Heritage and archaeology
Yes. If you produce desk-based assessments, evaluations, monitoring or excavation reports for developers, you need professional indemnity insurance, and CIfA makes it a condition of its Registered Organisation scheme. Your conclusions shape land deals, layouts and construction programmes. When remains nobody predicted stop the diggers, or a report understates what is in the ground, the client’s loss is delay and redesign rather than injury. Public liability does not cover that. PI does, subject to the policy terms.
Part of: Professional indemnity for consultants
In short
Commercial archaeology in England works to the National Planning Policy Framework, which since August 2026 sets heritage policy out as policies HE1 to HE10. Policy HE5 expects a desk-based assessment and, where necessary, a field evaluation wherever a site may hold archaeological interest. CIfA standards bind members and Registered Organisations, and CIfA requires Registered Organisations to hold PI. The main claims are missed or understated remains that cause delay, works that damage a scheduled monument, mishandled human remains or treasure, and report errors that hold up planning conditions. PI responds to negligence; it does not turn an evaluation into a guarantee.
Last reviewed 5 October 2026 by the Apex professional indemnity team.
Developers, planning consultants and infrastructure clients pay you for a professional opinion about what is in the ground and what should happen to it. A desk-based assessment can decide whether a site is bought and at what price. An evaluation decides the mitigation strategy and the programme. A post-excavation report decides whether a planning condition can be discharged. If any of those opinions is wrong, the client’s loss is financial: standing time, redesign, a delayed sale or a land price that no longer makes sense.
Public liability (PL) is built for a different kind of event: a trench that undermines a neighbour’s wall, a cut gas pipe, a member of the public who falls into an open excavation. It responds to accidental injury and property damage. It does not pay for a misjudged risk assessment, a misread geophysics plot or a report the planning authority will not accept.
Some incidents involve both. If your team digs into a scheduled earthwork because your constraints plan put the boundary in the wrong place, the physical damage and the professional error behind it may fall to different policies. Make sure your PI and PL dovetail.
The scenarios below are illustrative, not real claims. They show the kind of allegation archaeologists face.
In each case the client argues that a competent archaeologist would have designed, interpreted, reported or attended differently.
Most disputes compare your work with planning policy, CIfA standards and the statutory regimes that govern what happens on site. These are the main reference points in England.
| Reference point | What it says | Why it matters to you |
|---|---|---|
| NPPF (August 2026), policy HE5 | Proposals affecting heritage assets need a proportionate assessment of significance and effect, using the Historic Environment Record. Where a site has or may have archaeological interest, an appropriate desk-based assessment and, where necessary, a field evaluation should inform design and mitigation. Decision-makers should be satisfied that assessments accurately reflect effects. | Your assessment and evaluation are the evidence a planning decision rests on. |
| NPPF policy HE10 | Archaeological interest should be preserved in situ where feasible. Otherwise investigation, recording, dissemination and archiving should be done by suitably qualified people or organisations, and the evidence and archive made publicly accessible. | Your obligations run beyond the trench, through reporting and archive deposition. |
| CIfA Standards and guidance | Binding on members and Registered Organisations. A desk-based assessment determines, as far as reasonably possible from existing records, the nature, extent and significance of the historic environment. An evaluation determines the nature, extent, preservation and significance of remains in a defined area, ending in a report and an archive. | A claim will measure your work against the standard for that type of project. |
| CIfA Code of conduct | Members must not give advice without being as thoroughly informed as might reasonably be expected, must know and comply with the law that applies to their work, and must maintain adequate insurance for persons or property their work may affect. | A poorly informed opinion can be both a conduct issue and the basis of a negligence claim. |
| Ancient Monuments and Archaeological Areas Act 1979, s.2 | Works that damage, remove, repair or alter a scheduled monument, or flood or tip on its land, need written consent from the Secretary of State. Working without consent, or breaching its conditions, is an offence, with a defence for someone who did not know and had no reason to believe the monument was in the affected area. | A misplaced boundary on your plan can expose a client to prosecution and you to a claim. |
| Treasure Act 1996, s.8, and Code of Practice (3rd revision, 2023) | A finder must notify the coroner within 14 days of the find, or of realising it may be treasure; failing to do so is an offence. Teams on planned excavations must report potential treasure and cannot claim a reward, though the landowner can. | Finds procedures are part of your professional competence, and landowners watch them closely. |
| Burial Act 1857, s.25 | Removing buried human remains from a place of burial is an offence without a faculty, a cathedral approval or a Secretary of State licence. The Ministry of Justice licenses the excavation of human remains on archaeological sites in England and Wales. | Unexpected burials stop work until the right authority is in place. |
This is where archaeology claims are won or lost. An evaluation fee is small next to the cost of a stalled programme: plant standing idle, contractors claiming for disruption, sales slipping, finance running on. When something significant turns up late, the developer reads your earlier reports first.
An evaluation is a sample. Policy HE5 asks for one “where necessary”, and CIfA defines it as fieldwork to determine the presence or absence of remains within a defined area. Nobody can promise that a sample finds everything, and finding more later is not in itself negligence. The real questions in a claim are whether your design was reasonable for what the Historic Environment Record, aerial photographs and geophysics already showed, and whether your interpretation and wording were fair to the evidence.
Developer appointments sometimes ask you to warrant that a site holds no further archaeology, to accept liability for programme delay, or to pay liquidated damages if a report is late. Those promises go beyond reasonable skill and care, and PI wordings often exclude liability you take on only because the contract says so. Negotiate a liability cap, keep obligations to reasonable skill and care, and check any collateral warranty against your policy before you sign. See collateral warranties and PI.
| Usually covered by PI | Often excluded or limited | Needs a different policy |
|---|---|---|
| Negligent desk-based assessment, geophysics interpretation or evaluation design that leads to delay or redesign | Fines and penalties, such as those following a prosecution under the 1979 Act, which PI wordings commonly exclude | Damage to buried services or neighbouring property while digging (public liability) |
| Report and archive errors that force rework or hold up discharge of a planning condition | Warranties that a site is clear of archaeology, or other fitness for purpose promises | Injury to site staff and volunteers (employers’ liability) |
| Claims from funders or buyers under collateral warranties, where the policy extends to them | Liquidated damages for late reports | Survey instruments, geophysics kit and site cabins (equipment or contractors’ all risks cover) |
| Defence costs, including expert evidence on fieldwork methods | Pollution and asbestos encountered in the ground | Finds and archives held in your store (property cover) |
| Loss of or damage to project records, where documents cover is included | Circumstances you knew about before the policy started | Site vehicles (motor) |

CIfA requires a Registered Organisation to have PI, or in exceptional cases equivalent arrangements through its constitution or parent body, but its regulations do not set a figure. In practice the limit comes from your clients. Developers, infrastructure promoters and public bodies set a minimum in the appointment or framework, and some ask for it to apply each and every claim rather than in the aggregate.
Size the limit by what a stalled programme could cost the client, not by your fee: a small evaluation on a large site can carry an exposure out of all proportion to what you charged. If an appointment asks for more than you hold, raise it before you sign: see when a contract requires a higher PI limit.
Archaeology claims tend to arrive late. A desk-based assessment may support a land purchase years before groundworks start, and the problem only appears when the machines reach the remains. PI is claims-made, so the policy that responds is the one in force when the claim is made. Keep cover continuous between projects, check retroactive dates when you change insurer, and arrange run-off if you wind up a unit, merge or retire. See run-off cover explained.

Yes, if you advise clients or carry out fieldwork for them. Developers rely on your assessments, evaluations and reports to buy land, plan programmes and discharge planning conditions, and a negligent judgement can cause large delay costs. Public liability does not cover that kind of financial loss. PI covers your liability for it, subject to the policy terms.
No statute requires it. CIfA does, for its Registered Organisation scheme: its regulations make PI a condition of registration, with alternative arrangements accepted only in exceptional cases. CIfA’s Code of conduct also requires members to maintain adequate insurance for persons or property their work may affect. Developers commonly require PI in appointments too.
It can, if the client alleges your evaluation design or interpretation was negligent, subject to the policy terms. Finding more archaeology later is not negligence in itself, because an evaluation is a sample. Clear statements of sample size, limitations and residual risk are your clearest evidence that the work was reasonable.
Under section 25 of the Burial Act 1857, removing buried human remains from a place of burial without the right authority, such as a Ministry of Justice licence or a faculty, is an offence. Work in that area usually pauses until authority is in place. A delay claim based on negligent advice may fall under PI, but fines are commonly excluded.
Possibly. If the plan was negligent, the client’s claim for reinstatement, delay and legal costs is the kind of loss PI is designed for, subject to the terms. Any fine the client or you receive under the 1979 Act is commonly excluded. Check monument boundaries against current official records, not old base maps.
Only in part. A documents extension may pay to restore lost or damaged records, up to a sub-limit. Finds are physical objects, not documents, and they are not yours, so they need property cover while you hold them. Policy HE10 expects the archive to end up publicly accessible, so plan deposition early.
