my transformer has a secondary winding of 0 - 12v - 24v
Is it just labelled differently and is it really a center tap where 12v would be the center, 0 would be -12v and 24 would be 12v?
Thanks!

It's not an autotransformer is it (basically just a big inductor with multiple output taps)? You can check by measuring resistance to see if the 0V and 0V are electrically connected to each other

Not necessarily. If the transformer is rated to produce full output from either the 12V tap or the 24V tap, it could be that the winding from the 12 to 24V terminals is of a finer gage, since the current that could be drawn from the 24V tap would be half that you could draw at 12V. This you can determine by comparing the resistance of the 0-12 and 12-24 windings.
Would that matter for using it as a center-tapped +/- 12V transformer? Not much, the terminal voltage at the high side would be fractionally lower under load, but the overall heating compared to drawing the full power at a single tap would actually be less.

I'd think so. While you can get more out of a given core (since you have to get all the windings through a fixed window size) by fine-tuning the wire sizes, there's the additional cost of winding different wire sizes, so keeping the windings the same is likely cheaper. More effective still for a 12V OR 24V secondary is to have two separate winding that can then be connected series or parallel to maximize winding utilization.

This you can determine by comparing the resistance of the 0-12 and 12-24 windings.
Would that matter for using it as a center-tapped +/- 12V transformer? Not much, the terminal voltage at the high side would be fractionally lower under load, but the overall heating compared to drawing the full power at a single tap would actually be less.

so you can relabel with 3 choices;
0 : 12Vac : 24Vac
12Vac : 0V : 12Vac +180 deg
24Vac : 12Vac : 0V

It's not an autotransformer is it (basically just a big inductor with multiple output taps)? You can check by measuring resistance to see if the 0V and 0V are electrically connected to each other

@Toor thanks will check, in the mean time their website in french clearly makes a distinction between a regular transformer and autotransformer and the label says "transformer" so I would guess this is not an autotransformer. Getting the multimeter..

@Toor Can confirm: 0 and 0 are not connected to each other.. 0 and 12 and 24 are on the secondary, obviously 0 and 220 are on the primary side

Yeah, so a normal center-tap transformer just labelled specifically for its intended use then.

You can. Just note that one half-winding will be loaded a more than the other half and will affect both voltage outputs.
