Being SATCO Northolt, I can confirm the comments made by ATCO Two. What's more, whilst in the Northolt Radar Manoevring Area (NRMA), military controllers may allow SVFR traffic to take visual seperation on all Northolt IFR traffic. In other words, you can be handled as if you are SVFR within Class D airspace.
Confused? - Join the club.
PS. Regarding your RT failure question, if you went to Gutteridge and held there squawking any of the emergency codes we may get quite twitchy.
