Replacement or new installation?

Not sure which applies? Here's the difference — and the right next step for each.

Replacement

Replacing a failing system

You already have a septic tank, cesspit or treatment plant that's failing, non-compliant, or nearing end-of-life. A home survey confirms what needs to change and what the replacement should look like.

  • Tank is leaking, overflowing or backing up
  • System discharges to surface water (no longer permitted)
  • Property is being sold and needs a compliance check
  • Household or commercial usage has outgrown the tank

New Installation

Installing a brand-new system

You're building, extending, or moving to a property without mains drainage. We help you select and size the right system for your location, occupancy and site conditions.

  • New-build residential or commercial property
  • Extension adding bedrooms or bathrooms
  • Converted barn, annexe or outbuilding
  • Site with no existing foul drainage

Survey-led approach

Why a home survey saves you money

Septic tank projects can go wrong quickly when the system is sized, sited or specified incorrectly. A site survey catches issues before they become expensive — and ensures the installation you book is right for your property from day one.

  • Confirms soil type, porosity and drainage field suitability
  • Checks access for excavation and equipment
  • Identifies compliance or permit requirements
  • Specifies correct tank size for expected usage

Common questions

Frequently asked questions

Everything you need to know before booking a survey or installation.

Costs vary significantly based on property size, soil conditions and the type of system required. Typical budgetary ranges in the UK sit between £3,500 and £7,500 fitted for a standard domestic septic tank, and £6,000 to £12,000+ for a sewage treatment plant. Commercial systems are quoted based on peak usage. A home survey provides an accurate price for your specific site.

In most cases, yes. A survey confirms soil conditions, drainage field suitability, access for excavation and whether a standard septic tank or a sewage treatment plant is the right choice. Without a survey, you risk specifying the wrong system — or discovering compliance issues after installation.

Since January 2020, septic tanks discharging directly to surface water (streams, ditches, rivers) have been non-compliant. Systems must either discharge to a drainage field via a soakaway, or be replaced with a sewage treatment plant. If you're selling a property, compliance is typically checked at the conveyancing stage. Our surveys always include a compliance review.

A straightforward domestic replacement typically takes 2–5 days on site once groundwork begins, depending on soil conditions and drainage field requirements. Commercial installations take longer and are scheduled to minimise operational disruption. Your survey will confirm an accurate timeline.

Yes. Our specialist network includes installers experienced with pubs, restaurants, B&Bs, holiday parks, campsites, farms and rural estates. Commercial systems are sized for peak occupancy and compliance requirements, and we can typically scope, specify and schedule work with minimal downtime.

Enquiring and being matched with a specialist is free. The home survey itself may be chargeable depending on distance and property type — your matched specialist will confirm this before any visit is booked. You're never obligated to proceed after the survey.
