Having worked at London Mil in a previous life...
R Sole, they'll have an electronic flt strip with your details on it if you've filed a flt plan and addressed it to them. As for the rest of that paragraph, sorry can't comment.
London Mil uses the NATS radar heads and the Great Dunn Fell radar head does tend to produce a lot of clutter around the Teesside area.
Calling "Limited traffic information from all around due to high traffic density" an old chestnut is slightly unfair when applied to the Vale of York. A controller trying to get you through there under RAS is, on a bad day, trying to weave you through up to 40 VFR radar contacts playing between the surface and FL200, not to mention the radar clutter, which may be gliders, Leeming outbounds and stuff in the southern MDA. Mil controllers don't have the option of "just giving a RIS" if it gets a bit hard. You can only stop giving RAS under extreme conditions so if that's what you asked for, that's generally what you'll get. Some airfield controllers will try and convince you that you can't give RAS in their airspace because it's too busy, but that's rubbish. It just means that they don't understand the rules that they're applying fully.
Agree totally with norvenmonkey about handover phraseology
