Is fibre broadband available across all of NI?

Yes, it’s possible to get a fibre broadband connection in Northern Ireland, although it’s skewed toward urban areas. According to Ofcom, just 36% of rural areas have access to full-fibre broadband, compared to 85% of urban areas. Virgin Media and BT dominate the market and are available in and around the country’s largest towns and cities, including Belfast, Londonderry, Coleraine & Ballymena.

But, fibre is still being rolled out across the country and new areas are getting connected all the time.

If you want to find out what’s available near you, use our postcode checker at the top of the page. Once the results have loaded, sort by ‘download speed’ at the top of the deals.

Should I consider cheap broadband?

ISPs including Plusnet are some of the cheapest in Northern Ireland, with deals starting from £25 per month.

Choosing a deal that’s right for you, however, should never be done based on price alone. Make sure you’re paying for the right internet speed to suit the number of people in your household and the things they enjoy doing online regularly - otherwise the savings you make could be a false economy.

Also try to look for packages that bundle broadband alongside other services (TV or phone), as they can save you significant costs in the long run.

Finding the best cheap broadband deals in Northern Ireland is easier with our free postcode checker. We’ll show you a complete list of all of the broadband deals and special offers that you can choose from where you live. You can compare the full list, or narrow down deals based on the criteria you select.

If you’re not sure what broadband speed you need, our guide can help you make a choice depending on a number of variables.

Is mobile broadband a good alternative?

Mobile broadband may be your best option to access the internet at home in some parts of Northern Ireland, especially in rural areas that may not have access to a phone line or fibre broadband.

Mobile broadband uses the mobile network and reception varies, depending on what area you’re in. If there’s no coverage, mobile broadband won’t be an option either.
