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.

Run the Pulse UK speed test

Pulse measures download speed, latency, and jitter in your browser. It does not measure upload speed. For upload, use your provider’s tests or see our upload scope guide.

Compare broadband deals when your line is too small for what you do: BroadbandSwitch.uk, SearchSwitchSave.com, FibreSwitch.com.

UK rights and switching: start with Ofcom’s broadband guidance for personalised speed estimates, switching, and complaints.

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.
