Water and sewerage services in England and Wales are not provided in competitive markets. Most people receive their water services from a licensed monopoly company. Only very large business customers are able to choose their supplier.
Because competition is limited, there is a risk that these companies will not deliver the services their customers want. They may also charge higher prices to increase their profits. This is why they need to be regulated. And it is why Ofwat was created when the water and sewerage sectors were privatised in 1989.
One of the ways we regulate is to set the price, investment and service package that customers receive. This includes setting limits on the prices the companies can charge their customers. When we do this we must balance the interests of consumers with the need to make sure the sectors can finance the delivery of water and sewerage services. We also need to make sure they are able to meet their other legal obligations, including their environmental and social duties.
We currently carry out a review of these price limits every five years.
