I think the two things that you have noticed are correct and make good policy sense (it can happen you know). The division of contractual sub-occupiers into (sub)tenants and boarders is a slightly artificial one: they are all what most people would tend to think of as lodgers. Some get meals and some don’t, but they are the same kind of person.
Makes sense then to treat the rent income received from lodgers under matching rules: £20 disregard whatever, plus half the rest if food provided.
The mystery is why this and some other sensible tidying up refinements in the pensioner Regs are not also being applied to working age claimants too.
