Smart meters can be a "great start" in helping consumers lower their energy bills, says David Weatherall, housing strategy manager for the Energy Saving Trust.

"The first step to cutting your energy use is to know when and how you're using it," he explained.

Smart meters provide real-time displays of the energy being used in the home, allowing people to monitor their energy use.

In today's consultation response the government has announced details of a mass roll-out of the devices from 2014. The role out is anticipated to save a total of £7.3 billion in fuel bills over 20 years.

Mr Weatherall noted, however, that smart meters will not physically make a home more energy efficient; it is up to households to change their behaviour.

"The householder has to be engaged enough to take action based on the information they're given," he said.

"A national roll-out of meters is no easy undertaking, but providing homeowners are clear of the benefits and how to get the best out of them, it could potentially bring [about] big changes in our relationship to energy."

 
 
The government has revealed its plans for a mass smart meter rollout to every home in the UK.

It will start to deploy 53 million smart meters to 30 million homes and businesses from 2014, with a scheduled completion date by 2019.

Smart meters can help households monitor their energy use and allow them to reduce the carbon emissions of their home. In addition, data from the devices can be read remotely by providers and lead to accurate energy bills with no estimated readings.

With real time information on their energy consumption, homeowners can save around £23 a year on their energy bills and the technology will help the move to smart grids which will support renewable energy supply, the government said.

"Smart meters are a key part of giving us all more control over how we use energy at home and at work, helping us to cut out waste and save money," commented energy secretary Chris Huhne.

"The rollout of smart meters will help us keep the lights on while reducing emissions and getting the best possible deal for the consumer," he added.
