How much does it cost to install a pool?

The cost of swimming pool installation varies depending on the type, size, and materials:

  • Above-Ground Pools: Typically the most affordable option, installation costs range from £2,000 to £6,000, depending on size and design.
  • In-Ground Pools: Concrete or fiberglass pools range from £20,000 to £60,000, with larger or more luxurious designs exceeding this range.
  • Custom Features: Adding features like heating, lighting, or water jets can increase costs by £5,000 to £15,000.

Post your job on Rated People to receive tailored quotes from local swimming pool installation experts.

How long does it take?

Above-Ground Pools: These can often be installed within 1-3 days, depending on the complexity of the setup.

In-Ground Pools: Installation for in-ground pools typically takes 4-8 weeks, including excavation, construction, and finishing.

Custom Pools: Pools with additional features or intricate designs may take up to 12 weeks or more to complete.

How to keep your pool maintained

Proper maintenance ensures your pool remains clean, safe, and functional:

  • Regular Cleaning: Skim debris daily, vacuum weekly, and scrub pool surfaces to prevent algae buildup.
  • Monitor Water Quality: Test pH and chlorine levels regularly to maintain a healthy balance. Add chemicals as needed.
  • Check Filtration Systems: Clean or replace filters as recommended by the manufacturer to keep water circulating properly.
  • Winterize Your Pool: If you live in a cold climate, close your pool properly during winter to prevent damage.

Hiring a professional for regular maintenance can save you time and ensure everything is in top condition.

Other swimming pool installation FAQs

Do I need planning permission for a swimming pool?

In most cases, planning permission is not required for residential swimming pools, but always check with your local authority, especially if your property is in a conservation area.

What is the best material for an in-ground pool?

Concrete and fiberglass are the most popular options. Concrete is durable and customizable, while fiberglass offers quicker installation and lower maintenance.

Can I install a pool in a small garden?

Yes, small or custom lap pools can be designed to fit compact spaces, providing a luxurious feature even in smaller gardens.
