Like me, my hon. Friend has a rural constituency, and many of us live off-grid and are at the mercy of these rises. We know that the market for heating oil does function: it has been reviewed and is considered to be competitive. But my hon. Friend will know that I have also set out an aim that we want to get all new properties built in areas off-grid off fossil-fuel forms of heating by 2025, as that is not only costly but very carbon-producing.
