Is there bus from Heathrow to Gatwick?

I am going to spend couple of days in London due to a business trip. Afterwards, I am planning a quick getaway to Gatwick. I was thinking about the transportation options from the airport Heathrow to Gatwick. Can someone give me a tip? Is there bus from Heathrow to Gatwick? Thank you!

Yes, there is a frequent bus and it is the most popular option connecting Heathrow and Gatwick providing a near 24x7 service between Heathrow and Gatwick airports. There is no direct train transfer between Heathrow and Gatwick. It would be the best to buy your bus ticket in advance. You have to specify an exact transfer time reserving you a seat.
