WITH snow continuing to rain down on the UK, families are looking for easy and cost-effective ways to keep their homes warm.
Lidl has released a £6.99 thermal window foil they claim could save the average family over £100 on their heating bills – but is it any good?
The device, which will be available in stores from 19 January 2017, works by providing an additional layer through which heat has to escape.
Lidl claims that heat-saving foil means that single-glazed windows are taken to the resistance levels of double-glazed, and double to triple glazed.
It also says that the annual average energy bill will be cut by 13 per cent – if they install the foil on all the windows in their home.
This is based on the house having eight windows and spending an average of £1,000 on gas and electricity per year.
