When a property isn’t connected to the main sewer system, things can get complicated — fast. That’s where Off Mains Solution come in. They’re the go-to experts for all things off-mains drainage, from septic tanks and soakaways to sewage treatment plants and legal compliance.

Selling your property?

If your property uses off-mains drainage (cesspit, septic tank, or sewage treatment plant), proactive preparation is key to a smooth sale. Start by gathering all maintenance and emptying records. But the most crucial step? Commissioning a pre-sale specialist drainage survey from a recognised professional like Off Mains Solution. This expert inspection confirms your system’s condition, functionality, and, most importantly, its compliance with current Environment Agency General Binding Rules.

Providing a recent, independent report shows transparency and gives you the chance to address any issues — like non-compliance — before they become a hurdle during the sale. It builds buyer confidence, avoids last-minute renegotiations, and significantly increases your chances of a faster, smoother sale.

Buying a property?

If the property you’re considering uses off-mains drainage, that means it isn’t connected to the public sewer network — and you will be responsible for its maintenance and legal compliance. Getting it checked properly is essential to avoid costly surprises later.

Your Essential Due Diligence:

  • Request seller documentation – system type, location, maintenance history, and emptying receipts.
  • Commission a specialist drainage survey – a general property surveyor is not qualified for this in-depth check. Use a recognised expert like Off Mains Solution.
