The Three Types of Party Wall Notice

Different building works trigger different notices. Understanding which applies to your project is critical — many projects trigger more than one.

New Wall at the Boundary

⏱ 1 Month Notice Required

Applies when you are building a new wall at or astride the boundary line. This notice concerns the position of the new wall itself, including cases where the adjoining owner may have options around contribution or underpinning.

  • Building a new wall on the boundary line
  • Constructing a new wall astride the boundary (with consent)
  • Certain side or rear extension boundary walls

Works to an Existing Party Wall

⏱ 2 Months Notice Required

The most common notice in London renovations. Required when works affect an existing shared wall or party structure — particularly relevant for loft conversions and structural alterations in Victorian and Edwardian terraces.

  • Cutting beams or steels into a party wall
  • Removing or supporting a chimney breast
  • Underpinning, thickening or raising a party wall
  • Opening rear rooms affecting the shared wall

Excavation Near Neighbouring Structures

⏱ 1 Month Notice Required

Required when excavating within 3 to 6 metres of a neighbour's structure and digging deeper than their foundations. This is where London kitchen extensions frequently trigger party wall obligations even when no shared wall is touched.

  • Excavating for new extension foundations within 3m
  • Basement excavations near neighbouring structures
  • Any dig going deeper than a neighbour's foundations

What Is the Party Wall etc. Act 1996?

The Party Wall etc. Act 1996 is an act of parliament that legally requires anyone proposing to carry out certain types of work to their property to formally notify the owners of neighbouring properties before commencement. It provides a clear framework enabling building owners to carry out notifiable works while giving adjoining owners a defined process for understanding what is proposed and protecting their property.

Where works fall within the scope of the Act, it is necessary for the Building Owner to serve the correct notice(s) and obtain written consent from the Adjoining Owner. If consent is not given — or is not forthcoming — the parties are deemed to be 'in dispute' under the Act. At this point, both the Building Owner and the Adjoining Owner must appoint a Party Wall Surveyor. The dispute is then resolved by way of a Party Wall Award — the legal framework that enables the works to proceed whilst protecting both parties.

1

Alterations to Existing Shared Walls or Structures

Shared walls (party walls) and party structures — which may include floors as well as walls — require notice before any structural alteration is made.

2

New Walls Up To or Astride the Boundary

Construction of new walls either up to or astride the boundary line (with the neighbour's consent) must be formally notified under the Act.

3

Excavation Close to Neighbouring Properties

Digging within three metres of a neighbouring wall or shared structure — including new extension foundations — may trigger the Act regardless of which side of the boundary the work sits.

Common Questions

Frequently Asked Questions

Do I need a party wall surveyor?

If your proposed works fall within the scope of the Party Wall etc. Act 1996 — and your neighbour does not consent in writing — then yes, a party wall surveyor must be appointed by law. Even where consent is given, a surveyor can protect your interests with a Schedule of Condition.

What happens if I ignore the Act?

Non-compliance can result in an injunction from the High Court, project delays of six months or more, and legal costs exceeding £10,000. It can also damage your relationship with your neighbours and complicate any later sale of your property.

How long does the process take?

The minimum notice periods are one month (Sections 1 and 6) and two months (Section 2). In practice, with a dissent or no response, disputes requiring a Party Wall Award can add 8 to 12 weeks to your programme, which is why early notice is essential.

What is a Schedule of Condition?

A Schedule of Condition is a detailed photographic and written survey of an adjoining property taken before works begin. It establishes a clear baseline — protecting both the building owner from unfounded damage claims and the adjoining owner if genuine damage does occur.

Can both parties use the same surveyor?

Yes. This is called an Agreed Surveyor arrangement. Both parties appoint a single surveyor who acts impartially for both sides. It is often the quickest and most cost-effective route — particularly where the relationship with your neighbour is good.

My neighbour has received a notice — what should I do?

You have 14 days from receipt to respond. You can consent in writing, dissent and appoint your own surveyor, or agree to an agreed surveyor. If you do nothing within 14 days, a dispute is automatically deemed to have arisen. Contact us immediately for free initial advice.

Does a rear extension require a party wall notice?

Frequently yes — even if the extension is entirely within your own land. If the new foundations are within 3 metres of a neighbouring structure and go deeper than their foundations, an Adjacent Excavation Notice is required under Section 6 of the Act.

Who pays the surveyor's fees?

In most cases, the Building Owner (the person carrying out the works) pays the reasonable fees of both surveyors. The Act makes provision for this, and costs can vary depending on the complexity of the project and the extent of works.
