Hi Darren,
I started the windows as i have bin customers asking me about it so looks like a few want both.
The problem with cleaning bins is the waste that you can produce and how you dispose of it. I have a large iveco daily which is kitted out with a wash bay in the back which includes a 500ltr waste water tank and a catch tray to collect any crap you wash out of the bins. You need to be licensed with your local water authority who will give you a chosen location to dispose of your foul water down a foul water drain, now this might be at your home but it might be elsewhere. The EA would not be pleased if they discover you dumping down a storm water drain. You can kit yourself out with a cheap 2.8kw genny and a standard karcher pressure washer for the actual cleaning to save pennies but you would still have the problem of where you actually clean the bins. I do know lads who wash them on the side of the road and just let the water waste run down the gutter but i think it really depends what your local enviorment enforcement officer is like as to getting away with this. I charge between £3/ £3.50 for regular customers and about £6 for one offs. Once you have the bins clean after the first wash it really is a quick maintance clean after that which i can do in about a minute. As an example this coming Monday i have 110 bins to clean in a very compact area which i can do in about 5hrs so yes you can earn a decent amount doing it but it does take time to build up a round such as that. The other thing you need to realise is that you can only really do them on the day they are emptied by the bin wagons so that could be a problem for you if the custy is out of your way on that particular day. Me adding windows to my bin cleaning is easy as obviously i can do the windows any time but adding bins to a window cleaning round to me would be far more difficult. Anyway any questions feel free to ask.
