The UK wants to encourage more homebuyers to go green. Starting from next week, Barclays will be offering lower interest rates for homebuyers who purchase new build homes that meet their energy efficiency rating qualifications and are built by one of the five pre-selected companies. Not only is the discount enticing, but Barclays is also claiming that these properties will also repeatedly save customers money through being energy efficient. By next year Barclays hopes to expand their market to a wider range of consumers and types of properties.
