We know how investing in heat pump, CHP or other renewable technology on a commercial scale can be a significant financial outlay.

That’s why we aim to help you to find support for your project. Whether it is funding from the government or other sources, or financing options, we can guide you through the process.

Funding that is available changes regularly but some current funding options that could be available to your business are:

The Industrial Energy Transformation Fund (IETF)

We are currently in Phase 2 competition round in 2022. The Phase 2: Autumn 2022 competition closes on 17 February 2023. This is the last currently planned application window.

The IETF provides grant funding for feasibility and engineering studies, and for the deployment of industrial energy efficiency and deep decarbonisation projects covering the following project types:


Feasibility and engineering studies to enable companies to investigate identified energy efficiency and decarbonisation projects prior to making an investment decision.

Energy Efficiency

Deployment of technologies to reduce industrial energy consumption.

Deep Decarbonisation

Deployment of technologies to achieve industrial emissions savings.

  • The fund is designed to help businesses with high energy use to cut their energy bills and carbon emissions through investing in energy efficiency and low carbon technologies. The government announced £315 million of funding in the 2018 Budget, available up until 2027.
  • BEIS manages the IETF for England, Wales and Northern Ireland, with £289 million to invest over consecutive application windows split into 2 phases.
  • Phase 2 expands the IETF scope to additionally support the deployment of decarbonisation technologies. It will provide around £220 million in funding between Autumn 2021 and 2025.
  • Phase 2 of the IETF provides grant funding for feasibility and engineering studies, and for the deployment of industrial energy efficiency and deep decarbonisation projects.
  • The current round of funding is open to eligible SIC codes including industrial processes: mining and quarrying (SIC 05101 to 05200,07100 to 08990 and 09900), manufacturing (SIC 10000 to 33200), recovery and recycling of materials (SIC 38320) and data centres (SIC 63110).
  • Companies are invited to bid into any one or more strands: Studies, Energy Efficiency and Deep Decarbonisation. If the site is based in Scotland, you can apply for the SIETF.

Heat Networks Investment Projects (HNIPs)

This is a government funding programme that aims to:

  • increase the number of heat networks being built
  • deliver carbon savings
  • help create the conditions necessary for a sustainable heat network market to develop

HNIP will provide £320 million of capital funding to gap fund heat network projects in England and Wales.
