An expert has said that good wall insulation and energy efficient boilers, or anything that contributes to low carbon emissions, will assist in a home's value. Julian Brooks, managing director of GreenMoves, said: "Awareness is an issue but will slowly come, as the CO2 issue is gaining a great deal of momentum, aided and abetted by the cost of fuel. Green homes cost less to run, of course, so they make good economic sense."Green homes are a good investment without a doubt and will pay dividends over time as they are likely to hold their value more."A report earlier this year by the Communities and Local Government committee found that the average existing home in the UK emitted 1.6 tonnes of carbon a year, where as newly build energy efficient houses emitted only 0.86 tonnes.
