regulations 2026. While registration becomes mandatory before the January 2027 deadline, there are many other regulations that landlords, property managers, and rental portfolio owners<\/a> must take note of.<\/p>\n

What are heat networks?<\/h2>\n

Heat networks are systems that distribute heat from a centralised source, like a boiler or heat pump, to multiple apartments or households in the UK. Depending on the size and scope of the heat system and the number of units it supplies, these networks are categorised as district or communal heat networks. <\/p>\n

Most landlords use a communal heat network to supply heat to units within a residential block. With the new regulations taking effect, they will be considered a heat network operator or supplier and must follow the heat network rules for UK landlords.<\/p>\n

Ofgem\u2019s new regulatory role<\/h2>\n

The Office of Gas and Electricity Markets (Ofgem) is the national regulatory body for electricity and downstream natural gas markets in Great Britain. While electricity and gas suppliers have long been regulated by Ofgem, the new framework now extends similar oversight to heat networks. <\/p>\n

Under the new Ofgem guidelines<\/a>, all existing heat networks are automatically \u201cdeemed authorised\u201d until the official registration deadline of 27 January 2027, before which landlords need to formally register their networks.<\/p>\n

Who must register with Ofgem?<\/h2>\n

The new guidelines apply to anyone operating a system that supplies heat to more than one property. This includes:<\/p>\n
