Introduction to Party Wall FAQs

Party Wall FAQs exist because the rules feel technical but the consequences feel personal. Get it right and your project progresses with certainty. Get it wrong and you risk injunctions, delay, and unnecessary cost. The Act sets out a clear process. You serve the correct notice, you wait the statutory period, and you resolve any dispute through surveyors by award. You cannot contract out of the Act and you cannot rely on informal agreements where the Act applies.

The FAQs below cover the questions clients ask before design freezes, before notices go out, and when a neighbour objects. They also address common myths that cause problems on site.

What is a party wall in simple terms

A party wall is a wall that stands on the land of two owners and forms part of a building, or a wall that separates buildings belonging to different owners. The Act also covers party structures such as floors between flats and party fence walls that sit astride a boundary but do not form part of a building. The definitions matter because different notices apply depending on the work and the structure involved.

When does the Party Wall etc. Act 1996 apply

The Act applies to three broad categories of work.

First, work to an existing party wall or party structure. This includes cutting in beams, raising or thickening the wall, underpinning, or demolishing and rebuilding.

Second, building a new wall at the line of junction between two properties. This covers walls astride the boundary or wholly on your land at the boundary.

Third, adjacent excavation. This applies when you excavate within three metres and deeper than a neighbour’s foundations, or within six metres where a 45 degree plane from their foundations is met.

If your work falls into any of these categories, Party Wall FAQs become mandatory reading because notices and timelines apply by law.

Do I always need to serve a party wall notice

You must serve a notice if the Act applies to your work. Consent from your neighbour does not remove the need to serve notice. Written consent after service can avoid a dispute, but service itself remains a statutory requirement. If you start work without serving notice, your neighbour can seek an injunction to stop the works.

What types of party wall notices exist

There are three main notices.

A party structure notice covers works to an existing party wall or structure and requires at least two months’ notice.

A line of junction notice covers new walls at the boundary and requires at least one month’s notice.

A notice of adjacent excavation covers excavations within three or six metres and requires at least one month’s notice, supported by plans and sections.

Each notice has prescribed information. Missing details invalidate the notice and reset the clock.

How much notice do I need to give

Two months for party structure notices. One month for line of junction and excavation notices. These are minimum periods. In practice, you should plan earlier to allow for surveyor appointments and award preparation where a dispute arises.

What happens after I serve a party wall notice

Your neighbour has 14 days to respond. They can consent, dissent and appoint their own surveyor, or dissent and agree to a single agreed surveyor. If they do not respond within 14 days, the law deems a dissent and a dispute arises. Surveyors must then resolve the dispute by award under section 10.

What is a party wall award

A party wall award is a legally binding document prepared by the appointed surveyor or surveyors. It sets out what work you can do, how you must do it, when you can do it, and who pays which costs. It often includes a schedule of condition of the adjoining property and provisions for access, protection, and making good.

Can my neighbour stop my works

Your neighbour cannot veto works that the Act permits, provided you follow the procedure and comply with the award. They can object to the notice, which triggers surveyor resolution. They can also seek an injunction if you fail to serve notice or if you act outside the award.

Who pays the party wall surveyor fees

In most cases, the building owner pays the reasonable fees of all surveyors involved. This reflects the principle that the person benefiting from the works should bear the cost. There are exceptions where works benefit both owners or where repairs arise from shared defects. The award determines costs.

How much do party wall matters typically cost

Costs vary by complexity, location, and risk. Straightforward matters with consent may involve minimal cost. Disputed matters requiring awards and inspections cost more. You reduce cost by serving correct notices early, providing clear drawings, and appointing experienced surveyors who manage risk proportionately.

How long does the party wall process take

Consent cases can complete within weeks, aligned to the notice period. Disputed cases typically take several weeks to prepare an award, depending on information quality and surveyor availability. Appeals must be lodged within 14 days of service of the award.

Can I start work before the award is served

You must not start notifiable works until the notice period expires and any dispute resolves by award. Starting early exposes you to injunction risk and damages.

What is a schedule of condition and why it matters

A schedule of condition records the condition of the adjoining property before works start. It protects both parties. If damage occurs, the schedule provides evidence of pre existing defects. Surveyors almost always include it in an award for higher risk works.

Do minor works require party wall notices

Some minor works do not fall within the Act. Replastering, chasing shallow services, and fixing shelves usually sit outside. Cutting structural beams, removing chimney breasts, and underpinning fall inside. When in doubt, seek advice before assuming an exemption.

Does the Act apply to loft conversions

Often yes. Loft conversions commonly involve cutting beams into party walls, raising party walls, or altering party structures. These works require party structure notices. Party Wall FAQs for lofts regularly focus on steel beam details and weathering to exposed walls.

Does the Act apply to basements and extensions

Yes. Basements almost always trigger adjacent excavation provisions and often party structure works. Rear and side extensions frequently involve excavation within three metres and new walls at the boundary.

What happens if my neighbour refuses access

The Act grants rights of access for notifiable works during usual working hours, subject to notice. If access is refused unlawfully, that refusal can amount to an offence. Awards set access protocols to reduce friction.

Can party wall notices be served by email

Yes, electronic service is permitted where the recipient has stated a willingness to receive notices electronically and provided an electronic address. Without that consent, you must use personal delivery or post.

What if ownership details are unclear

You must serve notice on all adjoining owners. This can include freeholders, long leaseholders, and sometimes tenants with qualifying interests. Land Registry searches and managing agent enquiries reduce the risk of missing an owner.

What if my neighbour is absent or unresponsive

Silence after 14 days creates a deemed dissent. You then appoint a surveyor on their behalf if they fail to appoint within a further 10 days following a request. The process continues.

Can I appeal a party wall award

You can appeal to the county court within 14 days of service. Appeals focus on points of law, not dissatisfaction with surveyor judgment. Courts rarely overturn awards without clear legal error.

Does the Act cover damage and making good

Yes. The building owner must compensate for loss or damage caused by the works. Awards usually require making good or payment in lieu, based on surveyor determination.

Can my neighbour ask for security for expenses

Yes. An adjoining owner can request security before works start. This protects them if works stop or cause damage. Surveyors determine the amount and form of security where parties cannot agree.

Does planning permission remove party wall duties

No. Planning permission and building control approval do not override the Act. Party wall procedures run alongside other consents.

What happens if works change after an award

Material changes require further notice or a revised award. Minor variations may be agreed by surveyors. Starting materially different works without agreement risks breach.

Are party wall matters common in flats

Yes. Floors and ceilings between flats are party structures. Works within one flat often affect another. Notices and awards manage risk in occupied buildings.

What is an agreed surveyor and when to use one

An agreed surveyor acts for both owners where relations are good and risk is manageable. This can reduce cost and time. Each party still retains statutory protection through the award.

Common mistakes highlighted by Party Wall FAQs

Owners start work without notice. Notices omit drawings or dates. Owners assume verbal consent is enough. Owners appoint surveyors too late. These mistakes cause delay and cost. Early advice prevents them.

How to keep the process efficient

Serve correct notices early. Provide clear drawings and method statements. Communicate politely with neighbours. Appoint experienced party wall surveyors. Follow the award on site.

Conclusion - Party Wall FAQs

Party Wall FAQs exist to give you certainty. The Act provides a clear route to build lawfully while protecting neighbours. When you understand when the Act applies, serve the right notice, and follow the award, you reduce risk and avoid delay. If you plan works near a boundary or shared structure, treat Party Wall FAQs as a checklist and act early. That approach saves time, protects relationships, and keeps projects on programme.
