“Simply brilliant. Patrick changed a lock at my rental flat. It was a job and a half because of the door and all sorts BUT the job he did was excellent. New lock fits better than old one and is a solid beauty. I am very pleased with the work done , the skill shown , the neatness and tidiness of the work - I have no hesitation in recommending this company and will be sharing their deets with friends. Excellent value for money when you look at the quality of the lock and the time and patience they spent getting everything perfect.”

Highlights
“From beginning to end of the job, Associated Security were professional, helpful, clear and tailored the alarm to our needs. The system is now installed and is such a huge step forward in house security and ease of setting that we are all thrilled. Thank you so much.”
“ASG did a phenomenal job of installing my CCTV and doorbell camera and I recommend them 100%. For exactly the same spec and work their quote was substantially cheaper than Banhams. Both companies are governed by the same industry bodies and certifications etc. Michael who did the quote was helpful and efficient, and Mark their installer was punctual, pleasant and did a good job. If I were in the market for an alarm I'd trust them to do a great job of that also. They're a family-run business and it felt that way in every interaction I had with them. What a refreshing bunch they are!”
