Non-compliance is a serious issue that can lead to:
The first step to protecting yourself is a professional assessment.
We do the complex legal checks for you — saving you time, money, and stress.
Our Septic Tank Survey and Compliance Report covers every detail required under the UK General Binding Rules (GBRs) — ensuring your system meets Environment Agency standards.
Your personalised report gives you a clear answer on whether your sewage or septic system is fully compliant, and provides expert guidance on what to do if it isn’t.
Here’s what’s included:
✅ Daily Discharge Check – We calculate your daily sewage discharge volume based on your property details (number of bedrooms, discharge type, and system size) to ensure it stays within legal limits.
✅ Discharge Location Review – We confirm whether your system releases wastewater to ground or surface water, as required by the Environment Agency’s General Binding Rules.
✅ Environmental Sensitivity Assessment – We identify if your property lies near sensitive or protected zones such as:
Groundwater Source Protection Zones
Registered Boreholes
Special Areas of Conservation (SACs)
Special Protection Areas (SPAs)
Sites of Special Scientific Interest (SSSIs)
Ramsar Sites
Recorded Chalk Rivers
Ancient Woodlands
If your property falls within one of these zones, you may need an Environment Agency permit — and our report makes that clear.
✅ On-Site Checks & Guidance – You’ll also receive a simple, practical checklist of on-site checks you can perform to stay compliant, avoid costly system upgrades, and prevent legal or property sale issues later on.
