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!”

The team at Squarepoint were very helpful, knowledgeable and understanding when dealing with my loft conversion and party wall agreement.”

We have used Squarepoint Chartered Surveyors at several of our Parishes and have found them to be very efficient in the production of reports on a variety of issues such as building condition surveys and PPM, defect investigations and Party Wall matters.”

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.
