Keeping continuity when a consultant leaves mid-application

When a named consultant retires, resigns or moves firms while your application is still under determination, the thing you lose is rarely the report. The PDF is already uploaded. What you lose is the author who can stand behind it, the native files the next person needs, and in the case of protected species work, the licence that makes the mitigation lawful. Deal with those three in the first week and the programme survives. Leave them and a case officer's question in month three becomes a six-week delay.

Architects feel this more than most, because they usually hold the coordination role without holding the specialist appointments.

What actually walks out of the door

Write down what the departing person was carrying. Four categories matter.

Authorship: whose name is on the title page and the sign-off, and whose competence the council is relying on. Our note on the named author and date on a planning report explains why councils treat that line as more than formality.

Data: survey sheets, meter files, model runs, metric spreadsheets, photographs with their metadata.

Judgement: the parts of the assessment that are not written down. The reason a particular receptor was chosen, the conversation with the county ecologist, the agreed scope of a survey that nobody minuted.

Statutory permissions: licences and registrations held in a personal name.

The first three can be recovered with effort. The fourth sometimes cannot be transferred at all.

Licences are personal to the holder

A European protected species mitigation licence is granted to a named individual, and class licences are held by registered individuals rather than by firms. If your ecologist leaves, the licence does not pass to a colleague because they work at the same company.

Natural England will consider a modification to substitute a new licensed ecologist, and the new person has to be satisfied with the survey work, the method statement and the mitigation design they are being asked to take responsibility for. In practice they will want to re-walk the site and re-read the survey data. Sometimes they will want a further survey, which is where the seasonal constraints bite: a bat emergence survey cannot be repeated in November.

The same logic applies in softer form elsewhere. A licensed assessor's registration, a competent person's standing for the statutory biodiversity metric and a fire engineer's professional registration all attach to the person. A firm can substitute a colleague of equivalent standing, but the substitution is a professional decision by the incoming person, not an administrative one by the project manager.

Ask early whether the incoming specialist will adopt the existing work or require more. That single question sets your programme.

Native files as well as the PDF

Request the working files in the handover, in writing, with a list. Noise survey logger files and calibration certificates. The hydraulic model, with its boundary conditions and the version of the software used. The biodiversity metric spreadsheet rather than a summary table. Arboricultural survey schedules with the tree reference numbers that match the drawings. Daylight model geometry.

Without them, the next consultant cannot test a scenario, respond to a consultee or amend a scheme without starting again. Rebuilding a model from a report costs more than the original model did.

Two practical points. Name the file formats in the request, because "all project data" invites a folder of PDFs. And ask for the raw survey records separately from the processed outputs, since the processed outputs are the part most likely to be regenerated by the incoming consultant anyway.

Copyright and the licence to use the report

Copyright in a report usually sits with the author or their employer, not with you, unless the appointment assigns it. What you normally hold is a licence to use the document for the project it was prepared for, and that licence is commonly conditional on fees having been paid.

So two things need checking before you rely on a departing consultant's report. Whether the fee account is clear, because an unpaid invoice can suspend the licence to use the document. And whether the licence extends to the use you now want, which may include submitting the report to an appeal, reissuing it with a new cover, or giving it to a replacement consultant to build on.

If the departing individual was a sole trader, the position is simpler and more fragile at the same time. There is no firm to hold the copyright, and no colleague to answer questions.

Reissuing someone else's report under a new name without their agreement is both a copyright problem and a professional conduct problem. Our piece on supervision chains and work signed by a chartered author sets out the distinction between supervising work and adopting it.

Re-issuing a report under new authorship

The incoming consultant has three honest options, and you should make them choose explicitly.

1. Adopt the report as it stands, re-issued with their name, a new revision number and a short statement of what they reviewed to satisfy themselves.
2. Issue an addendum that keeps the original document and records their review, any corrections and their position on the conclusions.
3. Replace the report.

Option two is the quickest and the most common, and it is usually acceptable to a council provided the addendum is clear about who is now responsible for what. Option one is fine for a short factual document and uncomfortable for a technical assessment with modelling behind it.

Tell the case officer what has happened. There is no statutory duty to do so unless the agent of record has changed, in which case the correspondence address has to be updated or you will miss consultation letters. But a short email setting out the change, the new author and the revised document list prevents the officer discovering it from a mismatch in the name on page one.

If the change needs a further survey or a new model run, ask for an extension of time in the same message rather than letting the determination period expire. An agreed extension is a better outcome than a refusal issued because the evidence was incomplete on the eighth week.

Appointment terms that prevent the problem

Four clauses do most of the protective work, and none of them is controversial enough to argue about at appointment stage.

A deliverables clause that lists native files alongside the report. A licence clause granting use of the material for the project, including for appeals and for reissue by a successor consultant. A continuity clause requiring the firm to provide a replacement of equivalent standing at no additional mobilisation fee if their named author becomes unavailable. And a data retention clause requiring survey records to be kept for a defined period and provided on request.

For protected species work, add a requirement that the appointment names the licensed individual and obliges the firm to notify you if that person's availability changes. It is a small thing that saves a survey season.

The honest uncertainty here is council tolerance. Some case officers will accept a one-page addendum signed by a new author without comment. Others will ask for the whole assessment to be reissued, particularly where the original author's competence was the reason a report was accepted at validation. You cannot predict which, so build a fortnight of slack into the programme and ask the officer rather than assuming.

If you need a replacement reviewer for a draft report, the PlanScope professional directory is the route for requesting review and sign-off, and our guide to changing consultant mid-application without losing the evidence base covers the commercial side of the switch.
