ISPreview has today published our latest biannual study of how the United Kingdom’s broadband download and upload speeds have changed across the fastest nationally available fixed line ISPs, mobile network operators and Starlink<\/a> (satellite<\/a>) services since the end of 2024. But this time we’ve made some changes to the structure of our top lists.<\/p>\n

As usual, the results in this report stem from consumer web-based speed testing and are thus inevitably impacted by a number of factors, such as the rising coverage of faster networks (e.g. full fibre and 5G<\/a>) and the level of take-up by customers. As a result it helps to understand any key changes in network deployments over the same sort of period, which is shown below using Ofcom’s Spring 2025 Connected Nations<\/strong><\/a> data.<\/p>\n

NOTE:<\/strong> The term \u201cgigabit-capable<\/em>\u201d on fixed lines refers to the combined coverage of Full Fibre (FTTP<\/a>\/B) and Hybrid Fibre Coax (HFC \/ Virgin Media<\/a>) networks. Ofcom<\/a> predicts the UK will achieve gigabit coverage of between 97-98% by May 2027 (here<\/a>).<\/div>\n\n\n\n\n\n\n\n\n\n\n

5G<\/a> Outside Premises<\/td>\n62-85%<\/td>\n61-79%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

In terms of fixed line broadband lines, the primary coverage improvements have continued to come from Fibre-to-the-Premises<\/strong> (FTTP<\/a>) networks (Summary of UK Full Fibre Builds<\/strong><\/a>). This is despite ongoing market pressures (i.e. rising build costs, high interest rates, fierce competition etc.) continuing to result in many alternative operators (altnets) suffering job losses and a slowdown in their deployment plans.<\/p>\n

Full fibre networks are now also the sole driving force behind the rise in gigabit-capable coverage, which continues to be predominantly fuelled by commercial roll-outs in urban areas. Speaking of which, gigabit coverage passed the Government’s first target (85%) under their \u00a35bn Project Gigabit<\/strong><\/a> programme earlier this year (this focuses on the final c.10-20% of rural premises) and is now aiming to hit c.99% coverage by 2032 (delayed from the original 2030 target – here<\/a>).<\/p>\n

Finally, in terms of mobile networks, there have been further improvements in 4G<\/a> and 5G (mobile broadband) coverage. For example, the industry-led \u00a31bn Shared Rural Network<\/strong><\/a> (SRN) project has made a little progress on boosting geographic 4G<\/a> coverage and still aims to cover 95% of the UK \u2013 from at least one operator (84% from all operators combined) \u2013 by the end of 2025.<\/span><\/span><\/p>\n

NOTE:<\/strong> Web-based speedtests can be affected by various issues, such as slow Wi-Fi, limitations of the tester itself, local network congestion and package choice (a lot of people will pick a slower and cheaper plan, even with 1Gbps available). The following results are thus only good for observing general market change over time and MUST NOT be taken as a reflection of ISP capability.<\/div>\n

Fastest Major Fixed Broadband ISPs (H1 2025 vs H2 2024)<\/strong><\/span><\/h3>\n

The data in this report has been gathered from Thinkbroadband<\/a>\u2019s independent speedtest database (inc. ISPreview\u2019s Broadband Speedtest<\/a><\/strong>). The table below only includes the largest and most established independent ISPs with strong national availability, but there is a separate table for smaller providers directly below \u2013 these are difficult to include because such providers don’t produce much test data (fewer users).<\/p>\n

Naturally, there are caveats to consider with speedtest based studies like this, not least because the results tend to be more reflective of take-up than network availability. For example, some ISPs may have a much larger proportion of customers on slower copper-based (ADSL<\/a> or FTTC<\/a>) lines, which can weigh against anybody on faster FTTP packages with the same provider (i.e. pulling average speeds down). The opposite can also be true.<\/p>\n

However, the big change this time is that we’ve stopped doing a dedicated table for altnets, which is partly because some operators are wholesale-only (i.e. they lack a dedicated ISP for judging performance) and many other ISPs are now working with more than one underlying network operator. This has made doing an altnets-only table quite tedious and we’ve instead produced a second table that only includes the top 20 smaller ISPs (these do not require national availability and exclude those listed in the top 8 below).<\/p>\n

NOTE:<\/strong> The top 10% is the speed experienced by the fastest users on each ISP (below in brackets). The results are averages (median) in Megabits per second (Mbps). The H2 2024 data was processed at the end of November 2024 and the latest H1 2025 data in late April 2025 (a month earlier than usual due to external factors).<\/div>\n

Overall, the average download speed<\/strong> of the top national providers was 90.12Mbps (up from 76.56Mbps) and the average upload speed<\/strong> hit 21.61Mbps (up from 15.88Mbps). The picture this time around is one of very mixed changes, with Zen Internet<\/a> and EE<\/a> showing big gains in download performance since the end of 2024, while for upload speeds the biggest gains came from Zen Internet<\/a>, EE<\/a> and Plusnet<\/a>.<\/p>\n

Now flick over to page 2 to continue this summary and see how the fastest satellite<\/a> (starlink<\/a>), mobile operators and smaller ISPs all performed.<\/p>\n

<\/p>\n

We suspect most of the improvements mentioned in the prior paragraph will be due to customers upgrading to Fibre-to-the-Premises (FTTP) based packages from slower ADSL<\/a> and hybrid fibre (FTTC<\/a> \/ SOGEA) based ones – all three providers have plenty of customers on legacy connections left to convert.<\/p>\n

Otherwise, Vodafone<\/a> saw a small decline in download performance, while TalkTalk<\/a> saw bigger declines in both download and upload performance. The latter is most likely due to weighting changes as TalkTalk<\/a> lost around 400,000 customers last year (leaving them on 3.2 million), which will have impacted the structure of their base and splits between different connection types.<\/p>\n

Fastest 20 Smaller Broadband ISPs (H1 2025 vs H2 2024)<\/strong><\/span><\/h3>\n

As mentioned above, the following table reflects a top list of 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.<\/p>\n

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 often have a lower portion of users (sometimes none at all) on older copper-based connections (ADSL<\/a>, FTTC<\/a> etc.). But there are some exceptions (e.g. some highly rated ISPs that have been around a long time may suffer in this table due to the impact of legacy users on slower lines).<\/p>\n

NOTE:<\/strong> This list excludes major ISPs (those listed above), dedicated business\/school providers, satellite<\/a> and mobile operators.<\/div>\n

Overall, the average speeds shown above are significantly faster than those of the market’s largest ISPs, which isn’t surprising as a lot of the smaller players will be using modern alternative full fibre networks that have managed to pull customers away from often slower packages and older connection technologies on the biggest providers.<\/p>\n

The catch is that smaller providers produce a smaller data sample, which means that these results will fluctuate more over time. Internet providers are also more likely to both dip into and out of the above list, between updates, due to many of them only just being able to produce the minimum required level of test data.<\/p>\n

Satellites<\/strong><\/span><\/h3>\n

We’ve also been keeping track of the results for SpaceX’s satellite based Starlink<\/a> broadband service. Sadly, not enough data exists to include other satellite platforms or providers, but that may change in the future. Otherwise, Starlink’s download performance appears to have risen during the first half of 2025 and it’s a similar story for their upload performance.<\/p>\n

The Fastest Mobile Operators<\/strong><\/span><\/h3>\n

Mobile performance remains a difficult network technology to study because end-users are always moving through different areas (indoor, outdoor and underground), using different devices with different capabilities and the surrounding environment is ever changeable (weather, trees, buildings etc.). All of this can impact signal quality and that’s before we consider any differences in network (backhaul) capacity or spectrum usage between locations.<\/p>\n

Suffice to say that studies of mobile broadband speed are inherently open to variation, but the top networks often tend to be those with a combination of the best 4G or 5G coverage, a good amount of radio spectrum and the most advanced technologies.<\/p>\n

Overall, the average download speed<\/strong> of the four primary mobile operators was 26.42Mbps (down from 28.1Mbps in H2 2024) and the average upload speed<\/strong> hit 5.25Mbps (up slightly from 5.17Mbps). The big change this time around seems to be that near 26% loss of downstream performance at Vodafone<\/a>, although we have seen big swings with mobile operators like this before and suspect it’s not the start of a new trend.<\/p>\n

The market for 5G services in the UK is now started to reach a degree of maturity, with swings of c.5-10% in one direction or the other are not uncommon between biannual updates. However, the most interesting one to watch going forward will be how the results change as Three UK<\/a> and Vodafone<\/a> begin the long-winded process of network integration, although for now we’ll continue to list them as separate brands.<\/p>\n

Take note that existing 5G networks also remain hobbled by some issues of limited coverage and legacy 4G services, although ongoing expansion Standalone 5G (SA) networks is starting to change that. In addition, Ofcom<\/a>’s plan to auction off more 5G spectrum in the mmW bands – 26GHz and 40GHz – in the very near future is another event to watch, although its impacts may be limited to busy urban areas and events (device support is another factor).<\/p>\n","protected":false},"excerpt":{"rendered":"
