• Have you got local authority planning approval? You will need this before applying for a new water connection. 

• Do you know what size of connection you require? A domestic property normally has a standard 25mm water pipe.

• Do you know where the nearest water main is to connect to? This information is available on local maps which are offered by a number of companies including United Utilities, if you would like to buy a water plan from us please see our Property Searches service.  
  
  
• Do you need a temporary supply? If so, please be aware it is only valid for 12 months

• Do you know the history of the land you're building on? If it’s not greenfield land and has been previously occupied, you will need to engage a geo-technical specialist to complete a Risk assessment (PDF 110 KB opens in a new window) which should be submitted with your application for a water connection. 

• If your development is for domestic dwellings and you are using water efficient fittings and appliances, you may be eligible for a reduction on your water infrastructure charges. You can check on our Water efficiency calculator (PDF 1,702 KB opens in a new window).

• If your development is for multiple domestic dwellings within one building and you will be installing a bulk meter that will be dealt with by a management company, please provide the details of the management company including their company registration number. This is needed before we can provide a quote.
  
  
• In order to connect to a water main you may need to lay your pipework through land that you don't own. It would be worthwhile at this stage finding out who owns the neighbouring land as you will need to get permission to lay a water pipe in their land, and you will also need access to repair to maintain it.

When you’re ready to apply for a water connection please send us the following:

• A completed application form, please choose the form for your development.
  
  You can print the form or complete it on your computer and email it to us, please download a copy and save it before filling it in.
  
  
• Application for a water supply for houses 
  (This replaces the previous AWS1 Application for 25mm connection to an existing main)  
• Application for a water supply for flats and apartments (PDF 496 KB opens in a new window).
  (This should be used instead of the previous AWS2 Application for 32mm connection to an existing main.)
• Application for a water supply for commercial property (PDF 485 KB opens in a new window).
  (This should be used instead of the previous AWS2 Application for 32mm connection to an existing main.)

• A site location plan (including site address, postcode and x - y co-ordinates).

• The planning reference number and status of planning application.

• A full site layout plan clearly showing the proposed route and point of entry for the new connection.  

• The application fee of £115.20 (incl VAT) for the first connection plus an additional charge of £48 (incl VAT) for each subsequent connection. For more information please refer to our charges scheme, details on how to pay are in the application form and the charges scheme.

If you don't need your water supply within six months, we can provide a free estimate.

We’ll review your application and visit your site to assess your connection requirements. Within 28 calendar days we’ll send you:

• A fixed quote specific to your project.

• A scheme drawing showing the point of connection.

• Relevant schematics for pipework installation. 

If you choose a fixed priced quote, the price will be valid up to the end of March 2023. Any connections made after this date will be charged at the new rates in our 2023/24 charges scheme.

When laying your pipes we would suggest using an approved plumber. It will mean your pipework is compliant with the regulations around the supply of water, and it will speed up the connection process.

If you're happy with the quote, please sign and return the quote acceptance form.

Before asking for the connection to be made, you’ll need to complete all work required on site. This will be detailed in the pipework specification drawing supplied with the quote.

Before we can connect your supply, we need to check your pipe work meets industry standards. We will check:

• Have you laid the correct size pipework?
• Is the pipework the correct material for the ground conditions?
  Number of supplies
• Is the pipework laid at the right depth?
• Has the pipework been brought out to the correct point
  of connection?
• Is there sufficient pipework coiled up at the boundary and is it
  capped off with a mechanical stop end?
• Is the meter manifold installed (internal at point of entry or wall
  mounted box)?
• Is the external control box installed?

For 25mm or 32mm pipes

If you’ve used a WIAPS (Water Industry Approved Plumbers’ Scheme) plumber, you can provide a WIAPS certificate.

If you’ve used a non-WIAPS registered plumber we will need to inspect the pipes.

For pipes 63mm and above

We need to inspect all pipework that's 63mm and above, we will also require a pressure test certificate and a chlorination certificate.

If the supply is 80mm or greater we will also need to see the laboratory sample pass results.

Let us know when the pipework is ready for inspection, giving us at least five days’ notice. Please note if the inspection fails, and a re-inspection is required, there is an additional fee of £90 (incl VAT).

Please also send us written confirmation of the new postal address, on letter headed paper, from the local authority (street naming and numbering department).

Once you’ve supplied all of the information above, please complete a Request for work form (PDF 253 KB opens in a new window). This is a checklist to ensure that all necessary work has been completed.

Once we’ve received all of the information outlined above, we’ll make the connection and install the meters. This will be within 21 calendar days, subject to any traffic management restrictions which will be detailed in your quote. 

When the connection has been completed we will send you an invoice for the work.

Once the connection has been made and the meter installed, the information will be sent to our billing department who will create the account for the property. It will then be ready for the new occupier to register with us.
