Planning to build an extension, convert a loft, or excavate near a neighbour’s wall? If your work affects a shared or adjoining structure, you’ll likely need to comply with the Party Wall etc. Act 1996.
This is where a party wall surveyor becomes essential—especially if disputes arise or your neighbour objects to the work. In this post, we explain how party wall surveyors help resolve disagreements and keep your project on track.
When Does the Party Wall Act Apply?
You must serve a party wall notice if you intend to:
- Build on or near the boundary line
- Work on an existing party wall or structure
- Excavate within 3 or 6 metres of a neighbouring property
These rules cover work like rear extensions, basements, chimney removal, and some loft conversions. Serving the correct notice early can prevent delays later.
What If a Neighbour Objects?
If your neighbour doesn’t consent within 14 days, a party wall dispute is deemed to exist. At this point, both sides must appoint a party wall surveyor to resolve the matter and issue a formal agreement—called a Party Wall Award.
What Does a Party Wall Surveyor Do?
As party wall surveyors, our job is to:
- Interpret and apply the Party Wall Act
- Inspect the properties involved (including taking a schedule of condition)
- Ensure the proposed works are safe and lawful
- Protect both parties’ interests through a fair Party Wall Award
- Remain impartial—even if we are appointed by one side
In some cases, both parties may agree to appoint a Single Joint Surveyor to reduce time and cost.
How We Help Resolve Disputes
Disputes usually arise from concerns over noise, damage, or timing. We manage communication between owners, confirm legal compliance, and record the pre-work condition to avoid arguments later.
If damage occurs, we can refer to the original condition schedule to assess responsibility and agree on repairs.
Why Hire a RICS-Qualified Surveyor?
At Lyman Marshall, we are RICS-regulated and fully experienced in both residential and commercial party wall matters. We ensure every agreement is legally valid and clearly documented—minimising risk to your project.
Whether you’re the building owner or the adjoining neighbour, our surveyors offer guidance every step of the way across Lincolnshire, Nottinghamshire, Humber and South Yorkshire.
Example: Rear Extension in a Semi-Detached Property
A client was building a single-storey extension near a neighbour’s wall. The neighbour objected, worried about subsidence and garden damage. As surveyors, we:
- Served the correct notices
- Inspected and recorded the neighbour’s wall and garden
- Prepared a Party Wall Award with construction safeguards
The neighbour felt reassured, and the build went ahead without dispute.
Thinking About Building Work?
Don’t risk your project getting delayed or legally challenged. Talk to a surveyor before you start work and stay compliant with the Party Wall Act.
