The Act provides a legal framework to prevent and resolve disputes between neighbors when building work affects shared walls, boundary walls, or nearby excavations. If your project involves any of these, you must comply by serving the correct notices.
You need to serve a notice if you plan to:
The notice must be in writing and include:
The adjoining owner has 14 days to respond:
If there is no response within 14 days, the law treats this as a dissent, and a dispute is deemed to exist. You must then:
If damage occurs to the adjoining property as a result of your works:
The adjoining owner should report damage as soon as it is noticed, ideally during or immediately after the works. There is no strict statutory time limit in the Act, but prompt reporting is essential for accurate assessment. Surveyors typically allow a reasonable period after completion (often a few weeks) for claims to be raised.
A Party Wall Award is a legally binding document prepared by surveyors. It includes:
The building owner (the one carrying out the work) usually pays all reasonable costs, including surveyor fees and the Award.
Non-compliance can lead to:
No. Work can only begin after the Award is finalized and served and expiry of the notice period.
The Act protects property owners when neighboring building works could impact shared walls, boundary walls, or nearby foundations. If your neighbor plans such work, they must serve you a Party Wall Notice before starting.
You have 14 days to respond:
If you do not respond within 14 days:
No. In most cases, the building owner pays all reasonable surveyor fees and costs related to the Party Wall Award.
A Party Wall Award is a legally binding document prepared by surveyors. It sets out:
If your property is damaged:
You should report damage as soon as it is noticed, ideally during or immediately after the works. While the Act does not set a strict time limit, prompt reporting ensures accurate assessment and resolution.
No. The Act grants the building owner reasonable access for works, provided proper notice is given and conditions are set in the Award.
You can appeal to the County Court within 14 days of receiving the Award. However, appeals can be costly and should only be considered for serious issues.
You can appoint your own surveyor or agree to use one Agreed Surveyor for both parties. Having your own surveyor ensures independent representation.
A Third Surveyor is an impartial expert appointed when two surveyors (one for each owner) cannot agree on certain aspects of the Party Wall Award. The Third Surveyor acts as an independent adjudicator to resolve disputes fairly.
The Third Surveyor is appointed at the start of the process by the two Party Wall Surveyors. This is a precautionary measure in case disagreements arise during the preparation of the Award.
The Third Surveyor:
Either:
Not usually. The two appointed surveyors prepare the Award. The Third Surveyor only steps in to resolve specific points of disagreement. However, in rare cases, the Third Surveyor may take over and complete the Award if necessary.
The costs are typically borne by the party whose actions caused the referral. For example:
Yes. The Third Surveyor’s ruling is legally binding under the Party Wall etc. Act. However, either party can appeal to the County Court within 14 days of the decision.
In most cases, the Third Surveyor is appointed but never called upon. They only become active if there is a genuine disagreement between the two surveyors that cannot be resolved through discussion.
