On Pistonheads a lawyer has posted info about “frustrated contracts”. These are contracts that for some reason beyond the control of either party cannot proceed. The current Covid19 makes this such a scenario. I asked about a planned trip to this year’s Jersey Festival booked by a group of us via Scenic Car Tours. Deposits only paid as the full payment date came after the decision to cancel. The event was cancelled so there was no way the contract/booking could proceed. He replied that it was probably a frustrated contract ( note not definite...lawyer speak). As such there could be a legal course of action available to reclaim monies. A trade organisation changing their mind about refunds would not supersede a law that was in place. So you could push for this option as there is a legal precedent. Whether or not the travel company stays in business is a consideration but any credit notes would be worthless then anyway if they went under.
As for the Jersey trip, I think all of us have opted to reschedule to next year when the event should go ahead. No big money total tied up so a minor gamble.
