Are We Environmental Consultants? Or Are We Report Authors?

Introduction
In 2008, The Killers released their hit song “Human”. Earlier this week, Spotify delivered it to me during a shuffle session.
Firstly, it reminded me that even in 2025, it’s still an absolute banger.
Secondly, the iconic line “Are we human? Or are we dancer?” got me thinking. I ended up deep in a Reddit rabbit hole, searching for what Brandon Flowers might have meant.
Some say it was inspired by a quote from Hunter S. Thompson: “We (America) are raising a generation of dancers.” Others suggest it’s about rejecting societal control and not dancing to the puppet master’s demands.
I'm still not sure. But it got me thinking about a question that matters to us at Clear Environmental:
Are we consultants? Or are we just report authors?
The Regulatory Problem
In the UK, environmental consultants must understand and apply a wide range of guidance and legislation: the Environmental Protection Act 1990, Land Contamination Risk Management (LCRM), CIRIA, CL:AIRE, NHBC, SOBRA, British Standards… the list goes on.
But guidance isn’t one size fits all. It’s not black and white. It’s a best-practice framework to interpret and assess environmental risk.
And because no guidance can account for every eventuality, especially in complex contaminated land scenarios, this is where the role of the consultant comes into play.
We can’t be driven solely by a number or a value in a document. The environment is a complex, interconnected system. Reducing it to a single gas threshold or soil concentration does a disservice not just to the environment but to the skills and judgement we bring as professionals.
Environmental Due Diligence - Why Guidance Alone Doesn’t Work in Commercial Property Deals
Much of UK contaminated land guidance is tailored to redevelopment, assessing sites for “unacceptable risk” to human health or the environment.
LCRM, for example, sets out a clear four-step process
This process makes sense when a site is changing use. But for commercial property transactions, where no change of use is proposed, this doesn’t always align with commercial realities.
Deals often hang on the ability to receive quick, informed advice. A six-week site investigation programme won’t serve an investor looking to complete in two weeks.
That’s where consultancy steps in. If we identify elevated risk, we must consider all options, including Environmental Insurance, which can transfer residual liability associated with historical contamination.
These products can be arranged in days and transferred to future purchasers. They enable the deal to proceed while managing risk, something guidance alone doesn’t always account for.
If we were report authors alone, we might stop at recommending a site investigation. But that could stall or kill the deal. As consultants, we provide commercial solutions.
Site Condition Reports for Lease Surrender - How Consultants Help Landlords and Tenants Manage Environmental Risk
Clear Environmental has recently been involved in environmental dilapidation claims. These often arise at lease surrender, where contamination or environmental liabilities become a financial or legal issue.
Sometimes, it’s clear that tenant activities have caused contamination, for example, a significant fuel spill.
But more often, it’s unclear. Industrial sites may have decades of historical use. Without a baseline report from the start of tenancy, how can you prove whether a spill happened in 2015 or 1985?
To protect both landlords and tenants, two things should be considered:
1.Clear Lease Obligation
- Precisely define the leased premises, including the ground beneath the site, and specify the tenant's responsibilities concerning these areas.
- Carefully draft repairing covenants to clarify the extent of the tenant's obligations, distinguishing between maintaining the property's current condition and improving it.
- Include responsibilities to comply with environmental legislation and to report any known contamination during the term of the lease.
2.Baseline Site Condition Reports:
- Establish environmental conditions at lease commencement.
- Provide a reference point to evaluate whether conditions have materially deteriorated at lease end.
These aren’t standardised in guidance unless required by a permitted activity. But they should be considered for any lease involving potentially contaminative activity as they offer clarity, protect asset value, and minimise legal disputes.
Land Remediation Relief - Spotting Opportunities Others Might Miss
Another area where consultancy shines is identifying financial opportunities.
Land Remediation Relief (LRR) is a government incentive that allows companies to claim enhanced tax relief on qualifying remediation costs.
It is often overlooked and many landowners simply are not aware of LRR.
A consultant with awareness of LRR can:
- Identify eligible works early
- Ensure appropriate records and reporting are maintained
- Liaise with accountants to optimise the claim
This kind of insight is rarely included in a standard report. But it can deliver significant savings.
Being a consultant means seeing beyond the report we are writing and considering the wider commercial aims of the project. We need to ensure we are adding value to the schemes we are involved with, especially by means our clients may not even be aware of.
Conclusion
Are we consultants, or are we just report authors?
At Clear Environmental, we believe our value lies in interpretation, not just documentation. Guidance exists for a reason, but it doesn’t always provide the full picture. Our role is to understand the science, apply the context, and deliver pragmatic, commercially aware solutions.
Being a consultant means going beyond the guidance to ask: “So what?”. What do you need to make an informed decision? Crucially, how can we help you get there?
Don’t just write reports. Consult.
When a Phase 1 Desk Study identifies potential environmental risks, the next step is a Phase 2 Site Investigation, also called an intrusive investigation. This critical stage gathers real-world data to confirm or rule out contamination, protecting your project from unforeseen costs, planning delays, or environmental liabilities.
In this guide, we break down:
- How Phase 2 builds on Phase 1.
- The different investigation techniques (and when to use each).
- Typical timescales.
- How laboratory testing refines the site’s risk profile.
- What to expect at the end of a Phase 2 investigation.
How Phase 2 Builds on Phase 1
While a Phase 1 is based on desk research and a site walkover, a Phase 2 collects physical evidence through soil, groundwater, and ground gas sampling.
In short:
Phase 1 = Identify Potential Risks.
Phase 2 = Confirm or Dismiss Risks with Hard Data.
The findings from Phase 2 enable:
- Quantitative Risk Assessments (QRA) based on actual contamination levels.
- Decisions about whether remediation is necessary.
- Planning condition discharge if no unacceptable risks are found.
Phase 2 Site Investigation Methods
Different methods are used depending on the site, the anticipated risks, and the required depth of investigation:
- Best For: Shallow contamination, made ground assessment, visual soil profiling, locating foundations.
- Typical Depths: Up to 4 metres.
- Equipment: Mechanical excavator or hand-dug.
- Best For: Shallow contamination, installation of ground gas and groundwater wells, restricted access sites, cost-effective sampling.
- Typical Depths: Generally 5–6 metres, but can extend up to 10 metres depending on ground conditions.
- Equipment: Window sampling rig (tracked or towed).
- Best For: Deeper soils, groundwater sampling, ground gas monitoring, and collecting geotechnical data.
- Typical Depths: Up to 30 metres or more.
- Equipment: Cable percussion drilling rig.
- Best For: Hard ground, bedrock investigations, and installation of deep groundwater wells.
- Typical Depths: Up to 100 metres or more.
- Equipment: Rotary drilling rig (open hole, cored, or augered).
Tip: On smaller development sites, a combination of trial pits and window sampling often provides excellent coverage at a cost-effective price.
Types of Laboratory Testing During Phase 2
After sampling, the materials collected are sent for laboratory analysis to determine contamination levels:
- Soil Testing:
- Heavy metals (e.g., lead, arsenic)
- Hydrocarbons (TPH, PAHs)
- Asbestos in soil
- Emerging contaminants (e.g., PFAS)
- Groundwater Testing:
- Soluble contaminants (e.g., hydrocarbons, BTEX, solvents)
- Metals in solution
- PFAS detection
- Ground Gas Monitoring:
- Methane, carbon dioxide, oxygen concentrations
- Flow rates (for CS classification)
The results are then compared against appropriate assessment criteria to determine whether remediation is needed.
What Happens After Phase 2 Sampling?
1. Data Analysis and Quantitative Risk Assessment (QRA):
Risk to human health, controlled waters, or property assessed.
2. Conceptual Site Model Update:
Confirmed pollutant linkages mapped and risk-ranked.
3. Decision Point:
No significant risks: Reporting and planning condition discharge.
Significant risks: Recommend remediation (Phase 3).

FAQs About Phase 2 Site Investigations
What happens if contamination is found in a Phase 2?
If contaminants exceed safe levels, a Remediation Strategy (Phase 3) will be needed to outline how risks will be managed.
Can a Site Investigations rule out the need for remediation?
Yes — many sites require no further action after a properly scoped Phase 2 investigation.
Is ground gas monitoring always required during a Phase 2?
Not always. It depends on the site's history, geology, and desk study findings.
Why a Clear Phase 2 Strategy Matters
A well-designed Phase 2 Site Investigation provides confidence, clarity, and control.
It ensures you're fully informed about site risks, avoids unnecessary remediation, and moves your project efficiently through planning.
At Clear Environmental, we tailor Phase 2 investigations to your site. No over-scoping, no hidden costs, just clear advice.
If your Phase 2 results raise concerns, understanding how to move forward with proportional, commercially realistic remediation is crucial.

What is a Phase 1 Desk Study (Preliminary Risk Assessment)?
A Phase 1 Desk Study (Preliminary Risk Assessment) is an initial environmental assessment that researches a site’s history and conditions to identify potential contamination risks.
Whether you're planning to develop land, submit a planning application, or purchase a brownfield site, understanding environmental risks early is essential.
A Phase 1 Desk Study (also called a Preliminary Risk Assessment) is the first critical step in managing those risks efficiently, helping avoid costly surprises later in your project.
This guide explains exactly what a Phase 1 involves, why it’s required, and what you can expect from the process.
What is a Phase 1 Desk Study?
A Phase 1 Desk Study is a preliminary environmental assessment that evaluates the potential for land contamination based on historical and current land uses.
It is called a “desk study” because it mainly relies on reviewing existing records and data sources, alongside a site visit.
It does not involve any intrusive ground investigation, that's reserved for Phase 2 if risks are identified.
In simple terms:
A Phase 1 identifies if there’s a potential problem — before you commit to site purchase, design, or construction.
Why is a Phase 1 Desk Study Needed?
A Phase 1 is often required to:
- Support planning applications (especially brownfield or previously developed sites).
- Satisfy lender due diligence for property transactions.
- Manage liability and avoid unexpected abnormal costs.
- Confirm if further investigations (Phase 2) are needed.
Without a Phase 1, local authorities, insurers, and funders may refuse to progress development or financing.
Key Components of a Phase 1 Desk Study
A thorough Phase 1 typically includes:
What Does a Phase 1 Report Contain?
A typical Phase 1 Desk Study Report will include:
- Executive Summary (key findings and recommendations).
- Site location and description.
- Historical land use review (maps and aerial photography).
- Environmental setting (geology, hydrology, groundwater).
- Regulatory database review (permits, enforcement notices, pollution incidents).
- Walkover survey findings (including annotated site photos).
- Preliminary Conceptual Site Model (CSM).
- Risk assessment and clear conclusions.
- Next steps, if further investigation is needed.
At Clear Environmental, our Phase 1 reports are concise, commercially-focused, and designed to satisfy planning authorities and lenders without unnecessary complexity.
How Long Does a Phase 1 Desk Study Take?
Most Phase 1 assessments can be completed within 10 Days.
We also offer fast-track services if you’re working to tight planning or transaction deadlines.
Phase 1 Desk Study vs. Environmental Search: What's the Difference?
Key point: An Environmental Search is not a substitute for a Phase 1 — it’s simply a basic desktop screening.
Why Clear Environmental for Your Phase 1?
A Phase 1 Desk Study isn’t just a box-ticking exercise, it’s your first opportunity to manage risks, reduce abnormal development costs, and protect your investment.
At Clear Environmental, we combine technical expertise with commercial insight to deliver Phase 1 Reports that meet planning, legal, and financial requirements quickly and clearly.

FAQs About Phase 1 Environmental Desk Studies
When should I commission a Phase 1 Environmental Report?
Ideally before site acquisition or at the earliest planning stage, so risks and costs are identified early.
Will a Phase 1 Desk Study always recommend a Phase 2 Site Investigation?
No — many sites with clean histories and no risk linkages can be signed off at Phase 1.
Who needs a Phase 1 Environmental Desk Study?
Developers, property investors, planners, architects, solicitors, and lenders commonly require Phase 1 studies.
Will the council accept my Phase 1 report for planning?
Yes — provided it follows UK guidance (such as EA Land Contamination Risk Management (LCRM)) and is prepared by qualified specialists.
What happens if my Phase 1 shows contamination risks?
We’ll outline the recommended Phase 2 site investigation scope and cost early, so you remain in control.
FAQs About Contaminated Land Assessments
What is a contaminated land assessment?
A contaminated land assessment identifies whether land poses environmental or health risks, helping manage liabilities before development or purchase.
What is the difference between Phase 1 and Phase 2?
Phase 1 is a desktop and site walkover study identifies potential risks. Phase 2 collects soil, water, and gas samples to confirm actual contamination.
How long does a Phase 1 Environmental Report and Phase 2 Site Investigation take?
A Phase 1 takes 10 days. A Phase 2 takes 4-6 weeks depending on complexity.
What happens if contamination is found during a Site Investigation?
A remediation strategy is developed to remove or manage the risks to acceptable levels.
Do I always need a Phase 2 investigation?
Not always — if Phase 1 finds no significant risks, Phase 2 may not be necessary.
FAQs About Contaminated Land Assessments
What’s a Ground Gas and Vapour Strategy (GGVS)?
A GGVS is a targeted investigation to assess the presence and risk of gases such as methane, carbon dioxide, and vapours. It typically involves installing monitoring wells, conducting several monitoring visits, and using standards like CIRIA C665 and BS8485 to determine whether protection is needed.
Do I need gas monitoring for a small extension in RBKC?
Not necessarily. If the Phase 1 Ground Gas Risk Assessment confirms no credible risk — for example, if the site is underlain by intact London Clay with no Made Ground — monitoring may not be needed. In low-risk situations, RBKC may accept the installation of basic gas protection measures with a verification statement instead.
How long does a ground gas investigation take from start to finish?
The monitoring phase typically requires 3 - 6 visits spread over a few weeks, depending on site complexity and weather pressure conditions. Including report preparation, the whole process can take around 6 - 12 weeks.
Can I reuse historical ground gas data for planning?
Yes — provided the data is recent, reliable, and representative of current conditions. Clear Environmental reviews historic site investigation records early to help reduce costs and avoid unnecessary repeat monitoring.
What happens if gas risks are confirmed?
If gas concentrations exceed safe thresholds, you’ll need to install mitigation measures such as membranes, venting layers, or structural barriers. Clear Environmental will design a practical, proportionate solution and prepare the necessary Remediation and Verification reports.
What should be included in the Ground Gas Verification Report?
The Verification Report must include photographic evidence, product specifications, a signed statement of installation quality, and confirmation that gas protection was installed in accordance with RBKC expectations. For some projects, additional tracer gas testing may be required.
