About the Strategic Innovation Fund (SIF)




An Introduction

The Strategic Innovation Fund (SIF) is designed to drive the innovation needed to transform gas and electricity networks for a low-carbon future.


  • to find and fund ambitious, innovative projects which can help shape the future of the energy networks and accelerate the transition to net zero, at lowest cost to consumers
  • to help transform the UK into the ‘Silicon Valley’ of energy, making it the best place to be a) an energy consumer and b) an energy entrepreneur.

Delivered in partnership with Innovate UK, the SIF programme taps into the best of UK and international innovation whilst aligning with other public innovation funding for the benefit of network users and consumers.

It was launched in 2021 and is expected to invest £450 million by 2026, with the option to increase and extend as necessary.

Part of the RIIO 2 price controls, the SIF is a funding mechanism for the Electricity System Operator, electricity transmission, gas transmission and gas distribution companies, working in partnerships with other innovators. From 2023 the distribution network companies can also take part.
