    It can be a surprise when your business energy bill suddenly increases in price and you can’t work out why. Is it because of a hike in energy prices or has your bill simply been backdated?

    Backdated energy bills can be quite common for people who pay based on their estimated usage rather than their meter readings.

    Check out how to ensure you’re being billed accurately and everything you need to know about energy back-billing.

    What is back billing?

    To backdate a document means to date it in the past or prior to what it should be. Generally, the practice is inadvisable and can even be illegal in the case of certain documents. However, there may be some circumstance when backdating is acceptable.

    Sometimes, a document needs to be backdated in order to make it accurate. For example, in the case of a business contract, a company might have completed work prior to signing a contract with a client and therefore the contract can be backdated to reflect when that work began. As long as both parties are in agreement and there is a clear commencement clause in the contract, this is fine.

    Backdating, however, may be illegal under the Theft Act 1968. Section 17, named ‘False Accounting’ states that a person could be liable to imprisonment for up to seven years if they provide false information on a record or document for their own gain. This would include backdating a document if it meant they would gain something from it.

    For example, a person missed their car insurance payment on the 1st of March and was involved in an accident on the 14th of March. They backdated the cheque for when their car insurance was due and sent it to their insurance company. The person wasn’t insured for the accident on the 14th because they’d missed a payment. They then backdated the cheque so that the company would have to cover the damage caused to the vehicle. This is when backdating is illegal.

    How long can energy bills be backdated?

    If you do owe money to your energy supplier and you notice that your bill has been backdated, it’s worth noting that you only need to pay for the energy you’ve used in the last 12 months. A bill cannot be backdated longer than 12 months due to a new regulation that was introduced by Ofgem in April 2018.

    This prevents businesses from owing thousands of pounds to an energy supplier if they’ve been underpaying for a number of years.

    Therefore, if you notice that your energy bill has unexpectedly increased in price, you should find out how long the bill has been backdated as it could be that it stretches longer than this 12 month duration.

    It’s also important to make sure that you’re not overpaying on what’s owed. You can do this by checking the meter readings on the oldest bill from this 12 month period and compare it against the readings on your newest bill. Then, check your energy meters to see the usage on there. The figure on the energy meter should match the figure on your bill. If it does, then you’ll need to pay for what you’ve used. If it doesn’t match, you should get in touch with your supplier to discuss the issue.

    The 12-month limit is obsolete if you haven’t presented accurate or regular meter readings to your energy supplier during the time you’ve been a customer, or if you’ve blocked a meter reading from taking place. In this case, a backdated bill could stretch longer than 12 months. This is why it’s imperative that you stay on top of your readings.

    A backdated payment isn’t generally due in one go – the supplier will normally spread it out over a further 12 months, so your monthly payments will increase during this time.

    Who is my energy supplier?

    If you haven’t been receiving your energy bills and you are not sure who your gas and electricity supplier is, don’t worry. Check out our guide on finding out who your supplier is. You can use the Meter Point Administration’s online search tool, to find out who supplies your gas. Also, you can find your electricity supplier using the Energy Networks Association postcode search tool.
