Party Wall Surveyors London, Notices. Awards. Disputes. Handled.
- info@leniogroup.com
You are not dealing with a call centre or a faceless agency. You get direct access to an experienced party wall surveyor. He is also a Chartered Civil and Building Engineer with over 20 years of practice. From the first conversation to the final Award.
Most surveyors offer party wall as one service among many. It sits alongside building surveys, planning and other property work. As a result, your project becomes one of many different types they handle each week.
In contrast, an experienced party wall surveyor works differently. The Party Wall etc. Act 1996 is a specific piece of legislation with its own process, notice requirements and dispute rules. For this reason, getting it right requires deep knowledge of that framework, not a general awareness of it.
In short, party wall matters are the only work we take on. That focus is what your project deserves.
ICE: Institution of Civil Engineers
CABE : Chartered Association of Building Engineers
Lenio is led by Sadadcharam Easwaran. He is a Chartered Civil Engineer and Member of the Institution of Civil Engineers (ICE). He is also a Chartered Building Engineer and Member of the Chartered Association of Building Engineers (CABE).
He has over 20 years of experience working as a party wall surveyor across London. In that time, he has managed all types of party wall matters. These range from straightforward notices on rear extensions to complex Party Wall Awards on basement excavations and structural works in dense urban areas.
In practice, when you contact Lenio, you speak directly with him. Not a call handler. Not a junior member of staff. The chartered party wall surveyor who manages your matter from start to finish.
One surveyor. Your project. Start to finish.
In practice, ICE and CABE are not titles you are simply given. They are memberships that require proven competence, ongoing training and following a code of conduct. Here is what they mean for your project.
Institution of Civil Engineers
In short, a Chartered Civil Engineer understands how structures behave. Load spread, ground movement, foundation behaviour, the effect of excavation on neighbouring structures. For party wall matters involving basement digs, deep foundations or structural works on shared walls, this technical knowledge shapes every assessment. As a result, it informs every document Sadadcharam produces.
Chartered Association of Building Engineers
Also, a Chartered Building Engineer understands how buildings are built and how works affect existing fabric. For party wall matters, this means a precise knowledge of how proposed works interact with a neighbouring property. In turn, it informs the Schedule of Condition, the Party Wall Award, and every decision made during the process.
Together, these credentials mean you are working with an experienced party wall surveyor who understands the structural and construction impact, not just the paperwork behind them.
To be the most trusted party wall surveying practice in London. Where every homeowner, on both sides of a shared wall, leaves the process feeling they were advised clearly and treated fairly.
To manage the Party Wall process correctly and completely, so London homeowners can build with confidence and neighbours can get through construction without conflict.
Every homeowner deserves to understand what is happening at every stage. That is why we explain the process in plain language. As a result, you will always know where you stand and what comes next.
The Party Wall etc. Act 1996 requires surveyors to act fairly to both sides, even when appointed by one party. In practice, that is not just a legal duty. It is how we work on every instruction.
Cutting corners on the Party Wall process creates delays, disputes and costs for everyone involved. For this reason, we follow the Act correctly from the first notice. No shortcuts.
Construction is disruptive. In fact, the right Party Wall process does not just protect properties. In turn, it protects the bond between neighbours during works and after them.
London homes sit close together. Terraced houses, converted flats, Edwardian semis and tight urban plots mean that most building projects have the potential to affect a neighbouring property. As a result, these are the party wall matters an experienced party wall surveyor handles day to day.
Extensions are one of the most common sources of Party Wall Notices in London. In practice, building close to a boundary or excavating near neighbouring foundations often triggers the Act. For this reason, we advise Building Owners on what notices are needed before a single brick is laid.
Most loft conversions in terraced or semi-detached homes involve cutting into or building off a party wall. In particular, inserting steel beams into a shared structure is notifiable work under the Party Wall etc. Act 1996. In both cases, we manage the notice process and protect both sides correctly.
Basement projects are the most complex party wall cases. Specifically, deep excavation near neighbouring foundations triggers the 3-metre and 6-metre rules under the Act. As a result, the structural implications require careful assessment and a properly prepared Party Wall Award.
Removing a chimney breast attached to a party wall is notifiable work. Moreover, it affects the structural strength of a shared element. For this reason, we assess the impact, serve the correct notice and make sure the process protects the adjoining property throughout.
Building a new wall at or along the boundary falls under the line of junction provisions of the Act. So does carrying out works to an existing boundary structure. In either case, we confirm what applies and serve the right notice before works begin.
Raising, thickening, cutting into or underpinning a party wall all require formal notice. These are works that directly affect the shared structure between two properties. In each case, we prepare and serve the correct Party Wall Notice and manage the full process through to completion.
Most people assume a party wall surveyor works for whoever is paying them. Under the Party Wall etc. Act 1996, that is not how it works.
In practice, an experienced party wall surveyor operates in a quasi-judicial role. Even when appointed by the Building Owner or the Adjoining Owner, the surveyor’s duty is to the Act itself. That means assessing the works fairly and preparing documents that are legally sound. It also means making decisions that protect both sides, regardless of who instructed them.
Above all, this is not optional. In short, it is a legal duty set out in the Act. A surveyor who does not understand or honour that duty is not doing their job correctly.
As a result, Sadadcharam applies this standard to every instruction. That is why both Building Owners and Adjoining Owners trust Lenio to handle their matter. When you work with an experienced party wall surveyor who understands this duty, both sides of a shared wall are properly protected.
Appointed by one party. Accountable to both.
Knowing who your experienced party wall surveyor is and what they stand for is one thing. Knowing what to expect when the work begins is another. Here is how we manage every instruction from first contact to completion.
At every stage of the Party Wall process, we explain what has happened, what comes next and what it means for your project. As a result, you will not be left waiting for updates or unsure what is happening. Plain language, every time.
Party Wall matters have set timelines. For this reason, we manage those timelines proactively. Notices go out on time. Responses are followed up. Appointments are made without delay. Your project does not stall because of a process gap.
Whether we are acting for the Building Owner or the Adjoining Owner, we make sure the relevant parties understand the process and their position within it. In turn, a well-informed process is a smoother process for everyone involved.
A Party Wall Notice served the wrong way restarts the clock. Also, a poorly drafted Party Wall Award creates disputes. For this reason, we prepare every document to the legal standard the Act requires, so the process does not have to be repeated.
Whether you are planning works or have received a notice from your neighbour, the first call costs nothing. Speak directly with an experienced party wall surveyor and leave knowing exactly where you stand.
