EN 806 & EN 12828 — drinking water and heating installations
What is it?
EN 806 governs drinking-water installations inside buildings (materials, hygiene, flushing, protection against backflow); EN 12828 covers the design of water-based heating systems (boilers, heat pumps, distribution, safety equipment).
What evidence should a candidate have?
Vocational plumber/heating diploma, pressure-test records, references naming system types (underfloor, heat pumps) and any gas-work authorisations.
Why it matters for staffing
Installers who hand over documented, pressure-tested systems reduce the client's warranty risk — evidence beats "years of experience" claims.
