5 years on the tools taught us how often the phone rings at the worst possible time, mid job, up a ladder, in a panel. Sparkline exists to fix that, without pretending to be something it's not.
Missed calls don't announce themselves. No complaint, no email, just a caller who hangs up and rings the next name on Google. That's real money leaving quietly, and it happens to almost every small electrical business at some point in the day.
Sparkline is built strictly for UK electricians, not trades in general. It's designed to capture the job and get you the details, not to pretend to diagnose a fault or replace your judgement. Anything that sounds like a genuine safety issue gets a clear, consistent instruction: isolate at the consumer unit, don't touch it, help's on the way. No guessing, no overstepping.
Sparkline is in early testing with real UK electricians right now. If you'd like to be one of the first to try it, get in touch.
