Council chiefs have given the green light to a £234,256 package of fire safety measures at Farsley Farfield Primary School.
The works will be carried out during the 2022 school summer holiday period, due to the extent of the works required and the length of tender process.
A council report says some of the external wall, window and door replacements and Kitchen Ventilation works may require planning approval.
Walter West Builders Ltd will carry out the work, which was initially set for last summer.
Money comes from the council’s Planned Maintenance Programme, which sees the local authority focus on maintaining six key areas at schools These include fire safety, mechanical services; roofing works, external wall, windows and door replacement, kitchen ventilation and demolition.
