It is already here. Trials have been taking place in Scotland and 
Winchester and possibly elsewhere by Southern/Scottish Electric. 
There must be amateurs in Winchester who are affected, the lack of 
any comments from there seems worrying.

Most of the studies have concentrated on interference levels in the 
immediate locality, ie adjacent houses. Much harder to quantify is 
the increase in general background noise levels at greater distances. 
I, like I guess many, suffer from increased noise levels on 80m in 
the evening which may or may not be related. It is extremely 
difficult to associate this type of noise with any particular 
interference source, so the promise that individual interference 
cases will be dealt with is hardly any comfort.

Any amateurs in Winchester on here who would care to comment?

The IEE made a submission on this, S664, which contains comments from 
many amateurs including myself and is interesting reading. I don't 
have the direct link, but you should be able to find it at
