Window Fitter SEO
SEO for window fitters and double glazing installers — FENSA registration (publicly verifiable, mandatory for building regs compliance), CERTASS, GGF membership, BFRC energy ratings, service-specific pages by window type and material, HomeAndConstructionBusiness schema.
Definition
Window fitter SEO targets homeowners planning to replace windows or doors. Primary query clusters: "window fitter [city]", "double glazing [city]", "replacement windows [city]", "uPVC windows [city]", "aluminium windows [city]", "bifold doors [city]". FENSA (Fenestration Self-Assessment Scheme) is the critical E-E-A-T signal: mandatory government-authorised Competent Person Scheme for replacement windows and doors in England and Wales; FENSA-registered installers self-certify building regulations compliance; public register at fensa.org.uk allows buyer verification; FENSA certificate is required at property conveyancing. CERTASS is the alternative government-authorised scheme. GGF (Glass and Glazing Federation) membership: trade body with code of good practice and consumer helpline. BFRC Window Energy Ratings (A++ to C) are increasingly important to energy-conscious buyers. Service architecture by material and style: uPVC (casement, tilt-and-turn, bay, sash, bow), aluminium (casement, bifold, sliding), timber sash (Victorian/Edwardian specialist), composite and uPVC doors, bifold and sliding doors, conservatories and orangeries, roof lanterns. FENSA certificate argument: when selling a property, conveyancers require building regs compliance evidence for windows replaced since 2002 — FENSA certificate satisfies this automatically.
Why it matters for SEO
FENSA is the most powerful E-E-A-T signal in the window fitting trade because it is mandatory, publicly verifiable, and has direct financial consequences for homeowners at property sale. A FENSA-registered installer can make a specific, verifiable claim — "we are FENSA-registered, you can verify our status at fensa.org.uk, and your FENSA certificate satisfies conveyancing requirements automatically" — that unregistered competitors cannot.
