Statutory guidance

Bats: survey or research level 1 licence (CL17)

Updated 23 July 2024

Applies to England

Class licence CL17: to survey bats of all species for science, research or educational purposes - Level 1.

Overview

This licence permits the surveying of bats by observation only (including the use of artificial light, in the form of torches but not endoscopes).

This licence can only be relied upon where surveying is carried out for scientific, research, or educational purposes, including informing development projects, and users must comply with licence terms and conditions at all times. The licence conditions include a requirement to submit a report of licensed activities each year.

This licence does not permit activities licensed under the Volunteer Bat Roost Visitor licences (WML-CL15 and WML-CL16), which persons registered to act under these licences may rely on when undertaking official duties under Natural England’s Bat Advice contract.

This licence is Level 1.

It can be used by Registered Persons and Assistants under their direct supervision, wishing to carry out a basic presence / absence survey. This licence permits any reasonable disturbance associated with confirming if bats are present in a bat box (if no handling is likely to be required) or if a bat roost is present in a structure, estimating numbers and identification of species, so long as this does not involve handling bats or disturbing hibernating bats. Registered Persons are expected to act in a responsible manner and when the necessary information is collected to withdraw without causing further disturbance.

A Level 2 licence is required if you wish to handle bats whilst surveying, including when checking bat boxes.

A Level 3 or Level 4 licence is required (see Information and Advice note a) if you wish to use mist nets or harp traps, including the use of lures where appropriate, whilst surveying to inform development proposals.

Should you wish to use additional equipment such as rings and tags, or to use mist nets or harp traps and lures outside the remit of the Level 3 or Level 4 class licence, then a project licence must be applied for: https://www.gov.uk/get-a-wildlife-licence.

Registration: Anyone wishing to use this licence who does not currently hold a personal bat survey licence must first apply to Natural England to be registered.

Recording and reporting: There are data recording and annual reporting requirements.

Reference: WML – CL17.

Important

This licence authorises acts that would otherwise be offences under the legislation referred to above. Failure to comply with its terms and conditions:

i. may be an offence against the Habitats Regulations or the 1981 Act, or mean that the licence cannot be relied upon and an offence could therefore be committed. The maximum penalty available for an offence under the Habitats Regulations or 1981 Act is, at the time of the issue of this licence, an unlimited fine and/or a six month custodial sentence

ii. may result in your permission to use this licence being withdrawn. Natural England will inform any person or organisation whose permission to use this licence is withdrawn in writing. This sanction may be applied to other similar licences

iii. may mean that you are not able to rely on this licence as a defence in respect to the prohibitions within the Animal Welfare Act 2006 or the Wild Mammals (Protection) Act 1996.

Breaching a condition of a licence issued under the 1981 Act is not in itself an offence but doing so may mean that the licence cannot be relied upon and an offence could therefore be committed. If the activity that you wish to undertake is not covered by this licence, or if you are unable to comply with any of the terms and conditions which apply to the use of this licence, then you will need to apply to Natural England for an individual licence.

This licence is not a consent for the purposes of Part II of the Wildlife and Countryside Act 1981 (as amended) in respect to SSSIs. It is your responsibility to get consent or assent if required before this licence can be used on any SSSI. See Advice (u - w) for further information.

Issued by and on behalf of Natural England on 1 January 2024.

Information and advice specific to this licence

Coronavirus – Best practice

To avoid transmitting COVID-19 from people to wild mammals, you should: stay at least 2 metres from live wild mammals at all times; only capture or handle live wild mammals if necessary; and avoid going within 2 metres of known breeding or regularly used resting sites of mammals. If you cannot follow these guidelines, then you should minimise the time spent in close proximity and handling mammals; limit the number of people that come into close proximity or handle mammals; and keep animals separate from other individuals as far as possible.

i. Persons acting under this licence should follow good hygiene practices, including wearing of disposable gloves, or clean and disinfected non-disposable gloves; wearing a face covering when handling and in close proximity to any mammal; and washing hands before and after close proximity or handling of any mammal. Face coverings, non-disposable gloves and overalls or other clothing should be washed / disinfected between uses when handling mammals.

ii. You should not carry out activities under this licence if you feel unwell, test positive for COVID-19 or live with someone who has or might have COVID-19.

iii. Any products used to clean and disinfect equipment should be safe for use where there could be contact with animals and used at an effective and safe dilution rate. ‘Safe4’ is considered to be an appropriate disinfectant for this purpose and is considered effective against the virus at a dilution of 1:50. Other products can be used to clean and disinfect equipment.

Level 1, Level 2, Level 3 and Level 4 Bat Class Survey Licences

a. There are four levels of Bat Class Survey Licences. These differ in the methods of surveying permitted:

• Level 1 (reference WML-CL17) permits surveying which may result in disturbance only (it permits the use of artificial light, such as torches).

• Level 2 (reference WML-CL18) permits surveying by hand, with hand held static nets, artificial light, such as torches, and endoscopes.

• Level 3 (reference WML-CL19) permits additional survey methods using mist nets and acoustic lures.

• Level 4 (reference WML-CL20) permits the use of harp traps and acoustic lures.

This is the Level 1 survey licence.

To register to use the Level 2, Level 3 and Level 4 licence you require additional experience and/or training https://www.gov.uk/government/collections/bat-licences.

A project licence will be required should you wish to use mist nets and/or harp traps with or without lures for more than three days at any one site, or for purposes other than to inform development proposals, or should you wish to use rings or tags or otherwise mark bats.

Guidance on surveying

b. The Bat Workers Manual is available from the JNCC website.

The UK Bat Mitigation Guidelines is available on CIEEM website. 

Bat Surveys for Professional Ecologists: Good Practice Guidelines (4th edition) is available on the Bat Conservation Trust’s website.

You will be expected to check whether this guidance has been updated and if so, to ensure that you act in accordance with the most up to date version.

c. Before exercising this licence the licensee should liaise with the appropriate local bat groups if undertaking surveys on a site which a local bat group has an interest in. For help finding local bat groups see - https://www.bats.org.uk/support-bats/bat-groups.

Relevant legislation and good practice

d. Persons acting under this licence may photograph bats in connection with licensed work provided that this causes no additional disturbance.

e. Although this licence does not permit handling bats, should an injured or dead bat be discovered you should only handle the bat if you are wearing appropriate gloves and have an up-to-date vaccination against rabies.

f. A licence is not required for the short-term keeping of injured bats that were obtained legally for the purpose of tending them in order to release them when no longer disabled. However, if the bats are to be kept for longer than six months then the carer should apply for a licence to possess bats. This can be done using the possession licence application form WML-A37.

g. Persons acting under a licence should have regard to legislation and good practice relevant to the action(s) undertaken, including animal welfare and the Animal Welfare Act 2006 (2006 Act). It is an offence to cause any unnecessary suffering to an animal (including birds) under the control of man (section 4 of the 2006 Act).

This applies to the humane dispatch of captured animals and the treatment of animals held in traps or nets, including decoy birds and non-target animals. The application of Animal Welfare Act 2006 to wildlife management activities is explained in Natural England leaflet Wildlife Management Advice Note: The Animal Welfare Act 2006: what it means for wildlife (WML-GU02).

Biosecurity

h. Users of this licence should consider the risks of activities to biosecurity and take relevant precautions when visiting heathland and woodland sites to avoid the spread of invasive non-native species, and tree and plant pests and diseases such as Phytophthora and Ash dieback Chalara.

General biosecurity advice can be found on the GB Non-Native Species Secretariat website.

Further information on plant biosecurity is available on the GOV.UK website.

Information and advice for all class and general licences

General information

o. Natural England checks compliance with licences and the attached conditions. Where breaches are identified, these may be subject to enforcement action.

p. Ordinarily, licences will be reissued on 1 January each year ( you do not need to re-register for those with registration requirements). Please note, however, that they can be modified or revoked at any time by Natural England or the Secretary of State, but this will not be done unless there are good reasons for doing so. You are advised to check the terms and conditions of a licence prior to your first use of it each year in case of amendments.

q. The common name of the species given in a licence is included by way of guidance only; in the event of any dispute or proceedings, it is the scientific name of a species only that will be taken into account.

The limits of licences

r. Licences permit action only for the purposes specified on that licence.

s. Licences do not permit actions prohibited under any other legislation, nor do they confer any right of entry upon land.

t. Unless otherwise stated the provisions of Natural England licences only apply landward of the mean low water mark in England. The Marine Management Organisation is responsible for all licensing seaward of the mean low water mark.

Protected sites

u. You can search for and view details about all SSSIs by using Natural England’s Designated Sites system. The notification documents for each SSSI contain a list of operations that require Natural England’s prior consent.

Owners and occupiers of land notified as SSSIs are required to give written notice to Natural England before either beginning any of these operations, or allowing someone else to carry out those operations. SSSI consent can only be given to a SSSI owner or occupier. It may be given with or without conditions, or in some cases, consent may not be granted.

A similar process applies to public bodies and statutory undertakers (as defined under Section 28G of the Wildlife and Countryside Act 1981 (as amended)) and this obligation applies even where the operations are carried out on land outside of the SSSI.

v. Please note that as the licensee you will not be able to undertake the licensed activity on a SSSI until the owner or occupier of the SSSI has applied for, and received, Natural England’s written SSSI consent. If you do so, you may be at risk of committing an offence.

As the licensee, if you wish to exercise this licence on a SSSI you must contact the relevant owners or occupiers of the SSSI and ensure they give written notice to Natural England of their proposal to permit you to carry out licensed activity on their SSSI. You should wait until a SSSI consent decision has been received by the SSSI owner/occupier before you begin to exercise this licence on a SSSI. See GOV.UK for further information on how to get SSSI consent from Natural England.

w. In considering whether to issue consent or assent for activities likely to affect a SSSI that is a European Site, in other words a Special Protection Area (SPA) or Special Area of Conservation (SAC), Natural England will carry out a Habitats Regulations Assessment, as required by the Conservation of Habitats and Species Regulations 2017 (as amended) (‘the Habitat Regulations’) to ensure there will be no adverse effects on the European Site.
