Heathrow to Tunbridge Wells

Hi!

So I'll be arriving at Heathrow on April 4 - I haven't booked my air fare, but since I'm coming from the U.S., it will be morning I imagine

The only way to get from Heathrow to TW by public transport is the Heathrow Express to Paddington Station, then a train to TW?

I may just book a car service as it's much more convenient....but it's also a lot more expensive

Thank you!

EDIT:

As suggested below, I'm going to try and make a flight from Gatwick - which I honestly hadn't considered ...my bad
