We had a engineer in today to do some upgrades was very consonances kept me informed on step by step of what he was doing. Clean worker and very knowable. Checked all his work to make sure everything was how it should and also repaired the outside unit on his inspection. (Phil) 5 stars from me.

Along with 3 of our neighbours we had an alarm fitted by TI about 10-11 years ago. Recently had them out to service the alarm (very polite, likeable technicians) but they said the external sounder needed a new battery. They came out again a few weeks later to say - sorry, sounder is unserviceable and needs replacing. No issue there I thought - it's 10 years old, fit a new one.

No - they say the new sounder would not be compatible with the internal detectors and the the control system. I'd have to order a new system in it's entirety. The quote was 900 odd so it's not going to break the bank but I asked if they gave any assurances that I wouldn't face the same situation in a few years when the system was outside of warranty i.e. a single part failure makes the entire system useless.

Their answer was "no" - if there is a similar fault they'd have to replace the entire system. So - if you want to install entirely new systems on a routine basis then this is the company for you. If you'd rather have a reliable system that doesn't have in built obselence then I'd advise to go elsewhere. Incidentally, their maintenance manager said the system wasn't obsolete as the external box still acted as a deterrent (I pointed out that you can get an empty box from B&Q for 20) and the internal sounder still operated (I pointed out that it's not much help if the neighbours can't hear it). As it stands my property is effected greater protection by very solid doors, a ring door camera and two very large dogs. All of these are more reliable than a TI system.

Fantastic team of engineers who are very helpful and knowledgeable. Prompt response and service. We had issues with our alarm system and needed an upgrade. It was dealt with very professionally and quick turnaround time too. Also, to mention the installation engineer Jack, who came out to carryout the work was fantastic and he did a good job. We have used the service for so many years now, especially the out of office emergency call out is spot on.

TI Security installed our alarm system at our new office premises. We were given a demonstration and instructions of how to use the alarm system which was easy to follow and all made sense. Phil had to call back out to us to tweak the set up, and he was able to do this quickly and explained everything thoroughly.

Critical: Professionalism My experience has not been good with this company, main issue is the staffs professionalism. Rude and Obnoxious.

We arranged for TI to come & repair a couple of Fire sensors & check the whole system as well as service the house alarm in my Father in Laws house. Phil arrived bang on time & spent several hours carrying out the works. He provided a thoroughly proffessional job explaining things throughout & was more than happy to explain the systems. He certainly went the extra mile & would highly recommend both company & employee Phil.

Phil came along today after we were having a problems with an alarm sensor. He explained in simple terms what he'd have to do to fix it. The service was great as he tried the cheapest alternative which then worked in the end. TI spot on as always. Service: General repairs

We had a TI installed alarm from the previous owners and it had developed a minor fault. TI sent a salesman around rather than an engineer. TI sent on a HUGE quote without lifting a screwdriver or a lid. I challenged the sales guy a couple of times. I am not an alarm fitter but I am a bit of a nerd so I could tell that he was trying to pull the wool over my eyes. especially when I challenged him and he said "we would be unable to do this as it wouldn't comply with the regulations".

What regulations? A quick call into the manufacturer confirmed I wasn't oversimplifying things. I ended up with a warrantied, modernised system for less than a fifth of the price quoted by TI. If you have a technical fault then please liaise with someone technical to price up the work. I have no problems working with sales folk. in fact this chap was very nice. However there are domain experts out there for a reason. A screwdriver, a camera phone and a quick call to the manufacturer clears this up in minutes!
