Child Maintenance Service IT failures cause widespread overcharges and distress for parents
A whistleblowing caseworker says persistent IT glitches at the Child Maintenance Service lead to frequent miscalculations, overcharging parents and driving some to suicidal distress.
A current CMS caseworker disclosed that chronic IT problems are causing systematic errors in child maintenance calculations, with an estimated one in five figures being incorrect. The system, described as “the worst I have ever seen,” often breaks during automated updates or bi-monthly Sprint upgrades, producing inflated arrears and erroneous letters. Workers are mandated to enforce payment despite knowing the amounts are wrong, and dealing with callers expressing suicidal thoughts has become a core part of their training.
Past investigations revealed agency correspondence attributing wrong demands to technical faults and instances of parents receiving vastly different payment notices within days. The Department for Work and Pensions maintains that the system is 99 % accurate and that no systemic IT faults have been proven, while also emphasizing the right to challenge decisions and the agency’s safeguarding procedures.
Why it matters
Faulty maintenance calculations can push vulnerable families into severe financial and mental-health crises.
