Septic Tank Installation in Crawley and the South East

We are specialist septic tank installers based in Crawley who serve the wider South East of England for domestic, commercial and industrial clients. From the initial site visit to the final backfilling, you’ll be in safe hands here at Peachy Services.

Our septic tank installation process

1) Site Survey and Planning

When installing septic tanks, we start by assessing your property’s needs such as the soil conditions and the local regulations. Our team will design and install a septic tank system that is tailored to your requirements; choosing the right brand and product for your needs. If you are replacing septic tank systems that discharge to surface water, we’ll help you explore compliant alternatives under new UK regulations.

2) Design and System Selection

We design your system to match property use, capacity needs (e.g. tank size from 2,000 to 20,000 litres) and environmental constraints. That includes options for a replacement septic tank or full septic systems installation.

3) Installation of Septic Tanks

When it comes to the installation itself, we provide an end-to-end service to ensure a smooth installation. Our team handles excavation, delivery and placement of the tank, connection to your plumbing and soakaway, electrical work (for treatment plants), then backfill and restore the ground. 

4) Final Testing

We test flow rates, carry out discharge testing where needed and hand over detailed compliance paperwork.

Replacement Septic Tank or Upgrading to Treatment Plant

When replacing septic tanks you’ll avoid fines and pollution risk. Under the 2020 rules governing septic tank replacement, systems discharging into ditches, streams or ponds must now be swapped for sewage treatment plant installations.

We advise on whether you should install a replacement septic tank or upgrade to a modern sewage treatment plant for long‑term compliance and reduced maintenance.

Ongoing Care after Installing a Septic Tank System

Installing a septic tank doesn’t end the service. In order to maintain optimal function, you will need annual servicing and desludging every 1-3 years depending on household size.

We offer tailored maintenance plans to keep your system running reliably. We also repair or replace worn components quickly, with minimal disruption.

Commercial Septic Tank Installation for Businesses and Industrial Sites

If your business operates off the mains, you need a system that handles heavy use, complies with environmental rules and works without disruption. We install and replace commercial septic tanks for all types of organisations across the South East – from charities and schools to pubs, campsites and office parks.

Why businesses choose Peachy Services:

  • We design high-capacity septic systems built for commercial use
  • We understand Building Regs and Environment Agency discharge rules
  • We work around your hours to avoid disruption
  • We handle full paperwork for planning, permits and compliance
  • We offer maintenance contracts and emergency support after install

Larger properties or commercial buildings often need multi-chambered or higher-volume septic systems. Our team installs everything from 5,000-litre to 50,000-litre tanks, using manufacturers like Marsh, Klargester and Tricel.

Need to serve 20+ people per day?

We’ll carry out a full percolation test and population load assessment, then recommend the right tank size and soakaway system. If a gravity-fed system isn’t suitable, we’ll fit a pumped setup.

From the initial survey to the last inspection, we’ll make sure your commercial septic tank system works reliably, handles the right volume, and stays within the law.
