What broadband speed do I need?

Last updated: 29 February 2024   By Lyndsey Burton

Broadband is mainly sold by price or by speed, and while budgets are easy to work out, knowing what broadband speed you need can be trickier.

Broadband speeds have taken leaps and bounds over the last few years, and while the average broadband speed is now 69.4Mb per second across the UK, over 78% of homes can access speeds of up to 1,000Mbps if they want it.

But with faster broadband costing more each month, it's worth knowing what broadband speed you actually need to ensure you're not paying out more than you need to.

Broadband speed requirements come down to how large a household is, how many devices are connecting, and how the Internet is being used, whether that's browsing, streaming or gaming.

What is a good broadband speed?

A good broadband speed will vary between households and what they're online requirements are, for example if they stream TV, do they watch movies in 4K, or are they downloading large files like console games?

For most households superfast broadband will be adequate, so that's packages with download speeds between 30Mbps and 100Mbps.

However, larger households, or those with a lot of devices connecting to the Internet at the same time, will notice the benefit of full fibre or cable broadband deals that offer ultrafast speeds of 100Mb or more.

While over 78% of homes around the UK can now access gigabit-capable broadband with average download speeds between 900Mbps and 1,000Mbps, only the heaviest users, or largest households, really need broadband this fast.

These requirements are reflected in take-up rates of broadband around the UK, with industry regulator Ofcom reporting only 14% of homes that have full fibre availability take speeds of at least 900Mbps, with the majority (71%) signing up to packages offering at least 100Mbps.

Overall, as mentioned, a good broadband speed really depends on the household and their individual requirements. This can be looked at in one of two ways. Household size, i.e. the number of people likely to be going online at the same time and sharing the broadband connection, and most common online activities and what speeds that requires.

Broadband activities

For a further look at what broadband speed you might need, it's also worth considering how you use the Internet and what activities you carry out online.

Here are some minimum broadband speed requirements for different online activities:

Minimum required broadband speed
Streaming TV or films in HD 5Mbps
Streaming TV or films in 4K 25Mbps
Zoom meetings or video calls in HD 3Mbps (4Mbps upload)
Xbox Cloud Gaming 20Mbps
Playstation 5 online gaming 3Mbps

While these speeds seem low, they're absolute minimums, and because most households will have multiple devices connected to the router, including smartphones, the broadband speed needed will be much higher.

According to the latest Connected Nations report, Ofcom found the average monthly broadband usage of households across the UK is now 535GB, up from 482GB the year before.

It's likely the higher usage is down to streaming services from Netflix and more people watching TV and films on-demand. Downloading console games can also push usage figures higher, with games like Call of Duty having a file size of 220GB for the Black Ops Cold War version.

People who are streaming films and TV, or downloading and playing console games online, will want to consider broadband speeds of around 80Mbps or more, to ensure they're not slowed down by other users in their household.

Household size: 1 - 2 people

For households with only one or two people, the broadband speed needed will likely be around 30Mbps, unless particularly heavy bandwidth activities are taking place.

30Mbps is the entry level superfast tier for fibre to the cabinet (FTTC) connections, and is available to 97% of UK homes from a range of broadband providers.

Prices for 30Mbps broadband plans start at around £23 per month.

Household size: 2 - 4 people

Typical families with children are likely to need broadband speeds of between 30Mbps and 100Mbps.

This size of household is more likely to be using the Internet at the same time, and kids may be online gaming upstairs, while someone else wants to stream TV downstairs.

Having a slightly faster broadband speed will mean everyone get online at the same time without slowing down each other's online activity.

30Mbps to 100Mbps broadband plans are also available to 97% of UK homes, and prices range from £23 to £30 per month depending on the provider chosen.

Household size: 5 or more people

Larger households with multiple occupants, such as shared houses, or student houses, will want to consider faster broadband speeds to meet their needs.

It's likely in larger households multiple devices will be sharing the connection and people may be undertaken various online activities from working from home, cloud gaming, or streaming movies in HD.

For households of five or more people the broadband speed they will need is likely to be 100Mbps or more, which means looking for full fibre or cable broadband connections that support ultrafast speeds.

While full fibre broadband is currently online available to 57% of UK homes, gigabit capable broadband, which includes Virgin Media, is available to over 78% of homes. In addition, at least 21% of homes have a choice of two or more gigabit-capable networks, so prices are kept competitive.

100Mbps broadband plans are available from around £25 to £30 per month, with the fastest gigabit plans costing between £40 to £55 per month on average.

Broadband speeds available in your area

While working out the broadband speed you need is important, it's also worth checking the speeds available to your address, as this could affect what's available to choose from.

We know that broadband speeds of at least 30Mbps are now available to 97% of UK homes, while ultrafast and gigafast broadband speeds of 100Mbps or more are available to over 78%.

Virgin Media have the widest availability for ultrafast and gigabit-capable broadband, covering over 16 million premises across the UK, and offering the fastest broadband with average download speeds of 1.13Gb.

The other major broadband network, operated by Openreach, has reached 12.5 million premises with their full fibre broadband that can provide average download speeds of up to 900Mbps.

While broadband providers are racing to rollout faster networks, take-up is still catching up with availability.

For example, of the 57% of homes that can access full fibre broadband, so far, only 28% have upgraded, and only 14% of these take the fastest speed plan available to them, with the majority of full fibre customers opting for the entry level 100Mbps plans.

It's arguable then that the vast majority of homes on average speeds of 69.4Mb find their Internet connection adequate for their usage.

Benefits of faster broadband

Opting for a faster broadband package to meet a household's needs can provide several benefits.

Faster broadband allows more people and more devices to go online at the same time without affecting each other, for example a faster connection will stop 'buffering' and dropouts happening on one or more devices.

A faster connection can also download files in quicker times, as the below table demonstrates:

Superfast 30Mb Ultrafast 100Mb Gigafast 900Mb
Music album in MP3 (5MB) 1 second <1 second <1 second
200 photos (200MB) 1 minute, 2 seconds 18 seconds 2 seconds
One-hour TV show in SD (1GB) 5 minutes, 18 seconds 1 minute, 35 seconds 10 seconds
Two-hour movie in HD (6GB) 31 minutes, 48 seconds 9 minutes, 32 seconds 1 minute, 3 seconds
Playstation 5 FIFA 23 (50GB) 4 hours, 25 minutes, 7 seconds 1 hour, 19 minutes, 32 seconds 8 minutes, 50 seconds
Xbox Series X Assassin's Creed Valhalla (104GB) 9 hours, 11 minutes, 27 seconds 2 hours, 45 minutes, 26 seconds 18 minutes, 22 seconds

As you can see, even upgrading to 100Mbps broadband speeds make a considerable difference to the time it takes to download various files.

As more of our lives are carried out online with an increase in working from home, video calling, streaming TV shows and films, online gaming and cloud gaming, having a faster broadband speed can allow us to carry out our online activities quickly and without hindrances of slow download times or sluggish connections.

Summary: 100Mb broadband soon to be the standard speed

The broadband speed you need will depend on individual requirements, as well as how many people are sharing the connection within a household.

For most homes, superfast broadband between 30Mbps and 100Mbps will be adequate, but as the full fibre rollout continues and the copper phone line network is eventually retired, 100Mbps+ broadband speeds will become the norm.

For now, larger households with multiple users or those carrying out bandwidth heavy activities like streaming in 4K or online gaming may want to upgrade to ultrafast and even gigabit broadband speeds.

To recap, the broadband speeds needed for different household sizes are approximately:

  • 1 to 2 people: 30Mbps should be suitable
  • 2 to 4 people: 30Mbps to 100Mbps will support multiple devices
  • 5 or more people: 100Mbps+ broadband should be considered
