Planning Appeal Support in London

After a refusal there are usually two routes: appeal the decision to the Planning Inspectorate, or submit a revised application that addresses the reasons for refusal. The right choice depends on how sound the council’s reasons are, the strength of the policy position and your timescale. We review the decision notice and officer’s report, advise honestly on prospects, and prepare the drawings and design case for whichever route is stronger. We do not guarantee an outcome; the decision rests with the Inspector or the authority.

A successful appeal answers the specific reasons an application was refused — design, amenity, heritage impact or policy conflict. We prepare a clear, evidenced case: revised or annotated drawings, a design rationale and the supporting statements the appeal requires, coordinated with a planning consultant who leads the written representations, hearing or inquiry. Most householder appeals proceed by written representations, which keeps cost and time proportionate.

Appeals are decided in one of three ways, and the route shapes the cost, the timescale and the formality. The great majority of householder and minor appeals are dealt with by written representations — an exchange of statements that the Inspector considers on the papers, often with a site visit — which keeps things proportionate. More complex or contested cases may go to an informal hearing, and the largest or most contentious to a full public inquiry with advocates and witnesses. We advise which route your appeal falls into and prepare the design case accordingly.

Appeals are time-limited: broadly twelve weeks from the decision for a householder application and six months for most others, and the deadline is strict. The Inspector re-determines the proposal afresh against national and local policy, but on the basis of the scheme that was refused — an appeal is not an opportunity to submit a substantially different design, which is one reason a revised application is sometimes the better route. We make sure the case is built around the policy issues the Inspector will actually weigh.

There is no fee to lodge a planning appeal, but it takes months to determine, and costs can be awarded against a party that has behaved unreasonably in the process. Set against a revised application — which is often quicker and more certain where the council’s concerns are reasonable — the appeal route has to be chosen deliberately, not as a reflex. We give an honest view of the prospects and the trade-offs before you commit, so the decision to appeal is made on a clear-eyed assessment rather than frustration.

Not every refusal should be appealed. If the scheme can be amended to address officer concerns, a fresh or revised application is often faster and less adversarial. If the refusal turns on a point of principle you still believe is supportable, written representations or a hearing may be appropriate. We recommend the path with the better risk-adjusted outcome, not the path that maximises process.

Deadlines for appeal are strict. Contact us promptly after the decision notice.

A strong appeal addresses each refusal reason with policy, drawings and, where needed, specialist evidence such as daylight analysis. Re-arguing taste without evidence rarely works. We prepare a focused case and, where we did not author the refused scheme, we still need full access to the original submission materials.

Inspector decisions are independent. We do not promise outcomes.

A successful appeal still leaves conditions, building regulations and any freeholder consents. An unsuccessful appeal may still leave a route via redesign. We help you read the decision for what to do next, not only for win/lose.

Costs awards are uncommon in householder written representations; budget for professional fees without assuming the other side pays.

Refusal is not the only trigger for an appeal. If the council fails to determine an application within the statutory period, around eight weeks from validation for householder and minor schemes unless an extension has been agreed, a right of appeal against non-determination arises. In practice a short agreed extension is often the more productive route, because it keeps the conversation with officers alive rather than handing the file straight to an Inspector. Separately, where permission is granted but a condition makes the consent unworkable or expensive to satisfy, an appeal can be made against the condition itself rather than the decision as a whole.

Both routes need the same clear-eyed weighing as a refusal appeal. A non-determination appeal takes the decision out of the council's hands entirely, which forfeits any chance of negotiating amendments once it is lodged. A conditions appeal puts the permission back before an Inspector, who considers the planning merits afresh, so a marginal consent can in principle be put at risk over a condition that might have been resolved by discussion, by an application to vary it, or simply through the discharge of conditions process. We advise on which of those tools fits before an appeal becomes the default, because the least adversarial route that solves the problem is usually the right one.

An appeal is decided on planning merits, and one of the strongest cards a householder can hold is a genuine fallback: something that could lawfully be built anyway, without the permission being fought over. Where a refused scheme is close in scale and impact to what permitted development rights would allow, an Inspector can treat that fallback as a material consideration, because refusing the application achieves little if a similar volume could be built regardless. The fallback has to be real rather than theoretical, and it carries most weight when it is evidenced, which is why it is often worth establishing formally before or alongside the appeal.

We test the fallback early because it shapes the whole strategy. Permitted development advice establishes what the true baseline is for your property, since rights vary with property type, previous extensions and any Article 4 direction, and a lawful development certificate turns that assessment into evidence an Inspector can rely on rather than an assertion to be argued about. Other material considerations matter too: the development plan read as a whole, relevant appeal decisions on comparable sites and the pattern of what the council has itself approved nearby. The design case we prepare draws these threads together, and honest advice sometimes follows from the same exercise, because a strong fallback can make a revised application the smarter route than an appeal at all.

Lodging the appeal is the beginning of a managed procedure, not the end of the work. The Planning Inspectorate first checks the appeal is valid and in time, then issues a start date that fixes the timetable for everything that follows. The council passes over its file, including the representations neighbours made on the original application, which carry across automatically, and interested parties are notified so they can comment again. On the written representations route that decides most householder cases the exchange is deliberately compact, with little or no opportunity to add material later, which is why the case needs to be complete on the day it is submitted.

An Inspector will usually visit the site, often unaccompanied in straightforward householder appeals, so the property should match the submitted drawings and the proposal should be legible on the ground from the plans alone. While the appeal is pending we advise clients not to start work in anticipation of success and not to redesign mid-process: the Inspector decides the scheme that was refused, and substantive changes belong in a fresh application if one proves necessary. The waiting period is rarely wasted, though. It is often the right moment to test a contingency design quietly, so that whichever way the decision letter goes there is a considered next step ready rather than a scramble.
