Heat Pump Ready Programme Stream 2 Wave 2 competition

The Department for Energy Security and Net Zero (DESNZ) Heat Pump Ready (HPR) Programme Stream 2 Wave 2 competition will support applied research and development projects, focused on driving down the lifetime costs of domestic heat pump deployment, and improving the domestic consumer experience and acceptability of heat pumps through technology, tools, business model, and process innovation.

It aims to develop solutions that:

  • improve the ease of heat pump deployment in homes that are ‘complex to decarbonise’ by addressing physical, material, locational, technological, regulatory, or social challenges;
  • develop innovative solutions to enable heat pumps to be deployed in ‘distress purchase’ situations when a new home heating system is required urgently;
  • improve performance and/or reduce costs of domestic heat pumps with low global warming potential (GWP) refrigerants (below 150 GWP), while ensuring safety; and
  • reduce the lifetime costs or improve the overall lifetime performance of domestic heat pumps or improve the domestic consumer experience of using and living with a heat pump.

The HPR Programme is funding the development of technology and tools which are expected to be nearing commercialisation by the end of their projects. The solutions supported in Stream 2 Wave 2 must be:

  • hardware at Technology Readiness Level (TRL) 5/6/7 at the start of a funded project, with the expectation that technology developed through the competition projects will reach TRL 7/8/9 by the end of the project; and
  • software at Discovery/Alpha phases at the start of the project but should not be at Beta or Live phase – software is expected to reach Live phase by project completion.

Up to £10 million of grant funding is available in total through the competition. The maximum possible grant funding for a single project is £1.5 million and successful project teams will be required to provide private sector funding alongside the grant funding provided from the HPR Programme.

Applications are open until Monday 8 January 2024.
