Builders & developers - Water

Our Water Developer Services team are dedicated to supporting you with supplying water to your new house build or development. Here you will find the right guidance and application forms for water connections and laying a new water main.

Our Obtaining water supplies for new developments guidance document will also help you decide how best to obtain water for new house builds/developments within a United Utilities area.

We have a responsibility to ensure water delivered for domestic purposes is of high quality. Where new water pipes are to be installed in land that is, or may be, affected by contamination, a risk assessment for water pipes should be provided to us to ensure that the correct type of pipe is selected. Please see our section on water risk assessments on our Planning page for more information.

Connections

We understand that getting a water supply at the right time during the construction of a new development is a key part of your build plan. Our dedicated Developer Services team provides a one-stop service, from initial enquiry through to final connection, to ensure that your water connection is made when you need it.

We also understand that the rules and regulations for water connections are complex. That's why we're here to provide all the help and information needed to get your new water connection set up.

Details of charges associated with making a connection can be found in our Standard Connection Charges document.

New household supplies

To help us quote for your new connection to our existing water network, we have an application for standard household supply (AWS1) form. This form is for 25mm standard connections only. If a trough, irrigation system or temporary water supply is required then you must complete our application for a trough, irrigation system or temporary connection (AWS3) form.

We charge an application fee for providing written quotations. Details can be found on our Standard Connection Charges sheet.

When you are ready for your new connection, please complete the Service connection request for work form.

To obtain a quote for a connection to a new or modified existing building that is planned to have several separate dwellings, we have an Application for a non-standard connection AWS2 form. This form is required where the incoming supply is 32mm in diameter, or above.

In some developments we will need to understand the internal water distribution arrangements so that the correct water metering can be installed.

Service Pipe Installation Developer Services Electronic Register (SPIDER)

Cessation of SPIDER training and alternative arrangements

As part of our ongoing commitment to build on the benefits driven out of our continuous improvement programme, the SPIDER training programme has been closed to make way for the Service Pipe and Meter Housing Installation training Certified by BPEC. The BPEC certification is recognised by Water UK as complementary to the water regulations course used to gain WIAPS registration.

To gain this certification you will need to find an approved centre via www.bpec.org.uk and locate your nearest centre.

Required as an accompaniment to WIAPS for self-certification of water services in the UUW region

If you currently install, or employ installers to lay, water supply pipes for domestic housing, you must make arrangements to ensure you/they are registered SPIDER or BPEC-registered in order to self-certify installations or, must be able to provide alternative proof of competence and understanding of United Utilities' specific conditions of service. WIAPS certification will still be required in order to provide assurances that the installation has been laid in line with water regulations. We will reserve the right to refuse connection of any self-certified installation that has not been fitted in accordance with the water supply regulations, or our conditions of service.

SPIDER registered installers

The current SPIDER register remains open to allow those installers who have undertaken the training to continue operation under their current valid registration numbers until expiry. As we no longer operate the SPIDER training course, we will not be able to accept any new applicants onto the register.

Here is a list of SPIDER registration numbers.

Please remember that you can contact us by calling 0345 072 6067, Monday to Thursday from 8am-5pm; and Friday from 8am-4.30pm; or by emailing DeveloperServicesWater@uuplc.co.uk to get a quotation for your new connection, or advice on your new connection.
