  • Developer services charging arrangements 2018-19

    Our developer charges for 2018/19 are changing significantly from the previous year in response to new rules published by our economic regulator, Ofwat.

    The changes will mean that more of our charges will be fixed and published, rather than provided on application, enabling you to estimate your costs without needing to contact us for the majority of the services that we offer.

    The services and charges affected include new water and wastewater connections, new water mains and sewers, income offsetting, and infrastructure charges.

    For further information please refer to our comprehensive charging document and accompanying technical guidance via the links below. We have also created a new calculator, which will allow you to interactively generate an initial quotation for your project. 

    The new calculator is in beta testing, for any queries please contact
