Best PAT Testing Software and Apps for UK Electricians (2026)
A 2026 comparison of PAT testing software and apps for UK electricians, covering asset registers, retest reminders, certificate output, offline reliability and price across eight platforms including Checker, Tradify, Commusoft and Powered Now.
Best PAT Testing Software and Apps for UK Electricians (2026)
Portable appliance testing creates its own paperwork problem: pass and fail results for dozens or hundreds of individual appliances, a retest date attached to each one, and a certificate that needs to hold up if a landlord, facilities manager or HSE inspector ever asks to see it. This guide compares the software UK electricians use to run PAT testing, from tools with a named PAT certificate template to the wider electrical compliance platforms PAT commonly sits inside, on asset registers, retest reminders, certificate output and price.
By Daniel Sedgwick, Founder of Checker and former gas engineer
This guide compares the tools UK electricians and PAT testers most often shortlist for portable appliance testing work: platforms with a named PAT certificate as standard, and the wider electrical compliance apps PAT commonly sits inside alongside EICR, Minor Works and CP12 gas safety records. We checked the same things on every tool: whether PAT is a named certificate template or something you would have to build yourself, whether appliances sit in a standing asset register or a one-off test log, whether a retest date triggers an automatic reminder, how each handles offline capture, and what it costs per user per month.
Key takeaways
- Tradify, Commusoft, Powered Now and Fergus each name PAT as a standard certificate template; Joblogic and simPRO do not confirm it, and ServiceM8 relies on a general form builder.
- An asset register, a standing record per appliance, differs from a one-off test log, and matters most on repeat-visit sites with dozens of appliances to track.
- Checker does not currently generate a PAT certificate; it covers EICR, job management and automated reminders instead, and its Annual Service Reminder can still prompt a yearly PAT round.
- Offline capture is inconsistent: Powered Now, Checker and ServiceM8 confirm it directly, while Tradify has no offline mode at all.
- Per-user pricing spans roughly £11 a month (Checker, without PAT) to £45 or more (Joblogic), and several vendors require a demo call for any figure.

What PAT testing software needs to cover
PAT testing raises questions a general job diary does not always answer. Six things are worth checking before you commit any tool to this work:
- An asset register, not a one-off log. Each appliance should hold a standing record, an asset ID, location and class, so next year’s visit updates the same item.
- Retest-due reminders. The software should flag automatically when an appliance is due, not rely on someone checking a spreadsheet.
- A certificate that holds up. Landlord, facilities manager or HSE inspector, the output needs to read as a proper record with a clear pass or fail.
- Fit with wider electrical compliance. Most electricians doing PAT also produce EICRs and Minor Works certificates, so one job record for all of it saves admin time.
- Mobile and offline capture. Testing happens in server rooms and basements with patchy signal, so results should save on the device and sync later.
- Price and contract terms. Monthly per-user pricing with no lock-in suits a growing PAT volume; a demo-only annual contract suits an established operation.
Tradify
Tradify is a job management platform widely used by small UK trade teams, including electricians, and it is one of the few tools here naming PAT specifically. Its UK electrical certificate set, EICR, EIC, PAT and Minor Works, sits on the Pro tier at £37 per user per month, covering both certificate types from one subscription.
There is no dedicated asset register described on Tradify’s own site; PAT results are stored against the job rather than a standing register of assets. Tradify also has no offline mode at all, so a live connection is required throughout a PAT round. Accounting sync covers Xero and QuickBooks two-way and Sage one-way.
Checker
For electricians, Checker currently generates EICR electrical condition reports from the same job record as the quote and invoice, plus CP12 gas safety records for firms doing combined gas-and-electric work. Its founder, Dan Sedgwick, is a former gas engineer, and the platform he built now covers UK gas, electrical, plumbing and heating trades, with close to 19,600 businesses using it.
For PAT testing specifically, Checker does not yet generate a dedicated certificate, a genuine gap against certificate-led competitors such as Tradify, Commusoft, Powered Now and Fergus. What it does offer is somewhere to hold the wider job and customer record a PAT round sits inside: results can be logged as job notes against a customer’s history, and the Annual Service Reminder, firing automatically around eleven months after a job record is created, gives a workable prompt for a yearly PAT round.
Sub-users sit under one master-user login, Appointment Reminders and a Quote and Invoice Chaser handle follow-up automatically, and accounting syncs two-way with Xero, QuickBooks and Sage. Pricing runs Lite at £10.99, Pro at £19.99 and Pro Plus at £25.99 a month, all plus VAT, with no lock-in contract. Checker suits electricians who want EICR and job management with automated chasing, and are willing to log PAT separately until a dedicated certificate ships. Start at my.checker.app/register.
Commusoft
Commusoft targets established, multi-engineer businesses rather than sole traders, with dispatch and scheduling for teams working several sites at once. PAT is native alongside EICR, Minor Works and CP12 as named electrical templates, with offline certificate creation and digital signatures on mobile, a credible option for facilities-style contracts covering many properties. There is no self-serve price, only a demo call: it is built for businesses with six or more staff.
Joblogic
Certification modules come bundled into Joblogic’s wider platform, though its own site never breaks PAT out as a separately named template, so confirm that before assuming it is covered. Where it has genuinely built a name is with multi-site electrical and gas contractors and the fire-and-security trade, both running recurring maintenance work rather than one-off jobs.
£45 per user per month for signing up annually, monthly payment is also allowed, and past 50 users Premium and Enterprise step up to a bespoke price instead of a listed one. It suits larger contractors running recurring PAT contracts more than a sole trader doing occasional testing.
ServiceM8
ServiceM8 is a mobile-first job management app used by small trade businesses, including electricians, running quoting, invoicing and a job diary from a phone. Offline working is genuinely confirmed: logging details, notes and photos with no connection, syncing once reconnected, suiting PAT rounds in basements and plant rooms.
What it does not offer is a named UK PAT certificate template. ServiceM8 markets a general custom form builder rather than pre-built statutory forms, so a PAT certificate and any asset register would need building as a custom form. Pricing runs free to £269 a month by job volume, ex VAT, with no contracts.
Powered Now
Powered Now is a UK quoting, invoicing and forms app aimed at trades that want paperwork out fast, and it carries one of the broadest named electrical certificate libraries here. PAT sits alongside EICR, domestic and commercial EIC, MEIC, Electrical Danger Notices and Emergency Lighting templates, plus CP12 and CP2 gas templates, though certificates are gated to the Professional plan and above rather than the base Business plan.
Its offline claim is confirmed directly by the vendor, full offline working with data syncing once a connection returns. Pricing runs £28, £32 and £40 per user per month, ex VAT, with the certificate library unlocking only on Professional or above.
Fergus
Fergus began as a job management platform for trades in New Zealand and Australia and has since built a genuine UK presence, with a Manchester office and UK supplier integrations including City Plumbing, Wolseley, Screwfix and CEF. Job costing is its particular strength, tracking labour and materials so a PAT contract’s real margin is visible rather than estimated afterwards.
PAT is included in a free compliance-certificate add-on alongside CP12, EIC and Minor Works, though Fergus does not publish a certificate literally named EICR, worth checking if you need that template too. UK pricing is in GBP: Essentials from £39 a month, Professional from £45, and a custom quote for Enterprise at ten or more users.
simPRO
simPRO serves larger commercial trade businesses, electrical, fire and security, and HVAC contractors managing multi-site contracts and maintenance schedules. It is a heavier system than most tools here, built for established operations rather than a sole trader running occasional PAT visits.
Specific PAT certificate templates and asset-register functionality are not confirmed on simPRO’s own UK site, and neither is self-serve pricing, so verify directly with the vendor, including retest scheduling, before shortlisting it for PAT work.

Frequently asked questions
What should PAT testing software actually do for an electrician?
At minimum, it should hold a record for every appliance tested, flag automatically when a retest falls due, and produce a certificate that stands up if a landlord, facilities manager or HSE inspector asks for it. The stronger tools also fit that PAT record alongside a business’s other electrical compliance work, EICR and Minor Works included, rather than running as a standalone app nobody else opens.
Does Checker generate PAT certificates?
Not currently. Checker generates EICR reports and CP12 gas safety records from the same job record as the invoice. Its Annual Service Reminder can prompt a yearly PAT round, but a standalone PAT certificate isn’t part of the product today. Electricians whose main need is PAT paperwork should weigh that against Tradify, Commusoft, Powered Now and Fergus, which all include a named PAT template.
What is a PAT asset register, and why does it matter more than a single test record?
A one-off record just logs a pass or fail on the day. An asset register keeps a standing entry for each appliance, typically an asset ID, its location and class, so the next visit updates the same item instead of creating a fresh record. That matters most on repeat-visit sites, offices, landlord portfolios and schools, where dozens of appliances need tracking year on year rather than being rediscovered.
Which UK trade software includes PAT certificate templates as standard?
Tradify, Commusoft, Powered Now and Fergus all confirm a named PAT certificate template on their own sites, though access varies: Tradify gates it to Pro, Powered Now to Professional and above, and Fergus includes it in a free add-on. Joblogic and simPRO reference broader certification tooling without naming PAT, and ServiceM8 relies on a general form builder instead.
How often should retest reminders fire for portable appliances?
There’s no single legal interval. HSE guidance treats PAT as part of a wider risk-based maintenance regime, with typical retest frequencies ranging from a few months for construction site equipment to several years for low-risk office kit. A fixed annual reminder is a reasonable default for small businesses, but software that lets you set a different interval per asset or category suits a growing asset register better.
