The cost of making sure schools met national standards to reduce Covid risks in East Lothian was more than £660,000 after windows had to be replaced in four primary schools.
A report on the work carried out by the local authority to ensure classrooms had proper ventilation and CO2 monitoring so children could return during the pandemic revealed the additional work needed.
And it revealed 12 primary schools exceeded the CO2 limit introduced for the initial monitoring leading to further interventions.
