Buying a property with a private drainage system?
This specialised survey could save you thousands!
So, you’ve found your dream home—congratulations! But before you dive into picking out new curtains, let’s talk about something a bit less exciting but just as important: private drainage systems. If your new property is relying on one, you could be looking at unexpected repair bills that could knock your budget for six.

Is a private drainage system included in the home buyers report?
In short—no. That Home Buyers Report you're relying on won’t cover the specifics of a private drainage system, whether it's a septic tank, soakaway, or sewage treatment plant. That’s where a specialised House Purchase Drain Survey comes in handy. This comprehensive survey digs deep into the condition of the system, helping you avoid any nasty surprises after the sale goes through.
Who’s responsible for maintaining a private drainage system?
If your new home has a private drainage system, you’ll be the one responsible for ensuring it meets all the necessary standards. Whether it’s a septic tank or a sewage treatment plant, you’ll be classed as the "operator," which means the upkeep, repairs, and ensuring it complies with Environment Agency standards is down to you.
It’s vital to get a full rundown from the current owner before you sign any contracts. If the system doesn’t meet the Environment Agency's 'general binding rules,' necessary upgrades or replacements could be something to negotiate with the seller before the sale goes through.
