Broadband "Speed Tax": Is your provider failing the evening rush?

ended 18. May 2026

Broadband Genie has analysed 144,509 broadband speed tests to identify the UKs "broadband congestion zones". The areas and providers where Internet speed drops most significantly during the evening window (7pm - 11pm).

While some areas and providers handle the surge well, our data identifies a clear "Speed Tax" for others. Users in Wigan were most effected and out of the widely available providers, Sky and TalkTalk customers saw the biggest drop in download speed.

Key takeaways:

  • South West and Northern Ireland are the worst regions for broadband congestion
  • Scotland is the best region
  • The best town, Newport actually see an 87% speed boost in the evening.

What we're looking for:

We're a broadband comparison service and the experts on all things broadband. We can provide expert commentary on consumer rights and infrastructure.

However, we are specifically looking for the Newspage community to provide:

  • Sky, TalkTalk, and KCOM Customers: Are you noticing a significant drop-off in quality after 7 pm? Does your Netflix buffer or your gaming lag just as you sit down for the evening?
  • Home business owners and remote workers: Is your late night productivity being stalled?
  • Gamers: Does peak-time latency affect your enjoyment and performance?
  • Regional case studies: Residents in the worst-effected areas. Wigan, Galashiels, Harrogate, Exeter and Rochester

Broadband Genie’s analysis of 144,509 speed tests is useful because it quantifies something many users already experience nightly: the evening slowdown is not random, it is structural. Framing it as a “Speed Tax” is effective, but this is less a pricing issue than an infrastructure and capacity planning issue. Peak-time degradation reflects years of uneven investment in backhaul capacity, local network contention, and regional upgrade priorities. Areas seeing sharp drops are often downstream of where networks were built to absorb demand and where they were not. The bigger issue is transparency. Most households buy broadband based on advertised headline speeds, while real-world evening performance can vary significantly by region and network load. Complaints processes cannot solve a capacity problem.

Broadband Genie's 2026 "Speed Tax" report exposes a harsh reality for UK digital infrastructure. Despite national ambitions for gigabit-capable coverage, evening congestion remains a serious bottleneck for thousands. For home business owners in Cornwall, the South West's ranking among the worst regions for congestion is particularly damaging, with the infrastructure routinely failing. These business owners already contend with higher council tax premiums and the country's second-highest water rates, and this "Speed Tax" of lost peak-hour productivity compounds an already costly existence. The evening slowdown goes well beyond streaming issues. Failed video calls and high latency make real-time collaboration far harder than it should be, raising genuine questions about whether the UK's digital ambitions are translating into the reliable, consistent connectivity that modern remote workers actually need.
