Welcome Alyssa, & happy new year.
Story: UK has been harder hit than some of parts by cost of living crisis. And even in the best of times, the supply v demand equation is more favourable to the punter than in much of north America. So may not be the easiest place to earn money. That said, we'd love to have you here!
Tradition WG's have a tradition here called the tour. It's when WGs stay in one town for a week or so, then move to another, sometimes traveling quite a distance between stops. This might suit you as a good way to see different parts of the UK. Maybe start up north as costs are lower and it may be a good way to get feedback. (You're main platform is likely going to be Adultwork, and it gets easier once you have some reviews on there. On this note, consider setting your intial rates quite low, maybe even just 80/hour for up north - this is advise you probably wont get on WG forums! It's easy to raise them later.) Best way for you to travel about UK is probably by train. In the bigger stations there may be taxis waiting to take you to your hotel, or there is Uber, or you can go old school and find the number of a local taxi firm. You could post on a WG forum to ask for a good punting hotel to book for a specific are - but generally I think you'd be fine if you book from one of the bigger chains.
Legal & Rules While its good to follow the law to the letter, we're not that rule bound in UK compared to many places. If you're sensible and try to be considerate to others you'd probably be fine. In particular, while brothels are illegal, they are openly tolerated in some parts. If you're not adverse to brothel work, you could do worse than look up Milton Keynes Escorts as a place to start. (You could / should also register on Adultwork and seek some work on there for the days you're not on the MKE rota.) I consider Milton Keynes & MKE as a nice safe place to live and work. You could benefit from great advise from the experienced Maids and some of the friendly older lasses. Could be a good place to build relationships.
As a caveat - you might not get such a great experience. I've not been there much since 2019. It may be that in 2023 the maids are no longer friendly. Sometimes they might send you to work in a flat with maybe only one other girl and no maid physically present. And while the girls generally seemed friendly to each other, there were reports of bitchyness in some cases. That said, many lasses have found it a good place to start, after a few weeks or months they move on to become fully independent or work for more up market agencies. Regarding agencies, I think a rule is you're not supposed to give punters your personal number. That is a rule that is often broken if you find a punter you really click with (though maybe better to wait for the 2nd visit.).
It's not a legal requirement, but a good rule to follow is to get medical checks every month or so. The WGs forums can advise on how to get that done at no cost. To be blunt, having OWO on your list of services is likely to boost your income quite a bit, though it does come at a small risk.
PS - while many are suggesting you start in Northern England especially if you're going on an independent tour, I hope you come and visit us in London before you leave! Finally, would be interesting to see your answer to the 'What makes a girl choose escorting?' thread.
