My hon. Friend is right. I see this in household terms: my simple view is that if a builder wants to build 1,000 houses in the Test valley—I do not
know why I am picking on the Test valley; I could pick on any number of catchments in the south or east of England—for that to be considered sustainable development, he should have to prove to his local authority that he is hardwiring into his thinking recycling rain water, greywater systems and permeable membranes outside the houses. In fact, he should think of everything to ensure that the development’s water demands are as low as possible.
An important change is being made that will assist investment in our water sector, by cracking the problem with the investment cycle that we have faced for years. I am grateful to British Water—the organisation that represents supply chain companies—for drawing my attention to how investment fell off a cliff edge a year or so before the end of a price review period. That is a problem. Britain is losing jobs, losing skills to abroad and losing much-needed infrastructure investment. Three changes will make a difference in that regard. The first is the resilience duty, which I have already mentioned. The second is the requirement on water companies to invest for the long term, particularly through the 20-year reviews of their water needs. The third is the need for a six-year investment programme, which is a major step forward. Over time, the cycle of investment will level out rather than fall off that cliff.
We need to think beyond the Bill on sustainability. I am pleased, for example, that improvements to the building regulations include a standard daily usage of 125 litres per head. The code for sustainable homes refers to 105 litres per head. We use 155 litres per head in this country—a figure higher than almost anywhere in Europe. We must consider the demand side as well as the supply side.
I hope that that clause on flood insurance goes through with the support of all parties. All Members with constituents who live at risk of floods feel strongly that the statement of principles, worthy though it might have been when it was drawn up, was full of faults. There was no affordability element. Our constituents face excess charges that are at times more than £10,000—an impossible situation that cannot be allowed to continue.
I have the scars of the negotiations on Flood Re on my back—I pay full tribute to the ABI for the constructive way in which it negotiated—but I think we have reached a point at which we can address the needs of the 500,000 households that are at the highest risk. It will limit the cost, and as best it can, it will link that limit to people’s ability to pay. Linking the scheme to council tax banding is the right way to do that. Excess charges will be capped at somewhere between £250 and £500. That is a major win for those people who come to see us in our surgeries and tell us that every time it rains their stress levels rise considerably.
