Accredited analysis for water-industry soil-reuse compliance — keeping your installation programme stable and adoption-ready.
You may need UKWIR testing if you’re installing new water mains or service pipes on a brownfield site, a redevelopment plot, or land with any potential contamination history.
Water companies and Self-Lay Providers (SLPs) require UKWIR-compliant evidence to confirm the ground will not degrade or permeate water pipes.
This early clarity protects you from last-minute delays and unplanned redesign.
UKWIR (UK Water Industry Research) provides the official guidance used by water companies to decide which pipe materials, barrier systems, or protective coatings are suitable for installation on contaminated or potentially contaminated sites.
A UKWIR test identifies contaminants that may affect pipe integrity — including chemicals capable of permeating plastics, attacking metal pipes, or compromising long-term safety.
Our testing is aligned with the UKWIR Guidance for the Selection of Water Supply Pipes to be Used in Brownfield Sites (Ref 10/WM/03/21).

Administrative Indicators
Early instruction avoids redesign cost and programme friction.
| Service | Purpose | Outcome |
|---|---|---|
| Site Review & Desk Study | Assess historical land use and contamination risk. | Confirms sampling locations and test scope. |
| Soil Sampling & Accredited Laboratory Testing | Targeted sample collection and full UKWIR analysis. | Independent, chain-of-custody laboratory data. |
| Typical Analyses Include | ||
| • Petroleum hydrocarbons (TPH, BTEX, MTBE) | Identify organic contamination affecting pipe permeation. | Defines material suitability. |
| • VOCs / SVOCs | Assess volatile and semi-volatile contaminants. | Ensures safe selection of pipe barriers. |
| • Phenols & chlorinated compounds | Identify legacy industrial contaminants. | Supports correct coating specification. |
| • Heavy metals | Assess corrosion potential. | Protects long-term pipe integrity. |
| • Soil pH, electrical conductivity, redox potential | Evaluate chemical environment around pipes. | Confirms compatibility with pipe materials. |
| UKWIR-Compliant Reporting | Submission-ready documentation for water company or SLP. | Clear, traceable, UKAS-accredited results. |
| Pipe Material Selection Advice | Determine correct pipe type, barrier system or protective coating. | Adoption-ready specification with no ambiguity. |
That’s how evidence stays proportionate, pipe selection stays compliant, and your installation programme keeps moving.

Not always — but you do if the water company, SLP or local authority requires contamination evidence before approving pipe materials. If the ground has any industrial, commercial or fuel-storage history, testing is almost always mandatory.
Testing includes petroleum hydrocarbons (TPH, BTEX, MTBE), VOCs/SVOCs, phenols, chlorinated compounds, heavy metals, and supporting soil parameters such as pH, electrical conductivity and redox potential.
No. A Phase 1 or 2 assesses environmental risk; UKWIR testing specifically determines pipe material compatibility and adoption compliance. Many brownfield projects require both.
It depends on the size of the pipe route, contamination history, and variability of Made Ground. We provide sampling guidance or attend site directly.
Yes — most SLPs must submit UKWIR-compliant evidence to water companies before mains adoption.
Yes. The laboratory data determines whether you need:
This prevents costly replacement later.
Typically within 10 working days of sample receipt, with fast-track options available.
Yes — or we can provide detailed sampling instructions if your contractor prefers to collect.
Yes — results are UKAS-accredited and aligned with UKWIR Ref 10/WM/03/21.
Indirectly. Planning conditions relating to utilities or contamination often require evidence before connection or adoption.
Yes — water companies may refuse connection or adoption without compliant laboratory results.
We conduct sampling and reporting across England and Wales.
