Most new properties come with an NHBC or similar guarantee. However, this guarantee only covers certain parts of the building, such as the gas and electric’s for 2 or 3 years.  Although it will likely cover the main building for 10 years, making a claim can be an expensive and difficult process, and probably comes with an excess of £1,000. A thorough survey will almost certainly cost less than this and will give you peace of mind to know that the home you’re buying is free from major defects and worries.
