Rather than getting fitter or drinking less, a new year could mark a commitment to compliance for UK homeowners with septic tanks.
The latest General Binding Rules now fully reflect updates made by the Environment Agency in October 2023. And to preserve the local environment, protect your property value and avoid any legal or enforcement action, here’s what you need
What do the General Binding Rules cover?
First created over a decade ago and updated several times since, these are the legal minimum standards for ‘small sewage discharges’. The rules apply to septic tanks and small sewage treatment plants in England and Wales. Exact requirements differ depending on your type of property, its location and which sort of system is in situ. But as a minimum, all homes with septic tanks will need to comply with the following:
- Only discharge two cubic metres or less in one day – This waste must be domestic only, not commercial – to work out how much you currently discharge daily, use this helpful calculator
- Proper maintenance – Your septic tank should be emptied at least once a year and any waste removed by a registered waste carrier
- Don’t pollute surface or ground water – Check for signs your sewage isn’t draining properly, such as smells, overflowing sludge or pooling water
- Ensure discharge isn’t in a Groundwater Protection Zone (SPZ1) – An example of an SPZ1 might be the area around a commercial water supply used for drinking water or food production
Non-compliance with these rules and more could leave you liable to fines and even affect the value of your property. North of the border, separate rules laid out by the Scottish Environment Protection Agency (SEPA) are applicable.
How do I ensure my home is up-to-date?
The simplest way to achieve peace-of-mind over your septic tank compliance is by engaging a professional. Not only will you find out if your home meets the standards, you’ll also receive practical guidance on what steps to take if not.
An initial drainage and septic tank survey is the most straightforward way to ascertain the condition of your system. This is also a surefire method to determine whether or not your septic tank requires any repair or replacement work.
And if you’re still only considering buying a property with a septic tank, a home buyer’s drainage survey is advisable before committing to anything more costly.
Make 2026 the year of a healthy septic tank
While the General Binding Rules don’t always change annually, it’s important to ensure your septic tank compliance is up-to-date. This is especially true if you’re looking to move house this year – as failing to meet the required standards could prove expensive.
