Home Buyers Drain Survey in Derby

Why Drainage Is Not Covered in a Standard Survey

A homebuyer survey — whether RICS level 2 or 3 — does not include a CCTV drain inspection. Surveyors check visible drainage fittings but do not run cameras through the drain runs. A drain that looks fine at the inspection chamber can have root intrusion, a cracked section, or a displaced joint further down the pipe that will not become apparent until it blocks or causes a leak.

In Derby, this matters more than in newer cities. A large proportion of the city's housing stock was built before PVC drainage became standard. Spondon, Mickleover, Littleover, Normanton, Chaddesden, and the Victorian terraces across the city centre all have clay drainage that is 50–120 years old. Defects in clay drainage are common and repaired regularly — but you need to know about them before completion, not after.

What the Survey Checks

• Drain condition: The camera travels the full accessible drain run, recording the pipe condition, joint integrity, and bore clearance.
• Root ingress: Roots entering through cracked or displaced joints are clearly visible and recorded.
• Cracks and fractures: Hairline cracks in clay and defects in older concrete pipes are identified and their location recorded.
• Joint displacement: Offset or misaligned joints are flagged — these are root entry points and partial flow restrictions.
• Blockages and build-up: Any significant grease build-up or debris that is narrowing the bore is noted.
• Structural failures: Any collapsed or deformed section is located precisely.
• Mis-connections: Surface water and foul drainage connected incorrectly — relevant to planning and environmental regulations.

What You Receive

Following the survey you will receive:

• A written condition report in plain language, with each defect described and given a severity grading
• Indicative repair costs for any defects found
• The CCTV footage for your own reference and to share with your solicitor or surveyor
• A recommendation on whether any defect requires action before purchase

When to Book

Book once your offer has been accepted and you are in the conveyancing window — ideally before your solicitor receives the seller's property information form, so you can raise drainage-related queries early. If you are buying at auction, we can usually accommodate a survey at short notice before the auction date.

How Findings Support Negotiation

If the survey identifies a defect, you have options. A cracked clay joint that needs relining has a known cost. You can ask the vendor to fix it before completion, reduce your offer by the repair cost, or simply factor it into your budget with confidence. Most vendors will negotiate on confirmed findings. What you cannot negotiate on is a defect you do not know about.
