New connections charging

New connection charges

Welcome to Severn Trent’s new connections charges.   

Our charges have been designed in line with the charging rules introduced by Ofwat in 2018, ensuring our developer customers experience greater simplicity and predictability than in prior years.

We’ve built our new connections charges with four principles in mind:

Providing stable and predictable charges

We recognise that our developers’ value stable and predictable charges so throughout our Charging Arrangement Document we have published, where applicable and appropriate, fixed charges for water and sewer connections which should allow a developer to work out a reasonable estimate of what they will pay. We also take all reasonable steps to ensure that the value of our charges do not fluctuate year on year.

Ensuring transparent and customer focused charging

We’ve published, where possible, fixed charges and defined both how we’ve calculated our charges and how we will apply our charges for activities required on site, enabling our developers to make a reasonable estimate of what they will pay for water and sewer connections. We have also included all charges that could be paid within our Charging Arrangement document to ensure we are completely transparent with no surprises. 

Ensuring fairness and affordability

To ensure all developers get a fair deal, both now and in the future we’ve developed our charges so that they do not discriminate between our different developer customers - Self-Lay Providers (SLPs), New Appointments and Variations (NAVs), national developers, smaller house builders and individual customers. Our new connections charges apply to all our developer customers, regardless of the number of properties connected to our network. We’ve engaged with our different types of customers to ensure market acceptability for our proposed charges.

Providing environmental protection

Our infrastructure discount scheme encourages developers to build sustainable properties which save water usage and reduce the amount of surface water going into the public sewer reducing the risk of flooding.

Our 2019/2020 charges

We’ve reviewed each of our new connections charges and you can find more information in our latest Charging Arrangement Document (PDF). Throughout our Charging Arrangement Document the term “developer” refers to all of our customers who are building and developing properties. When reviewing these charges we’ve maintained the balance of charges between our developer customers and other customers, such as our household bill payers. Our Charging Arrangement Document not only tells you about our 2019/2020 new connections charges, but also about the process you need to follow to get a new connection onto Severn Trent’s water and/or sewer network - helping you to make an informed choice as to who does the connection work. We’ve recently received customer feedback which asked for further information on protective pipework, so we’ve created a document that explains our protective pipework charges for new mains requisitions.


Working in partnership

While we were reviewing our new connections charging framework we worked closely with Water UK and consulted with developers, self lay providers (SLPs) and New Appointment & Variation (NAVs), along with their trade bodies and representatives, as it was important to hear what our customers thought about our proposals. Alongside this, our new charging framework has been through a rigorous assurance process and we have provided the Water Services Regulation Authority with an assurance statement (PDF) and statement of significant changes (PDF) from our Board of Directors.

Our 2018/2019 charges

We are required to publish our new connections charges by 1 February ready to come into effect on 1 April therefore the information above relates to our 2019/2020 charges.
