Public IP Subnet - UK

We co-locate a large amount of equipment in a UK DC, the DC provider leases us a /26 IPv4 subnet. I have been looking into the possibility of getting our own IP space for a number of reasons:

- If we wanted moved DC providers, we would have to re-IP all equipment
- Some services would be next to impossible to migrate, for example 250+ SIP Phones out in the field hard programmed with endpoint IP Address (no way of using DNS, handset limitation)

Looking online you can either purchase IP space (around $40 per IP - /24) or be added to the RIPE waiting list (if you're organization has never had an assignment before) and hope that over the next year or so, someone releases IP space and RIPE allocate it to you.

As much as we'd love a /24, we only really need a /26. However, I believe a /24 is the smallest amount of IP space you can "own" due to BGP Routes, is this correct?

In addition to this acquiring the IP Space (waiting or buying), am I right in thinking we would need to become a RIPE LIR Member and pay their 2000 EUR fee for the first year, and then 1400 EUR per year there after?

Is there a cheaper way of going about having your own (small) block of IP Space? I have looked into "renting" IP Space and getting our current DC provider to announce this on their network (which they would be happy to do), however it seems to be a minefield in terms of if the IP Space is clean and with a good reputation etc.

Would value anyone's ideas.
