Preliminary Ecological Appraisals, also known as Phase 1 surveys, are usually the basic starting point for most ecology consultancy services of new development sites. Often they are required as part of planning applications prior to permission been approved.
You may have seen the Preliminary Ecological Appraisals (PEAs) process mentioned on other ecology consultancy websites as the only starting point. However, let’s clear things up from the start, they advertise this to ‘bump’ the cost on your phase 1 survey.
Not all development works require a FULL PEA.
Preliminary Ecological Appraisals include a full site assessment for flora and fauna, roost assessments, habitat walkovers, and full biological records data searches costing between £150-500 from a third party.
In reality, for a small domestic development, a FULL Preliminary Ecological Appraisal is unrealistic and is way more than what your local planning office requires. Usually, a simple bird and bat roost assessment or habitat walkover is more than sufficient, saving our clients £££s in fees and time.
All Phase 1 surveys can be carried out year-round.
