English Chess Federation grades are only published twice a year, in January and July. All games played in graded events can be checked on this database.
To look up your grade, grading history look at the English Chess Federation's grading database page.
Search for your name, e.g. Raoof. You will find your grading record, with the following fields; grading reference / code as the first column, then your ECF membership status, then your name, gender, club, standard grade / last year's standard grade, rapid grade / last year's rapid grade.
If you click on your grading reference number this takes you though to your entire grading history! For instance this is my grading history.
UNGRADED PLAYERS - if you have never played in a tournament before, then you won't have a published grade. However you may still have a grading code and you can still check your grading history. Search for your name, then expand the menu selection at the top to include "ungraded players". Then you can find your record.
