Investing in energy efficiency measures across the domestic, industrial and service sectors saved the UK £1.7 billion between 2010 and 2015, according to new figures.

An audit led by the Association for Decentralised Energy (ADE) found that the UK’s energy bill reached £140bn in 2015, the equivalent of 7.6% of the economy.

But the efficiency of electricity supply has remained broadly unchanged, improving by only two percentage points in the past five years.

The UK lags behind, France, Germany and the Netherlands when it comes to energy efficiency policies, according to the audit’s authors.

‘Policy gap’

Current renewable energy and energy efficiency policies are only able to take the UK around half way towards meeting its 2030 carbon budget, leaving a significant “policy gap”, the auditors said.

The coalition of groups that compiled the audit called on the Department for Business, Energy & Industry Strategy to address the “policy gap” and prioritise helping businesses to make additional energy productivity investments and improvements as part of the UK Government’s forthcoming industrial strategy.

As well as the ADE, other contributors to the audit included the Association for the Conservation of Energy, the Chartered Institution of Building Services Engineers and the Institution of Mechanical Engineers.
