Really happy with Henson responded quickly, a very thorough survey and a super easy App. Price competitive. Can install on weekends which was convenient for me.


These guys have been great from the outset. Arranged a site visit within days and really listened to the business needs. Tech was installed and the team were all shown how to work it. Best of all, I can still monitor the activity on my phone. Would recommend hands down.


 Excellent service would definitely recommend. Quote was sent over quickly and price was very comparable. Alarm was fitted well. We are very happy with the quality and the service we have received so far.
