Why should I move to Fibre Broadband?
Fibre Broadband is delivered in a much more modern way using cables that are a lot less susceptible to interference or the elements, and enables much faster speeds than traditional cables, some of which have been in the ground for over 70 years.
What speeds are available with Fibre Broadband?
Since 2014, we have offered Fibre Broadband speeds of up to 1Gb (1,000Mb) on our own Fibre network and continue to offer a minimum speed of 500Mb for any customers. For any customers not on our own Fibre network, we will be providing a slight increase in your existing speed at no additional cost, when you are upgraded.
How much will it cost to move to Fibre Broadband?
If you’re in a Fibre-enabled area, there is no difference in monthly cost to our existing non-Fibre Broadband plans.
When will I be able to get Fibre Broadband?
The roll-out began in April 2022 and is expected to be completed in 2026.
More information on what areas will be enabled first and island-wide target dates will be provided nearer to the launch date.
What do you need to do to enable Fibre Broadband in my home?
We’ll need to install a new Fibre box where your existing Broadband service is connected, which will require a small amount of new cabling to be installed. We will discuss this before commencing any work. We’ll also supply you with a new router that is capable of running at these new speeds.
What do I need to do to make the most of Fibre Broadband in my home?
We recommend you add JT Total Wi-Fi to your Broadband package, if you don’t already have it. JT Total Wi-Fi will ensure that you have the best possible Wi-Fi coverage within your home.
What do I need to do next?
If you sign-up to our Fibre Broadband newsletter, we’ll provide sign-up information as soon as it becomes available.
What happens when I’ve requested to move from copper to fibre?
Once you have completed your order, you will be contacted within a few days to arrange a pre-installation visit, this is to ensure there are no unexpected complications when the service is installed. Upon completion of the pre-installation visit, the engineer will arrange a convenient date to install the service.
What happens if there is a power cut?
Fibre landlines, Lifeline health alarms and broadband services will not operate during a power cut unless battery back-up equipment provided by Guernsey Fibre has been installed in your home. Without a battery back-up unit being in place during a power cut, you would not be able to call the emergency services from your landline. Mobile services would be unaffected for as long as operationally possible. You should also be aware that regardless of whether your landline is provided via the traditional copper network or via the new Guernsey Fibre network, any cordless telephones (‘DECT’ units, not mobile phones) will not operate during a power cut. Should you be reliant on your landline, please ensure that you have at least one corded telephone connected to your landline.
If you order a fibre service, a Guernsey Fibre engineer will undertake a pre-installation visit to your premises. During that visit they will ask you to complete a short checklist, the results of which will indicate whether you are entitled to a free battery-back up unit. The checklist will include the following topics:
- Whether any household is appreciably more likely to require the emergency services, including anyone who has a Lifeline health alarm;
- Whether any householder or a household member has a medical condition/disability that could present severe consequences if they could not contact the emergency services;
- Whether a householder lives alone AND has limited mobility or a visual or mental impairment that could hamper their ability to seek help in a emergency;
- Whether there is no mobile signal within the premises, or whether any householder or household member is not readily able to use a mobile phone.
Once you have completed the short checklist, the engineer will be able to tell you whether you qualify for a free battery back-up unit. You are not required to have one installed, if you would prefer not to.
A battery back-up unit is available to all other customers, but on a chargeable basis. If a unit is installed at the same time as your fibre service, the charge is £26.85. Should the engineer need to undertake a specific visit (i.e. after your fibre service has been installed), the charge is £59.35. If you would like one, just let the Guernsey Fibre engineer know when they visit you.
All battery back-up units have an estimated lifespan of six years and apart from periodic testing by a householder (ideally monthly; instructions provided), no maintenance should be required. In case of any issues with a battery back-up unit provided by Guernsey Fibre, please call them on 700900 (during normal hours).
Fibre is now ready to be connected at most homes* in the following postcodes.

* One Gigabit Fibre: 1,001Mbps average speed achieved using an Ookla Speed test app built into a router. Test conducted in August 2021. JT’s standard 1Gbps router can provide an average speed of around 950 Mbps, but for a full 1Gbps service you would need to use a router capable of speeds in excess of 1Gbps (e.g. a 2.5Gbps model).
