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.

It is worth noting that Ofwat have made changes to developer Charging Rules applicable from 1st April 2025, the most notable of these are:

• The provision of Income Offset will cease, thereby water and sewerage companies will no longer make an Income Offset payment to developer customers.
• A common framework for Environmental Incentivisation with the aim of greater water efficiency and/or more sustainable drainage for new homes. Environmental Incentives will be solely funded by a new Environmental Component, all developers will pay a relatively small environmental component each time a property is connected to the network - one for water and one for wastewater

We’ll be holding several developer customer engagement sessions during the Summer & Autumn of 2025 in readiness for our 2026-27 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
