Refused by the Royal Borough of Kensington and Chelsea? We read the decision notice, tell you honestly whether to appeal or resubmit, and prepare the drawings and statement that answer each reason for refusal on the Planning Inspectorate's terms.
the Royal Borough of Kensington and Chelsea granted 85% of the householder planning decisions it made in its latest published year — 2 points below the 87% England-wide householder average. The borough runs the strictest basement policy in London — broadly one storey deep, under no more than half the garden, with a construction traffic management plan, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837) and Victorian (1837–1901) housing stock sets the design brief on most streets.
Under Class B, a rear dormer stays permitted development up to 40m³ of added roof volume on a terrace or 50m³ on a semi-detached or detached house, while Class A allows a single-storey rear extension of 3m beyond the original rear wall on a terrace and 4m on a detached house before a full application is needed. Kensington and Chelsea carries at least one Article 4 direction, and conservation areas including Chelsea, Kensington and Holland Park remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Kensington and Chelsea is determined against an 8-week statutory target.
Chelsea (stucco terraces and mews streets off the King's Road), Kensington (grand stucco terraces and mansion blocks), Notting Hill (the Ladbroke Estate's stucco terraces around communal garden squares), Holland Park (large detached villas and substantial mansion flats), Knightsbridge (red-brick mansion blocks and stucco terraces) and Earls Court (tall Victorian terraces widely subdivided into flats) — these are the Kensington and Chelsea pockets our drawings cover most. Heritage designations here include Chelsea, Kensington, Holland Park, Ladbroke and Brompton. the Royal Borough of Kensington and Chelsea weighs each proposal against the RBKC Consolidated Local Plan and the Basements SPD, where with the roofscape closely protected, mansard and roof additions are judged against the prevailing profile of each terrace group. Subdivided period houses are common around Earls Court and Notting Hill, and converted flats hold no householder permitted-development rights.. On roofs the borough is concealed butterfly roofs behind the terrace parapets and mansard roofs added to the stucco terraces, over stucco-fronted Georgian and Victorian terraces, purpose-built mansion blocks and mews houses behind the main streets.
Two routes exist and they suit different refusals. A free-go resubmission — a fresh application within twelve months of the refusal, on the same site and in the same description — costs no fee and lets you change the scheme. An appeal keeps the scheme as refused and asks an Inspector to disagree with the Royal Borough of Kensington and Chelsea. Where the refusal reasons are about design detail that can be fixed, resubmission is usually faster; where they are about principle, an appeal is the only route that resolves it.
The decision notice is the brief. Each numbered reason cites policy and states a harm, and the appeal has to meet each one with evidence — sections showing daylight, elevations showing the relationship to neighbours, a site plan proving separation distances. Assertion loses appeals. Kensington and Chelsea is largely stucco-fronted Georgian and Victorian terraces, purpose-built mansion blocks and mews houses behind the main streets, and concealed butterfly roofs behind the terrace parapets and mansard roofs added to the stucco terraces shape what the Inspector will accept as characteristic here.
The borough runs the strictest basement policy in London — broadly one storey deep, under no more than half the garden, with a construction traffic management plan, which frequently appears in refusal reasons and therefore has to be addressed head-on. Almost the entire borough falls within a conservation area, and Article 4 directions strip out permitted-development rights so even minor external changes on the Ladbroke or Chelsea streets need consent.
We give an honest read of the decision notice first. An appeal is usually the right route where:
We take each numbered reason for refusal and answer it with a drawing or an evidenced statement — not with a restatement of the original application. That is the difference between an appeal that reads as a complaint and one that reads as a case.
Below is the Royal Borough of Kensington and Chelsea's real decision record, drawn from official planning statistics and refreshed as new data lands. The Royal Borough grants a fair share of householder applications but under exacting design control, with borough-wide conservation status and its restrictive basement policy the defining constraints. Knowing what this authority actually refuses, and why, is the starting point for deciding whether to appeal or to redesign.

Across Chelsea, Kensington and Notting Hill, the appeals that succeed are narrow and evidenced. They show the daylight test drawn rather than described, they cite the Inspector's own decisions on comparable sites, and they concede the points that are not worth arguing so the case concentrates on the ones that are. An appeal that disputes every reason equally reads as unfocused and usually fails on the strongest one.
With the roofscape closely protected, mansard and roof additions are judged against the prevailing profile of each terrace group. Most householder appeals are decided by written representations, with the Inspector visiting the site unaccompanied. That makes the drawings the primary evidence: what is not on the page is not in front of the Inspector. We prepare the set on that basis, and where the honest answer is that the refusal was sound, we say so and redesign instead.

Three responses to a refusal, with different costs, timescales and prospects.
| Route | Deadline | Typical timescale | Best where |
|---|---|---|---|
| Householder appeal | 12 weeks from the decision | About 8–12 weeks | The refusal turns on principle or a disputed harm |
| Section 78 appeal (other) | 6 months from the decision | Several months | Larger schemes, change of use, new dwellings |
| Free-go resubmission | 12 months from the decision | 8 weeks | The reasons are fixable design detail |
| Fresh application, redesigned | No deadline | 8 weeks | The scheme needs a different approach entirely |
Deadlines from the Town and Country Planning Act 1990, section 78, and the Planning Inspectorate's published appeal procedures.
A process built around the decision notice, because that is what the Inspector reads first.
Send us the decision notice and the refused drawings. We tell you honestly whether the reasons are appealable, whether a resubmission is faster, and how the Royal Borough of Kensington and Chelsea has fared on comparable appeals.
We gather the material that answers each reason — daylight geometry, separation distances, decided appeals on similar sites, and the relevant policies read in full rather than in extract.
We prepare the drawings the Inspector needs and a statement of case that takes each numbered reason in turn, conceding what should be conceded and evidencing the rest.
We lodge the appeal inside the deadline, respond to the council's statement, and revise free until the Inspector issues a decision.
Twelve weeks from the date on the decision notice for a householder appeal, and six months for most other section 78 appeals. The deadline is strict and the Planning Inspectorate will not accept a late appeal, so the first thing we do on a Kensington and Chelsea refusal is check the date and work backwards from it. the Royal Borough of Kensington and Chelsea is the decision-maker.
It depends what the reasons say. If they identify design detail you are willing to change, a free-go resubmission within twelve months costs no application fee and usually resolves faster. If they refuse the principle — that an extension of this type does not belong here at all — only an appeal settles it, because a resubmission would meet the same objection. This applies to your Kensington and Chelsea address specifically. the Royal Borough of Kensington and Chelsea is the decision-maker.
Nationally, a minority of householder appeals succeed, and the ones that do tend to be narrow, evidenced and focused on a single disputed harm. We look at how the Royal Borough of Kensington and Chelsea's refusals have fared at appeal and at comparable decisions nearby before advising, and we will tell you when we think the refusal was sound — an appeal with no prospect costs months.
The scheme itself cannot change on appeal — the Inspector determines the application as refused. What usually needs preparing is evidence: sections showing daylight, elevations showing the relationship to neighbours, and context drawings showing what already exists on the street. Those explain why the refused scheme causes no harm, without altering it. This applies to your Kensington and Chelsea address specifically. the Royal Borough of Kensington and Chelsea is the decision-maker.
In most written-representation appeals, yes — usually unaccompanied, viewing the site from public land and neighbouring property where access is arranged. That is why the drawings matter so much: the Inspector sees the site once, briefly, and everything else comes from the paperwork you submitted. This applies to your Kensington and Chelsea address specifically. the Royal Borough of Kensington and Chelsea is the decision-maker.
Only where the council has behaved unreasonably — refusing against its own officer's clear recommendation without evidence, or failing to substantiate a reason for refusal. Costs awards are the exception rather than the norm, and they are decided separately from the appeal itself. Where the grounds genuinely exist, we make the application alongside the appeal. This applies to your Kensington and Chelsea address specifically. the Royal Borough of Kensington and Chelsea is the decision-maker.
