WFO / Institutional research & collaboration
Today we have extraordinary technological, financial and informational capability. WFO believes that vision, human creativity and imagination help determine what those capabilities can achieve—and that evidence, governance and stewardship turn ambition into enduring value.
A heritage of stewardship · An active Six Capitals proposition · 2025 and 2026 research editions
Purpose and heritage
Windmill Family Office is a private single-family office combining disciplined capital stewardship, institutional governance and evidence-based analysis. Its Six Capitals framework recognises the contribution of knowledge, culture and relationships alongside financial resources.
Intellectual inheritance
The family's intellectual heritage draws on a wider Bacon tradition of enquiry. Its clearest traceable maternal ancestry spans approximately four centuries. Family origins ↗
Enterprise and capital
The family traces its capital enterprise to 1891, followed by manufacturing and family stewardship arrangements in the twentieth century. Read the historical record ↗
The traditions came together through Patricia Bacon's marriage into the Windmill family in the 1950s. Steven Windmill assumed principal responsibility in January 2019; Windmill Family Office Ltd was incorporated in 2026. The Office welcomes imaginative institutional dialogue grounded in evidence and practical capability.
Why this research exists
These two editions provide searchable reference records for 100 UK trusts and foundations each, supporting informed dialogue across family offices, philanthropy, museums, arts, heritage, science and education. Explore WFO research ↗
Each foundation appears because of its place in the cited source data. Inclusion does not imply a relationship, endorsement or funding eligibility.
Six Capitals in practice
WFO welcomes substantive engagement where complementary capabilities advance institutional purpose. Its Six Capitals approach recognises that contribution may take several forms beyond funding.
Family members may consider board, trustee, committee or advisory appointments in their individual capacities. Meet WFO's leadership ↗
Speaking, panel contributions and informed discussion at academic, museum, scientific and cultural events. Professional engagement ↗
Introductions, convening and research exchange where shared interests provide a sound basis for cooperation. The Six Capitals ↗
Project assessment, shared expertise and selected financial cooperation, where purposes and responsibilities are clear. The Office ↗
Board and trustee appointments are held by family members personally, in the interests of the institutions they serve. Any organisational or financial commitment is considered separately through the applicable governance arrangements.
WFO considers discretionary grants for organisations championed by a family member, causes with a family connection, and institutions whose contribution to society reflects shared family interests. Proposals are considered by the Family Council; funds are released following Council approval and the appropriate administrative arrangements. The Office does not operate an open public grant-application programme. See Public Service & Charitable Interests.

Evidence standards
This WFO research draws upon the UKGrantmaking dataset and research programme. UKGrantmaking identifies and analyses UK grantmakers using charity-regulator data, statutory accounts, published grantmaking information and other sector sources, supported by manual verification and data cleaning. WFO has used the first 100 entries in UKGrantmaking’s combined Largest 300 Trusts and Foundations by grantmaking spend tables as the underlying reference population for these editions. WFO’s selection, presentation, comparative treatment and commentary are its own.
Each directory reproduces the first 100 entries in UKGrantmaking's combined “Largest 300 Trusts and Foundations by grantmaking spend” table for the edition stated. It is neither a ranking of all UK funding bodies nor the separate family-foundation top 100. Values are source-published grantmaking expenditure in GBP millions. Individual totals are derived from rounded source amounts and are approximate.
The original 2025 edition reports the financial period 2023–24. The 2026 edition reports 2024–25 and separately supplies its own restated 2023–24 figures. UKGrantmaking cautions that differences in methodology, data coverage, boundaries and restatements prevent straightforward comparison between historical editions. Accordingly, any 2026 change shown in this directory uses the restated comparator within the 2026 source. A restated comparator of zero is not interpreted as evidence of zero giving.
The amount spent by an institution does not itself verify identifiable grant awards, disbursements, recipients or grant outcomes. Individual award records are incompletely published and may describe commitments rather than expenditure; intermediary transfers can duplicate records. WFO has not published its proposed independent award-level Top Ten because a defensible full-coverage comparison has not yet been established.
For the precise meaning of terms such as Capital, Authority and Stewardship, consult the WFO Glossary ↗. For WFO's institutional identity and decision-making framework, see The Office and Governance.
Institutions are listed only because they appear in the cited source ranking; inclusion implies no WFO relationship, endorsement or eligibility for support. The directory is not a grant-application portal. WFO may separately consider selective family-supported grants through its Family Council.
