Connection for up to 4 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. These are valid for 90 days and the works should normally be completed within 90 days from the date of acceptance. 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.

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.
