Sadly, the UK is rather disorganised and your daughter's friend will have to go through a separate verification process at practically every point of contact in the UK, some of which will not be able to cope at all and likely send her in circles. This stems from there being no central record which any/all individuals can place themselves on which then is taken seriously by all authorities/institutions/entities in the country (as is the case elsewhere). As a result everyone your daughter's friend approaches will dream up their own criteria and approach all contact with the main thought of covering their own behind. A few years ago my son arrived in Denmark and in the space of just over an hour (including waiting time) was registered for everything, had a GP and a bank account - I mean everything, down to an ID card on the way which was everything including a metro/bus discount card.
