London terraced street — typical residential housing for architectural drawings in Kensington & Chelsea

How many listed buildings are there in Kensington and Chelsea?

1,349, of which 18 are Grade I and 116 Grade II*. Only Westminster, with 4,017, and Camden, with 1,968, hold more. Set that beside 41 conservation areas covering 919 hectares and a housing stock of which 62.6% predates 1900 — three times the London share of 20.9% — and the borough is close to comprehensively designated. The practical consequence shows up in a single number: the council recorded 118 lawful development certificates across three years, against 2,336 in Redbridge. In Kensington and Chelsea the question is almost never whether you need consent. It is what consent will let you do.

Answers for Kensington and Chelsea

Does Kensington and Chelsea have listed buildings?

Yes, and more often here than almost anywhere in the country. The borough holds 2,609 listed buildings, concentrated in Kensington, Chelsea, Notting Hill, Holland Park and Earls Court, and consent is needed for any work affecting character, internal or external. The money argument also runs the opposite way from most boroughs: the median local sale during 2025 was £1,195,000 across 1,697 registered transactions, with the upper quartile at £2,250,000 and the median down 3.4% on the year (HM Land Registry Price Paid). Set against figures like those, a properly evidenced application is a rounding error. An enforcement notice on unauthorised work is not.

What's the difference between planning permission and Listed Building Consent?

The two consents ask different questions. Planning permission is about what the outside world sees and how the building is used. Listed Building Consent is about the building itself — its fabric, its features, its character. On a listed address in this borough most schemes need both, and the two run alongside each other rather than one after the other.

How long does Listed Building Consent take in Kensington and Chelsea?

Eight weeks is the statutory clock and it is rarely the real one here. Add a conservation officer, and Historic England wherever the building is Grade I or Grade II*, and 12 to 16 weeks is the honest expectation. The borough issued 1,533 decisions on alterations and extensions to listed buildings over the three-year run of returns closing in March 2026, and granted 1,401 of them: 91.4%, a shade above the 91.2% for the 33 boroughs pooled (MHCLG PS1/PS2, retrieved 1 September 2026).

What's involved in a listed building application?

A detailed measured survey comes first. Then existing-condition drawings, the proposed drawings, a Heritage Statement, a materials specification, and a written justification for every individual change. Photographs of each affected feature go in alongside them, and on a house at this borough's values that photographic record is also what protects you when a future buyer's solicitor asks what was there before.

Can I refuse internal change permission for a listed building?

No. Listing covers the interior as completely as the elevations — plasterwork, joinery, chimneypieces, staircases, doors and their architraves. Take any of it out without consent and the offence is criminal, not a matter of planning enforcement, and the liability attaches to the building rather than to whoever did the work. That becomes your problem on a sale.

Which Kensington and Chelsea postcodes does this listed building consent application service cover?

The Kensington and Chelsea postcode districts we work across, what each of them is mostly built of, and which authority will validate a listed building consent application there. What the table lists are 2026 statutory charges set nationally: not our drawing fee, and not an estimate of what the consented work will cost to build.

PostcodeAreaDominant stockWhat it means for a listed building consent application
SW5Earl's CourtStucco terraces, Edwardian mansion blocksA listed building consent application at an SW5 address in Earl's Court is determined by RBKC Planning under its own Local Plan policies for Earl's Court.
SW7South Kensington / KnightsbridgeStucco terraces, mansion blocks, listed buildingsSouth Kensington / Knightsbridge is split at SW7. Either RBKC Planning or Westminster City Council can determine a listed building consent application here, so the SW7 address is checked against both policies maps first.
SW10West Brompton / World's EndGeorgian and Victorian terraces, listed buildingsSW10 is cut by the borough boundary at West Brompton and World's End, so a listed building consent application from an address here may be determined by RBKC or by Hammersmith and Fulham. We read the address off both policies maps before anything is submitted.
W8KensingtonStucco terraces, listed buildingsKensington sits wholly inside W8, so RBKC Planning validates every listed building consent application submitted from an W8 address.
W10North Kensington / Ladbroke GroveVictorian terraces, post-war estatesA listed building consent application at an W10 address in North Kensington / Ladbroke Grove is determined by RBKC Planning under its own Local Plan policies for North Kensington / Ladbroke Grove.
W11Notting Hill / Holland ParkVictorian stucco terracesNotting Hill / Holland Park sits wholly inside W11, so RBKC Planning validates every listed building consent application submitted from an W11 address.
SW1XKnightsbridge / BelgraviaRegency stucco terraces, listed buildingsKnightsbridge and Belgravia straddle SW1X, where either Westminster City Council or RBKC can turn out to be the determining authority, which is why the exact address is checked against two sets of policies before drawings are prepared.
W14West Kensington / Barons CourtVictorian and Edwardian villasW14 runs across the boundary at West Kensington and Barons Court. Confirm whether Hammersmith and Fulham or RBKC validates your listed building consent application before any W14 drawing package is submitted.

What changes about a listed building consent application in each part of Kensington and Chelsea?

Cornice line, wall build-up and plot depth shift within a single Kensington terrace, and on a listed address each of those differences decides what can realistically be asked for.

Is the council as immovable as its reputation suggests?

On listed building consent, no. On what it takes to get there, yes. RBKC determined 1,533 listed building consent applications to alter or extend across the three years ended March 2026, granting 1,401 of them — 91.4%, which is almost exactly the 91.2% recorded across the London boroughs that decide enough of them to measure. A borough with 1,349 listed buildings is not refusing heritage applications at an unusual rate. What it is doing is refusing the ones that arrive without a proper justification, and taking longer over the rest: only 90.0% of its decisions are taken by officers rather than by committee, the second lowest delegation rate in London against a 97.0% norm.

Where the council does get overturned, it gets overturned hard. Inspectors decided 133 listed building and conservation area appeals from Kensington and Chelsea across the decade ending June 2026, and allowed 53 — 39.8%, against 25.0% for England on the same casework type. That is the widest gap on this measure of any borough in the batch, and it is not an approval rate: only the refused minority appeals. It says that a refusal here is more contestable than the borough's reputation implies, and that the argument is usually about the significance of the heritage asset rather than about the drawings.

Two things designation does not tell you. First, permitted development is largely academic here. The council returned zero larger householder prior approvals in every one of the twelve quarters, which on this return means the figure was not uploaded rather than that none were received, so no refusal rate can be published for the borough at all. Second, its Article 4 directions are not the reason. Of the 2,315 Article 4 areas registered across London, 932 concern the conversion of commercial premises to residential use and 85 concern the householder extension right; none of the 85 is in Kensington and Chelsea, and the register holds no rights record for this borough's areas. What removes permitted development on a Kensington street is listing, or conservation-area designation, or the fact that the building is a flat.

The stock itself is the constraint. Stucco Regency and Victorian terraces, red-brick Queen Anne in Kensington, Edwardian mansion blocks, and almost nothing post-war: 62.6% of the borough's 89,250 dwellings were built before 1900 and just 3.9% since 2010. The largest designations — Holland Park at 73.6 hectares, Oxford Gardens at 67.9, Ladbroke at 64.3, the Royal Hospital at 55.3 — were drawn between 1968 and 1975 around exactly that fabric. A consent application here is scoped against the terrace before it is scoped against the house.

council-ready drawing review · All 33 London boroughs

The national register records 41 conservation areas in the Royal Borough covering 918.9 hectares, where RBKC's own published figure is 38 — the two count designations differently and neither is wrong. Either way listed buildings sit thickly inside them, so most heritage work here is caught twice over: once by designation and once by listing. Listing is not a distance rule: it covers the whole of the building and anything fixed to it, plus any structure within 4 metres of the principal building that pre-dates July 1948. A garden wall can be listed without anyone ever having listed it separately. There is no application fee for listed building consent itself — the council charges nothing to determine it. What costs money is everything around it: if the work also needs planning permission, that is a separate £548 householder application, and a heritage statement is effectively obligatory on a listed building rather than optional. Our drawings start at £840, fixed.
