PAT testing without the evening paperwork.
Record every appliance on your phone. The report and certificate are built the moment you finish, and they're waiting in your customer's portal. Next year's retest is already on the list.
No card needed. From £19 + VAT a month for one engineer, with everything included.


- Built by a working PAT tester
- Every feature on every plan
- UK hosted, UK support
- Monthly, cancel any time
The testing is the easy bit.
It's everything around it that eats your week.
Certificates at the kitchen table
A full day on site, then an evening copying readings off the tester and into a template.
Retests nobody remembered
Last year's customers don't ring you. If you don't chase them, someone else gets the job.
"Can you send last year's certificate?"
Digging through emails for a PDF, and checking the bank before you dare send anything.
From booking to next year's booking.
Book it
Pick the site and a date. The schedule knows the drive times, and the job goes straight to the engineer's phone.
Test it
Record each appliance in the app: class, readings, pass or fail, with a photo of anything that fails.
Get paid
The certificate lands in the customer's portal. Confirm their payment and they get their login to download it.
Go back next year
Six weeks before the retest, a reminder is drafted for your approval, and customers can pick a date themselves.
Built for the job, not the office.
Big buttons for Class I, Class II, IEC and extension leads. Pick lists for items, rooms and fail reasons. Readings in, next item, done.
- Today's jobs with the address, contact and notes
- Earth, insulation and leakage readings, fuse and load
- Visual-only items and failed visuals, with reasons
- Photos of failed appliances, attached to the result
- Results stay on the phone until they're safely uploaded
No more "can you resend the certificate?"
Every customer gets their own login. They see every job by year, and download each report and certificate themselves.
- Documents unlock as soon as you confirm payment
- Companies with many sites download the lot in one go
- Customers see when their next test is due, and book it
Next year's work, already lined up.
Every job knows when its retest is due. Nothing goes to a customer until you say yes.
- Reminders drafted six weeks before a retest is due
- One list to approve: send all, send or skip
- Book the retest in a click, or mark who went elsewhere

A trust's schools or a chain's shops, grouped under one company.
Customer sign-off
Ask for a signature at the end of the job, on every job or just the ones that need it.

A photo ID card in the app, so customers know who's on site.
Your year at a glance
Turnover for the tax year, what's outstanding and what's overdue.
Made by a PAT tester, for PAT testers.
My Mate PAT started as the system a working PAT testing company in the South East built to run itself: schools, surgeries, pubs, offices and shops, thousands of appliances a year.
Every feature was added because a real job needed it. It's still used on site every week, so when something is awkward on a Monday morning, it gets fixed.

Questions
Does it work with my PAT tester?
Yes. On any tester you type the readings into the app, with big buttons and pick lists to keep it quick. The app also has direct links built in: a Bluetooth link for Seaward PrimeTest and Supernova on Android, and result-file import for Seaward Apollo, Kewtech KT77 and KT79, and Megger PAT400. These have not yet been tested with real testers, so for now plan on typing readings in. Tell us which tester you use and we can try it with you.
How do my customers get their certificates?
When the engineer finishes, the report and certificate are built and saved to the customer's portal. When you confirm their payment, they're emailed their portal login, and from then on they can download every report and certificate you've done for them.
Do I need a card to try it?
No. The 14-day trial needs only your name, business name and email. Add a card when you decide to carry on. Nothing you enter during the trial is lost.
Who owns the data?
You do. Your customers, jobs and results belong to your business. Each business's data is kept separate from every other's, and you can have a copy whenever you ask. See our privacy policy.
