Party Wall Surveyor South East London

Harding Chartered Surveyors advises building owners and adjoining owners across South East London, including Greenwich, Blackheath, Lewisham, Peckham, Dulwich, Bermondsey, Deptford, Brockley, Forest Hill, Catford and Bexley. The area includes Georgian and Victorian terraces, converted houses, mansion blocks, post-war estates and newer infill developments, each presenting different ownership and construction issues.

Party wall requirements should be checked while architectural and structural drawings are being prepared. Whether the Act applies depends on the proposed work, the boundary and neighbouring foundation depths—not simply on the project being called an extension, loft conversion or basement.

When is a Party Wall Notice required?

The Party Wall etc. Act 1996 covers three main categories:

• certain alterations to an existing party wall or party structure, including inserting beams, removing chimney breasts or raising the wall;
• building a new wall at or astride the line of junction; and
• excavating within three or six metres of a neighbouring structure where the statutory depth test is met.

A rear extension is not automatically notifiable merely because it is close to a neighbour. For the three-metre excavation rule, the proposed excavation must go below the level of the neighbour’s foundations. The six-metre test uses a 45-degree line from the bottom of those foundations. Accurate drawings and measurements are therefore essential.

Notice periods and responses

A party-structure notice normally requires two months. Notices for a new boundary wall and qualifying excavation normally require one month. For section 2 and section 6 notices, no written consent within 14 days usually creates a deemed dispute, allowing the surveyor appointment procedure to begin. Section 1 has a different statutory consequence, so silence should not be treated in the same way for every notice.

Notifiable work should not begin before the relevant procedure is complete. Owners should allow time to check titles, identify all adjoining owners and obtain the structural information needed for valid service. Planning permission and Building Regulations approval do not replace compliance with the Party Wall Act.

Our South East London party wall services

Depending on the project and ownership position, we can:

• review architectural and structural proposals;
• identify the adjoining owners who may require notice;
• prepare and serve the correct Party Wall Notice;
• record a written and photographic Schedule of Condition; and
• prepare or agree a Party Wall Award where a dispute has arisen under the Act.

Both owners may appoint one Agreed Surveyor, or each may appoint a separate surveyor. Once appointed under the Act, surveyors must act impartially and determine matters within the legislation rather than advocate for one owner.

Guidance for building owners

South East London projects frequently involve loft steelwork, rear and side-return extensions, basement excavation, underpinning and redevelopment of compact plots. Converted houses and flats can involve several freehold and leasehold interests, so ownership checks should not be left until construction is about to start.

Early advice helps establish which work is notifiable, which neighbours require notice and what information must accompany it. Clear plans and a realistic programme can reduce avoidable disputes and give adjoining owners a proper opportunity to understand the proposals.

Guidance for adjoining owners

A party wall notice is not the same as an application for permission to build. An adjoining owner may consent, consent after practical questions have been answered, or appoint a surveyor where a dispute has arisen under the Act. Before responding, review the proposed structure, foundation depths, access requirements and protective measures.

A Schedule of Condition provides a dated written and photographic record of accessible areas before work starts. Where surveyors are appointed, the Award may regulate the method and timing of notifiable work, inspections, temporary protection, access and the procedure for relevant damage.

An Award cannot decide every boundary dispute, grant planning permission or replace lease consent. It determines matters within the Party Wall Act. Our separate boundary surveying service may be appropriate where the real issue is the position or ownership of the boundary.

South East London property and projects

Greenwich and Blackheath include historic terraces and larger period houses; Peckham, Dulwich, Brockley and Forest Hill contain extensive Victorian and Edwardian housing; Bermondsey and Deptford combine older terraces, converted buildings and dense redevelopment. These differences affect party structures, foundation assumptions and the number of relevant owners.

Common enquiries include steel beams for loft conversions, side-return and rear extensions, chimney-breast removal, basement excavation, underpinning and new walls close to boundaries. In flats and converted houses, freeholders and qualifying leaseholders may both require consideration because shared floors and ceilings can be party structures.

Fees and professional responsibility

Fees vary with the design, number of adjoining owners, access, condition recording and whether an Award is required. The building owner normally pays the reasonable costs of the statutory process, including reasonable adjoining-owner surveyor fees where an appointment is necessary. Costs can be allocated differently when the circumstances justify it.

The Act does not prescribe a particular professional qualification for an appointed surveyor. The government recommends a person with suitable construction knowledge and experience of the legislation. Harding Chartered Surveyors is an RICS-regulated firm, and Jeremy Goldney reviews this guidance.

Independent information is available from the RICS consumer guide and the government explanatory booklet.

South East London party wall FAQs

Does every extension require a Party Wall Notice?
No. The design, boundary position and excavation depth determine whether the Act applies.

Can an adjoining owner stop the work?
The Act cannot be used simply to prevent lawful work. It allows the statutory procedure and appropriate safeguards to be agreed or determined.

Can one surveyor act for both owners?
Yes. Both owners may appoint one Agreed Surveyor. Otherwise, each owner appoints a surveyor and those surveyors select a third surveyor.

Who pays the surveyors’ fees?
The building owner undertaking the work normally pays reasonable costs arising from the statutory process, subject to the circumstances of the case.
