Alex, have him look into hiring a private taxi, we've found it to be not that much more expensive and far less hassle than riding the train. I think we usually pay under 40 pounds from Heathrow to Surrey. Well worth it for the door-to-door service, especially for two or more people. A quick internet search shows prices for Aldershot nearer to 55 pounds.
Maybe a bit high if he's traveling alone, but it will save him a lot of brain damage if he's not familiar with navigating the train.
