CCTV Drain Survey Before Buying | Is It Worth It
Buying a Solihull property? Find out when a CCTV drain survey earns its cost, what it uncovers, and what you risk skipping it.
A standard RICS homebuyer report won't touch the drains. The surveyor walks the garden, checks the roof, notes the damp. Then they close the gate and leave, and whatever is sitting in the pipework beneath that Dorridge semi or Knowle detached stays exactly where it is until it becomes your problem.
That's the gap a CCTV drain survey fills.
What a CCTV Survey Actually Does
An engineer runs a camera through the drainage system, typically from the nearest inspection chamber or gulley. You get a recorded video, a written report, and a condition grading on each section of pipe. The whole thing usually takes an hour on a standard residential property.
What turns up varies a lot by area. Older stock in Olton, Acocks Green and Hall Green tends to run on clay vitrified pipes from the 1930s and 40s. They crack. Tree roots find the cracks. In Dickens Heath, Monkspath and parts of Cheswick Green, the builds are newer but you still find poor-quality installation joints, displaced connections, and the occasional pipe that was never properly supported at build stage.
Common findings:
- Root ingress through joints (mature trees in Knowle and Bentley Heath gardens are frequent offenders)
- Cracked or collapsed sections on clay systems in B91, B92, B93
- Defective connections from a previous extension or ground floor conversion
- Shared runs that cross neighbouring boundaries, which complicates who pays for what
- Fat and grease build-up in kitchen lines on properties with no prior maintenance history
The Two Buyers Who Don't Need One
A new-build on a development in Marston Green or Chelmsley Wood, with a build warranty still live and no mature trees near the run. You're probably fine. The drains are under guarantee and the pipes are plastic.
Also: a straightforward terraced house in Shirley or Lode Heath, mid-century, where you're already stripping the place back to brick and you've priced a full drainage inspection into the build budget. If you're redoing the floors anyway, you'll find out what's there.
Everyone else. Read on.
When It's Worth Every Penny
| Scenario | Survey Worth It? | Reason |
|---|---|---|
| Pre-1970s property, clay pipes, mature trees | Yes, strongly | Root ingress risk is high; repairs are expensive |
| Detached or semi in Knowle, Dorridge, Hampton-in-Arden | Yes | Older infrastructure, large gardens, shared runs common |
| Any property with a history of slow drainage or past blockages | Yes | Symptom of structural problem, not just debris |
| Recent extension or loft conversion | Yes | Connection work often disturbs existing runs |
| New-build, plastic pipes, warranty active | Probably not | Risk is low; other checks matter more |
| Property you're gutting for full renovation | Judgement call | May find out anyway during works |
What Skipping It Costs You
A collapsed section of 100mm clay pipe needs excavating and replacing. Depending on depth, access and length, that job runs into four figures without difficulty. Root cutting and relining is a more contained cost, but still a surprise you don't want six months after completion.
More practically: if you find the defect before exchange, you negotiate. The seller fixes it, drops the price, or you walk. That leverage disappears the moment you complete.
I've spoken to buyers in Balsall Common and Catherine-de-Barnes who had surveys done after a slow drain appeared in the first winter. Both found cracked clay runs that predated their ownership by decades. Both wished they'd known before they signed.
The One Situation Where I'd Switch
If the vendor has a recent CCTV survey from a reputable company, say within the last 12 months, and you can see the footage and report, you don't need to duplicate it. Read the report properly, check the grading, make sure no remedial work was recommended and then quietly dropped. If it's clean and recent, that's good enough.
If they don't have one, don't assume that means there's nothing wrong. It usually means nobody has looked.
