Hmmm on a recent trip back to the UK I was shocked how much prices markedly went up in the supermarket their since my previous visit only 8 months before. But on the other hand when you look at prices here in Turkey they are just as shocking for some items. For instance a kilo of beef mince in Turkey costs around £10 in the UK a kilo of steak mince from Tesco is around the £5 mark, granted you can buy cheaper (fatty) mince in UK but this is a par product look. Cost of living wise I would say Turkeys overall cost of living has gone down this year especially with the resident visa costs now being drastically reduced. But on a product to product comparison there are clearly disadvantages on the Turkish side. Heres my list of what is more expensive in Turkey compared to UK.
FUEL (Petrol, Deisel, LPG)
MEAT
SPIRITS
WINE
ENGLISH PRODUCTS (PORK SHOP RANGE tin of baked beans 80p)
VEHICLES (PURCHASE)
VEHICLES ANNUAL TAX (EXTREME EXAMPLE BEING FOR A RANGE ROVER 4.6 NEW IT WILL COST OVER £6000 A YEAR!!!)
Taking above into account your other cost of living items compared are cheaper (fruit & veg, property etc,) so I guess they are roughly the same on pros and cons.Of course if you compared on sunshine, customer service, lifestyle, Turkey wins hands down!
