British Telecommunications PLC holds a water supply retail licence (licence no. 079/2018/WL) and a sewerage retail licence (licence no. 078/2018/SL), both restricted to self-supply for our sites in England. Under these licences we only supply water and sewerage retail services to our own sites. Our list of supplied sites is kept updated at all times to ensure our compliance with our licence conditions. Please note that due to the sensitive nature of some of our activities, sensitive sites are not published or disclosed on our website. The regulator, Ofwat, reserves the right to carry out periodic checks on the validity of the information that is published on our website and to request information about the sites which are not published, at any point in time.
