  • 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


    We made some minor revisions to our charges in March and June 2018 after the original published on 1 February 2018. Where the changes were in customers’ benefit we made the changes immediately rather than wait, thereby creating an “interim” version of the charging arrangements between 1 April and 31 May. We consulted on the full scope of the changes between 28 March and 28 May. The remaining changes came into operation on 1 June. The full scope of the changes is as follows:

    • The inclusion of “no excavation and refill” connection charges within table 4-2
    • The revision of new mains connection charges in table 6-1
    • A change to the basis of the charge for decommissioning redundant pipe to per linear meter in tables 6-5 and 8-2 (plus the charge originally in table 8-5 moved to 8-2)
    • The inclusion of Deed of Grant and Land Transfer fees for Sewer Adoptions to table 8-4
    • The inclusion of laying sewers in gardens in table 8-2
    • The inclusion of a Type 3 Sewer Pumping Station in table 8-2
    • Plus a number of minor grammatical changes and clarifications
