Thanks to everyone for their responses.
I did think £1,200 would be expensive. They're sending me over the spec of their system so I can see exactly what it involves. Always room to negotiate when we come to choose our 'extras' later on down the line.
As they're arranging it all I'm sure...
Cheers - presumably the light getting switched on is limited to wireless?
I guess with all the wireless devices that'll be at the development, there is a fair chance they'll get some sort of interference.
Hello
Just bought a new build (not yet built) property and pretty keen to have some form of burglar alarm installed.
The developers want £1,200 to fit a hard wired one - i wouldn't be over the moon to pay it but if it's a decent system then I'll probably be willing to go along with it...
