Frequently Asked Questions
Everything you need to know about natural pool costs
Natural swimming pools in the UK typically range from £55,000 for a compact installation to £200,000+ for large estate pools with premium features. A medium-sized natural pool (around 10m × 6m) in the South East typically costs £100,000 - £130,000 including excavation, liner, planting, and basic landscaping.
Natural pools have higher upfront costs but significantly lower running costs. Over 15-20 years, natural pools often work out cheaper due to zero chemical costs (saving £500-1,200/year), lower energy use, and longer liner lifespan. Plus, you get a beautiful water garden year-round.
Key factors include: pool size and depth, site access and ground conditions, proximity to services, quality of materials and finishes, features like heating and lighting, regeneration zone design, landscaping requirements, and regional labour costs.
Annual maintenance for a natural pool typically costs £400-1,000, covering electricity for pumps (£150-300), plant management (£100-300), and occasional professional servicing (£150-400). This compares favourably to £1,500-3,000 for traditional pools including chemicals.
