In certain circumstances, individuals may not have to pay a fee. A system known as the remission system is available to those who would have difficulty paying a fee and meet the appropriate criteria.

You can receive fee remission  if you are on certain benefits ( JSA, ESA, IS, UC ) or are on a low gross monthly household income (under around £1700 for two adults/two children)
