Do You Need a Phase 1 Desk Study for Planning Permission?
When applying for planning permission, many developers are surprised to learn that they must first complete a Phase 1 Desk Study. But what exactly is it—and why is it so important?
🔍 Why Local Authorities Ask for It
Planning departments request a Phase 1 Desk Study when:
🏭 The site is on or near a former industrial area
🗑️ There’s a possibility of past contamination
🏡 The development changes land use (e.g. commercial to residential)
🌊 There’s potential risk to water sources or ecosystems
The study ensures environmental risks are identified early—before ground is broken.
📚 What’s in a Desk Study?
The report typically includes:
👣 Site Walkover – Inspecting the land for signs of past use, pollution, or hazards
📜 Historical Review – Looking back through maps and archives to identify risks
📈 Data Analysis – Reviewing environmental databases, flood risk zones, and nearby contaminated land
🧱 Geology Overview – Analysing underlying geology and groundwater movement
📊 Conceptual Site Model (CSM) – Visual summary of risks and exposure pathways
If potential risks are identified, the report may recommend a Phase 2 Intrusive Investigation.
⚖️ What Happens If You Don’t Do It?
Failing to submit a Phase 1 Desk Study can result in:
❌ Planning application delays
🔁 Requests for further info from environmental health officers
💷 Additional costs due to poor preparation
🚧 On-site construction delays
It’s far better to address issues upfront than deal with them mid-project.
