How Charities Actually Build Legacy Programs

If you were handed the job of building a fundraising program where every relationship you started this year would only pay off in ten to forty years, where none of your work would show up on this quarter's revenue report, and where the metrics your board understood were more or less useless for judging whether you were succeeding — you would understand, roughly, the job that legacy fundraising officers do inside the world's most effective charities.

The strange, patient, high-return-but-slow-clock economics of that role are what this piece is about. It is written for anyone who wants to understand what actually happens inside a charity when they build a program like this — whether you are considering leaving a gift, are working inside a nonprofit thinking about starting one, or are simply curious about how a category that quietly funds hospices, hospitals, universities, and research foundations actually works from the inside.

The Money Behind the Curtain

Start with the numbers, because they are more striking than most people realise.

The British Heart Foundation reported £108.4 million from legacies in its most recent financial year — the highest figure in its history. Cancer Research UK has historically topped the UK legacy giving table with income around £177 million in some years. Between them, about eight large health charities account for roughly half of all legacy giving in the UK health sector.

For a mid-sized charity — the kind most of us have actually heard of but don't necessarily support ourselves — legacy income typically settles at around one-third of voluntary income. For smaller charities that have built the program deliberately, it can reach 40% or more. For charities that never invest in it, the number is often close to zero, and their long-term financial position looks very different as a result.

That gap — between charities that treat legacy giving as a core strategic function and those that treat it as an afterthought — is one of the widest and most consequential in the entire nonprofit sector. The rest of this piece is about how the first group actually gets there.

What a Legacy Team Actually Does

If you walked into the legacy office at a mature program — the BHF has forty-plus people working on this, mid-sized charities typically have two to five — you would see something that does not look much like the frantic energy of most fundraising departments.

The pace is slow. The desks are covered with donor files rather than campaign briefs. The wall calendar is planning eighteen months out, not eighteen days out. And the conversations are almost never about "closing" — they are about listening, remembering, and staying in touch with people the team has known, in some cases, for two decades.

The core operational tasks look roughly like this.

Identifying legacy prospects. This is not a wealth-screening exercise. It is a loyalty screening exercise. The strongest predictor that someone will leave a gift in their will is not their income — it is how long they have been supporting the charity. A donor who has given £30 a year for fifteen years is a much stronger prospect than a donor who gave £500 once last month. Teams build their prospect lists from long-term giving records, event attendance, and existing volunteer relationships.

Running the gentle communication programme. Newsletters, letters, invitations to hear about long-term work, occasional lunches or teas. The rhythm is measured — usually four to six touchpoints a year — and the tone is never solicitous. The goal is to keep the relationship warm, keep the charity top of mind, and gently make clear that this is a way to give if the supporter ever wants to.

Confirming and stewarding pledgers. When a supporter tells the charity they have included them in their will (roughly half of legacy donors do this; the other half prefer to remain private), the team welcomes them into the Legacy Society — a named recognition group with its own events and communications. From that point on the work becomes less about persuasion and more about relationship maintenance across years.

Managing the estate administration side. When a donor passes and the estate begins probate, someone on the team handles the legal correspondence with executors and solicitors, tracks the eventual receipt of the gift, and — crucially — writes the personal thank-you letter to the family that most executors describe as one of the most meaningful parts of the whole process.

The broader donor-facing walk-through of what all of this looks like from the supporter's perspective is covered in the guide to how legacy fundraising actually works. This piece is about the inside view.

The Economics That Make It Work

The financial case for building a legacy program is unusual, because it violates almost every rule of ordinary fundraising economics.

Ordinary fundraising: you invest in a campaign this year, you measure the return this year, you decide next year based on this year's data. Time horizon from investment to result: months.

Legacy fundraising: you invest in a programme this year, you build relationships across the next five to fifteen years, you receive gifts starting seven to twenty years after that. Time horizon from investment to first meaningful return: often a decade.

The reason charities do it anyway is that once a legacy programme is mature, the ROI is exceptional. Industry data consistently suggests that for every pound or dollar invested in a well-run legacy programme, the return over five to ten years runs to fifteen to thirty times that investment. These are numbers no other fundraising category can match. The catch is that the payoff arrives late, and the finance director has to be patient enough to believe the model.

This is why the boards of the charities that succeed at this all tend to look similar. They have chairs and treasurers who take a long view. They tolerate zero return for the first three to five years of a programme's life. They measure success by leading indicators — the number of new pledgers confirmed, the growth of the Legacy Society, the size of the stewardship list — rather than by lagging revenue. Charities without that governance rarely make it through the early years.

The Five Phases of Programme Maturity

Legacy programmes at almost every scale go through the same phases, roughly in sequence.

Phase 1: Toe in the water (Years 1–2). The charity adds a small line to its regular newsletters mentioning that gifts in wills are welcome, uploads a simple "leave a gift in your will" page to its website, and hires one part-time person to respond to enquiries. Investment: minimal. Result: a handful of enquiries a year, mostly from supporters who had already decided to do this on their own.

Phase 2: Structured programme (Years 3–5). The charity commits to legacy fundraising as a strategic priority. A dedicated legacy fundraiser is hired. Marketing collateral is developed. A Legacy Society is launched with its own name and identity. Prospect research begins in earnest. Cost: a small percentage of expected legacy income. Visible results: still limited, but the number of confirmed pledgers begins to grow measurably.

Phase 3: Mature programme (Years 5–10). The Legacy Society has hundreds or thousands of members. The team has grown to three to five people. The first meaningful legacy gifts from the programme era start arriving. The board sees revenue against invested cost that would be embarrassing to any annual fundraising benchmark — but has taken a decade to arrive.

Phase 4: Category leader (Years 10–20). Legacy income becomes a top-three revenue source for the charity, sometimes the single largest. The team is now a specialised department with its own director. The charity is investing 3% to 6% of expected legacy income back into the programme each year to maintain and grow it.

Phase 5: Endowment thinking (Years 20+). The programme funds not just current work but long-horizon commitments — research chairs, permanent endowments, buildings, multi-decade partnerships — that no annual campaign could ever sustain. This is where the strategic transformation of the charity actually happens.

Almost every large legacy programme in the world sits somewhere between Phase 4 and Phase 5 today. Almost every charity that has ever tried and given up did so during Phase 2, when the results looked disappointing and the leadership got impatient. Understanding the shape of the curve, and staying committed to it, is most of what separates the programmes that succeed from those that don't.

What Makes a Programme Actually Work

Talk to legacy fundraisers who have built strong programmes at multiple charities, and the same five ingredients come up.

Leadership patience. Boards that will tolerate five years of investment without headline results. Executive directors who protect the legacy team from being asked to hit short-term revenue targets. Finance directors who understand the ROI curve. This is the most important single ingredient and the one most often missing.

A named face for the programme. Legacy fundraising is intensely relational work. Programmes that rotate legacy officers every eighteen months underperform badly. The best programmes have people who have been in the role for a decade or more and are known personally to hundreds of legacy pledgers.

Genuine stewardship, not marketing. The pledgers who stay pledged are the ones who feel known. Programmes that treat legacy donors as a "list to communicate to" underperform. Programmes that treat them as individuals — remembering birthdays, sending handwritten notes, inviting them to programme visits — retain their pledgers dramatically better.

Cross-functional integration. The legacy team cannot succeed in isolation. Their prospects come from the wider supporter base, so the database needs to be shared with major-donor and annual teams. Their thanks and stewardship need to align with the overall brand voice. Their communications need to fit into the wider supporter journey.

Honest data. Programmes that promise their board specific revenue numbers three years ahead consistently lose credibility when the numbers don't materialise. Programmes that report leading indicators honestly — pledgers confirmed, prospect list health, stewardship touchpoint completion — retain board confidence through the long ramp-up.

The Strategic Transformation That Actually Happens

The revenue is the visible outcome. The invisible one is more important.

A charity that has funded itself entirely through annual campaigns is, in a very real sense, running month-to-month. It can plan next quarter's work. It can plan next year's if the economy holds. It cannot plan a decade of research. It cannot make a five-year commitment to a country programme. It cannot promise a lifetime of support to a beneficiary community.

A charity with mature legacy income can. This is why the largest medical research charities in the world are almost all charities with strong legacy programmes. It is why long-established universities are able to fund research chairs that pay off over generations. It is why some hospices have been able to guarantee their communities continuous care across decades of political and economic turbulence.

The money legacy giving brings in is meaningful. But the time horizon it enables is the transformation. This is the same idea that runs through the broader conversation on the great wealth transfer and, at the extreme, through the way Ted Turner's decades-long philanthropy programme was designed to keep working long after his passing. The scale differs. The mechanism is the same.

What Smaller Charities Can Do With Limited Resources

Not every organisation can afford a forty-person legacy team. Most cannot even afford one full-time legacy officer. This does not mean legacy giving is only available to large charities — it just means the programme has to look different at smaller scale.

Practical starting points for a charity of any size:

A single web page. A clearly written "leave a gift in your will" page on the website, with sample wording donors can give to their solicitors and the charity's legal name and registration number prominently displayed. Cost: half a day of work. Result: some enquiries will begin arriving without any further investment.

One paragraph in every appeal. Not a hard ask. A gentle mention that gifts through wills are welcome, alongside the regular donation ask. This alone typically produces a small stream of enquiries.

A part-time steward. A single trusted person — a senior fundraiser, sometimes even the executive director in the smallest charities — who is responsible for responding to legacy enquiries warmly and for staying in touch with pledgers once they confirm. Time commitment: a few hours a week. Impact: significant over years.

A partnership. Many small charities partner with specialist consultancies or shared-service platforms that handle much of the operational work. These arrangements let the charity offer a professional legacy experience without building the whole in-house infrastructure.

The point is that legacy fundraising is not restricted to charities big enough to have a dedicated department. It is, at every scale, primarily about being present, patient, and worth remembering when supporters sit down to think about what they want to keep going.

The Quiet Point Most People Miss

If you take away one thing from this piece, take this: the charity that will receive the largest legacy gift you might ever make is almost certainly not a household name. It is a hospice, a small research foundation, a local school, a community-based organisation that has quietly stayed in touch with you or someone in your family for a long time.

Those small and mid-sized charities are the ones for whom legacy income is often the difference between existence and closure. Big charities will be fine either way. The small hospice down the road, the local scholarship fund, the specialist research foundation — those are the organisations where a legacy program you did not know they had is the reason they can plan the next twenty years of their work.

The donor motivations behind those gifts are almost always personal. The mechanism the charity has built to receive them is almost always invisible from the outside. Both sides matter. Both sides quietly meet, decades apart, in the moment when a supporter's will is finally read.

The measure of a mature legacy giving programme is not how much money it raises in the current fiscal year. It is how much of the charity's future work is already funded, in principle, by decisions supporters made ten and twenty years ago that neither the charity nor the supporter felt any urgency about at the time.

If you work inside a charity considering whether to build a program of this kind, the honest answer is: the time to start is now, but the results will be waiting for the people who have your job in 2036, not for you. That is exactly the point. It is also why the charities that build these programmes are structurally different from the ones that don't — and why, decades later, they end up doing structurally different work.
