Koi Ponds

At Koi Water Garden, we specialise in koi pond design and construction across the UK. With over 40 years of infield expertise, our team builds ponds and filtration systems of the highest quality — from smaller bespoke projects to large-scale installations exceeding 250,000 gallons (1 million litres).

Our koi ponds are designed to be both visually stunning and highly functional. By combining natural-looking pond designs with the latest technology, we create environments that keep koi healthy and water crystal clear. Each project can incorporate advanced features such as:

Gravity-fed koi pond filtration systems

Custom pond filtration design tailored to your needs

Moving bed and water purification systems

Heating and specialist koi pond equipment

Because we also provide koi pond maintenance services, we understand the seasonal challenges pond owners face. Every pond is built with reliability, efficiency, and ease of care in mind.

Whether you’re looking for a custom koi pond system for your garden or a large professional installation, Koi Water Garden delivers expert craftsmanship, proven filtration, and long-term performance.
