A major error in the marking of English language exams used for UK visa applications has resulted in thousands of candidates receiving scores that did not reflect their actual performance, raising questions over how many migrants entered the country without meeting language requirements.
The Telegraph reports that the problem affected the International English Language Testing System (IELTS), a widely used exam run by the British Council, Cambridge University Press & Assessment and IDP. The test is taken globally by people seeking to study, work or migrate.
Technical Fault Affected Around 78,000 Scores
Reports cite that IELTS confirmed that listening and reading results issued between August 2023 and September 2025 were impacted by what it described as “a technical issue.” Although the organisation said only about one per cent of tests were affected, this is estimated to equal around 78,000 results.
The mistake was detected only recently. IELTS said it had since contacted all those involved “to provide updated results, to offer our sincere apologies, and to provide appropriate support.” Some candidates received higher marks than they achieved, while others were given lower scores.
Because the error went unnoticed for more than a year, applicants with inflated scores may already have used the results to secure UK study or work visas.
Ongoing Concerns About English Proficiency
The incident adds to concerns about English standards among overseas applicants in education and health services. Telegraph information that university staff have previously warned that some institutions admit students whose language abilities do not match course demands. Reports from academic unions suggest many lecturers believe international students often struggle with English.
In the NHS and social care, coroners have highlighted cases where inadequate language skills contributed to serious incidents. One case described by The Telegraph involved a care worker who had never taken an English exam and misinterpreted key words during a 999 call, including confusing “breathing” with “bleeding.”
Shadow home secretary, Chris Philp, said the situation shows “up to 78,000 people may have received incorrect language test results before being granted visas.” He added: “Those who obtained visas improperly must be removed,” arguing that lack of English prevents integration.
Cheating and Leaked Papers in Multiple Countries
Separate from the marking fault, cheating has been reported in China, Bangladesh and Vietnam. Criminal groups have sold leaked IELTS papers to candidates ahead of exams. In Bangladesh, police arrested two individuals accused of charging £1,000 to £2,500 for advance test papers obtained through bribery.
In Vietnam, a scheduled exam was replaced with a backup version earlier this year after concerns about a leak. The British Council said there had been increased attempts to sell stolen exam materials. Similar activity has been noted in China. Some UK universities have paused student recruitment from Bangladesh and Pakistan due to concerns over visa abuses.
Financial Pressure and Government Scrutiny
Independent MP, Rupert Lowe, has sought details from the Home Office on fraudulent IELTS certificates identified over the past five years. Officials said retrieving the information would be disproportionate in cost.
Reports inform that the British Council, which relies partly on income from English testing, is still repaying a £197m Covid-era government loan. Any compensation claims linked to the scoring error may place further strain on its finances.
The Home Office is currently awarding an £816m contract for English testing services. The British Council is expected to compete with other providers.
An IELTS spokesperson said all affected candidates had been contacted and that steps had been taken to prevent this issue from happening again.
