Actually, I would have thought that the formal notification of the airspace in the AIP would/should make it clear, even if it is hard work going through all the co-ordinates and "except that airspace contained within.." etc. After all, that is the definitive authority.

No I can't; all I can say is that once upon a time before it was re-organised in about 1976, the LTMA was the equivalent of Class E below 5,000ft irrespective of its base level which in some places was as low as 1,500ft (eg between the Heathrow and Gatwick CTRs) whilst the Heathrow CTR was 'Rule 22' (mandatory IFR) from SFC to FL110
