What is broadband traffic management?
Who this page is for
Users who wonder if they are being “throttled” and want a factual starting point.
Plain-English definitions
- Traffic management
- Network policies that may prioritise or slow certain categories of traffic according to published rules.
What to read
Start with your provider’s current traffic policy and Ofcom’s consumer materials. Do not rely on forum rumours.
Separate Wi-Fi first
Run fair tests on Ethernet before concluding management is the cause.

Example scenario
You suspect throttling. Ethernet tests at quiet times match the package, but peak tests dip. You read the provider’s policy and raise a ticket with dated results.
FAQ
Is traffic management illegal?
Providers must be clear about applicable policies. Use Ofcom’s guidance on information you should receive.
Where do I find my provider’s policy?
Look for traffic management or open internet information on your provider’s site and in your contract materials.
Is all slowdown traffic management?
No. Wi-Fi, faults, and general congestion also cause slowdowns. Test fairly before assuming policy effects.
Can management affect video but not browsing?
Policies vary by product. Read what your provider publishes for your tier.
What should I ask support if I suspect unfair treatment?
Ask how your product is treated, what transparency you should have been given, and how to raise a complaint.
Does Ofcom define every detail?
Ofcom sets expectations around information and consumer protection. Use their hub for the latest wording.
