Hi Bridget,
Thanks for reaching out. The figure you were quoted does sound unusually high, so I completely understand your concern. A standard return transfer between Heathrow and your home should be far less than £700, even with a premium service. It’s possible there was a mix-up in the details (such as dates, vehicle type, or number of passengers).
I’d recommend double-checking the exact pickup location and requirements with the team, as prices can vary depending on distance and vehicle size. If it’s just a straightforward return, it should come out much more reasonable.
Hope that clears things up a little, and I’m sure the office will be able to confirm the correct rate for you.
