Frequently Asked Questions

How Long Will it Take?

Standard Data Enquiries

Point searches (i.e. circular search around grid reference) are a set price and results will be delivered via Aderyn within five working days of receipt of a completed DERF.

For polygon searches (i.e. a buffer applied to a site boundary) we will provide a quote to you within three working days of receipt of a completed DERF. Once the quote is accepted, we will provide your report within five working days.

During our busy periods, it may therefore take a total of 8 working days from submission to completion of a polygon search. Please make allowances for this when planning your enquiry.

BARB Enquiries

Bat And Roof-nesting Bird (BARB) searches are a set price and results will be delivered via Aderyn within five working days of receipt of a completed DERF.

Fast Track Enquiries

If you have a very urgent enquiry, please get in touch with the team to discuss turnaround times. A fast track fee may be chargeable during busy periods.

Non Commercial (Public / Student) Enquiries

You will receive your report within ten working days of receipt of a completed DERF.


What Information Will I Receive?

All reports will be provided via Aderyn.


How can I Share/Use the Data Provided by SEWBReC?

Raw data must not be shared beyond individuals listed on page 2 of a DERF. Some plots may be shared, depending on the content. Data must be destroyed / deleted after 12 months. Please read our Guidelines for SEWBReC Data Use document (PDF) for further information.


Does my client have an SLA with you?

If your client is Natural Resources Wales (NRW) or Dwr Cymru Welsh Water (DCWW), then you do not need to come to SEWBReC for data. Service Level Agreements with these organisations grant them full access to our data, which they can share direct with contractors for relevant projects. Please contact your client direct for relevant data if they are NRW or DCWW.


I work for a Local Authority or charity, how do I access data?

Please complete and email us a DERF if you work for an Local Authority or charity and require data, stating what organisation you work for. You will be provided data via Aderyn in the same manner as commercial enquiries, but the price will be lower. Details of the pricing structure for such enquiries can be found in our charging policy. If you are consultant with a charitable / local authority client, lower prices will also apply but we will need confirmation from your client.


How Can I Prove a SEWBReC Data Search has been Carried Out?

On occasion we have been asked how a consultant could prove that they have undertaken a SEWBReC data search without sharing the raw data supplied by SEWBReC. We now provide you with a unique reference number which you can quote in all correspondence and within your ecological report. This reference number will prove that you have undertaken a SEWBReC data search, as any interested parties (e.g. a Local Planning Authority) can contact SEWBReC direct to confirm a data search was carried out.
