What is a site assessment for a septic installation?
Our free site assessment tells you exactly where you stand — whether you're planning a new residential septic system or wondering if your existing one meets regulations.
We visit your property to determine what your site can support, what regulatory requirements apply, and — if you already have a system — whether it complies with the rules currently in force.
Our visit covers:
- Regulatory eligibility check
We confirm whether a new or existing system meets the Environment Agency's General Binding Rules, and whether a full Environmental Permit will be needed. - Groundwater Source Protection Zone search
We identify any environmental restrictions that could affect the location or type of system on your property. - Existing system compliance check (where applicable)
If you already have a system, we assess it — whatever the make or brand. We'll confirm whether it meets current regulations, including the General Binding Rules introduced in 2020.
How we conduct our free site assessment
Our site assessment covers any residential property — whether you're planning a new septic system, replacing an existing one, or simply not sure where to start.
Here's how it works:
- We visit your property
One of our experienced specialists visits your site at the agreed time. - We carry out our checks
We assess your property against the Environment Agency's General Binding Rules, check for Groundwater Source Protection Zones and nearby watercourses, and — if you have an existing system — confirm whether it meets current regulations. Everything is covered in a single visit. - We walk you through our findings
Once the visit is complete, we explain what we found in plain language and advise on the most appropriate next steps for your situation.
A free service with real value
Our site assessment is free of charge. There is no hidden cost and no obligation to proceed after the visit.
Here's what you get with our assessment:
- confirmation of whether your site is eligible for an off-mains system
- a clear understanding of any environmental restrictions that apply to your property
- honest, expert advice on your next steps
- a team who can handle your installation from beginning to end, if you choose
Following the assessment, we may recommend soil testing to complete the picture of what your property can support.
Soil testing is a separate, chargeable service. We'll walk you through what's involved and give you a clear quote before anything proceeds.
