Swimming Pond vs Natural Pool: Cost Differences
You might wonder whether a swimming pond costs less than a natural swimming pool. In practice, the terms are often used interchangeably in the UK. A swimming pond typically refers to a more naturalistic design, while "natural pool" can include contemporary or formal styles.
Swimming pond cost tends to sit at the lower end (£60,000-£100,000) due to simpler edging and more informal planting. Formal natural swimming pools with architectural details typically cost more (£90,000-£200,000+).
What Affects the Price?
Several factors influence your final investment:
1. Garden Access
Difficult access for machinery can add £5,000-£15,000 to costs. Narrow side passages or sloped terrain require specialist equipment. Understanding the best time to build helps you plan around these challenges.
2. Soil Conditions
Rocky soil or high water tables require additional excavation work. A site survey helps identify potential challenges early.
3. Size and Depth
Larger pools require more liner, more plants, and larger filtration systems. Deeper swimming areas (2m+) add complexity. The construction materials you choose also significantly impact the final price.
4. Design Complexity
Custom shapes, integrated features, lighting schemes, and architectural details increase costs but create stunning results. Avoiding common mistakes during planning saves money long-term.
Running Costs
Unlike chlorinated pools, natural swimming pools have minimal running costs:
- Electricity: £200-400/year for pumps
- Maintenance: £300-500/year for plant care and water testing
- No chemicals: Save £500+/year
- Heating: (optional): £400-800/year
- Insurance: £50-150/year additional premium
