El Saxo: PM sent; no rush, just grateful for any advice you can give.
Loz: you may well have a point there! I wish you'd suggested that before I bought my new house tho!

. I can't imagine it will take long before we do forget the code and end up not using it... Anyway, it's probably a seasonal thing - pikeys coming down south for their summer hols...
Stuuk1: I actually did speak to the previous owner yesterday when the tv/phone guy set it off and I got a code from her but tho she's lovely, she also seems very stressed so I'm trying to let her get settled in her new house before inundating her with questions!
