Our Standard of Service

Here at ESP we value the services we give to our customers. Ofgem, the industry regulator, sets guaranteed standards to ensure all Distribution Network Operators (such as us) meet customers’ needs. If we fail to meet these standards you are entitled to receive a payment.

Guaranteed Standards of Service

In line with Section 39A (5) of the Electricity Act 1989 (as amended by the Utilities Act 2000), any guaranteed standard payments you receive will not prejudice your entitlement to any other remedy or action that may be due to you because of our failure.

Sometimes the guaranteed standards may not apply, due to, events beyond our control, such as the actions of third parties, being unable to gain access to premises or our own equipment, being unable to identify the customers affected by supply interruptions and in some cases severe weather.

If any of these exemptions are invoked, we will need to demonstrate that we had taken all reasonable steps to prevent the exceptional circumstances occurring and to prevent failure. If you are supplied via a landlord’s private cable or a private network (i.e. one that is not operated under an electricity distribution licence), these standards do not apply.

How much you are eligible to claim in compensation under the Guaranteed Standards depends on many factors, including:

  • the cause of the outage
  • the amount of time you were off supply

For further information on our standards of service and a full list of the compensation payments you could be eligible for, please download an electronic copy of our Electricity Standards of Performance is available here, and our Gas Standards of Performance here.

A hard copy of our Code of Practice can be provided free of charge. Please get in touch with us to request this via our online form or call us on 01372 587 500.

You can also find further information about your rights on Ofgem’s website here.


If you feel that you may be liable for compensation after any inconveniences you may have experienced, such as a power cut, please get in touch with us.


ESP always aims to provide the highest standard of customer service. Where you do experience a problem with the level of service provided by us, we will strive to make things right as quickly as possible.

Your feedback is important to us as it helps us to improve our processes and train our staff to ensure the highest standards are met.

If you’re unhappy with the service you have received from ESP, please send us a message or call 01372 587 500. There are a few pieces of information that our customer service operatives may ask you:

  • Name / Company name (if applicable)
  • Address
  • Telephone number
  • Email address
  • Full site address (if different from your correspondence address)
  • Any reference numbers you may have previously been provided with

You will hear back from us within 24 hours of raising your complaint, and we will provide a response to your complaint within 5 working days.

If you are not satisfied with the way in which your complaint was handled or the response provided by our Customer Service team, you have the right to escalate your complaint to ESP’s Network Manager.

You can find a copy of our full complaint process here.

In the event that your complaint has been through our escalation process and you are not happy with how we’ve dealt with your complaint, there are numerous ways that you can ask for help such as getting in touch with Citizens Advice  consumer service, or by seeking the assistance of Ombudsman Services. 

Ombudsman Services

We will always do all we can to successfully resolve your complaint to your complete satisfaction. However, if eight weeks have passed since you raised a complaint and you believe that it remains unresolved, OR if you have been notified by ESP that there is nothing more we can do for you, you can refer to, and seek the assistance of Ombudsman Services. Ombudsman Services is an independent body who will assess your complaint. The service is free of charge and the decision made is final and binding on ESP, but not on you. You can contact them via the following methods:
