Undo the swan neck by undoing the round nut and lift it clear, or there could be an allen screw around the back. You'll see one or two O rings that need replacing on the stem.
You may need to bulk the O rings out by wrapping some ptfe tape in the grooves first!

You need to change the rubber o ring seals at the bottom of the spout. There usually a screw athe back ( prob nedd small allen key) - when screw removed, you can lift the spout out. You need to identify the make and model and get the correct o ring kit.

OK, that was easy enough. It needed a flat screwdriver rather than an allen key, and I spent most time looking for a screwdriver short enough to fit between the tap and the wall...
Now to get replacement seals.... there is no name anywhere that I can see, so I guess I’ll try to measure the slot and buy by size.
Thanks, Phil.
The slot is about 2.8mm wide; the diameter at the bottom is 14.5mm, and at the top is 18.0mm.
The remains of the old o ring is about 2.7mm diameter.
O rings seem to come in every possible size. Does anyone know what “common” sizes are for these seals?
Otherwise I will probably order 14 x 3 mm and see if it fits.

I'd take the thing to the shop to make sure. And smear the new O-ring with silicone grease.
Here are the new 14 x 3mm O-rings fitted. They are a good fit to the depth and width of the slots.
It does not push easily back into the body of the tap. It’s not easy to push because of the position - am I going to have to remove the tap from the sink?
I think when I have got it a mm in, the O-ring has been forced out and rides up. Are the O-rings too big?
Thanks!
I would guess they probably are. And did you grease them?
Looking at the channel in the pic, you need flat O rings not round ones.If its a branded tap the manufacturer may help
Your new rings do look a tad too big. There's no groove space left for them to squeeze down into. Do you have any skinnier ones of the same major diameter, or ones of the same thickness but smaller major diameter? You can probably get away with round-section rings, even if the originals were flat.
Yes I did, though after I took the picture above.
Looking at the remains of the old o-ring, it is still more than 2.5mm diameter despite the wear so I would be surprised if 2.5mm is right.
I was not aware of “flat profile” o-rings. Can anyone offer a link?
I'd try slightly undersized O rings and then stretch them over, they should then sit flatter into the groves. Looking at the pic of the broken one it looks like the originals were round to start with and over time and use they will have flattened.
That being said, how old is the tap, does it owe you anything? You may find a name/number at rear bottom of the tap, check with a mirror.

Did that do the biz?
