Hidden Drainage Defect in Bromley Leads to Legal Notice – How a CCTV Inspection Prevented Escalation

When purchasing a property in Bromley, it’s easy to focus on what’s visible — the layout, the finish, the structure. But what’s happening underground can be far more serious.
This case study highlights exactly why a Homebuyers CCTV Camera Condition Inspection Package is not just a recommendation — it’s protection.

The Initial CCTV Inspection in Bromley
We were instructed to carry out a Homebuyers CCTV Camera Condition Inspection Package at a residential property in Bromley prior to purchase.
During the inspection, we identified that the property had:
A separate foul water system and surface water system
An issue where a foul waste pipe was not connected to the accessible foul drainage system
Instead, the waste had no confirmed lawful discharge route.
This was clearly documented in our:
Full written report
CCTV footage
Computerised drainage layout drawing
We recommended further investigation to trace and correctly connect the pipework.
The Risk Highlighted (But Not Acted On)
Despite our findings being clearly outlined, the issue was not investigated further after purchase.
This is more common than many homeowners realise — drainage issues are often deprioritised once a sale completes.
However, in this case, the consequences were significant.
One Year Later – Enforcement Action
Approximately one year after purchase, Thames Water became aware of the issue during their own investigations.
They determined that:
Foul waste from the property was discharging into a nearby stream
This constituted an unlawful connection and environmental breach
As a result, the homeowner was:
Served with a 28-day legal notice
Required to rectify the issue immediately
At risk of legal proceedings if no action was taken
Emergency Call Back – Immediate Action Required
Following the notice, we were contacted urgently to resolve the issue.
Our team:
Carried out further investigation to locate the defective connection
Identified the correct point of connection within the foul system
Installed a new connection to ensure all foul waste discharged correctly into the main sewer system
This brought the system back into compliance and prevented further escalation.
Why This Matters for Homebuyers in Bromley (and Across London)
This case highlights a critical point:
A drainage issue doesn’t disappear — it simply becomes your responsibility after purchase.
Had the recommendation from the original CCTV inspection been actioned:
The issue could have been resolved in a controlled, non-urgent manner
The homeowner could have avoided legal pressure and tight deadlines
Costs and disruption would likely have been significantly reduced
