Every Westminster postcode district we draw in, the stock that dominates it and the authority that validates a planning drawing set there. Westminster fees below are the statutory England rates for 2026, not planning drawing set estimates.
| Postcode | Area | Dominant stock | What it means for a planning drawing set |
|---|---|---|---|
| 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 planning drawing set submitted from an SW1P address. |
| SW1V | Pimlico | Regency terraces, post-war estates | Pimlico sits wholly inside SW1V, so Westminster City Council validates every planning drawing set submitted from an SW1V address. |
| SW1W | Belgravia / Victoria | Regency stucco terraces, listed buildings | A planning drawing set at an SW1W address in Belgravia / Victoria is determined by Westminster City Council under its own Local Plan policies for Belgravia / Victoria. |
| SW1X | Knightsbridge / Belgravia | Regency stucco terraces, listed buildings | A planning drawing set in Knightsbridge / Belgravia may land with Westminster City Council or RBKC Planning — SW1X crosses the boundary, and the SW1X policies map decides it street by street. |
| SW1Y | St James's | Grand Georgian and Regency terraces in Belgravia and Pimlico; Victorian and Edwardian mansion blocks; heritage-rich townhouses throughout; very high listed building density | St James's sits wholly inside SW1Y, so Westminster City Council validates every planning drawing set submitted from an SW1Y address. |
| W1B | Regent Street | Grand Georgian and Regency terraces in Belgravia and Pimlico; Victorian and Edwardian mansion blocks; heritage-rich townhouses throughout; very high listed building density | W1B covers Regent Street only; Westminster City Council handles the planning drawing set, and Regent Street case officers apply the W1B conservation-area map. |
| W1D | Soho | Georgian terraces, mixed-use | Soho sits wholly inside W1D, so Westminster City Council validates every planning drawing set submitted from an W1D address. |
Roof pitch, wall build-up and plot depth change every few Westminster streets, and each one changes what a planning drawing set can achieve at that address.
How designation changes a Westminster planning drawing set: Westminster City Council maintains 56 conservation areas, including Marylebone, Pimlico, Soho. Inside any of them a Westminster planning drawing set cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. St John's Wood sets the tone for Westminster casework.
Westminster and Article 4: Multiple Article 4 Directions — office-to-residential restrictions, HMO conversions, retail to residential in shopping zones. A planning drawing set planned at a NW8 address is checked against that direction first; Westminster City Council publishes the Westminster extent, and the NW8 line rarely follows the Westminster boundary you would expect.
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 planning drawing set 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.
What Westminster is built from: 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. That mix decides the planning drawing set route in Westminster more than the postcode does, and it is what a Westminster City Council case officer reads first. A householder application costs £548 paid to Westminster City Council direct, with 8 weeks to a decision once validated.

Of 119 appeals on new-dwelling schemes decided in Westminster over the window covering appeals decided 2016-2026, Westminster sat close to the London norm, with 26.1% of appeals succeeding against 22.4% city-wide. 31 were allowed and 87 dismissed, with 1 split. Schemes creating a new home - conversions, infills, small developments - carry the most risk, and these 119 Westminster appeals are only the ones refused or left undetermined, never the approvals.
Half of those Westminster appeals took more than 100 days to decide from the day the appeal started — time added on top of the council's own determination period, which is the argument for getting the application right first. 14.3% of them (17 cases) involved a conservation area, so heritage argument carries real weight in Westminster. 87.4% were decided by written representations rather than a hearing or inquiry, meaning the written case and the drawings were the whole of the evidence.

Direct answers to the questions Westminster homeowners ask every week about planning permission drawings.
Start a free quote →Our Westminster planning fee is fixed before we start and depends on the route — a householder application is the simplest, while major works, change of use and flat conversions carry more drawings and supporting documents. Westminster City Council also charges its own statutory application fee on top, set nationally. See our fees for current figures.
Once validated, Westminster City Council aims to decide householder applications within 8 weeks and major applications within 13 weeks — consistent with statutory targets. Our typical end-to-end timeline from instruction to submission is 3–4 weeks.
Yes — Westminster has Article 4 Directions in force. Multiple Article 4 Directions — office-to-residential restrictions, HMO conversions, retail to residential in shopping zones. Article 4 removes specific permitted development rights that would otherwise apply, meaning full planning permission is required where PD would normally be sufficient. We check Article 4 status for your specific property before quoting.
Westminster has 56 designated conservation areas, including Mayfair, Belgravia, Marylebone and others. Planning applications within conservation areas require additional heritage consideration and often a Heritage Statement.
