A glazier website operates in a trade where the regulatory framework (FENSA, CERTASS, Building Regulations Part L) is structural, the customer search intent splits sharply between emergency (smashed glass after dark) and considered (full window replacement in three months), and the local-pack competition includes both independents and the national-chain glazing brands. Properly-built sites surface the FENSA/CERTASS registration prominently, explain Part L self-certification in plain English, and capture both search-intent audiences with separate paths.
What is different about glazier websites
Three things make glazier web design distinct from other trades. First, the FENSA/CERTASS competent-person scheme is structurally important — it handles Building Regulations Part L self-certification for replacement windows, saves the customer Building Control fees, and produces documentation the property carries forward at resale. Templated sites that hide the registration lose the customer who has done thirty seconds of research. Second, the emergency vs replacement search intent split is operationally critical — emergency customers need tap-to-call above the fold, replacement customers need survey-scheduling. Third, the window-type specialism landscape (uPVC, aluminium, timber sash, secondary glazing, conservation) is meaningful — customers know which product they want before they enquire and templates that conflate all of them confuse the search ranking.
What we ship for a glazier
A bespoke glazier website with the emergency vs replacement service split, window-type specialism landings for each product the firm offers, FENSA / CERTASS / GGF / BFRC credentialing panel, Building Regulations Part L self-certification narrative, energy-rating transparency, the standard contact and service-area block, and the full HomeAndConstructionBusiness + LocalBusiness + Service schema graph.
The FENSA / CERTASS credentialing in detail
FENSA (Fenestration Self-Assessment scheme) — the largest UK competent-person scheme for window and door installation, operated under the Glass and Glazing Federation. FENSA-registered installers are audited on installation standards, customer-care procedures, and Building Regulations compliance, and gain the authority to self-certify replacement window installations under Part L. CERTASS — alternative competent-person scheme with equivalent regulatory standing, operated by Certass Ltd. Glass and Glazing Federation — the trade body with broader membership covering manufacturers and installers. BFRC (British Fenestration Rating Council) — the energy-rating certification body. Each credential is rendered with the membership number, verification link to the relevant public register, and proper schema-level propertyValue entry.
The Part L self-certification narrative
A dedicated section explaining Building Regulations Part L compliance in plain English. Part L sets thermal-performance standards for replacement windows in existing homes (typical U-value 1.4 W/m²K or better, Window Energy Rating Band B or equivalent). Replacement windows installed since April 2002 require compliance documentation; without it the property can face issues at resale or remortgage. The two compliance routes: FENSA/CERTASS-registered installer self-certifies (no Building Control fee, FENSA certificate issued to customer); non-registered installer requires customer-paid Building Control sign-off (typical fee £150-£400 per installation). The FENSA route is the standard modern UK approach and the website explains the customer-side saving clearly.
The window-type specialism landings
uPVC casement (the volume product, typical price £400-£900 per window installed including frame, glass, fitting and Part L documentation). uPVC sash window (traditional sash visual with modern uPVC frame, £700-£1,400 typical). Aluminium bi-fold doors (the premium garden-side product, £4,000-£12,000 per door set depending on size and configuration). Timber sash window (heritage-compatible replacement for period properties, £1,200-£2,800 per window). Secondary glazing (for listed buildings where replacement is not permitted, retrofit-internal glazing with thermal benefit but without altering the primary window). Conservation-area replacement (timber-frame replacement complying with conservation-area constraints). Roof lanterns and roof lights (typically Velux for standard rooflights, bespoke aluminium lantern lights for premium kitchen extensions). Each landing carries proper Service schema and indicative pricing.
What we deliberately do not build
No bespoke window-configurator tool — the major manufacturers (Anglian, Everest, Origin) ship configurators but they do not lift independent-glazier conversion; the survey conversation is the real configuration. No live-chat — the considered-quote audience does not respond to it. No "smart-glass IoT" gimmick — the market is not yet at scale and the brand cost of overclaiming is real.
Pricing for a glazier website
Most independent single-team glazier firms land on Launch (£499) — the standard architecture with emergency-and-replacement split, window-type landings, FENSA credentialing, Part L narrative and schema. Multi-team firms with separate domestic and commercial divisions or firms with specialist heritage divisions move to Growth (£899) for the multi-division architecture. Pro (£1,499) is for premium aluminium-bi-fold and roof-lantern specialists working at the £30,000+ project tier where the editorial content layer (named-project case studies, manufacturer-partnership detail) justifies the deeper architecture.
