The Party Wall etc. Act 1996 sets out clear rules for building works that could impact neighbouring properties. It applies to both property owners carrying out works and neighbours whose buildings might be affected, providing a fair framework to keep projects moving while protecting everyone’s rights.
This guide walks you through the essentials — from notices and surveyors to awards and dispute resolution.
1. What is the Party Wall etc. Act 1996?
The Party Wall etc. Act 1996 came into force across England and Wales in July 1997. Its main purpose is to:
- Safeguard adjoining properties from potential damage caused by nearby construction.
- Provide a structured process for resolving disputes.
- Allow building work to proceed legally while balancing the interests of all owners.
The Act usually applies to:
- Alterations to shared walls, floors, or ceilings between properties.
- New construction along or near a property boundary.
- Excavations close to a neighbouring building (generally within 3–6 metres, depending on depth).
Ignoring the Act can leave the works unlawful, with the risk of injunctions, disputes, and additional costs.
2. What Counts as a Party Wall?
A party wall is a structure that sits on or across the boundary between two properties. This can include:
- Shared walls separating terraced or semi-detached homes.
- Garden or boundary walls that straddle two plots.
- Floors and ceilings between flats (known as party structures).
Typical projects that fall under the Act include:
- Loft conversions that require inserting beams into a shared wall.
- Extensions built at or near the boundary.
- Basement digs or underpinning.
- Altering the height or thickness of a party wall.
- Cutting into or removing chimney breasts.
- Service runs (wiring, pipes) chased into shared walls.
3. Key Stages in the Party Wall Process
The Act sets out a straightforward three-step procedure:
- Issuing Notices – Informing neighbours of the planned works.
- Schedule of Condition – Recording the state of the neighbouring property before work begins.
- Party Wall Award – A formal agreement that regulates how the work is carried out.
4. Party Wall Notices
The process starts with the Building Owner giving written notice to the affected neighbour(s).
What Should Be Included?
- Names and details of the Building Owner.
- A clear explanation of the proposed works.
- Supporting plans or drawings where available.
- The expected start date.
Timeframes for Notices
- Two months’ notice for alterations to an existing party wall or structure.
- One month’s notice for excavations or new boundary walls.
Types of Notice
- Section 1 – Line of Junction Notice: For new walls built at or near the boundary.
- Section 3 – Party Structure Notice: For works directly affecting an existing shared wall (e.g. loft beams, wall extensions).
- Section 6 – Excavation Notice: For digging works within a set distance (usually 3–6 metres) of a neighbouring foundation.
5. How Neighbours Can Respond
Neighbours (Adjoining Owners) have 14 days to reply. They can:
- Consent – Provide written agreement, allowing works to proceed without surveyors.
- Dissent and Use One Surveyor – Both parties appoint a single, impartial surveyor.
- Dissent and Appoint Separate Surveyors – Each side selects their own surveyor, with a third appointed if necessary.
If no reply is received within 14 days, the law assumes a “deemed dispute”, which means surveyors must step in.
6. The Role of a Party Wall Surveyor
Surveyors are specialists who ensure the Act is followed correctly and disputes are handled fairly. Importantly, they act independently — even if instructed by one of the parties.
Their responsibilities include:
- Advising whether the Act applies.
- Drafting and serving notices.
- Preparing the Party Wall Award.
Surveyor Types
- Building Owner’s Surveyor – Appointed by the party carrying out works.
- Adjoining Owner’s Surveyor – Appointed by the affected neighbour.
- Agreed Surveyor – A single surveyor chosen jointly by both sides.
7. Party Wall Awards
If a dispute arises, surveyors will prepare a Party Wall Award, which is a legally binding document.
An Award sets out:
- How and when the work can be carried out.
- Any protective measures required.
- Rights of access for surveyors and contractors.
- How costs and potential compensation are handled.
This ensures that building work proceeds safely and lawfully, with both parties protected.
8. Managing Neighbour Relations
Neighbouring concerns can often delay or complicate projects. The best way to avoid problems is through early communication and professional guidance.
Benefits of early engagement include:
- Identifying risks before works begin.
- Preventing unnecessary disputes.
- Building trust and goodwill with neighbours.
- Avoiding costly legal action later.
A skilled Party Wall Surveyor helps strike the right balance between enabling development and protecting neighbouring property rights.
9. After the Works
When construction is complete, the surveyor may revisit to check the adjoining property.
- If no issues are found, the process is closed.
- If damage has occurred, the surveyor will arrange for repairs or compensation.
Final Word
The Party Wall etc. Act 1996 is designed to make sure construction projects progress smoothly while giving fair protection to neighbours.
By appointing an experienced Party Wall Surveyor, Building Owners can move forward with confidence, knowing the legal requirements are met and risks are minimised.
