Existing evidence suggests that the early adopters of microgeneration systems are higher income groups [22]. If policies designed to encourage DG are focused on households installing and paying for small-scale generation technologies (as is the case for the current FIT scheme, and the Low Carbon Buildings Programme),21 Walker [89] argues that there is the risk of middle classes actively investing in such technologies, whilst the low-income groups rely on traditional electricity and gas supplies. If technology advances mean that investors in microgeneration benefit from falling energy costs, then the problem of fuel poverty will be exacerbated. Walker [89] instead argues that national and local governments, housing associations and/or energy providers should actively pursue the provision of microgeneration technologies in alternative ways, for example via fuel poverty programmes that provide grant funding for low-income groups
