The Bat Earned Recognition (ER) Pilot Project is a partnership project between Natural England (NE), the Bat Conservation Trust (BCT) and the Chartered Institute for Ecology and Environmental Management (CIEEM). The project will implement a scheme of professional accreditation for applicants for bat mitigation licences. The aims of the scheme are to (1) streamline licensing, (2) raise and maintain professional standards in bat mitigation work and (3) improve outcomes for bats.


The period for Site Registration submissions under the Bat Earned Recognition (ER) Class License by ER Pilot Accredited ecologists has now been extended to the end of December 2022. This will enable accredited ecologists to submit as many Sites Registrations under ER as possible, and thereby allow robust testing of the pilot materials and processes to the fullest.

A detailed evaluation of the Pilot to date will be undertaken in August 2022, with further findings captured, following on from this, until Pilot end Dec 2022 and iteratively feeding into an upscaled and improved model - ‘Bat ER Beta’.

Bat ER Beta will include a further round of accreditation testing for ecologists (Jan-Mar 2023) making use of, and testing, improved materials and systems. This is an important step in the potential move to full ER roll out.


On 21 January 2022 the Bat Earned Recognition (ER) Pilot opened the ER Site Registration portal. Ecologists successfully accredited under the competency testing process of ER are now able to submit Site Registrations and take full advantage of the benefits of their Earned Recognition status. This includes a streamlined Site Registration (‘licence application’) service as well as vastly increased autonomy to undertake licensable bat mitigation works compared to the traditional bat mitigation licensing system.

Accreditation testing of candidate ecologists continues and the number of ER accredited ecologists is expected to grow considerably over the next month. We currently anticipate around 75 ecologists will be accredited. The accreditation and assessment processes of the ER pilot, as well as Site Registration elements, will all be thoroughly evaluated as part of the partnership’s commitment to building a robust and reasonable ER model.

The project team and partnership would like to express their thanks to those that have contributed to this ground-breaking pilot. Your expertise, feedback and experiences are all valuable to us and will be carefully considered as part of continued refinement of the Earned Recognition approach.

The Bat Earned Recognition Pilot has now moved into the exciting stage of starting the assessment of 100 ecologists’ competence through accreditation testing (please note applications are now closed). The project team and partnership would like to express their thanks to those that have applied and shown an interest in this ground-breaking pilot. The pilot had over 200 applicants which has enabled the pilot to ensure a wide range of individuals (e.g. organisation type, years of experience, geographic locations, accreditation level application, etc) are represented in the pilot to help ensure we have as robust and fair a system as possible.

The portal for accreditation testing will open imminently and our team of expert assessors are standing by to begin their assessments. The Project Team will continue to keep you updated as the pilot progresses.

Background - Why Bats?

Applications for licences involving bats and bat roosts are by far the highest proportion of mitigation licence applications received by Natural England and numbers are increasing year on year. The vast majority are lower risk situations but they still need to be licensed which requires time, effort and cost on the part of the developer, the consultant and Natural England. This reduces the resources available for monitoring, enforcement and drawing together the evidence base for the effectiveness of mitigation. Natural England’s resources to put into licensing are stretched and a more streamlined approach would have benefits for everyone.

We believe that an accreditation system would help to improve standards of bat mitigation and lead to better outcomes for bat conservation.

Earned Recognition

Earned Recognition works on the basis of assessing and accrediting a consultant’s competence in undertaking survey work and designing effective mitigation so that, by using an accredited consultant, developers can experience a more streamlined licensing process for their scheme or project.

The competency requirements for consultants are being defined on the basis of relevant selected elements of CIEEM’s Competency Framework (but a more detailed version with a bats emphasis) with the indicators of competence mapped across to BCT’s Professional Training Standards. There will be different competency requirements based on the level of accreditation applied for which, in turn, relates to the degree of risk to bats and bat roosts from the projects that the accredited consultant will be able to work on. Quite simply, consultants who work on projects that involve higher risks to bats will require a higher level of accreditation that involves demonstrating a higher level of competence.

The number of bat species in the UK, together with the variation in their geographical distribution makes this quite a complex system to design, so we have produced some key documents:


Natural England undertook a stakeholder consultation exercise earlier in the project lifecycle but the project partners wanted to undertake a further consultation on the detail of the project, prior to running a pilot.

A detailed consultation for ecologists involved in mitigation licensing was launched on 17th November 2020 and closed on 5th January 2021. The results of the consultation are reported here.

The project partners delivered a webinar for ecologists about the proposed scheme and the forthcoming pilot on 19th November from 13.00-14.00. A recording of the webinar can be found here.

Many questions were submitted before and during the webinar and in the following months. In April 2021 we updated our Q & A document and this version can be found here.

A less detailed consultation for other stakeholder groups, including local authority planners, local authority ecologists, developers, architects, planning consultants, builders and NGOs was also launched on 17th November 2020 but closed on 31st January 2021. The results of this consultation are reported here.
