I wouldn't assume that just 'cos you're a window cleaner that people think you're a burglar in disguise.
We've had a spate of burglaries in Chepstow, and one of them; honest; happened to a customer of mine around an hour after we'd cleaned their windows; just last month.
The burglar(s) gained entrance through an open light in a conservatory, and when my customer said the window cleaners had just been round before, the police thought this a good thing; since it would be easier to find finger print evidence.
Non was found though; it was thought he/they were wearing gloves (we'd obviously cleaned them well

).
anyway all sorted. he was ok. going to let the community officer know we are in the area.
I've just re-read your post; don't let the community police officer know anything; what a complete waste of time they are. Ask them if they've been issued with their swimming arm-bands (just in case a child is drowning and they stand by and watch) or their 'hiding in a cupboard badge' when something nasty looks like it's going to happen.
Blunkett's Bobbies get picked on by small children; they're only good for checking tax discs.
No proper copper with any common-sense would've wasted tax-payers money, to waste your time.
