Every contract is predicated on a baseline CCTV survey, providing a WRc-style classified condition report that establishes a forensic record of your drainage network's integrity for compliance and transactional due diligence.

This procedural, evidence-led approach is designed for landlords, commercial property managers, and conveyancers who require unambiguous documentation to support insurance claims, leasehold obligations, and property transactions.

Pricing is structured based on the diagnostic baseline survey findings and the agreed schedule of proactive inspections and priority-response interventions, tailored to your asset's specific risk profile.

Baseline CCTV Survey & WRc Defect Schedule: A comprehensive diagnostic record classifying defects to industry-standard codes, forming the evidential foundation for all works.
Scheduled Diagnostic Re-inspections: Periodic CCTV surveys monitor defect progression and verify post-intervention efficacy, generating sequential documentation for asset history.
Priority Response Based on Defect Severity: Work scheduling is determined by the classified defect risk, ensuring critical issues are addressed with appropriate urgency to protect asset integrity.
Evidence Pack for Insurance & Legal: All works are supported by before-and-after CCTV footage, stills, and detailed reports, creating a robust evidence pack for claims or disputes.
Proactive Blockage & Infiltration Mitigation: Analysis of defect data allows for targeted, preventive interventions to avoid unscheduled blockages or structural water ingress.
Conveyancing-Compliant Drainage Certificates: Provide definitive, survey-backed drainage certificates for property transactions, satisfying solicitor enquiries and due diligence requirements.

How it works

A method, not a guess

Diagnostic Baseline Survey

A full system CCTV survey is conducted, with all defects classified to WRc standards. This report forms the contract's evidential benchmark and scope of works.

Contract Scope & Schedule Agreement

We agree a maintenance and inspection schedule based on the defect classification, prioritising structural and operational risks, with defined response protocols.

Scheduled Re-inspection & Documentation

At agreed intervals, CCTV re-inspections are performed. Comparative reports document defect progression or resolution, providing an ongoing audit trail.

Evidence-Based Remedial Works

Any necessary works are executed with full photographic and CCTV documentation, referencing the original defect codes to close the procedural loop.

Questions

Commercial Contracts FAQs for London homeowners

How does a diagnostic contract differ from a standard maintenance agreement?

Standard agreements are often reactive. Our contracts are built on a documented, diagnostic baseline (CCTV & WRc report), enabling proactive, evidence-based management with a full audit trail for compliance and legal protection.

What is WRc defect classification and why is it important?

WRc is the industry standard for categorising drainage defects with precise codes (e.g., fractures, infiltrations, deformations). It provides unambiguous, technical terminology for reports, ensuring clarity for engineers, insurers, and legal professionals.

Can the documentation support a property transaction?

Yes. The baseline survey and subsequent reports provide the definitive evidence required for solicitor drainage enquiries, often supplied as a formal drainage certificate to satisfy conveyancing due diligence.

How are emergency call-outs handled under the contract?

Emergency responses are integrated into the schedule based on the severity of diagnosed defects. All emergency works are fully documented with CCTV evidence, linking directly back to the asset's condition history.

Is the initial CCTV survey included in the contract cost?

Yes. The diagnostic baseline survey is the foundational element of the contract and is included, providing the classified condition report that determines the ongoing scope and priority of managed services.
