For a new water connection to a single domestic dwelling, youll need to get in touch with your regional water supplier. Many companies recommend submitting an application 3 months in advance, so if you need a temporary supply on site while you build, make sure you leave yourself plenty of time.
Things are a bit simpler with the water companies because, unlike gas and electric suppliers, the company making the connection also owns the meters, supplies the water and sends you the bills. On the flip side this means there's no choice of who supplies your water.
The connection process varies between water companies particularly in regards to your responsibilities, so make sure you check the details with your local supplier.
Temporary Supply Pipe
The biggest difference in this process is in how water companies discharge their obligations under the Water Supply Regulations 1999. These regulations were designed to ensure the safe and efficient distribution of water, preventing waste, contamination and misuse.
Whilst it is up to you and your plumber to install everything correctly, it is up to the supplier to enforce compliance with the regulations. This could be done through your use of an accredited contractor such as through the Water Industry Approved Plumber Scheme (WIAPS) or by the supplier carrying out inspections of the supply pipe and the plumbing installation at your property before making the connection. Once again, check with them for details.
Costs for a new water connection can vary greatly and are dependent on a range of factors such as where the main is in relation to your entry point and whether the supply company has to excavate unmade ground, pavements, or roads to make the connection.
There are two main components to the connection charges. The first of these is the connection charge itself which you can expect to be in excess of £400 and the second is an infrastructure charge which is levied to take account of the additional load of a new user on the entire water supply and waste water systems. The infrastructure charge is normally around the £300 mark for water and the same for waste water.
At the time of writing, if you are self building, new water and sewerage connection services are zero rated for VAT and the charge shouldnt be added to your quotation.
If your new build property is a long way from a public main and it becomes necessary for the water company to extend the main, these costs will be passed on to you although an adjustment will be made to reflect the value added by future revenue generation from the additional main and connection.
