Thats a good point actually, with the big hols so close you might get more of a "I will do them myself in the holidays" mentality creeping in. Along with the annual influx of summer cleaners and the cost of actual holidays, interest rate rises it is not that surprising.
For some unknown reason though, I tend to get calls come along in a bunch then I get nothing for a while. Though I am newer than you so I probably experience it more.
