Checker began with one simple job – getting gas engineers off the paperwork and back on the tools. Ten years on, it’s a full toolkit that quietly runs quotes, invoices, certs, diary, CRM and chasers for tradesmen up and down the UK.

The short version: we kept adding what tradesmen actually asked for, and never took anything out.
Checker started life as a way to bin the paper CP12 pad. That was it. One tool, one job – fill out a gas safety cert on your phone, email it to the customer, done.
Then the customers wanted a quote sending. So we built quotes. Then they wanted the invoice off the back of the job. So we built invoices. Then reminders for next year’s service. Then a diary that didn’t double-book you. Then a way to chase the customers who forgot to pay.
Every tool inside Checker exists because a working engineer picked up the phone and asked for it. Nothing was built for a boardroom. Nothing was built to look clever in a demo. If it doesn’t save you time on a wet Tuesday in February, it doesn’t ship.
Today Checker is one app that carries the whole job from first phone call to final payment – and it’s still built the same way. Engineers ring us, we listen, we build.
Numbers pulled from the average Checker user, compared to how they worked before switching.
Same engineer. Same customers. Same day rate. Just the software doing the boring bits in the background.
Three things we’ve never budged on since day one.
Every feature is designed with working engineers, not marketing folk. If it doesn’t help you finish earlier, it doesn’t get built.
One price, one plan, everything included. No add-ons, no per-cert fees, no surprise upgrades when your business grows.
Ring us, email us, message us. You get a proper answer from a proper person – no bots, no ticket queues, no offshore call centre.
We’re a small UK team of engineers and developers – the sort of setup where the person answering your support message is the same one who’ll build the fix. That’s on purpose. We’re not looking to become a giant tech firm; we’re looking to build the best possible tool for the trade, and stay close enough to our users to keep it that way.
If you’ve got an idea, a gripe, or a feature you’d love to see – drop us a line. It really does get read, and it really does get built.
Full access to every tool for 30 days. No card, no tie-in, no chasing you when the trial ends. If it fits, brilliant. If it doesn’t, no harm done.
