Do you recognise that, by excluding ambient loop systems with individual heat pumps that can connect to a district heat network, it is a missed opportunity to further the aims of the London Plan including promoting uptake of heat networks?

No. The London Plan heat hierarchy (policy SI 3) prioritises connection to district heat networks for developments in heat network priority areas. The decarbonisation and expansion of these networks support the capacity and resilience of the wider energy system and will play an important part of achieving our net zero target. The guidance supports the use of ambient loop systems except for one specific scenario: systems with individual heat pumps in heat network priority areas where there is potential to connect to a district heat network.
