Yes. The article mentions that type too but cites a drawback in the way some have been implemented.

Under the Stithians model, Kensa Utilities will own the infrastructure under the street until it enters the property, after which the in-home pipework and heat pump will be owned by the homeowner — this, crucially, allows residents to choose their own heat pump and their own electricity supplier to run the pump.

Kensa says more than half a million households currently connected to traditional district heating systems, which pipe waste hot water from council incinerators, for example, can be at the mercy of unrestricted prices because they can’t switch suppliers. This has led to reports of communal boilers being switched off to save costs — or boilers being left on when they are not needed.
