Somebody who is cleaning windows and does not pay tax and is usually also claiming benefits.
How can you tell from looking at them?
People may have made that assumption about me when I first started as itr took a while to be able to afford getting kitted out better.
I leave well alone myself.
Although they may not directly poach my customers, working illegally can hold down the rates generally. However, I would not make a snap judgement based on someone's appearance. When I started in 1991 I was skint and had an old banger Datsun Cherry hatchback, a ladder borrowed from a plumber, and just regarded window cleaning as something on which to give my old clothes their final fling. I was registered with the taxman though, had an accountant, and had public liability insurance. To look at me you might have thought I was a chancer just earning a few extra quid on the side though.
