https://www.thinkbroadband.com/speedtest if you are connected via Ethernet and nothing else is using the connection and the multiple test is below the guaranteed figure then its time to raise questions with the provider. Along with numerous other sites.

Of course there are scenarios where site A is slow and site B is fast, or there are slow speeds for a very short period each on say Friday evenings every other week.

Remember the new rules only have been around for a few days and there is a 12 month implementation period. How it is implemented will vary and how the support teams cope will vary.

If that is the case how should customers ascertain whether the service they are getting is performing properly?

Does it work? Is it doing everything you want/need it to? Does it feel appropriately snappy/responsive as it has historically?

Streaming good, no/minimal buffering and appropriate resolution unless of course your service has never supported higher resolutions?

Gaming smooth, no packet loss, rubber-banding?

Voice / video calls working as they have been?

Job done.

It is when things are not as you would like, that conclusive evidence, such as a multistream speed test from this website, that the service is poor could well be very helpful. You can then say please fix the service or let me out of the contract.

Then if the ISP is doing their job they run the test from their router. All good.

Plusnet said that BT have started to send out suitable routers, they themselves have not got that far yet.

Is this going to make it more difficult for people to use their own routers rather than the one supplied by the ISP?

As in 'you need to use our router so that we can run the tests' yes this might be an issue.

Or the old classic of 'there may be a charge if we send an engineer to test the line and the fault is found to be in your hardware, extension wiring etc' - at which point if someone worries and says no to engineer visit to check in house wiring the 30 day period probably resets.

As with all these moves to 'improve things' it is around the average consumer and not the many edge cases
