Fibre FAQs


Installing fibre broadband needs a Sure engineer to visit your home to talk through the best options for the equipment you need. If you'd like your equipment in a specific room, this may cost extra* if more cabling is required. If you are renting, please make sure you have the homeowner's permission before your installation. 

Orders are completed by email after an engineer visit. Please read these confirmation emails carefully, and remember they may go into your junk or spam folder.

What our customers say

"These faster speeds are great. My daughter ran downstairs to tell us she had downloaded the new Bond in 1 minute 12 seconds, compared to 40 minutes! The installation process wasn’t disruptive at all. The engineers were fantastic, explaining the technology and answering all our questions."

Great for working from home 

Watch what small business owner Ian Dodsworth says about how his 100Mb Fibre broadband package improved browsing speeds and his experience of working from home. 

  • All speeds shown are average.

  • Sure’s is the only Channel Islands network capable of full 1Gbps average speeds. Other Channel Islands operator’s networks cannot achieve average speeds above 950Mbps. 

  • One Gigabit Fibre: 1,001Mbps average speed is attainable using Ookla Speed test app built into the router. Test conducted in August 2021. To achieve speeds of 1001 Mbps (1Gbps) or higher you will need to use a router capable of speeds greater than 1Gbps (eg a 2.5Gbps router) to receive that speed as the average. Your service will still work with a 1Gbps router, but your average speed will be around 950 Mbps.

  • There is no connection charge to switch to fibre broadband. Your monthly charge depends on which Sure Fibre Broadband and Home Gateway (Router) you choose. Home Gateway (Router) charges over 24 months are: Basic: £3.50 per month, Standard WiFi 6: £4.50 per month. Router charges automatically stop after 24 months.

  • Prices include Sure Home phone (landline).

  • *Charges for non-standard installation are £32.50 per half hour, plus cost of materials, which will be defined at the time of survey by our engineer and communicated to you.
