Any required COM radio must be 8.33 capable. Any surplus to the required minimum need not be, but must not be used to transmit on 8.33 channels. For non-commercial VFR in the UK, the requirement is for one COM radio.
There's a strong incentive in the UK for airfields to convert their frequencies to 8.33, as the licence fee is about 1/3 of that for a 25 kHz channel. So you may find that, if you're used to a 2 COM-box operation, you'll want to convert the second to 8.33 sooner rather than later for practical reasons.
