Derby sits at the centre of a Derbyshire installer market that also covers Chesterfield, Belper and the Peak District, so city homeowners can usually line up several MCS-certified quotes. The £7,500 Boiler Upgrade Scheme grant applies across England, and homes off the gas grid heated by oil or LPG — common in the surrounding countryside — now qualify for £9,000.
