UNIONS and campaigners slammed private firms today for imposing crippling maintenance bills on schools locked into Private Finance Initiative (PFI) contracts.

PFI schools are bound by 25 to 30-year contracts with private firms, who own and maintain the schools until taxpayers’ money repays the debt.

Over 900 schools have been built through PFI contracts since the 1990s. The initiative was eventually scrapped in 2018.
