Received a Party Wall Notice from your neighbour? As an Adjoining Owner, you have rights and options under the Party Wall etc. Act 1996. Lenio explains your position clearly and manages the process on your behalf.
If your neighbour has sent you a Party Wall Notice, you are the Adjoining Owner under the Party Wall etc. Act 1996. This term simply means the owner of a property that may be affected by a neighbour’s proposed building works.
You do not need to take immediate action. However, your response to the notice or your decision not to respond has formal consequences under the Act. Understanding your position as an Adjoining Owner before you reply is the right first step.
Not every notice is correctly prepared. Before responding, check that the notice meets the basic requirements of the Party Wall etc. Act 1996.
A valid Party Wall Notice should include:
If any of these details are missing or incorrect, the notice may be invalid. We can review the notice you have received and confirm whether it meets the legal requirements before you decide how to respond.
Once you receive a Party Wall Notice, you have 14 days to respond. The Act gives you four possible responses. Each leads to a different next stage in the adjoining owner party wall process.
You agree to the proposed works in writing. The party wall process moves forward without the need for surveyor appointments. Works may proceed, though a Schedule of Condition is still advisable to protect your property.
You agree in principle but request modifications or additional protective works. The Building Owner must consider your counter-notice and respond within 14 days. This does not stop the project but adds a negotiation stage.
You formally object to the proposed works. This does not stop the works from proceeding. Instead, it triggers the statutory dispute resolution process and surveyors are appointed to prepare a Party Wall Award.
If you do not respond within 14 days, a dispute is treated as having arisen under the Act. This is known as deemed dissent. Surveyors must then be appointed even without a formal objection from you.
As a general rule, the Building Owner covers the reasonable costs of the party wall process, including the Adjoining Owner’s surveyor fees. In most cases, you can appoint a party wall surveyor for adjoining owners without paying for it yourself.
The exact amount depends on the complexity of the works and the number of properties involved. Lenio provides a clear written confirmation of the fee position before accepting any appointment. There are no surprises.
Speak directly with a party wall surveyor in London. In one short call, we review your notice, explain your rights as an Adjoining Owner and tell you exactly what to do next.
As your party wall surveyor for adjoining owners, Lenio protects your property and your rights throughout the full adjoining owner party wall process.
We review the Party Wall Notice you have received and confirm whether it is valid and correctly served. If it is defective, we advise on the right course of action before you respond.
We explain what the proposed works mean for your property and set out your response options clearly. You understand your adjoining owner rights before you make any formal response to the notice.
Where you dissent or are deemed to have dissented, we accept formal appointment as your Adjoining Owner's Surveyor. We represent your interests throughout the surveyor appointment process and during Party Wall Award preparation.
Before works begin, we carry out a Schedule of Condition survey of your property. This creates a detailed written and photographic record of its condition, protecting you if damage is alleged later.
We review the draft Party Wall Award to ensure it properly protects your interests. This includes checking the scope of works, access arrangements, protective measures and the conditions governing how works proceed.
During the works, we remain available to advise on compliance with the Party Wall Award. We respond to any concerns about construction and inspect any reported damage against the Schedule of Condition record.
As an Adjoining Owner, your property and your neighbour relationship are both affected. An inadequately prepared Party Wall Award can leave your property without proper protection during construction. For this reason, having your own party wall surveyor for adjoining owners is the most practical approach.
In London, adjoining owner party wall matters arise on most renovation projects. The city’s dense housing stock means that shared walls, tight boundaries and close-proximity excavations are the norm. You have the right to representation and you do not have to manage this alone.

You are not legally required to respond. However, if you do not reply within 14 days, the Act treats this as a dispute having arisen automatically. This is known as deemed dissent and results in surveyors being appointed.
In practice, responding clearly gives you control over your position. Taking no action does not protect your property and results in the same outcome as formal dissent, without giving you any say in what happens next.
A valid Party Wall Notice must include the Building Owner’s name and address, the address of the property where works are planned, a clear description of the proposed works and the intended start date. It must state that it is served under the Party Wall etc. Act 1996.
If any details are missing or incorrect, the notice may be invalid. We can review the notice you have received and advise on whether it meets the legal requirements before you respond.
No. The Party Wall etc. Act 1996 is designed to allow certain works to proceed, not prevent them. As an Adjoining Owner, you cannot use the party wall process to block your neighbour’s project entirely.
However, you can use the process to ensure your property is properly protected. Dissenting triggers the formal route under the Act, which leads to a Party Wall Award setting out the conditions under which works must proceed.
In most cases, no. As a general rule, the Building Owner covers the reasonable fees of the Adjoining Owner’s surveyor as part of the party wall process. This is set out in the Party Wall etc. Act 1996 and applies to most standard residential matters.
The exact position can vary depending on the complexity of the works. Lenio provides a clear written confirmation of the fee position before accepting any appointment.
If your neighbour carries out notifiable works without serving a valid Party Wall Notice, you have legal recourse. You can apply to court for an injunction to stop the works and may also pursue a claim for any damage caused.
In practice, seeking advice promptly is important. We can advise you on the correct steps to take if works have already started without the required notice. Acting early gives you the strongest position under the Act.
The Schedule of Condition is the key document in this situation. It records the condition of your property before construction began and provides the baseline for assessing whether any damage is attributable to the works.
We compare the affected areas against the Schedule of Condition record and advise both parties accordingly. The Building Owner is responsible for making good any damage attributable to the notifiable works.
Yes. As an Adjoining Owner, you have the right to appoint your own surveyor independently. You do not have to accept the surveyor the Building Owner suggests.
The only exception is an Agreed Surveyor arrangement, where both parties consent to a single impartial appointment. This requires your agreement. If you prefer independent representation, you are entitled to appoint your own surveyor.
Whether you have just received a notice or are unsure about works already underway next door, the right first step is a conversation. Lenio provides free initial advice to Adjoining Owners across London. There is no obligation.
