Across the water industry the charges set by water companies for developer services activity (often referred to as 'new connections') are regulated by a series of rules which are set by Ofwat.
More information on these rules can be found at the bottom of this page. We publish our charges annually (normally around 1 February) ready for use between 1 April and 31 March.
Our charges fall into the following categories:
|
Charge |
What it covers |
How is it charged and when is it paid |
Which customers pay this |
|
Application or enquiry fee |
Upfront administrative activity from logging an application through to providing a quote or design |
Charged per application and paid upfront when you issue your application |
All customers pay this charge. The value of this charge is dependent on the type of application for example a service connection application fee is cheaper than the fee for a new mains scheme. |
|
Service connection charge (site-specific construction) |
The planning and delivery of constructing new service connections including local authority permitting costs for working in the highway and traffic management |
Charged on a menu of rates based on the scope of the works required and paid for after you have received your quote from us but before we carry out the construction works |
Those customers requiring new service connections into our network (including replacement connections) whether this is just one connection or many hundreds on a development site. |
|
Mains laying charge (site-specific construction) |
The planning and delivery of laying new mains on development sites or feeding a new development including local authority permitting costs for working in the highway and traffic management |
Charged on a menu of rates based on the scope of the works required and paid for after you have received your quote from us but before we carry out the construction works |
Those customers requiring a new main, typically a new main is installed where a number of new properties require a new water supply. It is unlikely that those customers requiring only a few service connections will pay this type of charge. We also use our mains charges when providing quotes for connecting infrastructure for Self Lay provider and NAV sites. |
|
Infrastructure charge |
The investment we need to make in our network to cater for the increased demand from new developments |
Charged per property (or per plot) and typically paid after the connections have been made (you can pay beforehand if you wish) |
The majority of customers pay this charge. If we are providing a connection to a location where there has been previous usage in the past 5 years (ie a renovated building/site, replacement connection) then no infrastructure charge is due here. |
|
Water efficiency discount |
Discount against the infrastructure charge for properties which show reduced water supply demand |
Applied per property (against the infrastructure charge for that property) and at the same time that the infrastructure charge is paid |
Any customer who is applicable for the infrastructure charge (the majority) and who has built to meet the demand requirements |
|
Environmental component |
A charge which recovers the revenue required to fund the discounts provided to developments which have been built to meet our water efficiency scheme criteria |
Charged per property (or per plot) and paid alongside the infrastructure charge |
Any customer who is applicable for the infrastructure charge (the majority) |
