What Affects the Cost?
Key pricing factors include system complexity (wireless vs. hardwired), number of entry points and zones, property size, and integration with smart home platforms. Labour costs are higher in West London due to demand and living expenses. Listed buildings or period properties may require specialist installation techniques, increasing costs. Monitoring service subscriptions, whether professional or app-based, vary by provider. Existing wiring can reduce installation time; new builds or extensive retrofits increase costs. Supply chain and equipment brand also affect overall pricing.
Money-Saving Tips
