What is a Section 6 Party Wall Notice?

Section 6: Party Wall Notice Basics

Section 6 of the Party Wall Act concerns excavation works near neighbouring properties. This applies when a building owner plans to excavate or dig within three metres of a neighbour’s foundation and the works extend to a depth lower than their foundations, or within six metres if the excavation intersects the foundation’s 45-degree line. These works can include digging for foundations, basements, or other substructure developments that risk destabilising the neighbour’s property.

Before beginning such works, the building owner must serve a Section 6 notice at least one month in advance. The notice must include details about the excavation, such as its depth, distance from the adjoining property, and the proposed start date. The adjoining owner has 14 days to consent or object. If they object or fail to respond, the dispute resolution process under the Party Wall Act is triggered, requiring surveyors to produce an award. This award will include measures to protect the neighbouring property, such as structural monitoring or additional support during the excavation.

Section 6 ensures that excavation work is planned and executed responsibly, minimising risks to the structural safety of adjoining buildings. It also gives the neighbouring property owner a chance to raise concerns and ensures their interests are protected before any potentially disruptive or damaging work begins.
