Adding a swim spa to your home isn’t as simple as plugging it in. Proper installation requires a solid foundation, electrical wiring and sometimes specialised equipment to position the unit. These costs are important to factor into your budget.

Preparing a solid base

A swim spa typically weighs several tonnes when filled with water and occupants, so it needs a strong, level surface. The most common options are:

• Concrete pad: A reinforced concrete slab is the gold standard. Expect to pay £1,000–£3,000 depending on size, thickness and site preparation.
• Reinforced patio or deck: Existing patios or decks must be reinforced to support the weight; costs vary but can be lower if you already have a suitable area.
• Sunken installation: Some owners choose to sink the spa into the ground or a pit surrounded by decking. Excavation and retaining walls add significant cost.

Electrical installation

Swim spas need a dedicated hard‑wired electrical connection. An electrician will run armoured cable from your consumer unit (fuse box) to an external isolator near the spa. Costs vary but typically range £500–£1,200 depending on distance and amperage (30 amp for small units, 45–63 amp for larger models). Always hire a qualified electrician to comply with regulations.

Delivery and positioning

Swim spas are delivered in one piece and may require a crane or Hiab to lift them into position. Standard delivery and placement usually cost £500–£800. If access is difficult – over a house or through tight gardens – you may need a specialist crane, which can add £1,000 or more.

Additional extras

• Heat pumps: Installing an air source heat pump can cut running costs but adds £1,000–£2,500 to the initial outlay.
• Cover lifter and steps: Good cover lifters, steps and handrails make using your spa easier and safer; budget £300–£600.
• Landscaping and enclosures: Creating an attractive spa area with decking, fencing or a gazebo can add thousands but enhances privacy and usability.

Summary

While swim spas cost much less than a full‑size pool, installation costs can be significant. Plan for a sturdy base, electrical hookup, delivery, potential crane hire and optional extras like heat pumps or enclosures. Investing in proper installation will ensure your spa is safe, efficient and ready to enjoy for years.
