Testimonials

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.

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.

We are indeed a happy customer. Speed of response is always good which is important to us. In general, a good service.

Punctual, reliable, sensibly priced and above all friendly service accompanied by good advice for all security situations.

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.
