Speedtest

Please take note that this test can cope with both current and next generation Gigabit broadband speeds (up to around 1,000Mbps), although the dynamic nature of Internet connectivity means that the results may not always be 100% accurate. Tests conducted via WiFi may also produce a slower result, especially if others are using your network.

Results - Big UK Home Broadband ISPs

The first set of results below only include the largest independent UK ISPs with a wide national availability, which is primarily because smaller and often faster altnet providers (Gigaclear, B4RN, Hyperoptic etc.) aren't yet available to the majority of people and others didn't produce enough test data to be included.

NOTE: The top 10% result below represents the speeds experienced by the fastest 10% of customers at each ISP (usually those with the best connections / fastest packages).

1.	Zen Internet	46.3Mbps	19.9Mbps	132.66%
2.	Virgin Media	33.7Mbps	31.2Mbps	8.01%

7.	Plusnet	13.2Mbps	9.2Mbps	43.48%
8.	TalkTalk	9.3Mbps	10.8Mbps	-13.89%

Overall, the average download speed of the top national providers was 90.12Mbps (up from 76.56Mbps) and the average upload speed hit 21.61Mbps (up from 15.88Mbps).

Results - Smaller ISPs

The results below cover the fastest smaller providers (excluding those major providers listed above and some others), which also includes some large-ish providers that may not have strong national availability due to the limited coverage of their underlying network(s). This is intended to provide some useful context against the biggest and most widely available market players above.

The table below is ordered by median download speed, but for extra context we've also included a figure for upload performance in brackets. Most of the providers in this list are faster than the major players because they're often connected to alternative networks with faster entry-level packages and will have a lower portion of users (sometimes none at all) on older copper-based connections (ADSL, FTTC etc.).

However, there are some exceptions to the above, such as some highly rated ISPs that have been around a long time - these may suffer in this table due to the impact of legacy users on slower lines.

Results - UK Mobile Broadband Operators

These results reflect the four primary Mobile Broadband (4G and 5G) operators. Mobile services are subject to the daily movements and radically different hardware choices (Smartphones etc.) of their end-users, which makes it difficult to establish a reliable picture of performance.

1.	Three UK	36.1Mbps (268.1Mbps)	38.1Mbps (264.4Mbps)	-5.25%
3.	EE	31.5Mbps (124.3Mbps)	30.8Mbps (106.1Mbps)	2.27%
2.	Vodafone	20.6Mbps (98.7Mbps)	27.7Mbps (216.3Mbps)	-25.63%

4.	O2	3Mbps (17.3Mbps)	2.5Mbps (19.5Mbps)	20%

Overall, the average download speed of the four primary mobile operators was 26.42Mbps (down from 28.1Mbps in H2 2024) and the average upload speed hit 5.25Mbps (up slightly from 5.17Mbps).

Disclaimer: Please take average (median) speeds with a big pinch of salt. Every home is different and performance can be affected by all sorts of issues, many of which are beyond the provider's ability to control (e.g. tests conducted via slower smartphone vs faster desktop computers, slow wifi, poor home wiring etc.), thus we do not consider the above data to be a reliable barometer for individual user connectivity, but it can help to highlight general changes in the market.

NOTE: Data for H1 (first half of the year) is usually collected during the end of May (this year it was April), while data for H2 (second half of the year) is collected during the end of November.
