But a quarter of those households who are already able to connect still have not done so.
The fibre roll-out is due to be completed by the end of next year, replacing the previous copper connections and enabling superfast broadband.
Once the work is complete, all copper connections will be switched off.
Cyrille Joffre has been leading the fibre rollout for Sure.
‘Just over 20,600 properties are now connected to fibre, so just under 6,500 who are on copper still need to connect to fibre,’ he said.
‘Of this figure, more than 5,300 can connect today through their chosen service provider.’
Fibre is now available across all parishes.
The final 1,300 homes still needing to be hooked up are likely to be the more complex or unusual cases faced by Sure, which may require careful planning of the installation.
Once a connection is made, islanders need to arrange for an engineer’s visit for the installation of the new optical network terminal.
‘In areas where fibre has been available for around a year, 81% of customers have requested to be connected – which is a take-up rate well ahead of other
jurisdictions including the UK,’ said Mr Joffre.
The copper network switch-off begins this month and will continue in stages throughout 2026. Anyone who wants a landline or broadband service will need to switch to fibre to keep connected to internet.
All landlines will also be changing to fibre by the end of 2026.
‘Many of those who have yet to switch only have a landline service,’ said Mr Joffre.
‘Some customers may think that fibre is only required for broadband, and as we are switching off the copper infrastructure we also need to move telephone services from copper to fibre.’
Sure has been ensuring that homeowners are informed.
Those who have not yet switched to fibre in an area where the copper network is due to be switched off will receive up to three visits followed by three letters, with the last being hand-delivered.
Guernsey Fibre reflects a £37.5m. investment in a full-fibre broadband network.
The project launched in 2022 and is being carried out by Sure, in partnership with the States, which is providing part-funding of up to £12.5m.
Guernsey Fibre offers speeds up to two gigabits per second.
UK Ofcom’s Connecting Nations report update from the start of this year noted that 86% of UK homes had gigabit-capable broadband and nearly three-quarters of UK homes can access a full-fibre broadband service.
This equates to 22.5m. homes. But only 9m. have chosen to have full-fibre broadband connections.
The UK is also planning to retire its copper network eventually, but that work is expected to stretch into the 2030s.
