Most new-build properties have an EPC rating of C or B, but few homes reach A status. James Alcock, at TheGreenAge, which offers energy efficiency home assessments, says: ‘It is relatively easy to boost your home from G to E or E to D with better heating and insulation. But it gets harder and more expensive to boost your rating once you reach C.
To get a rating of B or A you need to start producing your own electricity or hot water using solar PV, solar thermal or air-source heat pumps.’
