The savings, which apply to small and medium-sized properties, were discovered after a programme of energy-saving audits at several businesses, including a pub with a restaurant in Leeds.
The audit used the business’s average annual expenditure on energy to reveal approximate energy savings, including £3,253 from implementing voltage optimisation, £1,086 from lighting improvements and £774 from increasing staff awareness of energy consumption and implementing real-time energy monitoring.
The energy supplier found that savings could also be made from pubs implementing water conservation measures, a central heating boiler clock and a bottle fridge energy miser.
Npower has released the figures and a series of ‘infographics’ to help small businesses find simple ways to use less energy.
Phil Scholes, SME (small & medium-sized enterprises) sales and marketing director at Npower, said: “We know many owners are busy with the day-to-day operation of their pub or restaurant, so we work in partnership with them to help identify energy savings. Our audits show just how many hidden savings there are within businesses and how they can add up to significant sums of money.
“We’d encourage any pub or restaurant owners looking for help on how they can save to contact us.”
The Energy Act 2011 states that from 1 April 2018 all commercial property must have an energy performance certificate rating of at least E or face being removed from the rental market. This applies to current or new leases that will last until after 2018.
