Building Survey Kensington and Chelsea: Keep Borough and Locality Evidence Separate

A building survey in Kensington and Chelsea needs the complete address. This page owns the whole Royal Borough boundary. Kensington and Chelsea remain separate locality pages on this site, and neighbourhood names such as Notting Hill can cross or sit within different evidence boundaries. Borough data must not be relabelled as a locality fact or a finding about one property.

FindTheSurveyor is a neutral marketplace. It does not inspect a property, choose the survey level or make a technical finding. A complete verified request may be reviewed administratively without a promised timescale and with no guarantee of an invitation, quote or introduction.

Use the RICS Level 3 survey guide for the national service, the Level 3 survey London guide for regional context and the Level 3 survey cost guide for variables to define in a proposal. None establishes a borough price or property conclusion.

Select scope from the building

RICS describes Level 3 as its most comprehensive Home Survey report and records RICS Building Survey as its former name. Larger, older, altered, unusual or run-down buildings and planned major work are circumstances in which it may be considered, but neither an address label nor a conservation designation selects the service.

The current RICS Level 3 benchmark remains detailed and visual. Permission, safe access and risk of damage limit inspection. Visible services are observed rather than specialist-tested, and an indication of repair costs is additional when agreed. Use the Level 2 vs Level 3 survey comparison to state the required depth and the Level 3 survey example guide to ask how limitations, causes, consequences and recommendations will be reported.

For a house, identify extensions, roof and basement work, removed walls or chimney fabric, drainage changes and access to roof spaces, subfloors, elevations, light wells, drains, gardens and vaults. For a flat or conversion, identify the demise, floor, block position, freeholder or manager and permission for common roofs, façades, basements, plant, grounds and shared drainage.

Read the borough figures as prompts

The exact ONS Census 2021 TS044 result records 66,884 Kensington and Chelsea households. It includes 37,911 in purpose-built flats or tenements, 15,720 in converted or shared houses, 8,561 in terraced houses, 2,064 in semi-detached houses and 767 in detached houses.

The later VOA Council Tax stock release records 89,270 domestic properties at 31 March 2025. Rounded categories include 73,030 flats or maisonettes; its build-period table records 55,850 before 1900 and 2,140 from 1900 to 1918.

ONS counts households at Census Day. VOA counts a later administrative property stock and rounds components. Neither source proves the form, date, alteration history or condition of an address. Use the published mix to prompt questions about tenure, conversions, shared fabric, common access and responsibilities.

Treat basement records as separate evidence sets

RBKC adopted its Local Plan 2024 on 24 July 2024. Policy CD11 addresses basement form, structural stability, nearby buildings and infrastructure, drainage and sewer flooding. The council’s current Article 4 page says the basement direction applies across the borough and came into force on 28 April 2016.

Those controls explain which records may exist; they do not certify the work or present condition. For a basement or light well, seek the decision, approved drawings and conditions; Basement Impact Assessment; chartered engineer’s Construction Method Statement where required; structural and temporary-works design; waterproofing and drainage specification; monitoring; Building Regulations route and completion evidence; guarantees; and repair or ingress history.

Planning permission, Building Regulations evidence, a freeholder consent, a party-wall record, a warranty and the physical survey answer different questions. Record a missing item as unknown rather than assuming that the online file is complete.

Resolve heritage controls at the address

RBKC’s conservation appraisal directory publishes separately adopted material for differently bounded areas. Its property-specific Article 4 schedules can withdraw specified permitted-development rights for identified land or properties.

Do not treat the whole-borough basement direction, a conservation-area direction, a listed status and an appraisal as interchangeable. Confirm the address, map, instrument, affected property class and consent history. Then provide details of visible window, roof, façade, boundary, basement and internal alterations so the proposed inspection can address actual fabric and access.

Build the borough-wide request

Provide the complete address and locality; property form, tenure, floor and block position; approximate age with source; known extensions, conversions, basements, vaults and structural alterations; planning and Building Control records; structural, waterproofing and completion material; exact conservation, listing and Article 4 results; freeholder or management information; access to roofs, subfloors, façades, basements, common parts, grounds and drains; known leaks, damp, cracking, movement or repairs; intended work; and earlier reports.

Submit a Kensington and Chelsea Level 3 survey request with that evidence. Ask each proposal to define the inspection, access assumptions, exclusions, report, timing and separately agreed additions. The marketplace can administer the request but does not provide the survey.
