Money Saving Boiler Challenge: Supporting evidence October 2022

This report summarises the evidence underpinning Nesta’s Money Saving Boiler Challenge campaign.

In 2022, Nesta launched a campaign to help households save money by lowering the flow temperature on their condensing combi boilers to 60°C. This report summarises the evidence underpinning Nesta’s Money Saving Boiler Challenge campaign.

Our evidence suggests that households could save about 9% on their total gas bill by doing this, assuming their flow temperature is currently set at 80°C.

We’ve based our stated 9% gas bill saving, and the advice to lower to 60°C, on multiple sources of evidence. Findings from real-world experiments and modelling both point toward a similar gas saving and similar impacts on room temperature.

Nesta is confident this advice will have a positive impact on households with combi boilers across the UK by helping them reduce their gas consumption and bills. It will also contribute towards lowering the UK’s household carbon emissions.

Money Saving Boiler Challenge

Our campaign aims to help over one million households change their combi boiler settings to save energy.
