All you need to know about Guernsey Fibre

Guernsey Fibre is a project by Sure that will deliver high-speed fibre broadband to homes and businesses in every parish over the next five years. 



Why does Guernsey need fibre?

All of our lives are becoming increasingly digital and internet services are more vital than ever so it’s essential that network performance and connection speeds are able to deal with our island’s future demand.  Guernsey Fibre is going to cover the whole island with superfast broadband, bringing the possibility of true 1 gigabit-per-second coverage to all meaning that meaning multiple users in the same house can play games online, shop, download films, work, stay in touch with friends and listen to music all at the same time.

How does a fibre broadband network enhance Guernsey’s economy?

Guernsey Fibre is a crucial project that will help boost the island’s economic and social prospects, and one we are hugely proud to deliver.  The fibre broadband rollout is a massive engineering project, and we will use local suppliers wherever possible, meaning millions of pounds spent with Guernsey businesses and the creation of around 75 jobs. It will allow digital businesses to thrive and have the flexibility to be based anywhere on the island, expanding economic possibilities and fostering creativity and entrepreneurialism. The uplift in productivity from the ability to work seamlessly from anywhere is expected to provide a 1.1% boost to the economy, all thanks to Guernsey Fibre.*

What is the States of Guernsey role in the project ?

Guernsey Fibre represents an investment of £37.5m. This Sure project is being carried out in partnership with the States of Guernsey who are providing a capped investment of up to £12.5m. The States of Guernsey’s investment will enable Sure to accelerate the programme and to ensure that that there is fibre for everyone within the timeframe

What are the benefits of fibre?

A full fibre to the home connection will be faster, more stable and more reliable than a mixed fibre and copper network (which we have at the moment).

Fibre connectivity ensures that networking speeds are maintained from the internet all the way to your premises with no loss of performance. It also increases capacity, so your connection can run multiple devices and online services at the same time, with no drop in performance.

What is fibre?

‘Fibre’ is shorthand for fibre optic cabling. A fibre optic cable consists of tiny tubes, each tube as thick as a human hair.

They are reflective on the inside and transfer information by sending flashes of light that is interpreted as data. It’s much more reliable and very quick compared to other technologies such as copper.

Removing copper cabling and providing end-to-end fibre connectivity ensures consistency of performance and enables services to be introduced and expanded without the need for any physical upgrades to the fibre that connects to your household or business premises.

What is the difference between fibre and 5G?

5G is a mobile technology that involves signals being transmitted from antenna to antenna to provide a mobile network. Fibre is a wired connection that runs from our central exchange to

your home. Both are next-generation technologies that will provide faster speeds and more reliable connections.

Is fibre eco friendly?

Fibre is a more sustainable option. The amount of energy needed to send light through a fibre optic cable is considerably less than what is needed to transmit an electrical signal through copper cables, so there will also be emissions savings. This project will make Sure’s broadband both more efficient and more environmentally friendly.  

How long will this roll out take?

Rolling out fibre broadband around the island is a huge and exciting undertaking. The project will commence in 2022, when Sure will begin connecting properties and the roll out is targeted for completion by the end of 2026.

Who will I need to sign up with if I want to switch to fibre?

Sure is installing the fibre broadband network, futureproofing Guernsey’s telecoms infrastructure for decades to come. Much like the current broadband network Sure’s new fibre network will also be available to other service providers on a fair and equitable basis, meaning you will still have choice when it comes to connecting with fibre.

The Commercial Pilot Phase

How will I know if my property has been identified as part of the pilot phase

If your property has been identified as part of the commercial pilot your retail service provider will contact you directly to see if your eligible to take part. 

What is the eligibility criteria for the commercial pilot

During the commercial pilot phase Guernsey Fibre landline services will not operate in a power cut.  If any of the below are relevant to you will not be eligible for the pilot 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. 

Even 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.
