Is that all I would need?

You will have to forgive my ignorance as I have an nane fear of magic blue smoke.

Can you suggest any suitable drivers preferably available in the UK? I did find these https://www.cnc4you.co.uk/Microstepp...tepping-CW8060

I will be using the existing 5 and 24V transformers.to power the bb-e
My advise is STOP don't buy a single thing until you have settled on exactly what your fitting or need. Also what you have in the machine already that you can re-use.

Those drives are a little over kill but that won't hurt, however, the advice you have been given regards the drives controlling Voltage is Wrong so ignore it.
Those little motors won't like being run much above 60Vdc so the extra capacity the drives allow you cannot really use, but it's always better to have drives that are under performing than being pushed to there limits.

Regards the transformer then the voltage is about right at 35V giving approx 50Vdc when rectified but the Va rating is a little on the low side, 500Va would be better. 300Va would work for those motors but doesn't leave any room for expansion or larger motors in the future 500Va would.

When you say you have 5 and 24v in the machine are you sure it's DC because if it's the original PSU then they tend to be AC transformer and it gets rectified on the boards for the drives to around 32V.
