I think it does better down south.
There was also some negative news in the media about checkatrade not to long ago, not sure what though.
Personally I feel there are better ways to bring work in, you find with sites like that it's customers who want cheap work doing, price first quality second.
Also I feel you lose the personal touch with customers, your there because a 3rd party website put you there, any problems and your going to have such websites involved.
It was watchdog they were on, it's just come to me, for not allowing negative reviews to be left for cowboy tradesmen.
