A pre-purchase drain survey is a CCTV inspection commissioned by a prospective buyer, or their solicitor, to identify any significant drainage defects before exchanging contracts. The survey covers the lateral drain and accessible private drainage on the property, with footage recorded for review. The resulting report grades defects against the WRc Manual of Sewer Condition Classification and BS EN 13508-2, providing context for negotiation and budgeting. The survey is particularly valuable for older North London terraces with original Victorian clay drains, properties extended over historic drain runs, and homes near mature trees where root ingress is likely. Engineers carry out the inspection in accordance with industry practice and provide a clear written report. The findings can also inform insurance disclosure and assist in arranging appropriate maintenance after completion.
