Openreach has hailed its successes in achieving many of Ofcom's Minimum Service Level (MSL) targets.
According to Kevin Murphy, Managing Director for Business and Corporate Delivery, the Mean Time to Provide (MTTP) - effectively the average speed of delivery - is 40 per cent faster than it was two years ago.
Speaking to ISPreview.co.uk, he said that in 2016, Openreach was probably "among the worst in Europe" when it came to MTTP.
However, he said Openreach is now "genuinely world-class", as he is not aware of any other operator in the world that is delivering "point-to-point fibre for businesses as quickly as we are".
Mr Murphy also noted that great progress has been made on the Lower Percentile MSL - the percentage of circuits that it delivers within six weeks.
Furthermore, he said the percentage of faults that it fixes within five hours, 24 hours a day, 365 days a year, has also improved, passing the 95 per cent mark.
"If you think of what that really means, it's pretty astonishing," Mr Murphy commented.
"It means if something breaks in the middle of nowhere in rural Wales at 3am on a Sunday morning, there’s a 95 per cent chance of us fixing that problem in five hours. It’s an incredible feat of engineering."
Mr Murphy went on to note that both its customers and Ofcom have said they have noticed recent improvements.
However, he stressed that Openreach is "not stopping there", and still wants to do "a lot more" to make services for its customers even better.
