Chas and Dave are working at our house! No honestly - that's what they are called - I've seen Chas's business card and Dave has his name tattooed on the back of his neck! They have come to do a site clearance - dig up some concrete, take down the lean-to summerhouse and the brick shed, level the site and take out the laurel  hedge that will be in front of the house extension, (bit of a gamble as we are still waiting for the planning permission - it's in the post!)
