Charterhouse Square (North London News), August 8, 2026. The report states that Islington Council had recently received or validated a range of planning applications, including proposals connected with a commercial building and a protected tree near Charterhouse Square.

The most detailed proposal concerns 25 Charterhouse Square, London, EC1M 6AE. The application seeks permission for the installation of two condenser units at roof level. The application has been given the reference number P2026/1827/FUL.

The available description does not state the size, appearance, screening arrangements or exact position of the condenser units beyond confirming that they would be installed at roof level. It also does not identify the proposed operating hours, noise levels or supporting mechanical equipment associated with the installation.

The application relates to a commercial building rather than a residential property. However, the available report does not provide further information about the building’s current occupier, the purpose of the equipment or whether the proposal forms part of wider refurbishment or servicing work.

A second planning application concerns Suttons Hospital, The Charterhouse, Charterhouse Square, London, EC1M 6AN. The proposal involves works to a Malus domestica tree, understood to be an apple tree, which is protected by Tree Preservation Order 367.

The tree is described in the report as being planted approximately three metres from a building. The application reference is P2026/1906/TRE. The available information does not specify the exact nature of the proposed tree works, such as pruning, reduction, removal of deadwood or another form of maintenance.

Why have the two applications been reported together?

The two applications have been included in the same weekly planning report because both relate to properties in the Charterhouse Square area. One concerns roof-level equipment at a commercial address, while the other concerns works to a protected tree at Suttons Hospital.

Planning applications relating to buildings and trees are considered separately because they involve different planning issues. A full planning application such as P2026/1827/FUL is generally assessed against matters including the impact of the proposed development on the building, neighbouring properties, the surrounding area and any relevant planning policies.

The tree application, identified as P2026/1906/TRE, falls into a different category. Applications involving trees protected by a Tree Preservation Order require the council to consider whether the proposed work is justified and whether it would affect the tree’s health, appearance or contribution to the local environment.

The available report does not say that either application has been approved, refused or withdrawn. Both should therefore be treated as proposals under consideration rather than confirmed developments.

What is known about the roof-level condenser proposal?

The application at 25 Charterhouse Square proposes two condenser units on the roof of the commercial building. Condenser units are commonly associated with heating, ventilation or air-conditioning systems, although the available application summary does not state which building system the equipment would serve.

The report does not provide a technical assessment of the equipment. There is no information in the available material about the units’ dimensions, their position on the roof, the method of installation or whether they would be visible from Charterhouse Square or nearby buildings.

There is also no reported information about potential noise, vibration or visual effects. Those matters may be considered by the council during the planning process if they are addressed in the submitted plans or raised through representations.

The proposal is limited, according to the published description, to the installation of two condenser units at roof level. The available information does not identify any change of use, extension to the building, new floor space or alterations to the public highway.

As with other planning submissions, the council’s assessment will depend on the documents submitted by the applicant and any comments received during the consultation period. The available report does not include a consultation deadline or state whether public comments have been invited.

What is known about the protected tree application?

The second proposal relates to a Malus domestica tree at Suttons Hospital, part of The Charterhouse on Charterhouse Square. The tree is protected under Tree Preservation Order 367.

The report states that the tree is located approximately three metres from a building. That detail identifies the relationship between the tree and the nearby structure, but the available information does not explain whether the proximity to the building is the reason for the application or whether the proposed work is routine arboricultural maintenance.

The application reference, P2026/1906/TRE, indicates that it is a tree-related planning submission. The published summary does not state whether the applicant is seeking permission for pruning, cutting branches, reducing the crown, removing the tree or carrying out another type of work.

Because the tree is protected, work cannot be treated in the same way as ordinary garden maintenance. The council must consider the submitted details before deciding whether the proposed work should be permitted.

No decision or officer recommendation has been reported in the available coverage. The outcome will depend on the council’s assessment of the application and any relevant representations.

Does the report concern Enfield or Islington Council?

The headline supplied with the report refers to planning applications submitted to Enfield Council. However, the article text shown in the available search information states that the applications were submitted to Islington Council.

The locations listed in the article also point to Islington rather than Enfield. Charterhouse Square and The Charterhouse are in central London, while the application references begin with “P2026”, the format used in the available Islington planning information.

The Islington Gazette report specifically describes the items as a summary of planning applications submitted to Islington Council during the previous week. As a result, the council named in the article text and the council indicated by the listed addresses is Islington Council, not Enfield Council.

This distinction is important for residents, businesses and other interested parties because comments must be directed to the correct local planning authority. Enfield Council’s planning register is separate from Islington Council’s planning system, and an application connected with Charterhouse Square would not ordinarily be dealt with through the Enfield planning register.

The discrepancy appears to be in the headline or page labelling rather than in the locations and council description contained in the article information. No evidence in the available material indicates that the two Charterhouse Square applications were submitted to Enfield Council.

How can people follow the applications?

Islington Council’s planning register is the appropriate place to check the status and documents associated with the two applications. Interested parties would normally search using the relevant reference number, address or postcode.

The two references identified in the report are:

• P2026/1827/FUL — installation of two condenser units at roof level at 25 Charterhouse Square, London, EC1M 6AE.
• P2026/1906/TRE — works to a Malus domestica tree protected by Tree Preservation Order 367 at Suttons Hospital, The Charterhouse, Charterhouse Square, London, EC1M 6AN.

The available report does not state the date on which the applications were validated, the consultation closing date or the expected decision date. Those details may be updated on the council’s planning register once the relevant application records and documents are available.

Residents and other interested parties should rely on the official planning records for the current position. The published report confirms that the applications have been identified but does not confirm an approval, refusal or start date for either set of works.

Background to the planning developments

Planning applications allow councils to assess proposed changes to buildings, land and protected features before work proceeds. Islington Council states that planning applications can be viewed and commented on through its online planning register, where documents and application progress are made available for valid applications.

The council’s published planning information also says that, after an application is submitted, an acknowledgement is normally issued within five working days confirming whether the application is valid. Once a valid application has been published, the public can view the application and supporting documents through the register.

The roof-level equipment proposal and the protected tree application are separate matters. The first concerns physical equipment on a commercial building, while the second concerns a tree covered by a protection order. Their inclusion in the same weekly report reflects their location and timing, not a formal connection between the two proposals.

The available information does not establish whether the applications are part of a larger redevelopment scheme at Charterhouse Square. It also does not confirm whether the condenser units would be visible from public areas or whether the proposed tree works are connected to the adjacent building.

Prediction: how could the developments affect local residents and businesses?

If approved, the condenser-unit proposal could lead to limited building works at roof level at 25 Charterhouse Square. The available information does not provide enough detail to predict the duration of installation work, the level of construction activity or the potential effect on nearby occupiers.

Any effect from the tree application would depend on the exact work proposed. If the application involves pruning, the change may be limited to the tree’s appearance and maintenance. If more extensive work is requested, the council would need to consider the effect on the protected tree and the surrounding Charterhouse Square environment.

For local residents, businesses and visitors, the immediate development is the publication and consideration of the two applications rather than confirmed construction. The next significant stages will be the publication of the full application documents, any consultation process and the council’s decision on each reference.

At present, there is no verified information in the available report to conclude that either proposal will cause disruption, alter public access or change the use of the buildings. Those issues can only be assessed once the complete plans, supporting statements and council decisions are available.
