What is the Fastest Broadband Speed You Can Get in 2025?

As of 2025, the average internet speed in the UK has reached 73.21 Mbps, which is a growth of over 12% since September 2022. Average upload speeds also rose significantly, climbing by 18% between September 2022 and March 2023 to 18.4 Mbps. Data from Ofcom also reveals that 99.7% of UK households now have access to reliable internet speeds of 10 Mbps or higher.

Broadband speeds can vary significantly across different regions and even between streets. For instance, a recent study analyzed nearly 208,000 internet speed tests and found that while some areas enjoy high-speed connections, others experience much slower speeds.

Factors influencing these variations include the type of broadband technology available (such as full fibre or ADSL), the infrastructure in place, and the level of investment in digital connectivity within specific areas.

In 2025, the fastest broadband speeds are through full fibre connections, which can deliver speeds up to 10 gigabits per second (Gbps) to your home. However, most homes with full fibre access are currently capped, with maximum speeds reaching around 1 Gbps (1,000 Mbps), or 1130mbps with our Gig1 broadband.

This is more than fast enough for almost every online activity you can think of, from 4K streaming to competitive online gaming and live streaming.

It's important to note that the fastest speed you can get depends on where you are. If you live in urban areas like London, you’re more likely to have access to some of the fastest speeds available in the UK.

Our Gig1 has been rolled out across our entire network, so you’ve a fair chance of getting our fastest broadband speed yet. Not sure what you can get? Use our helpful postcode checker to see the fastest speeds available your area.

The fastest broadband speed ever recorded anywhere in the world was 319 Terabits as part of an experiment by University College London in 2020. That’s 319,000,000 Mbps, and roughly 5 million times faster than the average speed in the UK.

The speed came in 2020, when engineers at University College London achieved a data transfer rate of 178 Terabits per second or 178,000,000 Mbps. To put this into perspective, you’d be able to download every film and TV show on Netflix in less than one second. These impressive speeds beat the previously held record for fast data transmission by one-fifth.

This incredible speed was only achieved thanks to specific experimental conditions, and it's not anywhere near what you actually need or can realistically get at home.

A fast broadband speed is generally considered to be anything above 100 Mbps (megabits per second). This speed is enough to handle most online activities, even if multiple people are using the internet at the same time.

With a 100 Mbps connection, you can stream videos in 4K quality, play online games without lag, and download large files quickly. It also allows for smooth video calls and fast web browsing, even when several devices are connected at once.

However, what counts as "fast" can change depending on your needs. For a single person who mostly streams videos and checks social media, a speed of 50–100 Mbps might feel fast enough. But for a family or a household where people are streaming, gaming, and working from home all at the same time, speeds of 200 Mbps or higher may be necessary for a smooth experience.

And for anyone that wants ultra-fast speeds, gigabit broadband with speeds 1Gbps (1,000 Mbps and beyond is considered one of the best speeds you can get. These speeds allow almost instant downloads and smooth performance, even with many connected devices.

While our gigabit broadband is the fastest speed we offer in the UK, we’ve got a range of superfast broadband options to suit everty household.

Here’s a breakdown of our broadband speeds and wha they’re suitable for:

If your home broadband speed isn’t quite as quick as you need it to be, there are some things that you can do to help. The first is to check what package you’re currently on, take a look at the number of devices your household uses and determine whether or not your existing broadband package is right for you.

One option may be upgrading your existing package to one which has faster speeds, such as fibre broadband. By upgrading to superfast broadband speeds, your home broadband should deliver faster speeds so you can browse, game and stream online without slowing down. Find out how to decide which broadband speed you need.

The second way to get faster internet speeds is to change providers. You may find that your existing provider cannot offer significantly faster speeds than what you have now, or can’t offer these speeds at a price that suits your budget. In this case, it’s worth exploring options available from other vendors.

A final consideration is to upgrade your hardware. If you already have a speedy internet package, you could explore options such as switching your router to one that supports newer WiFi standards. While this wouldn’t affect the speed of the internet coming into your home, it could help to maintain these high speeds between your router and your devices.

With the bustling digital demands of cities like London and Birmingham, staying ahead of the average broadband speed is crucial for both work and leisure.

Our gigabit broadband deals are tailored to meet these demands, offering speed of up to 13 times the national average, so you’re always connected at the speed you need. Not sure if gigabit broadband is for you?
