The Partners

What is the Party Wall Act?

The Party Wall etc. Act 1996 came into force in England 1 July 1997.  The act was first introduced after the Great Fire of London in 1666.  

The Act provides owners of building and land certain rights and obligations when undertaking a building project.  The Property Owner undertaking Party Wall works is legally required to notify the Neighbouring Property Owners of the proposed works.   This means the building owner needs the necessary consent prior to commencing works on projects that may affect adjacent buildings, such as rear extensions and basement excavations which are common types of instances where a party wall award may be necessary.

The act aims to prevent neighbour party wall disputes and provide the framework for resolutions to potential issues.

What is a Party Wall?

This is a shared wall separating two properties known as a ‘Party Wall’ within the meaning of the act, including boundary walls and garden walls. These can also be floors separating flats known as ‘Party Structures’.  Examples of construction works requiring a party wall agreement include:-

  • Underpinning, raising or rebuilding the wall
  • To cut away a chimney breast
  • Cutting into the wall for lead work, DPC etc.
  • Chasing walls or floors for pipework or electrics
  • Installing new steel beams into the wall

The steel is usually fixed into the wall on a padstone.  This is effectively where a pocket of the party walls brickwork is cut out to allow a concrete padstone to be formed.  The steel is fixed to the new padstones.

Under Section 2 of Party wall Act 1996 etc Act, party wall notices will need to be served on adjacent properties and permission must be approved prior to starting works.

When excavating within 3 or 6 meters of a neighbouring property, you may be required to serve notice under the Party Wall 1996 etc. Act.

If you are undertaking an extension or excavating within 6 meters of your neighbours’ property or adjoining structures you should seek further advice from a Chartered Surveyor to see if a Party wall award if required.

What is a party wall award?

A party wall award is a legal document between the building and adjoining owner.  Below are some typical examples of what may be included within:-

  • Architects drawings
  • Structural engineers drawings and calculations
  • Schedule of condition
  • Method statements
  • Security of expense
  • Insurance documentation
  • Conditions of undertaking the works
  • Costs

What happens once the Party Wall Works are complete?

Once the works are complete the surveyors will inspect the Adjoining Owner’s property.  They will compare the schedule of condition with the current condition of the property.  Any damages will be noted by the surveyor.

If any damage has been caused by the works these will need to rectify or a financial settlement agreed.

At TD-RE our specialist team can act for Building and Adjoining Owners.  We help ensure it’s a smooth and expedient process for all parties.

Building Owners Guide

If you are undertaking construction works, read our helpful guidance notes.

Any property owner undertaking construction works that fall within the Party Wall 1996 Etc. Act are required to notify their neighbours either one or two month prior to works commencing.  This notice period will depend on the type of works being undertaken.  To produce a sign award which enable works to commence after a statutory period can take longer where construction is more complex.

An ‘Adjoining Owner’ would be classed as anyone with a lease hold interested of of 12 months or longer.

At TD-RE we would recommend  speaking with your neighbour prior to serving any notice advising them of the proposed works and the estimated time periods involved.

Once the Building Owner has served a Party Wall Notice on the Adjoining Owner, they can either consent of dissent to the works.

Neighbours often start to notice cracks and may mistakenly believe these are new and caused by the works.

If a neighbour dissents to the works, they can either appoint their own Surveyor or appoint the same surveyor Acting for the Building Owner.  This known as an “Approved Surveyor” and they must act juristically.

Once the Awards have been agreed by the surveyors, the works can commence after 4 weeks of the award being signed by the Surveyors.

The Building Owner is responsible for paying their Surveyors fee plus reasonable costs of the Adjoining Owners Surveyor.

If you’re planning on. Undertaking works and would like so advice, please contact one of our team who will be more than happy to help.

Adjoining Owners Guide

If your neighbour has served party wall notice on you, read our guidance notes.

More often than not, an Adjoining Owner may only become aware of their neighbours  works when a Notice is delivered by post.  An Adjoining Owner can either consent or dissent to the works.   If the Adjoining Owner does not respond to the Notice within 14 days, then the Adjoining Owner is deemed to dissent to the works.

The Party Wall Award is a legally binding document which sets out to both parties to the award, details of the works, how it will be undertaken and normally drawings and details of how the works can be undertaken to cause minimum unnecessary disruption and protect to the Adjoining Owner.

Below are some typical examples of what might be included within a Party Wall Award:-

  • Any access requirements setting out minimum period of notice
  • Working hours
  • Security of expenses
  • Protection required
  • Any security issues addressed by the erection of scaffolding
  • Protection for dust and debris

In normal circumstances you neighbour will be liable for paying the Adjoining Owners Surveyors fees.  The Surveyor should keep a record of their time spent and have the fees agreed between the two Surveyors.

If you have been served notice by your neighbour please contact one of our team.

Case Studies

Frequently asked party wall questions

The term ‘Party Structure’ is generic and can be defined as a wall or floor.

In this example the floor separating flats is a ‘party structure’ within the meaning of the Party wall act.  In certain circumstances works to this ‘party structure’ will require notices to be issued.  Examples of works are:-

  • Cutting into the structure
  • Chasing into the structure for pipes or cables

If a building owner wants to undertake excavation works within 3 meters of an adjoining owner building is likely to require a Party Wall award.

The proposed excavation works by the building owner will need to extends to a lower level than the bottom of the adjoining owners structure for works to be notifiable under the act.

When your neighbour is within 6 meters of your proposed excavation.  The excavations cut through a diagonal 45 degree from the bottom of the neighbours wall and intersect the newly proposed excavation.   These works will require a Party Wall agreement prior to  commencing construction work.

A schedule of condition records the existing condition of a property.  The schedule forms part of the legally binding Party Wall Award.

Surveyors are normally instructed by each building owner.  The Surveyors will then undertake a independent schedule of condition of the Adjoining Owners Property prior to Party Wall works commencing.  This protects both parties should any damages be caused by the construction work.

Any damages that have been caused can easily be identified by the Surveyors on completion of the works.

The procedure will depend on how quickly your neighbour responds to the initial party wall notice and appoints a surveyor.

In the first instance your neighbour will have up to 24 days to respond to the party wall notice.  Once the notice has been responded to and depending on the complexity of the works it could take between 2 and 8 weeks.

Once a party wall notice is sent your neighbour will have three options: –

  • They can consent to the works and therefore a Party Wall Award is not required prior to commencing party wall works. It would be prudent to still undertake a schedule of condition of your neighbour’s property to protect both your interests, however this is optional.
  • Dissent to the works and instruct an independent surveyor to act on their behalf. Party Wall Award will need to be agree between the two surveyors prior to any notifiable party wall work commencing.
  • Dissent to the works and agree to appoint the same surveyor to act on both you and your neighbour’s behalf known as an ‘Agreed Surveyor.’ Party Wall Awards will still be required prior to commencing notifiable works.

Under the Party Wall Act there are three notices that can be served on your neighbour.  The correct notice will need to be served otherwise this can cause delay and potentially invalidate the Party Wall Agreement.

  • Line of junction Notice – If the works involve building a party wall or party fence on the line of junction. The notice will need to be served a minimum of one month prior to the intended works.
  • Party Structure Notice – If you intent to undertake works to a party wall. The notice will need to be served a minimum of one month prior to the intended works.
  • Notice of Adjacent Excavation – If you are excavating within 3 meters of your neighbours property or 6 meters under certain criteria. You will need a minimum of one months notice.

The Party wall act is there to prevent disputes between neighbours.  Under certain construction works you will need to notify your neighbour of your intended works.

This will allow for a ‘Party Wall Award’ to be agreed prior to any notifiable works commencing.

No, the Party Wall Act states that any notifiable works require prior approval from their neighbours.  Not all construction works require a Party Wall agreement.  If unsure of the correct procedure and need advice about party walls please contact our team at TD-RE.

A ‘building owner’ is the person who wants to exercise their rights under the act and is undertaking construction works.

Under normal circumstances the surveyors fees will be paid by the Building Owner.

This can vary depending on the situation,  construction and complexity of the works.

At TD-RE our Party Wall Specialists aim to make the process as cost effective as possible, a Party Wall Award can cost from as little as £850 Plus VAT.  This is for one Adjoining Owner and us acting as ‘Agreed Surveyor.’

Under the Party Wall Act, the Building owner under normal circumstances is liable to pay for their neighbours surveyors reasonable costs.  The liable fees are only in connection to notifiable party wall works.

Under normal circumstances, 2-3 months.  For more complex works it can take a lot longer and incur further considerable cost.

It is advisable to take early professional advice from someone at TD-RE who will assist with time frames.
