Keeping your water tank clean is essential for ensuring safe and healthy water in your home or business. Over time, tanks can accumulate dirt, sediment, and bacteria, causing health risks such as Legionella and E.Coli. Regular cleaning prevents these problems, ensuring your water remains safe to use.

But how much does it cost to get your water tank professionally cleaned in Ireland? The answer can vary based on several factors, such as the size of the tank and the extent of cleaning required.

In this blog, we will look at the costs involved in water tank cleaning in Ireland, so you know exactly what to expect. Read on to find out more!

What Factors Influence the Cost of Water Tank Cleaning?

Understanding what affects the cost of water tank cleaning can help you budget more accurately. Here are the main factors you should consider when planning for this essential maintenance.

Size of the Water Tank

The size of your water tank is one of the primary factors that influence the cost of cleaning. Larger tanks require more time and resources to clean, which can increase the overall cost. Smaller tanks, on the other hand, might be less expensive due to the reduced effort and materials needed.

Moreover, the volume of water stored in the tank can impact the complexity of the cleaning process. Tanks holding more water may require more thorough cleaning to ensure all contaminants are removed, adding to the cost.

Level of Contamination

The extent of contamination in your water tank also plays a significant role in determining the cleaning cost. Tanks with heavy buildup of sediment, algae, or other pollutants need more intensive cleaning, which can be more expensive.

A lightly contaminated tank might require just a basic cleaning service, which tends to be more affordable. Regular maintenance can help keep contamination levels low and reduce cleaning costs over time.

Accessibility of the Tank

How easy it is to access your water tank can affect the cost of cleaning services. Tanks that are difficult to reach or require special equipment to access will likely induce higher cleaning costs. This is because extra effort and time are needed to ensure the tank is properly cleaned.

For tanks located in easily accessible areas, the cleaning process is usually straightforward and less time-consuming, leading to lower costs. Always consider the location and accessibility when planning for water tank cleaning.

Frequency of Cleaning

Regularly scheduled cleanings can influence the overall cost of maintaining your water tank. Frequent cleanings can prevent severe contamination, making each cleaning session quicker and less costly. On the other hand, if cleanings are infrequent, the buildup can be more severe, requiring more intensive and expensive cleaning.

Establishing a routine cleaning schedule with your service provider can help manage costs and ensure your water tank remains in good condition. This proactive approach can save you money in the long run.

Type of Cleaning Service

The type of cleaning service you choose will also affect the cost. Basic cleaning services might involve simple scrubbing and flushing, which are generally less expensive. More comprehensive services that include disinfecting, sediment removal, and thorough inspections will cost more.

Choosing the right level of service depends on the condition of your tank and your specific needs. It's essential to discuss options with your service provider to determine the most appropriate and cost-effective cleaning plan for your water tank.

What is the Average Cost of Water Tank Cleaning in Ireland?

The average cost of water tank cleaning in Ireland varies based on whether the tank is for domestic or commercial use. For domestic water tanks, prices typically range from €300 to €600. This cost covers the inspection, draining, cleaning, and disinfecting of smaller tanks found in homes.

Commercial water tank cleaning is generally more expensive due to the larger size and higher complexity of the tanks. Prices for commercial tanks can range from €700 to €2,000, depending on factors such as tank size, level of contamination, and accessibility. Regular maintenance contracts for commercial tanks might offer some cost savings over time.

Ultimately, the exact cost will depend on your specific requirements and the service provider you choose. It's always a good idea to get multiple quotes and discuss the scope of work with potential providers to ensure you're getting a fair price for the services you need.

Are There Ways to Reduce the Cost of Water Tank Cleaning?

Reducing the cost of water tank cleaning is possible with some strategic measures. Here are a few tips to help you save money while maintaining a clean and safe water tank.

Regular Maintenance

One of the most effective ways to reduce the cost of water tank cleaning is through regular maintenance. By scheduling routine inspections and cleanings, you can prevent severe contamination and buildup, making each cleaning session quicker and less costly. 

Regular maintenance helps keep the tank in good condition, reducing the need for extensive and expensive cleanings.

Use a Reliable Service Provider

Choosing a reliable and experienced service provider can also help reduce costs. Reputable providers offer transparent pricing and efficient services, ensuring you get the best value for your money. 

They can provide maintenance plans that include regular inspections and cleanings at a discounted rate, helping you save on long-term costs.

Implement Preventative Measures

Implementing preventative measures can minimise the frequency and intensity of cleanings needed. For example, installing a filtration system can reduce the amount of sediment and contaminants entering the tank. 

Regularly checking and repairing any leaks or issues can also prevent the tank from becoming overly dirty, reducing the need for frequent, deep cleanings.

Optimise Tank Accessibility

Ensuring your water tank is easily accessible can lower the cost of cleaning services. If your tank is difficult to reach, consider making modifications to improve access. 

This can reduce the time and effort required for cleaning, ultimately lowering the overall cost. Easy access allows service providers to perform their tasks more efficiently, saving you money.

Combine Services

Combining water tank cleaning with other maintenance services can also lead to cost savings. Many service providers offer package deals that include multiple services at a reduced rate. 

For instance, scheduling tank cleaning along with gutter cleaning or plumbing inspections can be more economical than booking these services separately.


Keeping your water tank clean is essential for ensuring safe and healthy water. The cost of cleaning varies based on factors like tank size, contamination level, and accessibility. Regular maintenance and preventative measures can help reduce these costs. 

In Ireland, domestic tank cleaning typically costs between €100 to €300, while commercial cleaning ranges from €500 to €1,500.
