Pond Liner FAQ

What is the best pond liner to buy in the UK?

The best pond liner depends on your pond type. EPDM rubber is the most popular for garden and koi ponds due to its flexibility and fish-safe certification. HDPE is best for large or commercial ponds. Butyl offers the longest lifespan with a lifetime guarantee. For budget ponds, LDPE or PVC are excellent value.

How do I calculate what size pond liner I need?

Use the formula: Length + (2 × depth) + 0.5m overlap = liner length. Width + (2 × depth) + 0.5m overlap = liner width. For example, a pond 3m long × 2m wide × 0.8m deep needs a liner approximately 5m × 4m. Use our free pond liner calculator for an instant result.

Are your pond liners fish safe?

Yes — all our pond liners are fish safe. Our EPDM liners are manufactured to EPDM-45 standard, which is certified safe for fish and aquatic life. Our HDPE, PVC, and Butyl liners are also non-toxic and safe for koi, goldfish, and wildlife ponds.

How long do pond liners last?

Pond liner lifespan varies by type: PVC liners typically last 15–30 years, LDPE 15–40 years, HDPE 25–40 years, EPDM 25+ years, and Butyl and Polyex liners come with a lifetime guarantee. All our liners are UV stabilised to prevent degradation from sunlight.
