Question 1

What is a party wall agreement and when do I need one?

Accepted Answer

The **Party Wall etc. Act 1996** governs building work affecting walls and boundaries shared with a neighbour in England and Wales. It is a **legal obligation**, not a courtesy, and ignoring it has real consequences.

**When notice is required:**

**Work on a party wall** — a wall shared between two properties. Cutting into it to insert a beam, raising it, underpinning it, removing a chimney breast, or demolishing and rebuilding it. Two months' notice.

**Building a new wall at or astride the boundary** line. One month's notice.

**Excavating within 3 metres** of a neighbouring structure to a depth below its foundations, or within **6 metres** where the excavation cuts a line drawn at 45 degrees from the base of their foundations. One month's notice. This catches many extensions and basements where no wall is touched at all, and is the provision most often overlooked.

**What does not require notice:** most internal work, replastering, fitting shelves or sockets on a party wall, and work not affecting the structure.

**How the process works.** You serve written notice on the **adjoining owner**, who may:

**Consent** — in writing, and the matter ends there. No surveyor needed.

**Dissent**, or fail to respond within 14 days (which counts as dissent). A **party wall award** must then be prepared by surveyors — either one **agreed surveyor** acting impartially for both, or each owner appointing their own.

The award sets out the work permitted, how and when, records the **condition of the neighbour's property beforehand** through a schedule of condition, and allocates costs. **The building owner normally pays the surveyors' fees.**

**Why compliance protects you too.** The schedule of condition is evidence against later claims of damage you did not cause.

**If you proceed without notice**, a neighbour can seek an injunction halting work, and you lose the Act's protections.

Question 7
