I have now received some instructions regarding the measures self-catering/serviced let providers should take.
These are about a billion pages long, and I have read them all.
The short version is this:
Contact-free key collection wherever possible. Key-safes and keys to be disinfected. No meeting and greeting unless unavoidable.
Cleaners to wear gloves, masks, aprons. Keep changing gloves and washing hands after each activity (e.g. after dealing with used towels, remove gloves, wash hands, put on new gloves).
Cleaners to keep windows open while cleaning, if possible.
Used laundry/linen to be removed from the property before cleaning.
All 'high use' items to be disinfected (taps, handles, light switches, sockets, etc) and not touched again after disinfection. Front door furniture to be disinfected; entire garden gates not!
Anti-viral cleaner to be used after hot water and ordinary detergent.
Throws and cushions to be removed completely.
Freshly laundered mattress protectors/pillow protectors for each guest.
Laundry to be done at 60 degrees.
Fogging, steaming etc are not necessary.
Guests are to strip the beds and bag up their used bed linen. Owners to provide suitable bags for this purpose.
Recommended for owners to provide single-use gloves and hand sanitiser, but not mandatory.
All check-in information, information about the property etc, to be provided online only.
In fact, this is all pretty standard stuff for anyone who owns a holiday property. I think the only major changes for me are asking guests to strip the beds, doing away with cushions and throws, and using several pairs of gloves to do the cleaning (I normally just use three pairs of heavy-duty rubber gloves - one pair for cleaning the loos, bins etc; another for less filthy jobs; and a separate pair for washing up).
So it's nowhere near as off-putting as it might seem, either for guests or for owners.
