There has absolutely been bad practice. I have had my concerns about Thames Water in the past, but today the company has capped its dividend payments, is investing more in resilience and is doing a whole new range of different activities, and my concern is that we risk cutting off an enormous amount of infrastructure investment if we do not get this right. I think there is a way forward, and I will touch on it in a moment.
Compared with 30 years ago, customers are now five times less likely to suffer from supply interruptions, eight times less likely to suffer from sewer flooding and 100 times less likely to have low water pressure. The hon. Member for Harrow West talked about Welsh Water; he is right that people sometimes suggest that it is a mutualised organisation, when it is a private company. Welsh Water loses 121 litres per property in leakage, which is more than nearly every other water company. Its average combined water and sewage bill is £439, which is 8% higher than the average English and Welsh bill, at £405. It is higher than the bill in six English companies, and that is in a country where there is no shortage of water. I come from the Thames Water region and we are short of water there, but in Wales they are not so I cannot understand why the bills are so high. In Welsh Water, the average number of minutes lost due to supply interruptions is 43 minutes, which is about 400% higher than in most other companies, where fewer than 10 minutes are lost.
The picture is not universally wonderful, and there occasionally needs to be a bit of balance in the subject. Water companies have reduced leakage by a third since the 1990s. We are about to see an incredible increase in innovative methods of detecting leakage, and it is right that in the current price review round there is an enormous driver on those companies to crack down on it further.
On the environment, standards have dramatically risen, with the welcome return of wildlife to rivers that had been biologically dead since the industrial revolution. Otters rely on healthy rivers and were thought to be on the verge of being wiped out 30 years ago, yet they are now seen in every county in England.
The average domestic water bill is just over £1 a day—that is £1 a day to get all the water we need into the household, and all the sewage and waste water out. Although bills went up immediately after privatisation to help deal with decades of under-investment when the industry was owned and run by the Government, bills
have stayed pretty much the same in real terms since 1994 after inflation, and are set to fall in real terms over the next few years. By 2025, bills will have fallen in real terms for a decade. The industry’s independent regulator Ofwat—which has just come in for some stick—has calculated that bills are £120 lower than they would have been if the combination of privatisation and tough independent regulation had not happened. Bills would have been £120 more per household if the industry had remained in public ownership.
On the subject of customer satisfaction, the hon. Member for Harrow West has said that people are terribly dissatisfied with their water companies. I went on the internet last night to look at what Ofwat, the Consumer Council for Water and individual water companies are saying, and customer satisfaction levels for water and sewerage services are around 90%. As politicians, would we not love to have a bit of that, particularly at the moment?
