Party Wall Advice Across Central London
This page covers the common Party Wall issues that arise across Central London, from work to existing party structures to boundary walls and qualifying excavation.
Where we have a more specific borough page, the area links below provide additional local guidance. You can also send us the property address and drawings and we can advise which statutory route is relevant.
What Do You Need Party Wall Help With?
I Am Planning Building Work
Send us the property address and your architectural or structural drawings. We can identify likely notifiable works, affected adjoining owners and the correct notice route before the construction programme depends on neighbour responses.
I Have Received a Party Wall Notice
Send us the notice and drawings. We can explain what is proposed, whether the statutory route appears appropriate and what options you have before deciding 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 instead of each owner choosing a separate surveyor. The surveyor must act impartially under the Act.
When Might the Party Wall Act Apply in Central London?
The Party Wall etc. Act 1996 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. A valid written consent can mean the statutory dispute procedure is not 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 Act does not give Party Wall 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 |
One 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.
Common Party Wall Issues Across Central London
Complex Ownership
Central London projects can involve freeholders, headlease interests and multiple long leaseholders. Ownership should be established before notices are issued.
Basements & Structural Alterations
Deeper excavation, underpinning and structural openings often need detailed drawings and careful statutory administration.
Mansion Blocks & Mixed Use
Party structures can extend beyond walls to separating floors and other structures between separately occupied parts of buildings.
Central London contains extensive listed and conservation-area building stock. Planning, listed-building consent and the Party Wall Act are separate regimes and may all be relevant to the same project.
For Building Owners in Central London
Early Party Wall advice can stop notice requirements becoming a late construction-programme problem. We review the actual drawings rather than assuming that every loft, extension or excavation follows the same statutory route.
- Review of architectural and structural drawings
- Identification of works covered by Sections 1, 2 or 6
- Land Registry ownership checks where appropriate
- Preparation and service of valid Party Wall Notices
- Neighbour response management
- Schedules of Condition where proportionate
- Agreed Surveyor appointments
- Party Wall Awards where a statutory dispute requires one
Received a Party Wall Notice in Central London?
Receiving a notice does not mean you must automatically consent or automatically object. The sensible response depends on the works, the supporting information and the potential effect on your property.
Where appointed as an Adjoining Owner’s Surveyor, our role can include reviewing drawings and structural information, inspecting the property, preparing a Schedule of Condition and agreeing reasonable safeguards within an Award.
A surveyor appointed under the Act acts impartially rather than as an advocate for the owner who selected them.
Schedule of Condition Surveys in Central London
A Schedule of Condition is a written and photographic record of the visible condition of relevant parts of the adjoining property before work starts.
It is not automatically required by the Act, but it can be valuable evidence for both owners if cracking or other damage is alleged later. The scope should be proportionate to the risk: a standard extension may need a targeted record, while a basement or complex excavation can justify a more detailed survey.

Central London 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 will go 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 can 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.

Richard is very responsive and pragmatic and importantly fair to all parties. He is professional and does things timely to ensure there are no delays. He charged a fixed price and needed to deal with multiple garages which created complexity, but he ploughed through and he was able to cut through and inspect the garages to get the party wall award.
Richard is very responsive/supportive, and gets the job done, even in tricky situations like ours.
Excellent experience working with Richard. He was highly knowledgeable, gave clear and practical advice, and made the whole process feel straightforward. What really stood out was his incredibly fast response time, always quick to reply and very easy to work with. Richard took the time to walk us through all our options around the boundary wall, explaining exactly what we could and couldn’t do without unnecessary jargon. His guidance was practical, balanced, and gave us real confidence in how to proceed. Would highly recommend!
Richard Hourican was excellent in handling the party wall matters for our new build. Communication was great throughout and everything was handled efficiently, which made the whole process much less stressful. Would highly recommend!
Richard and his team acted as party wall surveyor on our renovation/extension project in Richmond. They have been on the ball, polite, very good with neighbours (2 out of the 3 neighbours accepted them as surveyors), and efficient at closing out the Awards. The Awards are comprehensive and clear. Fees are very fair.
Richard was a great recommendation and went above and beyond to arrange complex party wall agreements for both sets of neighbours. He worked well with our border team as plans changed and then came together and was highly professional and collaborative. Arranged monitoring and liaised and communicated with everyone smoothly. Would be a great addition to any building project.
Richard was fantastic to work with - very efficient and knowledgeable, and got the work done with minimal fuss.
Richard was excellent to work with, we have 6 partywalls to complete in a short time and he kept us up to date throughout and chased daily to make sure they were done on time.
Geeat experience! Richard engaged with me quickly and communicated well at all stages, making the whole process easy and managing any queries promptly. I'd recommend him
Absolutely brilliant service. H&A assisted us on an urgent basis with a schedule of condition. They were prompt, efficient and extremely professional. The quality of their work speaks for itself. I would highly recommend them.
Richard has been extremely helpful when dealing with my queries about my neighbour extension works even after he was informed that he was not appointed as the party wall surveyor due to some communication issues. A great way to handle such situation professionally.
Highly recommend working with Richard and his team.
