Party Walls: What options does an Adjoining Owner have?

The Party Wall etc. Act 1996 states that, should a Building Owner wish to carry out any modifications to their home that affects a shared wall, they need to follow a specific procedure to protect their interests and those of the affected Adjoining Owner.

In a best-case scenario, the Building Owner has taken the time to discuss their plans with their neighbours well in advance of the work being started. However, it’s not uncommon for Adjoining Owners to only become aware of the project when they receive a Party Wall Notice through the letterbox. In either case, it’s important that Adjoining Owners understand their options and how their response will affect the proceedings.

Option 1 – Adjoining Owner who has received a notice

If you are an Adjoining Owner that has received a Party Wall Notice, the first option you have is to provide full, written consent for the proposed works. This option is seldom recommended (if ever), as it leaves your home vulnerable to related damage that the Building Owner may not be considered responsible for.

Dissenting in order to have a Party Wall Award drawn up and have the current condition of your property documented is prudent, even if you have no further concerns about the work.

It is important to note that if you do not provide a formal response within 14 days, you are deemed to have dissented and therefore be in dispute.

Option 2 – Should you share the same surveyor as your neighbour

If you should choose to dissent, the next step is to decide whether you are comfortable sharing the same surveyor as your neighbour. This is an accepted and common practice, and the appointed surveyor is obliged to act impartially – you should not need to worry about being at a disadvantage by agreeing to a jointly-appointed surveyor.

However, it is important to select a surveyor that has experience in Party Wall matters. This should include Schedules of Condition and Party Wall Awards that address any potential issues with the project, such as security, noise, vibration, dust and temporary access.

Option 3 –  Provide and Instruct Your Own Separate Surveyor

If you are not happy with the Building Owner’s choice of surveyor, you can provide dissent and instruct your own, separate surveyor. In normal circumstances, the Building Owner is responsible for all reasonable surveyor fees.

The two surveyors will then negotiate the terms of the Party Wall Award so that they are fair and reasonable for both parties. In this scenario, the two surveyors will jointly appoint a third surveyor, who will make a final decision in any circumstances where they cannot agree. However, this situation is uncommon.

From the very first time I called Scott, he was very attentive to my requirements for a building survey. From the outset he noted down my areas of concern, updated me with progress prior to the survey and gave me a thorough debrief after the survey. The quality of his report was excellent, very easy to understand and, importantly, comprehensive.

I was extremely pleased with the excellent service provided by Scott Buchanan of Squarepoint Chartered Surveyors, and  I hope to contact yourselves in due course with a view to getting further advice.

Working with Adam Graham at Squarepoint was a very smooth and easy process. He was always clear and thorough in our communication and provided very detailed advice. I would highly recommend Squarepoint!”

Young, trustworthy, professionally competent and committed to delivering on time and on budget.”

Fast and friendly service with an extremely thorough survey. The Surveyor’s phone call to explain the findings of the report, before the official survey was sent, was invaluable.

I used Squarepoint for a party wall agreement. From my initial conversation with Eve through to Adam completing the party wall award, the process was smooth, professional and timely given the challenges of COVID lockdown. Thank you for your great service.

Really helpful team at Squarepoint, on hand to help with any queries and take you through the whole process clearly and at a pace guided by you. Our party wall surveyor, Adam, was great at communicating and efficient throughout  the whole process, could not ask for more.

I had been hunting for a simple job that required a surveyor’s expertise, but had been struggling to find trust throughout my enquiries, until I spoke to Adam.

The advice simply and honestly given by Adam on our first call was remarkable. His friendly but competent application and manner made it easy for me to hire him, and not only did he more than deliver on the required services, but his price was the most competitive I could find. Would highly recommend Eve and Adam at Squarepoint.”


I recently hired Adam to help with a party wall award required on both sides of my terraced house.

He was able to liaise with both parties to answer their initial questions/concerns, which led to them both appointing him as the agreed surveyor, which saved me time and money.

Adam prepared the final award comprehensively and quickly. I would thoroughly recommend him and his friendly Admin assistant Eve.
