UK Broadband Speed Guide

Understanding Broadband Types

Not all broadband connections are equal. The type of connection running to your property determines your maximum possible speed, and no amount of router upgrades will overcome the limitations of your physical line.

ADSL uses your existing copper telephone line and delivers speeds up to around 11 Mbps download. It is the slowest option still available and is gradually being phased out as fibre networks expand. If your home still relies on ADSL, upgrading should be a priority.

FTTC (Fibre to the Cabinet) runs fibre optic cable to the green street cabinet, then uses copper for the final stretch to your home. Typical speeds range from 30 to 80 Mbps. This is the most common connection type in the UK and is adequate for households with moderate usage. The further your property sits from the cabinet, the slower your speed will be.

FTTP (Fibre to the Premises) delivers fibre optic cable directly into your home, removing the copper bottleneck entirely. Speeds range from 100 Mbps to over 1 Gbps depending on the package. FTTP is the gold standard and is being rolled out rapidly by Openreach, CityFibre, and alternative networks. Check availability at your postcode before assuming it is not an option.

Cable (Virgin Media) uses a coaxial cable network separate from the Openreach telephone infrastructure. Speeds reach up to 1.1 Gbps on the Gig1 package. Availability depends on whether Virgin Media has cabled your street. Cable tends to suffer from congestion during peak evening hours more than FTTP.

4G and 5G Home Broadband uses a mobile signal and a plug-in router instead of a fixed line. Three and EE both offer home broadband plans using their mobile networks. 5G can deliver speeds over 300 Mbps in well-covered areas, making it a genuine alternative to fibre. However, speeds vary significantly with signal strength and network congestion. It suits renters and those in areas with poor fixed-line options.

What Speed Do You Actually Need?

The answer depends on how many people use your connection simultaneously and what they do with it. A single person browsing the web and streaming standard-definition video needs only 10 Mbps. A household of four streaming 4K content on multiple devices, video calling, and gaming online should aim for at least 100 Mbps. Remote workers uploading large files or joining video conferences regularly should pay attention to upload speeds too, which are often far lower than download speeds on FTTC connections.

For gaming, latency matters more than raw speed. A stable 30 Mbps connection with low ping will outperform a 300 Mbps connection that drops packets. Wired Ethernet connections always deliver lower latency than Wi-Fi.

How to Check Your Current Speed

Run a speed test at speedtest.net or use Ofcom's official broadband performance tool. Test on a wired connection for accurate results, as Wi-Fi introduces its own limitations. Run tests at different times of day to see whether your speed drops during peak hours, typically between 7pm and 10pm.

Switching Provider: What You Need to Know

Since December 2023, Ofcom's One Touch Switch rules mean your new provider handles the entire switch for you. You do not need to contact your current provider to cancel. Simply sign up with the new provider and they will manage the transition, usually within ten working days. You will not lose service during the switch if both providers use the Openreach network.

Check your current contract end date before switching. Leaving mid-contract incurs early termination fees, which can be substantial. Most providers notify you when your minimum term ends. Once out of contract, you are free to leave at any time with thirty days notice.

Negotiating with your existing provider often yields a better deal than their standard renewal price. Call the cancellations team rather than general customer service. If they cannot match the best deal available elsewhere, switch without hesitation.

Tips for Getting the Best Deal

• Compare deals at the end of your contract, never mid-term
• Factor in the total contract cost, not just the monthly price — setup fees and price rises add up
• Look for providers that fix prices for the contract duration rather than applying annual increases
• Consider whether you need a TV or phone bundle — broadband-only deals are almost always cheaper
• Check cashback sites before signing up — many providers offer cashback through TopCashback or Quidco
