AOT Trinity: PUB-Verified Compliance at Competitive Pricing
AOT Trinity offers PUB-verified compliance (Licence WS16882018) at competitive pricing with faster same-day response than many larger providers. The company also holds BCA registration (ME01 (Air-Con/HVAC), ME06 (Fire Prevention), ME12 (Plumbing/Sanitary)) and BiZSAFE Level 3 certification, giving customers a documented safety and compliance trail in addition to price transparency.
How to Choose Between These Providers
- Check the PUB licence number directly — do not rely on marketing claims alone.
- Compare like-for-like quotes — tank size, access difficulty and disinfection method affect price.
- Ask about BCA and BiZSAFE status — this indicates safety management maturity for on-site work.
- Confirm response time in writing before booking, especially for urgent/emergency requests.
