Charging

We regulate and oversee a number of different charges that companies set. These cover a range of policy areas, including:

  • charges schemes
  • wholesale charges
  • bulk supply charges
  • new connection charges
  • access pricing

Charges schemes

A charges scheme is a statement of each company’s charges and associated terms, such as times and methods of payment. It has to cover all charges that have not been levied in accordance with agreements with the persons to be charged, or under specific statutory powers.

Wholesale charges

Wholesale charges are charges from wholesalers to retailers.

Effective 1 September 2016 (following amendments to the Water Industry Act 1991) we have a duty to set the rules that wholesalers must use when setting their charges for wholesale services.

From 1 April 2017, companies must follow the new wholesale charging rules we have set out.

Bulk supply charges

‘Bulk supplies or discharges are a supply of water or discharge of sewerage from one appointed company to another.  There are two types:

  1. between an incumbent water company and another incumbent water company; or
  2. between an incumbent water company and a new appointee

Incumbent to incumbent bulk supplies of water are also known as water trades.  There are no charging rules for these agreements. However, to encourage water trading in our PR19 methodology we set water trading incentives for new water trades agreed in 2020-25. To qualify for the incentive, the water company would have to show that its trade complies with an Ofwat approved trading and procurement code.

Currently there are no charging rules for bulk supplies or discharges between incumbents and new appointees.  However, if water companies fail to agree on the terms of their bulk agreement, including the charges, they can ask us to make a decision (a ‘determination’) about what the terms and conditions should be. Our existing guidance can be found here:

New connection charges

The Water Industry Act 1991 (as amended by the Water Act 2014) allows us to set rules about the charges that developers and other customers pay water and sewerage companies for new connections and other infrastructure services.

From 1 April 2018, a new set of rules covering the charging for new connections and requisitions for companies wholly or mainly in England come into force. These new rules include requirements for water and sewerage companies to provide upfront charges for most connections services and make the charges for offsite reinforcement works more transparent and cost reflective.

Additionally, we are in the process of working with the Welsh Government and the Welsh water sector to develop a set of new connections rules to apply to companies that are wholly or mainly in Wales.

Access pricing

Wholesalers provide a range of other services, some of which require individual pricing approaches.

We issued a discussion paper on access pricing: Future access pricing in the water sector – a discussion paper
