A pre-purchase drain survey checks the drains before you buy a property. A standard homebuyer survey does not usually include a camera inspection of the drains. Yet drain faults can cost a lot to fix and often hide below ground. A CCTV survey records the pipes so you can see cracks, roots, and displaced joints.
Send the property address and agree a date. Ask the engineer how they plan to reach the drains. Since most access comes through manholes and chambers, you may not need to prepare anything.
A CCTV camera runs through each reachable drain run. It records the pipe condition, the joints, and any defects. While it films, the engineer can note where each defect sits.
Ask for a written report with images and a plan of the pipe routes. For example, you can ask how the engineer grades each section. A clear report is easier to share, because your solicitor can read it quickly.
Pass the report to your solicitor and surveyor. Ask the engineer to explain the findings, and request a repair quote if they find defects. Since you may want to compare prices, a second quote can help.
The cost of a pre-purchase survey depends on the size of the property and how many drain runs it has. A larger site with outbuildings takes more time. Because prices vary, ask for a written quote before the survey starts. Also ask what the price includes, such as the report and the footage.
Book it after the seller accepts your offer, but before you exchange contracts. That way, you have time to act on the findings. Since timing matters, ask your solicitor if you are unsure when to book.
Share it with your solicitor and surveyor, because they can tell you how it affects the purchase. Ask the engineer whether the report includes images, a pipe plan, and a grade for each section. A clear report makes it easier to explain.
You have options. You can ask for a lower price, ask the seller to repair the drain, or walk away. Since repair costs vary, ask for a quote for any defect the survey finds.
