Mk7.5 thermostat housing gaskets coolant leak

I’ve re edited this post
I have coolant leak on right side of engine just above bell housing, coolant level warning light came on. I checked engine bay and it seemed nothing obvious until I noticed that coolant had been weeping collecting onto the bell housing.
Having read a few posts now it’s apparent coolant leak is a common issue mines leaking oil on the right side of engine when standing in front of car.
Cars lost half litre and did not overheat. The hoses don’t seem to be leaking. Having read numerous posts stating that the housing is a common issue. Is it the gaskets that perish ? Because I managed to find a supplier for the gaskets ? I don’t fancy purchasing a whole housing just because of gaskets or is it the case the housing warps ?
My housing seems to be made of metal not plastic.

I’ve attached pic of replacement thermostat waterpump housing and the replacement gasket and link for gaskets anyone with similar issue.
Someone pls advise if I can get away with just replacing gaskets

thanks in advance
