Build Over Surveys Bank Quay | Expert Reports Warrington

Are you planning to build an extension, a garage, a conservatory, or any new structure on your property? If your project is close to or directly over a public sewer pipe, you will need a formal Build Over Agreement from your local water authority, such as United Utilities. A critical part of this process is getting a professional Build Over CCTV Drain Survey. At Avery Drainage Solutions, we provide the detailed, compliant surveys you need to get your project approved and underway without any hitches. We offer this specialist service across Warrington, Cheshire, Greater Manchester, and Merseyside.

When dealing with water authorities and building regulations, you need a team with the right experience and credentials. Our technicians are not just camera operators; they are drainage experts. With years of experience working on properties across the North West, we understand precisely what surveyors and water authorities need to see in a report. Our CHAS accreditation and CSCS-certified team mean we work to the highest safety and professional standards, whether we're on a domestic property in Lymm or a larger development in Manchester. We provide a competitive, transparent quote and work efficiently to help keep your project on schedule.

Think of it as a detailed inspection for the public sewer running near or under your property. We use a specialist drain camera to record the condition of the pipe. This provides you and the water authority with a clear video record and a technical report. This is needed before you build to prove the pipe is in good shape, and after you build to prove your work hasn't caused any damage.

The public sewer is the responsibility of the water authority. They need to be able to access it for future maintenance and repairs. By building over it, you are taking on some of that responsibility. The survey and the resulting Build Over Agreement are there to protect their asset and to protect you from being blamed for any pre-existing issues with the pipe. It is a non-negotiable part of the planning and building regulations process.

You will receive a comprehensive package ready to submit with your application. This includes the high-definition video footage from the camera, a map of the drain layout showing its path and depth, and a detailed written report (in Wincan format) that notes the pipe material, condition, connections, and identifies any defects or points of interest.

Don't worry. If our survey uncovers an existing issue with the sewer, like a crack or root damage, we will clearly detail it in the report. This is actually a good thing for you, as it proves the problem was there before you started work. We will provide you with straightforward, practical advice and a quote for any repair services that might be needed to get the pipe up to standard before your project can be approved.

For a typical residential property in areas like Sale or Northwich, the on-site survey itself usually takes between one and two hours. We work efficiently to minimise disruption. The time it takes to produce the full report and video files is usually within 24-48 hours, so you can move forward with your plans quickly.
