The Planning Applications Committee of Kensington and Chelsea Council met on Tuesday, 23 June 2026, to discuss and decide on a range of planning applications. The committee approved several applications, including window replacements, extensions, and alterations to various properties across the borough. A key decision involved the deferral of an application for an emergency generator at a medical facility due to concerns about its visual impact and potential noise pollution, requiring further information before a final decision can be made.

Emergency Generator Application Deferred

An application for the installation of an emergency generator at a medical facility was deferred pending further information. Councillors expressed concerns about the visual impact of the generator, described as a massive piece of plant, and its proximity to residential properties. While acknowledging the necessity of backup power for the medical facility, particularly for procedures like MRI and CT scans and day surgery operating theatres, the committee sought more clarity on its exact siting, visual screening options, and potential impact on local amenity. Arguments were made that alternative solutions, such as battery backup, should be explored, although the applicant's representative stated that current battery options are not certified for medical use. The decision to defer was made to allow for further investigation into the generator's placement, screening, and overall impact, with the possibility of site visits by councillors.

Window Replacements and Maintenance Approved

Several applications for window replacements and general building fabric maintenance were approved. At 110 Lancaster Road¹, single-glazed timber sash windows were permitted to be replaced with double-glazed units, ensuring they remain timber-framed and white-painted. Similarly, at 275 Ladbroke Grove², located within the Oxford Conservation Area, the replacement of single-glazed timber sash windows with double-glazed units, along with roof tile and rainwater goods replacement, was approved. These works were deemed sympathetic and respectful of the host buildings and surrounding townscape.

Listed Building Consent Granted for Step Repairs

Listed building consent was granted for the repair of historic steps at 1 Pembridge Square³, which serves the Notting Hill Gate Library. The steps were found to be in a dilapidated and dangerous condition, and the proposed repairs, which involve significant reconstruction, were seen as essential for preserving the building's special architectural and historic interest. Conditions were imposed to secure details of the materials and methodology to be used for the repairs.

Extensions and Alterations Approved Across the Borough

A number of applications for extensions and alterations were approved:

• At 41 Sydney Street⁴, internal and external alterations to a basement flat were approved, including the replacement of a metal stair, enclosure of space to form a lobby, and a smaller infill extension at the rear. A separate listed building consent application for the same works was also approved.
• For the house at 41 Sydney Street⁵ (excluding the basement flat), a mansard roof extension, a single-storey extension to the rear closet wing, and a smaller infill extension at ground floor level were approved. These works were considered to preserve the character of the Grade II listed building and the Chelsea Conservation Area.
• At 14 Lansdowne Crescent⁶, permission was granted for an extended basement, new plant equipment, rear fenestration alterations, and landscaping. Despite objections concerning the basement depth and lack of soil above parts of it, the committee found the proposals acceptable, subject to stringent conditions regarding construction management, flood risk, and noise mitigation.
• The Little House, 34 Oxford Gardens⁷, a children's nursery, received approval to vary conditions related to its hours of operation and the use of its outdoor play area. The extended hours, from 07:30 to 18:30 on weekdays and outdoor play from 10:00 to 17:00, were deemed unlikely to cause material harm to neighbouring living conditions, given the established use and previous noise assessments.
• An application to amend approved drawings for 232 King's Road and 18-20 Chelsea Manor Street⁸ was authorised for grant. The amendments included an increase in the height of the Chelsea Manor Street facade, changes to the basement layout, and design modifications to the elevations. While acknowledging concerns about daylight reduction in some neighbouring properties, the committee found the overall benefits of the development, including increased housing stock and improved streetscape, outweighed the identified harm. A legal agreement was required to secure necessary infrastructure improvements.
• At 116-118 Gloucester Road⁹, permission was granted for the temporary display of an externally illuminated scaffold shroud advertisement for a maximum of 12 months. The shroud, featuring a 1:1 static image of the building facade, was deemed acceptable due to its temporary nature and location, with conditions imposed to control illumination levels and hours.
• 28 Moore Street¹⁰ saw approval for a single-storey roof extension, rear and infill extensions, fenestration changes, a roof terrace, plant equipment, and landscaping works. The proposals were found to preserve the character of the host building and the Chelsea Conservation Area.
• 180-186 Brompton Road¹¹ received permission for the installation of an emergency generator in the rear courtyard. The generator, intended solely for emergency medical equipment use, was deemed acceptable subject to conditions managing noise and air quality impacts, acknowledging its infrequent operational necessity.
• At 14 Princes Gate Mews¹², permission was granted for the conversion of a ground floor garage to habitable accommodation, along with window and door replacements, rooflights, and rear elevation alterations. The loss of the garage was deemed acceptable as its dimensions were found to be insufficient for a standard car, and a legal agreement to restrict residents' parking permits was suggested.

Applications Deferred or Refused

• An application concerning an emergency generator at a medical facility on Brompton Road¹³ was deferred. Councillors raised concerns about the generator's visual impact, noise, and air quality, requesting further information and clarification on mitigation measures. The applicant's representative explained that the generator is essential for medical equipment and that battery backup is not currently a viable option for this specific medical use. The committee decided to defer the decision to allow for a more thorough assessment of the generator's impact and potential alternatives.
