Sounds like it may have been an aerial photo company, as this is the usual modus operandi for the speculative end of the business. That should no doubt be confirmed in short order when a sales team descend on the houses in your area trying to flog exorbitantly expensive piccies of your village. Don't pay more than a couple of quid if you really want one.
Some of them are well run professional outfits, but there are also many cowboy outfits who regularly have run ins with the CAA for breaching the low flying regs.
However, it may also have been somebody locally on a pleasure flight who just wanted to see where they lived from the air.
Either way, unless the reg was absolutely crystal clear, and as you only live in a village, I doubt they were doing anything more than being a nuisance. They can quite legally circle your village down to 500' at which point you ought to be able to read the reg without great difficulty. It's a poor reflection on the pilot's consideration for the locals though, as even for aerial photography, there really isn't the need to be as low as 500' for shooting a village.
