Hi Jardave,
If you are looking at living with the same standards as in the UK you can live on a monthly expenses of about £600 per month. If you have your own home I assume you do not have to pay rent or mortgage. The biggest expenses would be Food, Electricity, Taxes, Internet and Travel & Meals Out. This does not include paying wages to staff such as gardeners, housekeepers, nannies or schools etc With regards to food, there are many supermarkets which now sell everything you can get in the uk, however the local markets are a lot cheaper and have more variety regarding fruits and vegetables.
