Get a grant to green your home

Energy companies are sitting on unclaimed grants and benefits arising from the Carbon Emissions Reduction Target (Cert), which was launched in April last year. Under Cert, energy firms must offer grants to enable householders to make their homes more energy efficient, says The Guardian. Many of these are open to anyone and can be taken up even if the firm offering the deal isn't your energy provider.
