Bat Mitigation Class Licence: BMCL


The Bat Mitigation Class Licence (BMCL) can, under certain criteria replace the need for a EUROPEAN PROTECTED SPECIES LICENCE (EPSL) when dealing with bats in England. This affords certain benefits over the latter, most significantly its process speed via Natural England.

  • The BMCL can be used all year round by the Registered Consultant (RC) and requires the RC to register the site concerned.

  • A decision on whether to accept the registration of the site will be made by Natural England within 10 workings days.

  • A site has to be registered a minimum of 3 weeks and no more than 12 weeks prior to undertaking any licensable works.

  • Licences will be granted for the period of the licensable works – usually this is 2-3 months and never more than about 6 months.


  • It can be used where there will be impacts to “no more than 3 of the more common species of bats present in small numbers”.

  • The licence covers common pipistrelle, soprano pipistrelle, brown long-eared, Daubenton’s, Natterer’s, Whiskered and Brandt’s bats. Serotine and Lesser horseshoe bats have recently been added in June 2018 under seperate Annexes.

  • Roost types covered are: Feeding, Night, Day and Transitional roosts.


  • Swarming/mating, maternity, hibernation, satellite, roosts in SAC/SSSIs and various multifunctional roosts and multi-species roost (>3 roosts) are NOT covered.

  • BLICL will not be suitable for most multi-phase developments.

  • Trees are not covered by BLICL.


  • Site survey work must follow BCT survey guidelines and must be up to date; it must be from the “current or most recent optimal season”. Optimal season is defined as May-August.

  • As with a standard EPS licence, appropriate consents must be in place for the works affecting bats and any related planning conditions will need to have been discharged.

  • As these are low impact situations, there is no expectation for compensation to be provided. However, one feature/box for each species/roost affected would be considered appropriate.

  • There is no provision for monitoring with BLICL.

  • The licence is in the name of the RC, not the developer, so the RC is responsible for ensuring things are carried out correctly and must report any problems. Enforcement will come in the form of regular compliance checks.

  • A licence return must be sent with 4 weeks of the licence ending and all records must be submitted to the Local Records Centre.

  • The BMCL is a personal licence that is linked to a Registered Consultant (RC), and any site under BMCL would be in the name of that RC. The RC has the right to retract the BMCL at any time, if any they deem that the legal obligations of personnel on site are not being met.
