Trustee indemnity insurance cost: what actually drives the premium
Why nobody can honestly quote you a figure in an article
Trustee indemnity insurance (TII) protects trustees personally against claims arising from their decisions and conduct in running the charity — and, depending on the wording, protects the charity where it indemnifies them. Insurers price that promise on the specific organisation in front of them. Two charities with identical incomes can carry very different premiums because one runs a helpline staffed by volunteers and the other runs residential care for vulnerable adults. Any article quoting “typical premiums” without knowing your charity is guessing. What an article can do is show you the pricing machine, which is the same everywhere.
The drivers, in rough order of weight
1. The limit of indemnity
The single most direct lever. TII is usually bought with limits from the low hundreds of thousands up to several million pounds, and premium scales with the limit — though not linearly: doubling the limit rarely doubles the premium, because most claims resolve well below the top of the cover. Choosing the limit is a judgement about worst plausible cases, and it is where advice earns its keep.
2. Income and assets
Income is the standard proxy for scale: more activity, more decisions, more people affected, more scope for dispute. Assets — property, investments, reserves — matter too, because managing them is itself a trustee duty that can be got wrong.
3. What the charity actually does
Activity is where underwriters spend their attention. Work with children or vulnerable adults raises safeguarding exposure and will be underwritten carefully, with wordings differing on how they treat it. Overseas operations, campaigning, regulated activities, grant-making at scale and trading subsidiaries each add their own questions. A village hall committee and an international aid charity are simply different risks wearing the same product name.
4. Claims, complaints and governance
Past claims or regulatory involvement move premiums the way they do everywhere in insurance. So, in the other direction, does demonstrable governance: current policies, financial controls, trustee recruitment and training, safeguarding procedures. Charities that can evidence how they run themselves present better and, over time, price better.
Packaged vs standalone: how it’s actually bought
Most small charities meet TII as an optional section of a charity combined policy — the package that also carries public liability, employers’ liability, property, and often money and personal accident covers. Buying it that way is administratively simple and usually economical, and for straightforward charities it is often the right answer. Standalone trustee indemnity or charity D&O policies come into their own for larger organisations wanting higher limits, entity cover, or employment practices cover — the trade-off is a second policy to manage and a second renewal to get right. Our trustee indemnity insurance for charities page covers the cover itself in detail, and the differences from charity D&O are worth understanding before comparing quotes.
Which UK business covers are compulsory, and on what authority
Trustee indemnity insurance is not compulsory for a charity; the table below sets out which UK business covers are, and on what authority.
| Cover | Compulsory in the UK? | Statutory minimum | Authority |
|---|---|---|---|
| Employers' liability | Yes, for most employers | £5m for any one occurrence, including costs and expenses | Employers' Liability (Compulsory Insurance) Regulations 1998, reg 3 |
| Professional indemnity | Not by general statute, but mandatory under several regulators | Set by the regulator — for example £2m or £3m under the SRA Minimum Terms, £250,000 under ARB guidance | SRA Minimum Terms and Conditions; ARB PII Guidance |
| Public liability | Not compulsory as a matter of general law | None | No general statutory requirement |
| Directors and officers | Not compulsory | None | Companies Act 2006 s.233 permits a company to purchase and maintain insurance for a director |
| Cyber | Not compulsory | None | No general statutory requirement |

Why quotes vary — and what to compare besides price
When quotes for the same charity differ, the explanation is usually in the wording, not the arithmetic: who counts as an insured person (trustees only, or employees and volunteers in management roles); how defence costs are handled; what the safeguarding, pension and trading exclusions actually say; whether the charity entity itself has any cover. A cheaper quote answering a narrower question is not a saving. Put limit, wording and exclusions on the table alongside price — that comparison is the substance of what a broker does with a TII placement, however small.
The honest bottom line for small charities
For most small charities, trustee indemnity cover is typically modest in cost relative to the risk it removes — personal claims against volunteers who took on the role in good faith. That is a qualitative statement, deliberately: the precise figure depends on everything above. The practical route to it is a short conversation and a copy of your accounts, after which a real number replaces the guesswork.
Frequently asked questions
How much does trustee indemnity insurance cost for a small charity?
There is no single figure, because premiums are priced on the charity's income, activities, assets and claims record and on the limit chosen. What can be said honestly is that for most small charities, trustee indemnity cover is typically modest in cost relative to the personal exposure it protects trustees against — which is why insurers and umbrella bodies generally regard it as a routine purchase rather than a luxury.
What actually drives the premium?
The main drivers are the limit of indemnity chosen, the charity's income and assets, what it does — especially regulated activities, work with children or vulnerable adults, overseas operations or trading subsidiaries — the number of trustees and staff, the claims and complaints history, and the quality of governance and financial controls.
Is trustee indemnity insurance sold on its own or as part of a package?
Both. Many small charities buy it as a section of a charity combined policy alongside public liability, employers' liability, property and other covers — often the most economical route. Standalone trustee indemnity (or charity D&O) policies are more common for larger charities that want higher limits or broader management liability cover.
Why do quotes for the same charity vary so much?
Because insurers weight the drivers differently and their wordings differ — what counts as an insured person, how defence costs are treated, what exclusions apply to safeguarding, pension or trading exposures. A cheaper quote may simply be answering a narrower question. Comparing limit, wording and exclusions alongside price is exactly the work a broker does.
Can a charity pay for trustee indemnity insurance from its own funds?
Generally yes. Charity law treats trustee indemnity insurance as a permitted use of charity funds in most circumstances, subject to the charity's governing document — some older governing documents restrict it, in which case the position should be checked before buying. The policy protects trustees personally, which is why governing documents occasionally address it.
