As with UK or Ireland, this depends on the price of your property and when you buy. As a guideline, annual running costs for an average 2/3 bedroom property will be £1,000 – £1,500 per annum. This will include gas, electricity, water, local rates, community fees and insurance.
Your appointed Lawyer will ensure that all services have been connected to a new property, although you may be asked to obtain the necessary direct debit forms from your Portuguese bank.
NB. The cost of living is lower than in the UK and Ireland. A couple with no mortgage could easily live on £200 per week and eat out regularly.
