Members of the UK Parliament are calling for a complete overhaul of the Child Maintenance Service (CMS) following a series of revelations detailing significant blunders that have allegedly left parents financially crippled, facing inflated charges, and in some tragic cases, driven to suicide.
Campaigners and MPs point to suspected computer glitches and staffing issues as root causes for the long-running problems within the agency. These issues have reportedly resulted in tens of thousands of parents being overcharged, leading some to rely on food banks or become estranged from their children. The CMS is responsible for managing payments between over 800,000 UK parents, aiming to ensure financial support for children when relationships end and they reside primarily with one parent.
One particularly distressing case highlighted involves Jonathan O'Neill, 41, from Huddersfield, who died by suicide after being issued a demand for an additional £4,200. According to his sister, Joanna Smith, the agency continued to send payment demands to his family for months after his death. "It feels like they just don't care, they are not bothered. But it has ripped our lives into bits," Smith stated.
Other accounts include Army veteran Simon Ward, 45, who reported being left "financially and emotionally crippled" and forced to use food banks after his monthly payments surged from £36.40 to £419. Carl Leverett, 48, was informed he owed £77,000.
MPS have reported being inundated with complaints from constituents regarding the CMS, with some drawing comparisons to the Post Office scandal. Liberal Democrat MP Ian Sollom described the situation as exposing a service that "gets calculations wrong and then pursues parents for money they don't owe." He urged ministers to "fix a system that is causing financial harm and emotional distress to families."
Ian Briggs, co-founder of STOPSuicides UK, an organization that highlights CMS failings, noted that the group regularly hears from parents experiencing "overwhelming financial pressure, prolonged disputes and deteriorating mental health, with some reaching suicidal crisis." Briggs suggested the investigation should serve as a catalyst for a public inquiry, reform, and greater accountability.
In another instance, Belzuan Zeka described experiencing panic in late 2025 after receiving four different monthly payment demands ranging from £180 to £3,500. He commented on the apparent lack of accountability for a government agency with significant power.
Michelle Counley of the National Association for Child Support Action (NACSA) corroborated these concerns, stating that the investigation reflects the daily issues they witness, with the system failing to provide timely and accurate calculations, leading to false arrears and unaffordable demands.
Reform UK's Deputy Leader Richard Tice stated that an "institutional reluctance to accept failings has slowly turned into acceptance that it can and should do much better." Vikki Slade, Liberal Democrat MP for Mid Dorset and North Poole, called for "urgent and complete reform" to prioritize children's welfare and financial stability. Conservative MP Rebecca Smith added that "too many families currently feel they are being let down."
The Department for Work and Pensions (DWP), which oversees the CMS, has denied systemic IT glitches within the service, calling such claims "misleading." A DWP spokesperson acknowledged that in 2018, the system experienced slow response times due to upgrades, but asserted these did not impact calculations and were resolved by late 2018. The department stated that receiving multiple letters reflects the automated process of sending new calculations whenever a change is registered, such as a new job or altered overnight care arrangements, which can occur in quick succession. The DWP maintains that payment arrangements are fair, based on income, and that assessment accuracy rates are close to 100 percent. They also noted that decisions can be appealed to an independent tribunal.
Most paying parents are required to contribute between 12 and 19 percent of their income, calculated using HMRC records, until their child completes full-time education or training, or turns 20.
