Reusing a report on another site or scheme

Copyright in a technical report or a set of drawings belongs to the person who created it, not to the client who paid for it, unless there is a written assignment. What the client normally gets is a licence to use the material for the project it was prepared for. So reusing a consultant report on another site is usually outside the licence, and reusing a report prepared for a previous applicant is usually outside any licence you hold at all.

That is the rule under the Copyright, Designs and Patents Act 1988, and it surprises people every week. The invoice does not transfer the copyright.

Who owns the report and who owns the copyright

Three things can be owned separately and often are.

The physical or digital copy of the report, which the client plainly has.

The copyright in the text, drawings, calculations and photographs, which stays with the author unless assigned in writing and signed by the assignor.

The right to rely on the report's conclusions, which depends on the appointment and on any reliance letter, and which is a separate question from copyright altogether.

A client can hold a report, be entitled to use it on the project, and still have no right to publish it elsewhere or reuse it on a different site. Moral rights add a fourth layer: an author who has asserted the right to be identified can object to their work being used without attribution, and to derogatory treatment of it.

Assignment is the only thing that transfers ownership, and section 90 of the 1988 Act requires it to be in writing and signed. A verbal agreement, an email saying the drawings are yours, or a line in a fee proposal saying copyright passes on payment without more are all weaker than people assume.

Licence to use against transfer of ownership

Most appointments grant a licence. The scope of that licence is the question, and the drafting usually turns on four variables.

Where the appointment is silent, the courts have been willing to find an implied licence allowing the client to use drawings for the purpose for which they were commissioned, which on a building project means constructing that building on that site. The implied licence does not stretch to a second site, a second scheme, or a sale of the material to someone else.

Two practical readings follow. A house type drawing used on a second development is a new use needing a new licence or a fee. And a planning statement written for one application, with the site address and policy analysis changed, is a derivative work rather than a new document.

Unpaid fees and suspension of licence

Many appointments make the licence conditional on payment of fees. Where that term is present and fees are outstanding, the consultant can withdraw permission to use the material, and that includes material already submitted with a planning application.

The effect is awkward rather than fatal. The authority will not usually remove documents from its register at a consultant's request, because it has its own statutory duty to make application documents available. What the consultant can do is refuse further use, refuse to provide the native files, decline to issue amended drawings, and write to the client and sometimes to the authority stating the position.

Where the appointment is silent on payment, the position is less certain, and that uncertainty is itself a reason to settle disputed fees rather than litigate the copyright point. A disputed invoice of a few thousand pounds costs less to resolve than a stalled application.

Reports prepared for a previous applicant

This is the common situation on a site bought with a planning history. The previous applicant's documents are sitting on the authority's public register, they are relevant, and the temptation is to resubmit them.

Three separate problems.

Copyright, because the previous applicant's licence does not pass to you with the land unless it was assigned.

Reliance, because the consultant owes you no duty of care, so if the report is wrong you have no claim. That matters most on ground conditions, contamination, structural and flood matters.

Currency, because a document prepared three or four years ago may cite a superseded Framework edition, an old local plan or a superseded version of a technical standard.

The practical answer is almost always to go back to the original author. Most consultants will provide the report to a new client with a fresh licence and often a short updating review, for a fee well below the cost of starting again. They have the file, the survey data and the site knowledge, and they would rather be paid than argue.

Where the original author refuses or no longer exists, commission new work. Resubmitting someone else's report with the cover page changed is a risk on three fronts at once, and the professional competence question sits alongside it, as our note on competence for visual assessment work sets out for one discipline.

Updating rather than reusing

An update is a different commission from a reuse, and it is the route that keeps everything clean.

The author retains copyright and grants a licence to the new client. The author takes responsibility for the updated conclusions, so reliance works. The update can address the things that have changed: the Framework edition, the adopted local plan, survey data that has aged, the metric version for biodiversity calculations.

Price it as a review and revision rather than a new report. For a planning statement the policy section may need rewriting while the site description stands. For a design and access statement the opposite is often true, because the design has changed and the context has not.

What to agree at appointment

Five clauses settle this at the start, and consultants rarely resist them if they are raised before the work begins.

1. An irrevocable, non-exclusive, royalty-free licence to use, copy and modify the material for any purpose connected with the site, including applications, construction, marketing and sale.
2. A right to sub-licence to funders, purchasers, tenants and their professional advisers.
3. Confirmation that the licence is not conditional on payment, or if it is, that it revives on payment of undisputed sums.
4. An obligation to provide native files on request, with a stated format and turnaround.
5. Where you want ownership rather than a licence, an express assignment in writing, signed, with the consultant retaining the right to use the material for their own portfolio and records.

Clause five is worth asking for and often refused, and a broad irrevocable licence achieves nearly the same commercial result. Pushing for assignment on a modest commission usually costs more in negotiation than it is worth.

Keep the appointment, the licence terms and any reliance letters in the same file as the reports themselves. On a site that changes hands twice before it is built, that file is what makes the technical pack worth something. The professional directory is the route to a reviewer who can take ownership of a draft and sign it off, and the full report index sets out what each document type covers.
