If you’ve been a BT customer for a while and your contract is coming to an end, you might be wondering whether you should switch or stay on. If you want to stick with BT, you can take some steps to get a better deal.

  • If you’ve been a BT customer for a while and your contract is coming to an end, it’s a good time to review your options.

  • You may be able to get a better deal by upgrading with BT, adding services or negotiating a new price.

  • It’s also worth comparing the deals available from other providers before you decide.

Add an EE SIM-only deal to your existing package

If you have BT broadband, you may be eligible for exclusive EE mobile and SIM-only offers. BT broadband customers can currently get money off selected EE data plans, and some handset offers include extra data.

EE offers both 24-month SIM-only contracts and flexible 30-day rolling plans. Before adding a SIM, compare the total cost with other mobile providers and check that the data allowance suits your needs.

Add EE TV to your existing package

You could consider adding EE TV to your BT broadband package if you want to combine your home entertainment and broadband bills.

EE TV’s current packages include Entertainment, Entertainment Plus, Sport, Sport Plus and Full Works. Depending on the package, you may get access to services such as NOW Entertainment, NOW Sports, NOW Cinema, TNT Sports and Netflix.

If you take a flexible EE TV package, you can change your TV package once a month during your minimum term. Bear in mind that adding EE TV generally means taking a new or renewed BT broadband contract, and delivery or activation charges may apply.

Upgrade your BT package if your broadband speed is slow

If your connection is slower than your household needs, upgrading to a faster package could help. The right speed depends on how many people and devices use your broadband at once, and whether you regularly stream, game, work from home or make video calls.

BT offers a mix of part-fibre and full-fibre packages, depending on availability at your address. If full fibre is available, you may be able to choose a faster package with download speeds better suited to busy households.

You could also consider BT Complete Wi-Fi. This includes a Wi-Fi extender, with up to two additional extenders available where needed to help improve signal around the home. It is designed to improve in-home Wi-Fi coverage, rather than the speed reaching your property.

Lower your bills by reviewing your call plan

If you still use a home phone, check whether your calling plan matches how often you make calls. BT offers different options, including pay-as-you-go, 700-minute and unlimited-call plans.

Moving to a cheaper plan could save money if you make few calls. If you make regular calls abroad or need features such as Caller Display, you may be able to add these separately.

BT existing customer deals: should you switch or upgrade?

When it comes to broadband, it often pays to shop around at the end of your contract. New-customer deals can be competitive, and switching provider may give you access to lower prices, faster speeds or rewards that are not available when you stay put.

That said, upgrading with BT may be convenient if you are happy with the service and can secure a competitive price. Compare your options first, then decide whether to switch or negotiate a new BT deal.

Tips for finding BT upgrade deals

If you’d prefer to stay with BT, these steps could help you get better value.

Call BT to negotiate a deal

Contact BT when you are out of contract or nearing the end of your minimum term. Check comparable deals from other providers first, then ask whether BT can match the price or offer a discount, bill credit or useful extra.

You are usually in a stronger position to negotiate once your minimum term has ended, as you can switch without paying an early termination charge.

Raise a service problem

If you are having problems with your broadband, TV or home phone service, contact BT to explain what is happening. It may be able to troubleshoot the issue, arrange an engineer visit or discuss the support available to you.

If poor Wi-Fi coverage is the problem, ask whether BT Complete Wi-Fi or additional extenders could help. These are subject to your package and eligibility.

Bundle your broadband with extra services

Adding EE TV or an EE mobile plan to your BT broadband could make managing your household bills simpler and may unlock customer offers.

However, a bundle is not automatically the cheapest option. Compare the total monthly cost, any upfront charges and the length of each contract before you commit.

Look for BT Shop promotions

BT broadband customers can also check the BT Shop for promotions on technology and connected-home products. Compare prices elsewhere before buying to make sure the offer represents a genuine saving.
