No. Procedure Time to Complete Associated Costs
1 Submit an application to UK Power Networks for an electricity connection and await a quotation and connection offer

The application can be submitted online, in person or by mail. One has to attach with the application: completed initial enquiry form if initial enquiry was made, load details and detailed site drawings.

At this stage the applicant can choose either UK Power Networks or a qualified contractor to design a part of the network extension while only UK Power Networks can do the design of certain parts of the network extension and design of upstream reinforcement works. If the design is carried out by a qualified contractor and not by UK Power Networks there are additional procedures for approval of the designs. Majority of the clients choose UK Power Networks to complete all parts of the design.

UK Power Networks will do the assessment and design which will result in the budget estimate as well as the Construction and Adoption Agreement which will include the formal offer to connect.

Since September 2008 UK Power Networks has not charged assessment and design charges in advance but they have been included in the final connection payment as an overhead cost. This follows a consultation by the UK energy regulator Ofgem. Ofgem is currently considering new regulation concerning assessment and design charges.
A budget estimate and connection offer is free of charge.

By law all of the quotations should be provided as soon as reasonably practicable with an absolute backstop of 90 days – this is a requirement of Standard Licence Condition 12 of the Electricity Distribution Licence.

* 2 Await and obtain an external inspection carried out by UK Power Networks

An external inspection is necessary for preparation of the technical study and an estimate. During the inspection the utility ensures that the location is OK for their equipment (service cut-out/substation etc). It is recommended that somebody from the applicant’s party is present during the inspection.

3 Await completion of the external connection works carried out by UK Power Networks

Some of the external connection works which are contestable (not all works are contestable) can be performed by an approved contractor or by UK Power Networks. If contestable works are performed by a subcontractor additional procedures associated with inspections and testing of the contractor’s installation by UK Power Networks are required. In the majority of cases customers choose UK Power Networks to carry out all the external connection works.

Given the case assumptions the most common arrangement would be either 1) 200 amp TP & N (three phases and neutral) service off a passing LV main or 2) installation of a substation.
The utility obtains the excavation permit at the local authority or Highways Agency or specific body such as TFL in London.

All material for the connection is available 50% of the time. Customer has to buy material for the external connection works only for wiring beyond the meter to the warehouse and the cable ducting for laying on their private land to the boundary with the highway.

If the customer rating is sufficiently high no security deposit will be needed.

* 4 Await issuance of a supply number by UK Power Networks and appoint an electricity supplier

UK Power Networks Energy has to issue supply Numbers (or MPAN’s) before the connection works are completed so that arrangements can be made with an electricity supplier and meter operator.
As a supplier, UK Power Networks (the customer may not choose UK Power NetworksE to be their electricity supplier, there is a competitive market) needs to be appointed by the customer on receipt of the MPAN (metering point administration number) from the network operator. The supplier will register the MPAN.
UK Power Networks will co-ordinate metering, energisation and application of energy rates from the date of the connection be made live. The supply contract start date is aligned with connection energized date. The supplier will need to receive an estimate, or could work with the applicant to develop a load profile to be able to provide a supply contract.

* 5 Appoint a meter operator, await installation of a meter and internal wiring inspection by UK Power Networks and electricity starts flowing

The metering industry in the UK is an open competitive market, and the applicant can choose their own Meter Operator. The applicant has to sign a contract with the chosen meter operator.
The inspection of the internal wiring is done when a meter is installed. Inspection of internal wiring is done through a visual inspection by a meter operator and an installation certificate is provided to the electricity provider. It is a good practice that somebody is present during the installation of the meter/internal wiring inspection.
In the UK, the DNO only undertakes the work up to the cut-out. All internal works are the responsibility of the customer who must appoint a qualified electrician. All internal works must be carried out to BS 7671 standard and the Meter Operator (who works on behalf of the supplier) will need to see a BS 7671 certifcate before the meter will be attached and the connection energised.
There is no specific charge for the meter, but the customer will be required to appoint a meter operator and subject to measurement class there will be the annual operations and maintenance charge.

The metering must be installed before a supply of electricity can be provided.

The electricity can start flowing on the same day the external connection works are finished providing the supplier and the metering operator have sufficient notice.
