You can choose your hours, and it 8s easy to move clients for appointments.
I manage my own clients according to my schedule. I can have as many clients as possible, usually 2 to 4 clients in a day.
Self employed, schedule your cleaning work in, arrive at clients house, compleat the clean. Then commute to the next client, complete the clean. Repeating untill then cleans for the day are finished. Work is scheduled in for as many hours as wanted in a week. Your tax an NIC is your responsibility to pay. Payment is made at the end of each clean.
No pay for absence or holiday.
