We help London homeowners navigate the Party Wall Act 1996, from serving the right Party Wall Notice to resolving a Party Wall Dispute with a legally binding Award.
Most people arrive with a practical question. “Do I need to tell my neighbour?”, “Can my neighbour object?”, or “What should I do with this notice?”
Choose the route that sounds closest to your situation.
Planning an extension, loft conversion or basement works? If the work affects a shared wall, boundary or nearby foundation, you may need to serve a Party Wall Notice before building begins.
Our Party Wall Surveyors in London can review your plans and confirm whether the Act applies.
If your neighbour has sent you a Party Wall Notice, you have rights and options. You can consent, dissent or ask for more information before you respond.
Lenio can help you understand the notice and what your options are.
That is completely normal. Party Wall matters are not always obvious early on. Send us your drawings, notice or a short description and we will tell you exactly where you stand.
Just share what you have. We will take a look and explain your next step.
We are a London-based Party Wall surveying practice working with homeowners, neighbours and property professionals across the city.
We handle the full Party Wall process so you do not have to manage it alone. We review what your project needs, make sure the right people are notified, and manage each stage from the first notice through to completion.
You do not need to understand the Party Wall Act 1996 before you call. That is what we are here for. We explain what applies, what does not, and what needs to happen next in clear, practical language.
The Party Wall process uses specific legal terms, but the idea is simple. One person is planning the works. Another person may be affected by those works.
If you are planning the works, you are usually the Building Owner.
As the Building Owner, you may need to notify affected neighbours before carrying out certain works. This applies to work on a party wall, shared structure, boundary line or excavation near neighbouring foundations.
Common examples include rear extensions, side extensions, loft conversions, basement works, chimney breast removal and new walls at or near a boundary.
Our Party Wall Surveyors in London help Building Owners understand what notices are needed, how the process works and what happens at each stage.
If your neighbour is planning the works, you are usually the Adjoining Owner.
As the Adjoining Owner, you may receive a formal Party Wall Notice before works start next door. You do not need to panic. You should understand what the notice means before you respond.
You may want advice on whether the notice is valid, whether a Schedule of Condition is needed, and what your options are before responding.
Our Party Wall Surveyors in London help Adjoining Owners understand their rights and make sure their property is properly protected throughout.
A lot of homeowners are surprised to find that planning permission and Party Wall requirements are completely separate. Getting planning approval does not mean your Party Wall obligations are covered. Depending on the nature of the works, you may still need to follow the Party Wall Act 1996 process before building can begin.
If you are unsure, the safest first step is to have the proposed works reviewed before construction starts.
London homes are often close together. Terraced houses, semi-detached homes, converted flats, shared boundaries and tight building plots can all make Party Wall matters more common.
Many typical London projects involve work that affects a shared wall, boundary or nearby structure. A loft conversion often means inserting steel beams into a party wall. A rear extension can mean building close to a boundary or excavating near neighbouring foundations. Basement projects tend to raise the most technical Party Wall questions, simply because of how deep the excavation goes and the ground movement risk that brings.
The Party Wall Act 1996 is not designed to stop sensible building work. It is there to make sure affected neighbours are properly notified, property condition is recorded where needed, and any Party Wall Dispute is handled through the correct route.
Whether you are in a Victorian terrace in South London, a conversion flat in East London or a new-build near a shared boundary, the same Party Wall rules apply.
Lenio handles the complete Party Wall process for London homeowners, Building Owners and Adjoining Owners. Whether you need one notice or support through a full Party Wall Award, we manage each stage so you do not have to.
We prepare and serve the correct Party Wall Notices so your neighbours are formally informed before notifiable works begin. Correctly drafted notices prevent delays, invalid process and disputes before your project even gets started.
A Schedule of Condition records the condition of a neighbouring property before works start, with written notes and photographs. It protects both the Building Owner and Adjoining Owner if any damage is alleged during or after construction.
If a neighbour dissents or does not respond, a Party Wall Dispute arises and surveyors prepare a Party Wall Award in London. This legally binding document sets out how and when works proceed, so your project can continue through the correct route.
We act for Building Owners planning works near a shared wall or boundary. We help you serve the right notices, follow the correct process and keep your project moving without unnecessary delays or complications.
We advise Adjoining Owners who have received a Party Wall Notice or are concerned about works next door. We help you understand your rights, check the notice and make sure your property is properly protected.
Where both owners agree, a single impartial surveyor handles the full Party Wall process for both sides. This can simplify the process, reduce costs and still protect both parties properly under the Act.
As your party wall surveyor in London, Lenio manages every stage of the party wall award process. From the initial review through to post-construction support, we keep both parties informed throughout.
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 review the nature of your works and confirm whether the Party Wall Act 1996 is likely to apply. We will tell you exactly what notices may be required and what needs to happen next.
Where notices are needed, we prepare and serve them correctly on all affected Adjoining Owners. Each notice is drafted to meet the legal requirements, with the correct time period before works begin.
If neighbours consent, the process can move forward smoothly. If they dissent or do not reply, surveyors are appointed and the matter is handled through the correct process under the Party Wall Act 1996.
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 most common Party Wall problems happen when the process is left too late. A homeowner may assume planning permission is enough, a neighbour may feel surprised by the works, or construction may start before the correct notice has been served.
Early advice helps you avoid unnecessary confusion. It gives you time to confirm whether notices are needed, identify the affected owners and deal with any surveyor appointments before work is due to start.
It can also help protect neighbour relationships. Construction is disruptive enough without uncertainty about legal rights, property condition or responsibility for damage. A clear process reduces the chance of a Party Wall Dispute and helps everyone understand what is happening and why.

The first conversation should help you understand your position, not pressure you into a service you may not need.
Whether you are planning works, have received a notice, or are not sure what applies, we can help. You do not need to have everything figured out before you get in touch.
Share your drawings, notice or a short description of the proposed works. Even a brief overview is enough to get started. You do not need to wait until your plans are finalised.
We explain what the Party Wall Act 1996 means for your specific project, whether notices are needed and what should happen next. No obligation, no pressure to commit.
No. It depends on the type of work and how it may affect shared walls, boundaries or neighbouring structures. Some projects do not fall under the Act. Others may require one or more notices. The best first step is to have your proposed works reviewed by Party Wall Surveyors in London.
No. Party Wall requirements are separate from planning permission and building control. Even if your planning application has been approved, you may still need to follow the Party Wall process before starting certain works.
If an Adjoining Owner does not respond within 14 days, a Party Wall Dispute is treated as having arisen under the Party Wall Act 1996. This does not stop your project. It means surveyors need to be appointed so the matter can proceed correctly.
The Party Wall Act 1996 is designed to allow certain works to proceed while protecting adjoining owners. A neighbour’s dissent does not automatically halt the project, but it does trigger the formal dispute resolution process.
A Schedule of Condition is a written and photographic record of the adjoining property before works begin. It helps show the property’s condition before construction starts and can help avoid confusion if damage is later alleged.
For most projects, the Building Owner covers the reasonable costs of the Party Wall process, including the Adjoining Owner’s surveyor fees where applicable. The exact amount depends on the complexity of the works. We provide clear fee proposals before anything begins.
The statutory notice periods alone are one to two months depending on the type of notice. If surveyors need to be appointed and a Party Wall Award prepared, allow additional time on top of that. Starting the process early, ideally before your contractor is booked, gives you the best chance of staying on schedule.
A Party Wall Dispute arises under the Party Wall Act 1996 when an Adjoining Owner dissents to a notice, does not respond within the required period, or disagrees with how works are being carried out. It is resolved through surveyor appointments and a Party Wall Award, not through court.
Yes. Lenio can advise on next steps even after work has begun. Getting Party Wall guidance beforehand is always preferable. Missed notices or delayed action can complicate the process significantly.
Whether you are at the planning stage, have drawings ready, or just received a notice from a neighbour, we are happy to talk it through. As Party Wall Surveyors in London, we will tell you exactly where you stand.
