Bats can often present challenges on development sites. As a protected species, all bats and their roosts are protected from disturbance and damage, the breach of which can result in hefty penalties.
A fine of up to £5,000 per bat and up to six months in prison can be implemented. On numerous occasions, developers and individuals who did not follow legislation or advice have ended up disturbing or destroying bats. An example of this was seen in the news when a property
developer was fined over £10,000 for destroying a bat roost after not following advice and obtaining a license.
