    Customer in London

  • I was very pleased with the speed and promptness of the attendance and the work carried out. I was given all the information that I requested and a full explanation of the work carried out. The guy was extremely helpful, personable and worked efficiently to resolve the problem. I would use them again with no hesitation. Customer in Enfield

  • From the initial contact about the services provided right through to the completion of work a month or so later, Lewis was 1st class! Friendly, punctual, extremely thorough and professional. The quality of work carried out was exceptional and nothing was too much trouble. Wouldn't hesitate to recommend Lewis to anyone who asked. The fact I will be getting him to do a few more bits in the future is testament enough. 1st class service! Customer in Bishops Stortford

  • LJS Security was recommended to me. LJS's work was of the highest standard, reliable, tidy and trustworthy. The products LJS used are quality, viewing and monitoring my house from my tablet are crystal clear pictures. I would not hesitate recommending LJS Systems. They are a very reliable and honest company. Customer in Watford

  • “LJS Systems were excellent from start to finish. They were helpful when assessing the job, provided a competitive and fair price, were not pushy (like some bigger alarm companies) and always available. All the staff were polite, knowledgeable and genuinely nice to deal with. We had a couple of minor issues (part was missing and another had a fault) but they guys went out of the way to sort them out (coming out on a Sunday to finish install). Really pleased with the outcome and would not hesitate in recommending them.”
