DIY vs Professional Alarm Installation
What You Need to Know

The Case for DIY Alarms

We believe in honest advice, so let us be clear: DIY alarm systems are not worthless. Products like Ring, SimpliSafe, and Yale Smart Home have made basic security more accessible than ever before. They have a genuine place in the market.

DIY systems work well for rented properties where drilling holes and running cables is not practical. They provide a visible deterrent — and even a basic visible camera or siren deters most opportunistic burglars. For budget-conscious buyers, a basic DIY kit costs between £200 and £500, making it an affordable entry point. Setup is quick, typically under an hour, without needing to wait for an engineer appointment.

However, the limitations are real. Every sensor runs on batteries that need replacing — and when a battery dies, that zone is unprotected until you notice. DIY systems depend entirely on your Wi-Fi connection; if the broadband goes down or the signal is jammed, the system is compromised. Most home insurers will not accept a DIY system as meeting their alarm requirements. The hardware typically lasts 2 to 5 years before components fail. And the cloud subscription fees that many DIY brands charge (£3–£10 per month) add up over time — often exceeding the cost of a professional installation within a few years.

The Case for Professional Installation

Professional alarm systems like Texecom are designed for serious security — not just a visible deterrent, but a system engineered to detect, verify, and respond to genuine intrusions whilst minimising false alarms.

Insurance compliance is often the deciding factor. Many home insurance policies that specify alarm requirements ask for a system installed to EN50131 standards by an approved contractor. Without one, claims can be reduced or rejected entirely. A professionally installed Texecom system meets Grade 2 (domestic) or Grade 3 (commercial and high-value residential) standards as standard.

Professional monitoring provides a genuine safety net. Wilsons Systems arranges third-party 24/7 monitoring through established monitoring centres. When your alarm activates, trained operators verify the alarm, contact your keyholders, and where the system is graded appropriately, request police response. This happens whether you are at home, at work, or on holiday.

Reliability is built in from the ground up. Wired detectors never run out of batteries. Hardwired connections cannot be jammed or disrupted by Wi-Fi interference. The system continues to protect your property even during a power cut, thanks to built-in battery backup.

Engineered design makes a fundamental difference. When Wilsons Systems installs an alarm, we survey the property first. We design zone coverage to account for pet immunity, entry and exit routes, vulnerable areas, and the specific layout of your home. Every detector is positioned for optimal coverage — not just stuck on a wall wherever it is convenient.

Longevity is another key advantage. A well-installed Texecom system lasts 10 to 15 years or more with annual servicing. Compare that to 2 to 5 years for most DIY hardware. Smart features are not sacrificed either — the Texecom Connect app provides the same smartphone control as DIY systems, plus remote health monitoring via Texecom Cloud.

In our experience, many customers start with a DIY system and upgrade to professional within 2 to 3 years — usually after an insurance query or a reliability issue. Starting with a professional installation is almost always more cost-effective in the long run.
