What funding is available to local authorities towards the maintenance of defibrillators in schools.

Funding for Local Authorities is provided through the annual block grant settlement from the Scottish Government. Local authorities should use funding resources allocated to them in the manner which they believe will best meet local needs and circumstances within their respective areas.
Therefore, decisions on the installation and maintenance of defibrillators in schools is a matter for Local Authorities to consider at the local level.
A number of organisations provide advice and support for the purchasing and maintenance of defibrillators. This includes
