Anyone who charges more than 150TL £60 to do this service is charging too high in my opinion, it is so easy to do it yourself, the only bit that is slightly difficult is tracking around the different offices, but these are only formalities of getting a stamp or a piece of paper/book.If it is a renewal it is even easier as you use your exsisting Blue book so no PTT run. We did the renewal process in 3 hours and in truth it could have been quicker but we had our 2 year old with us. One bit of advice I will give is you can only apply for as many years your current UK passport is valid, so don't apply for 3 years if you only have 1 year left on your passport as you will only get a year they will still take payment for the 3 years and then you will need to sort a refund or keep your payment on file for your next renewal.
