Thinking of buying a rural property? Don’t overlook the septic tank — it could cost you thousands if it’s faulty, illegal or neglected.
If a property isn’t connected to mains drainage, it relies on a private sewage system like a septic tank. Without a proper septic tank survey, you could be buying a serious (and smelly) problem.
Why Faulty Septic Tanks Are a Hidden Danger
Septic systems are often out of sight — and out of mind — during a house viewing. But failing to check them can lead to serious financial and legal consequences.
You Could Face Huge Repair Bills
If the tank is leaking, damaged or too small for the property, you might need a full replacement. That can cost anywhere from £5,000 to £20,000 depending on the type of system and ground conditions.
You May Be Breaking the Law
Since 2020, septic tanks in England must not discharge directly into a stream, ditch or surface water. If they do, the homeowner is legally responsible — and could face action from the Environment Agency. Read more on GOV.UK.
Future Buyers Might Walk Away
When you sell the house later, any problems with the septic system will need to be disclosed. Buyers are increasingly aware of the risks and may back out unless a recent survey confirms the system is compliant and working properly.
How to Protect Yourself
The best way to avoid septic tank surprises is with a dedicated inspection before you commit to the purchase.
At Boxall Ward, we specialise in homebuyer septic tank surveys that check for condition, capacity, compliance, and potential risks. You’ll get a clear, jargon-free report so you can move forward with confidence — or renegotiate the price if needed.
