About Us

We provide a high quality security installation service across Central and Greater London, including the installation and maintenance of a wide range of leading security and access systems. Our dedicated team offers a wealth of experience and versatility, with direct access to up-to-date technical support from our suppliers.

We are a family run business founded in 1991. Starting out with physical security such as high security locks, grilles, gates and doors, we have grown to offer electronic access control and surveillance systems alongside traditional security solutions.

Bradley Mak, our Managing Director, began his career as an apprentice locksmith before founding Security Installation Services Limited in 1991. Donna Mak, our Director and Company Secretary, has been involved in the business since the beginning.
