How this score is made up
Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.

Engineer Service Visit
Had our alarm fitted and maintained Welwyn Garden Alarms for a number of years now, and the recent battery service visit was quickly organised to our timescales and carried out out promptly and professionally by their engineer. Excellent Service.

Professional service
Having had a monitored home alarm for over 30 years, during that time the initial company who installed the alarm was taken over, then the taken over company was taken over, then another multinational company ended up taking over, during this time the quality of service diminished leading me to contact Welwyn Garden Alarms, I initially spoke to Peter the owner some 3 years ago and can highly recommend his company
Work completed:
Knowledgable, friendly and efficient
Having moved house into a property with an unfamiliar system, we reached out to have it serviced. The engineer was patient, knowledgable and happy to run through everything as many times as we needed in order to be comfortable, we understood every detail and sensor. A follow-up made us feel in good hands, and an accidental triggering resulted in a near immediate contact call. Superb service all round from Welwyn Garden Alarms Ltd
Work completed:
A job done well.
A very quick initial response - had to chase for a follow up but once in the “system” response times were good. Day of change over (from an existing service supplier) was completely without drama. The technician Taylor knew what he was doing, was very respectful of my home and I barley knew he was there (a good thing). Whilst not the cheapest they are competitively priced.
Work completed:
Engineer visit
The engineer arrived in the allocated timeframe, was very efficient and prompt in dealing with the annual servicing of the alarm system, was courteous and polite and left everything clean and tidy.
Work completed:
Excellent, trustworthy, friendly service.
I have a burglar alarm which is serviced annually. I have been a customer for many years. Recently, we had a new window fitted. Welwyn Garden Alarms arranged placement of a new alarm to that window the following day. It was easy to arrange. The staff are always friendly, trustworthy and professional. There is continuity with both office and engineering staff with the company which is reassuring.

House Alarm Annual Service
Having used Sentry Alarms and then Welwyn Garden Alarms for almost 20 years, I have always found the people friendly and very easy to contact, and they always arrive on time. Our alarm system only occasionally needs a new battery, and once a new scanner, and all at a very reasonable price.

Welwyn Garden Alarms the best in the business in the Herts area
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.
Work completed:
Very pleased
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.
Work completed:
Friendly and professional engineer - excellent job
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.

Good company to deal with
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 😃😃😃
Work completed:
Great service all round
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!
Work completed:
Professional, friendly & efficient.
