Hi gem0307, I booked in for 28th December last month, I paid a £500 deposit to secure the date. I’m not sure how far in advance you can book though as my PC only just had the surgeons schedule for December/ January when I booked.
I would ask your PC how far in advance you can book, if you can’t book for when you want yet ask her to let you know as soon as she gets available dates for the month you want through, then you can book straight away. If you carry on saving from now getting the date you want shouldn’t be a problem as you will have the deposit you need to secure it
good luck hun! x
