After much research decided on "3rd eye security" as being the company of choice. this was due to them meeting the necessary standards in the security industry. Also, they area "which trusted trader" This should speak volumes.

Customer Service
We have used 3rd Eye for 30 years and have been very satisfied with them. If being fussy, they could do with a lesson in using a dustpan & brush!!
