Albion Water customers will receive a 5 per cent discount on sewerage services compared with the volumetric charges of Thames Water, while it will match fixed and volumetric potable water charges and fixed sewerage services charges.
Ofwat said it was satisfied that Albion Water will offer customers on the site “at least equivalent levels of service to Thames Water”.
The changes will see Albion Water supply water and sewerage services to 368 new household properties and sewerage services only to 370 existing household properties.
Albion will be providing potable water, non-potable ‘green’ water, sewerage and sewage treatment across the development as well as a range of ancillary environmental services.
The mechanism, known as “varying the appointment”, allows Ofwat to replace a company as the appointed water and/or sewerage company for a specified area.
To qualify for seeking a new appointment or variation, customers in the area must use at least 50 million litres of water a year in England or 250 million litres in Wales at each of its premises.
