BS EN12566 Compliance: What It Means for Septic and Treatment Systems
When it comes to private drainage systems like septic tanks and sewage treatment plants, BS EN12566 is the standard that matters. It’s not just a technical specification — it’s a legal requirement tied to both Building Regulations and Environment Agency (EA) rules.
At Drain and Tank Solutions SW, we ensure that every system we install, inspect, or upgrade meets BS EN12566 standards — giving you peace of mind and full compliance during property sales or developments.
🧾 What Is BS EN12566?
BS EN12566 is a European standard that outlines how small wastewater treatment systems (up to 50 people equivalent) must be:
Designed
Tested
Installed
Operated
Maintained
It applies to:
Septic tanks
Treatment plants
Drainage fields and soakaways
Holding tanks and components
⚠️ “If your system is not BS EN12566-compliant, it may be illegal to sell the property or use the system as-is.”
🛠️ Why This Matters in Property Transactions
Many older or DIY-installed systems don’t meet this standard. During conveyancing, this can trigger:
Surveyor red flags
Mortgage lender concerns
Delayed or renegotiated sales
Demands for upgrades or replacements
We’re seeing more solicitors and buyers specifically request BS EN12566-compliant documentation.
