What customers say
Highlights
"We had had the same alarm people for many years, but they were taken over and we were very annoyed at an outrageous fee charged for a 5 minute job last year and vowed to change. We looked around locally and thought Welwyn Garden alarms the most reasonable. We fixed an appointment some months ahead. We were fully justified. They came on time on the agreed date, and did a very thorough job. We made a great choice!"
"This was a routine maintenance visit . It was carried out on time, with no fuss by a very competent engineer who was a delight to have around."
"As usual they turned up on time did the service checked everything and sorted it for us. Didn’t try to sell us batteries that weren’t needed very honest and great service as normal. I would highly recommend them."

Welwyn Alarms do our annual service and check performance. Very nice folk, technically sound and always on time. Have used them for over 30 years!
Welwyn Alarms are always available, and always most helpful with any queries or advice. The alarm was serviced this week, and the engineer was very professional and polite. Take a bow Welwyn Alarms, you get my vote!
Welwyn Garden Alarms supplied and fitted our CCTV system and have maintained it since with the latest maintenance visit on 21 November. I like to use local contractors whenever possible and Welwyn Garden Alarms have proved to be an excellent choice. They are knowledgeable, experienced and professional with a great customer friendly focus. I am very happy to recommend them for a quality CCTV installation.
Our annual service for alarm and CCTV was undertaken professionally and efficiently with all questions answered. Many thanks
Welwyn Alarms installed my alarm and have maintained it for three years. The staff, both office staff and engineers, have always been most helpful and efficient. I would not hesitate to recommend them.
We are longstanding residential customers of WG Alarms, now across 3 different properties, over 30 years: each time we moved home, they were one of our first calls. They've never let us down in all that time and are always available to get issues resolved
We have used Welwyn Garden Alarms over many years and always received an excellent service. The whole process from booking, to visit and invoicing is efficient and professional with their engineers punctual, knowledgeable and courteous. Many thanks!
I have been using Welwyn Garden Alarms for several years now and always had a good service. The engineer always arrives at the scheduled time and is courteous. He works efficiently and completes the maintenance check of our alarm system with no fuss. It is good to use a local company
Have used this company for 20 years plus Still receiving great service and support. Have used their services for my own home plus my business premises. Good our fashion service , keep up the good work.
So easy from start to finish. The quote was fast and competitive. Communication was excellent. Fitting was fast and unobtrusive. Couldn't be more pleased and I highly recommend.
Scheduled service. Technician phoned ahead and arrived promptly and first call of the day. Courteous and competent. Everything completed and no problems. Follow-up documents arrived on the same day. Hopefully no further needs until next year!
I have been a client of Welwyn Garden Alarms for over a decade. In that time I've had sterling service and support, from friendly and courteous staff. I have recommended them to family & friends, some of whom are now happy clients.
Have been a customer for 25+ years. Service has always been very good and personal. Generally it’s the same team members and engineers. Always very helpful and never had a problem with service in all those years. Alarm and CCTV have been very reliable. Any issues (of which there have been hardly any) have always been dealt with promptly. I have always managed to get service appointments easily to fit in with my schedule. I have another property with a different large alarm co. A completely different experience all round. Not a patch on Welwyn Garden Alarms. Wish I could use them for both!
I had my alarm installed by Welwyn Garden Alarms almost 20 years ago and they have looked after it ever since - Upgraded to internet/WiFi from fixed line a few years back. Had it serviced today, technician turned up as advised, completed service and App reinstated - Very happy 😃😃😃
Welwyn Garden Alarms have been looking after our alarms for over 20 years. It is a well run, professional business. The service is always first class, and the staff - from the top down - friendly and personable. To coin a phrase - thoroughly recommended.
I used Welwyn Garden Alarms limited for the first time to service my house alarm system. I found the company very professional, and the engineer was personable. Helpful and respected my property. Would highly recommend.
We had an 18-month delay to our house refurb project, and from the first estimate, from Welwyn Garden Alarms, to installation, Peter and the team from WGA were always there to answer our questions. In the event after commissioning, there was a lingering issue with the internal wifi connection, and it was decided to install a hard wire. Job done, system working perfectly, and we always recommend WGA to anyone who asks.
