Whether you are planning building works or have received a notice from your neighbour, Lenio provides party wall services across London to guide you through the statutory process. In either case, every instruction is managed by an experienced party wall surveyor from first contact to final Award.
The Party Wall etc. Act 1996 sets out a statutory process for building works that affect shared walls and neighbouring foundations. It also covers works at boundary lines and excavation near neighbouring structures. As a result, the party wall services in London you need will depend on your project type and your role in it.
Lenio provides party wall services in London for both Building Owners and Adjoining Owners. In practice, this covers everything from preparing the correct notices at the outset to drafting legally binding Awards when a dispute arises. In each case, the work is managed completely and end-to-end.
Each service is available for homeowners across London. Whether you are a Building Owner planning works or an Adjoining Owner who has received a notice, select the service that matches your situation.
Serving a valid Party Wall Notice in London is the first step in the statutory process. We identify which notices apply, draft them correctly, and serve them in line with the notice periods required under the Act.
A Schedule of Condition records the existing condition of a neighbouring property before building works begin. We prepare a detailed written and photographic survey, protecting both sides if any claim about construction damage arises later.
When a neighbour dissents or does not respond to a Party Wall Notice, a Party Wall Award sets out how works may proceed. We prepare legally binding Awards that protect both sides and keep your project moving.
If you are planning works that fall under the Party Wall Act 1996, we act as your Building Owner's Surveyor. We manage every step on your behalf, from the initial statutory review to the completed Award.
If you have received a Party Wall Notice from your neighbour, we act as your Adjoining Owner's Surveyor. We explain your options, protect your property, and defend your rights under the Act throughout the process.
In some cases, both the Building Owner and Adjoining Owner agree to appoint a single Agreed Surveyor. This can reduce cost and speed up the process, provided both parties are comfortable the surveyor is independent.
The right starting point is a short conversation. Speak directly with a party wall surveyor in London and leave knowing exactly what your project needs.
The Party Wall Act applies differently depending on your role. In both cases, the right party wall services in London start with understanding your position under the Act.
All party wall services in London follow the same clear sequence. Here is what happens from first contact to completed Award.
Send us your drawings, notice or a short explanation of the proposed works. If you do not have everything ready yet, we can still help you understand what may be needed.
We check whether the Party Wall etc. Act 1996 applies to your project and confirm which notices are required. You will know exactly what needs to happen next before anything moves forward.
Where notices are needed, we prepare and serve them correctly on all affected Adjoining Owners. Each notice is drafted to meet the legal requirements and served within the correct notice period before works begin.
If neighbours consent, the process moves forward smoothly. If they dissent or do not reply, surveyors are appointed and the matter is handled through the correct process under the Act.
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.
The Party Wall etc. Act 1996 operates separately from planning permission and building regulations. As a result, securing planning approval does not discharge your party wall obligations. Many London homeowners discover this only after construction has started.
In London, most renovation projects involve shared walls, tight boundary lines, or excavation near neighbouring foundations. For this reason, mistakes in the party wall process are costly to fix and can delay a project by months. The right party wall help in London comes from a surveyor who handles these matters exclusively. That means someone who understands how London’s building stock shapes the risks involved.

That depends on your role and your project stage. If you are planning works, you need notices served and, if your neighbour dissents, a Party Wall Award. If you have received a notice, you need an Adjoining Owner’s Surveyor to protect your property.
If both parties agree, an Agreed Surveyor can manage the process for both sides. In most cases, a short call is enough to confirm which party wall services in London apply to your situation.
A Party Wall Notice is the formal document served on your neighbour before notifiable works begin. It starts the statutory process. A Party Wall Award is a legally binding document prepared later, usually when a neighbour dissents or does not respond.
In short, the notice opens the party wall process and the Award governs how works are carried out. Both are distinct documents with different legal purposes.
The Building Owner’s Surveyor manages the full process on behalf of the person planning the works. That includes identifying which notices are needed, drafting and serving them correctly, and managing the response period with all affected neighbours.
If a neighbour dissents, the surveyor arranges the Schedule of Condition and prepares the Party Wall Award. The goal is to keep the project compliant and moving without unnecessary delay.
An Adjoining Owner’s Surveyor acts on behalf of the neighbouring property owner. They review the proposed works, check that the notices are valid, and arrange a Schedule of Condition before works start.
They then ensure that any Party Wall Award properly protects your interests throughout the construction period. Their role is to defend your rights under the Act.
An Agreed Surveyor is a single appointment covering both parties. This option is available when both the Building Owner and the Adjoining Owner are comfortable with one surveyor managing the process for both sides.
It can reduce costs and simplify communication. However, both parties must consent, and the Agreed Surveyor still has a legal duty to act impartially throughout.
It is not a legal requirement in every case, but it is strongly recommended. A Schedule of Condition records the state of a neighbouring property in writing and photographs before works begin, protecting both sides if damage is alleged later.
For basement excavations, extensions, and loft conversions it is almost always advisable. Without it, disputes about pre-existing versus construction damage are much harder to resolve.
A Party Wall Award covers the scope of the authorised works, construction methodology, and permitted working hours. It also sets out access arrangements, protective measures for the adjoining property, and how surveyor fees are allocated.
It incorporates the Schedule of Condition and is legally binding on both parties once issued. Works must be carried out in accordance with its conditions.
Once the Award is issued, works can proceed in accordance with its conditions. Lenio remains available throughout the build to clarify Award provisions for contractors and owners, and to advise on access and compliance.
If damage is reported, we compare the affected area against the Schedule of Condition to assess whether it is attributable to the works.
Not in the same role. Under the Party Wall etc. Act 1996, each party needs their own surveyor if the matter is disputed. The Building Owner and Adjoining Owner have separate interests that must be represented independently.
However, if both parties agree, Lenio can act as the Agreed Surveyor. This is a single impartial appointment, and is only possible where both parties consent and there is no conflict between their positions.
The party wall services in London that apply to your project depend on your role and how far the process has progressed. In either case, the first step is a conversation with a party wall surveyor in London. The call is free and there is no obligation.
