Powerstar, a new system from EMSc, is helping a number of councils across the UK to decrease their energy costs.

The firm has fitted its voltage optimisation appliance at North East Lincolnshire Council, which has duly enjoyed energy consumption savings of 24.72 per cent, as well as saving £6,094 on its annual electricity bill.

Dr Alex Mardapittas, EMSc managing director and designer of Powerstar, said: "We employ two dedicated Powerstar public sector consultants with comprehensive and specialist knowledge of voltage optimisation in local authorities, central government and the NHS."

Mr Mardapittas explained that the consultants are uniquely trained to handle the challenges brought about by the public sector when it comes to making savings.

While such technology will help to lower costs, Ann Robinson, director of consumer policy at uSwitch.com, has argued that residents have the power to force change with regard to their heating bills.

Ms Robinson advised people to shop around in order to find the best deal for their needs.
