Back billing and DONG Energy Sales

DONG Energy Sales is signed up to the Energy UK Back Billing standards and currently limits their micro business back billing to two years.

It is important to note however that this limit only applies if the customer is deemed to have done all that can be done to avoid the back billing in the first place and where the supplier or industry processes are clearly at fault.

Like DONG Energy Sales, many suppliers have voluntarily limited their back billing rights to two years and in some cases a single year.

However equally a number of suppliers are not signed up to the Energy UK Back Billing standards and therefore, under the Limitations Act, are able to back bill their customers for anything up to 6 years.

DONG Energy Sales are therefore one of the stronger suppliers in this area. To find out more visit our Guide to Back billing.

DONG Energy Sales and Letters of Authority

In order to act on your behalf in securing your business a great energy deal DONG Energy Sales require us to have a signed Letter of Authority from yourselves.

eSign - Fast, Convenient Online Approval

The fastest way to authorise us to work on your energy supply arrangements is to use our eSign service to agree our Evergreen Letter of Authority.

We’ll take care of all correspondence, handle all the loose ends and enable you to focus on establishing your business in its new premise.

And what’s more once your contract is in place we’ll manage your supplier relationship from beginning to end, all part of the Lloyd Energy service.

Change of Tenancy and DONG Energy Sales

Moving into a premise is known as a Change of Tenancy in the business energy market. It has also been termed a Change of Occupier or is known by its acronyms CoT and COO. However it is referred to, the opportunities it opens up are the same.

This is great news for deal seekers. Whilst the existing supplier is obliged to continue to provide energy to the new occupier, the occupier is not obliged to take out an extended contract with that supplier.

Indeed a Change of Tenancy customer has total freedom of movement and is free to accept a contract with a supplier of their choice

There are however of course a number of rules and requirements.

Firstly, as the new occupier, if you use energy you will need to pay for it, regardless of your contractual status.

Secondly, you will need to identify as quickly as possible the identity of the existing supplier

Thirdly, you will need to field calls from sales organisations and the existing supplier themselves offering you contracts of varying lengths to continue or to begin to supply the premises.

As a result as a new occupier you will need to agree a new contract either with the existing supplier or with a new supplier of your choice.

Not only that but you will need to inform the existing supplier as quickly as possible that you are the new tenant to prevent you being held liable for charges incurred by the previous occupier should they not have ended their agreement satisfactory.

It can prove a real headache knowing whom to trust – whether it’s the old tenant, the landlord the current supplier, the pushy salesman ringing, knocking and emailing, the prospective new suppliers.

That’s where Lloyd Energy comes in, by working on your behalf, identifying your existing supply arrangements, reporting your change of tenancy, ensuring you are not held liable for costs not incurred before your occupation and benchmarking contracts for your selection we can help you save time, money and a whole lot of stress.


DONG Energy Sales sends their renewal letter to customers around 120 days in advance of the contract end date. This will contain DONG Energy Sales’s proposal for your rates for the coming period. It will provide a single price. It will however not be the most competitive price available in the market as the renewal letter is designed for customers who don’t use an energy broker and as such are priced at a higher level than can be obtained in the market.

Terminating with DONG Energy Sales

You are required by DONG Energy Sales to provide written notice at least 30 days before your contract ends of your intent to terminate your contract at the end of its fixed period.

No termination is required for customers who consume in excess of 3,000,000 kWh per annum

Rollover contracts and DONG Energy Sales

For customers consuming less than 3,000,000 kWh per annum DONG Energy Sales operate a policy of selling auto-rollover contracts. If you fail to terminate your existing contract more than 30 days ahead of your contract end date you will be rolled over for a fixed term of 12 months.

By using Lloyd Energy you can avoid the costly mistake of falling into the rollover trap and paying premium rates for 12 months.

To find out more visit our Guide to Rollover Contracts.

Terminating but remaining on supply with DONG Energy Sales

If you have provided termination notice to DONG Energy Sales and expressed your intent for freedom of movement at contract end but you fail to leave DONG Energy Sales’s supply you will be placed on DONG Energy Sales’s out of contract rates.

Don't be caught out! By using Lloyd Energy to manage your energy contracts we will terminate and manage your new contract seamlessly to ensure you avoid penalty rates.

DONG Energy Sales and Out of Contract Rates

DONG Energy Sales describe their out of contract rates as ‘deemed rates’.

These are 5.5p/kWh and an AQ dependent Standing Charge starting at 150p/day.

Even one week exposed to this level of charges mounts up, that's why clients taking our contract life management service makes sense: removing your exposure risk and letting you focus on your business confident in the knowledge that your energy contracts are in safe hands.


DONG Energy Sales operate a policy of billing their customers on a monthly basis.

DONG Energy Sales operate a Monthly, Fixed Direct Debit meaning the amount you pay directly relates to the consumption you provided at the point of contract.

DONG Energy Sales' standard payment terms are 12 days after invoice, or the 20th of the month, whichever is the later.

DONG Energy Sales does offer cash/cheque payment terms however this is only done so in limited circumstances for Limited companies and is subject to revised pricing.

To find out more visit our Guide to Supplier Payment Terms.

DONG Energy Sales provide online billing functionality as standard within all of their contracts meaning the end of paper invoices for their customers whilst providing convenient access to their account data.

If you have a DONG Energy Sales invoice and are in doubt feel free to fax us your bill on 0208 328 7788 or send it to and we will help locate the information for you.


DONG Energy Sales & Smart Meters

In line with the mandated rollout of smart meters DONG Energy Sales installs meters for gas customers consuming more than 732,000 kWh per annum.

DONG Energy Sales also installs smart meters as part of their contract terms for gas customers consuming less than 732,000 kWh per annum.

DONG Energy Sales will however inherit smart meters but will not support the meter's smart functionality.

This means the meter will be treated as 'dumb' and will require manual meter reading.

For more information on Suppliers’ policies on smart metering visit our Guide to Suppliers & Smart Meters.

DONG Energy Sales & New Connections and Upgrade services

DONG Energy Sales currently only offer new connections and upgrade services to customers when they take out a new contract.

If this doesn't suit your requirements, to find out which suppliers meet your connections needs call us on 0800-208-8301. Go one step better and by appointing Lloyd Energy to manage your energy contracts you can take advantage of our management fee free new connections and upgrades offer.

DONG Energy Sales & IGT Meters

DONG Energy Sales support meters supplied via IGT networks (Independent Gas Transporter). If your gas supply is delivered via an IGT network then unlike some suppliers DONG Energy Sales can offer you a gas supply contract. However the meter will require a bespoke priced gas supply contract.

DONG Energy Sales & Supporting Meter Types

DONG Energy Sales only support Half Hourly (HH) electricity meters where they are linked to large consuming gas customers.

DONG Energy Sales do not support Maximum Demand (MD), Seasonal Time of Day (STOD) and standard profile meters nor 'related' meters.

DONG Energy Sales support all gas meter types including ‘aggregated’ meters. This means whatever gas metering system you have, even if it is supplied via an IGT network, DONG Energy Sales can support it.


DONG Energy Sales do not currently provide renewable or green energy products within their portfolio however they do offer smart metering solutions to help your business use less energy.

DONG Energy Sales and Fuel Mix

As a supplier of gas only, DONG Energy Sales are not required to file a fuel mix disclosure.

However for the 2013/14 period the national average was:

  • Coal: 34.0%
  • Gas: 25.6%
  • Nuclear: 21.6%
  • Renewable: 16.7%
  • Other sources: 2.1%

Producing CO2 of 428g/kWh and High Level Radioactive Waste of 0.0017g/kWh.
