YouFibre has connected its 100,000th customer, doubling its base in the last nine months.
WightFibre has now passed 70,000 homes and has connected 21,000 customers to its network, representing 80% coverage and 30% of the market share.
This has been fuelled by £3.1m in BDUK Gigabit Broadband Vouchers claimed to date.
Looking ahead the altnet remains on track to achieve 90% coverage on the island by the end of 2025, and 98% Coverage by 2027.
John Irvine, CEO of WightFibre, said: “Our secret sauce is localness, we’re rapidly becoming woven into the very fabric of the Isle of Wight.”
