Choosing a UK board evaluation provider means checking four things: independence from the company, including any audit, search or consultancy relationship; alignment with the Chartered Governance Institute's Code of Practice for board reviewers; genuine experience in your sector; and a fee structure the chair can defend in the annual report.
This guide is for chairs and company secretaries comparing board evaluation services after the decision to go external has been taken. If that decision is still open, start with our comparison of internal and external board effectiveness reviews.
A disclosure before the detail. BoardServe writes this guide and sells governance software that includes effectiveness reviews. It reflects our own research into what UK providers publish on their own sites, checked on the dates shown. It is not independent, and the providers named below are market context, not a ranking.
One point of vocabulary. The market sells "board evaluation". The FRC's 2024 UK Corporate Governance Code says board performance review throughout. Same exercise, but the Code's wording is the one your annual report should use.
What the board needs to decide before you approach a provider
Settle these five points in a short paper before the first supplier call. They shape the brief, the shortlist and the fee.
- What independence means in practice. Provision 21 of the UK Corporate Governance Code 2024 requires the external reviewer to be identified in the annual report, with a statement about any other connection it has with the company or individual directors. If your preferred firm also does your audit, your executive search or your remuneration benchmarking, that connection gets written down and read by investors.
- Which lenses are in scope. Provision 21 covers the board, its committees, the chair and individual directors. Cheaper quotes often cover the board as a whole and nothing else; individual director appraisal and a committee-by-committee view are dropped most often.
- Sector experience, defined concretely. "Experience of charities" is not the same as having reviewed a charity of your income band and regulatory profile. Ask for two comparable engagements, not a client logo wall.
- Fee model. Fixed fee against a defined scope, or a day rate against an estimate. Day rates are open-ended; fixed fees need a tight scope document to mean anything.
- Timing. Provision 22 expects the chair to act on the results, and Provision 23 expects the annual report to describe how the review was conducted. Both are easier when fieldwork finishes months before the report is drafted, not weeks.
Who provides board evaluation services in the UK?
Four kinds of provider serve this market: professional-services and audit firms with governance practices; independent specialist evaluators; sector and membership bodies offering reviews to their own members; and governance platforms that supply the instrument, the evidence trail and the reporting. The Chartered Governance Institute accredits reviewers across these groups and publishes a directory of accredited suppliers.
Professional-services firms. Governance practices inside audit and advisory firms pair qualitative interviews with quantitative diagnostics. Grant Thornton describes itself as "an accredited board reviewer" and states that it mitigates conflicts of interest arising in its processes (Grant Thornton, checked 3 August 2026). BDO states that it reviews "large corporates, including listed business, AIM listed entities, government bodies and not-for profit organisations", and that in financial services it sits on the FCA and PRA Skilled Person Panel (BDO, checked 3 August 2026). Neither publishes a fee.
Independent specialist evaluators. Firms whose only product is board review. Board Excellence describes itself as "a leading provider of external board evaluations and reviews in Ireland, the UK and over 35 countries internationally", says its evaluation programme has been accredited by the Chartered Governance Institute, and includes 12 months of follow-on support to the chair, secretary and chief executive at no additional cost (Board Excellence, checked 3 August 2026).
Sector and membership bodies. Umbrella bodies run reviews for their members at a published day rate, with the sector knowledge already in place. Natspec, the association for specialist further education colleges, charges members £675 a day excluding VAT, plus travel and accommodation where required, payable once the report is delivered (Natspec, checked 3 August 2026). If you belong to a sector body, check what it offers before running an open tender.
Governance platforms. Software that runs the instrument, collects responses, produces the analysis and holds the evidence, whether the round is facilitated internally or externally. BoardServe sits here: board, committee, chair and individual director reviews on one platform, findings carried into an action plan tracked between cycles, AI-assisted analytics and board-ready Word reports, and a time-stamped record of every response and request, licensed at organisation level. A platform is what the facilitator and the company secretary work in; where Provision 21 expects an external facilitator, it sits alongside one.
What does the Chartered Governance Institute's Code of Practice for board reviewers check?
The Code of Practice for board reviewers, published on 21 July 2023 by the Chartered Governance Institute with an independent working group that included the Financial Reporting Council, sets expectations for reviewers on quality and value for money. Accreditation against it assesses experience, professional qualifications, references from board chairs, sample redacted reviews and continuing professional development plans.
The Institute states that adherence to the Code "will give assurance about the quality and value for money of a service provider to those commissioning external board review services, as well as to investors and other stakeholders" (CGI, 21 July 2023, checked 3 August 2026). A separate version covers not-for-profit organisations: charitable, educational and sports bodies. For charities, the Charity Governance Code sets the parallel expectation of periodic external review, and that not-for-profit version is the benchmark to apply.
Accredited providers are listed in the Institute's Directory of Accredited Board Performance Reviewers (checked 3 August 2026). The Code is voluntary and the directory is not exhaustive, so absence from it is not evidence of poor quality. Its value is that it turns "are they any good" into a question with a documented answer: where a provider is not accredited, ask how they meet the Code and record the answer in the selection paper.
What does an external board performance review cost in the UK?
Few UK providers publish a price. The figures that are published start at around £5,000 for a fixed-fee external review, with sector-body day rates of £675 at the lower end. Governance360 cites £3,000 to £10,000 as the typical cost for a smaller charity. Larger listed and multi-entity engagements are quoted after a scoping conversation.
| Source | Published figure | Model | Checked |
|---|---|---|---|
| Merchantec Capital | "typically starting from £5,000" | Fixed fee against a defined scope | 3 August 2026 |
| Natspec (members only) | £675 a day excluding VAT, plus travel and accommodation | Day rate, payable on delivery of the report | 3 August 2026 |
| Governance360 (comment on the market, not its own fee) | £3,000 to £10,000 | Described as not viable for a charity with income of £500,000 to £2 million | 3 August 2026 |
| Grant Thornton | None published | Quoted on scope | 3 August 2026 |
| BDO | None published | Quoted on scope | 3 August 2026 |
| Board Excellence | None published; 12 months of follow-on support included | Quoted on scope | 3 August 2026 |
Read that table with two cautions. Published figures are entry points for a defined scope, and scope is where the money is: interviews with every director, observing a board meeting and a committee-by-committee view all add days. And since most of this market quotes rather than publishes, three quotes priced against one written scope tell you more than any published range.
A selection checklist for the board paper
Score each shortlisted provider against these seven criteria, one column per firm. The right-hand column is the evidence you will want on file when the annual report is drafted.
| Criterion | What to ask for | Evidence to keep |
|---|---|---|
| Independence and connections | Every current and recent commercial relationship with the company, its directors and its group | The written disclosure supporting the Provision 21 statement |
| Code of Practice alignment | Accreditation status, or a written explanation of how the reviewer meets the Code | Directory entry or the reviewer's dated response |
| Sector and size experience | Two comparable engagements by sector and size, with a chair reference | Reference notes and a redacted sample review |
| Scope against Provision 21 | Confirmation that board, committees, chair and individual directors are covered, or a note of what is not | The signed scope document |
| Fee model | Fixed fee or day rate, what triggers additional cost, whether follow-up is included | The quote, priced against your written scope |
| Reporting route | What reaches the full board, the chair alone, and the annual report description | Draft report structure agreed in advance |
| Action tracking | How recommendations are recorded, owned and monitored until the next review | The action plan format, and who maintains it |
The last row is the one most often left out of the brief, and it is the one Provision 22 depends on: the chair is expected to act on the results. A report with no owner and no tracking is harder to evidence a year later.
Common mistakes when appointing a board reviewer
Comparing quotes that price different work. Three quotes at £6,000, £14,000 and £27,000 usually describe three different engagements. Issue one written scope first.
Treating the Code of Practice check as optional. It costs one question and one email, and it converts a subjective judgement about quality into a documented one. Skipping it becomes visible later, when someone asks how the reviewer was selected.
Leaving the reporting route undefined. Directors answer candidly when they know who sees what. Agree before fieldwork starts what goes to the full board, what goes to the chair alone, what the senior independent director receives about the chair, and what the annual report will say.
Asking the conflicts question last. The Provision 21 disclosure is written months after the reviewer is appointed, by which point the relationship is difficult to unwind. Put it in writing at shortlist stage.
Buying a report rather than a cycle. The 2024 Code frames this as a continual process of improvement, not a triennial document. If nothing survives delivery of the report, the next review starts from the same place. Our guide to running the annual review covers the cycle once a provider is appointed, and our overview of board effectiveness frameworks sets out how the main methodologies differ.
Next step
If your shortlist includes running the review on a platform rather than as a standalone consultancy engagement, our board effectiveness reviews page sets out what BoardServe covers against the criteria above: the four Provision 21 lenses, internal or externally facilitated rounds, the evidence trail, and action tracking between cycles. It suits organisations that want the instrument, the evidence and the follow-through in one place, alongside an external facilitator where the Code expects one.
