Measured Building Surveyors in Kensington and Chelsea

Why does a Kensington and Chelsea project need an accurate survey first?

Because almost every address is designated. The borough holds 2,609 listed buildings and 41 conservation areas covering 919 hectares, and it withdrew 20.3% of applications before decision — the highest rate in London. A survey that misreads a party wall or a floor level is expensive here.

What's included

Fully end-to-end in Kensington and Chelsea.

On-site laser survey

A chartered technologist comes to the property with a Leica Disto and a BLK360 scanner. A two- or three-bedroom terrace is normally captured inside 90 minutes, stucco frontages and all.

Existing floor plans

Drawn up in AutoCAD or Revit, at 1:50 or 1:100 as the job requires, to a three-millimetre tolerance. Rooms, openings, fittings and visible services are all annotated rather than implied.

Elevations & sections

All four elevations, plus cross-sections cut through the building. RBKC determined 1,533 listed building consents for alteration or extension between April 2023 and March 2026 and granted 1,401 of them; the applications that struggle are usually the ones drawn without a section. The same drawings then carry a party wall award and the structural design.

3D point-cloud scan

The BLK360 leaves a full 3D point cloud behind it, which is what period fabric demands. Of the 89,250 homes the VOA counted in the Royal Borough in March 2025, 62.6% were already standing before the twentieth century began â€” close to two in three. That is where scanning earns its keep, along with listed buildings and anything geometrically awkward.

Drawing formats

Four formats leave with the job: DWG, RVT, PDF and IFC. Nobody downstream has to convert anything â€” not your architect, not the structural engineer sizing steels, not the contractor pricing the work.

Survey accuracy statement

Every delivery carries an accuracy statement written to RICS convention: three millimetres between any two points, five millimetres worst case across the whole building. Councils accept it, insurers accept it, and so does the party wall surveyor who has to schedule a neighbour's condition off your drawings.

Where in Kensington and Chelsea does a measured building survey actually get determined?

Below: each postcode district we draw in across the Royal Borough, the housing that dominates it, and which council validates the work at that address. The fees listed are statutory England rates for 2026, not our survey prices.

Postcode	Area	Dominant stock	What it means for a measured building survey
SW1X	Knightsbridge / Belgravia	Regency stucco terraces, listed buildings	Knightsbridge / Belgravia is split at SW1X. Either Westminster City Council or RBKC Planning can determine a measured building survey here, so the SW1X address is checked against both policies maps first.
W14	West Kensington / Barons Court	Victorian and Edwardian villas	W14 divides West Kensington and Barons Court between two authorities. A measured building survey there may be determined by Hammersmith & Fulham Council or by RBKC Planning, so the first thing we do with a W14 address is test it against both policies maps.
SW3	Chelsea / Brompton	Georgian and Victorian terraces, listed buildings	A measured building survey at an SW3 address in Chelsea / Brompton is determined by RBKC Planning under its own Local Plan policies for Chelsea / Brompton.
SW5	Earl's Court	Stucco terraces, Edwardian mansion blocks	A measured building survey at an SW5 address in Earl's Court is determined by RBKC Planning under its own Local Plan policies for Earl's Court.
SW7	South Kensington / Knightsbridge	Stucco terraces, mansion blocks, listed buildings	South Kensington / Knightsbridge is split at SW7. Either RBKC Planning or Westminster City Council can determine a measured building survey here, so the SW7 address is checked against both policies maps first.
SW10	West Brompton / World's End	Georgian and Victorian terraces, listed buildings	SW10 runs across the boundary at West Brompton and World's End, which means a measured building survey in that district lands with RBKC Planning on some streets and with Hammersmith & Fulham Council on others. The SW10 policies map settles it street by street.
W8	Kensington	Stucco terraces, listed buildings	Kensington sits wholly inside W8, so RBKC Planning validates every measured building survey submitted from an W8 address.
W10	North Kensington / Ladbroke Grove	Victorian terraces, post-war estates	North Kensington / Ladbroke Grove sits wholly inside W10, so RBKC Planning validates every measured building survey submitted from an W10 address.

Which Kensington and Chelsea neighbourhoods suit a measured building survey best?

Plot depth, wall build-up and the pitch of the roof all shift every few streets here, and each shift alters what a survey can realistically deliver at a given address. A related figure worth knowing: RBKC settles 90.0% of its application decisions under delegated powers, against 97.0% across London, so a much larger share of what comes in ends up argued at committee rather than closed out by an officer.

South Kensington (SW7) — measured building survey work in South Kensington means stucco terraces, mansion blocks, listed buildings. South Kensington is Victorian and Edwardian stucco terraces. Mansion-block surveys here have to record the communal structure as well as the flat throughout SW7.

What local planning policy applies to a measured building survey in Kensington and Chelsea?

Kensington and Chelsea conservation designations: there are 38 across RBKC Planning, Chelsea, Notting Hill, Holland Park among them. Designation costs a Kensington and Chelsea owner the permitted-development route: a measured building survey then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Earls Court is the Kensington and Chelsea designation that most often changes a measured building survey design.

What Article 4 removes near Kensington and Chelsea: Article 4 Directions covering HMOs, office-to-residential, and basement developments — RBKC has some of the strictest basement policies in London. Before pricing a measured building survey we check whether the SW3 address is inside the mapped area, because RBKC Planning draws the Kensington and Chelsea boundary street by street rather than across the whole of Kensington and Chelsea.

Kensington and Chelsea below-ground policy: RBKC's basement policy (post-2015) limits to single-storey under 50% of garden area; double-storey basements effectively prohibited in residential streets. Any measured building survey in Kensington and Chelsea that goes below existing foundations triggers two months notice under section 6 of the Party Wall etc. Act 1996, and RBKC Planning will want the SW3 ground and groundwater position set out.

What Kensington and Chelsea is built from: Grand white stucco Regency and Victorian terraces; red-brick Queen Anne mansions in Kensington; Edwardian mansion blocks; almost no post-war housing stock. Internationally wealthy residents; extensive listed building coverage; heritage and streetscape prioritised in every decision. That mix decides the measured building survey route in Kensington and Chelsea more than the postcode does, and it is what a RBKC Planning case officer reads first. A householder application costs £548 paid to RBKC Planning direct, with 8 weeks to a decision once validated.

Who decides a measured building survey on the edge of Kensington and Chelsea?

Westminster — the Westminster boundary runs against Kensington and Chelsea, so a measured building survey a street from Kensington and Chelsea is decided by Westminster City Council instead. Westminster runs 56 conservation areas across SW1 and its neighbours, which is why measured building surveys priced for Kensington and Chelsea are re-checked against Westminster policy whenever the Kensington and Chelsea address sits on that edge.
Hammersmith and Fulham — cross the Kensington and Chelsea boundary and Hammersmith & Fulham Council takes the measured building survey instead, applying 45 conservation areas of its own around W6. We re-price measured building surveys at the Kensington and Chelsea edge because Hammersmith and Fulham policy and Kensington and Chelsea policy rarely align on measured building survey depth.
Brent — the Brent boundary runs against Kensington and Chelsea, so a measured building survey a street from Kensington and Chelsea is decided by Brent Council instead. Brent runs 22 conservation areas across NW2 and its neighbours, which is why measured building surveys priced for Kensington and Chelsea are re-checked against Brent policy whenever the Kensington and Chelsea address sits on that edge.

Fee follows property size and complexity here, never a clock. Take a two-bedroom terrace as the baseline.
