Probably not in their base $ or € amount. However, with the continued weakening of the £, you may find the charges are now slightly higher when translated to GBP. It will depend on which airlines you're looking at.

In this instance it won't make any difference as you're changing the outbound before the date of departure. Where it makes a real difference is if you want to change your return journey after you've taken the outbound. In such a case, you can only do that if you've booked as two one ways.

Shouldn't be necessary.
