Why You Need a CCTV Drain Survey Before Buying a House
Homebuyer Drainage Advice
Buying a house is one of the most significant investments you will ever make. You've likely arranged a comprehensive building survey to check the roof, the walls, and the damp. But what about the infrastructure hidden underground? A standard RICS homebuyer's report does not cover the condition of the drainage system. This is why a pre-purchase CCTV Drainage Survey is absolutely essential.
The Hidden Risks of Underground Drains
Drains are out of sight and out of mind—until they go wrong. When you purchase a property, you inherit its drainage system, along with any existing faults. If a pipe collapses a week after you move in, the financial responsibility falls entirely on you.
Common issues found during a homebuyer drain survey include:
- Tree Root Ingress: Roots naturally seek out moisture and can easily penetrate the joints of older clay pipes, causing severe blockages and structural damage.
- Collapsed or Fractured Pipes: Ground movement, heavy vehicle traffic, or simply old age can cause pipes to crack or collapse entirely.
- Illegal Connections: Sometimes, extensions or conservatories are built over drains illegally, or wastewater is plumbed into surface water drains. You could be fined for this if discovered.
- Rat Infestations: Broken pipes are the number one entry point for rodents entering a property.
How a CCTV Drainage Survey Protects You
A CCTV drainage survey involves passing a high-tech crawler camera through the pipework. This provides a live, high-definition video feed of the inside of the drains, allowing our engineers to spot even the smallest hairline cracks.
If we find a problem, it doesn't necessarily mean you shouldn't buy the house. Instead, our WRC-approved report gives you the power to negotiate. If a survey reveals £3,000 worth of necessary drain repairs, you can ask the seller to either fix the issue before exchange or deduct the cost from the asking price.
Without the survey, that £3,000 bill would have been yours to pay.
Mortgage Lenders and Insurance
Increasingly, mortgage lenders and insurance companies are requesting a CCTV drainage survey before approving a loan or policy, particularly for older properties or homes with a history of subsidence. Having a comprehensive, professional report ready can speed up your conveyancing process significantly.
