What do my broadband speed test results mean?
Your test shows four numbers — here’s how each one translates to real-world performance on a UK broadband connection.
Download speed (Mbps)
How quickly data arrives at your device — the speed that matters for streaming, browsing, downloading files and pulling Zoom video. UK averages: ~36 Mbps on a copper FTTC line, ~67–80 Mbps on entry full-fibre (FTTP), 150–500 Mbps on mid-range fibre, 900 Mbps+ on gigabit packages from BT, Sky, Virgin Media, Hyperoptic, Community Fibre, Vodafone or Gigaclear.
Upload speed (Mbps)
How quickly data leaves your device — matters for video-call quality, cloud backups, photo sharing, hosting and live streaming. Older FTTC packages cap upload at ~20 Mbps; full-fibre lines usually deliver 30–110 Mbps; symmetrical packages from Hyperoptic, Zen and Gigaclear give equal upload and download.
Ping / latency (ms)
The round-trip time for a single tiny packet from you to our UK server and back. Under 20 ms is excellent (typical fibre); 20–50 ms is fine for gaming and video calls; 50–100 ms is usable; over 100 ms and you’ll feel input lag on competitive games and noticeable delay on calls. High ping on fibre usually points to wifi or router issues, not the line itself.
Jitter (ms)
The variation between successive ping measurements — a low number means consistent latency, a high number means “jumpy” performance that audibly stutters voice calls and Zoom. Under 5 ms is excellent; under 30 ms is acceptable; over 30 ms causes audible glitches on calls and rubber-banding in online games. Jitter is usually caused by congested wifi or a saturated upstream queue, not the broadband package itself.
Speed test guidance by UK broadband provider
Different UK ISPs use different underlying technologies — Openreach FTTC, Openreach FTTP, CityFibre, Virgin’s DOCSIS cable, Hyperoptic’s own apartment-block FTTP, 5G fixed wireless — and each has its own expected speed profile and quirks. Here’s what to look for in your result based on who you’re with:
BT broadband speed test
BT broadband runs on a mix of Openreach FTTC (copper-to-cabinet) and Openreach FTTP (full fibre), depending on what’s in your street. The four BT packages you’re most likely on are Fibre 1 (target 36 Mbps download, 9 Mbps upload), Fibre 2 (74/19 Mbps), Full Fibre 100 (150/30 Mbps), Full Fibre 500 (500/73 Mbps) and Full Fibre 900 (900/110 Mbps).
On a wired ethernet connection at off-peak hours you should hit 90–100% of the headline speed. BT also publishes a per-postcode minimum guaranteed speed when you sign up — if your test result drops below that figure for three days, you can leave the contract penalty-free under Ofcom’s broadband speed code (see below). For diagnostic comparison, BT Wholesale also runs its own test at bt.com/help/broadband; if their figure is materially higher than ours, the bottleneck is inside your home network (wifi, router, congested switch) rather than on the line.
Sky broadband speed test
Sky broadband resells the same Openreach FTTC and FTTP infrastructure that BT, TalkTalk and Plusnet use, with Sky-branded routers (typically the Sky Hub or the newer SR203 / Max Hub). Common packages: Essential (target 11 Mbps), Superfast (61 Mbps), Ultrafast (145 Mbps), Gigafast (900 Mbps).
Sky guarantees a minimum download speed in your contract; if your wired speed sits below it for three consecutive days, Sky must investigate, fix or release you from the contract. Our test gives an independent measurement against a UK server — if your wifi result here is much lower than expected, try plugging directly into the Sky Hub with ethernet and re-testing before assuming the line is at fault.
Virgin Media broadband speed test
Virgin Media operates its own cable network using DOCSIS 3.1 (and increasingly XGS-PON full fibre on newer Project Lightning builds). Headline speeds: M50 (54 Mbps), M125 (132 Mbps), M250 (264 Mbps), M350 (362 Mbps), M500 (516 Mbps), Gig1 (1130 Mbps download, 50 Mbps upload), Gig2 (2000 Mbps).
Virgin’s key quirk is heavily asymmetric upload on DOCSIS lines — even on Gig1 the upload tops out at 50 Mbps, well below full-fibre rivals. If your upload reading here is much lower than your download, that’s normal for Virgin cable. On newer XGS-PON full-fibre Virgin lines uploads can run symmetrical. Use Virgin’s My Virgin Media app to confirm which technology you’re on.
TalkTalk broadband speed test
TalkTalk runs over Openreach copper FTTC and FTTP, plus its own CityFibre wholesale full-fibre footprint in selected UK cities. Common packages: Fibre 35 (38 Mbps), Fibre 65 (67 Mbps), Future Fibre 150 (152 Mbps), Future Fibre 500 (528 Mbps), Future Fibre 900 (944 Mbps).
TalkTalk includes a download speed guarantee — you’ll see your personal minimum in your contract. If our test shows you’re below it on a wired ethernet connection at off-peak hours, you can ask TalkTalk to fix the line or release you from contract. TalkTalk is also one of the ISPs most often affected by peak-hour congestion on copper FTTC; if your evening speed is half your daytime speed, that’s the symptom.
Plusnet broadband speed test
Plusnet is BT-owned and uses the same Openreach lines as BT itself. Standard packages: Unlimited Fibre (36 Mbps download, 10 Mbps upload), Unlimited Fibre Extra (66 Mbps / 19 Mbps), Full Fibre 74 (74 Mbps), Full Fibre 145 (145 Mbps), Full Fibre 500, Full Fibre 900.
Because Plusnet shares BT’s infrastructure your results here should match what you’d see on a BT line in the same postcode. If you’re still on Plusnet’s ADSL copper-only product (no fibre cabinet in your area), expect 6–15 Mbps depending on distance from the exchange — well below the Ofcom decent-broadband baseline and a candidate for the Universal Service Obligation upgrade scheme.
EE broadband speed test
EE (BT-owned) runs over Openreach FTTC and FTTP. Packages are sold as Fibre Plus 67, Fibre Plus 100, Fibre Plus 300, Fibre Plus 500 and Fibre Plus 900, plus a small remaining ADSL footprint. EE also offers 4G/5G Home Broadband for areas without good fixed-line fibre.
On Openreach fibre, EE results here will mirror BT/Plusnet. On EE 4G/5G Home Broadband, expect highly variable results depending on signal strength, time of day and how busy the local cell is — 50–300 Mbps is typical on 5G, dropping to 10–50 Mbps on 4G. If you’re on 5G Home Broadband, running the test at different times of day (and in different rooms) builds a much truer picture than a single reading.
Vodafone broadband speed test
Vodafone broadband uses CityFibre’s full-fibre network where available, otherwise Openreach FTTC. Packages: Fibre 38 (38 Mbps), Fibre 76 (76 Mbps), Full Fibre 100 (100 Mbps), Full Fibre 200 (200 Mbps), Full Fibre 500 (500 Mbps), Full Fibre 900 (910 Mbps), Full Fibre 2 Gig (2000 Mbps).
Vodafone’s CityFibre full-fibre packages are symmetric — upload should match download. If you see a 900 Mbps download and 100 Mbps upload that means you’re actually on the Openreach FTTC product, not CityFibre full fibre. Vodafone also includes a download speed guarantee in your contract under the Ofcom code.
Hyperoptic broadband speed test
Hyperoptic runs its own pure full-fibre network (FTTP) focused on apartment blocks and dense urban developments. Every package is symmetric — upload always matches download. Tiers: Fast (50/50 Mbps), Superfast (150/150 Mbps), Ultrafast (500/500 Mbps), Hyperfast (1 Gbps / 1 Gbps).
Because Hyperoptic terminates fibre inside your building you should see results extremely close to the headline number on a wired ethernet connection. If your test reads much lower than expected, it’s almost certainly your wifi (try ethernet directly into the Hyperoptic router) or an old router (1 Gbps WAN port needed for the Hyperfast package). Hyperoptic’s symmetric upload is one of the strongest in the UK market.
Zen broadband speed test
Zen Internet sells FTTC and FTTP packages over the Openreach and CityFibre networks. Packages: Standard Broadband, Superfast 1 (38 Mbps), Superfast 2 (67 Mbps), Full Fibre 100, Full Fibre 300, Full Fibre 500, Full Fibre 900 and Full Fibre 1000 (symmetric on Openreach FTTP).
Zen is consistently rated highest for customer service and connection stability in Which? & Uswitch surveys. On wired ethernet your test result should sit within 5–10% of the headline speed for that package. Zen also runs an in-house speed-test tool, which sometimes reports higher because it tests to a server inside Zen’s own network — our independent test gives a real-world figure against a neutral UK server.
Gigaclear broadband speed test
Gigaclear builds and operates its own pure full-fibre network focused on rural and semi-rural communities. Every package is symmetric. Tiers: Easy 100 (100/100 Mbps), Easy 200, Easy 400, Easy 600, Easy 900 (900/900 Mbps), Easy 1100.
Gigaclear’s independent FTTP network means there’s no Openreach copper hop to slow things down — ethernet results should sit very close to the headline number. The most common cause of below-expected results on Gigaclear is older wifi hardware that can’t shift more than ~400 Mbps over Wi-Fi 5; upgrading to a Wi-Fi 6/6E router unlocks the full package.
Community Fibre broadband speed test
Community Fibre is a London-only full-fibre ISP using its own FTTP network. Every package is symmetric (upload = download). Tiers: 150 Mbps, 300 Mbps, 500 Mbps, 1 Gbps, 3 Gbps.
On ethernet, Community Fibre results should sit within 5% of the headline speed. The 3 Gbps tier needs a 2.5 GbE or 10 GbE port to be measurable in a browser — most laptops cap at 1 Gbps so the test will read close to 1000 Mbps even on the 3 Gbps package. Symmetric upload makes Community Fibre particularly strong for video creators, cloud backups and home-hosted services.
Three / 5G Home Broadband speed test
Three’s 5G Home Broadband uses the Three mobile network rather than a wired line, delivered via a 5G hub. Speeds are inherently variable — they depend on which mast you’re on, how busy that mast is, and signal strength inside your home.
Typical results: 100–500 Mbps download on 5G mid-band, dropping to 20–80 Mbps if you fall back to 4G, with upload usually 10–50 Mbps. Test multiple times across the day — a single reading is misleading on 5G home broadband because evening congestion routinely halves throughput. Three doesn’t give a guaranteed minimum speed on 5G Home, so the Ofcom broadband speed code doesn’t apply.
What counts as a good UK broadband speed?
There’s no single “good” speed — what you need depends on how many people are online at once and what they’re doing. Here are the realistic targets for a UK household, based on Ofcom guidance and what each activity actually consumes:
| Use case | Recommended download speed | Recommended upload speed |
|---|---|---|
| Single person — browsing, email, social, SD streaming | 10–30 Mbps | 1–3 Mbps |
| Couple — two simultaneous HD streams + one video call | 30–60 Mbps | 5–10 Mbps |
| Family of 3–4 — HD/4K streams, gaming, calls in parallel | 60–150 Mbps | 10–30 Mbps |
| Heavy household / hybrid worker — multiple 4K streams, large uploads, cloud backups | 150–500 Mbps | 30–100 Mbps |
| Power user / content creator — live streaming, multi-cam uploads, smart home, mesh wifi | 500 Mbps–1 Gbps | 100–1000 Mbps (symmetric) |
How much speed do specific activities need?
- Netflix / Disney+ / Amazon Prime SD streaming: ~3 Mbps per stream.
- HD streaming: ~5–8 Mbps per stream.
- 4K UHD streaming: 15–25 Mbps per stream (Netflix recommends 15, BBC iPlayer 4K up to 25).
- Zoom / Microsoft Teams / Google Meet HD video call: ~3 Mbps down + 3 Mbps up.
- Online gaming (Xbox / PS5 / Switch / PC): low bandwidth (~3–6 Mbps) but very sensitive to ping and jitter — aim for under 50 ms ping.
- Console game download: a typical 80 GB AAA title takes about 12 minutes on 1 Gbps, 1.5 hours on 100 Mbps, 5 hours on 36 Mbps.
- Cloud backup (Dropbox / iCloud / OneDrive): limited by upload speed — 100 GB takes ~25 minutes at 1 Gbps symmetric, ~12 hours at 20 Mbps upload.
How to improve your broadband speed
If your test result is well below what your package promises, work through these checks in order — most home broadband problems are wifi, router or device issues rather than line faults.
1. Test on wired ethernet first
Plug a laptop directly into your router with a Cat5e/Cat6 ethernet cable and re-run the speed test. If the wired result is close to your package headline but wifi is much slower, the bottleneck is your wifi — not your broadband line. The most common causes: an old router (Wi-Fi 5/AC and earlier can’t shift more than ~400 Mbps reliably), distance from the router, and 2.4 GHz interference from microwaves / baby monitors / Bluetooth devices.
2. Reboot the router
Power off your ISP router for 60 seconds, then back on. This clears a stuck DSL re-train, a corrupted DHCP lease pool or a memory leak in the router firmware — all of which can quietly halve performance without showing any obvious error.
3. Check who else is on your network
Streaming devices, console game updates, security camera feeds, and cloud-backup software can each saturate 10–50 Mbps without you noticing. Pause backups, log into your router admin and look for unusually busy devices, or check Activity Monitor / Task Manager for high network usage.
4. Update or replace your router
ISP-provided routers (BT Smart Hub, Sky Hub, Plusnet One, Virgin Hub 3/4/5, TalkTalk Wi-Fi Hub) are competent for entry-level packages but often bottleneck on gigabit fibre. If you’re on 500 Mbps+ and wired-ethernet results to the router are low, upgrade the router or add a mesh wifi system (Eero, TP-Link Deco, Google Nest Wifi, Netgear Orbi).
5. Move the router
Routers belong central in the home, off the floor, away from metal objects, fish tanks, kitchen appliances and big mirrors. Routers shoved into a TV cabinet or behind a sofa lose 50–80% of their wifi range. Don’t hide the router.
6. Use the 5 GHz band (or 6 GHz on Wi-Fi 6E)
2.4 GHz wifi tops out around 100–150 Mbps in real-world use and is heavily congested in dense housing. 5 GHz delivers 300–900 Mbps but has shorter range. Modern phones and laptops auto-pick the best band, but very old or budget devices stick to 2.4 GHz — check your router admin to see what each device is connected to.
7. Run our test at different times of day
If you’re fast at 3 PM but slow at 8 PM, that’s peak-hour contention on your ISP’s network or the local exchange — common on TalkTalk, Plusnet and budget MVNOs that share backhaul. If contention is the cause, switching to a full-fibre ISP usually resolves it because FTTP traffic isn’t aggregated the same way.
Your rights: the Ofcom broadband speed code
You can leave your contract penalty-free if your speed is too low
The major UK ISPs that signed Ofcom’s Voluntary Code of Practice on Broadband Speeds (BT, EE, Plusnet, Sky, TalkTalk, Virgin Media, Vodafone, Zen and Hyperoptic) must give you a personal minimum guaranteed download speed when you sign up. If your real-world speed drops below that figure for three consecutive days, and the ISP can’t fix it within 30 days, you can leave the contract — including any landline or TV bundled with it — without an early-termination fee.
To use that right, you need independent evidence of the underperforming speed, and the test must be on a wired ethernet connection (wifi readings don’t count, because wifi performance varies by location and device). Save screenshots of multiple test results from this page across different times of day for the strongest case.
The Universal Service Obligation: 10 Mbps minimum
Under the UK government’s Universal Service Obligation (USO), every household and small business has the legal right to request a broadband connection of at least 10 Mbps download and 1 Mbps upload, provided the cost of building the connection is under £3,400. If you live in a rural area and your current speed is below the USO threshold, you can apply through BT (or KCOM in Hull) to have your line upgraded — details at ofcom.org.uk.
Broadband speed test FAQ
How accurate is this broadband speed test?
The test runs against a dedicated 1 Gbps UK server hosted on bare-metal hardware, using 16 parallel TCP streams for download and 8 for upload — the same multi-stream approach used by Ookla Speedtest and Cloudflare Speed Test. The result is your real end-to-end throughput from your device, through your wifi/ethernet, through your router, through your ISP, to a neutral UK test server. For the most accurate reading, plug your device into the router directly with an ethernet cable, close other apps, and pause any active downloads.
Why is my wifi speed test result so much lower than my package speed?
Wifi adds losses at every step: the wifi standard your router supports (Wi-Fi 5 / 6 / 6E / 7), your device’s wifi card, distance from the router, walls in between, 2.4 GHz interference from microwaves / Bluetooth / neighbouring networks, and the number of other devices sharing the channel. It’s normal for wifi to deliver 30–60% of your package speed on the far side of a house. Test wired first to isolate the wifi component, then upgrade to mesh wifi or move the router central if the wifi gap is the bottleneck.
What is jitter and why does it matter?
Jitter is the variation in ping (latency) between successive measurements. If every ping arrives at exactly 20 ms, jitter is 0 ms — perfect. If pings bounce between 15 ms and 80 ms, jitter is high. Low jitter (under 5 ms) is essential for voice calls, video conferencing, multiplayer gaming and anything real-time, because packets need to arrive in a steady stream — not in bursts. High jitter on a fibre line almost always points to wifi or upstream queue congestion, not the line itself.
What is packet loss?
Packet loss happens when data packets sent across the network never arrive, and have to be re-sent. A small amount (under 1%) is normal and unnoticed; anything above ~2% degrades video calls (frozen frames, robotic audio) and online games (rubber-banding, dropped shots). Packet loss is usually caused by a degraded or noisy line, a saturated link somewhere in the path, or a failing piece of network hardware. If our test reports high packet loss consistently, it’s worth getting your ISP to run a line test.
What’s the difference between Mbps, MBps, Gbps and GBps?
ISPs sell broadband in Mbps (megabits per second). File-download speeds in your browser or operating system are usually shown in MB/s (megabytes per second). One byte equals 8 bits, so divide Mbps by 8 to get MB/s. A 1 Gbps connection (1000 Mbps) downloads at about 125 MB/s. A 100 Mbps connection downloads at about 12.5 MB/s. This is why downloading a 1 GB file on a 100 Mbps connection takes around 80 seconds, not 10 — the units are different.
Why is my upload speed so much lower than my download speed?
Most UK consumer broadband packages are intentionally asymmetric, because households historically downloaded much more than they uploaded. FTTC packages cap upload at around 10–20 Mbps. Virgin Media cable caps upload at 50 Mbps even on its 1 Gbps tier. Full-fibre packages from BT/Sky/TalkTalk give 100–110 Mbps upload on the 900 Mbps tier. Only fully symmetric ISPs — Hyperoptic, Community Fibre, Gigaclear, Zen on FTTP, Vodafone CityFibre — give upload speed equal to download speed.
Does this test work on mobile data?
Yes — the test runs in any modern browser on any device, including iPhones and Android phones on 4G or 5G mobile data. On 4G/5G expect highly variable results depending on signal strength and cell congestion. For meaningful readings, run the test 3–5 times across the day in the room you typically use, and use the median rather than the best single result.
How often should I run a broadband speed test?
Test once a month under normal conditions to establish your baseline. Re-test if you notice video calls stuttering, streams buffering, or game lag — that confirms whether the problem is your broadband (every test slow), your wifi (wired test fine, wifi slow), or one specific service (test fine, only Netflix slow). If you’re using a result for an ISP complaint, run three or four tests across different times of day on wired ethernet for the strongest evidence.
What’s the fastest UK broadband I can get?
As of 2026 the fastest residential UK broadband is Community Fibre 3 Gbps (London-only, symmetric), Vodafone Full Fibre 2 Gig (CityFibre footprint, symmetric), and Virgin Media Gig2 (2 Gbps download, 100 Mbps upload). Most laptops and phones cap at 1 Gbps over their network port and over wifi, so testing speeds above 1 Gbps requires a 2.5 GbE or 10 GbE wired connection and a router that supports those speeds.
