Excellent installation. Highly recommended.

Excellent installation. Andrew visited, listened to what we wanted, gave a competitive quote then installed it with minimum fuss. No mess at all. Works very well and we are very happy with the system and the way it was done. We would certainly recommend Lenz highly.

A top quality company.

I had a security system fitted by Lenz Security about 9 months ago. We had 3 companies quote us for this domestic installation; all seemed to be good quality systems but the Lenz system impressed us the most, not least because they seemed the most realistic.

We have not been disappointed. The installation was carried out smoothly and without requiring any remedial decoration. The system works as it should. We subsequently requested some modifications to the functioning of the system and these were implemented very quickly.

We recently had a problem with the internet here following a power cut. The response to our request was immediate and full functionality restored within 2 days. It would have been the next day but we were busy!

In short this is a most impressive company providing a quality system and outstanding support. I would recommend them to anyone requiring a burglar alarm.

Top Class Service

Saved my life with an emergency visit before we were going on holiday and then returned to complete an annual maintenance and fit my new shiny bell box when we were back. Top class service both times, highly recommended!!

Simply a superb Security Company and an absolutely amazing service whereby they actually listen to what you want and put their customer first.
I'm a single Mum with 1 Daughter and I have had 3 CCTV cameras installed due to many different issues that have occurred since living here, including 8 bouts of vandalism to my properties, problem neighbors & theft just to name a few.
Since having them installed
I honestly could not be happier and much more content. The quality of the cameras and picture that have been installed are outstanding, not to mention how much safer my daughter and I feel now. 🤗
Andrew also put an app on mine and my Dad's Mobile phones so we can always have peace of mind our home is safe, at a press of a Button. 😊

Please do not hesitate in contacting Lenz Security for an extremely fast, friendly and reliable service. Don't just think about security, ACT ON IT!! Contact them today.
Thank you so much 😊
