EU Declaration of Conformity

All our septic tank systems meet all strict European Union standards and compliance for safety, health and environmental protection standards.  They're all certified to be compliant and approved.
  • ROHS & REACH Compliant
  • 'Green Tick' Sustainable Certified
  • CE Approved and Certified

Aftercare is important too | We don't 'Fit & Forget' about you. That's not who we are.

All our septic tank systems are designed to be 'Fit and Forget' systems with minimal maintenance and care required.  
| But, we don't forget about you.  Our Aftercare Service is industry leading.  We're available to you for the full duration of your 25 year guarantee.  If you have any issues, need some advice or have any other worries or concerns about your system, just call us and we'll do whatever it takes, or whatever is needed, to resolve any issue you may have.  Of course, you can prolong the useful life of your septic tank system by following the simple 'Use Guidelines' that we provide with every installation.  We'll even send you a useful reminder to have your septic tank emptied at regular intervals, normally every 3 years.  Our automated system will also send you a monthly reminder to top-up your system with Bio-Activator to keep it working efficiently.

Some Aftercare Service Call-Outs may be chargeable if the Use Guidelines have not been followed and the issues are not a system failure
due to product failure or installation issues.  We are always fair and will endeavour to minimise any Aftercare Call-Out costs to you.

Every installation makes a difference.

THANK YOU. Every Septic Tank System we install allows us to make a financial contribution to a regional veterinary surgery to help fund the care, support and welfare of street dogs.

  • This support can take the form of either funding neutering projects, help those less financially able to pay their veterinary bills or any other projects and/or situations where the veterinary surgery needs a little more support.  It all makes a difference, one dog at a time.

A gift from us to you to say Thank You

| All our septic tank systems are supplied with up to 2 years of Bio-Activator and a complimentary bottle of WC Bio Gel to get you started with your new septic tank system.  Additional supplies available to purchase direct from us and can be despatched and delivered to you via Speedy or Ekont.
