Education is being strained mostly by year after year of budget cuts and constant interference by high up folk who apparently don't have much of a clue ; mental health provision is for students is, I'd guess, more of a strain nationally on the education system than immigration is. I don't have any numbers for this before a link is demanded.

The housing shortage is exacerbated by the lack of affordable housing - developers prefer to build big 4/5 bed homes as they make bigger bucks and private landlords can charge huge amounts of rent. Plus, weirdly, most folk like living where the jobs and amenities are. Got a senior town planner in the family.
