Connection for a single commercial property up to 69KVA

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.


A small commercial connection application is for a one off single or three phase supply rated up to a maximum 100A per phase for non-domestic premises. If you require a higher maximum power or multiple commercial connections please visit the “Connections for single commercial >100A or multiple commercial premises” webpage.

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.


Some methods of building do not allow Protective Multiple Earthing (PME), in particular multi-occupancy steel framed buildings. In such cases alternative earthing solutions can be provided by your electrical contractor.

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 and a Site Layout Plan.

You will also need to provide details of potentially disturbing equipment such as motors and welders; a template to submit the necessary information can be provided on request.

The following flowchart identifies what will happen once we receive your application form.
