Square Loft Tanks
At Tanks Direct, we offer a wide range of square cold water loft tanks for both domestic and commercial applications. These tanks are ideal for new installations or for replacing outdated galvanised tanks, providing a modern and efficient upgrade. Constructed from high-quality, potable-grade MDPE plastic, our square loft tanks ensure the safe storage of water and come in a variety of sizes, from compact 15-gallon (68 litre) tanks up to 50-gallon (227 litres) framed tanks. To find the perfect size, consider the number of people that will be using the tank and their water consumption habits.
Square loft tanks offer a unique advantage in terms of space utilisation. While they may take up slightly more floor space than round loft tanks, their straight sides often allow for a more efficient fit in specific loft configurations, particularly when positioned in corners or against walls. Our models include insulation, which plays a vital role in maintaining consistent water temperature and helps prevent freezing during the colder months.
At Tanks Direct, we are committed to providing you with exceptional value and offer a competitive price match guarantee, ensuring you receive the best possible deal on your chosen tank. Our friendly and knowledgeable team are on hand to help you choose and, with our Feefo service rating, you can be confident you're getting a reliable product backed by a team that prioritises customer satisfaction.

Square Loft Tanks FAQs
How long do cold water storage tanks last?
Typically, well-maintained cold water storage tanks crafted from durable materials like polyethylene or glass-reinforced plastic (GRP) can last anywhere from 20 to 30 years. The high-quality construction of the tanks sold at Tanks Direct contributes significantly to their longevity, with resistance to corrosion and wear-and-tear ensuring reliable performance over an extended period.
Your proactive involvement in regular maintenance plays a crucial role in determining the lifespan of the tank. Timely inspections for signs of damage, leaks, or structural issues can significantly prolong the tank's functionality. Regularly checking fittings, valves, and the integrity of the tank structure is essential to catch and address potential issues before they escalate.
Exposure to extreme temperatures, UV radiation, or harsh chemicals can accelerate wear. Proper installation and placement in a sheltered, well-ventilated area contribute to the tank's overall resilience.
How do I know the size of the cold-water storage tank that I need?
Determining the appropriate size for your loft cold water storage tank is a critical step in ensuring an efficient and reliable water supply for your household. Start by assessing your daily water usage patterns. Consider the number of occupants in your home and their typical water-related activities, such as bathing, cooking, and laundry. This initial evaluation will provide a baseline for understanding your overall water demand.
Next, consider any specific requirements, such as the use of water for garden irrigation or other outdoor purposes. This comprehensive understanding of your water needs will guide you in selecting a tank size that accommodates both your current usage and potential future requirements.
Finally, it's crucial to be aware of the available loft space for tank installation. Measure the dimensions of your loft to ensure that the chosen tank fits comfortably within the designated area. Additionally, consider the tank's height, as it will affect the gravity-fed water pressure. Adequate water pressure ensures a consistent flow to your taps and appliances.
Do I need to insulate my cold-water storage tanks?
Insulating your cold-water storage tank is a wise decision with several benefits. The primary reason to insulate is to prevent heat loss from the water inside the tank. During colder seasons, uninsulated tanks can experience a drop in temperature, potentially leading to issues like freezing. Insulating your cold-water storage tank helps to maintain a more stable water temperature, reducing the risk of freezing and ensuring a reliable water supply.
By minimising heat loss, you can reduce the energy required to heat the water, which is particularly important if you have a water heating system connected to the tank. This energy-saving aspect not only promotes sustainability but also reflects positively on your utility bills, providing a cost-effective solution in the long run. Regulations often recommend or mandate specific insulation measures to enhance energy efficiency and prevent common issues associated with cold water storage. Ensuring your tank meets these regulations not only keeps you in compliance but also guarantees that your water system operates efficiently and safely.
