My Lords, I thank the noble Lord, Lord Oxburgh, for laying this amendment, and I think I thank the noble Lord, Lord Cameron, for his contribution, with all his liquid metaphors. I was pleased to speak at the WaterAid reception last night, which he attended, so I assure him—I think he knows it—that we recognise the importance of water, whether it is in developing countries or in the United Kingdom.
We have thought carefully about metering in bringing this Bill through Parliament. Our position on metering seeks to strike a balance between the benefits that metering brings and the consequences that it can have for customers and their bills. We agree that metering is a fair basis for charging, but we are also concerned about the potential impacts on struggling customers. As the noble Lord, Lord Oxburgh, has observed, any customer can request a meter. The company must then
fit a meter for free. That customer has a year to decide whether to revert to paying according to the rateable value if it turns out that they are worse off.
We are already seeing increasing levels of metering across the country. Next year will see the number of metered households reach 50%, with a trajectory towards 80% by 2040. Where there is a credible economic case, any company may install meters across all or part of their area. The only restriction is on imposing metered charges on customers without their consent. Companies could, as the noble Lord, Lord Oxburgh, suggests, install a complete street or neighbourhood at the same time; and to answer my noble friend Lady Parminter, companies can put in meters throughout.
The evidence shows that the case for imposing metered charges on all customers in an area can be made in water-stressed areas where there is an insufficient supply of water to meet projected demand. The amount of available water varies around the country. When it makes social, environmental and economic sense to do so, charging all customers according to a meter is already a possibility, but in areas where water resources are not under pressure, imposing meter charges is restricted because of our concerns about affordability.
There are two sets of costs that must be considered here. First, the investment cost of installing meters across an area can put up bills for all the customers in that area. Secondly, imposing metered charges across an area can increase the bills of some of the worst off in society. This is not something that anyone wishes to do in areas that have sufficient water to meet demand.
The balance will doubtless change over time. With climate change and population growth, the case for universal metering in particular areas will no doubt shift. That is why we revised the water stress designation last year: to take better account of long-term climate projections and information about environmental pressures. We wanted to ensure that the designation of serious water stress is forward looking. It is also updated on a regular basis, and we will continue to keep the situation across the country under review. I hope that that does something to reassure noble Lords.
The noble Lord, Lord Oxburgh, asked me to clarify the circumstances in which companies can install meters, and he made the point that a number of organisations were not clear about the situation. I hope I have answered his question, but for the avoidance of doubt let me do so again for the record. Water companies are able to install meters wherever there is a good case for doing so. There is a variety of reasons why they may choose to do this, including to improve leakage detection and enhance their understanding of consumer behaviour. A number of companies already do this. What the companies are not allowed to do is to impose charges by reference to that meter without the householder’s agreement. The exception to this rule is in areas of serious water stress, for the reasons that I have mentioned. It is not the installation of meters, therefore, that is restricted; it is making people pay a metered charge without their consent in other areas. I hope that answers the noble Lord’s question.
The noble Lord also mentioned the complexity of the legislation in this area. We agree that the prescribed conditions regulations, which govern the restrictions
around metering, are complex and hard to follow. I am glad to be able to confirm that under the Government’s Red Tape Challenge, we have a commitment to consolidate these regulations by April 2015.
Water companies can install meters wherever it makes sense to do so, but it is the householder who decides whether they wish to be charged by reference to it in the areas where that is permitted. There is flexibility to allow universal metering in the wider interest of water efficiency in areas of serious water stress. This is a careful balance. I hope that the noble Lord will be willing to withdraw his amendment, although I am sure he will do so with great reluctance.
