Spiders VS living in London

hi, i'm a guest on this subreddit and i am looking forward to moving to england in the very near future, whether that be with my family or into a dormitory for one of the many colleges there that i am interested in. the only thing that is making me reconsider is that i've heard the abundance and size of the spiders in london, especially during spider season, is absolutely absurd which doesn't help because i am very arachnophobic!!

for reference i currently live in socal so the spiders, as far as i'm aware, range from small to medium in size but absolutely mortifying personally (this may also be influenced by my mother's elaborate garden connected to our house)

with this in mind, what would be a good housing option for me or maybe my family if they come along? would higher-story flats be better than lower in terms of spider encounters, or vise versa? thank you for your response :)
