i have a default date 15/03/07 on my noddle report. 6 years this march. anyone have any idea, should my credit score much higher after march? after the 6 years have passed, will it have a big impact on my score?

help! first time using these forums... i have just checked my credit report for the first time in ages. i used noddle and have score 1/5 (lowest) there are only 2 accounts on my report - bank account with no negative data and a default with o2 for a mobile phone contract. i've read here that defaults will not be shown on my account after 6 years. the default date with o2 is 15/03/2007. 6 years this march. my question is, after march (and im guessing some extra time before the file will be updated), this default will drop from my account yes? should i expect my credit rating to score higher after this drops? will it have a big impact? i've never had a credit card or store card. only previous credit was a loan from RBS which i now cant see on my noddle report (account was closed more than 6 years i think)
