Hi Simon Jones,
Based on the error described above you are not able to spin up your node in pool as your quota is reached. If you have any compute nodes, the error message "PoolQuotaReached: Pool quota for the account has been reached" indicates that you have reached the maximum number of compute nodes that you are allowed to create in your Batch account. To resolve, you can either increase the quota or delete some of the existing compute nodes to free up space to create a new nodes.
