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The 12-month limit is obsolete if you haven’t presented accurate or regular meter readings to your energy supplier during the time you’ve been a customer, or if you’ve blocked a meter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.
