  • Many thanks for a “Prompt, Polite & Efficient” service!”
    SO & E Motorcycles, Sleaford
  • This is an email to say how impressed I am with your men today! The job went smoothly and I was pleased to see the men were well trained too (tidy, hoovered up & put used cups in sink!), a rarity these days, a pleasure to have in your home when sometimes it’s quite an intrusion.
    Mrs D, Barrowby
  • We received a most professional service when we had our house alarm fitted. The engineer arrived on time and obviously knew the system inside out. The fitting was conducted quickly and our home left clean and tidy upon completion. The system has worked perfectly since installation. We wouldn’t hesitate to recommend to family and friends (and indeed have done so).
    Mr & Mrs Bradford, Mansfield
  • I have worked with A1 Security Services for the last 10 years. We have their alarm system on both our school premises. The company are a local firm which offers you that personal touch. They are all friendly, helpful, will always put the customer first and are always on hand night or day. I would highly recommend this company to others.
    Sally Hearn Site Manager
  • Fantastic service provided by this company. I emailed them showing interest, I received a call back very quickly to discuss an appointment to see me and make recommendations, this happened as punctually as described with a courtesy call before to confirm. Details and appointments for installations made, the engineer arrived on time, was helpful, installed as described and spent time explaining the system. I would have no hesitation in recommending this company!
    Mr T, Spalding
  • We just wanted to say thank you for the work carried out on our intruder alarm system and what a good job Ady has done for us. He carried out all the work in a most pleasant and professional manner. He is an excellent representative for your company.
    Mr B - Allington
  • Thank you for attending to our alarm box issue. It was very reassuring that you listened to us and responded as you did. We’ve been very happy indeed with both the alarm system and the customer service you have given to us. This is why we decided to go with a local company in the first place and avoid the big household names. They can never compete with a properly run local business.
    Mr E - Colsterworth
