New connections charging

Welcome to Severn Trent’s Developer Services charging information page.

Our charges are renewed each year, applicable from 1^st April through to 31^st March. They align with our Regulators (Ofwat) charging rules for new connection services and have been developed under the provisions of the Water Industry Act 1991.

Our charging arrangement document sets out the charges made by us for services relating to new connections to our water and sewerage network or works required to our network because of a development, while carrying out our actions as a water and sewerage undertaker in line with our Instrument of Appointment.

We strive to offer developer customers value for money, whilst recovering all reasonable costs, and present the relevant charges in a manner which is easy to understand.

We create our developer charges with the following five principles in mind:

Every year we renew and republish our new connections charges that are applicable for a 12-month period commencing on 1 April.  Here is our latest Charging Arrangements Document (PDF) (opens in new window). Throughout our Charging Arrangements Document the term “developer” refers to all customers who are building and developing properties. 

To provide visibility of annual charges we publish our Charging Arrangements Document in the February prior to the charges coming into effect on 1 April.

We’ll be holding several developer customer engagement sessions during the Summer & Autumn of 2024 in readiness for our 2025-26 charges. We would love to hear your feedback and suggestions so please do let us know if you would like to attend one of these sessions by emailing developercharges@severntrent.co.uk

It is also worth noting that from 1^st April 2025 Ofwat intend to make several changes to the Charging Rules, to include the following:

-          The provision of Income Offset will cease, thereby water and sewerage companies will no longer be able to make an Income Offset payment to developer customers.

-          Changes to Environmental Incentivisation, whereby the aim is to introduce a common approach across England that continues to adequately support sustainable development and encourage innovation.
