Loft Water Tanks

Loft Water Tanks — Compact, Reliable, and Hygienic Storage for Domestic and Commercial Use

Loft water tanks give you a practical, space-saving solution for water storage in residential and commercial buildings. Most gravity-fed plumbing systems rely on a tank in the roof space to supply cold water to taps, bathrooms, and heating systems. We make our tanks from high-quality polyethylene, giving you a lightweight, corrosion-resistant unit that fits through standard loft hatches and into confined attic spaces. Furthermore, many models carry WRAS approval, making them safe for storing potable water. For larger storage needs, see our 1200 to 6000 Litre Polyethylene Water Storage Tanks and 6000 to 25000 Litre Polyethylene Water Storage Tanks. For guidance on water storage regulations and hygiene standards, refer to WRAS, the Water Regulations Advisory Scheme.

In addition, our range includes rectangular and coffin-style tanks in a variety of sizes, giving you flexibility for different building layouts. In short, loft water tanks are a trusted choice for homeowners, landlords, and contractors who need reliable, long-lasting storage in a compact footprint.

Key Features and Benefits of Loft Water Tanks

These tanks offer several important advantages for domestic and commercial installations. For example:

• Compact, loft-friendly design — Shaped to pass through narrow loft hatches and fit into low-ceilinged spaces. Coffin-style models suit particularly tight attic areas. Consequently, you can install a full-capacity tank even in restricted roof spaces.
• Durable polyethylene construction — UV-stabilised and corrosion-resistant, so the tank gives a long service life without rusting or degrading. Furthermore, the robust build handles everyday use while staying light enough for easy handling.
• Hygienic, food-grade materials — Smooth internal surfaces reduce bacterial growth and make cleaning straightforward. Moreover, WRAS-approved models meet current potable water storage standards.
• Insulation options — Many tanks come with insulation jackets or built-in insulation to prevent heat loss, reduce condensation, and protect against freezing in colder months. As a result, stored water stays at a safe, consistent temperature year-round.
• Easy installation — Standard fittings connect directly to existing plumbing. Therefore, installation is quick and straightforward for both professional plumbers and experienced DIY users.
• Range of sizes and shapes — Rectangular and coffin-style options suit different roof space configurations. In addition, a variety of capacities means you can match the tank to your property’s demand.

Applications of Loft Water Tanks

These tanks suit a wide range of properties and settings where gravity-fed or reserve water storage is needed. For instance:

• Domestic homes — Supply bathrooms, toilets, and hot water cylinders in gravity-fed systems. Also useful in properties where mains pressure is insufficient, providing a steady reserve of water.
• Flats and shared housing — Regulate water supply across multiple units, ensuring consistent availability even during peak demand periods.
• Commercial buildings — Offices, schools, and small hotels use roof-space tanks to supply washrooms, kitchens, and heating systems. Compact sizing suits buildings with restricted installation space.
• Healthcare and hospitality — Hygienic design and WRAS compliance ensure safe, clean water for patients, staff, and guests in demanding environments.
• Rural and off-grid properties — Provide storage and gravity-fed supply where mains water is limited or unavailable. Reliable performance makes these tanks particularly valuable in remote locations.

Installation and Long-Term Value

Installing a loft water tank is straightforward. The tank passes through a standard loft hatch and sits on a flat, load-bearing surface such as a boarded loft floor or a purpose-built platform. Connect the inlet, outlet, and overflow using standard plumbing fittings. Furthermore, fit an insulation jacket if the tank does not already includeinsulation, especially in unheated roof spaces. Always follow current Water Regulations when connecting to the mains supply.

From a maintenance perspective, these tanks need very little attention. Inspect and clean the interior annually to prevent sediment build-up. Replace the lid seal if it shows signs of wear. Moreover, check the ball valve and overflow pipe regularly to ensure they operate correctly. Overall, a well-maintained loft tank gives decades of reliable service.

In terms of value, polyethylene tanks cost far less than equivalent metal or fibreglass alternatives. They install faster, weigh less, and need minimal upkeep. In short, our loft water tanks give you a cost-effective, hygienic, and dependable water storage solution for almost any domestic or commercial property.
