Ground (f) appeals and excessive enforcement requirements
Ground (f) is not a second bite at the merits. It attacks the requirements of the notice against the purpose the council chose, and it is won with a drafted alternative.
Ground (f) says the steps the notice requires exceed what is necessary. Not that the development is acceptable, not that the council should have negotiated, and not that compliance would be expensive. It compares the requirements against the purpose the council itself chose, and the purpose is written in the notice.
So the first thing to do on any ground (f) appeal is read the paragraph in the notice that states why it was issued. If the purpose is to remedy the breach, your alternative steps have to remedy the breach. If the purpose is to remedy injury to amenity, they only have to remove the injury. Those are very different jobs, and appellants who skip this read end up arguing the wrong one.
What ground (f) challenges
Section 174(2)(f) allows an appeal on the basis that the steps required by the notice to be taken, or the activities required to cease, exceed what is necessary to remedy any breach constituted by the matters alleged, or to remedy any injury to amenity caused by it.
The requirements sit in the notice under section 173, which also obliges the council to state the purpose. That statement is the yardstick. A notice requiring restoration of land to its condition before the breach, where the stated purpose is remedying injury to amenity, is vulnerable on ground (f) because restoration goes beyond removing the injury.
Ground (f) is also the place to attack requirements that catch things outside the breach. Removal of a hardstanding that was lawfully there before. Demolition of a wall that predates the works alleged. Cessation of activities the notice did not identify as unauthorised. Each of those is an over-requirement rather than a merits point.
Remedying the breach against remedying the injury
Set the two purposes side by side, because the difference decides most appeals.
| Remedy the breach | Remedy injury to amenity | |
|---|---|---|
| What the notice can require | Compliance with permission, or discontinuance and restoration | Steps that remove the harm |
| Scope for lesser steps | Narrow where the development itself is the breach | Wide, because harm can be mitigated |
| Typical successful argument | The requirement catches lawful features | Screening, reduction or relocation removes the injury |
| Evidence needed | The lawful baseline, evidenced | What the harm is and how the alternative removes it |
Where a building was erected without permission and the purpose is remedying the breach, ground (f) usually fails, because only removal achieves compliance. Where the purpose is amenity, the same building may be capable of being made acceptable by lowering a ridge, obscuring a window, moving a flue or planting a boundary. Those are the arguments that win.
The amenity route also invites the evidence you would deploy against a refusal on the same grounds, and overlooking and overbearing objections turn on the same material: sections, distances, angles and a view from the neighbour's window rather than from yours.
Proposing lesser steps that still work
Draft the alternative as if you were drafting the notice. Numbered requirements, in the imperative, each one capable of being complied with and checked by an officer standing on the pavement.
Vague is fatal. And reduce the height of the building is not a requirement. Reduce the ridge height of the building marked A on the attached plan to 4.2 m above the finished floor level shown on drawing 104 is.
Four things make an alternative credible.
- A plan or drawing showing exactly what the alternative leaves in place.
- A statement of how each step addresses the identified harm, point by point against the council's own reasons.
- Confirmation that the steps are physically and structurally achievable, from whoever will carry them out.
- A realistic period for each step, which links into ground (g).
Councils sometimes respond that your alternative is unenforceable. Answer that in advance by writing requirements that need no judgement to police.
Where an inspector will vary a notice
Section 176 lets the decision maker correct a defect, error or misdescription in the notice, or vary its terms, provided the correction or variation causes no injustice to the appellant or to the authority. That is the machinery through which a successful ground (f) takes effect.
The no injustice test is worth keeping in mind when you draft. An inspector cannot rewrite a notice into something materially different from what was served, because the council and any interested party would not have had the chance to respond to it. Alternatives that stay close to the notice's own subject matter are far more likely to be adopted than alternatives that reconstruct the scheme.
Expect the inspector to set a fresh compliance period when varying, and expect the varied notice to take effect on the date of the decision.
Interaction with the compliance period
Ground (g) argues that the period allowed falls short of what should reasonably be given. It is a different ground and it needs its own evidence: what has to be done, in what sequence, with what lead times for contractors, materials or seasonal constraints.
Pair the two deliberately. If your lesser steps involve a structural alteration, say how long design, building control approval and construction will take, and ask for a period that matches. An inspector given a reasoned programme will usually adopt it. An inspector asked for twelve months with no explanation will give three.
Where removal of soil or hardcore is required, the disposal route and any waste permitting can drive the whole timetable, and saying so in a sentence with a date attached is more persuasive than a general plea about cost.
Evidence needed to support alternative steps
Three categories, and the appeal turns on the first.
The lawful baseline. What was lawfully on the site before the breach, evidenced by photographs with verifiable dates, historic mapping, earlier permissions and drawings. This is what demonstrates that a requirement goes too far.
The harm. The council's stated harm, taken from the notice and from the officer's report, addressed item by item. Do not invent a different harm to argue against.
The deliverability. A short letter from a builder or engineer confirming the alternative can be built, with an indication of timescale. Not a costing exercise, because cost is not the ground (f) test, though it becomes relevant if you also run ground (a) and the planning balance.
Where you do run ground (a) as well, the merits case needs proper support, and a Planning Statement addressing the development plan policies the council relied on does that work. Keep it separate from the ground (f) material so the inspector can see which argument is which.
Common drafting mistakes
Five recur.
Arguing the merits. A statement of case that says the extension causes no harm and should be allowed to stay is a ground (a) argument wearing a ground (f) label, and it will be treated as such.
Offering no alternative. Ground (f) asserting that the steps go too far, without saying what would be enough, gives the inspector nothing to vary the notice to.
Ignoring the stated purpose. An alternative built around mitigating harm, where the notice's purpose is remedying the breach, misses the test entirely.
Proposing something that needs permission. If your lesser steps would themselves be development requiring consent, say how that will be obtained, because a varied notice cannot require unlawful works.
Leaving the plan out. As an illustrative example, a notice requiring demolition of a detached outbuilding and removal of all associated hardstanding, where part of the hardstanding served a pre-existing garage, is a strong ground (f) case with an annotated site plan showing the two areas, and a weak one without it.
Read the notice the way an inspector will, in the order it is written, and check every requirement against the purpose. The same discipline applies to a refusal, and reading a notice against the plan is the habit worth building.

Frequently asked questions
What exactly does ground (f) say?
That the steps required by the notice, or the activities required to cease, exceed what is necessary to remedy the breach of planning control or to remedy any injury to amenity caused by it. Which of those two purposes applies depends on what the council stated in the notice, so read the purpose paragraph before drafting anything.
Can ground (f) keep an unauthorised building standing?
Rarely, where the breach is the building itself and the stated purpose is to remedy the breach, because nothing short of removal achieves that. It can succeed where the stated purpose is remedying injury to amenity, since screening, partial reduction or a change of finish may remove the injury while leaving the structure. The notice's own wording decides which case you are in.
What happens if ground (f) succeeds?
The inspector normally varies the notice rather than quashing it, using the power to correct or vary terms where doing so causes no injustice to either party. You end up with a notice requiring your lesser steps, running from a compliance date the inspector sets. That is a good outcome and it is still a notice on the planning record.
How does ground (f) relate to ground (g)?
Ground (g) says the compliance period is too short, and it is a separate argument about time rather than about content. They pair naturally, because lesser steps may need a different timetable from the steps the council required. Plead both where relevant and give the inspector a period with a reason attached.
Is there a risk in narrowing the notice?
There is a benefit you should know about. Where a notice could have required works to be removed or an activity to cease but does not, and all its requirements are complied with, planning permission is treated as granted for what is left. So a successfully narrowed notice can leave lawful development behind, which is why councils resist ground (f) more firmly than appellants expect.
