Town planning consultants
Landowners, developers and investors act on what you tell them about a site’s planning prospects — they buy land, sign option or promotion agreements, or commit development finance on the strength of your advice. When that advice is later alleged to have been negligent, and the loss is measured against the land rather than your fee, professional indemnity insurance is what answers the claim and funds your defence.
Part of: Professional indemnity for consultants
In short
A town planning consultant needs professional indemnity insurance because clients make substantial land and investment decisions on the strength of your advice — and if your view of a site’s planning prospects, a planning application or an appeal is later alleged to be negligent, you can be pursued for a loss that dwarfs the fee you earned. Professional indemnity responds to your legal liability for negligent advice, errors and omissions in your professional work and, just as importantly, pays the cost of defending you, which is incurred even where an allegation ultimately fails. The standard you are held to is reasonable skill and care — the competence of a reasonably skilled planning professional — not a promise that a particular permission will be granted, because the decision rests with the local planning authority or an inspector, not with you. Cover is written on a claims-made basis, so the policy that responds is the one in force when a claim is made or a circumstance notified, which is why the retroactive date and run-off cover matter; and because there is no statutory minimum limit for planning consultants, the limit is driven by your contracts, the reliance placed on your advice and the value of the sites and schemes you advise on.
Town planning consultancy is advisory work, and its risk flows from one fact: other people commit money on the strength of what you advise. A landowner decides whether to promote a site, a developer decides whether to buy it, and a funder decides whether to back a scheme — each relying on your judgement of what planning permission can be achieved, and on what terms. When that advice is later alleged to have been wrong, and a loss follows, you can be held responsible. Professional indemnity insurance responds to your legal liability for negligent advice, an error or an omission in your professional work, and pays the cost of defending the allegation.
Defence costs matter as much as damages: even a claim that is eventually withdrawn must be investigated and answered, and that is what the policy funds. The table sets out claims typical of planning consultancy and how cover responds.
| Typical claim against a planning consultant | How professional indemnity responds |
|---|---|
| Advice that a site had development potential, or that permission was achievable, proved wrong and a client bought land or committed finance in reliance on it | Defends you and meets your liability for the loss flowing from the negligent advice, where that reliance was within your engagement |
| A statutory appeal deadline, consultation window or submission date was missed, costing a client a decision or a right of appeal | Responds to the allegation that a deadline within your remit was not met |
| A planning application or appeal was poorly prepared and refused or dismissed where competent handling would have changed the outcome | Responds where negligent preparation or strategy caused the client’s loss |
| Negligent advice on planning conditions, the Community Infrastructure Levy or a Section 106 obligation left a client with an unexpected liability or a scheme that could not proceed as planned | Meets your liability for the negligent advice on which the client acted |
| A technical input you led on or coordinated was inadequate and the planning decision or the scheme suffered as a result | Responds to your liability for a failure to exercise reasonable skill and care in work within your scope |
Across all of these the claim is about how you carried out your professional work — not injury to a person or damage to property, which is why public liability does not answer it, and why an oversight as ordinary as a missed date or a misjudged prospect can still be costly.
The exposure that defines planning consultancy is the gap between your fee and the cost of getting the advice wrong. Planning advice is rarely an end in itself — it is the basis on which someone makes a far larger decision about land.
Because those losses track the value of the land and the abortive development costs, not the fee that earned them, a single planning claim can be many times the size of the engagement behind it. That is what makes planning advice a high-limit risk, and why the parties who can bring a claim matter. Where you grant others the right to rely on your advice — through a reliance letter to a funder or purchaser, or by advising a party to a joint venture — each party entitled to rely is a party who can claim, so reliance should be a deliberate decision rather than a default.
Alongside the large reliance claims sit the operational errors that make up much of a planning consultant’s day-to-day exposure. These are the ones most within your control — and most capable of costing a client a decision they cannot get back.
In each case the claim is not that the authority reached a particular decision, but that you failed to do competently the part that was yours — and it is that failure, not the outcome itself, to which professional indemnity responds.
You are not expected to warrant a result. A planning decision is ultimately the local planning authority’s or, on appeal, an inspector’s — not yours — and the law reflects that. The standard you are held to is reasonable skill and care: the competence of a reasonably skilled planning professional, judged on what was reasonable at the time and not with hindsight once the decision is known. A refusal is not, in itself, negligence; a claim succeeds only where you fell below that standard and the client lost as a result. Clear scope and stated assumptions are your best protection:
Professional indemnity is written on a claims-made basis: the policy that responds is the one in force when a claim is made against you, or a circumstance is notified — not the one you held when you did the work. Two features follow, and for planning work they are decisive:
When you place or renew cover, the Insurance Act 2015 requires a fair presentation of the risk, so disclose your work, the reliance you grant and any claims or circumstances fully and accurately — an accurate presentation is what makes the cover dependable when a claim arrives. There is no statutory minimum limit for a planning consultant, so the figure is driven by your contracts, the reliance placed on your advice and the value of the sites and schemes you work on. As a matter of professional standing, the Royal Town Planning Institute expects chartered members in practice to carry professional indemnity, and many client and framework appointments require it before you can be engaged. Because a single claim can be far larger than any fee, a specialist broker can help you weigh the limit against the exposure rather than the premium alone.

We would rather say so than waste your time. We are probably not for you if:
There is no statutory requirement to hold it, and no law sets a minimum limit for planning consultancy. In practice it is close to essential: the Royal Town Planning Institute expects chartered members in practice to carry it, and client, funder and framework appointments almost always require it before you can be engaged. It also protects your own finances if your advice is later challenged.
Because you are judged on your work, not on the decision. You are not expected to warrant that permission will be granted; you are expected to exercise reasonable skill and care in the advice you give and in the application or appeal you run. If you fell below that standard — a negligent appraisal of the prospects, a missed deadline, a poorly prepared case — and the client lost as a result, the claim is yours to answer whatever the authority decided.
They respond to different things. Professional indemnity covers financial loss a client or a relying party suffers because of your advice or professional work, such as negligent advice on a site’s planning prospects. Public liability covers injury to people or damage to property caused by your activities, for example during a site visit. Planning consultancy’s defining risk is advisory, so professional indemnity is the cover that answers it, and many firms carry both.
Your client can rely on it, and so can anyone to whom you grant reliance — a funder or purchaser named in a reliance letter, or a party you advise in an option, promotion or joint-venture arrangement. It matters because each party entitled to rely is a party who can bring a claim, so reliance widens your exposure. Granting it deliberately, and telling your insurer about it, keeps the risk one you have allowed for.
There is no statutory minimum, so the limit is driven by your contracts and the reliance placed on your advice. A useful guide is the value of the land and schemes you advise on, because a claim is measured against that value and the abortive costs, not the fee you earned — so a single claim can be far larger than the work that caused it. For that reason limits for reliance-heavy planning work are often set high, and a specialist broker can help you judge it.
Claims-made means the policy that responds is the one in force when a claim is made against you, or a circumstance notified — not the one you held when you did the work. So the retroactive date must reach back to your earliest relevant advice, and run-off matters when you retire, sell or stop trading, because planning claims can surface years later when a site is finally promoted, developed or sold.
It covers your liability where the loss flows from your negligence — a statutory deadline missed within your remit, or an application or appeal so poorly handled that a competent adviser would have changed the outcome — together with the cost of defending the allegation. It does not turn a lawful refusal into a payout: if you advised competently and the authority simply decided against the scheme, there is no negligence for the policy to answer.
