BT Group has reassured investors that it is still on course to generate roughly £2 billion in free cash flow this financial year, thanks to stronger-than-expected demand for its full-fiber broadband network. The UK telecom giant said its Openreach division has now passed 10 million premises with full-fiber connections and achieved a record 41% take-up rate — the proportion of homes and businesses offered the service that actually sign up.
The update comes as BT ploughs billions into upgrading its network, a strategy that hinges on convincing customers to switch from older copper-based lines to the new fiber infrastructure. For investors, the key question has always been whether that heavy spending will eventually translate into durable cash generation. Today's numbers suggest the answer is moving in the right direction.
What the numbers show
BT said revenue and profit measures for the quarter came in slightly ahead of expectations, though it continued to lose broadband lines. The company reported a loss of 175,000 lines in the quarter and expects around 800,000 losses for the full year, as competition from rivals like Virgin Media O2 and smaller players remains intense.
Despite those line losses, BT reiterated its plan to reach 25 million premises with full-fiber by March and kept its longer-term target of around £3 billion in annual free cash flow by the end of the decade. The company's ability to hold its cash guidance while still expanding coverage is a sign that the economics of fiber are improving.
One factor that could help BT is the recent pullback by some competitors. Reuters noted that Virgin Media O2 is scaling back some of its fiber ambitions as part of a cost-saving drive. If rivals slow their buildouts, that could ease pricing pressure over time and give BT more room to win customers on its own terms.
Why the take-up rate matters
Fiber rollouts are expensive upfront. The digging, cabling, and equipment are largely fixed costs, meaning the real payoff comes only when households actually subscribe. So while the 10 million-connection milestone is a notable achievement, what matters more is what it signals about utilization.
Each additional customer tends to add more revenue than cost once the network is in place. That means cash generation can improve even while coverage is still expanding toward the 25 million target. The record 41% take-up rate suggests BT is converting its investment into paying subscribers more efficiently than many investors had feared.
This dynamic makes BT's near-term cash goal look more credible and can reduce how much the stock swings on quarterly noise like line losses. Indeed, the shares have outpaced the FTSE 100 this year, a sign that the market is beginning to reward the company's progress.
What it means for investors
For everyday investors, the key takeaway is that BT's fiber strategy is showing tangible signs of working. The company is spending heavily, but the take-up rate is climbing, which is the metric that ultimately drives cash flow. The £2 billion free cash flow target for this year is a critical near-term checkpoint, and today's update suggests BT is on track to hit it.
That said, the broadband line losses are a reminder that competition remains fierce. BT is still losing customers overall, even as it wins more fiber subscribers. The question is whether the fiber gains will eventually offset those losses and lead to sustainable growth.
Investors should also keep an eye on the broader competitive landscape. If rivals like Virgin Media O2 continue to pull back on fiber expansion, BT could face less pricing pressure and find it easier to hold onto customers. That would be a positive for the company's long-term cash generation.
For now, the market seems to be taking the update in stride, with the stock's outperformance this year reflecting growing confidence in BT's turnaround story. As always, no single quarter tells the whole tale, but the direction of travel is encouraging.
