£200-£250 easily?
No way. Not a chance, there may be the odd and very lucky experienced pro with several years working as a window cleaner getting up to that rate, but anyone reading this thread as a newbie will be being given very inaccurate information.
As an individual, if you can average around the £100 a day mark you are doing ok.
A great many will earn more than that, and many will earn less.
BUT IT IS REASONABLE TO EXPECT TO BE ABLE TO EARN £500 PER WEEK.
If you think you are going to buy a round as a complete newbie to window cleaning and earn £200 a DAY you will be in for a sad and disillusioned awakening.
It'll take you at least 3 months before you can become even reasonably adapt at the job, several months before you really get up to speed and in the groove.
If you read these forums, the average price, for the average 3 bed semi is probably around the £6.00-£7.00 mark.
Bare in mind I am talking AVERAGE there.
You will after you have got some experience be able to do 3 houses like this in an hour, 4 per hour if they are all virtually next door to one another.
But they are rarely all so close together, they are rarely all the same type of houses, or the same size.
You will not work for 8 uninterupted hours, time is lost throught travelling, talking to customers, driving off to find somewhere to use the loo, buying a pastie and so on.
Throughout a 9 till 5 day your productive time will be between 5 and 7 hours.
If all your accounts were 3 bed semi's and you were charging £6.50 per house, managed to do 3 an hour and also managed to work 6 hours you would turn over £117 in the day.
And don't forget, you can't work till 5pm for a lot of the winter, it's too dark.
When you apply time and motion studies to your working day you will see.
But to get back to the original thrust of the post.
The physical size of a round is totally irrelevent, it isn't how many, it's how much.
As I said above, if you are doing 20 accounts a day that is 100 houses a week, 400 a month. And THAT is PHYSICALLY a large account.
But you won't have all 3 bed semi's with just 10 or 11 normal casement windows in them
Now if someone is bragging they do 600 houses every month all by themselves they must be cleaning one bedroom grannie flats
There are just too many variables to consider, and if someone has a round that are all shops, they may well have lots of accounts that only take them 2 or 3 minutes to clean, less even on some (I know, that describes much of my work) add in a big office block and one account is taking up to 5 hours to do.
