Mike,   the trouble with gutter cleaning is you rarely ever see houses with gutters so obviously little demand

Is this sarcasm? 
 
 
. Don't all house have gutters? 
But not all of them need cleaning, I have lived in 10-5 house in my lifetime and none of them have needed to have the gutters cleaned........ every home has carpets but only 15% of home owners  have their carpets cleaned.
I would guess leaves in autumn are the big market for gutter cleaning, especially in area with lots of trees.
Unless you can get £70 for the smallest house then I can't see it being worth me doing, not being presumptuous  but if I can't make the same hourly rate I get for pressure washing or carpet cleaning there's no point putting the effort into finding the work
