Ten million of the UK’s 28 million homes could need some form of retrofitting if the country is to shift to low-carbon heating, the Energy Technologies Institute (ETI) has calculated.

The ETI’s new The Journey to Smarter Heat report said work must start “almost immediately” due to the scale and complexity of the transition.

It highlighted that providing domestic, industrial and commercial heat is the UK’s largest emitter of greenhouse gases.

The report brings to an end the first phase of the ETI’s Smart System & Heat programme, run in conjunction with the Energy Systems Catapult (ESC).

Demonstration projects

Andrew Haslett, Chief Engineer at the ETI, said: “The next decade will be critical in preparing for any low carbon heating transition, with rapid implementation required from 2025 to build supply chain capability and capacity.

“It is important that solutions that work at the scale of large towns and small cities are demonstrated if we are to roll them out across the UK in time."

“This real-world demonstration phase has already been progressed by the ESC, which – building on the learnings from phase one – established a “living lab” of circa 100 homes.”
