This really is so important to do.
Please, do not insist that your DS go to a particular university based solely on accommodation costs.
I totally understand you saying that universities in places like London or Bristol are beyond what you can afford. But there again, maybe they aren't that much more expensive.

"First year was about £6600 for 42 week contract in en suite self catered room in halls. That's now £7400 with recent inflation."
Halls at UCL in London start from about £225 per week catered on a 39 week basis (12 meals per week - although back in my day it was 16 meals per week). So an extra £50 per week to include meals compared to Leeds self catering.
Although, to be fair, the top end of halls do cost in the region of £385 per week catered or £312 per week self catering.
But seriously, do please let your DS consider first what is the best course and/or university for him and only then think about what might be affordable.
For example, Warwick Business School has an excellent reputation (it is ranked 2nd in the UK by the Financial Times) and does a number of different undergraduate degrees and there are related degrees from the University of Warwick that are also highly rated.
Warwick is also really cheap when it comes to accommodation. It starts from about £120 per week self catered with a shared bathroom to around £200 per week self catered with en suite.
But again, do not even think about DS choosing Warwick based just on the cost of accommodation.
