The Rules Have Changed. Is Your Septic Tank a Liability?

The Environment Agency’s General Binding Rules (GBR) for small sewage discharges are now in full effect. If your septic tank discharges into a watercourse like a river or stream, it is no longer compliant.

Non-compliance is a serious issue that can lead to:

  • Significant Financial Penalties: The Environment Agency can issue substantial fines for non-compliant systems.
  • Failed Property Sales: Solicitors and conveyancers now require proof of compliance. A non-compliant tank can halt a sale, costing you time and money.
  • Environmental Damage: An outdated system can pollute local waterways, harming wildlife.

The first step to protecting yourself is a professional assessment.

🧾 What’s Included in Your Septic Tank Survey & Compliance Report

We handle the legal checks, so you don’t risk fines, delays, or costly mistakes.​

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.
