You use your broadband the same way you always have, so why does everyone say you need faster broadband? Here's what's changed, and how to tell if you really need to upgrade

You may need more speed even if your habits haven't changed, because the same things now use more data: 4K streaming, bigger game and app downloads, heavier web pages and more devices. Average home data use rose 10% in a year. But before you upgrade, test your speed on a cable: if that's fine, the problem is likely inside your home (the Wi-Fi, router or a device), not your line. Ofcom says 30 to 300 Mbit/s suits most everyday use, and plans up to 299 Mbps often cost no more than slower ones.

What it means for youChecked 11 November 2026

If your speed tests fine on a cable: you probably don't need a faster plan. Fix the Wi-Fi instead, starting with where the router sits. RouterMap helps.

If several of you stream, game and work at once: add up what happens at your busiest hour with RightSpeed. If the total is above your line speed, an upgrade will help.

If you're still on an older copper or part fibre line: check what full fibre costs at your address. In our check, plans up to 299 Mbps were often no dearer than slower ones.

Key facts, verified 11 November 2026

  • Average monthly data use per home broadband connection was 583GB in July 2025, up 10% from 531GB a year earlier (Ofcom, 30 June 2026).
  • Ofcom says superfast broadband, 30 to 300 Mbit/s, "suits most everyday use, such as working from home, video calls and streaming" (Ofcom, updated 25 August 2026).
  • Ofcom's rough guide gives 30 Mbit/s for one person streaming Ultra HD video and 10 Mbit/s for an HD video call (Ofcom, updated 25 August 2026).
  • Netflix recommends 15 Mbps or higher for 4K, and 5 Mbps for 1080p HD (Netflix, checked 11 November 2026).
  • The median mobile web page grew from 845KB in July 2015 to about 2.56MB in 2025, a 202.8% increase (HTTP Archive, 15 January 2026).
  • A slow Wi-Fi test "does not always mean there is a fault with your broadband line" (Ofcom, updated 25 August 2026).
  • Full fibre reaches 82% of UK homes, and 47% of premises that can get it have taken it up (Ofcom, 13 May 2026).
  • Ofcom says many customers can switch to faster full fibre "and pay the same, or less" than they pay for copper or part fibre (Ofcom, 26 February 2026).
  • Social tariffs "range from £12.50 to £24 a month for broadband", but 70% of eligible households don't know they exist (Ofcom, 26 February 2026).

Who this is for: anyone wondering whether they really need a faster plan: people whose provider has suggested an upgrade, families with more devices than ever, people working from home, gamers, and older readers who use the internet much as they always have. We follow one example: Pauline and her husband Ray have had the same 36Mbps line for years, and their provider has just suggested an upgrade. Pauline is an example built from the calls we take on our help line, not a real customer.

Why would I need more broadband speed if I use it the same way?

Direct answer: Because the same things now use more data. Films stream in higher quality, games and app updates are much bigger, web pages are heavier and more devices are online at once. Average home data use rose 10% in a year.

This was one of the questions callers brought to our help line this month, and it's a fair one. If you watch the same programmes, browse the same sites and call the same people, why would you need more?

The answer is that the internet keeps getting heavier around you. Streaming services offer higher quality, phones and TVs update themselves, games arrive as huge downloads, and the typical mobile web page is three times the size it was ten years ago. None of that needs you to change a thing. It simply happens in the background.

But that's only half the story. Plenty of people who feel they need more speed actually have a Wi-Fi or router problem, and a faster plan won't fix that. So this guide covers both: why needs grow, and how to tell whether you really need to pay for more.

How much more data are UK homes using?

Direct answer: About 10% more in the latest year. Ofcom says average use per home broadband connection was 583GB a month in July 2025, up from 531GB in July 2024. On its earlier measure, use rose 11% to 535GB in 2023.

Ofcom's Communications Market Report 2026 says "Average monthly data use per residential fixed broadband connection (including uploads and downloads) was 583 GB in July 2025", compared with 531GB a year earlier. Its 2024 report says use "increased by 53 GB per month (11%) to 535 GB in 2023", and its 2023 report put 2022 at 482GB, up 6% on the year before.

One thing to know: Ofcom changed how it collects these figures in 2024, so the dip from 535GB to 531GB can't be read as a real fall. Ofcom's 2024 methodology notes say the newer monthly averages "are not directly comparable with those in previous reports". Compare within each pair and the story is similar: 11% more in 2023, and 10% more in the year to July 2025.

Homes on full fibre use more again: Ofcom's Connected Nations 2025 puts the full fibre average at 738GB a month. That may partly be because heavier users tend to choose full fibre, so it doesn't mean switching will make you use more.

For the bigger picture, see our UK Broadband in Numbers tracker, updated monthly.

Are web pages and apps really getting bigger?

Direct answer: Yes. The HTTP Archive, which measures millions of websites, found the median mobile web page grew from 845KB in 2015 to about 2.56MB in 2025, three times the size. It grew 8.4% in the last year alone.

The HTTP Archive's Web Almanac (15 January 2026) says "The median home page in 2025 was 2.86 MB on desktop and 2.56 MB on mobile". Over ten years, it says mobile pages grew by 202.8%. Every photo, video clip and script on a page has to come down your line before the page feels finished.

It's the same story with apps and games. Phones, tablets, smart TVs and consoles download updates on their own, and the biggest games now arrive as downloads of 100GB or more: GTA 6 is up to 212GB. That's why a line that felt quick five years ago can feel tired now, even with the same people using it.

What speed do streaming, video calls and gaming actually need?

Direct answer: Less than you might think, one at a time. Netflix recommends 15 Mbps for 4K, Ofcom's guide gives 30 Mbit/s for one Ultra HD stream and 10 Mbit/s for an HD video call. It's doing them all at once that adds up.

Here are the official figures, from the companies and from Ofcom's rough guide. Notice the upload column: video calls send as well as receive, which matters later.

Sources: Netflix's recommended speeds and Microsoft's Teams network guide, which recommends 2.5 Mbps up and 4 Mbps down for each device in a video meeting. Ofcom's own description of each speed band is useful too: standard, up to 30 Mbit/s, is "enough for basic browsing, email and standard video", while ultrafast, 300 Mbit/s or more, is "better if several people are online at once".

How much speed does a busy household use at once?

Direct answer: Add up what happens at your busiest hour. On Ofcom's figures, one Ultra HD stream, one HD video call and some browsing come to about 41 Mbit/s. Two streams, a call and two people browsing come to about 72 Mbit/s.

This is where Pauline and Ray's question gets its answer. Most evenings, Ray watches football in Ultra HD while Pauline video-calls their grandchildren. Using Ofcom's figures, that's 30 plus 10 plus a little browsing: about 41 Mbit/s, on a 36Mbps line.

On Ofcom's figures, their busiest hour needs slightly more than their line can give, which could explain why the picture freezes some evenings. A test on a cable would confirm it, and if so, a modest upgrade would cover them with room to spare. They don't need gigabit. On Ofcom's rough guide, even a busy family evening comes to well under 100 Mbit/s, and Ofcom says 30 to 300 Mbit/s suits most everyday use.

Is upload speed the hidden bottleneck?

Direct answer: Often, yes, for video calls and backups. Microsoft recommends 2.5 Mbps up for each device in a Teams meeting, and photo backups and file sharing use the same upload. Many part fibre lines have far less upload than download.

Most adverts lead with download speed, but video calls, cloud photo backups and sending files all use your upload. If two people are on calls while a phone backs up its photos, the upload can run out long before the download does.

When you test your line, check the upload figure as well as the download. If calls freeze while everything else seems fine, our guide to broadband dropping on video calls explains why upload is often the cause.

Why does my broadband feel slower than it used to?

Direct answer: Often it's something at home rather than the line: the Wi-Fi, an older router, one struggling device or something downloading in the background. Ofcom says a slow Wi-Fi test does not always mean a fault with your line.

Ofcom's help page is clear: "A slow Wi-Fi test does not always mean there is a fault with your broadband line." It points to the router, the device, distance from the router, walls and interference. It also says "If one device is much slower than the others, the problem might be with that device rather than your broadband."

Ofcom's tips for faster broadband at home add that if your router is older, or your line keeps disconnecting, an upgrade might help. So ask your provider about a newer router before you pay for a faster plan.

Background traffic matters too. Phones, tablets and smart TVs update themselves, and a console can pull down a huge game while you're trying to stream. If your broadband feels slow only at certain times, check what else is running before you blame the line. If it keeps dropping out, that's a different problem with a different fix.

Do I actually need to upgrade?

Direct answer: Only if a test on a cable shows your line can't keep up with your busiest hour. If the cabled speed is close to what you pay for and still falls short, upgrade. If it's fine on a cable, fix your Wi-Fi instead.

Run your test on UKSpeedTest with a laptop plugged into the router, once in the day and once in the evening. If the cabled speed is well below the minimum guaranteed speed your provider gave you, that's a fault, not a reason to pay more. Under Ofcom's speeds code, providers that have signed up, including BT, EE, NOW, Plusnet, Sky, TalkTalk, Utility Warehouse, Virgin Media and Zen, must fix a speed problem on their network within 30 days or let you leave without an early exit fee.

If the cable test is fine but the Wi-Fi isn't, a faster plan won't help. Move the router into the open, keep it away from other electrical kit, and use RouterMap to find the best spot. Our guide to free ways to improve your Wi-Fi has more.

Does faster broadband cost more?

Direct answer: Often not much, and sometimes less. In our check of 360 deals on 1 November 2026, the median 24-month deal at 100 to 299 Mbps cost £24.99 a month, less than plans under 100 Mbps at £26.99.

We check every deal on our monthly deals page by hand. On 1 November 2026 that was 360 broadband-only deals from 32 providers. Here's the median monthly price of the 24-month deals, grouped by advertised average speed.

So the slowest plans weren't the cheapest. About a third of the deals under 100 Mbps run on part fibre or copper lines, while the 100 to 299 Mbps band is almost all full fibre (62 of 70 deals). Going from 100 to 299 Mbps up to 600 to 999 Mbps added about £9 a month at the median (£24.99 to £34.00), which is worth paying only if your busiest hour needs it.

This is in line with Ofcom's own research. In February 2026 it said that "In many cases, customers can switch to a faster, more reliable full-fibre broadband service and pay the same, or less", and that broadband prices fell in real terms in 2025: "Across various different speeds, prices decreased by 6% on average." Whatever you choose, check the setup fee and the yearly price rise, which our deals table shows for every deal.

Is full fibre worth it if I can get it?

Direct answer: Usually, if it costs about the same. Full fibre reaches 82% of UK homes, but only 47% of premises that can get it have taken it up. If you're one of the others, it's worth comparing prices at your address.

Ofcom's spring 2026 update says full fibre "is available to 24.9 million UK residential premises (82% of the UK's 30.5 million homes)", and that take-up of 12.4 million "corresponds to 47% of all premises with access to full fibre."

You don't have to take the fastest full fibre plan. Many providers offer entry-level full fibre in the 100 to 300 Mbps range, and our check found that band had the lowest median price. Switching is led by your new provider under One Touch Switch, and our guide to full fibre on your street explains what changes at home.

Do big game downloads need a faster line?

Direct answer: They're where extra speed shows most. Rockstar says GTA 6 needs up to 212GB. At full line speed that's about 13 hours on 36Mbps, 4 hours 43 minutes on 100Mbps and 31 minutes on 900Mbps.

If someone at home plays on a console, downloads are often the biggest single job your broadband does. Rockstar says "The pre-load file will require up to 212 GB depending on your device" for Grand Theft Auto VI, which launches on 19 November 2026.

For most people, a long download overnight is fine. It matters more if the same line is needed for work calls during the day, or if downloads keep landing at the busiest time. Our download time calculator works it out for any size and speed.

Is there cheaper broadband if I'm on benefits?

Direct answer: Yes. Social tariffs are cheaper plans for people on Universal Credit, Pension Credit and some other benefits. Ofcom says they range from £12.50 to £24 a month, but 70% of eligible households don't know they exist.

Ofcom says "532,000 customers were using a social tariff in June 2025", that "70% of eligible households don't know they exist", and that the number of tariffs "has grown from just three in 2020 to more than 30." Many offer real speed, too: on our deals page, social tariffs run from 15 Mbps to over 150 Mbps.

Alex's closing thought

Speed questions were on our help line again this month, and I like this one, because the honest answer isn't always "buy more". The internet really has got heavier around us, so a line that was plenty a few years ago can start to pinch. But no plan, however fast, can fix a router shut away in a cupboard. Test on a cable, add up your busiest hour, then choose. And if you'd like someone to look at it with you, ring us on 0330 122 1223.

Frequently asked questions

Why would I need more broadband speed if I use the internet the same way?

The same activities now use more data: higher quality streaming, bigger game and app updates, heavier web pages and more devices. Ofcom says average home data use rose 10% between July 2024 and July 2025.

Is 100Mbps enough for a family?

For most families, yes. On Ofcom's rough guide, two Ultra HD streams, an HD video call and some browsing come to about 72 Mbit/s. Add up your own busiest hour to be sure.

Is 500Mbps worth it?

It can be if several people stream, game and download at once. Ofcom says ultrafast is better if several people are online at once. Check whether it costs more at your address first.

Do I need 900Mbps broadband?

Rarely for everyday use. It mainly speeds up very large downloads: a 212GB game takes about 31 minutes at 900Mbps against about 57 minutes at 500Mbps, at full line speed.

What speed do I need for 4K streaming?

Netflix recommends 15 Mbps or higher for 4K (Ultra HD). Ofcom's rough guide allows 30 Mbit/s for one person streaming Ultra HD video.

What speed do I need to work from home?

Ofcom gives 10 Mbit/s for an HD video call, and Microsoft recommends 4 Mbps down and 2.5 Mbps up per device for Teams meetings. Check your upload speed as well as your download.

Why is my broadband slower than it used to be?

It's often the Wi-Fi, an older router, one struggling device or background downloads. Ofcom says a slow Wi-Fi test does not always mean a fault with your broadband line, so test on a cable first.

How much data does the average UK home use?

Ofcom says average use per home broadband connection was 583GB a month in July 2025, including uploads and downloads. Homes on full fibre averaged 738GB.

Does faster broadband cost more?

Often not much. In our check of 360 deals on 1 November 2026, the median 24-month deal at 100 to 299 Mbps cost £24.99 a month, less than plans under 100 Mbps at £26.99.

Will a faster plan fix my Wi-Fi?

No. If your speed is fine on a cable but poor over Wi-Fi, the problem is inside your home. Move the router into the open, away from other electrical kit, or, if your router is old, ask your provider about a newer one.

What if my speed is below what I was promised?

If you're with a provider signed up to Ofcom's speeds code (BT, EE, NOW, Plusnet, Sky, TalkTalk, Utility Warehouse, Virgin Media or Zen), it must fix a speed problem on its network within 30 days or let you leave your contract without an early exit fee.

Is there cheaper broadband for people on benefits?

Yes. Ofcom says social tariffs range from £12.50 to £24 a month for broadband, but 70% of eligible households don't know they exist.
