Fibre is coming to Guernsey

Guernsey Fibre is a five-year project by Sure with a target completion of the end of 2026 to connect every home in Guernsey directly to our fibre broadband network.   

Our team of specialist engineers will be working their way around the island connecting homes the network and we will be connecting more than 30,000 individual households to the network. 

To plan the roll out, we’re considering the infrastructure that’s already in place, the density of the households, the ease of access to infrastructure and the disruption any work will cause. 

Sure has been trialling fibre broadband connectivity for the last couple of years and these trials have delivered fantastic results so we’re very excited to deliver fibre connections island-wide. 

The Guernsey Fibre project will provide fast, stable, reliable connections into every property and facilitate working from home, high-end gaming, top-quality streaming and multi-device households.  



Commercial pilot phase

We are currently in the commercial pilot stage of the project which means we are currently installing fibre into a small number of homes.  If your property has been identified as eligible to join the pilot your retail service provider will contact you directly to see if you wish to participate. 

Please note that during this commercial pilot phase Guernsey Fibre landline services will not operate in a power cut so some customers in fibre-enabled areas may not be suitable to upgrade to a fibre service during this phase. 

If any of the below are relevant to your property you will not be eligible for the pilot phase and will need to wait until the full service has been launched:

  • You or someone in your household has a higher than normal likelihood of needing to contact the emergency services (999 or 112) .
  • You do not have a mobile phone signal inside your home.
  • Your landline is used to remotely monitor an alarm system (e.g. burglar, fire, lift or Lifeline Care).

The full Guernsey Fibre service is currently expected to launch around April 2022 and will include battery back-up options, to ensure that those customers who need to or wish to maintain a landline calling facility during a power cut will be able to do so. Details of the battery back-up options will be made available nearer the time.   If you are eligible and your retail service provider encourages you to upgrade to fibre during this pilot phase, you are under no obligation to do so.

Progress on the project will be posted here so please check back regularly for updates
