Top tips
Hiring a swimming pools, without the regret.
Four moves that separate a smooth job from a nightmare.
SPATA-registered installers only.
Swimming Pool & Allied Trades Association membership means insurance-backed installations and proper engineering. Without SPATA, your warranty is paper-thin.
Planning permission for outdoor.
Outdoor pools usually need planning permission. Indoor pools may need Building Regs and ventilation engineering. Don't excavate until consents are confirmed.
Heat pump beats gas for cost.
Modern air-source heat pumps run pools at 30–40% the cost of gas. Higher install, lower running. Most new pools spec heat-pump as default.
Cover + automation pays back fast.
Automated pool covers retain heat and stop evaporation. Pays back in heating + chemicals in 2–3 years.
