77,
Perhaps my post was unclear - my point was exactly that, they are not non doms.
They may be considered non resident, but even if you are non resident (or considered ordinary non resident) any UK earnings are still taxable. As their place of work is UK, then that is classed as UK earnings, irrespective of how long they are out of the country for.
The non ordinary resident status only allows your foreign earnings not to be taxed by HMRC.
For example - I am non ordinary resident in Dubai, my earnings, earnt in Dubai from a Dubai company are not taxed - But I rent my house in the UK and as that is earnings in the UK it is taxed.
Therefore, as the commuters place of work is UK, its UK income and they should pay tax on it.
