Much of the cost of our water services goes to pay for collection and treatment of water to its very high standard for drinking. Our water and sewerage bills also pay for disposal of sewage, improvements to the supply network, reducing leakage, preventing sewer flooding and, not least, conserving the natural environment on which our water supply depends.

In England and Wales our drinking water costs around 1p for 10 litres (more than 17 pints). As a proportion of income, in England and Wales the cost of water and sewerage together works out at less than 1.5% of weekly earnings – around 90 pence per day.
Around the country, prices vary between one water company and another. This is because the types of supply (reservoirs, underground sources, rivers etc), the quality of raw water, and geographical and environmental factors are different for each area. Therefore water and wastewater services have to be priced according to local conditions.
- The average household bill for water and sewerage in England and Wales is projected to be £330 for 2008-09. (Ofwat)
Most household customers pay for their water services based on the rateable value of their property. However, almost a third now have meters and are charged according to the amount of water they use.
- In 2008 the number of metered customers is 33%. This is expected to rise to 35% by March 2009. (Ofwat)
Each year the economic regulator for England and Wales, Ofwat, publishes detailed information for customers on the price of water, showing how much each water and wastewater supplier charges, how prices have changed and values for the costs associated with domestic consumption.
- The average increase in prices for 2008-09 was 5.8%, which included inflation of 4.3% (Ofwat).

In England and Wales price limits are set for five-year periods by the independent economic regulator for water, Ofwat. Today’s prices were set in 2004 for the period 2005-2010.
In Scotland the Water Industry Commission for Scotland sets prices. In 2009 prices for 2010-14 will be set.
Northern Ireland prices are currently regulated by government but this will change from 2009, starting with the price review for 2010-2015, when the Utility Regulator for Northern Ireland takes over.
Prices go up only as much as the regulator thinks is absolutely necessary and water companies are expected to be very efficient in the way they operate – to deliver water services cost-effectively and to a very high standard. This is monitored and the economic regulator reports on progress annually.
- The next reviews of water prices are already under way. Prices for 2010-15 (England & Wales) and 2010-14 (Scotland) will be set in 2009.
In October 2005 an independent consumer organisation representing the interests of all customers in England and Wales, the Consumer Council for Water (CCWater), was established.
This water watchdog (which replaced WaterVoice) provides a strong national voice and regional representation for all consumers. CCWater is committed to ensuring customers get value for money, that problems are sorted out quickly and that water and wastewater services are of a high standard.
Customer representation in Scotland is through Waterwatch Scotland and in Northern Ireland, the Consumer Council.
Investment in water quality, infrastructure and resources
A proportion of the household water bill pays to support capital investment. This includes costs for essential work to maintain and improve water quality and the infrastructure and to develop resources to meet water demand in the UK that is growing year by year.
- Between 2000 and 2010 almost £17 billion will be invested in improvements in England and Wales. Some £60 billion has been invested since 1989.
Prices set by Ofwat for the current regulatory period (2005-10) include: investment to replace 22,000km of water mains to be laid, renewed or relined; a major programme of environmental improvements (for rivers and coastal waters); the connection of almost one million new properties to the network; and work to prevent and alleviate sewer flooding.
For most customers water and sewerage charges are a relatively small proportion of their income. However, the same may not be true for households on low fixed incomes.
The water industry is conscious of the impact rising bills may have on customers who can’t easily afford, or are already struggling to pay, their bills.
To help these customers, companies offer a range of measures, including: helplines, flexible payment plans, referrals to charitable trusts and hardship funds, free water meters and help in applying for direct payment from tax credits and other benefits. Water service suppliers also offer advice on special tariffs and point customers to debt advice agencies where appropriate.
Water companies are working with government departments and other agencies to address issues of non-payment among customers.
