Objecting to a section 73 variation application

A section 73 variation objection is worth making, because a section 73 application is a real application for planning permission with real consultation rights, and the outcome is a new permission rather than an amendment to the old one. What you cannot do is reopen the development itself. Section 73(2) of the Town and Country Planning Act 1990 directs the council to consider only the question of the conditions subject to which permission should be granted.

So the useful objection is about the effect of the change, evidenced, and about whether the conditions that protected you are still there.

What a section 73 application can change

Section 73 allows an applicant to seek permission to develop land without complying with a condition attached to an earlier permission. In practice that covers varying a condition, removing one, or substituting approved drawings where a condition ties the development to them.

The range is wider than it sounds. Changing the approved plans condition is how most design changes come forward, so a section 73 application described on the council's website as "variation of condition 2 (approved plans)" may be proposing a different roof form, a relocated access or an extra storey.

What section 73 cannot do is change the description of development on the original permission. A permission for four houses cannot become a permission for six through section 73. The Levelling-up and Regeneration Act 2023 added a separate power to vary permissions more broadly, so check whether it is in force and how your council is applying it, because the answer affects which route an applicant can use.

Why it creates a fresh permission

A successful section 73 application produces a new planning permission. The original permission stays in place, unimplemented and still capable of being built out, until it expires.

Two consequences follow for an objector. The first is that an applicant who is refused a variation still holds the original consent, so "refuse this and the scheme goes away" is almost never true. The second is that the new permission has its own conditions, and the question of whether every protective condition from the original has been carried over is a genuine one.

The Supreme Court has held that a section 73 permission has to be read in its context rather than in isolation, so a restriction left out of the new notice may still be treated as applying. That is reassuring in principle and unreliable in practice, because enforcement officers work from the notice in front of them. If a condition you rely on is missing from the draft decision, say so in writing during the consultation.

Matters reopened and matters closed

The practical test is whether the thing you want to say is about the change or about the original decision. An objection arguing that the site should never have been developed will be set aside. An objection showing that the proposed roof is 1.2 m higher than the approved one and now overlooks a bedroom window at 9 m will be assessed.

Publicity requirements on a variation

This is where section 73 differs usefully from later stages. Because it is an application for planning permission, the statutory publicity requirements in article 15 of the Development Management Procedure Order 2015 apply: the council must publicise it by site notice, neighbour notification or advertisement depending on the type of development.

So you should be told, and if you were not, that is a point to raise. Compare that with an application to approve details reserved by condition, which is normally not publicised at all, and with the uneven treatment of reserved matters applications.

The consultation period is usually 21 days. Comments after that are still normally considered while the application is undetermined, but the officer's report is written at the end of the determination period, so earlier is better. Where amended plans come in mid-course, whether you get a second look depends on the council's practice, which is the subject of are neighbours reconsulted on amended plans.

Conditions carried forward or lost

Make a list. Take the original decision notice, write out every condition, and check each one against what the section 73 application proposes and against the officer's draft recommendation if you can see it.

The conditions most often lost in translation are the ones that protect neighbours rather than the development: obscure glazing to a flank window, a restriction on roof terraces, a boundary treatment specification, a tree protection scheme, a restriction on use of a yard, hours of delivery, or a condition removing permitted development rights for extensions.

Removal of a permitted development restriction deserves particular attention. If the original permission removed householder permitted development rights to stop further extensions on a tight plot, and the new permission does not, the scheme has quietly gained a lot of flexibility.

Learning to read the notice properly is most of this work, and reading a decision notice as a neighbour sets out how the parts fit together.

Cumulative variations over time

On a long-running site you may be looking at the fourth or fifth section 73 permission. Each one was assessed against its predecessor, and the cumulative distance from the original approval can be substantial without any single step having looked significant.

Ask the council, in your objection, to set out the position against the original consent rather than against the last variation. That is a fair request, and officers will often do it when asked because committee members ask the same question.

Keep your own schedule: the reference numbers, the dates, what each variation changed. It takes an hour and it is the single most useful document a resident can bring to a committee meeting.

Objecting on the right basis

Write short and specific. Name the application reference, the condition being varied, the drawing numbers for the approved and the proposed scheme, and the policy in the local plan you say is breached.

Then describe the effect in measurable terms: the increase in height, the distance to your window, the change in the angle of view, the loss of the screen planting, the additional vehicle movements past the junction. Officers can use measurements. They cannot use "out of keeping".

Three further asks are worth including. Request that any condition from the original permission which protects neighbouring amenity is reimposed, listing them by number. Request that the development be assessed against the original approval as well as the last variation. And ask whether the application will be decided by committee or under delegated powers, so you know whether to seek to speak.

If the works then depart from what was approved, the route is enforcement rather than objection, and breach of condition notices are the tool the council reaches for first.
