The Environment Agency introduced a voluntary remediation advice service in June 2026 for a specific type of contaminated-land problem: sites where land contamination has impacted controlled waters and the owner or developer wants site-specific regulatory and technical input outside the normal planning or permitting routes.
It is a useful development, but it is not a general pre-application advice service and it is not a way to obtain an Environment Agency “sign-off” for any contaminated site. Understanding that boundary is important before deciding whether the service is worth using.
Who can use the service?
The service is restricted to sites where land contamination has impacted controlled waters. Controlled waters include groundwater as well as inland freshwaters, territorial waters and coastal waters.
The Environment Agency says the site must sit outside a spatial planning application or discharge-of-condition consultation. It must also not already be regulated under the Environmental Permitting Regulations and must not be subject to a Part 2A determination, an environmental-damage remediation notice or an anti-pollution works notice.
In other words, this is aimed at voluntary remediation situations where there is a real water-environment issue but no existing regulatory route already doing the job.
What can the Environment Agency review?
The service can provide regulatory and technical review of work prepared by competent environmental consultants in line with the Land Contamination Risk Management (LCRM) framework. The published list is broad and covers the main stages of a contaminated-land project, including:
- preliminary risk assessments and conceptual site models;
- site-investigation proposals and results;
- generic and detailed quantitative risk assessments;
- remediation options appraisals and remediation strategies;
- remediation method statements;
- monitoring proposals; and
- verification reports.
The Environment Agency’s review focuses on whether the site presents an acceptable or unacceptable risk of pollution to the water environment.
Where could this be useful?
There are situations where a landowner is trying to resolve legacy contamination without an active planning condition driving the programme. Examples might include a historical release affecting groundwater, voluntary clean-up before a transaction, or a site where remediation is being considered to manage an ongoing controlled-waters risk.
In those circumstances, regulator input can help test whether the investigation, risk assessment and remediation strategy are addressing the issues that matter to the water environment. That can be valuable before significant money is committed to a remediation approach.
The key is that the technical submission still has to do the heavy lifting. The Environment Agency expects the applicant to be a competent person and recommends following LCRM. A weak conceptual site model or poorly designed investigation does not become robust simply because it has been sent for regulatory review.
What the service does not provide
The limitations are just as important as the services offered. The Environment Agency states that voluntary remediation advice cannot confirm that a permit is unnecessary, confirm compliance with general binding rules for discharges to ground or surface water, or guarantee that documents will be acceptable for a future planning or environmental-permit application.
It also does not cover work associated with waste definition, radioactive substances or hydraulic fracturing.
The outcome should therefore be treated as technical and regulatory advice for the current contaminated-land and controlled-waters issue, not as a blanket approval that replaces other consents.
How the charging process works
The initial review is charged on the basis of five hours of Environment Agency time to examine the submission and identify the technical and legal input needed for the full assessment. If more work is required, the Agency provides an estimate and invoices for completed work.
Availability can vary by area because the service depends on local resources and priorities, so the relevant groundwater and contaminated-land team should be contacted before relying on the service within a programme.
Preparing a submission that is worth reviewing
If we were preparing a project for voluntary remediation advice, we would want the evidence organised before approaching the regulator. That normally means a clear preliminary risk assessment, a defensible conceptual site model, appropriately scoped intrusive data where required, and a clear explanation of the controlled-waters pollutant linkage.
Where further investigation is necessary, a Phase 2 Ground Investigation should be designed around the actual source, pathway and receptor questions. If remediation is being proposed, the strategy should explain not only what will be done but how success will be demonstrated through monitoring and verification.
EnviroSolution provides contaminated-land consultancy from preliminary risk assessment through investigation, remediation and validation. Where controlled waters are involved, we can help determine whether voluntary Environment Agency advice is relevant and prepare the technical evidence needed to make that engagement useful.
