Costs to add a Class Rating?

[Okavango]

Does anyone know if there's a difference in cost between adding a Class Rating to a PPL or a CPL or is it just the same for both (from recollection ~£82)?

According to this

http://www.caa.co.uk/docs/33/269PLSAmd.pdf

It would be the same cost for PPL or CPL.

To add a a second or subsequent aircraft type or class rating would be £121, variation, renewal or revalidation would be £89.

Thanks. Just played with the CAA fee calculator and using that it gives £121 to add a Class Rating to a CPL regardless against £89 for the PPL. The CPL also requires a 'ratings check' for a further £20.
