Frequently Asked Questions
Why do I need a Pre-Build Survey for my Chertsey extension?
A Build-Over Agreement is required if you are building within 3m of a public sewer in Chertsey. It protects you and the water authority.
Will this survey satisfy Thames Water in Chertsey?
Yes. We use WinCan reporting software, which is the industry standard accepted by Thames Water and Chertsey building control.

We will provide a clear HD video of the damage and a fixed-price quote to repair it before your Chertsey build commences.
Do I need a post-build survey as well in Chertsey?
Often, yes. Water authorities in Chertsey may require a “Post-Build” check to ensure your construction hasn’t damaged the sewer.

Usually, these surveys are valid for 12 months, provided no significant groundworks have occurred on your Chertsey site since the check.
