How difficult will it be getting to Bradford on Avon, do we need to go to Bath and then arrange for a cab, bus??? Should we book in advance?
There are frequent trains right to the centre of Bradford-on-Avon, but not from Heathrow... Do what you would do to go to Bristol or Bath and make a slight detour en-route.
I would take the Rail Air coach from Heathrow to Reading

Then take a train from Reading to Bradford on Avon

The cheapest tickets are called Advance which must be used on the booked train. Walk-up fares are shown as Off-peak and Anytime tickets.
Thanks so much for both your suggestions. Having never been to England I am clueless! All the help I can get is much appreciated!
