fruitsalad ........MOT is just going back to 2011 .
Don't forget that a motor vehicle doesn't require an MOT for the first 3 years from new. So if the vehicle in question was registered in 2008, You have the full history.
The DVLA online history should go back to 2005 according to the website
"You can only get results for tests done in England, Scotland or Wales since 2005."
