Get your party wall notices and surveying handled properly

For homeowners in England and Wales building next to a neighbour, and for neighbours who’ve received a notice. Explain the work and compare quotes from party wall surveyors.

The Party Wall etc. Act 1996 sets out a procedure, in England and Wales, for work that affects a shared wall, a wall on the boundary or a neighbour’s foundations. Common triggers are cutting steel beams into a party wall for a loft conversion, building a new wall on the boundary for an extension, and digging foundations or a basement close to next door. A party wall surveyor works out which notices are needed, serves them on every owner, records the condition of the neighbour’s property before work starts and, if the neighbour doesn’t consent, agrees formal terms for how and when the work is done. Surveyors appointed under the Act must act impartially, even when chosen by one side.

How a professional can help

• Working out which notices you need: Reviewing your drawings and structural design to see whether the work affects a party wall, involves building on the boundary or excavating near a neighbour’s foundations.
• Preparing and serving notices: Drafting notices with the right content and drawings, serving them on every owner of the neighbouring property, including freeholders and leaseholders of flats, and tracking response periods.
• Schedules of condition: Recording the condition of the neighbour’s rooms, walls and ceilings with notes and photos before work starts, so any later damage claim can be judged against a clear record.
• Agreeing terms when there’s a dispute: Drawing up the formal document under the Act, often called a party wall agreement, covering working hours, access, protection, method of work and how any damage is made good.
• Acting for the neighbour: If you’ve received a notice, a surveyor can check the proposed work, explain your options and act for you, so your property is protected while next door builds.
• Damage during or after the work: Inspecting reported damage, comparing it with the schedule of condition, and deciding how it should be repaired or compensated under the terms agreed.

Is this right for you?

• You’re planning a loft conversion, extension or basement in England or Wales and share a wall or boundary with a neighbour.
• Your structural engineer’s design puts beams into the party wall or needs deep foundations close to next door.
• You’ve received a party wall notice and don’t know whether to consent, dissent or appoint a surveyor.
• Your neighbour has started work without serving notice and you’re worried about your home.
• You want a clear record of your neighbour’s property before building starts, even if they’re happy to consent.

How the project usually runs

• Review the proposed work: The surveyor studies the drawings, structural design and site to identify party wall, boundary and excavation work, and which neighbouring owners need notice.
• Serve the notices: Notices are served well ahead of the planned start, because the Act sets minimum notice periods for each type of work, and neighbours then have a set time to respond.
• Consent or appointment of surveyors: If neighbours consent in writing, work can go ahead under the notice. For most notices, if they dissent or don’t reply in time, a dispute is treated as arising, and either one agreed surveyor or a surveyor for each owner is appointed.
• Schedule of condition and formal terms: The surveyors inspect and record the neighbour’s property, then set out the agreed terms covering the work, timing, protection and access in a formal document both owners receive.
• Works and final inspection: Building goes ahead under the agreed terms. Afterwards, the surveyors revisit the neighbour’s property, compare it with the schedule of condition and deal with any damage.

What affects the cost

• How many neighbouring properties and owners are affected, including freeholders and leaseholders in flats.
• Whether neighbours consent, or a dispute means surveyors have to agree formal terms.
• Whether one agreed surveyor acts for both sides or each owner appoints their own.
• The type of work, such as a single steel beam compared with a basement excavation.
• The size of the neighbour’s property that needs recording in the schedule of condition.
• Any extra inspections, damage claims or design changes after notices have been served.

The Party Wall etc. Act 1996 and where it applies

• The Act applies in England and Wales only. Scotland and Northern Ireland have no direct equivalent, so take local advice there.
• Planning permission and Building Regulations approval don’t remove the need to serve party wall notices.
• The Act sets minimum notice periods that differ by type of work, so build them into your programme early.
• The Act isn’t a way to settle boundary disputes or rights of light questions, which need separate advice.

Questions people ask

Do I need a party wall surveyor for a loft conversion?

Most loft conversions in terraced and semi-detached houses involve cutting into the party wall for steel beams, or building it up, so notice is usually needed in England and Wales. You don’t have to use a surveyor to serve notice, but many people do to get it right. If the neighbour dissents, surveyors must be appointed.

Can I serve a party wall notice myself?

Yes. The Act doesn’t require a surveyor to serve notice, and government guidance includes example notices. But a notice with missing information, or one not served on every owner, may be invalid, which can delay the job. A surveyor makes sure the right notices reach everyone who needs them.

Who pays for the neighbour’s surveyor?

Usually the building owner, meaning the person having the work done, pays the reasonable costs of both surveyors, because the work is for their benefit. The surveyors decide costs as part of the formal terms, and they can share them differently in some situations, for example where a neighbour asks for extra work.

What happens if my neighbour doesn’t reply to the notice?

For most notices, if a neighbour doesn’t respond within the period allowed, a dispute is treated as having arisen. A surveyor then needs to be appointed for them, and the Act has a process for doing this if they still don’t engage. Your surveyor can guide you through it.

What is a schedule of condition?

It’s a written and photographic record of the neighbour’s property, usually the rooms and walls nearest the work, made before building starts. If cracks or damage are reported later, it shows what was already there, which protects both owners from unfair claims.

My neighbour started work without serving notice. What can I do?

Talk to them first, as they may not know about the Act. If work carries on, a party wall surveyor can explain your options and what the Act requires of them. In some cases neighbours seek legal remedies through the courts, so take professional advice quickly.
