Owning a hot tub should be about total relaxation, not worrying over maintenance schedules or technical error codes. To help our Southport customers keep their spas in peak condition, the technical team at Hot Tub Southport has compiled this guide to the most frequently asked questions regarding service, care, and energy efficiency.

Servicing & Hygiene

How often does a hot tub actually need a professional service? For most domestic owners, a Refresh Service  is recommended every 3–4 months to reset hygiene levels. However, a comprehensive Annual Technical Service is essential once a year to inspect the mechanical and electrical integrity of the spa.

I use chlorine; do I still need a “Deep Clean”? Yes. Chlorine kills free-floating bacteria but cannot easily penetrate biofilm—a sticky, protective layer that forms inside the internal pipework. Our Deep Clean Service uses specialised professional-grade flushes to strip this biofilm away, ensuring your water is truly safe.

Energy & Efficiency

Why is my electricity bill so high? The most common cause is heat loss through the cabinet. If your hot tub isn’t properly insulated, the heater has to run constantly to maintain the temperature. At Hot Tub Southport, we provide Insulation Packages starting from  that are designed to save you at least 50% on running costs.

Will insulation damage my pumps or heater? Quite the opposite. By trapping heat effectively, your pumps and heater run less frequently. This reduces mechanical strain, leading to fewer breakdowns and a longer lifespan for your equipment.

Technical & Safety

What is included in the Annual Service? This is our most thorough technical health check. It includes a 26-point safety report, electrical integrity testing, and a full mechanical inspection. Critically, we also perform the removal and vacuuming of suction covers to prevent hair and limb entrapment hazards.

My hot tub is showing an error code—what should I do? Common codes like “FLO,” “DRY,” or “HL” usually indicate an issue with water flow or the heater. Before calling us, check that your filters are clean. If the code persists, it may indicate a pump or sensor failure, and you should contact us for a diagnostic visit.

Holiday Let Compliance

I rent out my property; do I need a special contract? Yes. Holiday lets are subject to HSG282 health and safety guidance. This requires more rigorous water management and documented safety checks than a standard home tub. We offer tailored maintenance contracts to ensure you remain fully compliant and your guests stay safe.
