The importance of drain surveys is often overlooked by many homeowners until the unthinkable happens – a clogged drain. There’s nothing worse than dealing with a drainage issue that could’ve been prevented by a simple survey. Many people shy away from these surveys due to the unknown cost, or the misconception that they’re expensive. In this post, we’ll be unveiling the mystery surrounding drain survey costs.



Drain surveys involve the utilization of advanced technology to inspect the condition of drainage systems. They help in identifying any potential or existing problems within the system such as blockages, root intrusions or even structural issues. The need for a drain survey is often prompted by recurring drainage problems, prior to a home purchase, or as a preventative measure for peace of mind.

These surveys are critical for homeowners as they can help to identify potential issues before they escalate into something more serious. Think of them as a diagnostic tool for your drains. Just as you would undergo a medical check-up to prevent serious health conditions, your drainage system also needs regular check-ups to maintain optimal functionality.

The cost of a drain survey is often a topic of concern among homeowners. In reality, the cost is usually a small price to pay compared to the potential costs of large-scale repairs or replacements if a major problem goes unnoticed. However, it’s important to note that the cost of a drain survey can vary based on several factors.


Factors Affecting Drain Survey Costs

When it comes to determining the cost of a drain survey, several factors come into play. These include the type of survey performed, the size, and complexity of your property, the location of your property, accessibility to your drains, and whether any additional services or equipment are needed. The time of year may also affect the cost of your survey with peak seasons generally being more expensive.

The type of survey conducted can greatly influence the total cost. Different surveys offer varying levels of detail, with some requiring more specialized equipment or more time to complete. As expected, more detailed surveys will incur higher costs.

The size, complexity, and location of your property all influence the amount of time and effort required to perform a survey. Larger properties with intricate drainage systems will require more time and hence will be more expensive. Properties located in remote areas may also attract higher costs due to travel expenses.


Types of Drain Surveys

  1. CCTV Drain Survey: This is the most common type of drain survey where a camera is inserted into the drains to provide real-time footage of the state of your drains.
  2. Homebuyer’s Drain Survey: This survey is typically done before purchasing a new home to ascertain the condition of the drains.
  3. Pre-purchase Drain Survey: Similar to a homebuyer’s survey, this is conducted before closing a sale to prevent any unexpected drainage issues.
  4. Drainage Condition Survey: Conducted to ascertain the overall health of the drains, this survey can highlight any potential issues that may need addressing.
  5. Structural Drain Survey: This is a comprehensive survey that checks for any structural issues within the drain system.

The costs associated with each of these surveys will vary based on the factors discussed above.


Average Costs of Drain Surveys

National Average Cost

According to data, the national average cost for a drain survey ranges between £100 and £800. However, it’s worth noting that this is just a ballpark figure, and the true cost can vary based on many factors.

Comparison of Prices Among Companies

Different companies may offer different prices for drain surveys. It’s always a good idea to shop around and get several quotes before making a decision.

Factors That May Increase or Decrease Cost

The price can increase or decrease based on factors such as the size of your property, the type of survey you choose, the complexity of your drainage system, and any extra services you might need.


Benefits of Investing in a Drain Survey

Investing in a drain survey can provide numerous benefits for homeowners. Firstly, it can help prevent costly repairs in the future. By identifying potential issues early, you can address them before they escalate into major problems. This can save you a significant amount of money in the long run.

Secondly, a drain survey can be a powerful tool when negotiating the price of a property. If the survey reveals any potential issues, you can use this information to negotiate a lower price. This can result in significant savings.

Lastly, having a drain survey conducted provides peace of mind. Knowing that your drains are in good condition can relieve a lot of stress and anxiety. This is particularly beneficial for new homeowners who may not be familiar with the state of their drains.


Additional Services and Equipment

  1. Drain Mapping: This involves creating a map of your drainage system which can be useful in identifying problem areas.
  2. Drain Cleaning: This is often done after a survey to clear any blockages or debris in your drains.
  3. Sonar Tracing: This is used to track the path of your drains and can be particularly useful in identifying collapsed drains.
  4. Excavation and Repairs: If a serious issue is identified during the survey, excavation and repairs may be required.
  5. It is vital to bear in mind the costs for these services and include them in your budget when planning a drain survey.

DIY vs Professional Drain Surveys

While it might be tempting to opt for a DIY drain survey to save money, it’s generally not recommended. Drain surveys require specialized equipment and expertise to conduct effectively. Without the necessary skills and experience, you risk missing crucial details about the state of your drains.

On the other hand, professional drain surveys are conducted by experts with years of experience. They have the necessary skills and equipment to conduct a thorough survey of your drains. They can identify potential issues quickly and accurately, providing you with a detailed report of their findings.

When it comes to cost, professional drain surveys might appear more expensive upfront. However, the benefits they offer in terms of accuracy and thoroughness can save you money in the long run, making them a worthwhile investment.


Understanding Drain Survey Reports

A drain survey report provides a detailed overview of the state of your drains. However, without the necessary knowledge, these reports can be challenging to understand. Common terms like ‘inlet’, ‘outlet’, ‘run’, ‘manhole’, and ‘junction’ may be unfamiliar to many homeowners.

Understanding these terms is key to interpreting the results of your survey. Familiarizing yourself with these terms prior to your survey can help you better understand the results and take appropriate action.

In some cases, your survey may reveal potential issues that require immediate attention. In others, it may show that your drains are in good health. Regardless of the results, the information provided by a drain survey is invaluable in maintaining the health of your drains and preventing costly repairs.


Tips for Choosing a Drain Survey Company

When choosing a drain survey company, it’s important to do your research. Start by comparing different companies and getting quotes from each. This will give you an idea of what to expect in terms of cost.

Next, read reviews and ask for recommendations. This can provide insight into the quality of service offered by different companies. Always consider the experience and qualifications of the company. Companies with more experience are likely to provide a more accurate and comprehensive survey.

When you receive a quote, be sure to ask for a detailed breakdown. This can help you avoid any hidden costs and ensure that you’re getting value for your money. Always bear in mind the old adage, “You get what you pay for.” While it might be tempting to go for the cheapest option, it might not always provide the best value.



Drain surveys are an essential tool for maintaining the health of your drains. They can help prevent costly repairs and provide peace of mind for homeowners. While the cost might seem high initially, the benefits they provide far outweigh the costs.

So, don’t wait until you’re faced with a drainage issue. Invest in a drain survey today and rest easy knowing your drains are in good health. After all, prevention is better than cure!
