This new home energy system works while you sleep - and can shave nearly £1000 off UK electricity bills, with no upfront costs

Government research shows energy bills remain one of the biggest concerns for UK households, especially at this time of year as temperatures drop.

Price volatility and uncertainty around future costs continue to weigh heavily on millions of people, but a new UK-developed home battery subscription service is aiming to cut household electricity bills by close to half.

Wondrwall is looking to disrupt the market by shifting when energy is bought, rather than how much is used. The system is designed around a simple but effective idea: draw in electricity overnight when prices are at their lowest, and then use that stored power during the day when grid prices spike.
