Electricity and Gas (Community Energy Saving Programme) Order 2009

My Lords, I am extremely grateful to the noble Lord for his very careful explanation. Reverting to the figure of £92 by 2020, the extra burden from these measures laid on the average household: that is 10 years away. The figure of £92 is very precise. Does the noble Lord really have complete confidence in the forecasting ability of any Government, whether Labour, Liberal or Conservative, to say that in 10 or 11 years the sum is going to be exactly £92? I think that it will be in the area of £200 to £250, but that is another argument, and that is a broad-brush approach. Are the Government really wise to suggest that it will be £92, not a penny more, not a penny less?
