Heating Schema
Structured data for heating engineers and boiler installation businesses — using `HVACBusiness` schema with Gas Safe registration in `memberOf`, `hasOfferCatalog` for boiler installation and servicing, and `areaServed` for service area coverage.
Definition
`HVACBusiness` is the schema.org type for heating engineers, boiler installation companies, and HVAC contractors. Heating schema implementation: `@type: "HVACBusiness"`, with `hasOfferCatalog` listing boiler installation, boiler repair, boiler service/annual service plan, central heating installation, power flushing, gas safety certificate (landlord CP12), heat pump installation, radiator replacement. `memberOf` for Gas Safe Register registration: `{"@type": "Organization", "name": "Gas Safe Register"}` — the legal requirement for working on gas appliances in the UK, and the primary trust signal consumers verify. For MCS-certified heat pump installers, add `{"@type": "Organization", "name": "Microgeneration Certification Scheme (MCS)"}`. `areaServed` with `Place` objects for the service area; emergency boiler repair services should have `openingHoursSpecification` reflecting 24/7 or extended hours availability.
Why it matters for SEO
Gas Safe Register membership is a legal requirement for gas work in the UK — consumers increasingly verify Gas Safe registration numbers online before booking. Gas Safe reference in schema `memberOf` and visible on-page with a link to the engineer\'s Gas Safe record provides both semantic E-E-A-T signals and conversion-relevant trust display.
How DeepSEOAnalysis checks this
