Connection for a single & multiple commercial properties > 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 large commercial connection application is for a one off commercial or industrial supply rated greater than 100A per phase or multiple commercial supplies of any size. If you require a one off commercial connection rated at or below 100A per phase, please visit the “Connections for single commercial property up to 100A per phase” 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 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 landownership 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?

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.
