Has anyone come across a company installing burglar alarms but not

Ignore the 'big name' companies and try the smaller (registered) ones.
There are a couple that I've used locally (but too far from your
location) who have been happy to install/service/whatever without having
an annual contract.

They may not be too happy that you have put the runs in but as long as
they can proper installation tests afterwards they shouldn't be too much
of a problem.

I'm assuming that you *don't* want a monitored system and that it is
*not* an insurance requirement.
