Britons are increasingly looking towards the running costs of a home when deciding whether to upgrade their property, it has been said.The energy efficiency of a kitchen could be one area which people consider when scouring the market for a new home.Such green credentials mean that many buyers are looking into new build homes as one way of cutting their energy bills, David Bexon, managing director of SmartNewHomes.com, claimed.However, homeowners looking to sell up may want to give their kitchen a revamp in order to make it more attractive to would-be buyers.Mr Bexon said Homebuyers are now more concerned about the impact of their home on the environment and perhaps more significantly these days, how this equates to solid cash savings.One way to cut energy bills and make a home more efficient could be through updating kitchen taps.Writing for the Telegraph, Kara Gammell said her leaking hot water tap could have pushed her water and gas bills up by 30 a year.Fitting kitchen tap aerators was one way she attempted to make her kitchen cheaper to run.
