Do you have Loft + Cavity Wall + Below Wood Floor Insulation?

If the answer is "no" to all 3 then you could save £400/yr on your
electricity bill.

The op already confirmed they have roof/cavity insulation and DG.

Possibly not underfloor insulation, but for most situations that's
marginal in benefit, and is disruptive to install
