Our Testimonials

"Delighted with the service from Alder Security. Explained what I needed in terms I could understand. Efficient, friendly and professional. Would highly recommend."

Angela August

"Can’t speak highly enough of Simon. He kitted our house out front and back, security and smoke detectors. We have cats so he found ways to secure the house without the detectors picking up our 4-pawed friends.
We now have remote control over our house, and fully understand it thanks to Simon taking the time to explain. Awesome service."

B.Blackmore, Henley

"Needed an Alarm Engineer to take over and subsequently maintain the installation. No problem for Alder Security. Totally competent."

Robert B, Abingdon

"Really impressed with Alder Security. Professional, courteous and prompt, Simon was able to identify, attend and solve the problem with our alarm system before other engineers had even returned my phone call. Thank you Simon, see you soon for our alarm takeover!"

Amanda Gregory, Didcot

"Excellent customer service from initial contact through to installing the alarm system and cameras and the after service. They made the whole process so easy and you could tell they are a hard working and solid team who take pride in what they do. We are so happy with the end result and would definitely recommend Alder Security to anyone thinking about having security."

"Hi Simon, It was a pleasure doing business with your company Alder Security. We were delighted with the CCTV installation work carried out on the house. You and your assistant Calum were a credit to your company having conducted yourselves in a very professional, knowledgeable and friendly manner and left everything neat and tidy upon completion. The results were excellent, and I would have no hesitation whatsoever in recommending the company to my colleagues and friends. "

Wanting to improve our home security we contacted Simon at Alder Security for advice and a quote. Simon Alder visited us and was really helpful in assisting us to select the system that best suited our needs. That was in terms of the areas covered by the sensors and, importantly for us 'non-techies', the ease with which the systems actually operated. Simon identified openly and clearly up front the benefits/dis-benefits of wireless and wired systems in our situation, and the cost implications of installing and maintaining the systems (replacement batteries, servicing, adding additional sensors if required for smoke and carbon-monoxide etc.). We had all the information we needed to make an informed decision on how to proceed. Installation was very painless, very well executed and explained, and we actually enjoyed the experience! Throughout we received a very helpful, considerate, professional and informative service and we would thoroughly recommend Alder Security to anyone.
