ETI’s Smart Systems and Heat Programme
“Creating future-proof and economic local heating solutions for the UK”
Connecting together – the understanding of
consumer needs and behaviour with the development
and integration of technologies and new business
models into…
Delivering enhanced knowledge amongst industry
and public sector
Resulting in industry and investor confidence to
implement from 2020 which enables a UK heat
transition
The Energy Systems Catapult will deliver Phase
One of the SSH programme as a supplier to the
ETI following the transition of the SSH
programme team to the Catapult. From 2017 the
Catapult will be responsible for delivery of Phase
Two of the programme independently of the ETI.
