Preliminary Ecological Appraisal (PEA)

Get In Touch


On small sites local to our office locations you can expect to pay £500.00 plus VAT for a PEA survey and report. For large, complex sites our fees increase to around £2,000.00 plus VAT for a survey and reporting – although in either case it can depend on the complexity of what’s there.

Note; where OS mapping is required for us to include within reporting and to use as a base map for survey work, these will be charged for separately which, depending on site size can be £50 plus VAT to £300 + VAT and on large sites even more.

Ecological Data Searches

Most local authority planning departments will request the inclusion of historic ecological records within our reports. This data is a paid for service, chargeable from the records centre, which we request and pay for on your behalf and then analyse the data and include what’s relevant within our reporting.

You do not have to have this data – and it can be expensive (typically £300.00 plus VAT) but be mindful that if we don’t include it then it may be asked for at a later stage of the planning determination process.


Ideally we like 30-40 days for completion of a survey and reporting but we also recognise that sometimes project timescales don’t allow for that long. We’ll always do our best, and where capacity allows then if we can turn around work quicker then we will. The important bit of information for us is when do you plan to submit for planning, as that should ultimately be what dictates the programme. During the quieter times of the year and when we have more capacity then don’t be surprised to see us on site within a week of instruction!

If you would like further information, to discuss what you think you might need, to ask if we can work quickly for you or just for a bit of advice please get in touch and we’ll be happy to help!

What is a Preliminary Ecological Appraisal (PEA)?

A Preliminary Ecological Appraisal is the first stage of the ecology survey process and comprises an extended phase one habitat of the site, which provides a baseline assessment of the site condition and suitability to support protected species and priority habitats. The report provides the client with a comprehensive assessment of the ecological value on site and makes recommendations for further ecological surveys (If required) to facilitate an Ecological Impact Assessment of the site.


When can a PEA be undertaken?


Some scoping and baseline surveys can be undertaken year round and these surveys may make recommendations for additional protected species surveys which can be constrained by survey guidance informed by the by the life cycle and behaviour of the particular species.

Please see our survey calendar to understand when survey work can be undertaken at your site.

How long does a PEA take?


During quieter times and depending on site size and location, we may have scope to deliver a survey and report within a week or two. For more complex surveys and during the busier times of the year then we may need 30 days for a survey and report issue.

Phase 2 Surveys

Phase 2 surveys relate to protected species and habitat surveys recommended as a result of the Preliminary Ecological Appraisal and provide the baseline details to allow Ecological Impact Assessment, and the application for mitigation licences where necessary. Our in-house consultants can undertake a variety of protected species and vegetative surveys which can be seasonally constrained.
