Spent some more time trying to get the handles off before giving up. Then had to pick a new tap, order it and have enough time for my amateur plumbing skills.
However it is in, isn't dripping and I don't think there are any leaking joints. Had to cut a bigger hole in the panel in the cupboard under the sink but it isn't obvious unless you are kneeling on the floor.
