Hector I'm in the UK atm and have noticed as usual, how lucky we are with the cost of living in Thailand.
Some typical expenses for comparison :-
Rent UK B 40,000 pm Thailand B 10,000 (3 bed 2 bath bungalow)
Electricity UK B 8,400 pm Th B 1,500 pm
Council tax UK B 6,000 pm Th B 30 pm (dustbin emptying twice a week !)
Diesel UK B 70 per litre Th B 34
Gas UK B 4,000 pm Th B 70 pm
Water UK B 2,000 pm Th B 100 pm
Dining out UK B 1,200 Th B 500B (for 2, excl. alcohol) (restaurant not street food)
Beer UK B 160 Th B 60 (cheapest)
Car servicing and repairs - UK a dramatic multiple of Th costs
It's true that some items of Falang food and wine are more expensive in Thailand BUT overall, costs in Thailand are much lower.
(Ken - re. Cheddar cheese - Makro have 2 kg for B700-800, (it's not the most tasty maybe but it's OK).
