Drainage Investigations

CCTV Drain Surveys

Pre-purchase drain surveys and diagnostic CCTV inspections across Hertfordshire, Buckinghamshire & Bedfordshire.

Know Exactly What's
Beneath The Ground

A CCTV drain survey is the quickest and most reliable way to inspect the internal condition of a drainage system. Using a high-resolution push-rod camera, we visually inspect pipework, identify defects, and provide a clear diagnosis rather than guesswork.

We regularly carry out pre-purchase drain surveys for home buyers and their solicitors, along with diagnostic surveys for recurring blockages, suspected damage, root ingress and pre-construction investigations.

Need to establish the pipe route as well as its condition? Read how underground drains are traced.

Types of Survey

Choose the Right Level of Survey

Published prices are starting prices. The right level is confirmed with you before booking.

CCTV Drain Survey — No Formal Report

From £200+ VAT

For straightforward or reactive drainage problems where you primarily need the drainage inspected, the problem identified and practical advice provided.

  • CCTV drain inspection
  • Basic drainage investigation
  • Verbal explanation of findings
  • Practical recommendations

Ideal for blockages, recurring drainage problems, suspected defects and straightforward diagnostic investigations where a formal written report is not required.

CCTV Drain Survey With Written Report

From £350+ VAT

For customers requiring a documented assessment of the drainage condition.

  • CCTV drain inspection
  • Drain condition assessment
  • Relevant CCTV images/stills
  • Written findings
  • Recommendations

Suitable where a permanent written record of the drainage condition and findings is required — for example prior to remedial works, property works or for general condition assessment.

Complex / Technical Drainage Investigation

From £650+ VAT

Where the purpose of the investigation extends beyond a standard CCTV condition survey, the work is treated as a Drainage Investigation & Technical Report and priced accordingly.

  • Drainage tracing
  • Unknown layouts & buried chambers
  • Multiple drainage branches
  • Controlled flow testing
  • Detailed technical reporting

Scoped individually before booking. Investigations required by Building Control or another third party are priced separately from a standard CCTV survey.

Buying a property with a septic tank, treatment plant or other off-mains drainage? Our Private Drainage & Wastewater Surveys combine CCTV inspection with a wider assessment of the property's drainage arrangements.

A property with a septic tank or treatment plant may require a wider assessment than CCTV alone. Read our guide to buying a property with private drainage.

Is the investigation for Building Control or another professional third party?

If the investigation or report is required by Building Control, a solicitor, architect, engineer, lender, buyer, water company or another third party, please tell us before booking.

These investigations can require additional site investigation, evidence gathering, drainage tracing, regulatory assessment and technical reporting and are therefore scoped and priced separately from a standard CCTV drain survey.

What We Use CCTV For

Every Use Case,
One Camera

CCTV drain cameras are one of the most versatile tools in modern drainage. Here are the situations we're regularly called out for across Hertfordshire, Buckinghamshire and Bedfordshire.

Pre-Purchase Home Buyer Surveys

One of our most common enquiries. Buyers, solicitors and surveyors request a CCTV survey before completion to check the condition of the drainage, confirm it isn't shared, and flag any defects that could affect the property's value or future maintenance costs.

Blockage & Fault Diagnosis

Locating blockages, identifying the exact cause and pinpointing the fault so remedial works can be targeted — no unnecessary digging or guesswork.

Collapsed or Damaged Pipework

Confirming suspected pipe collapses, fractures, displaced joints, poor falls or misaligned connections before quoting for repair or replacement.

Root Ingress Investigations

Identifying tree root intrusion into clay or old drainage runs and mapping how far the ingress extends so a permanent fix can be planned.

Drain Tracing & Mapping

Tracing hidden or forgotten drainage runs, locating chambers, determining depths and mapping how a site actually drains — essential before any groundworks.

Pre-Construction & Extension Surveys

Surveying existing drainage before extensions, driveways, patios or groundworks so runs can be protected, diverted or upgraded before build.

Septic Tank & Treatment Plant Diagnostics

Inspecting pipe runs into and out of septic tanks, treatment plants and cesspits — vital for diagnosing tank problems, blockages and pre-purchase off-mains surveys.

Consultancy Evidence & Strategy

Used alongside our drainage consultancy to gather visual evidence, verify existing drainage assumptions and build accurate surface water and foul drainage strategies.

Insurance Claims & Disputes

Documented CCTV footage, still images and written reports suitable for insurers, solicitors and party wall or boundary disputes.

Recurring or Unexplained Problems

For drains that keep blocking, smelling, backing up or flooding — a CCTV survey removes the guesswork and identifies the underlying cause.

Shared Drainage Verification

Confirming whether drainage is shared with neighbours or connects to a private system — a common concern for buyers and conveyancers.

Commercial & Developer Surveys

Site-wide CCTV inspections for commercial properties, landlords and developers as part of due diligence, planning or drainage strategy work.
