What is the process?
Service of Notices

If you are carrying out works that fall within the remit of the Party Wall etc. Act 1996 then you or your Surveyor (known as the Building Owner's Surveyor), are required to serve Notice to your Adjoining Owners outlining your intentions. 

Works that fall under the Act include works that affect an existing party wall or structure, construction of a new party wall and excavations.  There are three different types of 'Notice' and your project may require 1, 2 or all 3 of the Notices to be served to each Adjoining Owner.


Once the Notice(s) are served on your Adjoining Owner(s) they have 14 days in which to either consent or dissent to the works. 

Adjoining Owners consent to Notices

If the Adjoining Owner(s) consent then depending on the type of Notice served you are entitled to proceed with the works after either one month (in the case of a Line of Junction Notice or Three Metre / Six Metre Notice) or after two months (in the case of a Party Structure Notice).  In this case it is likely a Party Wall Award will not be necessary, however I would recommend that a Schedule of Condition of the adjoining properties is carried out and that this is agreed between the parties before works commence.

Adjoining Owners dissent to Notices

If the Adjoining Owner(s) dissent to the works then a dispute is deemed to have arisen under Section 10 of the Act and a Party Wall Award must be drawn up.  The Adjoining Owner can either appoint the Building Owner's Surveyor as an 'Agreed Surveyor' and the Award is drawn up by that one Surveyor, or alternatively the Adjoining Owner can appoint his/her own Surveyor, in which case the Award is drawn up and agreed between the Building Owner’s Surveyor and the Adjoining Owner’s Surveyor.  Using an Agreed Surveyor will usually be quicker than if there are two Surveyors involved.  In all cases the Surveyor(s) will be acting impartially.

What is a Party Wall Award?

A Party Wall Award is a legal document that will provide authorisation to the Building Owner to carry out the works in a specific manner, during specific times, along with any other related matters. It will include drawings of the proposed works and also a Schedule of Condition of the Adjoining Owner’s property. The Award is signed by both parties then served on both parties. Construction can then start straight away following service of the Award, although good practice is after 14 days (subject to all other statutory consents e.g. planning permission).

What is a Party Wall?

A Party Wall is a wall that is shared between two buildings. A Party Structure is a floor between flats, and a Party Fence Wall is a masonry garden wall shared between two land owners. All three are covered under the Party Wall etc. Act 1996.
