How It Works

Knowing your hot tub or pool water is safe shouldn't require a science degree or a commercial testing contract. Our kit gives you professional microbiological analysis from a UKAS-accredited laboratory, delivered to your door and back with no fuss.

Here is how it works.

1. Order Your Kit

Your kit arrives containing everything you need: a swab, clear step-by-step instructions, and prepaid return packaging already addressed to our UK laboratory. Nothing else to buy, nothing else to organise.

2. Take Your Sample

Follow the simple instructions to collect your swab from your hot tub or pool. The process takes just a few minutes and requires no specialist equipment or knowledge.

Important: Take your sample Monday to Thursday and post it the same day. This ensures it reaches the laboratory within the required timeframe for accurate analysis.

3. Post It Back

Drop your sample in any post box using the prepaid packaging included in the kit. No trips to a post office, no courier to book.

4. Receive Your Results

Your professional results report will be emailed to you within a few working days of your sample arriving at the laboratory. Produced by qualified microbiologists, it tells you clearly what was found and at what levels. If any issues are identified, practical next steps are included so you know exactly what to do.

What We Test For

Every kit tests for the key bacteria associated with hot tub and pool illness:

  • E. coli
  • Total coliform bacteria
  • Pseudomonas aeruginosa

These are the organisms most commonly linked to hot tub folliculitis, ear infections and gastrointestinal illness in bathers - and the ones most likely to be present even when your water looks and smells completely normal.

For Airbnb and Holiday Let Hosts

If you rent your property commercially, you have a legal obligation under HSG282 and the Health and Safety at Work Act 1974 to ensure your hot tub water is microbiologically safe for guests. HSG282 compliance requires microbiological testing carried out using a UKAS-accredited method. For compliant testing visit our commercial service at bestwatermonitoring.co.uk.
