Gas Combined Heat & Power (CHP) continues to provides the lowest cost of heat production, protecting residents more from utility inflation than heat networks run just on gas boilers or heat pumps. CHP achieves this through the generation, and sale, of electricity, which has also increased in value.

The chart below shows how the cost of heat for 3 different technology heat networks has changed over a 3-year period.
