We've just had cavity wall insulation installed for £200 and reinsulated the loft with 200mm insulation. The difference (subjectively till we've had time to compare figures from last year) is phenomenal. The house heats in a fraction of the time it used to, and the timer is set to not turn on a.m. because the house remains warm.

we use mostly low energy bulbs but I'm not convinced they make much difference in energy usage because the wasted energy in producing heat of the incandescent lamp is just added to the house heating. Street lamps I suppose are all low energy.

I think there's still room for reducing our consumption before we go down the road of Wind Turbines and PV panels.
