There seems to be a lot of tin pot firms out there, even with the SIA. I work for a large company as a Patrol & Response officer. In my personal opinion, you need to go with a large company. Our prices vary from Â£300 - Â£500 per year for keyholding with no call out charge to just call out charges of between Â£30 - Â£50 per hour.
some smaller firms do have a dedicated service,aswell.
charges vary mostly who the client is and how far away and how big the premises,we charge 15Â£ for a lockup/opening.20Â£ for an alarm response,in the first hour thereafter 15Â£ for every other hour.contract fees about 150Â£ varies depending how many keyholding sites the client has with us.
