Just before midnight tonight, my husband saw a van outside our house, and the people inside it shone a light at the window which had the shutters open. They left when my husband went to the window, but it very much seems like they were scoping out the house. We called 101 who took some details and told us to call 999 if we saw anything dodgy in the future. It's definitely given me the heebie-jeebies and I need the good people of Mumsnet to convince me that horrible people aren't going to break into my house tonight (or any other night for that matter!)
