Installations, maintenance and repairs
Security installation, maintenance and repair specialists across Central and Greater London.
We are a family run business founded in 1991, providing a high quality security installation service across Central and Greater London.
At first, physical security in the form of high security locks, grilles, gates and doors was at the forefront of the business, but as times have changed, electronic security has become more widely available and the Company embraced this to offer electronic access control and surveillance systems alongside more traditional security solutions.
With over 30 years experience, we provide fast and efficient installation, maintenance and repairs of a wide range of leading security and access systems.
We have used SIS for many years and gladly recommend them. They have always been prompt, professional, courteous and knowledgeable whether it is simply changing a small lock, or installing a complete security system with CCTV, security doors and entry systems.
SIS have consistently been very helpful with any queries or works we have requested. They have a dedicated and reliable team with excellent customer service and technical support. The detailed communication and constant updates are always greatly appreciated!
Security Installation Services Limited has been a great asset in our team to provide a good service to clients and go out of their way to assist in any emergencies that occur. I would highly recommend using them for the professional service they provide.
An all-round excellent service. An engineer arrived on site almost immediately and went out of his way to make sure the job was completed to the highest standard.
Punctual, reliable, sensibly priced and above all friendly service accompanied by good advice for all security situations.
Security Installation Services Limited are quick to deal with an emergency, I manage many multi-occupied buildings and SIS take full responsibility for distributing keys to the occupiers on site and provide a quick and easy service for supplying additional keys.
