From experience (a long time ago now, thankfully) of having our place done over three times in six months. The best thing you can do is security mark your property with one of those magic UV pens.
Police never even bothered to investigate our burglaries (I know this as I asked our neighbours after our second and third one and they'd never been contacted by the police - the 'street' only had two houses on it, so not hard to go round and ask if they'd seen anything).
However, we *did* - *eventually* get our stuff back as on a raid of a Fence's house, about 3 years later, there it all was, with my name and postcode on it...
