Premier Inns laundry service is contracted out to clean laundry services also do Hyatt and an awful lot of London Hotels.

What benefits would a company with a good reputation, and an ever increasing number of (land-based) hotels, gain from becoming a sub contractor for an overnight sleeper train?
Again, I said
Whitbread. I wouldn't suggest painting the train purple; the point is that it's the back-end systems, contracts, resource and contingency that could possibly be applied to The Caledonian Sleeper and it would still be green.
Surely it would have to be a Travellinglodge?
Joking apart though, everything about these hotels is subcontracted, so the question doesn't really apply. If stuff is subcontracted out it may well already be to the same kind of people!

In the 'heyday' of sleepers, it might be worth remembering that a good part of the operation was intrinsically linked with the railway's hotels. Indeed, this continued with British Transport Hotels. Passengers generally, for example, took breakfast at the arrival station's hotel (if they wanted a proper one) - and this was at a time that sleepers were a sizeable operation. They're now not, so the intrinsic inefficiency is almost unavoidable.
If that risks destabilising the entire service, then folding the railway operations back into a train operating company to leverage their efficiency, contingency and redundancy (even a freight operating company in today's set-up), and the hotel operations into a suitable hotel operating company, again with their specialisms, efficiencies etc.,
might be better than the current situation.
And given that this is a Premier Inn associate brand restaurant, I don't think that there's any reason to be the least bit sniffy about whether a company like Whitbread knows how to pitch service levels appropriately:
