Independent oversight for charity investment portfolios

Help your charity’s capital work as hard as its mission.

Millenne Advisors works with UK charities holding £1m–£20m in long-term assets. We support two common situations: when you are investing for the first time and need a clear Investment Policy Statement and CAIF allocation framework, and when you have already invested but results have not met expectations and trustees want an independent second opinion.

Who we help

We specialise in helping charity boards and trustees who oversee long-term investment portfolios and want clarity on how best to use CAIFs and other charity funds.

Starting to invest

Never invested & no IPS

Charities with growing reserves or newly received capital that has not yet been invested, and where there is no formal Investment Policy Statement to guide decisions or CAIF selection.

First-time investing No IPS yet Need CAIF framework
Already invested

Invested, but not as expected

Charities that already hold CAIFs or other charity funds but have seen disappointing results: capital erosion, volatility or persistent underperformance versus reasonable benchmarks.

Assets have fallen Performance concerns Preparing for review
Trustee boards

High responsibility, limited time

Boards and finance committees who are legally responsible for investment decisions, want to act prudently, and need concise, jargon-free analysis they can rely on when setting or reviewing their investment arrangements.

Governance support Plain-English reporting Independent oversight

What we do

We do not manufacture products or run a platform. We sit alongside you as an independent partner, helping you decide if, how and where CAIFs and other charity funds should fit within your long-term portfolio.

Service 1

Investment Policy & First-Time Allocation

For charities that have never invested before, we help you design a clear, board-approved Investment Policy Statement and a sensible long-term asset mix, including how CAIFs might be used, so your first step into investing is structured and aligned with your mission and risk tolerance.

Service 2

Portfolio Health Check & Manager Review

For charities that already invest, we analyse performance, risk, asset mix and fees, focusing on your use of CAIFs and other charity funds. We then provide an independent view on whether issues lie with markets, allocation or managers – and outline pragmatic options.

Ongoing Oversight & Trustee Support

For boards that want a steady, independent voice alongside them, we provide periodic reviews, trustee education and input during manager beauty-parades or re-tenders, whether you are establishing a first CAIF-based structure or refining an existing line-up.

Why focus on CAIFs?

Charity Authorised Investment Funds (CAIFs) are designed specifically for charities, but that does not make every CAIF automatically suitable. We help you understand where they fit – and where they may not.

Designed for charities

Understanding the CAIF landscape

CAIFs can offer governance, diversification and operational simplicity for charities that do not wish to build bespoke segregated portfolios. The challenge is choosing the right mix of CAIFs and ensuring they genuinely support your objectives, risk appetite and spending rules.

Our work focuses on:

  • How CAIFs sit within your overall policy and risk budget
  • Comparing CAIFs and other charity funds for your needs
  • Ensuring monitoring and reporting are trustee-friendly
Charity-specific focus We work only with charities and similar organisations, not private individuals, so our analysis is tailored to charity law, governance and practical realities.
Product-agnostic We do not manufacture funds or run a platform. Our role is to help you judge whether your current CAIFs and charity funds remain appropriate.
Pragmatic recommendations We are outcome-focused: small, practical changes that trustees can realistically implement and monitor.
Board-ready reporting Clear, concise written reports and presentations that support trustee decision-making and minutes.

How we work with you

A simple, structured process designed to give trustees clarity and confidence, without adding unnecessary administrative burden.

1. Introductory call

A short call with one or two trustees or senior staff to understand your charity, the size and role of your investment portfolio, and whether you are starting to invest or reviewing existing CAIF holdings.

2. Information gathering

We review your latest valuations, manager reports, IPS (if any), spending rules and CAIF holdings. Where needed, we agree a simple data request with your existing managers or platform.

3. Analysis & report

We analyse performance, risk, allocation, CAIF usage and costs against your objectives and constraints, then produce a clear report with traffic-light findings and practical options for the board.

4. Board discussion

We present our findings, answer questions and help you agree next steps – whether that is refining your IPS, adjusting CAIF allocations or running a structured re-tender.

Example outcome

From unease to a clear plan

A charity with a £7m long-term fund invested mainly in two CAIFs had seen little real growth. Our review identified:

  • Concentration in a single manager’s approach
  • Asset mix that was more cautious than intended
  • Fees at the upper end of typical ranges

We helped trustees refine their IPS, diversify across complementary CAIFs and improve monitoring, giving the board greater confidence in its oversight role.

Clear scope & fixed fees.
For most charities in the £1m–£20m range we offer the Portfolio Health Check on a fixed-fee basis agreed in advance, so you always know the cost before you commit.
