I am Sadadcharam Easwaran, and I have spent more than 5 years as a party wall surveyor in London. In that time I have acted on well over 20+ projects, for Building Owners and Adjoining Owners alike.
People often ask me how to choose a party wall surveyor, because the title is not protected and anyone can use it. This post is my honest advice on what to look for, written from the other side of the desk.
How to Choose a Party Wall Surveyor: What Matters Most
In my experience, choosing well comes down to a few simple things. Knowing how to choose a party wall surveyor is less about credentials on paper and more about how they work.
The best surveyors are clear, fair and quick to respond. They explain the process in plain English, and they protect both homes rather than picking a fight.
Here is what I tell friends and family to look for.
| What to look for | Why it matters |
|---|---|
| Party wall focus | The Act has its own rules and traps |
| Clear communication | You will understand each step |
| Fair, neutral approach | Disputes settle faster |
| Local London knowledge | Terraces and flats raise specific issues |
Look for Real Party Wall Experience
Party wall work is a specialism, not a sideline. I would always choose someone who does it regularly, not once a year.
A surveyor who knows the Party Wall etc. Act 1996 well spots issues early. They get the notices right, and they avoid the mistakes that cause delay.
Ask how many party wall matters they handle. Experience with the Act is worth more than a general surveying background.
I would also ask for examples of recent work. A specialist will happily talk through cases that are similar to yours.
Beware the Surveyor Who Picks Sides
Over the years, I have seen surveyors who treat the process as a battle. That helps no one, and it runs up fees on both sides.
A good party wall surveyor is firm but fair. My duty under the Act is to act reasonably, even when I am appointed by one owner.
If a surveyor sounds like a hired gun on the first call, keep looking. The Act rewards cooperation, not conflict.
Understand the Agreed Surveyor Option
One thing I always explain is the Agreed Surveyor route. Both owners can appoint a single, impartial surveyor.
An Agreed Surveyor is usually faster and cheaper than two surveyors. The role is neutral, so I act for the process, not for one side.
If both neighbours are reasonable, I often recommend an Agreed Surveyor. It keeps costs down and relationships intact.
Building Owner Surveyor or Agreed Surveyor?
If a single surveyor is not right, each side appoints their own. As a Building Owner Surveyor, I represent the person carrying out the works.
The Building Owner Surveyor and the Adjoining Owner Surveyor then agree the Award between them. Both still have a duty to act fairly under the Act.
When you choose, decide first whether you want an Agreed Surveyor or your own Building Owner Surveyor. That choice shapes everything else.
Ask How They Handle the Schedule of Condition
A good Schedule of Condition is where I earn my fee. It records the neighbour’s property in detail before work starts.
Ask any surveyor how thorough their Schedule of Condition is. A rushed, photo-light record protects no one.
I take a careful Schedule of Condition every time, because it prevents most damage disputes before they begin.
Check How They Draft the Party Wall Award
The Party Wall Award is the document that lets the work proceed. A clear Award is precise about method, hours and access.
I draft each Party Wall Award to be fair and practical, so it protects both homes without holding up the build. Vague Awards cause arguments later.
Ask to see how a surveyor approaches the Party Wall Award. It tells you a great deal about how they work.
What Local London Knowledge Adds
London is not one market. It is hundreds of streets, each with its own quirks. A Victorian terrace in Islington raises different issues to a mansion flat in Kensington.
A surveyor who knows the local stock anticipates the problems. Shared chimney stacks, shallow foundations and converted flats all need a practised eye.
I have worked across the city for two decades. That local memory saves time, because I have usually seen the situation before.
Trust Your First Conversation
My best advice is to trust that first phone call. A good surveyor listens, asks the right questions, and explains the next step without pressure.
If you feel rushed, confused, or sold to, keep looking. The right surveyor leaves you calmer than when you called.
I have built my practice on that first impression, because earning trust is most of the job.
A surveyor you trust will save you money in the long run. Clear advice early prevents the expensive arguments later.
Questions to Ask Before You Appoint
Knowing how to choose a party wall surveyor is easier once you have asked a few direct questions. Before you appoint anyone, I would ask:
- How many party wall matters do you handle each year?
- Will you act as an Agreed Surveyor if both sides agree?
- How detailed is your Schedule of Condition?
- What are your fees, and who pays them?
- How quickly do you usually agree an Award?
The answers tell you whether a surveyor is a specialist or a generalist. Trust the one who answers clearly and without jargon.
A Final Word
Choosing a surveyor should not be stressful. In my view, it comes down to specialism, fairness and clear communication, more than anything on a certificate.
In 5+ years across London, the jobs that went smoothest were the ones where both sides trusted a calm, experienced surveyor. The official government booklet is a good starting point if you want to read more.
That, in short, is how to choose a party wall surveyor you can rely on.

Frequently Asked Questions
How to choose a party wall surveyor in London?
Look for a genuine party wall specialist who communicates clearly and acts fairly. Ask how many matters they handle, whether they will act as an Agreed Surveyor, and how thorough their Schedule of Condition is.
Do I need a party wall surveyor, or can I use any surveyor?
You need someone who knows the Act well. Any chartered surveyor can take the role, but the Act has its own rules, so a party wall specialist is far safer.
Can one surveyor act for both neighbours?
Yes. If both owners agree, a single Agreed Surveyor can act impartially for both. It is usually the quickest and most cost-effective route.
How much does a party wall surveyor cost in London?
Fees vary with the work and whether one or two surveyors are involved. The Building Owner normally pays, and an Agreed Surveyor keeps the total lower.
What qualifications should a party wall surveyor have?
Look for a chartered background and real party wall experience. At Leino Party Wall Surveyors we are ICE and CABE chartered, with more than 5 years of party wall work.
Who pays for the party wall surveyor?
The Building Owner carrying out the works normally pays the reasonable fees. That often includes the Adjoining Owner’s surveyor, because the work is for the Building Owner’s benefit.
How long does it take to appoint a party wall surveyor?
Appointment itself is quick, often a day or two. The longer part is agreeing the Award, which usually takes a few weeks once a surveyor is in place.
