Quality Controls & Certifications
HMK designs, manufactures and supports products under rigorous quality controls. This page summarizes our standards, safety testing, assurance on reconditioned units, and insurance coverage. (Details can vary by model and region.)
HMK standards & assurances
Core assurances
- Full installation by trained HMK engineers.
- Comprehensive 12-month guarantee (extendable).

All findings are recorded and only units that pass every item are released to customers.
Safety testing & endurance
During design and verification, prototype stairlifts for curved/landed staircases undergo extended travel endurance (hundreds of kilometers cumulatively), repeated start/stop cycles, and functional testing of standard and optional features (powered swivel, remotes, hinged/slide tracks, child-lock, etc.). The goal is predictable performance and safe operation over years of use.
Insurance & liability
Coverage
- Public/Product Liability Insurance for installations and service.
- Installation works insurance (where required).
- Job-specific risk assessments and method statements.
Documents
- Insurance certificate available on request (region-specific).
