WRc-compliant CCTV reports are what solicitors require during property purchase. Most drainage firms can't produce them.
WRc's Manual of Sewer Condition Classification 5th edition (MSCC5) is the standard CCTV survey report format accepted by water companies, local authorities, solicitors, and home-buyer surveys. CON29DW water searches during property purchase explicitly require WRc-compliant reports.
Most drainage firms produce informal reports that solicitors reject. The ones who deliver WRc MSCC5 reports become the preferred local supplier for surveyors and conveyancers. We surface 'WRc-approved reports' prominently, and rank you for the searches solicitors actually do.
