Facts before narrative
Decisions begin with legal position, ownership, obligations, evidence and recoverable value rather than headline valuation or anticipated outcome.
A proportionate framework for decision-making, delegated authority, continuity, documentary discipline and responsible institutional engagement.
Decision authority and execution authority are deliberately distinguished.
The Principal retains ultimate authority over strategy, family capital and principal transactions. Material commitments are considered through a family decision process proportionate to value, duration, risk, reversibility and effect upon protected or pledged assets.
The Director of Investment and Stewardship leads proposition development, participates in decisions, receives Office reporting and may represent the Office and execute approved commitments within delegated authority.
Detailed internal approval thresholds are maintained in the Office’s delegated-authority records and are not published.
Decisions begin with legal position, ownership, obligations, evidence and recoverable value rather than headline valuation or anticipated outcome.
Pledged assets, essential family resources and continuity commitments are identified before available capital is assessed.
Material commitments are examined against repayment, reversal, recovery and downside pathways.
The authority, interests, incentives and obligations of family members and counterparties are considered before commitment.
Statements material to value, risk, ownership or repayment should be capable of documentary support.
The Office distinguishes between value in principle and value capable of realisation within the required period.
Clarity, confidentiality, alignment and professional accountability.
Material representations should be capable of documentary support. Relevant risks, conflicts and dependencies should be surfaced early rather than deferred until documentation or execution.
The Office expects commitments to be understood in terms of authority, purpose, affordability, recoverability and consequence. In return, it seeks to provide counterparties with orderly access to information reasonably required for assessment, subject to confidentiality and proportionality.
The Office values long-term institutional relationships over transactional volume and engages selectively where mandate fit, decision authority and execution responsibility are clear.
Responsibility should not depend upon one person’s uninterrupted availability.
Authority, signatory arrangements, material decisions and institutional records are maintained so that responsibility does not depend solely upon personal memory or the uninterrupted availability of one individual.
Continuity arrangements are reviewed as the Office, its capital base and its responsibilities develop.
Institutional capability should develop ahead of institutional need.
The Office is governed according to the principle that institutional capability should develop ahead of institutional need. Governance, professional appointments and supporting infrastructure are therefore established in anticipation of complexity, rather than in reaction to it.
This approach reflects the Office's preference for measured institutional development, prudent risk management and long-term stewardship over ad hoc administrative growth.
Existing family relationships provide a practical foundation for the Office's developing professional architecture.
Steven M. Windmill maintains a personal banking relationship with TSB, continuing an intergenerational family relationship with the bank established by his father.
Leonard George Windmill maintains a private-client relationship with Debenhams Ottaway in St Albans. This relationship forms part of the wider network of established professional relationships upon which the family may draw as the Office's legal and fiduciary arrangements develop.
These are personal and family relationships. They should not be interpreted as current appointments by, or endorsements of, Windmill Family Office.
Professional infrastructure will expand in proportion to responsibility, assets and complexity.
As the Office's stewardship responsibilities and asset base consolidate, the family anticipates establishing an appropriate private banking relationship to support governance, liquidity management, succession planning and long-term stewardship. Subject to the timing and scale of future liquidity events, such arrangements will be implemented as required by the complexity of the Office's activities.
The Office's governance model anticipates the future appointment of specialist banking, legal and fiduciary counterparties as the family's institutional requirements evolve.
The Office is the designated long-term stewardship framework for family assets.
Family interests and assets are progressively brought within an orderly governance, records and succession framework. Where appropriate, legal ownership may remain in personal, corporate or trust structures while governance, documentation and intergenerational purpose are coordinated through the Office.
The Office distinguishes present ownership, beneficial interest, pledged or protected assets, prospective value and assets intended for future transfer. Transfers are implemented only when legally effective and supported by appropriate tax, accounting, fiduciary and professional advice.
Transparent, cooperative and document-disciplined engagement.
The Office is committed to maintaining appropriate standards of financial integrity, transparency and lawful conduct.
It does not accept or manage third-party capital and does not provide regulated financial services to the public. It nevertheless cooperates fully with legitimate know-your-client, beneficial-ownership, source-of-wealth, source-of-funds, sanctions, tax and related due-diligence requirements raised by established banks, lenders, professional advisers and institutional counterparties.
Material financial arrangements are expected to have an identifiable purpose, documented authority, a lawful source of funds and an intelligible flow of value. The Office does not knowingly participate in arrangements intended to conceal beneficial ownership, evade sanctions, disguise the origin of funds or frustrate lawful regulatory or tax scrutiny.
Where appropriate, the Office obtains external legal, tax, accounting or specialist advice and retains records proportionate to the nature, value and risk of the matter.
Authority carries a corresponding duty of care.
The Office is committed to lawful, fair and respectful conduct, equality of opportunity, reasonable adjustment where required, and the responsible treatment of people and counterparties.
It does not tolerate unlawful discrimination, harassment, victimisation, modern slavery, forced labour or human trafficking, and expects proportionate diligence and safeguards where employment, procurement or supply-chain exposure becomes material.
Service recognised; transition supported.
The Office supports the principles of the Armed Forces Covenant: those who serve or have served, and their families, should be treated fairly and should not face disadvantage arising from Service life.
As opportunities arise, the Office will have regard to the Armed Forces community and will seek to recognise the transferable capability of suitably qualified veterans, reservists and service leavers.
The Office intends to uphold the spirit of the Armed Forces Covenant as its activities and responsibilities develop.
Confidential and personal information is handled on a need-to-know basis. Material records are retained proportionately to support governance, continuity, legal obligations and institutional accountability.
Where specialist judgement is required, the Office engages appropriately qualified legal, tax, accounting, valuation, banking and other professional advisers.
The Office distinguishes recorded fact, professional opinion, family memory, working assumption and prospective value.
