Your septic installation done right — the first time
Installing a new system usually means dealing with several companies, including the manufacturer who made it and the contractor who puts it in the ground.
We're one of the only companies in the UK that does both.
As the exclusive installer of Ecoflo products, we know exactly how to put your system in place and how to make sure it's working properly.
We leave your site tidy at the end of each day, and keep you informed throughout the works. If your property has an existing system, we'll decommission it as part of our service, at no extra cost.
If anything needs attention after installation, you never need to ask who is responsible. It's us.
Already have a design from another provider?
You can still choose our products and installation team. Ask and we'll create a new septic design for you — at no cost.
How we install your off-mains drainage system
In most cases, installations take a week from site preparation to final handoff.
Here's what to expect:
- Site walk and preparation
Before any digging begins, our team walks the site, confirms the plan, and carries out a risk assessment. This makes sure the installation runs smoothly and safely. - Excavation
We excavate the ground to accommodate your system and drainage field, taking care to avoid utility lines and keep disruption to a minimum. - System installation
We position and secure your system at the correct depth so that wastewater flows properly from your home through to the drainage field. - Backfill and compaction
Once everything is in place, we fill the excavated area back in and compact it carefully to protect your system and restore the ground above. - Final tidy
We do a final tidy and, if you'd like, seed the exposed soil with grass. Most gardens return to a normal appearance within 6 to 8 weeks, depending on the season. - Commissioning (for sewage treatment plants)
If your system includes a sewage treatment plant, we test all mechanical and electrical components to confirm everything is working as it should. - Handover
Before we leave, we walk you through your new system — how it works, what to keep an eye on, and when to book your first service.
Honest pricing, no surprises
Our installations normally fall between £6,000 and £11,000. This covers all equipment, excavation, groundworks, and labour.
Installation is the largest single cost in a new septic project. Looking at the full picture — site assessments, soil testing, regulatory fees, the system itself, and installation — most projects come in between £8,000 and £15,000.
Beyond the numbers, here's the value we offer:
- a team that understands this is your home, not just a job site
- decommissioning your existing system, if there is one, at no extra charge
- a plain-language handover before we leave, so you know exactly how your system works
