No, study gaps are not tolerated by UK institutions. When applying for the master's programme, you may have a maximum of 10-12 years of work experience. Starting with the year you graduated, the total number of years of experience will be figured out. If you are applying for a bachelor's degree, you may have 2-3 years of experience. The gap is not permitted; nonetheless, institutions may need you to show your job work to compensate for the missed years.
