Use Case: Environmental Risk Screening
Screen Environmental Risk for Any UK Site
Check flood risk, contamination, radon and coal mining risk in one search — a fast first-pass alternative to ordering separate environmental searches.
What This Workflow Covers
Environmental risk screening means checking a site against the range of official hazard datasets that could affect its safety, insurability or development potential — flood risk from the Environment Agency, contaminated land and historic land use, radon risk from the British Geological Survey, and coal mining risk from the Coal Authority. Maplify brings every one of these into a single map search, rather than requiring separate lookups or a paid third-party search for a first-pass check.
This workflow is used by surveyors, developers, environmental consultants and property buyers who need to understand a site's risk profile quickly before deciding whether to commission a fuller, formal assessment.
Traditional Method vs Maplify
| Task | Traditional Method | With Maplify |
|---|---|---|
| Check flood risk | Search the Environment Agency flood map service directly | Flood zone data available as one of many layers on the same map |
| Check contaminated land | Contact the local authority for a contaminated land register extract | Contaminated land layer shown instantly on the map |
| Check radon risk | Order a radon report from the British Geological Survey | Radon risk layer included on the same platform |
| Check coal mining risk | Request a Coal Authority mining report | Coal mining risk shown as a map layer, no separate request needed |
| Cost per site screened | £30-£60 per formal search report | Included in your Maplify plan |
Why It Matters
Environmental risk factors can materially affect a site's insurability, construction cost and even its suitability for certain uses — a site with contaminated land history may need remediation before development, and one in a Coal Authority high-risk area may require additional permissions. Catching these factors early avoids costly surprises further into a transaction or project.
For professionals advising clients, a documented environmental screen also demonstrates due diligence was carried out, which matters if a risk factor is later disputed or challenged.
Worked Example
A developer is assessing a former industrial yard for potential residential conversion.
- The contaminated land layer flags the site as having a historic industrial land use record.
- Coal mining risk data shows the site sits within a former coalfield, though not a current high-risk development area.
- Flood risk is low, reducing one potential concern for the scheme.
- Based on this, the developer commissions a formal ground contamination survey before progressing further, rather than discovering the issue later at a cost to the project timeline.
How to Get Started
- 1Search the site address or draw a boundary on the map.
- 2Switch on flood risk, contaminated land, radon and coal mining risk layers.
- 3Note any flagged risks and their potential implications for the site.
- 4Commission a formal search or specialist assessment for any risk that warrants further investigation.
- 5Export a summary to include in a due diligence or feasibility report.
This is general guidance, not professional or legal advice — confirm specifics with the relevant authority or a qualified professional.
What's Included
Important Limitations
- Maplify is a first-pass screening tool — a formal, insured environmental search report is typically required for mortgage lending or planning submissions.
- Environmental risk layers reflect the currently published designations and should be checked against the latest source data for high-value decisions.
- A flagged risk does not necessarily prevent development or a transaction — it indicates further investigation may be warranted.

Frequently Asked Questions
What environmental risks should I screen for a UK site?
Flood risk, contaminated land, radon, coal mining risk, source protection zones and nitrate vulnerable zones are the most commonly checked environmental factors for property and development sites in the UK.
How does Maplify screen environmental risk?
Search a site on Maplify and switch on the relevant environmental layers — each sourced from the responsible UK government body, including the Environment Agency, the Coal Authority and the British Geological Survey.
Does Maplify replace a formal environmental search?
No. Maplify is a first-pass screening tool. A formal, insured environmental search report is still typically required for mortgage lending or a full planning application, but Maplify helps you decide quickly whether one is worth commissioning.
How do I check contaminated land risk for a former industrial site?
Maplify's contaminated land layer shows registered contaminated land and historic land use data, helping you identify sites that may require a more detailed ground contamination assessment.
Can Maplify tell me if a site is at risk of coal mining subsidence?
Yes. The Coal Authority's coal mining risk data is available as a map layer, showing whether a site falls within a Development High Risk Area requiring further Coal Authority permission or investigation.
How much does environmental screening cost with Maplify compared to a paid search?
A single paid environmental search report typically costs £30-£60 per site; screening the same risk factors on Maplify is included in your plan, letting you check many more sites for the same cost.
