Home Group has contacted around 4,000 residents after the housing association discovered a “possible data vulnerability” in its IT systems.
The 55,000-home association, which operates across England, said that it sent letters to residents last Thursday to alert them to the issues, after a cybersecurity expert contacted it.
The specialist had found a log that contained personal information for 11 customers, including addresses.
Home Group said the log did not include financial information and no one had stolen any of the data. It also said there was no evidence that the log had been used in any way.
The association added it had fixed the issue less than two hours after being made aware of it.
Home Group said it contacted residents from several of the regions in which it operates.
This is the second high-profile data issue at a housing association this year. Bromford Housing Association leaked the personal information of 253 tenants when it mistakenly sent letters to their previous addresses.
John Hudson, chief financial officer at Home Group, said: “At Home Group, we take the safety and security of our customers extremely seriously.
“We were made aware of a possible data vulnerability and immediately responded to and resolved the issue. This involved a very small proportion of customers, did not include any financial data and no customer data has been stolen.”
