A party wall award in London is a legally binding document that sets out how notifiable works may proceed. Lenio prepares Awards for Building Owners and Adjoining Owners.
When a neighbour dissents to a Party Wall Notice, or fails to respond within 14 days, surveyors are appointed to resolve the matter. The result of that process is a Party Wall Award.
Under the Party Wall etc. Act 1996, a Party Wall Award is a legally binding document prepared by the appointed surveyor or surveyors. It sets out the conditions under which notifiable works may proceed, covering everything from access arrangements to protective measures for the Adjoining Owner’s property.
In practice, the Award is not a barrier to your project. It is the formal route through which works continue. Once the Award is served, construction may proceed in accordance with its terms.
A Schedule of Condition is more thorough than a basic inspection. The surveyor records the condition of the neighbouring property inside and out, using written descriptions and photographs. There are six key areas every report covers.
The Award defines the notifiable works the Building Owner is permitted to carry out. This description forms the legal boundary for everything that happens on site during construction.
The Award sets out the method and sequence of construction. This governs how works are carried out on site and ensures the Adjoining Owner's property is protected throughout the build.
The Award specifies the hours during which construction may take place and the site practices the contractor must follow. This protects the Adjoining Owner from unnecessary disruption throughout.
The Award confirms the access arrangements under Section 8 of the Act. It sets out when and how the Building Owner and contractor may access the neighbouring property during construction.
The Award specifies the protective measures the Building Owner must put in place during construction. These safeguard the Adjoining Owner's property and may include temporary support or structural protection.
The Award confirms how surveyor fees are allocated. In most cases, the Building Owner covers the reasonable costs of both surveyors as part of the party wall award process.
A Party Wall Award is not required in every case. Where an Adjoining Owner consents within 14 days, works can proceed without one. However, there are four situations where an Award is required or strongly advisable.
When an Adjoining Owner formally dissents to a Party Wall Notice within 14 days, surveyors are appointed and a Party Wall Award must be prepared before any notifiable works begin.
If an Adjoining Owner does not reply within 14 days of receiving the notice, a dispute is treated as having arisen automatically. Surveyors are appointed and an Award must follow.
If an Adjoining Owner serves a counter-notice and the parties cannot agree on the modifications requested, the matter proceeds through the formal route and a Party Wall Award is prepared.
In some cases, both parties agree to appoint a surveyor and prepare a Party Wall Award even where consent was possible. The Award then provides formal protection for both sides.
When surveyors are appointed following dissent, both parties have a choice about how that appointment is structured. The route you take shapes how the party wall award process runs from that point.
When both the Building Owner and Adjoining Owner agree, a single Agreed Surveyor can be appointed to act for both parties. This is often a quicker and more straightforward route through the party wall award process.
The Agreed Surveyor acts impartially and prepares the Party Wall Award without the need for two separate appointments. Both parties must consent to this arrangement. If either party later withdraws consent, separate surveyors must be appointed instead.
Where the parties do not agree on a single surveyor, each appoints their own. The Building Owner appoints a Building Owner’s Surveyor and the Adjoining Owner appoints an Adjoining Owner’s Surveyor independently.
Once two surveyors are appointed, a Third Surveyor is also selected at the same time. The Third Surveyor takes no active role unless the two appointed surveyors cannot agree on a matter. Their selection is a statutory safeguard built into the Act.
Once the Party Wall Award is served, both the Building Owner and the Adjoining Owner have 14 days to appeal it to the county court. Subject to that period passing without challenge, works may proceed in accordance with the Award’s terms.
During construction, the Building Owner must comply fully with the Award. The contractor must respect all access arrangements and put the required protective measures in place as specified. If the contractor departs from the Award conditions, the Adjoining Owner can raise a formal complaint.
After construction, the Schedule of Condition remains the key reference document. If a damage claim arises, Lenio compares the affected areas against the pre-construction record and advises both parties on the appropriate next steps.
Speak directly with a party wall surveyor in London. In one short call, Lenio can confirm whether a Party Wall Award applies to your situation and explain exactly what happens next.
Party Wall matters can feel complicated at first, especially if this is your first building project. The process becomes much easier when each stage is explained clearly and handled in the right order.
We review your project and the Adjoining Owner's response to confirm whether a Party Wall Award is required. This establishes your position under the Act and the correct next steps for your project.
We handle the formal surveyor appointment following dissent or deemed dissent. Where both parties agree, we act as the Agreed Surveyor. Where separate appointments are required, we accept our role promptly and without delay.
Before works begin, we carry out a full Schedule of Condition survey of the neighbouring property. This creates a detailed written and photographic record that forms an annexed part of the Party Wall Award.
We serve the completed Party Wall Award on both the Building Owner and the Adjoining Owner. The 14-day appeal period then begins, after which works may proceed in accordance with the Award's terms.
Where required, we complete a Schedule of Condition and prepare a Party Wall Award. Both documents protect you during the works and set out clearly how and when construction should proceed.
We remain available throughout the construction phase to advise on compliance with the Award. We respond to any concerns raised, inspect reported damage and compare site conditions against the Schedule of Condition where required.
A Party Wall Award is only as effective as the care and detail behind it. An Award that misses key protective measures or contains procedural errors can create significant problems during construction. For this reason, the quality of every Award matters as much as whether one is needed at all.
In London, party wall award matters arise on most renovation projects. Terraced houses, semi-detached homes and converted flats mean that shared walls, tight boundaries and close-proximity excavations are the norm. A thorough and accurate Award, prepared before works begin, is the most reliable protection available to both sides.

Yes. Once the Party Wall Award is served, both the Building Owner and the Adjoining Owner have 14 days to appeal it to the county court. Either party may challenge the Award if they believe it does not properly reflect the requirements of the Act.
In practice, appeals are relatively uncommon on straightforward residential projects. A well-prepared Award that addresses the interests of both parties reduces the likelihood of a challenge within the appeal period.
If the Building Owner fails to comply with the terms of the Party Wall Award, the Adjoining Owner has legal recourse under the Act. This can include seeking an injunction to stop works being carried out in breach of the Award’s conditions.
In addition, the Building Owner remains liable for any damage caused as a result of non-compliance. The Schedule of Condition annexed to the Award is the key evidence in any damage assessment that follows.
A Party Wall Award does not have a fixed expiry date under the Act. However, if works do not begin within a reasonable period or the project changes significantly, the Award may no longer cover the works as described.
If a project is substantially delayed or the scope changes, Lenio can advise on whether a new or amended Award is required before works resume or proceed under the original document.
As a general rule, the Building Owner covers the reasonable costs of the party wall award process, including the preparation of the Award and the fees of both surveyors. This is set out in the Party Wall etc. Act 1996 and applies to most standard residential matters.
The exact costs depend on the complexity of the works and the number of Adjoining Owners involved. Lenio provides a clear written confirmation of the fee position before accepting any appointment. There are no surprises.
If the scope of the proposed works changes significantly after the Party Wall Award is served, the original Award may no longer be sufficient to cover what the Building Owner intends to carry out. In that case, a revised or supplementary Award is required.
Minor changes that fall within the description of works already set out in the Award may not require a new document. Lenio can advise on whether the proposed change falls within the existing Award or requires a further formal step under the Act.
An Agreed Surveyor is a single surveyor appointed by both the Building Owner and the Adjoining Owner to act for both parties in preparing the Party Wall Award. This is an alternative to each party appointing their own surveyor independently.
The Agreed Surveyor acts impartially throughout the process. Both parties must consent to the arrangement. Either party may withdraw consent and appoint their own surveyor at any point before the Award is issued.
If your neighbour has dissented or you are unsure what the next step requires, the right starting point is a conversation. Lenio prepares Party Wall Awards for Building Owners and Adjoining Owners across London. There is no obligation.
