Navigating Charity Mergers and Collaborations: When and How to Do It Right

In today’s economic and social climate, many charities and not-for-profits are facing the same challenge: how to keep delivering meaningful impact with fewer resources. For some, collaboration or even merging with another organisation is no longer a distant idea, it’s a necessary step towards sustainability, efficiency, and long-term success.
But how do you know when collaboration makes sense, and how can you do it without losing your charity’s mission, culture, or credibility?
At Third Sector Experts International, we’ve guided numerous organisations through this process, from informal partnerships to full legal mergers, and we’ve seen what works (and what doesn’t).

Why More Charities Are Collaborating
Rising costs, tighter funding, and increasing regulatory scrutiny mean that duplication of effort is no longer sustainable. Whether you’re a UK-registered charity working locally or one operating internationally, collaboration can help you:
Achieve economies of scale, sharing staff, premises, or systems.
Increase reach and impact, particularly in overseas programmes where partnerships with local NGOs or other UK charities are key.
Strengthen credibility, funders are increasingly drawn to organisations that can demonstrate partnership working and value for money.
Access new funding opportunities, some grant makers now favour collaborative bids over standalone applications.
That said, collaboration isn’t always the answer. For some organisations, the right step is closer alignment, like sharing back-office functions or co-delivering projects, rather than a full merger.
Understanding the Options
Not all partnerships are the same. Here are the most common models used by charities in the UK and internationally:
1. Informal collaboration
A short-term, flexible agreement to work together on a specific project. This often doesn’t involve any legal change but should still be backed by a Memorandum of Understanding (MoU) to set out roles, responsibilities, and expectations.
2. Strategic alliance
A more formal partnership where two or more charities agree to share certain functions (like HR, fundraising, or governance training) to reduce duplication.
3. Joint venture
A separate legal entity (often a CIC or limited company) created to deliver a joint project, sometimes between a charity and a corporate or international NGO.
4. Full merger
Two or more organisations come together legally under one governing document, board, and name. In England and Wales, this involves notifying the Charity Commission and potentially transferring assets under the Charities Act 2011.
Each approach has its benefits, and risks, depending on your size, mission, and funding structure.
When a Merger or Collaboration Makes Sense
A merger should never be driven by panic or pressure alone. Here are some indicators that collaboration or merger may be worth exploring:
Your funding streams overlap significantly with another organisation’s.
You’re competing for the same beneficiaries or grants, creating duplication.
You’ve struggled to recruit or retain trustees or key staff.
There’s a strategic fit, similar mission, culture, and values.
You want to expand internationally but need partners with local infrastructure.
Conversely, if the partnership would dilute your mission, weaken governance, or create cultural friction, it may be better to pursue an alliance rather than a merger.
Steps to a Successful Charity Merger
A well-managed merger can strengthen your charity’s future. A poorly managed one can damage morale, finances, and public trust. Here’s a structured approach that works:
1. Define the strategic purpose
Why merge? Cost-saving, impact, reach, or governance reform? All trustees should agree on the purpose and expected outcomes before approaching another organisation.
2. Due diligence
Review the partner’s finances, governance, assets, liabilities, safeguarding, and reputation. International operations need particular scrutiny; foreign bank accounts, contracts, or partnerships can carry compliance risks.
3. Stakeholder engagement
Bring key staff, volunteers, funders, and beneficiaries into the conversation early. Transparency builds trust and reduces resistance.
4. Legal and governance process
Depending on your structure, you may need to:
Draft a new governing document or amend existing ones
Notify the Charity Commission
Transfer assets and liabilities
Register the change with Companies House (for CIOs or charitable companies)
5. Cultural alignment
Many mergers fail not for legal or financial reasons, but because of conflicting values or leadership styles. Invest time in joint strategy days, trustee workshops, and shared vision building.
6. Integration and communication
Post-merger, you’ll need a communication plan for stakeholders, a clear organisational chart, and aligned policies (safeguarding, HR, finance). Consistency is key.
The Common Pitfalls (and How to Avoid Them)
Rushing the process, merging too fast without a strategic rationale.
Underestimating complexity, especially where international projects are involved.
Ignoring culture and leadership differences.
Failing to communicate clearly with funders or the public.
Skipping professional advice, governance, legal, and financial guidance are essential.
Mergers are often compared to marriages: successful when based on shared purpose, trust, and communication, not desperation or convenience.
International Operations: Added Considerations
For UK-registered charities delivering projects abroad, collaboration introduces further layers of complexity:
Compliance in multiple jurisdictions, ensure partners overseas meet charity law standards.
Due diligence on local delivery partners, including safeguarding and anti-bribery measures.
Cross-border governance, clarity on who has oversight and accountability.
Foreign funding rules, some countries restrict international transfers or impose reporting obligations.
Getting this right protects both your beneficiaries and your organisation’s reputation.
