Connection for 5 or more domestic properties

How much is a new connection?

Each application is individually assessed and costs are determined in line with our Connection Charging Methodology Statements.

Typical Costs and Timescales for connection

We have provided a table of average costs and timescales, available here.

Alternatively you can use our Interactive Costing Tool to calculate an indicative price for your site.


Domestic connections are usually single phase 15kVA and rated up to 60A. If you require a higher maximum power for each property you will need to let us know, your electrician should be able to calculate this for you.

We will make an assessment of the works required and associated costs following receipt of an application form. Once we have completed our assessment we will send you a quotation which will be valid for 90 days.

The works should normally be completed within 12 months of acceptance, although a longer timescale may be agreed for significantly larger developments. This is subject to change; for example, we may need to obtain permissions from third party landowners or the highways agency prior to commencing any works. We may also need to obtain specific legal rights and/or land ownership in relation to our assets being installed within your own land boundary.


We will include within the Connection Offer a series of milestones that you must meet or risk losing your Offer. The milestones set prescribed periods that take effect from the acceptance date of the Connection Offer and indicate certain key stages in the scheme’s development that you must meet. The milestones provide a mechanism under which we can monitor the progress of a scheme and, if any milestone is missed (or likely to be missed) we can liaise with you to discuss progress.

For more information on the background to the introduction of milestones, the typical milestones and timescales included within a Connection Offer and how these are managed by WPD, please see our guidance on Extension of validity acceptance.

Will my quotation include everything?

To ensure your safety when digging on your own land, please view our Public Safety Advice webpage.


For domestic connections, we will normally install Protective Multiple Earthing (PME). Some methods of building do not allow PME, in particular multi-occupancy steel framed buildings, in which case an alternative earthing solution can be provided by your electrical contractor. If we identify that PME cannot be provided for your premises, we will discuss this with you.

What happens next?

Once you are confident that you wish to proceed, please complete and submit an application form. You will need to include a Location Plan, Site Layout Plan and Manufacturer’s specification sheet if you are installing electric boilers, heat pumps, generation or similar electrical equipment. The following flowchart identifies what will happen once we receive your application form.
