If you shared information on how much you pay for your broadband, your results will highlight deals with an annual saving of £5 or more. Annual savings show what you could save in the first 12 months. Your savings are the difference between the annual cost you entered for your current deal and the deal you could switch to. The annual savings amount does not include:
  • setup costs or one-off payments
  • vouchers, bill credit or other goods
  • annual price increases

*The "average" speed displayed in Mb represents the speed available to 50% of customers with this product during peak time (between 8pm and 10pm). The actual speed you will get depends on your cabling, your area and (with non-fibre optic products) time of day and how far you are from the telephone exchange. Most providers will tell you the likely speed you will receive when you begin your online sign up — this may differ from the average speed displayed on our table.

The deals available at your postcode are subject to local availability. The provider will confirm availability for your line.

We aim to take the strain out of broadband comparison. Good broadband deals aren't just about the price, it's also about what's included in the product, the speeds offered and any extra incentives providers are offering. To balance all of these, we have developed a ranking formula that takes into account deals that are proving to be popular with our customers, that are competitive in the market and have a smooth buying process.

If you prefer, you can sort deals by monthly cost, speed or contract length. You can also choose to show costs as monthly or full contract, which lets you see the total spend over the contract period, including any setup costs.

Uswitch services are provided at no cost to you, but we may receive a commission from the companies we refer you to.

How good is the internet in Cardiff?

Cardiff is very well covered by high-speed broadband services, and is home to some of the fastest average services in Wales.

The fastest widely available speeds are from Virgin Media, which offers packages of up to 1.1Gbps through its dedicated cable network — though this may not be available to everyone. But much of Cardiff can also access ultrafast full fibre deals, which are now available to one third of UK properties and offer speeds in excess of 1Gbps.

The speeds available may vary throughout Cardiff, so it pays to check what's available to your home. Our speed test tool can show you the speeds you can expect to receive at your home.

What is the best Wi-Fi in Cardiff?

Like most UK cities, the exact performance you can expect from wireless internet in Cardiff will depend on where you live, and the speed of services can vary even from street to street.

In general, however, almost all residences can expect speeds up to 67Mbps, half can access Virgin Media's ultrafast deals, and a third of premises can get full fibre.

How to find broadband deals in Cardiff

The best deal for you will depend on a number of factors. As well as the price per month, you should consider the speed you can expect to receive and whether this will be enough for your expected usage, as well as the performance of Wi-Fi routers and what extra features are included, such as parental controls and antivirus software.

With so many broadband providers in Cardiff, it can be tricky to know what the best deal for you is. However, you can use the Uswitch broadband postcode checker to easily find out exactly which providers and packages are available at your home.

Does Cardiff have full fibre broadband?

Yes, there are several locations within Cardiff where consumers can access full fibre broadband, or fibre-to-the-premises (FTTP) as it's also known, with around 33% of the country covered at the time of Ofcom's most recent Connected Nations report.

This technology uses fibre optic cabling all the way to your home, as opposed to most standard fibre services, which still use copper for the last part of the journey. Full fibre results in speeds that can be up to 20 times faster than other alternatives.

Cardiff was one of the first nine cities in the UK to benefit from Openreach's Fibre First programme. Work is in progress to bring this technology to the city centre, while some nearby locations have already seen the work completed.

What are the full fibre broadband providers in Cardiff?

In addition to providers using Openreach's network, there are several other providers offering full fibre broadband in Cardiff. For example, city-focused firm Hyperoptic runs FTTP services to dozens of buildings in the city centre, most of which are large, modern apartment blocks.
