*Average speeds are based on the download speeds of at least 50% of customers at peak time (8pm to 10pm). Speed can be affected by a range of technical and environmental factors. The speed you receive where you live may be lower than that listed above. You can check the estimated speed to your property prior to purchasing.
Fibre/cable services at your postcode are subject to availability. You can confirm availability on the provider's website.
Some broadband providers may increase monthly prices each year during your contract. Please refer to individual broadband provider's terms and conditions before signing up.
Broadband deals in Cardiff
If you’re living in the Welsh capital, you’re in luck – Cardiff gets great coverage from all the major broadband providers. Plus, you can enjoy some of the speediest internet available in Wales.
Of course, speeds and availability can vary, depending on where exactly in Cardiff you live. Nevertheless, you should be able to easily get a superfast broadband deal with speeds between 36-68Mbps, at minimum.
You’ll be able to shop around and compare broadband packages from a wide range of providers.
What types of broadband can I get in Cardiff?
Thanks to Cardiff’s excellent coverage, you’ll be able to get all types of broadband. Plus, you’ll have your pick of provider.
While all homes should be able to get standard ADSL broadband, you may be happier with fibre optic broadband instead. As it uses fibre optic cables, it’s much faster and more reliable than ADSL. Not to mention, Cardiff has great fibre optic availability.
The most common fibre optic connection is fibre-to-the-cabinet (FTTC). This uses fibre optic cables to connect the exchange to the nearest street cabinet to your home, before using copper phone wires between the cabinet and your home. Average speeds are usually between 36-68Mbps, which is a good speed for most households.
On the other hand, fibre-to-the-premises (FTTP) uses fibre cabling all the way between the exchange and your home, which means a much quicker, more stable connection. Speeds could be anywhere from 100Mbps to over 1,000Mbps.
Visit our page on FTTP and FTTC broadband to learn more about these two types of fibre broadband.
Finally, there’s also cable broadband, which uses both fibre optic and coaxial cables to provide ultrafast gigabit broadband. Virgin Media provides the most widely available cable network in Cardiff at the moment.
Getting fibre broadband in Cardiff?
Virtually all homes in Cardiff should be able to get fibre optic broadband from a range of providers, including the likes of BT, Sky, EE, NOW Broadband, Plusnet, TalkTalk and Vodafone.
The speed of your connection may vary, though, depending on what you can get. Most homes should be able to get superfast fibre with average speeds between 36-68Mbps, which is widely available across Wales.
Compared to the rest of the country, Cardiff has much better access to ultrafast speeds. You may be able to get an ultrafast full fibre package, or Virgin Media’s gigabit-ready cable broadband.
How to get a better broadband deal
Whether you're looking for cheap and cheerful or high-spec full fibre broadband, everyone's needs are different. Finding the best deal for you starts with understanding how you plan to use it or if bundling your services lower your monthly bill.
-
Are you still within your contract?
If you're still in your minimum term, you'd be subject to an early repayment charge if you ended your contract early.
If you're out of contract or approaching the end, you can switch without penality.
-
Can you get a better deal for the same price?
A tariff may offer everything you're looking for, but does it come to the right monthly price and offer good value for money? Shop around to find the right tariff at the best possible price.
-
Can you get any bundles, freebies, or cashback?
Many providers offer tempting incentives, such as cashback or gift cards to new customers. These may help bring down the cost of an expensive broadband deal, although you should also consider whether these gifts are as important as factors such as speed and cost.
How to compare and switch broadband
There are three simple steps to compare broadband deals and switch providers
-
Check you're out of contract
Ensure you're no longer within the minimum terms of the contract length with your current broadband provider. You can find out by looking at your original contract, confirmation email, or by contacting their customer service.
-
Enter your postcode and choose a personalised bundle
We algorithmically sort broadband packages based on your location, the speed you'd get, and how much it costs.
-
Complete your switch
Your new provider should contact your current provider and arrange the switch for you. And you'll receive letters and emails updating you on this.

Broadband explained
Which is the best internet provider in Cardiff?
The best broadband provider in Cardiff largely depends on what you’re looking for in a broadband deal – as well as what’s actually available at your address.
If you’re after the fastest possible broadband, Virgin Media may be the best option. The fastest widely-available broadband provider in the UK, it offers speeds up to 1,130Mbps – and living in Cardiff, it’s likely that you’ll be able to get those top speeds.
What broadband speed can I expect in Cardiff?
That depends on the package you choose, as well as your exact address. While Cardiff has great broadband availability, speeds can vary throughout the area depending on where you live.
Want to check the speed you’re currently getting? Use our broadband speed test to see your home broadband speed – that way, you can check if you’re getting the advertised speeds, and decide whether you need a faster broadband package.
