Luzdoh no, not rude at all. It came to £5,600. Free consultation beforehand. I took it out of my investments and it was the best money I've ever spent. It was at our local Spire hospital - look up www.spirehealthcare.com/locations/
In some areas this is done on the NHS but not commonly nowadays. I don't know whether our local NHS would do it, I didn't even bother to ask, because I didn't want to be humiliated. We had our cataracts done on the NHS about 10 years ago but I don't think we'd get them done now under present cash-strapped NHS conditions. I had to argue even for that - I was doing GCSE Maths at the local community college and I couldn't see the board. I was asked 'And do you really need to do your GCSE Maths?' I responded 'Yes I do!'
By the way Spire do a 0% loan but that may depend on your age. It is really well worth it for the comfort, the absence of backache, the disappearance of yeast infections needing Canesten, a whole lot of things.
