More than a third of every listed building consent decision made in London is made here. What that concentration means for your application, what Westminster’s conservation team wants to see drawn, and where the consent process differs from planning permission.
Very often, and usually favourably. Westminster decided 4,689 listed building consent applications to alter or extend in the twelve quarters to March 2026 — 37% of the 12,584 decided across all 33 London boroughs, and more than three times the next busiest, Kensington and Chelsea at 1,533. It granted 92.2% of them, a shade above the London figure of 91.2%. So the difficulty in this borough is not persuading a council unfamiliar with listed fabric; it is meeting the standard of a team that sees this work every week.

In detailCheck the entry rather than assume either way. There are 4,017 listed buildings inside this borough — 205 at Grade I, 373 at Grade II*, 3,418 at Grade II and 21 whose grade is not recorded (Historic England data via the Planning Data Platform, retrieved 2 September 2026) — so the density here is unlike anywhere else in the country and the answer surprises people in both directions. Two questions decide it. First, whether the building itself is listed, which you confirm from the National Heritage List for England and not from the estate agent's particulars. Second, whether what you propose affects its special interest — a test that catches internal work, outbuildings and anything fixed to the structure, not only what shows from the street. Consent is separate from planning permission, and you frequently need both.
They ask different questions of the same drawings. Planning permission asks what your proposal does to the street and to the neighbours: bulk, overlooking, use, appearance from the public realm. Listed building consent asks what it does to the building's own special architectural or historic interest, right down to a cornice or a run of original joinery. A rear extension on a listed townhouse typically needs both, and they can be decided differently, so the safe assumption is that you are running two applications in parallel rather than one with a longer form.
Plan for three to four months rather than the statutory eight weeks. Grade I and Grade II* proposals go to Historic England as a matter of course, which adds a consultation stage the council does not control. The wider Westminster record supports a cautious estimate: across all its householder work the council determined only 74.5% of applications inside eight weeks in the twelve quarters to March 2026, where London managed 92.5%, and it agreed a formal extension of time on just 26.5% of decisions. In other words the extra weeks here tend to arrive unannounced rather than as a date you agreed (MHCLG planning statistics, retrieved 1 September 2026).
A measured survey accurate enough to argue from, existing and proposed drawings at matching scales, a schedule of works item by item, a heritage statement, a materials and finishes specification, and photographs of every feature the work touches. The item most often missing is the justification: a case officer needs to read, for each individual change, what is being removed, what replaces it, and why the building's interest survives the swap. A general statement that the scheme is sympathetic will get the application validated and then stalled.
No, and this is the misunderstanding that causes the most trouble in Westminster's Georgian and Regency stock. The listing covers the whole building, inside and out, together with anything fixed to it and often the structures around it. Plaster cornices, panelled doors, original staircases, fireplaces and the pattern of the internal walls are all protected fabric. Carrying out work without consent is a criminal offence rather than a planning breach, which means it does not become lawful with the passage of time, and it will surface on the next sale.



Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.
Where the listed stock actually sits, district by district, and which council you file with when a district straddles a boundary. Note that a listed building consent application carries no council fee of its own; the statutory England rates quoted for 2026 apply to any planning application running alongside it, and neither figure is our fee for the drawings.
| Postcode | Area | Dominant stock | What it means for a listed building consent application |
|---|---|---|---|
| NW8 | St John's Wood | Victorian villas, mansion blocks | St John's Wood is split at NW8. Either Westminster City Council or Camden Council can determine a listed building consent application here, so the NW8 address is checked against both policies maps first. |
| SW1A | Whitehall / Buckingham Palace | Grand Georgian and Regency terraces in Belgravia and Pimlico; Victorian and Edwardian mansion blocks; heritage-rich townhouses throughout; very high listed building density | SW1A covers Whitehall / Buckingham Palace only; Westminster City Council handles the listed building consent application. |
| SW1E | Victoria | Regency terraces, post-war flats | A listed building consent application at an SW1E address in Victoria is determined by Westminster City Council under its own Local Plan policies for Victoria. |
| SW1H | St James's Park | Grand Georgian and Regency terraces in Belgravia and Pimlico; Victorian and Edwardian mansion blocks; heritage-rich townhouses throughout; very high listed building density | A listed building consent application at an SW1H address in St James's Park is determined by Westminster City Council under its own Local Plan policies for St James's Park. |
| SW1P | Westminster / Vincent Square | Grand Georgian and Regency terraces in Belgravia and Pimlico; Victorian and Edwardian mansion blocks; heritage-rich townhouses throughout; very high listed building density | Westminster / Vincent Square sits wholly inside SW1P, so Westminster City Council validates every listed building consent application submitted from an SW1P address. |
| SW1V | Pimlico | Regency terraces, post-war estates | SW1V covers Pimlico only; Westminster City Council handles the listed building consent application. |
| SW1W | Belgravia / Victoria | Regency stucco terraces, listed buildings | SW1W covers Belgravia / Victoria only; Westminster City Council handles the listed building consent application. |
| SW1X | Knightsbridge / Belgravia | Regency stucco terraces, listed buildings | Knightsbridge / Belgravia is split at SW1X. Either Westminster City Council or RBKC Planning can determine a listed building consent application here, so the SW1X address is checked against both policies maps first. |
Forty-four per cent of the 132,190 homes in this borough were built before 1900, against 20.9% across London (VOA council tax stock, 31 March 2025). What that average conceals is how sharply the fabric changes street by street — lath and lime in one terrace, early cavity work a few hundred metres away — and a consent case is won or lost on getting that right in the survey.
Conservation areas covering Westminster: Westminster City Council runs 56, and St John's Wood, Mayfair, Belgravia are the ones Westminster owners meet most. A listed building consent application inside a Westminster conservation area loses permitted development, so the Westminster submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Soho a listed building consent application is judged on the street elevation first.
Article 4 and your Westminster listed building consent application: Multiple Article 4 Directions — office-to-residential restrictions, HMO conversions, retail to residential in shopping zones. At a NW8 address that matters twice over, because Westminster City Council applies the direction unevenly across Westminster — we read the Westminster policies map for the exact NW8 address before quoting listed building consent applications.
Westminster below-ground policy: Westminster basement policy restricts to single-storey, typically under 50% of rear garden footprint; lightwells and rooflights strictly controlled in conservation areas. Any listed building consent application in Westminster that goes below existing foundations triggers two months notice under section 6 of the Party Wall etc. Act 1996, and Westminster City Council will want the NW8 ground and groundwater position set out.
The building fabric around Westminster: Grand Georgian and Regency terraces in Belgravia and Pimlico; Victorian and Edwardian mansion blocks; heritage-rich townhouses throughout; very high listed building density. Heritage-first planning approach; listed buildings on almost every street; basement and rear extension policies particularly strict. A listed building consent application in Westminster is scoped against that stock first.

Westminster holds more listed buildings than any other London borough by a wide margin, and issues more certificates of lawfulness for listed-building works than the rest of London combined.
