This guide explains when the Party Wall etc. Act 1996 may apply in Kensington, the main notice routes, the difference between consent and an Award, typical Hourican Associates fees and the local property issues worth checking before work begins.
Party Wall Advice for Kensington Property Owners and Neighbours
Whether the Act applies depends on the construction being proposed, the structures or boundaries affected, the depth of any excavation and the adjoining ownership—not simply whether a project is called an extension, loft conversion or refurbishment.
Early review of architectural and structural information can identify the correct statutory route before the construction programme becomes dependent on neighbour responses.
What Do You Need Party Wall Help With?
I Am Planning Building Work
Send us the property address and architectural or structural drawings. We can identify likely notifiable works, affected adjoining owners and the correct notice route before construction starts.
I Have Received a Party Wall Notice
Send us the notice and supporting drawings. We can explain what is proposed, whether the statutory route appears appropriate and the choices available before you decide whether to consent or appoint a surveyor.
We Would Prefer One Surveyor
Where a statutory dispute has arisen and both owners agree, one impartial Agreed Surveyor may be appointed rather than each owner appointing a separate surveyor. A surveyor appointed under the Act must act impartially.
When Might the Party Wall Act Apply in Kensington?
The Act covers work to existing party structures, certain new walls at the line of junction and qualifying excavation close to neighbouring buildings. The construction details—not simply the project label—determine whether notice is needed.
Work to a Party Wall or Structure
Loft steel, chimney breast removal, cutting into a party wall, raising a party wall and other structural alterations can require a Party Structure Notice under Section 2.
Serving notice does not automatically mean a Party Wall Award is required. If the Adjoining Owner validly consents in writing, the statutory dispute-resolution procedure may not be needed.
Excavation Within 3 or 6 Metres
Within 3 metres, Section 6 can apply where the proposed excavation will go lower than the bottom of the adjoining owner’s foundations.
Within 6 metres, it can apply where the excavation would extend below the statutory 45-degree line drawn downwards from the bottom of those foundations towards the excavation.
Distance alone does not determine whether notice is required.
Building at the Boundary
Section 1 can apply where a new wall is proposed at the line of junction. The procedure differs depending on whether the wall is proposed astride the boundary or wholly on the Building Owner’s land.
The Party Wall Act does not give surveyors power to determine an unrelated dispute about the true legal position of a boundary.
Party Wall Notice Periods
| Proposed work | Typical notice | Minimum notice period |
|---|---|---|
| Work to an existing party wall or party structure | Section 2 Party Structure Notice | Normally 2 months |
| New wall at the line of junction | Section 1 Line of Junction Notice | Normally 1 month |
| Qualifying excavation close to neighbouring foundations | Section 6(1) or 6(2) Notice | Normally 1 month |
A single project can require more than one notice. Section 6 notices must include plans and sections showing the location and depth of the proposed excavation and the proposed building or structure.
Party Wall Considerations in Kensington
Mansion Blocks & Converted Flats
Kensington and South Kensington contain many mansion blocks and converted period houses. Party structures can include separating floors and ceilings as well as walls, while leasehold and freehold interests can mean more than one adjoining ownership needs consideration.
Basements & Lower-Ground Works
Basement and lower-ground projects require particularly careful review of excavation depth, sequencing and neighbouring foundations. Section 6 may apply within 3 metres where excavation goes below the adjoining foundations, or within 6 metres where it crosses the statutory 45-degree line.
Mews, Terraces & Structural Alterations
Mews houses and terraces around Kensington, Holland Park, Earl’s Court and Gloucester Road can involve loft steel, chimney removal, party-wall cutting and boundary work on constrained sites. The correct notice route depends on the actual construction, not simply the project description.
Kensington Basement Planning and the Party Wall Act
The Royal Borough of Kensington and Chelsea gives particular planning attention to basement development, including structural stability of nearby buildings, construction effects such as noise and vibration, traffic and heritage considerations.
Those planning requirements are separate from the Party Wall etc. Act 1996. A basement project may therefore have a planning approval while still requiring Section 6 notices and, depending on the design, notices for work to party structures.
For Party Wall purposes, the excavation drawings, sections, structural details and information about neighbouring foundation levels are especially important. Distance alone does not establish whether Section 6 notice is required.
London Project Evidence
Rather than imply a Kensington appointment where one cannot be verified from the published record, this page links to Hourican Associates’ published London project locations. This keeps the local page factual while allowing prospective clients to review identifiable project evidence.
For Building Owners in Kensington
The best time to check the Party Wall position is while the project information is still being finalised, before neighbour response periods become critical to the build programme.
- Review architectural and structural drawings
- Identify work falling within Sections 1, 2 or 6
- Check relevant ownership information
- Prepare and serve the appropriate notices
- Manage neighbour responses
- Prepare Schedules of Condition where appropriate
- Act as Agreed Surveyor where jointly appointed
- Prepare and agree Party Wall Awards where required
Received a Party Wall Notice in Kensington?
Receiving a notice does not mean you should automatically consent or automatically object. The appropriate response depends on the work, the supporting information and its potential effect on your property.
We can review the notice and drawings, explain the statutory options and, where appointed, consider the condition of the adjoining property and reasonable safeguards relevant to the notifiable works. A surveyor appointed under the Act acts impartially rather than as an advocate for the owner who appointed them.
Schedule of Condition Surveys
A Schedule of Condition records the visible condition of relevant parts of the adjoining property before work starts, normally with written observations and photographs. It is not automatically required by the Party Wall Act, but it can provide valuable evidence for both owners if questions about cracking or damage arise later.
The scope should be proportionate to the works. A straightforward extension may justify a targeted survey, whereas basement or more complex excavation can require a more detailed inspection.
Party Wall Matter or Boundary Dispute?
They are not the same thing.
The Party Wall Act provides procedures for certain work at a line of junction, to a party structure or close to neighbouring foundations. It does not give Party Wall Surveyors authority to decide an unrelated dispute about the precise legal location of a boundary.
If the main question is “where is the legal boundary?”, that issue should be identified separately rather than assuming a Party Wall Award can determine it.
How Much Does a Party Wall Surveyor Cost in Kensington?
We set out the proposed scope and fee before instruction. The final cost depends on the property, works, number of Adjoining Owners and complexity of the appointment.

Kensington Party Wall FAQs
No. If the work is covered by the Act, the relevant notice procedure must be followed, but a Party Wall Award is not automatic. If the Adjoining Owner validly consents, a statutory surveyor appointment may not be required.
Within 3 metres, Section 6 can apply where the proposed excavation goes below the bottom of the adjoining foundations. Within 6 metres, it can apply where the excavation would extend below the statutory 45-degree line drawn downwards towards the excavation from the bottom of those foundations. Distance alone is not enough.
A Section 2 Party Structure Notice normally requires at least two months’ notice. Section 1 Line of Junction notices and Section 6 excavation notices normally require at least one month. Earlier commencement requires the appropriate written agreement where the Act allows it.
Read the notice and supporting drawings before responding. You may consent or, where the Act provides for it, dissent and appoint a surveyor. Hourican Associates can review the documents and explain the options before you decide.
Not exactly. “Party Wall Agreement” is a common phrase. An Adjoining Owner may simply consent in writing to a valid notice. Where a statutory dispute arises and surveyors are appointed, the formal determination is normally a Party Wall Award.
Not through the Party Wall Act. Surveyors can deal with statutory matters arising from works at the line of junction, but an Award cannot determine an unrelated dispute about the true legal position of a boundary.
Not automatically. It is commonly used because it records visible pre-existing condition and can reduce later disagreement about damage. The appropriate scope depends on the property and risk of the proposed work.
Hourican Associates charge £150 + VAT per adjoining owner for the Party Wall Notice service. Standard Schedules of Condition are typically £385–£585 + VAT. Full Party Wall Award appointments are typically £1,100–£1,500 + VAT depending on the property and project. Basement surveys are quoted separately where a more detailed inspection is required.
