Require NAS-Certified Contractors
Across Your FM Supply Chain.
Facilities management clients, estates managers, and property owners are accountable for who accesses their buildings and how they operate. NAS gives you independently assessed, publicly verifiable contractor compliance — covering the COSHH, GDPR, and H&S obligations that FM procurement can't afford to get wrong.
Why Require NAS From Your FM Contractors?
FM clients are accountable for contractor conduct across multi-site estates. A contractor COSHH breach, GDPR incident, or H&S failure on your premises is your liability too — especially if you cannot evidence prior due diligence.
The Risk Without It
Why Requiring NAS Protects You
How NAS Works For You
Independent, evidence-based contractor certification you can rely on.
Instant Register Search
Verify any FM contractor free on the NAS public register — by name or certificate number, no login needed.
Evidence-Based Assessment
Every NAS certificate is backed by independently reviewed documentary evidence — not just a self-completed form.
COSHH & H&S Covered
NAS Silver and above independently assess COSHH and Health & Safety at Work Act compliance — essential for hard FM services.
Environmental Protection at Gold
NAS Gold covers Environmental Protection Act — critical for FM contractors handling refrigerants, controlled waste, and site pollution.
Always Current Credentials
Annual NAS renewal means the public register always reflects live contractor compliance status — expired certificates are immediately flagged.
Multi-Site Due Diligence
Manage FM supply chain compliance across large estates with consistent, independently verified contractor credentials on a single register.
