CCTV Drain Surveys in Hayes: Advice & Costs
A CCTV survey is the diagnosis step — the point is not the camera footage but the graded report that tells you exactly what, where and how bad, so repair quotes compete on the same facts.
What a survey involves
- A pan-and-tilt camera run through accessible drain runs
- On-screen distance logging against a site sketch
- Defect coding to industry standard (structural and service grades)
- A recorded video plus a written report with recommendations
When a survey pays for itself
- Before buying an older property
- When the same run keeps blocking
- Before accepting any excavation quote
- When planning an extension near existing drains
Reading your report: a worked example
Three real-style lines decoded: “4.2m — DER — deposits, 20% — grade 2” means a fifth of the bore silted four metres in: clean, don’t repair. “7.8m — JDM — joint displaced medium — grade 3”: a planned patch. “11.5m — RI — roots intruding — grade 4”: cut and line this season. Ten minutes with the code sheet and you can hold your own with any contractor.
Negotiating as a homebuyer
Grade 3+ findings plus a repair quote give you a figure to negotiate with: ask the seller to fix with proof before exchange, or chip the price by the quote. A survey ordered by you answers to you — the report is yours to use in the negotiation.
Who should carry out the survey
Incentives shape reports: a survey from the firm hoping to sell the repair leans, however honestly, toward finding one; a survey you commissioned independently answers only to you. Neither is dishonest — repair firms include skilled, scrupulous surveyors — but on purchases, insurance disputes and second opinions, independence is worth insisting on. The practical test of any surveyor, attached or not: do you receive the full coded report, the footage and the plan, regardless of whether you buy anything else? If the document only exists when the repair is agreed, it was marketing material rather than a survey.

Common questions
What does a survey cost here?
Standard domestic surveys typically run £90–£250, homebuyer surveys with full reports £150–£400 — access and length move the number.
What should the report include?
WRc-standard defect codes, positions and depths, a recording, and a layout sketch. If a quote offers less, it is an opinion, not a survey.
Survey first or clear first?
If the drain is blocked solid, a clearance comes first — cameras need to see. Combined visits are common and worth requesting.
How recent must a survey be for a lender or buyer?
Practice says months, not years — three to six is comfortably current. Anything older invites the question of what has moved since.
The seller won’t allow a drain survey — red flag?
Sometimes the reason is innocent; sometimes the seller knows something. Make the offer conditional or price the uncertainty — never just shrug it off.
