Domestic Installation Schema
Schema.org `Service` objects within `hasOfferCatalog` for domestic installation services — covering EV charger installation, solar panel installation, heat pump installation, smart home wiring, and other regulated home installation services with certification-relevant content.
Definition
Domestic installation schema covers `Service` objects declared within an `Offer/hasOfferCatalog` structure for residential installation services. Each domestic installation service type benefits from a dedicated `Service` object rather than a generic service name: `{"@type": "Service", "name": "EV home charger installation", "description": "OZEV-approved 7kW EV charging point installation with smart charging capability"}`. For regulated domestic installations, the `Service` object can include `provider` referencing the installer\'s certification: relevant properties for EV charger installation include OZEV-approved status; for heat pump installation, MCS certification; for solar PV installation, MCS certification and SEG registration; for gas appliance installation, Gas Safe registration. The `hasOfferCatalog` approach allows a single contractor website to clearly delineate specific installation services for Google\'s semantic matching, enabling better query-to-service alignment for long-tail installation queries ("7kW EV charger installation cost [area]", "heat pump installer [city]", "solar panel installer [area]").
Why it matters for SEO
Domestic installation services typically have high transaction values (£500-£10,000+) and strong OZEV/government grant dimensions that create qualified traffic. Specific service-level schema objects improve semantic matching precision for installation-specific queries and enable richer local pack result displays for the specific installation service type.
How DeepSEOAnalysis checks this
DeepSEOAnalysis validates `Service` object completeness within `hasOfferCatalog`, checks for service-level descriptions that support semantic matching, and confirms all `Offer/Service` schema is server-rendered.
