Broadband, TV, mobile and home phone companies will have to tell customers when their contract is coming to an end. That’s according to new rules announced by communications watchdog Ofcom today.

It’s believed this latest addition to Ofcom’s Fairness for Customers Programme could benefit around 20 million customers who have long passed their initial contract period. The changes won’t come into effect until 12 February 2020, though, so anyone already out of contract will still have to check manually until this date.

When the changes do come into effect, providers will be required to send both private and business customers information about their current contract, as well as notifications on the best deals available. This will be anywhere between ten and 40 days before the contract period ends.

The alerts, which will be sent by text, email or letter, will have to include:

• The end date of the contract
• The price paid before this date
• Any changes to the service and price paid at the end of this period
• Information about notice periods needed to before they can end a contract
• Best provider deals on offer, including letting long-term customers know what prices are available to new customers

Those who decided to stay in their current contract will also be sent a reminder about the firm’s best deals every year. It’s hoped that the changes will enable customers to shop around more effectively and choose the best package to suit their needs.

Lindsey Fussell, Ofcom’s consumer group director, has said the change “will put power in the hands of millions of people who’re paying more than necessary”.

While this is definitely a win for customers, providers will not be required to tell people about offers from rivals, so this new rule might not necessarily get you the best deal. It will give you a heads up, though, and that’ll give you time to check out contract options from other providers.

According to the communications watchdog, approximately 14% of people have no idea whether or not they’re still in a contract, while 12% believe they’re in a contract but don’t know when this period comes to an end.

If you want to check a contract now but don’t have the original paperwork, you can call your provider for full details, including a contract end date and their latest deals.
