“Replaced three separate apps with Elec-Mate. Certs, quotes, and scheduling all in one place.”

Your minimum charge is the lowest amount you can charge for a visit without losing money. It is the price floor for short callouts, quick remedials, minor fault finding, and small domestic jobs that might only take 20 to 40 minutes on site but still consume a meaningful part of your day.
Many electricians think in terms of the task itself: "It is only changing a light fitting" or "it is just one socket fault." The problem is that the task duration is only part of the cost. There is travel, parking, loading materials, writing up the job, invoicing, and the dead time between appointments. Your minimum charge exists to cover all of that.
If you already know your monthly cost base from the break-even calculator, the minimum charge is the practical number that stops you accepting small jobs below that cost floor.
Use Elec-Mate to calculate your real minimum charge, then carry it straight into quotes and invoices so the number is actually used on site.

A proper minimum charge is not just "one hour labour." It needs to absorb all the hidden cost that comes with showing up.
If you miss any of those, your "small" jobs become the visits that fill the day but do not move the business forward.
Start with your target effective hourly rate, then add the non-productive time and direct visit costs around it. For many electricians, a one-hour on-site task actually occupies 90 minutes to two hours of the working day once travel and admin are included.
A simple method is:
Minimum Charge = Labour Block + Travel Cost + Overhead Allocation + Consumables + Profit Margin
For example, if your target charge-out rate is £65 per hour, the visit consumes 90 minutes of real time, travel/parking costs are £12, consumables are £5, and you want a modest profit buffer, a minimum charge of £95 to £110 may be far more sensible than charging "just one hour".
Use the hourly rate calculator to get the labour rate right first, then use this tool to stop short jobs slipping under it.

Reactive work is especially dangerous to underprice because the job often includes diagnosis, discussion, and a second trip for parts. A client may hear "quick job", but your business still has to absorb the full visit cost. A clear minimum charge prevents awkward conversations and protects your margin before the job even starts.
It also makes quoting easier. If the first line of every small job is built on a sensible minimum charge, your team stays consistent and the client gets a clearer explanation of what the visit actually covers.
Calculate your price floor once, then reuse it across callouts, quotes, invoices, and remedial visits inside Elec-Mate.
Try it free for 7 daysMost electricians do not lose margin because of one huge pricing mistake. They lose it through dozens of underpriced short visits across the month.
If you want pricing to improve materially, build the number into the workflow rather than keeping it as a note in your head. That is when it starts changing quote quality in the real world.
Bring fixed costs, vehicle costs, and working-pattern assumptions into the minimum-charge calculation instead of guessing.
Set a minimum charge that covers costs and still leaves margin instead of merely breaking even.
Use the number in your quotes and invoices so your calculated minimum charge becomes a real business rule.
Keep pricing consistent across your team so different operatives do not undercut the same type of visit.
Account for the real time a short visit consumes, not just the minutes spent with tools in hand.
Pair the minimum-charge tool with break-even, hourly-rate, and profitability pages to strengthen the whole pricing workflow.
Verified reviews from the UK App Store.
Elec-Mate is my go to app for business and electrical work. It's feature rich without feeling cluttered. A true all in one app for quotes, certs, calculations, RAMS, EICRs, and more. I use it every day without fail, and it makes my workflow much smoother since I'm not jumping between apps anymore. The price-to-feature ratio is excellent. Any issues I've had, the developer responds within the hour and usually fixes them the same day. 100% recommend.
I've used the app and the web based version for a while now and it's well worth the investment. If you're an apprentice or experienced Spark give it a go, you won't be disappointed.
I've been using Elec-Mate for a while now, and honestly, it's one of the best apps I've ever downloaded. Every aspect of it feels thoughtfully designed, from the clean and intuitive interface to the powerful features that make everything so easy to manage. It's clear that a lot of care and attention went into building this app, and it shows in every detail.
