Bringing two charities together is one of the bigger decisions a board of trustees will ever take. It touches governance, finances, staff, beneficiaries, restricted funds, property, contracts and the public face of the cause itself, so it deserves more than a quick conversation at the next trustees' meeting. I'm Brad Askew, and I've put this guide together to help trustees and directors get their bearings before they commit to a merger or acquisition route. The framework that sits behind much of this work is found in the Charities Act 2011, particularly the provisions dealing with the Register of Mergers, but the practical reality goes well beyond statute. On this page you'll find a working overview of how charity mergers are usually structured, what the alternatives look like, the questions a trustee board should be asking, and what tends to go wrong when boards rush. If you'd rather talk it through, the call option below puts you in front of an experienced legal adviser.

Overview

A charity merger is the process by which two or more charitable bodies combine their activities, assets and operations so that they continue under a single charity going forward. In England and Wales this can take several shapes: one charity transfers everything to another and then winds itself up; two charities both transfer to a newly created vehicle; or one charity becomes a subsidiary of another within a group structure.

The route that fits will depend on the legal form of each charity (trust, unincorporated association, CIO, charitable company), the nature of their assets, any restricted funds they hold, and what the trustees on each side want to preserve about their identity and purposes. An acquisition in the charity context isn't a commercial buyout, there are no shareholders being paid out, but the language is sometimes used where one organisation is clearly absorbing the other rather than coming together as equals.

The Register of Mergers maintained by the Charity Commission allows certain transfers to be recorded so that future legacies left to the transferring charity can pass to the successor.

Key steps

  1. Open an honest conversation between the two boards. Before lawyers, accountants or members get involved, the chairs and senior trustees of both charities need a candid discussion about why a merger is being considered, what each side hopes to gain, and whether there is genuine alignment of mission. Many merger talks fall apart later because this groundwork was skipped or rushed.
  2. Carry out due diligence on both sides. Each charity should examine the other's finances, governing document, restricted funds, property interests, employment liabilities, contracts, pension obligations, ongoing disputes and reputational risks. Trustees have a duty to act in the best interests of their own charity, so going in blind is not an option, even where the relationship feels collaborative.
  3. Choose the legal structure for the merger. Decide whether the deal will be a transfer of assets and activities from one charity to another, the creation of a new vehicle to receive both, or a group structure with a parent and subsidiary. The right choice depends on legal form, tax position, asset complexity and what the trustees want the post-merger organisation to look like.
  4. Address constitutional and regulatory steps. Check each governing document for restrictions on transferring assets, amalgamating with another body, or amending objects. Member approval may be required, and Charity Commission consent or input may be needed for certain steps. Notify other regulators where relevant, for example HMRC for charitable tax status and the FCA for registered societies.
  5. Complete the transfer and register the merger. Execute the transfer agreement, move assets and staff (TUPE may apply), novate or assign contracts, close bank accounts in the right order, and wind up the transferring charity. Consider entering the merger on the Charity Commission's Register of Mergers so that future legacies left to the old charity can pass to the successor.

Common questions

Q What is the difference between a merger and collaborative working?
A merger combines two or more charities into a single ongoing entity, with one or more of the original organisations being wound up. Collaborative working covers looser arrangements, joint projects, shared back-office functions, secondments, joint ventures or partnership agreements, where each charity keeps its separate legal identity and governance. Collaboration is often a sensible first step that can either remain permanent or evolve into a full merger later if the relationship works.
Q Do trustees need Charity Commission approval to merge?
It depends on the route taken and the governing documents involved. Some mergers can be carried out using existing powers in the trustees' governing document, while others require a scheme, a constitutional amendment, or specific Commission consent, for example where permanent endowment is involved or where the charity is unincorporated and lacks a power to transfer assets. Trustees should check their constitution carefully and seek guidance before assuming consent is unnecessary.
Q What is the Register of Mergers and why does it matter?
The Register of Mergers is a public record maintained by the Charity Commission under the Charities Act. Recording a merger on the register means that gifts left in wills to the transferring charity can generally take effect as gifts to the successor charity, even after the original body has ceased to exist. This matters because legacy income is often substantial and donors may not update their wills after a merger.
Q What happens to restricted funds when charities merge?
Restricted funds remain restricted. If one charity holds funds tied to a particular purpose by the donor or by its objects, those restrictions follow the money into the successor charity, which must continue to apply them for the original purpose. This can shape the structure of the merger, particularly where permanent endowment or specific trust property is involved, and may require Commission input to handle properly.
Q Are staff protected when charities merge?
In most charity mergers the Transfer of Undertakings (Protection of Employment) Regulations 2006, known as TUPE, will apply to the staff moving across. This generally means employees transfer on their existing terms and continuity of service is preserved. Trustees on both sides should plan early consultation, take employment advice and budget for any redundancy or restructuring costs that may arise after completion.
Q Can two charities with slightly different objects merge?
Often yes, but the objects question is central. Trustees of each charity can only transfer assets to a body whose purposes are sufficiently similar, and the successor charity must be willing and able to apply those assets for the original purposes. Where objects are close but not identical, the governing document of the receiving charity may need amending, or a scheme may be required to align things properly.
Q How long does a charity merger usually take?
Realistically, most mergers take somewhere between six and eighteen months from initial board agreement to legal completion, and integration of operations continues well beyond that. The timeline depends on the legal forms involved, the complexity of assets and contracts, whether member or regulator consent is needed, and how much due diligence throws up. Rushing the process is one of the most common reasons mergers struggle in the years that follow.
