Legionella testing is a legal duty for many businesses, but arranging it usually means booking an engineer and waiting. Legionella Sampling set out to make it something you can do yourself: order a kit, take a sample, post it, and get a clear result back.
The ChallengeWhere Legionella Sampling Started
Legionella Sampling needed to turn a technical, compliance-heavy process into something a customer could complete on their own, and run the whole operation behind it without drowning in manual admin. That meant selling and shipping test kits, tracking each physical sample from customer to lab, taking one-off and recurring payments, and turning lab data into results a non-expert can actually understand and act on.
Our ApproachWhat We Did
E-commerce and subscriptions
We built the store and checkout on Stripe, including subscriptions for customers who need to test on a regular schedule, so recurring compliance testing effectively runs itself.
Kit fulfilment and QR tracking
Every kit is tracked through the process with QR codes, tying a physical sample back to the right customer and order, so nothing gets lost between the doorstep and the lab.
Results interpretation and delivery
We built automated results interpretation and delivery, with AI integration, so raw lab data becomes a clear, plain-English result and recommendation delivered straight to the customer.
One platform, end to end
The whole journey, from order and payment to sample, lab and result, lives in a single web app: simple for the customer, and manageable for the Legionella Sampling team.
What Changed
Legionella Sampling now runs as a single, self-service platform. Customers order and pay online, samples are tracked end to end with QR codes, and results are interpreted and delivered automatically. What used to need an engineer visit is now something a business can do itself, and the operation behind it scales without piling on manual work. The platform is live at legionellasampling.co.uk.
