BT losing 800k customers: what it means for your broadband bills

BT is facing a significant customer exodus, with plans to lose around 800,000 customers as the telecoms giant reshapes its business around fibre broadband. If you’re a BT customer, here’s what you need to know and whether this affects your bills or service.

BT, one of the UK’s largest broadband and phone providers, reported flat sales of £4.3bn in the first quarter, with profits falling. The company is deliberately shedding older, less profitable customers on its copper-based network as it focuses investment on faster full-fibre broadband instead. This shift is part of BT’s long-term turnaround plan to stay competitive.

The good news is that BT says full-fibre broadband now generates more than half of its broadband revenue, and demand is growing. For customers upgrading to fibre, this typically means faster speeds and more reliable connections — though potentially at a higher price point.

If you’re on BT’s older copper network and haven’t yet switched to fibre, now’s the time to act. You may receive offers to upgrade, or you might be encouraged to move to another provider. Don’t panic — this isn’t sudden. BT is managing the transition gradually, and you’ll have notice before any service changes.

What should you do? First, check if full-fibre is available at your address (search BT.com or use Ofcom’s broadband checker). If you’re happy with BT’s fibre offering and it’s available, upgrading could lock in your service and potentially give you better speeds. If you’re looking to switch providers, now is actually a competitive time — other networks like Virgin Media O2, Sky, and Plusnet are all actively competing for customers.

Compare deals carefully using comparison sites, and check what speeds you actually need. Most households are fine with 50–100 Mbps; if you work from home or have heavy users, aim higher.

Keep an eye on your BT bill over the coming months. If you receive a notice about network changes or service upgrades, read it carefully and respond to any deadlines. Don’t ignore letters about your broadband — they often contain important information about what happens next.
