Not a simple answer really.
It depends on who you bank with and what type of card you have with your bank, as your own UK bank may well charge even though the Turkish one may not.
You need to look at the terms and conditions of your bank.
Some Turkish banks now charge to draw sterling. I've not drawn sterling for a while but I think TEB still make no charge.
Similar with drawing Lira, it depends on what bank and card you are using.
We have used a Starling Bank card for the last few years which makes no additional charge themselves, but the ATM machine may. It's you're using one of these cards always draw in Lira and have it charge in Lira (not GBP, as this will use their exchange rate and charge you around 7% on top for the privilege of doing so!).
