I notice Kupo mentions Boots as a source of nappies above. I live in Ireland and currently use Boots as the source of my nappies. I tried a pull up/underwear type a few months back and didn't find them useful at all. I may have bought a size too big.
The Staydry Slip 10 medium/large pack Kupo mentions are the ones I currently buy and are in my opinion very comfortable, and highly absorb my pee. I haven't had a single leak (I've used two packets over the course of the last maybe two months). They do stick out over the beltline though, so I don't wear them outside or blatantly in front of family. They do also hide the smell of my pee very well. I haven't tried pooping in them yet though (I'm fairly new to diaper loving regularly wearing them, and have yet to poop in one), so I don't know if that will result in issues. I live with others, so that would have to be while they're out, and I've enough time to clean myself up and destroy evidence before they get back.
I'm happier in them too, because as Kupo mentions above, they're sealed with four tapes at the front, so they've a more baby like feel to them, unlike pull ups. Nappies to me as I remember from being in them and seeing my brother in them were always like that with the two tapes at the front (I was a pampers baby!), so I'm happier wearing ones like that.
All I would say though is the price in Ireland anyway is €12.99 a pack, (Kupo mentions £9 above) which strikes me as quite expensive for a ten pack. Would anyone know a source of cheaper over the counter/shop purchases for adult nappies in Ireland?
They are shown as for heavy bowel and bladder weakness. Having said that, having had no leaks, I try not to pee too much in them. I don't know if they would hold being peed in two or three times.
