We’ve learned that the most time and cost effective way to get to central London to/from Gatwick is the Gatwick Express train. The cost £41.40 for two people, one way, from Gatwick to Victoria Station. With only 2 stops on the way the entire journey takes about 35-40 minutes. If you take a taxi it will be 1 hour 30 min and cost about £150! The trains are comfortable, mostly clean, and the best way to travel into central London.
