I recomend using both 1;250,000 and 1;500,000. but would back it up with a PDA using seeyou mobile. A hp312 travel mate has a good screen and battery life and seeyou will bark at you if you go near CAS.
Gliderpilots have been using this stuf for 10 years or more and seldom infringe airspace as a result. If you want to fly without gps i would recomend practicing well away from airspace and once you can thread your plane through narrow gaps ( 2nm) in bland countyrside at low level before going anywhere near north london
strongly recomend reading "ontrack" to see how even expreinced ppls infringe in this area. VOR tracking is useless and one needs to be able to re route at short notice if ATC do not give clearances you might hope for. the PDA can give help in a way that no other device can when the presure comes on in poor vis or low sun.
The boundaries of airspace are not designed to help us navigate clear of it and the area round EGSS is notoriously difficult ,even for very experienced pilots.

ps with the HP312 and seeyou software you can download your flight and see if you went where you thought you went and asess how good your nav really is. Instructors would also be able to monitor solo pilots tracks and see infringements or gross errors
