For more than 25 years, a Blackpool resident identified as CW has been pursued by debt collectors for obligations belonging to a Yorkshire man with the same name. The latest episode — four unpaid Ulez penalty charge notices from Transport for London — brought bailiffs to his door to seize goods for a vehicle the DVLA confirmed he has never owned or registered. The root cause is structural: TransUnion, the credit reference agency, repeatedly merged a stranger's credit report with CW's, giving tracing agents his address as a match for debts that were never his. The enforcement chain operated exactly as designed — and that is the problem. When the original PCNs went unanswered by the actual driver, CDER Group, TfL's contracted enforcement agents, ran a credit search, matched the name, found the merged address, and dispatched collection notices. At no point did the system require positive identification of the debtor beyond a name-and-address match sourced from a corrupted credit file. The most remarkable failure was institutional, not algorithmic. CW supplied DVLA written confirmation that the vehicle had never been registered to him or his address. TfL responded to CDER with an email rejecting this evidence: "We cannot consider the evidence as valid." It instructed CDER to continue enforcement. A government agency overruled another government agency's records to pursue the wrong person. CW's attempts to halt enforcement required submitting 13 years of payslips and eight years of utility bills. The stress forced him off work on medical leave. This is the friction cost of a system that places the burden of proof on the wrongly accused rather than on the accuser. Over the years, his address has been supplied to tracing agents acting for more than 20 creditors — all chasing debts accrued by his namesake. Only after the Guardian intervened did TfL apologise and cancel enforcement. CDER paid £500 in compensation for what it acknowledged as "anguish." TransUnion — the upstream source of the data corruption — declined to comment, citing an ongoing Financial Ombudsman Service investigation. This was the third time in three years that TransUnion had merged the stranger's credit report with CW's. The story exposes a deeply extractive enforcement architecture. Credit reference agencies produce identity data with known error rates. Enforcement contractors consume that data without independent verification. Public bodies like TfL outsource debt collection and then reject evidence contradicting the contractor's trace. The individual — who has no contractual relationship with any party in the chain — bears every cost: legal risk, medical harm, reputational damage, and the labour of proving a negative. The £500 payment is not compensation in any meaningful sense. It is the price of being caught. The systemic incentive remains: pursue aggressively, apologise cheaply, and let the wrongly targeted absorb the cost of correction.
