Two old Zurich-managed pensions funds with vastly different AMC - should I consolidate

Have two Zurich-managed pensions funds from previous employments (say A & B / values are as per today / there might be more than one actual fund being used)
Fund A has an annual management charge (AMC) of 0.3% and a fund value of around 64K Euro
Fund B has an AMC of 0.9% and a fund value of around 89K Euro

Fund B only started last year or so, as the trustees decided to move the pensions from former employees from New Ireland to Zurich.

My current (and active) pension plan with my current employee (Fund C) is with Willis Tower Watson.
This is made up of 2 funds, with an ongoing charge of 0.21% and 0.15% respectively
(I have a pension from an even older previous employer [Fund D], which is also WTW and has the same investment funds as Fund C - so no need to do anything there really)
Both Funds C&D have higher values than A or B (>100K each)
On paper, and ignoring actual fund performance for a moment, it would be a no-brainer to move the two Zurich managed moneys to the currently active WTW pension.
I am aware of the reduced flexibility to get my hands on some of the moneys (I am over 50 already), but I foresee no real need for it as we are lucky enough to have other savings.

So maybe I just move Fund B due to the (high!) AMCs?

I am missing something here?

Your not missing anything.
The main decider on whether to merge pensions should almost always be fees.
On 89K over 20 years the difference between a scheme with a fee of 0.9% vs a fee of 0.18% (i.e. average new fee) will be ~ €42,129
On 64K over 20 years the difference between a scheme with a fee of 0.3% vs a fee of 0.18% (i.e. average new fee) will be ~ €5,323

All the other factors (fund choice, flexibility, ease of managing less schemes etc.) should only become serious factors if the fee difference is negligible (0.1%).

Thank you AJAM. I didn't run actual numbers but that looks like a lot of margherita's for sure!
Time to look at the paperwork involved methinks.
