I'd say about 300 customers is the ideal amount for 1 man, 400+ would be considered large. But it really depends on the areas worked. 400 customers on a council estate, although a large round, would not generate as much income as 200 houses in an upmarket area.Plus the wealthier customers always want all the 'add ons' each year and are happy to pay top dollar for it..
My round is 8 weekly, I have 260 residential customers and 13 commercial.I do around 8-9 houses a day, 4 days a week, with a couple of commercial jobs each week. And I thought I was overworking myself
The amount of customers doesn't matter! Its all about what your round is worth a month.In our game these days pulling a grand a week in is common practice! its simply 100x£10 houses a week or 50x£20 houses a week or if lucky 20x£50 houses a week to clean. All add up to a grand but with totally different customer amounts.
