Water company appointments (Instruments of Appointment)
Water companies operating the public water networks hold appointments as water undertakers, and those operating the public wastewater networks hold appointments as sewerage undertakers, for the purposes of the Water Industry Act 1991. They also supply water and wastewater services direct to household customers (and in some cases to non-household customers) who are connected to their networks.

Water supply and/or sewerage licences (WSSL)
Since 1 April 2017, holders of new water supply and/or sewerage licences (WSSL) can provide supplies of water and sewerage services to eligible non-household premises. Some licensees may be limited to providing water supplies or sewerage services to their own sites and those of persons associated with them (known as self-supply). There are two types of licence – water supply licences and sewerage licences, each of which can have one or more different authorisations.
Water supply licences can currently have:
- an (English) retail authorisation: this allows the licensee to supply water to non-household premises using the public water networks operated by water undertakers whose areas are wholly or mainly in England.
- a (Welsh) restricted retail authorisation: this allows the licensee to supply water to large non-household premises (consuming at least 50 megalitres of water a year) using the public water networks operated by water undertakers whose areas are wholly or mainly in Wales.
- an (English) wholesale authorisation: this currently allows the licensee to introduce water into the public water networks of water undertakers whose areas are wholly or mainly in England in order to supply the licensee’s own customers if their non-household premises consume at least 5 megalitres of water a year.
- a (Welsh) supplementary authorisation: this allows the licensee to introduce water into the public water networks of water undertakers whose areas are wholly or mainly in Wales in order to supply the licensee’s own customers if their non-household premises consume at least 50 megalitres of water a year.
Sewerage licences can currently have:
- an (English) retail authorisation: this allows the licensee to provide sewerage services to non-household premises using the public wastewater networks operated by sewerage undertakers whose areas are wholly or mainly in England.
Standard licence conditions apply to water supply and/or sewerage licences (to the extent set out in the individual licences).
Licences issued before April 1 2017 were included on an A2 Schedule. Those issued after this date have A2 directions for the Licensee’s water supply and sewerage licence. These A2 directions are listed in the table below.
