What Are Pre-Purchase Surveys?
A pre-purchase survey is a specialist inspection of a property’s underground drainage system, carried out before contracts are exchanged. Unlike standard building surveys, these investigations identify the true condition of pipework, soakaways, septic tanks, and treatment systems, providing a detailed picture of performance, projected lifespan, and compliance.
A typical pre-purchase survey includes:
- CCTV Drainage Inspection – High-definition camera equipment used to assess the internal condition of pipes
- Mapping & Tracing – Recording the route and depth of drainage runs for accurate reporting
- Structural Assessment – Identifying fractures, root intrusion, blockages, or misaligned joints
- Condition Grading – Categorising defects according to severity and urgency
- Recommendations Report – Supplying a full written summary with photographs, diagrams, and professional advice
Our drainage surveys provide a clear, technical overview of a property’s wastewater infrastructure, empowering buyers to make informed, confident decisions.


Why Home Buyers Surveys Are So Important
A drainage system is hidden from view, yet it’s one of the most important parts of any property. For homes with off-mains foul drainage, a detailed inspection is essential to verify compliance with the Environment Agency’s General Binding Rules and to avoid unexpected remedial costs further down the line.
Home buyers surveys from Smart Drainz protect your investment and highlight potential risks before purchase. Afterall, issues such as cracks, collapsed sections, or outdated septic tanks can lead to pollution, property damage, or enforcement action if left unchecked.
The benefits of a drainage survey before purchase include:
- Early Fault Detection – Preventing costly post-sale surprises
- Regulatory Compliance – Confirming adherence to environmental and building standards
- Negotiation Leverage – Using verified data to adjust purchase offers or request repairs
- Peace of Mind – Knowing the property’s system is safe and fully functional
As a specialist drainage contractor, Smart Drainz delivers the insight and technical precision that general property surveys often miss.
