My carpet fitter managed to put a nail through a cable used by my security alarm system. I called GCD Security who attended the same day, and fixed the issue. They had to re-join the wire using a soldering iron (further repairing the attempted fix by the carpet fitter who tried to join the wire juts by twisting them, but failed to do it properly). GCD Security then used volt meters to test the connection was good. Then, the next problem to fix was to identify another reason for why the alarm didn't set. They identified 2 blown fuses and a now faulty PIR. They fixed/replaced these. Very happy with both the work, the professionalism, the fact they kept the place tidy and clean and the price to fix was very reasonable. I will certainly use them again. Thank you GCD Security.

Excellent!! Would highly recommend GCD Security. They provide a personal, caring and professional service. They surveyed my house and provided the quote quickly. They installed the alarm on the date and time they stated. On arrival they confirmed all the locations for security prior to doing the work and worked quietly and considerately all day. They were very tidy throughout. They were extremely patient explaining how the alarm system worked which was very reassuring. They also suggested some additional steps I could do to improve my security which were very helpful. I had a safe installed and this went very smoothly too. I now feel safer in my home and feel that my property is secure. Thank you.

I have used GCD at my previous house and all my family use them. I wouldn't choose anyone else. Great service, competitive prices, and their aftercare service is also speedy and reliable (unlike many other companies!). The installation by Ben was faultless, not a spec of dust left anywhere and a full briefing as to how to use the system. A 5 star vote from me!

The locksmith replaced the Yale-type top lock and bottom mortice lock on the day and at the time booked. He was friendly, helpful and competent. When adjusting the fit of the door, he identified that the door hinges needed replacing. He made the 1.5 mile trip to 'base', returned, and duly replaced the job. An excellent job was done and very good value for money.

Very prompt response/quote to our initial request. Following the on-site survey, a very clear quotation was provided. Quick and flexible arrangements for installation. The installation engineer (Matthew) arrived on time and installed the system to an excellent standard. Matthew ensured that we understood and were happy with all the installation decisions to be made. Excellent operation guidance instructions were provided.

I needed a company to replace the one I had used for 20+ years but with whom I was no longer satisfied. GCD did the survey in a professional manner, decommissioned the existing system and installed the new one. The engineer, Ben, was personable and thorough and gave us a good briefing on the use of the new system. As it has only been in a day we have yet to use it 'in anger' but have no doubt that GCD will be responsive if we have any issues.

Having recently been ripped off when I had a problem with my back door by a company I found on the internet, I decided to use a local firm when I had a problem with the front door. Knowing of GCD in the town I rang up first thing Monday morning. They arranged a call that morning and Ben sorted out the problem within 30 minutes The charge was £78 compared to £310 on the previous occasion. Very professional and tidy. Would certainly recommend this local company.

I have recently had a full alarm installation and I cannot recommend GCD Security enough. The installer was very polite, professional, tidy and helpful in explaining how the system works when he had finished the job. The costs involved were very reasonable considering the kit involved and a full days of work. A very happy customer!!

Which? Trusted Traders nails it yet again! I highly recommend GCD Security. Not having had either cctv or burglar alarm before I got a couple of quotes before making a decision. It became clear quite quickly that Paul from GCD really knew his stuff and also appeared to be a genuinely nice guy, having taken the time to fully answer all my questions. The installers, Bob and Ben, were here for a day and a half and we’re fantastic. Diligently wearing their face masks and putting on protective covers on their shoes every time they entered the house from outside. At the end, they explained thoroughly how the systems worked, and since then there have been a couple of very minor technical issues which Bob came back and sorted quickly. Very impressed and would not hesitate to recommend GCD.

Very pleased with the alarm installed by Paul’s GCD Security firm. The engineers were extremely professional and courteous and performed the work to a very high standard. The team arrived on time and stayed until my wife and I had been thoroughly briefed with how to use our alarm and app. They also tidied up after installing which was really appreciated. I would highly recommend GCD to anyone considering an alarm and several wireless PIR sensors. Many thanks!

Very happy with GCD - I found them to be trustworthy, responsible, professional, and excellent throughout. They supplied and installed: alarm, locks, cameras, PIR light. I chose their quote because it was so clear and covered all my needs and requests. They took the time to make absolutely certain that I am completely comfortable and confident with every aspect of my new security set up. And indeed I am. Extraordinarily diligent and conscientious. Highly recommended with many thanks.

We used GCD to install locks in our rented property - they were also tasked by our managing agent to service the alarm. a) Security bolts were installed with a screw that only protruded a few mm into the door. The bolts would have failed immediately during any break in attempt had we not noticed; b) Part of a door was broken by an engineer allowing it to blow freely on a windy day. The engineer can be seen looking at the damage done on our CCTV, however when questioning them about it they feigned ignorance; c) When replacing the locks, and without our permission, they threw an entire keychain in the bin, including keys that fitted other locks in the property; d) They failed to notice that the outside siren had failed entirely during an alarm service; f) Invoiced an incorrect total; g) There were issues with alarm sensors. GCD had the audacity to suggest their inability to fix them could have been our own doing as they saw the Installer menu had been accessed. This is despite the audit log clearly showing the menu was accessed after we reported issues on each and every occasion. GCD were offered to attend to verify this, but declined; h) They changed the alarm installer code from it's original setting, without our, the managing agents, or the landlords permission, and are currently refusing to supply it without us agreeing to sacrifice any warranty on their work. Their MD did attempt, and mostly resolve, issues (a) through (f). The remainder are still outstanding.

The trader replied (on 04/12/2020)
Thank you for leaving your review, we take all feedback seriously and as you pointed out I personally have worked to resolve all the points raised. With regard to your last points and in respect to the alarm system which was not installed by GCD but by another company some 10 years ago, we were asked to resolve some issues with this alarm by your landlord and via the managing agent. The issues in question were intermittent faults, which our engineer believed to have resolved. However after a couple of days the fault seemed to have returned and after a few further site visits the issue had not been resolved. I then attended with the engineer and instructed him to replace a sensor and change the engineers access code as this had been used, according to the alarm log, when GCD Security had not been present. On carrying out these works, we than had no further issues with the Alarm system. The engineers code is designed for the installers use only and not the tenant as it has access to programming functions and could prevent the alarm from operating correctly if used by untrained persons. Changing of the engineers code was not an issue but we were not prepared to give you, end user the code, we were prepared to make alternative arrangements which were offered to the managing agent including three options to resolve the issue, but two of these options would have sacrificed the warranty on any works carried out on the alarm. At the request of the managing agents. Regards PH

I could have obtained cheaper work but I'm convinced that I couldn't have bettered the quality of the work by GCD. I received excellent care and attention. The staff on-site were pleasant, helpful, and clearly very competent. The work was completed on time to the agreed price. They are not a here today, gone tomorrow organisation, so I am confident I will receive any ongoing support I need.

I requested 4 locks to be changed as we have moved in to a new house. They had someone round to measure up on the same day as original enquiry and the works carried out the following week. They talked me through all the options and if there was a choice that we hadn't discussed (ie. Multiple.locks on 1 key) they rang me very quickly to get an answer to.make sure the job was done exactly as we wished. Very professional, well priced and knowledgeable.

GCD Security are a local business to us and we were looking for home security work to be completed on the house. From the initial contact in the shop to the person who completed the work, they were pleasant and professional. We are now looking for additional work to be completed by GCD Security. More than happy to recommend them.
