GCSS Limited Reviews

Really Professional & Efficient service from Jenny and the team at GCSS. We purchased electric automation for our gates and nothing was too much trouble and they really went the extra mile for us. The gates are fabulous and the cost of automation was very competitive. I shopped around and I can honestly say their the best in what they do! Lovely kind family run business.

Just got alarm installed to our new home by the GCSS team, excellent and professional service from my first phone call to them. Definitely recommend them

I had an absolutely fantastic experience with GCSS. From the very beginning, their communication was highly proactive — always keeping me informed and making sure every detail was clear and transparent. They quoted top-quality products, and the results speak for themselves: a beautifully installed solar system using premium components like Longi panels and SigEnergy batteries. The installation was incredibly neat, with all components tucked away cleanly and thoughtfully, keeping the setup as discreet as possible. Everything was up and running exactly within the promised timeline — a rare thing these days! Special thanks to Jenny, Gary, and Michal for their professionalism and care throughout the process. GCSS exceeded expectations in every way, and I’ll 100% be working with them again in the future. Highly recommended!

Gary and Michal from GCSS limited installed my alarm and cctv recently. The lads were both great during the installation. They explained everything very well beforehand and gave us a great demo of how to use the systems and set up the apps for us afterwards. The cameras and alarm give us great peace of mind. Being able to check the cameras from my phone is fantastic. Both apps work very well and are very straightforward to use. Jenny in the office was so friendly and a pleasure to deal with. No problem recommending GCSS. Great people to deal with.

Gary & Jenny are very efficient, helpful, and super professional. I would highly recommend them to anyone for both their cameras and alarm systems. The camera quality is next level. Special thanks Gary for your help getting us up and running in the new house, we appreciate you for making it stress-free for us. Caitríona & Diarmuid.

We had an old alarm system that was installed when our house was built. We approached GCSS with a view yo upgrade the alarm system which was 20 years old. and also now included new windows and doors. Gary and his team came out did an assessment of our current system., identified what could be kept and what was in need of upgrade. While we were getting the alarm upgraded we also had some cctv installed. Gary and his team were extremely neat and tidy in their work and explained how everything worked and how to sent the alarm in various modes and settings. Any time I've had a question or query Gary was fast to respond and quickly dealt with my queries. I highly recommend GCSS and have recommended them to friends who have gone on to also obtain services from GCSS.

I recently had solar panels installed by GCSS, and I couldn't be happier with the experience! From start to finish, the team was incredibly professional and knowledgeable. They walked me through the entire process, answering all my questions along the way. The installation was smooth and efficient, and the crew was respectful of my property, ensuring everything was left tidy. I highly recommend GCSS to anyone considering solar energy. Their excellent service and quality work truly set them apart!

Had GCSS fit alarm system to our new house. Very easy company to deal with. Everything organised quickly over the phone with Jenny and the lads that called out to do a quote and then later fit the system were friendly and professional and got the system fitted in no time. System is working perfectly.

GCSS are excellent. We just moved into our new home. We could not get our insurance till alarm was in. Gary and his crew put the alarm system in the next day. Gerry & Clare Cosgrave

Gary has installed 2 systems for me over the last 8 years & provides an excellent service. Top class & Neat installations ,never leaves until i am completely satisified & provides a backup service on rare occaisions when i need it. Totally Recommend

Gary provided a very competitive quote for a full security system in our home. He was extremely polite and friendly. On the days of installation, himself and his team were very professional and thorough with their work. They did a really tidy job and we are delighted with the security system. We would highly recommend GCSS.

GCSS has been our choice of security consultants since our inception. We have worked with Gary and his team for nearly 10 years now, their knowledge, professionalism and quality of back up service it second to none. We operate warehousing where we need high quality security systems for the security and surveillance of our customers goods , Mr Collins and his company have always provided us with the best options for our needs. We have and will continue to recommend GCSS to all our colleagues and customers.

Gary and the team at GCSS are responsive, resourceful and incredibly professional. We have great peace of mind our home and family are safe and secure with our monitored alarm system!

Had our house alarm fitted by Gary and Michael. Both professional and a pleasure to deal with. Every query was answered and explained, even outside of office hours. The workmanship was second to none, and I would have no problem recommending GCSS to anyone requiring any type of home security system.

Highly recommend GCSS. Extremely professional. The installation of my alarm system was seamless. The on going support is fantastic. I have no hesitation in recommending Gary & his team.

I recently engaged GCSS on a commercial project for Gate automation, CCTV and alarm. I could not be happier with the level of professionalism shown throughout from the first call I knew it was the right choice. I would be happy to recommend to any looking for similar. There are a lot of chancers out there so trust me Gary is worth the call to set your mind at ease. All the best on your next projects no doubt you'll be in demand.

I've had the pleasure of dealing with Gary and GCSS several times throughout the year's..I could not be happier with the installation of our house alarm. He was extremely friendly and not pushing the sale but more interested in what we genuinely required and conscious of our budget. We had another large alarm company cold call to our door and everything seemed to be an added extra.I have found it very easy to arrange for any servicing issues that arose and he always returned our calls very quickly. Thanks again Gary.

Very accommodating, arrived straight away and solved problem with my electric gates, i also had GCSS out in past to upgrade alarm system, professional, quick, clean and tidy. GCSS is the first company I ring and after that call there is never a need to call anybody else. Very friendly and reasonable.

GCSS Ltd fitted and maintain my home alarm system. Gary and his team did a first class job. I can't recommend GCSS highly enough for the quality and professional service they provide. Kevin Keating

I’ve used GCSS for over ten years and i would not hesitate to recommend them. I have security, cameras and an electric gate. All services work so well. However the best part of GCSS is Gary and how responsive he is! He will go above and beyond for every customer!
