Common questions from London homeowners and business owners considering Ajax. Have a question we haven't covered? Get in touch.
A typical 3-bed installation with Hub G3, 4-6 motion sensors, door contacts, keypad, outdoor siren, and key fobs costs £1,800-£3,000 fully installed. Simpler flat installations can start from £699. Commercial installations are custom quoted after a free site survey based on the number of zones, devices, and integration requirements.
Each has strengths. Ajax leads on wireless performance, photo verification, and app experience — it feels like a modern connected product. Pyronix and Texecom are excellent wired alarm systems with proven reliability and strong UK trade support for service and upgrades.
We're authorised installers for all three and recommend based on your specific situation. If you want the most modern experience with photo-verified alerts, Ajax is the answer. If you have an existing Pyronix or Texecom system, we can often upgrade rather than replace.
Yes. Ajax's Jeweller wireless protocol has up to 2,000m range in open space and penetrates brick, stone, and solid walls effectively. During our site survey we test signal strength at each planned device location and add range extenders (ReX) where needed. For particularly challenging properties like converted barns or double-thickness stone walls, Ajax Fibra (wired) is an alternative that uses the same app and components.
A typical 3-bed house with a Hub, 4-6 sensors, keypad, and siren is fitted in 3-5 hours. Larger homes (5+ bed) typically take half a day. Commercial sites and Fibra wired installations can take a full day or more depending on cable runs and device count. Because Ajax wireless devices mount with no drilling required, installation causes no disruption — you can continue using your home throughout.
Ajax Superior devices meet EN 50131 Grade 2 and Grade 3 standards — the highest grades for commercial and high-risk properties. The range is also INCERT, SSF, and PD 6662:2017 compliant. Grade 3 certification is typically required for high-value residential, jewellers, pharmacies, cash-handling businesses, and insurance-specified commercial installations.
Both are possible. The Ajax app gives you full control for free — arm, disarm, photo-verified alerts, event history, and instant push notifications. Many homeowners find this sufficient.
Professional ARC (Alarm Receiving Centre) monitoring is optional and typically costs £20-30/month. ARC monitoring is often required by insurers for high-value properties, and delivers a verified police response capability. If you're unsure, we can advise during your free survey based on your insurance requirements and risk profile.
Absolutely — this is one of Ajax's major strengths. The system is fully modular. You can add Ajax DomeCam or TurretCam for full CCTV integration, Ajax FireProtect smoke and heat detectors for fire detection, LeaksProtect for water leak detection, and automation devices like WallSwitch and Socket. Every new device appears in the same Ajax app alongside your existing setup. Most additions take under an hour per device.
