When I do the math it comes to about 8.27 per hour for the 309.25 per month. I have found in the past that I can clean some places in about 3/4 of the time to a better standard than other companies I have replaced. The problem is when I bring staff in. If you do not have the staff that can perform to your standards it is harder to charge a premium. If you are planning on doing it yourself, you will probably be surprised. I have been able to bid jobs at a higher rate, convincing the client that quality will improve. I spent the time getting the place to standard, then I find I can keep it to standard in a lot less time, never had any complaints yet. I have some clients that I use staff with and some that I do myself, but I have cleaned everyone from the begginning so that I can show my staff exactly what needs to be done to keep the client happy, and believe me that varies greatly. I have one office, as long as the pots are cleaned meticuously then they are happy. They could care less about the rest, but dont slip up on those pots, not one little stain in a tea cup. That one is 5 hours a week, it takes me around 2 1/2 hours a week now that I have it to standard and I still get the original amount that I bid and I bid it at about 10.50 per hour. So basically I am making about 20 per hour on it. I had a girl in there for a bit, but she almost lost the client for me so I had to sack her, I will get someone else in later but until then, 2 1/2 hours per week is not bad and it is only around the corner from my house.
TUPE can be a problem, but to my experience, it is only a problem once it becomes a problem. Warn the client about it, it really should only come into play if the current cleaner has been there for more than a year but always check it out, it does not matter how long the cleaner has been with the current cleaning company but how long they have worked on the clients site. If it is the cleaners fault and you go in there and make them do thier job, they usually will not stick around long.
Cheers and good luck
