What is a Pre-Purchase Plumbing Survey?

A pre-purchase plumbing survey is a thorough inspection of the entire plumbing system in a property which you want to purchase. We detect leaks, clogs, hidden problems, and lack of plumbing maintenance and pinpoint potential plumbing issues. It makes financial sense to invest in pre-purchase surveys before buying a property. The plumbing survey provides a professional opinion on the condition of the entire heating and plumbing system, ensuring no potential hidden plumbing problems are overlooked.

The Plumbing Survey Process


Preparation and Planning for the Survey

Before starting the survey, we explain to the current property owners the steps of the survey and asking to show us around the property. Our plumber plans and prepares the right tools and starts operating the plumbing and heating system to be ready for the checks.

Conducting the pre-purchase survey

Our visual survey will take approximately 60-90 minutes to complete. The testing is another 60 minutes. During this time, our plumber will meticulously inspect the various plumbing infrastructure in each room, including pipes, fixtures, drains, heating system operations, radiators, underfloor heating, controls, hot water cylinders, cold water tanks, leaking areas, and water supply systems.

Our plumber also needs 30 minutes to complete the report and our office team needs another 60 minutes to check and put together the report and send out the email.

Checking Results and Compiling the Report

After checking the whole system, our plumber in London identifies any issues and recommends necessary repairs. We compile a detailed report supported with photos, providing clear and actionable insights.

Factors Affecting the Length of a Plumbing Survey

Size and Complexity of the Property

The property size can significantly affect the length of the survey. Larger properties with more plumbing fixtures and appliances may require an extra 60 minutes to be completed.

Age and Condition of the Plumbing System

Some plumbing systems may need more time to carry out the checks as our plumber will test every plumbing area and write a more detailed report.

Number of Fixtures and Appliances to Inspect

The number of bathrooms, kitchens, boilers and other appliances connected to the plumbing system also impacts the survey duration. More fixtures mean more points to inspect and carry out a comprehensive assessment during our plumbing surveys.
