The separate London party wall code ended in 1997

Party wall procedure in London has a different legal history from the rest of the country. Until 1 July 1997, party wall matters in Greater London were governed by Part VI of the London Building Acts (Amendment) Act 1939, not by national legislation. Part VI was repealed with effect from that date by the Party Wall etc. Act 1996 (Repeal of Local Enactments) Order 1997, which repealed the local party wall enactments of only two places in the whole of England and Wales: London and Bristol. Separate transitional provision was made for land in Greater London where Part VI had previously applied.

Only Part VI was repealed. The 1939 Act itself remains in force for other purposes, and several London boroughs still administer applications under it.

Since then the position has been uniform. Section 22(4) of the Party Wall etc. Act 1996 provides that the Act extends to England and Wales only.

Why party wall questions arise often in London

London building stock and density make shared structures and close boundaries common:

802,360 London domestic properties had a recorded build period before 1900, and a further 315,590 a build period of 1900 to 1918, as at 31 March 2025. London has the highest count of pre-1900 properties of any English region. Figures are published by the Valuation Office Agency and are rounded to the nearest ten.
London had 24.52 dwellings per hectare in 2025, against 1.98 for England as a whole. Inner London stood at 51.94 and outer London at 17.53. These MHCLG estimates are provisional.
London district planning authorities decided 24,763 applications for householder developments in the year ending March 2026. MHCLG defines householder developments as those to a residence requiring planning permission, such as extensions, loft conversions and conservatories. The figure is published in live table P124A.

None of this determines whether the Act applies to any particular project. It describes the built environment in which many London projects take place.

Basement work and borough policy

Excavation is where London projects most often engage the notice provisions of the Act. Policy D10 of the London Plan 2021 asks boroughs to establish policies addressing the negative impacts of large-scale basement development beneath existing buildings, noting that high land values and development constraints have led to increasing levels of such development, particularly in central and inner London.

Individual boroughs set their own requirements. The Westminster City Plan, adopted in January 2026, contains Policy 50 on basement developments. The Kensington and Chelsea Local Plan 2024, adopted on 24 July 2024, contains Policy CD11. Camden requires a Basement Impact Assessment, independently audited, and removed some permitted development rights for basements by an Article 4 direction in force from 1 June 2017.

Local planning policy is separate from the Party Wall etc. Act. Planning permission does not remove the need to serve notice, and serving notice does not grant planning permission.

London neighbourhood guidance

Planning authority, conservation status and address-specific controls can change within a named London locality. The first neighbourhood guides cover Party Wall surveyors for Kensington properties, Party Wall surveyors for Acton properties, Party Wall surveyors for Chiswick properties, Party Wall surveyors for Clapham properties, Party Wall surveyors for Fulham properties and Party Wall surveyors for Wimbledon properties. Each keeps the local planning position separate from the statutory notice tests and tells you where an exact address is needed before relying on a council rule.

The next local guides cover Party Wall surveyors for Belgravia properties, Party Wall surveyors for Chelsea properties, Party Wall surveyors for Holborn properties, Party Wall surveyors for Ilford properties, Party Wall surveyors for Knightsbridge properties, Party Wall surveyors for Mayfair properties, Party Wall surveyors for Romford properties and Party Wall surveyors for Walthamstow properties.

Explain the property and proposed work

Whether the Act applies to a London project depends on the actual properties, proposed construction and the distances and depths defined by the Act, not simply the property’s location.

Provide:

the full property address and the London borough;
whether you are carrying out work or responding to a neighbour’s work;
the relationship between the affected buildings or boundaries;
a clear description of the proposed construction, including any excavation depth;
drawings where available;
whether the property is listed or in a conservation area;
notices, responses and correspondence already exchanged; and
known dates and access constraints.

Compare the proposed appointment

Each quote should explain who would appoint the surveyor and the work included. That may involve reviewing drawings, notices, inspections, a schedule of condition, preparation of an award, liaison with another surveyor or later visits.

Under section 10 of the Act, where a dispute arises the parties either concur in appointing a single agreed surveyor, or each appoints a surveyor and those two select a third surveyor. A dispute is deemed to have arisen if an adjoining owner does not respond in writing within fourteen days. The Act does not require a surveyor to hold any particular qualification; it defines a surveyor as any person who is not a party to the matter.

The Party Wall surveyor guide explains when a surveyor may be needed. The Party Wall surveyor cost guide explains the factors that can affect the proposed fee.

Qualified surveyors and documentary checks

RICS members and other appropriately qualified surveyors may quote for Party Wall work through FindTheSurveyor. Each must provide a directly relevant qualification or membership, declare the service, and hold current professional indemnity insurance.

The customer sees the surveyor’s private profile only with that surveyor’s quote. It shows the exact qualification or membership, issuing body, check method and check date, followed separately by the service declaration, contracting identity and insurance status. These documentary checks are not an endorsement or guarantee of the surveyor’s work.

What happens after you post

The administrator reviews each complete enquiry before deciding whether to invite suitable qualified surveyors. Before selection, any invited surveyor receives only the outward postcode and a restricted, non-identifying brief.

If a quote is received and passes the administrative-completeness check, it is shown in the authenticated customer portal with the surveyor’s private documentary profile. Availability varies, so a request may receive several quotes, one, or none. Submission does not guarantee an invitation, quote or introduction.

If the administrator makes an introduction, only that surveyor receives your full contact and property details. FindTheSurveyor charges neither party a fee. You pay the professional fee directly to the surveyor.
