I quoted price of single individual only. Price also depends on age. You can just call them and they will be happy to send you a quote with all the benefits and hospital list etc.
It deppends what expensive is as everyone's budget is a little different. Anyways I have been searching for insurance as well and have found the cheapest one being Takaful Emarat having cost 1750 for married females and 650 for non working dependants, The cheap price comes because of specialists consultation based only on GP's referral, But their are other options such as NGI, DNIR, Salama, AXA, ASNIC, Mednet which come in the range 3500 to around 5000 being their minimum or medium package. This rate is for married female; dont know about the child, will probably be a lot less. You can also go for better options but like is said budget depends. U can visit website like bayzat or insureme; they can give you quotes from different companies and can help with you with whole process of issuance of the policy, Dealing with companies yourself is a headache! Hope it helps.
