Selling a House with a Septic Tank: New Regulations

Selling a house with a septic tankOn the 1st of January 2020, the regulations for septic tanks in the UK changed and new regulations were put in place to make systems more environmentally friendly. The new general binding rules state that septic tanks cannot discharge into surface water, significantly cutting pollution.

If you have not had your septic tank replaced and it is still discharging into surface water, you will face a significant fine. Call the team at Coastal Drains today! Our team can come around and replace your septic tank with a system that’s inline with the new regulations.

Provide All Septic Tank Information to the Buyer in Writing

If you are the seller of a property with a septic tank, you have a legal obligation to inform the buyer in writing about your septic tank. You need to clearly state where the septic tank is situated and what kind of maintenance is required to keep the system running effectively. It is also your responsibility to inform the buyer of any problems with the septic tank, but be aware that you will be expected to carry out any relevant repairs before the sale is completed.

When providing information about your septic tank system to the buyer, you should include the following information:

  • Details of any changes made to the system.
  • A full description of the drainage system.
  • Details and costs of maintenance, in addition to any maintenance manuals you have.
  • The location of the system and the discharge point.
  • Records of any maintenance that has been carried out on the system.

Be Clear About the Sewage System on Your Property

Amongst all the business of selling your house, it is easy to forget that the buyer may not know what type of sewage system you actually have. There are three main types of sewage systems and they all work slightly differently, so it is important you are clear with the buyer about what type you have so that they know what they’re dealing with.

Cesspits or Cesspools: these are storage systems that collect waste water from your property and store it for emptying. It is common for cesspits and cesspools to be found on older properties.

Sewage Treatment Plants: these systems clean the waste that is drained from your property, ensuring that it can be safely released.

Septic Tanks: these are the most popular private drainage solutions – particularly for rural properties – as they collect and store untreated effluent that is then collected in full and transported to a treatment plant for treating.

Selling a House with a Septic Tank: Be Honest

If you want the sale of your property to go as smoothly as possible, it is important to be upfront with potential buyers about the condition of your septic tank. Whether your septic tank is in poor condition or it has been regularly and professionally maintained, you need to be honest. If you provide information to the buyer, you could be charged, so it is important to be as accurate as possible.

What Happens if the Septic Tank Needs Repairing?

If you are trying to sell your house and you realise that your septic tank needs repairing, it is best to fix the problem before finalising the sale of your property. Although this is not a legal requirement, we know from experience that properties with functioning private drainage systems are far more appealing to potential buyers than those without.

So, if you know that your septic tank just isn’t up to standard, is damaged, or is not functioning properly, call our team today and we will carry out the relevant repairs. If the repairs are extensive and you don’t have the money, it may be more cost-effective to negotiate with the buyer on reducing the price of the property to cover any repairs. It may be that some buyers find this option appealing as it means they will have control over the work carried out, ensuring all repairs are completed to a satisfactory standard.
