Which postcode districts around Westminster do we cover for planning drawing set work?

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.

PostcodeAreaDominant stockWhat it means for a planning drawing set
SW1PWestminster / Vincent SquareGrand Georgian and Regency terraces in Belgravia and Pimlico; Victorian and Edwardian mansion blocks; heritage-rich townhouses throughout; very high listed building densityWestminster / Vincent Square sits wholly inside SW1P, so Westminster City Council validates every planning drawing set submitted from an SW1P address.
SW1VPimlicoRegency terraces, post-war estatesPimlico sits wholly inside SW1V, so Westminster City Council validates every planning drawing set submitted from an SW1V address.
SW1WBelgravia / VictoriaRegency stucco terraces, listed buildingsA 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.
SW1XKnightsbridge / BelgraviaRegency stucco terraces, listed buildingsA 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.
SW1YSt James'sGrand Georgian and Regency terraces in Belgravia and Pimlico; Victorian and Edwardian mansion blocks; heritage-rich townhouses throughout; very high listed building densitySt James's sits wholly inside SW1Y, so Westminster City Council validates every planning drawing set submitted from an SW1Y address.
W1BRegent StreetGrand Georgian and Regency terraces in Belgravia and Pimlico; Victorian and Edwardian mansion blocks; heritage-rich townhouses throughout; very high listed building densityW1B covers Regent Street only; Westminster City Council handles the planning drawing set, and Regent Street case officers apply the W1B conservation-area map.
W1DSohoGeorgian terraces, mixed-useSoho sits wholly inside W1D, so Westminster City Council validates every planning drawing set submitted from an W1D address.

Which Westminster neighbourhoods suit a planning drawing set best?

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.

Does Westminster planning policy restrict a planning drawing set?

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.

Who decides a planning drawing set on the edge of Westminster?

Sources for this Westminster planning drawing set page: borough policies maps and conservation-area registers (2025–26), Royal Mail postcode district boundaries, the Town and Country Planning (Fees for Applications) (England) Regulations, the Town and Country Planning (General Permitted Development) (England) Order 2015 as amended, and the Party Wall etc. Act 1996.

How often do appeals against Westminster succeed?

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.

26.1%of appeals on new-dwelling schemes allowed in Westminster
119appeals decided in the window
100 daysmedian time from appeal start to decision

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.

How much do planning drawings cost in Westminster?

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.

How long does Westminster City Council take to decide planning applications?

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.

Does Westminster have Article 4 Directions?

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.

Which conservation areas are in Westminster?

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.

Do I need a planning consultant for Westminster?

For most householder work in Westminster, a chartered architectural technologist delivers the same planning outcomes as a dedicated consultant — usually at lower cost. Our MCIAT-chartered team handles drawings, submission and agent liaison as one package.

What postcodes in Westminster do you cover for planning drawings?

We cover all Westminster postcodes — SW1, W1, W2, W9, NW1, NW8, WC2 — as well as the immediately adjacent boroughs. Survey appointments are available within 3 working days across Westminster.

How does Westminster's character affect planning applications?

Westminster's grand Georgian and Regency terraces in Belgravia and Pimlico housing stock and 56 conservation areas mean that design quality matters. Westminster City Council officers are experienced reviewers; well-drawn, consistent applications are processed faster than revisions-heavy ones.

Can I appeal a planning refusal in Westminster?

Yes — Planning Inspectorate appeals are available as a right within 12 weeks of refusal from Westminster City Council. Written representations take 16–20 weeks; hearings 24–32 weeks. We prepare appeal statements and revised drawings for cases where refusal was on design or policy grounds.
