Hi
Charitable status has no relevance for VAT purposes.
You must charge VAT to any company or individual unless they provide you with what is known as a "Vat exemption certificate".
If you have supplied a service, I suppose that the customer can say which part of the entity should be invoiced.
Charities may [broken link removed] on the following activities, but that is up to them. You must still charge them VAT:
1. Organisations involved in the transport of severely and permanently
physically disabled persons
2. Radios for the blind
3. Appliances for use by Disabled Persons
4. Sea rescue craft and equipment
5. Humanitarian Goods for Export
6. Donated medical equipment
7. Donated Research Equipment
