You get nominally 240 V RMS, actually it varies from -320 to +320V every second but ignoring that, you are not guaranteed 240V. The target is 240V +/- 10% but can easily be as high as 265V or as low as 220V during normal operation. During busy periods you get brownouts and sometimes you get complete cutouts.
Perhaps you're a bit spoilt where you live but there are plenty of places in the world where electricity cuts out several times a day and always browns out during peak periods.

Living in the UK as you do else you wouldn't be a VM customer, I've never experienced a brownout. Last power cut was in the early 70's during the miners strike and the 3 day week.
You get the point though.
VM aren't supplying internet in some backwater 3rd world country are they?
If they could supply 90% of the rated speed and stick to it, that would be absolutely fine, heck even 80% all the time would be acceptable.
Between 5%-15% isn't.

In any case, poor example aside, every consumer ISP out there does the "up to" thing.

It was slightly contrived, but it makes the point though.
