I've had it done in the UK (was actually from a referral from Ireland, I moved in between getting a dodgy smear test which was repeated by the NHS) and I can honestly say I didn't feel a thing.
I went to a colposcopy unit, I honestly don't believe there's the equivalent in Ireland where it is quite literally all they do and they're qualified to that level. (I know there will be similar but my memory is they will do a mix of gynae procedures rather than just colposcopy) I have always found smears painful, and I didn't feel anything, including the biopsy. There were incredible competent women, I was back twice before being discharged and I felt so well taken care of.
I don't remember the specifics but I think they would have offered sedation depending on what they found- I needed a v small area biopsied, I can see it could have been painful if I'd needed multiple areas. I have a feeling if I'd wanted sedation it may have involved a separate appointment, but they reassured me it would be no more than a pinch and I didn't want to waste another day and it really was painless. So- ask.
But honestly, I've spent my adult life divided between Ireland and the UK, and like almost all Irish people I know, I rhapsodise about the NHS. It's an objectively higher standard of care in most ways, so I'm not sure why you'd call it barbaric. Whatever technique they use, in my experience, does not cause pain. It may be in Ireland the practise is to take a larger sample, or use a different instrument. But given you haven't experienced the procedure it's a bit random to claim it's barbaric without pain relief when thousands of women have no complaint.
