If you are buying property in the UK, commissioning a building survey is one of the most important
decisions you can make. A building survey provides a comprehensive assessment of the condition
of a property, helping buyers avoid unexpected repair costs and make informed decisions.


What Is a Building Survey?


A building survey is the most detailed property inspection available in the UK. Carried out by a
qualified chartered surveyor, a building survey examines the structure, fabric, and condition of a
building, including roofs, walls, floors, damp issues, and alterations. A building survey is suitable
for houses, flats, listed buildings, and commercial property.


Why a Building Survey Is Critical When Buying Property


Identify hidden defects: A building survey highlights structural movement, damp, timber decay,
subsidence, roof defects, and poor workmanship that may not be visible during viewings.
Protect your investment: A building survey protects buyers by identifying costly repairs before
exchange of contracts. Findings from a building survey can be used to renegotiate the purchase
price.


Understand future costs: A building survey explains why defects have occurred and provides
guidance on repairs, ongoing maintenance, and long-term ownership costs.
Peace of mind: A mortgage valuation is not a building survey. Only a building survey is carried
out entirely in the buyer’s interest.


When Should You Commission a Building Survey?

A building survey should be instructed after your offer is accepted but before exchange of
contracts. This ensures the results of the building survey can be reviewed and acted upon without
legal commitment.


Who Needs a Building Survey?

A building survey is strongly recommended if the property is over 50 years old, has been extended
or altered, is listed, located within a conservation area, or if you are planning refurbishment works.
