We have been using this company for approx 8/9 years now for Emergency call out, Alarm and CCTV installation and service on 2 different properties. The guys are always polite,friendly,courteous and tidy. They spend time to explain everything to you and very competent at what they do. We have just upgraded our CCTV to full HD HIC-Vision giving a much better quality and improved night time vision. Have no hesitation in recommending Locks and Alarms Ltd.

Locks and Alarms were recommended to me and I would also recommend them. They are incredibly courteous and professional. Jon came round promptly to assess my needs, patiently listened and answered all my questions, and he also gave me his recommendation. He sent through the quote quickly and the job was booked in and the installation went smoothly and completed on time. They consult and explain things all they way through the process, and in general just lovely people as well. Thank you Locks and Alarms.
During the last twenty years, I have periodically used the services of Locks and Alarms Ltd, for large jobs and small. I have always received great service and excellent workmanship. Neil and his sons are always polite, helpful and respectful when in and around my home. Whatever my requirements have been; Locks and Alarms Ltd have offered honest advice at reasonable prices. I will always recommend Locks and Alarms Ltd, to my family and friends.

Official checkOn the public register
Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 24 years on the register also points to an established business rather than a brand-new one.
