I understand it depends who will be providing the service. Eg for me it would not be needed. I could ask for a re-assessment but this would be taken in the context of arranging services from my local authority and would not be relevant to me arranging services via private providers, unless it involved financial support that I was looking for. As for a my local befriending provider, they offered to complete their own assessment. The last one I had done with the provider was very straightforward, we discussed the original local authority assessment and this gave them some back ground info. The matching of the befriender based on their own assessment worked out well.
