Does a section 73 application need a new fire statement
A section 73 grant is a new planning permission, and article 9A attaches to applications for planning permission. That makes the starting point yes, with sensible exceptions.
The section 73 fire statement question has a straightforward starting point that people resist because of its consequences. A grant under section 73 of the Town and Country Planning Act 1990 creates a fresh planning permission rather than editing the old one. Article 9A of the Development Management Procedure Order requires a fire statement to accompany an application for planning permission for development involving a relevant building. A section 73 application is an application for planning permission. So where the development involves a relevant building, the duty applies on the face of the order.
What varies is how authorities administer it, and whether the substance of the statement needs to change at all. Those are different questions from whether the form is required, and conflating them is what produces validation disputes.
What a section 73 grant actually creates
Section 73 allows an application for planning permission for the development of land without complying with conditions attached to a previous permission. If the authority grants it, the result is a new permission, subject to the conditions it specifies, sitting alongside the original permission rather than replacing it.
Two practical consequences follow. The original permission survives and can in principle still be implemented. And the new permission carries its own conditions, its own approved plans and its own compliance obligations from the date it is granted.
That is why a section 73 is not a paperwork exercise. It is a determination of a fresh application, with fresh consultation, a fresh decision and a fresh set of duties attaching to the submission.
Why the duty attaches again on the face of the order
Read article 9A literally and the analysis is short. The requirement is triggered by an application for planning permission for development which involves the provision of one or more relevant buildings, or development of an existing relevant building.
A relevant building contains two or more dwellings, or educational accommodation, and meets the height condition of 18 metres or more, or seven or more storeys, measured to the floor surface of the top storey.
Nothing in that wording carves out variations. If the development to which the section 73 application relates involves a relevant building, the application is within scope, whatever the condition being varied happens to be about.
The Health and Safety Executive is a consultee on applications for relevant buildings, which means a section 73 within scope may be re-consulted. Programme for that. A variation expected to take eight weeks on a delegated track can take considerably longer once a statutory consultee is in the loop.
Variations that plainly need a fresh statement
Some variations change the fire case and the statement has to change with them:
- Any increase in height, particularly one that takes a building across the 18 metre or seven storey threshold when it was previously below it.
- Changes to core position, stair numbers or stair width.
- Changes to the external wall construction, cladding specification or balcony arrangement.
- Changes to the number, size or layout of dwellings that affect travel distances or occupancy.
- Changes to site layout affecting fire appliance access routes, hardstanding positions or turning.
- Changes to the position or provision of firefighting water supplies.
- A change of use bringing educational accommodation into a building that previously had none.
The first of those deserves emphasis. A building below the height condition when permitted, varied upwards past it, becomes a relevant building for the first time at the section 73 stage. The duty then applies to an application that the original permission never engaged, and the applicant who assumed continuity is the one caught out. The structural consequences travel with it, as set out in disproportionate collapse and building class in design.
Variations that plainly do not
Most section 73 applications on large schemes are about conditions that have nothing to do with fire. Varying the wording of a landscaping condition, adjusting the trigger point for a materials sample, extending permitted construction hours, amending a drainage discharge condition or correcting a plan reference does not change the fire strategy in any respect.
In those cases the substance of the approved statement is unchanged. What the authority needs is confirmation of that, not a new document.
The practical answer is to submit the published form with a short covering note. State the reference of the approved fire statement, its version and date, confirm that the proposed variation does not affect any matter addressed in it, and explain in two sentences why. That is a ten minute task and it forecloses the validation argument entirely.
Submitting nothing and hoping is the approach that costs a fortnight.
Section 96A and the newer variation route
Section 96A is different in kind. An application for a non-material amendment is not an application for planning permission; it amends an existing permission. The article 9A duty does not attach to it.
That is a limited comfort, because a change capable of affecting the fire strategy is very unlikely to be non-material. If a change is small enough for section 96A, it is very probably small enough not to affect the fire case. Where an agent is arguing that a material fire-related change can go through section 96A, that is the point to push back.
The Levelling-up and Regeneration Act 2023 introduced a further route for varying permissions, framed around changes that are not substantially different from the original. Whether it is in force, and what procedural requirements attach to it, depends on the commencement regulations made under that Act. Check the current position on legislation.gov.uk before advising on it, and do not assume that a new route carries the same consultation and documentation obligations as section 73.
Settling the point with the case officer
Raise it before submission, not at validation. A short email works:
- Identify the permission, the condition to be varied and the proposed new wording.
- State whether the building is a relevant building and give the height measurement.
- State your position on whether the approved fire statement is affected, with reasons.
- Ask whether the authority requires the form submitted with a no-change confirmation, or a revised statement.
- Ask whether the Health and Safety Executive will be consulted, since that affects the timetable.
Authorities answer this readily because they would rather settle it in advance than reject a submission. Keep the reply.
Where the answer is that a revised statement is needed, the revision has to be prepared by someone with the necessary fire engineering competence. This is a report type where a competent professional is legally required, not merely advisable, and an AI-assisted draft is a starting point for that professional rather than a replacement. A Fire Statement and the underlying Fire Safety Strategy should be revised together, because a statement that no longer matches the strategy is worse than no revision at all.
Recording the position on the file
On a scheme that sees four or five section 73 applications over its life, the record is what prevents drift.
Keep a single table listing every application affecting the building, the date, what was varied, whether a fire statement accompanied it, the version submitted, and the consultee response. Add a line for each condition discharge that touched a fire matter.
That table answers the question that arrives at Gateway Two, when the Building Safety Regulator asks what was assessed at planning and on what basis. It also answers the question that arrives when the project changes hands, which on a six-year scheme it will.
The wider index of report types by category sets out which documents carry professional requirements of this kind and which do not.
This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.

Frequently asked questions
Does section 73 create a new planning permission?
Yes. A grant under section 73 is a fresh planning permission subject to the conditions the authority specifies, sitting alongside the original rather than replacing it. The original permission survives and can in principle still be implemented. That is why the submission duties that attach to an application for planning permission apply again.
Can I submit a section 73 without a fire statement if nothing fire related changes?
Practice varies by authority. The safer course is to submit the published form with a short covering note giving the reference, version and date of the approved statement and confirming the variation does not affect it. That takes minutes and removes the validation argument, which is the expensive part.
What if the variation takes the building above 18 metres?
Then it becomes a relevant building for the first time at the section 73 stage, and the article 9A duty applies to an application the original permission never engaged. A full fire statement is needed, the Health and Safety Executive is likely to be consulted, and the programme should allow for it.
Does a non-material amendment under section 96A need a fire statement?
No, because an application under section 96A amends an existing permission rather than seeking planning permission, so article 9A does not attach. In practice this rarely helps, since a change capable of affecting the fire strategy is very unlikely to qualify as non-material in the first place.
Will the Health and Safety Executive be consulted again?
Where the section 73 application is within the scope of the duty, it may be. Consultation adds time to what applicants often assume is a quick delegated decision, so confirm the authority's intention before submitting and build the statutory consultation period into the programme rather than discovering it afterwards.
