The following information sets out useful documents and details to help you get the best out of your relationship with us, as well as help you keep abreast of your regulatory requirements.

Back-billing commitmentsBack-billing commitments

In situations where you have not been charged or you have been charged incorrectly for your energy use, we may send an invoice to recover these costs. This is known as 'back-billing.'

We’re committed to delivering the highest standards of customer service, and recognise our responsibilities with regards to back billing.

If you are a micro business customer, we won't bill you for unbilled energy consumption in excess of 2 years, if it is our error.  Download the Voluntary Standards for Microbusiness Energy Users to read about the responsibilities we have as a supplier, and for advice on how you can prevent back-billing.

​A microbusiness is defined as a business which:

  1. Consumes no more than 293,000kWh of gas or 100,000kWh of electricity each year; or
  2. Has fewer than ten employees and an annual turnover not exceeding €2m

These standards have been agreed with Energy UK and the Industrial and Commercial Shippers and Suppliers Group (ICoSS). Both organisations promote good practice within the energy sector.

Visiting your premisesVisiting your premises

On occasion, representatives of DONG Energy may need to visit your site in order to potentially carry out any of the below:

  • Site surveys
  • AMR installation
  • Meter exchanges
  • Routine maintenance visits

Arranging the site visit

If a visit is required, our representatives will always attempt to book an appointment with you in advance, by telephone.
When our representatives telephone, they are required to clearly explain their reason for contacting you, making it clear they are acting on behalf of DONG Energy. Additionally, they are required to confirm:

  • Site address details
  • Access requirements
  • Individual customer or site requirements
  • Passwords or additional security arrangements

If you require a risk assessment and method statement, please request this during your discussions with the representative. 
If the representative is unable to make contact with you, they will attempt to make the visit to carry out these works.

On the day of the site visit

If an appointment has been agreed in advance and it is possible to do so, the representative will telephone on the day of the appointment, prior to the visit to provide you with an estimated time of arrival.

When the representative arrives on-site, they are required to:

  • Be polite and professional
  • Wear appropriate Personal Protective Equipment (PPE)
  • Show you their ID / accreditation upon request
  • Explain the reason for the visit, confirming it is appropriate to proceed before starting any work.
  • Keep you informed about the progress of that work, which includes advising you at any point if any technical issues or concerns arise.
  • Ensure that the work area is clean and tidy before leaving, removing all tools and materials
  • Confirm that you are satisfied with the work carried out and help with any other questions that you may have.
  • Record your comments or feedback, in order it pass them back to DONG Energy. 

Work carried out at your premises by other third parties

On occasion, representatives or agents that are unrelated to DONG Energy may arrive at your premises to review your metering supply infrastructure. These third parties will usually be acting on behalf of the companies that are responsible for the Distribution infrastructure (i.e. National Grid, Scotia, Southern, Wales & West or Northern Gas Networks).

We cannot account for all agents of all parties that carry out work on the UK’s energy infrastructure, however any reputable agent or Reasonably Prudent Operator (RPO) will be happy to share accreditation information with you, and provide you with the means to check their credentials and reasons for attending your site. Once confirmed, the agent will then need to proceed with their work. 
DONG Energy does not have direct involvement with these parties, therefore it is important that you ask them to provide you with their credentials.

Providing feedback

You can provide feedback in the following ways:

  • Contact your DONG Energy Account Manager or call our customer service team on 0800 0568 111.
  • Complete a Customer Satisfaction questionnaire. (You will receive this - or be invited over the telephone to participate).

How to report energy theftHow to report energy theft

​Theft of electricity and gas costs UK energy consumers an estimated £400 million every year. It also presents a serious safety hazard, endangering the public, energy industry workers and the emergency services. Energy is usually stolen by interfering with electricity or gas meters, which can cause electrocution, fires and explosions. Energy theft is also increasingly associated with wider criminal activity.

In September 2016, Crimestoppers launched the Energy Theft Tip Off Service (ETTOS). This service allows members of the public to report suspected energy theft anonymously, using a 24-hour telephone line or by completing an online form. To find out more, visit the ETTOS website Stay Energy Safe

If you are concerned about energy theft, you can also contact our Customer Service team on 0800 0568 101.
