No, they are different.
While Zakat is 2.5% of your wealth, Zakat-ul-Fitr (or Fitrana) is a fixed amount for all Muslims.
Zakat-ul-Fitr refers to the charity given at the end of Ramadan’s last day of fasting. It is compulsory for every Muslim to give Zakat-ul-Fitr before Eid Salah.
For 2021, Zakat-al-Fitr is £5, for every Muslim – adults and children – regardless of personal wealth.
