Smear test age in the UK - 24.5?

Hello everyone. 


I’m new here. 


I was wondering how soon in the UK can you have a smear test? 

I’m 24 (24.5 next month) and I like to be sensible about my health so would like a smear test as soon as possible. I’ve never had one done before. 

Do I have to wait until I receive my letter or can I book in with the nurse at 24 and a half without being rejected And being told I have to wait until i’m 25? How relaxed are they? 


Thank you in advance for any answers!
