Guidance
Heat Networks Delivery Unit
Support and guidance for local authorities developing heat networks.
Overview
Local authorities have a key role to play in making heat networks succeed. Their involvement, particularly in the development stages, can help realise the benefits of heat networks, while also delivering jobs and growth. In order to address the capacity and capability challenges which local authorities identified as barriers to heat network deployment in the UK, the government set up the Heat Networks Delivery Unit (HNDU) in 2013.
The Heat Networks Delivery Unit provides grant funding and guidance to local authorities in England and Wales for heat network project development.
Since its inception, the HNDU has run six funding rounds – awarding £14 million in total – and is currently running Round 7. Over 200 unique projects have so far been supported across 139 local authorities.
See the overview of government support for heat networks.
Scope
The Heat Networks Delivery Unit provides support to local authorities in England and Wales through the early stages of heat network development:
- heat mapping
- energy masterplanning
- techno-economic feasibility
- detailed project development
- early commercialisation.
See the table below for details about each stage.
HNDU support does not provide funding for late commercialisation costs and costs associated with the construction, operation and maintenance of a heat network. The Heat Networks Investment Project (HNIP) is a £320m capital investment programme providing support for the capital costs of heat networks.
The process
Local authorities apply for HNDU support through bidding rounds. All bids are reviewed by HNDU assessors before final recommendations are approved by a panel of financial, commercial and policy specialists.
Grant funding is provided to successful local authorities under Section 31 of the Local Government Act. Eligible costs are defined as externally commissioned consultancy costs for heat network development work. HNDU funding comprises no more than 67% of eligible costs.
If successful, each local authority is supported by a team of specialists within HNDU.
Round 7
Round 7 is open for applications.
Round 7 is an open funding round, running from 5 January 2017 to 31 January 2018. For details on how to apply, please see HNDU Round 7: Overview:
