National Insurance is a system in the United Kingdom that helps fund various social security benefits. People contribute to this system through deductions from their earnings, which helps provide financial support for things like pensions, unemployment benefits, and healthcare. Essentially, it’s a way for workers to contribute to a safety net that supports them and others in times of need. When you start a job, your employer usually takes care of your National Insurance contributions. These contributions are important because they ensure that you can access benefits when necessary, such as during retirement or if you become ill and cannot work.
