The Party Wall Act
01What is the Party Wall Act, and does it apply to my project?The Party Wall etc. Act 1996 provides a procedure for certain building work affecting shared structures, boundary walls or nearby foundations. Your project needs checking against the work described in the Act, not simply against whether it is called an extension, loft conversion or basement.02Party wall, party fence wall, party structure: what counts?A party wall can stand across a boundary or stand on one owner's land while separating different owners' buildings. A party fence wall is a qualifying freestanding boundary wall, while a party structure can include a floor or other structure separating separately accessed parts of a building.03The three types of notice: new wall on the boundary, work to a party wall, excavation near a neighbourThe three main notice routes concern a new wall at the boundary, work to an existing party structure, and excavation close to a neighbour's foundations. The usual minimum notice is one month for boundary-wall and excavation work, but two months for a party structure notice.04The 3m and 6m excavation rulesExcavation may need notice if it is within 3m of a neighbour's building or structure and below its foundations, or within 6m and reaches the Act's downward 45-degree foundation plane. Distance alone is not enough: the relevant foundation levels and excavation depth must also be established.05Which works don't need a notice?Minor surface work such as putting up ordinary shelves, replastering or replacing electrical wiring and sockets does not normally require a party wall notice. The exemption is not based on the job's price or duration: work involving a qualifying structural alteration, boundary wall or excavation must still be checked.06When to serve notice: timing against planning, building control and the start on siteServe party wall notices early enough to allow the statutory notice period and any necessary dispute resolution before the affected work starts. Planning permission does not have to be granted before notice is served, but the proposed work must be sufficiently defined for the notice to describe it properly.07Can I serve the notices myself?Yes. A building owner can prepare and serve their own party wall notices; the Act does not require a surveyor merely to send a notice. However, the correct owners, statutory route, work details and service method must be identified, and a dispute may require surveyor appointments.08My neighbour's options: consent, dissent, counter-noticeYour neighbour can give written consent, dissent so that a dispute is resolved by surveyors, or in appropriate party-structure cases serve a counter-notice requesting specified additional work. These are different responses, and the options depend on which statutory notice you have served.09What if my neighbour doesn't respond?For a party structure or adjacent-excavation notice, no written consent within 14 days normally means a dispute is deemed to have arisen, not that permission has been given. New-boundary-wall notices under section 1 follow different rules, so first check exactly which notice was served.10Agreed surveyor, two surveyors, third surveyorWhere a party wall dispute needs surveyors, both owners can appoint one agreed surveyor, or each can appoint a surveyor and those two select a third. The surveyors perform a statutory, impartial role: paying a surveyor does not make the award a decision in your favour.11Who pays the surveyors, and what does it cost?For work benefiting the building owner, that owner will normally pay the reasonable party wall surveyor costs, including the adjoining owner's reasonable surveyor costs where an award is needed. The Act does not set a standard fee or make the building owner responsible for every amount another person chooses to charge.12Schedule of condition: why it protects both sidesA schedule of condition records the visible condition of relevant parts of a neighbouring property before work starts. It gives both owners a baseline if damage is later alleged, although preparing one is not itself a requirement of the Party Wall etc. Act 1996.13The party wall award: what it contains and how to appeal itA party wall award is the surveyor's or surveyors' written determination of a dispute under the Act, setting out matters such as the authorised work, timing, method and costs. Either party can appeal to the county court within 14 days beginning with the day the award is served on them.14Access to the neighbour's land and scaffolding over the boundaryThe Party Wall etc. Act can provide access to neighbouring land where it is necessary for work covered by the Act, subject to its conditions and notice requirements. It does not give a general right to use the neighbour's garden or airspace for all parts of a building project; scaffolding outside that right needs a separate lawful arrangement.15If the works damage the neighbour's propertyThe building owner must compensate an adjoining owner or occupier for loss or damage resulting from work carried out under the Party Wall etc. Act. If damage appears, record it promptly, notify the building owner and the appointed surveyor where there is one, and establish the cause and remedy rather than assuming every new defect has the same explanation.16Starting work without a notice: the consequencesStarting notifiable work without the required party wall procedure can expose the building owner to an injunction, damage claims and avoidable legal costs. Planning permission does not cure the omission, and a document described as a retrospective party wall award is not a universal way to regularise what has already happened.
Neighbours and planning
17Should I show my neighbours the plans before applying?Yes, showing neighbours a clear version of the proposal before applying is usually a useful way to identify concerns while changes are still possible. It is not a substitute for formal consultation, a party wall notice or any separate consent needed to use their property.18What if my neighbours object?A neighbour's objection does not automatically stop a planning application. The council must assess the relevant planning effects against the development plan and other material considerations; agreement or disagreement between neighbours is not a substitute for that assessment.19Right to light: can a neighbour challenge my extension?Yes. A neighbour with an enforceable private right of light may be able to challenge an extension which infringes that right, even where planning permission has been granted. This is a separate legal issue from the council's assessment of daylight, sunlight and neighbouring amenity.20Overlooking, privacy and overbearing impactCouncils assess whether a proposal would cause unacceptable harm to neighbours through overlooking, loss of privacy or an overbearing form. The assessment depends on the actual relationship between buildings, windows and outdoor spaces, together with the applicable local policies; a single quoted separation distance does not decide every site.21Building on or near the boundary, and boundary disputesBuilding close to a boundary does not by itself establish a right to put walls, foundations or scaffolding on neighbouring land. Confirm the legal boundary, assess the planning and party wall requirements, and resolve any disputed land or access rights before the design relies on them.22My neighbour is building: how to comment or objectCheck the council's planning register, read the current application drawings and submit comments through the council's stated route before the deadline. Explain the planning effect on your property with specific evidence; contacting the applicant or discussing the matter informally is not a substitute for sending your comments to the authority.23My neighbour built without permission: what can I do?Check whether the work actually needed planning permission and whether it matches any approval before reporting a suspected breach to the council's planning enforcement team. No visible application does not prove a breach, and enforcement action is a matter for the authority's proportionate assessment rather than an automatic consequence of a complaint.
