Energy consultants & assessors
Clients, landlords, buyers and funders act on the ratings, audits and advice you give them. When an assessment or a recommendation turns out to be wrong, the decision built on it can cost real money — and the claim lands with you.
Part of: Professional indemnity at Apex
In short
Professional indemnity (PI) insurance covers energy consultants and energy assessors against claims that a negligent assessment, a wrong rating, or flawed efficiency, carbon or investment advice caused a client — or a third party who relied on the work — a financial loss. It pays the cost of defending the allegation and any compensation awarded, whether or not the claim is justified. Because owners, landlords, buyers and funders make real decisions on the strength of your figures, a single mis-stated rating or an over-stated saving can become a claim far larger than the fee you earned. PI is normally written on a claims-made basis and governed by the Insurance Act 2015, so both the cover you hold and the way you present your firm to insurers matter. Many accreditation schemes and client contracts require it, and they — not a single statutory figure — set the limit you need.
Energy consultants and assessors sell judgement. A client pays for an accurate assessment, a defensible rating, or advice on where to spend money to cut energy use or carbon — and then acts on it. That reliance is what creates liability: if the work falls below a competent standard and the client, or someone entitled to rely on it, loses money as a result, you can be held responsible for that loss.
Professional indemnity insurance responds to allegations of negligence, error or omission in your professional service. It typically meets two things: the cost of defending the claim — often the larger figure, and payable even when the complaint is unfounded — and any damages or compensation agreed or awarded, up to the limit and after the excess. The table below shows the kinds of claim an advisory energy practice can face and how cover answers them.
| What the claim alleges | How professional indemnity responds |
|---|---|
| A rating or certificate that proves wrong, so a property cannot be let, a transaction is delayed or renegotiated, or the certificate must be withdrawn and reissued | Defence costs for the allegation and compensation for the loss the error caused, within the limit and subject to the excess |
| Efficiency or retrofit advice the client acted on that fails to deliver — money spent on measures with a longer payback than advised | The cost of defending the claim and damages for expenditure mis-directed in reliance on the advice |
| Carbon or net-zero advice that leaves a client short of a reporting or compliance obligation | Defence costs and any award for the resulting loss, where it flows from a negligent act, error or omission |
| An audit or report relied on by a landlord, buyer, tenant or funder that turns out to be inaccurate | Your civil liability to the party entitled to rely on it, including the legal costs of resolving the dispute |
| A breach of confidentiality, or loss of a client’s building data or documents | The cost of putting matters right and liability for the resulting loss |
| An allegation that ultimately proves unfounded | The cost of investigating and defending it — which the firm would otherwise carry itself |
Cover responds to the service you advise on, not to the performance of plant or measures you neither designed nor installed — a boundary that matters, and one the next sections return to.
An energy assessment is rarely the end in itself. It is an input to someone else’s decision, and the people making those decisions are not only your paying client:
The wider the reliance, the larger the potential loss. A mis-stated rating is not simply a corrected document; it can mean a let property taken off the market, a capital programme built on the wrong numbers, or a funding decision that unravels.
The regulatory backdrop sharpens this. Minimum energy-efficiency standards for let property, mandatory assessment and certification regimes for buildings, and corporate energy and carbon reporting all turn your output into something a client must get right to stay compliant. When your work sits between a client and an obligation they have to meet, an error stops being academic — it becomes a compliance failure the client will look to recover.
Professional indemnity cover is built around the duty you owe: reasonable skill and care — not an assurance that a particular outcome will follow. You are not liable simply because a building underperforms or a measure disappoints; you are liable if you fell below the standard of a competent assessor or consultant. Three habits keep your exposure where the policy expects it to sit:
Membership of an accreditation scheme usually requires you to hold professional indemnity and to work to a code of conduct; it does not replace the cover or cap your wider liability at law. Insurers expect both the discipline and the policy.
Professional indemnity is almost always written on a claims-made basis: the policy that responds is the one in force on the day a claim is made against you, not the one in force when you did the work. Three consequences follow, and each matters to an energy practice whose assessments can be questioned years later.
Underpinning all of it is the Insurance Act 2015, which requires a fair presentation of the risk: you must disclose every material circumstance you know or ought to know — the kind of work you do, any change in scope, and any claim or circumstance that might give rise to one. Present the risk carelessly and an insurer can reduce or decline a claim; the time to get disclosure right is before you bind, not when you need to rely on the policy.
It is worth asking us to re-market your cover when:
We would rather say so than waste your time. We are probably not for you if:
There is no single statutory figure that applies to everyone. In practice the requirement comes from your accreditation scheme, which commonly makes professional indemnity a condition of membership, and from client or framework contracts that specify a limit and basis. The cover you need is therefore contract- and scheme-driven rather than set by one national minimum.
Yes. A rating or certificate is itself a professional judgement that others rely on. If an assessment is wrong and a landlord, buyer or funder loses money because of it, the claim is the same kind of civil liability that PI is designed to answer — whether or not you also gave advice.
Public liability covers injury to people or damage to property, such as a visitor hurt during a site visit. Professional indemnity covers financial loss caused by your advice, assessment or report. Most energy practices need both, because they answer completely different allegations.
It should, provided that work is within the activities declared to your insurer. Carbon and net-zero consultancy is advisory work like any other, and clients increasingly act on it to meet reporting obligations. Tell your insurer it forms part of your services so there is no argument about scope at claim time.
Not automatically. You owe reasonable skill and care, not a promise of a specific result. Liability turns on whether your assessment and projection were competently prepared and your assumptions clearly stated. Savings and payback are projections, and recording them as such is an important part of keeping an opinion defensible.
Because cover is claims-made, the policy in force when the claim is made is the one that responds — so a claim arriving after you stop trading needs run-off cover to answer it. Energy certificates and advice can be relied on for years, so arranging run-off when you wind down protects you against those late claims.
A great deal. Under the Insurance Act 2015 you must give a fair presentation of the risk, disclosing everything material you know or ought to know, including any change in the work you do and any circumstance that might lead to a claim. A careless or incomplete presentation can let an insurer reduce or refuse a claim, so accuracy at placement protects the cover you are paying for.
