Choosing an Access Control Installer: The Verification Checklist

The four-filter verification

• 1. Certification registers: SSAIB/NSI listings with access control scope — independent audit of installations, insurance, complaints handling (the same institutional logic as alarm installers; one-minute lookups, including ours: 13629)
• 2. Platform accreditation: Paxton registered/Salto certified/etc. — manufacturer training, warranty enhancements (Paxton's installer-tier warranties reward it), and tech-support escalation when oddities arise; ask which tier and since when
• 3. Fire/egress competence: the questions that sort joiners-with-readers from system installers — 'how do escape doors fail?', 'where does the fire alarm interface?', 'who tests release at commissioning?' (answers per the fail-safe guide should flow without pauses)
• 4. Quote forensics: door schedule with lock families per door, credential specification (DESFire stated — the cloning question answered in writing), GDPR setup, training and maintenance lines (the per-door guide's decomposition as your audit grid)

Red flags, sector-specific

Beyond the universal trades warnings (no address, cash pressure, today-only pricing): credential complacency ('fobs are fobs' — the legacy-125kHz upsell-avoidance that costs you a cloning migration later); fire-release improvisation (relays without alarm interfaces, fail-secure on escape routes 'for security' — disqualifying, not negotiable); platform promiscuity without depth (seven logos, zero accreditations — jack-of-all-systems estates age badly); database cavalierness (your staff PII on their laptop sans agreement — GDPR processor obligations are real; the GDPR guide's questions apply to installers too); and handover hoarding (admin passwords retained, programming undocumented — orphaned-system insurance for them, hostage-taking for you; demand credentials-and-documentation handover contractually). The pattern underneath: access control sits between trades — electrical, joinery, IT, life-safety — and bad installers are whichever single trade learned readers; good ones respect all four.

Comparing bids and protecting the decision

Process that works: like-for-like briefs (door schedule, platform preference or open, credential standard named) to 2–3 register-verified bidders; whole-life comparison (the 5-year discipline — licences, maintenance, credential churn — per the cost guide's tables); reference calls in your sector (multi-tenant, schools, gyms — vertical fluency shows, per those guides); and contractual hygiene (commissioning criteria including fire-release testing, documentation deliverables, warranty terms, maintenance pricing locked at sale). Weight after-sales reality heavily: access systems live 10–15 years through staff churn, door wear and platform updates — the installer relationship is the product's second half. Our pitch reduces to the checklist itself: verify us against every line (SSAIB 13629, Paxton-accredited, fire-release answers on tap, decomposed quotes as standard) — then hold every bidder to the same light.
