The big picture: the UK telecoms market is quietly getting better
To put the numbers in context, Ofcom's quarterly complaints league table is one of the most useful tools UK households have when shortlisting a broadband or mobile provider. It strips out raw volume (which always favours small providers) and instead expresses complaints as a rate per 100,000 customers, making BT's millions of homes directly comparable with a smaller challenger.
Step back, and the long-run trend is striking. Broadband complaints peaked at around 40 per 100,000 in Q1 2011 and now sit in the single digits. Landline peaked at 42 per 100,000 in Q4 2010 and has fallen to 3 today. Pay-monthly mobile (Ofcom's series begins in Q1 2013 at an industry average of 12) has trended down to around 3 today. That is what a maturing, competitive market looks like, and it dovetails neatly with the infrastructure picture set out in our Connected Nations 2025 analysis.

Note: NOW Broadband has been removed from this category from Q3 2025 onwards after four consecutive quarters with a market share below the 1.5% inclusion threshold. TalkTalk and Vodafone results are inside Ofcom's comparability group (less than 1 per 100,000 apart).
Three-quarter view: who is improving, who is slipping
What this means for you
If you are on Vodafone or TalkTalk broadband and out of contract, this is the second consecutive quarter both have been at the bottom of the league table. Most customers will not see issues, but the odds of escalating a fault to Ofcom are roughly twice as high as on Plusnet or Virgin Media. Practical next steps:
- Run a baseline speed test on your current line at ukspeedtest.co.uk so you have evidence if you need to claim faults.
- Work out the speed you actually need using rightspeed.co.uk or our speed guide.
- Compare live deals at your postcode on our postcode comparison tool. Most UK addresses now have at least one full-fibre option, and switching to a low-complaint provider like Plusnet or Virgin Media costs nothing.
- Switch in one step using One Touch Switch. No phone calls to your old provider, compensation applies automatically if anything slips, and most switches complete in 2 to 14 working days.
- Out of contract? You are very likely paying too much. Industry research consistently finds that a substantial share of UK broadband customers are out of contract and overpaying compared with new-joiner pricing. Switching to an in-contract deal at the same speed typically delivers a meaningful annual saving; see our live postcode comparison for the actual saving available at your address.

What this means for you
The wider context matters here. Across the UK, traditional copper landlines are being retired and replaced with Digital Voice services that run over the broadband connection. Many landline complaints sit at the seam of that migration: faults, provisioning delays, or confusion at the point of switch.
- If you barely use your landline, you may not need one at all. Many broadband-only deals are meaningfully cheaper. See our postcode comparison to filter for broadband-only.
- If you do use your landline, read our explainer on Digital Voice and what happens to your landline so you understand the transition before you switch.
- If you have an EE or NOW landline and have been waiting on a switch or a fault, you are within your rights to escalate. From 8 April 2026, Ofcom's strengthened rules let you take an unresolved complaint to an Alternative Dispute Resolution scheme (Communications Ombudsman or CISAS) after just six weeks instead of eight.
- Utility Warehouse, Sky and Virgin Media all sit comfortably below the industry average and are sensible shortlists if landline reliability matters to you. Browse our full ISP directory for live consumer review scores.
Pay-monthly mobile: O2 stands alone, and contract pricing is why

|---|---|---|---|
| EE | 1 | Joint-lowest | - |
| Tesco Mobile | 1 | Joint-lowest | - |
| Three | 1 | Joint-lowest | - |
| Vodafone | 2 | Below avg | - |
| iD Mobile | 3 | At avg | Complaint handling |
| Industry average | 3 | - | - |
| Sky Mobile | 5 | Above avg | Complaint handling |
| O2 | 7 | Highest | Contracts (35%) |
Three-quarter view: the autumn 2025 O2 spike in context
“It is disappointing to see an increase in customers complaints during this quarter, especially following a sustained period of decreases. However, a main driver of these complaints appears to be unexpected mid-contract price rise announcements for some mobile customers in the Autumn of 2025.”
What this means for you
If you are an O2 customer affected by an autumn 2025 mid-contract price rise, you may have a route out. Under Ofcom's January 2025 transparency rules, any mid-contract price rise must be disclosed in pounds and pence at point of sale. If your provider materially exceeded what you were originally told, you may be able to leave penalty-free.
- Step 1: Contact O2 in writing and ask for written confirmation of the original price-rise terms. Read our 2026 in-contract price rises guide for a template letter.
- Step 2: If O2 refuses, escalate to Communications Ombudsman. From 8 April 2026, you can do this after just six weeks instead of eight.
- Step 3: Even if you stay with O2, comparing pay-monthly SIM-only deals takes five minutes. EE, Tesco Mobile and Three all sit at the joint-lowest complaint rate and offer competitive SIM-only pricing.
- Important context: 3 complaints per 100,000 is the industry average for mobile. That is roughly half the broadband rate. Ofcom's consumer experience tracking consistently shows high satisfaction in UK mobile services.
Pay-TV: EE TV continues to draw the most heat; TalkTalk is the calmest
| Provider | Per 100k | Position | Main reason |
|---|---|---|---|
| TalkTalk | 2 | Lowest | - |
| Sky | 3 | At avg | - |
| Virgin Media | 3 | At avg | - |
| Industry average | 3 | - | - |
| EE TV | 5 | Highest | Changing provider (32%) |
What this means for you
For households shopping for a bundle, the implication is encouraging: three of the four major UK pay-TV providers sit at or below the industry average. Switching pay-TV provider can be a faff (kit, accounts, app re-installs), so the rankings matter even more than for broadband.
- Best-rated bundles: Check our live broadband and TV deals for the latest pricing across Sky, Virgin Media and TalkTalk.
- If you are with EE TV and frustrated by switching difficulties, the 32% switching-related complaint rate suggests you are not alone. Document every interaction in writing, then escalate to Communications Ombudsman if unresolved after six weeks (new rule from 8 April 2026).
- Streaming as an alternative: More UK households are mixing a small Sky or Virgin Media bundle with streaming subscriptions (Netflix, Disney+, Apple TV+, Now). Our insights hub covers the latest UK trends.
Why providers attract complaints: the reasons behind the rankings
Ofcom publishes the leading reason-for-complaint for each provider whose complaint rate is above the industry average. This is genuinely useful for switchers, because it tells you which providers struggle with which kinds of problems. Here is the Q4 2025 snapshot:
| Sector | Provider | Leading reason | Share |
|---|---|---|---|
| Broadband | Vodafone | Faults, service and provisioning | 52% |
| TalkTalk | Faults, service and provisioning | Leading reason | |
| Landline | EE | Switching providers | 33% |
| NOW Broadband | Faults, service and provisioning | 50% | |
| Mobile | O2 | Contract issues | 35% |
| Pay-TV | EE TV | Problems with changing provider | 32% |
The pattern is informative. EE and EE TV both struggle most with switching, which is fixable and worth raising with the regulator. Vodafone and NOW Broadband both struggle most with faults, which is harder to fix overnight. O2's issue is contract pricing, which is squarely a regulatory and disclosure question. And nobody in Q4 was flagged primarily on billing, which is a meaningful improvement on five years ago.
Comparability groups: when two providers really are the same
Ofcom's methodology rounds complaint rates to the nearest whole number per 100,000 customers, and where two or more providers are less than 1 per 100,000 apart, Ofcom treats them as comparable rather than ranking them. This stops the league table from making spurious distinctions. The Q4 2025 comparability groups are:
- Broadband (four comparability groups):
- Virgin Media and Plusnet (joint-lowest)
- Sky, Industry Average and BT
- Industry Average, BT and EE
- TalkTalk and Vodafone (joint-highest)
- Landline (three comparability groups):
- Virgin Media, Sky and Vodafone (low cluster)
- Vodafone and Industry Average
- BT, Plusnet, TalkTalk, EE and NOW Broadband (top cluster)
- Pay-monthly mobile (three comparability groups):
- Three, EE and Tesco Mobile (joint-lowest)
- Tesco Mobile and Vodafone
- Vodafone, Industry Average and iD Mobile
- Pay-TV (two comparability groups):
- TalkTalk, Sky and Virgin Media (low cluster)
- Sky, Virgin Media and Industry Average
Read this as: if a comparability group includes the industry average, the named providers are statistically indistinguishable from the average, which is a reassuring place to be. And if a low cluster sits comfortably below the industry average (for example, the landline low cluster of Virgin Media, Sky and Vodafone at 2 to 3 per 100,000 versus an industry average of 3), those providers are demonstrably ahead of the pack on that service.

What this means for UK customers overall: the story behind the numbers
Behind the numbers, the story for UK households is genuinely upbeat. Ofcom's consumer experience tracking consistently shows broadband satisfaction in the low to mid 80s and mobile in the high 80s. Most of us, most of the time, get a service that works.
The Q4 2025 mobile spike is best read as regulation working as intended: Ofcom's January 2025 pounds-and-pence price-rise rules made it easy for customers to spot when a provider's mid-contract increase looked larger than originally disclosed. Customers complained. Ofcom captured the data, named O2, and published a quotable explanation. That is what a healthy regulator looks like.
Three positive trends are worth highlighting:
- Full-fibre is reaching scale. Per the Connected Nations 2025 report, UK full-fibre availability reached 78% of residential premises by July 2025, up from 69% a year earlier. This is the single biggest infrastructure shift in UK telecoms in 20 years, and it explains why broadband complaints continue to fall.
- The complaints process is faster. From 8 April 2026, customers can escalate an unresolved complaint to an Alternative Dispute Resolution scheme after six weeks instead of eight. This is a meaningful tightening of consumer rights.
- Switching is friction-free. One Touch Switch means you contact only your new provider, who handles the migration end-to-end. Compensation applies automatically if anything slips. No phone calls. Most switches complete in 2 to 14 working days.
How to act on this data: a five-minute switch plan
- Check your renewal date on your latest bill or in your provider's app.
- Test your current line speed at ukspeedtest.co.uk so you know what you are really getting.
- Work out the speed you actually need using rightspeed.co.uk or our speed guide.
- Compare live deals at your postcode on our comparison page. Filter by full fibre, contract length or price.
- Sign up with the new provider. They activate One Touch Switch and notify your old provider for you. Read our switch checklist and engineer-visit checklist if you have an installation booked.

Who received the most Ofcom broadband complaints in Q4 2025?
Vodafone (11 per 100,000) and TalkTalk (10 per 100,000) were the most complained-about UK fixed broadband providers in Q4 2025. Plusnet and Virgin Media were joint-lowest at 5 per 100,000.
Who received the most Ofcom mobile complaints in Q4 2025?
O2, at 7 per 100,000. This is more than double the industry average of 3. Ofcom attributed the spike to O2's autumn 2025 mid-contract price-rise announcement, with 35% of O2's complaints being contract-related.
Which UK telecoms provider had the fewest complaints in Q4 2025?
By service: Plusnet and Virgin Media (broadband, joint-lowest at 5 per 100,000), Utility Warehouse (landline, 1 per 100,000), EE, Tesco Mobile and Three (mobile, joint-lowest at 1 per 100,000), and TalkTalk (pay-TV, 2 per 100,000).
Did UK telecoms complaints go up or down in Q4 2025?
Per Ofcom's official Q4 2025 release, total complaints rose for the first time since 2023. However, broadband and landline both fell quarter-on-quarter, pay-TV was flat, and the rise came entirely from pay-monthly mobile, specifically from O2.
Why did O2 get so many complaints in Q4 2025?
35% of O2's Q4 2025 complaints related to contracts. Ofcom attributed the spike to O2's autumn 2025 announcement of larger-than-expected mid-contract price rises. Cristina Luna-Esteban, Ofcom's Director of Consumers and Retail Markets, identified this as the main driver of the quarter's overall increase.
Why is NOW Broadband no longer in the broadband table?
From Q3 2025, NOW was removed from the broadband category after its market share fell below 1.5% for four consecutive quarters. It still appears in the landline table.
How do Q4 2025 numbers compare with the long-run trend?
Broadband complaints peaked at around 40 per 100,000 in Q1 2011 and are now in single digits. Landline peaked at 42 per 100,000 in Q4 2010 and now sits at 3. Pay-monthly mobile (Ofcom's tracked series begins in Q1 2013 at an industry average of 12) has trended down to around 3 today. Long-run, all four sectors have improved dramatically.
What should I do if I am unhappy with my provider?
Complain in writing to your provider. If unresolved after eight weeks (or six weeks from 8 April 2026 under Ofcom's strengthened rules), escalate to Communications Ombudsman or CISAS. If you are out of contract, consider switching using One Touch Switch.
Methodology and caveats
Ofcom's quarterly report covers only complaints received directly by Ofcom. It does not include complaints sent only to the provider, to the ISPA, or to an Alternative Dispute Resolution scheme (Communications Ombudsman, CISAS). It only includes providers with at least 1.5% market share in each category. Volumes are expressed per 100,000 residential customers to allow fair comparison across providers of different sizes.
Where the measured difference between providers is less than 1 complaint per 100,000, Ofcom treats their results as comparable (see the comparability groups section above).
