London Information cant be over recommended - they are always happy to talk to low hours pilots and are a wealth of knowledge and support
Finally, if you dont have it already, consider apps such as Sky Demon. Not only will they prevent you busting airspace, but they give you all possible frequencies on the planning page plus the ability to find a frequency in the air by simply touching and holding the area of airspace
Safe flying
