The majority of our domestic work is 4 weekly, however I'm aware of the 50% extra you can charge for an 8 weekly clean for really not that much more work. However this does mean twice the customers if you want to fill 4 weeks of the month (roughly). Which isn't a problem, though it may take longer to fill to capacity. Now I'm considering 8 weekly. My question is, Needing double the customers would lead to potentially covering double the area than previously done so. Would the extra time spent travelling, fuel costs etc, bring the hourly rate down by much? Enough to make 4 or 8 weekly not that much better than the other?
