Some rates GBP ==>THB
All taken within 2 hours, except Heathrow.
XE mid market: 39.5072
Heathrow T2: 31.77.
BKK Airport : 36.67
BKK Airport rail link. 39.05
Vasu 39.2 (website data, not checked in person).
Transferwise: 39.5229, with fee. The fee was equivalent to - 0.25 baht on £550
Obviously both airports have terrible rates, particularly ThiefRow.
On my last trip, the best offer at BKK Airport rail link was losing approx 0.4% from mid market, which was very good. This year it was nearer 1.14%. TransferWise has the edge.

39,35 at the main SuperRich offices. Note that I also saw that their new office corner of Silom beside THAI and near Arena offers same best rate as the old HQ besides BigC opposite World Trade. Was thronged full of Chinese-or chnese looking aseans.
