I was communicating with the datacentre support discussing alternative solutions and they said the only option to allow a larger database was to obtain a root server instead of a managed server. I took a look but currently their cheapest root server is £90 + vat pwr month, compared to £35 + vat for the new managed server. Amibay donations only allow £50 pm max so that's a non starter. Plus the amusing thing is the hardware the cheapest root server is based on is using a CPU that came out 8 years ago! Complete rip off.
