Hi Mcbab
Good morning, I know you haven't asked but I would be inclined to downsize to a 3 or even 2 bedroom house. Just for yourself and your DH, do you need so much space?
Anyway, to answer your question, I think you would need at least 3 hours per week after the initial "deep clean" has been done. My DIL and DS have 2 cleaners for 1and half hours weekly, so working together makes up 3 hrs, they pay £40 per session and do a good job, they have 2 small children so need some help.
Good luck in finding someone suitable, preferably recommended by a friend or acquaintance.
One bedroom is an office for my OH another one is where I paint and sew. My children live abroad and I need the space for when they visit with their children. This is why I cannot downsize
