A guide to party walls.

"Party walls" are walls shared between two properties — most commonly the wall between adjoining terrace houses, but also boundary walls and shared garden walls. Works affecting them are governed by the Party Wall Act 1996, which most homeowners only discover when they want to extend, repoint, or alter a chimney. This guide covers what the Act actually requires, when you need professional involvement, and what bricklayer's party wall work costs in 2026.

The Act protects both parties — and getting it wrong (failing to serve notices, ignoring objections) can stop your project and trigger expensive legal action.

What Does the Work Involve?

• Identify whether your wall is a party wall (shared with another property).
• Serve Party Wall Notice on the adjoining owner (typically 2 months ahead).
• Wait for consent or appoint surveyors if dissented.
• Agreed schedule of works and condition surveys.
• Carry out the bricklaying work to agreed standard.
• Re-inspection after work to confirm no damage.

Typical Costs

Party Wall surveyor costs typically apply if your neighbour objects. Many neighbours consent without invoking the formal process.

How Long Does It Take?

• Notice period: 2 months minimum.
• Surveyor agreement (if dissent): 2–8 weeks.
• Actual brickwork: depends on scope.
• Total: typically 3–6 months from notice to work completion.

DIY or Professional?

The legal process can be DIYed (notices, agreements) for amicable situations. The brickwork itself is professional. If your neighbour dissents or you're unsure of your rights, hire a party wall surveyor.

Choosing the Right Tradesperson

• Use a bricklayer with party wall experience — they understand the special handling.
• For complex situations, hire a Party Wall Surveyor (RICS or FPWS certified).
• Document existing condition with photos before work starts.
• Check the bricklayer's insurance covers party wall claims.

UK Regulations

• Party Wall Act 1996 applies to works on/affecting walls shared with neighbours.
• Notice required for: cutting into a party wall, raising a party wall, demolishing and rebuilding, excavating within 3 m and below the foundations.
• Failure to serve notices can lead to injunction stopping work.
• Both parties' rights are protected — you can't unilaterally damage shared structure.

Common Problems

• Cracks from neighbour's works — document existing condition before any party wall work starts.
• Noise complaints during work — agree working hours upfront.
• Disputes about damage — surveyors arbitrate; insurance usually covers.
• Delays from neighbour — Party Wall Surveyors can force movement if neighbour blocks unreasonably.
• Differential settlement after extension — proper foundation tie-ins prevent.
