Compliance
Find out whether your septic tank or sewage treatment plant meets the UK General Binding Rules — before it costs you far more than it should.
If your property isn't connected to the mains sewer, the way your wastewater drains away is governed by the Environment Agency's General Binding Rules. These rules apply right across Lancashire — whether you're in a rural farmhouse near the Forest of Bowland, a converted barn outside Clitheroe, or a village property on the edge of the Ribble Valley. They cover any system that discharges to ground or to a watercourse, including septic tanks and sewage treatment plants. As the property owner, the legal responsibility for compliance sits with you.
A Tank Compliance Survey from Lancashire Septics Ltd gives you a clear, independent picture of whether your drainage system is working within the law and treating effluent to the standard the rules require. It's not just a tick-box exercise — it's genuine peace of mind, and it can save you from enforcement notices, significant fines, or a costly last-minute replacement that derails a property sale.
One thing worth knowing: a septic tank can pass the General Binding Rules. Not every system needs upgrading to a sewage treatment plant, and we'll never recommend work that isn't genuinely necessary. Our job is to give you honest information, not to sell you a new installation. If your tank and its discharge point are correctly set up and maintained, we'll tell you so in plain English.
The survey itself begins with one of our vacuum tankers arriving to empty and prepare the tank for internal inspection. Once the tank is clear, a qualified surveyor carries out a thorough check of the tank condition, the drainage layout, and the discharge arrangements. We map the full drainage network as part of every survey — a clear, easy-to-read plan that stays useful long after the visit is done.
Within roughly five working days of the site visit, you'll receive a written report covering everything we found. Where issues exist, the report explains each one, sets out the options for putting things right, and includes associated costs so you know exactly where you stand. That report is equally useful whether you need it for your own records, a mortgage provider's retention requirement, or negotiations around a property purchase or sale.
If you're buying a home in Lancashire with its own private drainage, arranging a compliance survey before you exchange is one of the most straightforward ways to protect yourself. Inherited drainage problems can be expensive to fix, and they're rarely factored into an initial offer. Get the facts first — then negotiate from a position of knowledge.

What's included
Pre-purchase compliance survey
Arranged before exchange of contracts, this survey tells buyers exactly what condition a private drainage system is in and whether it meets current legal requirements — essential protection when purchasing rural or off-mains property anywhere in Lancashire.
Existing homeowner compliance check
If you already own a property with a septic tank or sewage treatment plant and want to confirm you're meeting your obligations under the General Binding Rules, this survey gives you a definitive answer along with practical guidance on any remedial steps needed.
Mortgage retention survey
Where a lender has flagged private drainage and held back funds pending an inspection, our compliance report is produced in a format that clearly documents findings and proposed works to help satisfy the retention requirement.
Frequently asked questions
- What are the General Binding Rules and do they apply to my property?
- The General Binding Rules are the Environment Agency's standard conditions for small sewage discharges from domestic properties that aren't connected to the public sewer. If your home has a septic tank or sewage treatment plant that discharges to the ground or a nearby watercourse — which is very common across rural Lancashire — then yes, the rules apply to you. Compliance is the legal responsibility of the property owner, not a landlord, previous owner, or installer.
- My building surveyor has flagged the private drainage — what happens next?
- Building surveyors routinely recommend a specialist drainage inspection when a property has its own off-mains system, particularly if the system is older or its condition isn't known. A Tank Compliance Survey goes deeper than a standard homebuyer's report, inspecting the tank internally and assessing the full discharge arrangement against current regulations. We work alongside building surveyors regularly and can produce a report in a format that's easy to cross-reference with their findings.
- Who pays for the compliance survey — the buyer or the seller?
- There's no fixed rule on this, and it's often something both parties negotiate as part of a sale. In practice, buyers most frequently commission the survey because they're the ones who need to know what they're taking on. Where tank emptying is required as part of the inspection process, it's fairly common for the cost of that element to be shared between buyer and seller — but this is entirely a matter for the parties involved.
- How does pricing work for a Tank Compliance Survey?
- Because every property and drainage system is different, we provide a tailored quote rather than a one-size-fits-all price. Factors that affect the cost include the size and accessibility of the tank, the complexity of the drainage network, and whether tank emptying is required beforehand. Get in touch with a few details about your property and we'll come back to you with a clear, itemised figure — no hidden extras.
- Does a septic tank always need to be replaced with a sewage treatment plant to pass?
- Not necessarily — this is one of the most common misunderstandings around the General Binding Rules. A septic tank can meet the rules provided it discharges to an approved drainage field (not directly to a watercourse) and the drainage field itself is functioning properly. We'll assess your specific setup honestly and only recommend an upgrade if the evidence genuinely supports it.
- Can repairs or upgrades be carried out before a property sale completes?
- In many cases, yes. Straightforward remedial work can often be completed relatively quickly. Where the required work is more extensive and timing is tight, a mortgage retention arrangement — typically allowing several months for works to be completed after completion — is a common and well-established route. Our compliance report includes the information mortgage lenders and solicitors usually need to set up that kind of arrangement.
