How to change an unincorporated association or trust to a charitable company or CIO, plus other types of conversion.

Your charity’s legal structure sets out what type your charity is. There are four common types of charity structure:
- Charitable Incorporated Organisation (CIO) – there are 2 structures: association CIO and foundation CIO
- charitable company (limited by guarantee)
- unincorporated association
- trust
Your charity’s legal structure determines:
- who will run it and whether it will have a wider membership
- whether it can enter into contracts or employ staff in its own name
- whether its trustees are personally liable for what it does
Changing to a different charitable structure usually involves:
- setting up a new charity in the new structure, with purposes that are the same as or similar enough to those of the original charity
- transferring your original charity’s assets and liabilities to the new charity, then
- closing your original charity
This can be complex, particularly if your charity has assets which are permanent endowment and you should take appropriate professional advice. For example, on the transferring of assets, contracts or liabilities, or where your charity has permanent endowment.

The main advantage of CIOs over charitable companies is that CIOs don’t have to register with and send accounts to Companies House as well as the Charity Commission.
You must choose a business structure if you’re starting a business that helps people or communities (a ‘social enterprise’).
