Hi there,
I was in a really similar position. I lived in halls in first year for the experience, then commuted in the years after.
Flatmates are a bit of a lottery – I became close with some and barely saw others, so I wouldn’t worry too much about missing out socially if you commute. The main thing halls gave me was independence, like budgeting and experimenting with cooking.
You can still make friends in loads of other ways though. Coursemates are a big one – go to induction, try setting up a group chat, and suggest grabbing food after lectures so you’ve got people to go to Freshers’ events with. You can join societies and sports clubs too, and most let you try taster sessions before committing. I also made friends through part-time work, volunteering, and things outside uni like open mic events and pub quizzes.
Plans can be a bit more spontaneous in halls, but it really depends on your flat. You can still have a great social life as a commuter, and some unis even offer short-stay accommodation (1–2 nights) if you want to stay over for late events or exams.
Hope that helps and good luck with starting uni 🙂
