The Party Wall etc. Act 1996 is UK legislation that sets out rights and responsibilities when building work affects a shared wall, boundary, or nearby foundations. It applies in England and Wales and provides a legal process to notify neighbours, resolve disputes, and protect adjoining properties during construction.

The Party Wall Act applies when works affect a shared wall or structure, involve building on or near a boundary, or include excavation close to neighbouring foundations. If your works fall under Sections 1, 2, or 6 of the Act, you must follow the Party Wall process before starting work.

Works requiring a Party Wall Notice include cutting into a party wall, raising or underpinning it, building on the boundary line, or excavating within 3 metres (or 6 metres for deep excavations) of a neighbouring structure’s foundations.

A rear extension usually requires Party Wall compliance if it involves excavation near neighbouring foundations or works to a shared wall. If so, a Party Wall Notice must be served and an agreement or Award reached before construction begins.

Yes. The Party Wall Act commonly applies to loft conversions where structural works affect a shared wall, such as inserting steel beams or raising the wall. A Party Wall Notice is typically required before work starts.

Yes. Basement excavations almost always trigger the Party Wall Act due to the risk to neighbouring foundations. Notices must be served, and a Party Wall Award is usually required before excavation begins.

Yes. The Act applies to flats where floors, ceilings, or walls are shared between different owners. Works affecting party structures require formal Party Wall procedures, even within the same building.

A Party Wall Notice must be served before starting notifiable works. The notice period is usually one or two months, depending on the type of work, and must contain specific legal information.

Most works require at least one month’s notice, while works directly to a party wall or boundary typically require two months’ notice before construction begins.

If you fail to serve notice, your neighbour may seek an injunction to stop the works. You may also be liable for delays, legal costs, and any damage caused, even if the work itself is otherwise lawful.

If a neighbour does not respond within 14 days, they are deemed to have dissented. Surveyors must then be appointed to resolve the matter through a Party Wall Award.

Straightforward cases may take 4–8 weeks. Disputed or complex projects, such as basements, may take several months depending on negotiations and technical issues.

In most cases, the Building Owner carrying out the works pays all reasonable Party Wall surveyor fees, including fees for the Adjoining Owner’s surveyor.

Costs vary depending on complexity, location and risk. Simple matters may cost a few thousand pounds, while complex basement or commercial projects can be significantly more.

Yes. Where works benefit the Building Owner, they are typically responsible for paying reasonable fees for both surveyors appointed under the Act.

Surveyor fees must be reasonable. If costs are excessive, they can be challenged within the Party Wall process or through appeal to the county court.

If a neighbour dissents, surveyors are appointed to agree a Party Wall Award, which sets out how works are carried out and protects both parties’ interests.

The Act allows reasonable access for works authorised by a Party Wall Award. Access must be necessary, properly notified, and carried out with minimal disruption.

A neighbour cannot stop lawful works outright, but they can delay them if proper notices are not served or if the Party Wall process is not followed correctly.

Yes. If works start without complying with the Act, a neighbour may seek an injunction to stop works until proper procedures are followed.

Building Owners must serve valid notices, pay reasonable surveyor costs, protect neighbouring property, and comply with the terms of the Party Wall Award.

Adjoining Owners have the right to be notified, appoint a surveyor, have their property condition recorded, and be compensated for any damage caused by the works.

You should review the notice carefully and either consent, dissent and appoint a surveyor, or agree to a single Agreed Surveyor within 14 days.

Yes. An Adjoining Owner may appoint a surveyor of their choice, with reasonable fees typically paid by the Building Owner.

A Party Wall Surveyor administers the Act, prepares or agrees the Party Wall Award, records property condition, and ensures works are carried out lawfully and safely.

A Party Wall Award is a legally binding document that sets out how works may proceed, including construction methods, access rights, and damage protections.

A Schedule of Condition records the existing condition of neighbouring property before works begin, usually with photographs and notes, to protect both parties if damage is alleged later.

An Agreed Surveyor is a single impartial surveyor jointly appointed by both owners to administer the Party Wall process, often reducing cost and time.

The Act does not require RICS qualification, but many surveyors are RICS accredited, which provides additional professional standards and regulation.

Any damage caused by the works must be repaired or compensated in accordance with the Party Wall Award, usually at the Building Owner’s expense.

Yes. Compensation may be payable for damage, loss, or inconvenience caused by notifiable works, as assessed by the appointed surveyors.

Yes. Appeals can be made to the county court within 14 days of the Award being served, but only on points of law or procedure.

A Party Wall Award usually remains valid for up to 12 months, during which the authorised works must commence.

Many Manchester properties, particularly terraces and Victorian housing, fall under the Party Wall Act. A surveyor is usually required where shared walls or nearby excavation are involved.

Victorian terraced houses commonly share walls and shallow foundations, meaning extensions and loft works frequently trigger Party Wall requirements.

Common mistakes include failing to serve notice, using incorrect notice types, underestimating timescales, and starting work too early.

Delays typically arise from late notices, neighbour dissent, incomplete drawings, or disputes over access and construction methods.

Early communication, clear drawings, accurate notices, and appointing experienced Party Wall surveyors significantly reduce the risk of disputes.

A surveyor should be instructed as early as possible, ideally at design stage, to identify risks, confirm whether the Act applies, and avoid delays.
