We are a statutory body and our powers are set out in legislation. The Water Industry Act 1991 (WIA91) is the main source of our powers to determine disputes. We also have concurrent powers with the Competition and Markets Authority (CMA):
- under the Competition Act 1998 (CA98) to deal with competition concerns that arise within the water and sewerage sectors
- under the WIA91 and the Enterprise Act 2002 to initiate a market investigation in relation to commercial activities within the water and sewerage sectors if we consider those activities may prevent, restrict or distort competition
Complaints under the CA98
We have the power to investigate matters where anti-competitive behaviour has been alleged within the water and sewerage sectors. Any competition related concerns you have can be raised either directly with Ofwat or with the CMA with whom we share these competition powers. If you refer your case to the CMA, they will coordinate with us as to who is best placed to lead on the issue.
Complaints under the WIA91
Customers that are dissatisfied with their water or sewerage company should contact their water company in the first instance to see if the issue can be resolved directly with the water company. We will not normally consider complaints under the WIA91 where the water company has not had an opportunity to look into the matter and put things right.
In the event that the matter is still not resolved, the Consumer Council for Water (CCWater) may be able to help solve the issue. Except for non-household related complaints, we expect customers to have referred their matter to CCWater prior to any complaints which CCWater could not resolve being considered by us.
The most common disputes we deal with include the following.
Guaranteed standards scheme
- A dispute over a customer’s right to a payment or credit if a company does not meet required standards as set out in the Guaranteed Standards Scheme (GSS) (sections 38 & 95 WIA91 and the GSS Regulations).

- Disputes about water companies’ work in private land (section 159 WIA91).
Complaints we cannot deal with
As Ofwat’s powers are set out in legislation, there are, inevitably, a number of areas in which Ofwat does not have a role. Some of the things we do not deal with are the following.
- Non-regulated activities of water companies. We do not regulate these activities, which include:
- plumbing services (typically dealt with by water companies, who are responsible for the enforcement of the Regulations within their water supply areas)
- insurance for water supply pipes (typically dealt with by the Financial Conduct Authority and the Prudential Regulation Authority)
- waste management (typically dealt with by the Environment Agency)
- vehicle leasing (typically dealt with by the British Vehicle Rental and Leasing Association, BVRLA)
- fish farming (typically dealt with by the Centre for Environment, Fisheries & Aquaculture Science (CEFAS) and the Environment Agency)
- Issues which can only be dealt with through the courts. These include disputes concerning private water supplies; contractual claims; and damages claims arising out of, for example, negligence.
- Billing disputes (typically dealt with by CCWater).
- Water quality and pollution (typically dealt with by the Drinking Water Inspectorate (DWI and EA)).
