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 itโand why is it so important?
๐ Why Local Authorities Ask for It
Planning departments request a Phase 1 Desk Study when:
๐ญ The site is on or near a former industrial area
๐๏ธ There’s a possibility of past contamination
๐ก The development changes land use (e.g. commercial to residential)
๐ There’s potential risk to water sources or ecosystems
The study ensures environmental risks are identified earlyโbefore ground is broken.
๐ What’s in a Desk Study?
The report typically includes:
๐ฃ Site Walkover โ Inspecting the land for signs of past use, pollution, or hazards
๐ Historical Review โ Looking back through maps and archives to identify risks
๐ Data Analysis โ Reviewing environmental databases, flood risk zones, and nearby contaminated land
๐งฑ Geology Overview โ Analysing underlying geology and groundwater movement
๐ Conceptual Site Model (CSM) โ Visual summary of risks and exposure pathways
If potential risks are identified, the report may recommend a Phase 2 Intrusive Investigation.
โ๏ธ What Happens If You Donโt Do It?
Failing to submit a Phase 1 Desk Study can result in:
โ Planning application delays
๐ Requests for further info from environmental health officers
๐ท Additional costs due to poor preparation
๐ง On-site construction delays
Itโs far better to address issues upfront than deal with them mid-project.
