As broadband upgrades are rolled out across the country, you may find that Fibre or Ultra Fibre packages are available in your area. This is why you are asked to provide your postcode when comparing broadband providers.
Upgrades to broadband services are carried out in largely populated areas first and will eventually roll out to more rural areas.
In more rural situations, you may find it better to consider a mobile broadband package which is supplied via a dongle and uses 3G/4G mobile networks. Speeds on 4G networks are still very fast and providers are starting to offer unlimited data packages.
In the most rural of areas your only option may be satellite broadband, delivered to you via a satellite on the side of your house.
When using the comparison system you will be shown all providers that have a service available in your area along with the various connection types available to you.
