Attempted break in.

I live at the end of a secluded road behind green lanes / off west green road. I was informed by my next door neighbour that shortly after I left my house yesterday evening around 6pm that he noticed a lady coming past his house towards mine, which is the last house on the road. She then signalled to a van driver parked at the top of the road who came and parked around the side of my house, which is hidden from the view of the main road. As my neighbour came out to investigate he noticed her attempting to open / tamper with the lock with what appeared to be a set of keys. But upon seeing him she quickly got back in the van and drove off. The lady and driver in question are what he described as of Eastern European appearance with curly reddish hair. Unfortunately, he was not able to get the registration number of the van.The worrying thing was that there were clearly lights on and people in my house st the time. I rang up 101 the non emergency police helpline a"to ask if anything like this was happening in the local area but was told that this type of information is not given out and simply advised to double lock the door at all times. No one in my house has lost their keys so I can't fathom with what set of keys / tools they were attempting to open my door with. Has anyone heard of anything like this happening locally? Secondly, can anyone advise me of any good security companies locally who deal with security cameras, gates, fencing etc ? It's unfortunate that I need to take these sreps but I feel there is little other options and when I have asked the council for more lighting in the parking area in front of my house I was advised that they have nothing left in this years budget to do so. Any help or advice would be welcome.
