open university after withdrawing from brick university

So I completed my first year of a psychology undergraduate course at a brick university last year and moved onto second year this year, but I can’t continue for mental health reasons and am in the process of withdrawing.
I plan on transferring my credits and continuing to study with the open university. This should mean that i’ll be studying for two years until I get my degree.
I understand that even if I study full time with the open university, it is still classed as part time with student finance, but I’m just wondering how it will work as I’ve seen that I should only be entitled to 1 year of funding if my course lasts two years since i’ve technically studied two years in student finance’s eyes, but this information is based off of the idea that I’d be going back to a brick university with full time tuition fees but it is different.
Does anyone know if they apply the same logic if you’re withdrawing and switching to study what is classed part time?
If anyone knows how SFE or SFW works please help!!
