Buying or selling a property with off-mains drainage?

A specialist drainage survey can help you understand what’s in place, its condition and whether there are issues to deal with before the transaction gets too far down the line.

The same system. Different questions.

Whether you’re about to take responsibility for an unfamiliar system or preparing your own property for sale, getting specialist advice early can remove uncertainty and help avoid last-minute surprises.

WES staff examining drainage in a garden.

Some of the most important details are below ground

A standard property survey may not inspect a septic tank, sewage treatment plant or the associated drainage in enough detail to establish its condition and compliance.

WES specialises in off-mains drainage. We assess the existing arrangement, look for visible defects or concerns, establish how the system discharges and report on what we find so you can make decisions with better information.

A clearer picture of the system you’re dealing with

What’s installed

The type of system, how it is arranged and how it serves the property.

Condition

Visible signs of damage, deterioration or other concerns with the existing arrangement.

Compliance

Whether the system and discharge arrangement appear to meet the relevant current requirements.

What happens next

Practical guidance where further investigation, repair or upgrading may be needed.

Earlier is easier

The best time to understand an off-mains drainage system is before it becomes a last-minute problem.

Buyers have time to understand what they may be taking on. Sellers have time to deal with questions before they start holding up the transaction.

You’re not left with a report and no clear next step

If the survey identifies an issue, WES can explain the options and, where appropriate, provide the design, specification or remedial works needed to put it right.

That might mean a repair, further investigation or replacing an outdated or non-compliant system.
