Hey, I asked what date is available on my first consultation as I wanted them before my holiday and needed 6 weeks in between the op and when I fly and they only had 4th May and about 4 spaces left for that day.
A few days before even seeing my surgeon I asked how many spaces were left as it had been nearly a week and a bit and there were only a few so I put down a £1000 deposit to pre book this and was so happy I did as I loved my surgeon anyway.
If you definitely know you want this done and are happy with everything and confident enough, I would try secure it with a deposit as there are limited spaces and can go
Hope this helps xxx
