WorkProof is the job-site app for air-conditioning installers. Photos, walkthrough videos, markups, plans, F-Gas and commissioning, all logged against the job, from the first site visit to sign-off.

Every photo, clip and note is stamped with who, where and when, filed against the job, and there in the office before the engineer is back in the van.
Photos · Video walkthroughs · Voice notes · Markups
Filed to the job. Shared with the office. Kept for good.

One flow for every install. Film it, photograph it, mark it up, hand the office a report. No WhatsApp threads, no camera roll archaeology.
Film a walkthrough, scan the room, tap in the customer. The AI drafts the survey and the engineer's brief from the footage.
Photos, clips and voice notes straight to the job. Arrival and departure logged automatically from the site geofence.
Arrows, circles, measurements and pipe routes on any photo or plan. Calibrate a plan once and every run is in metres.
Commissioning sheets, F-Gas records, photo reports and customer updates, signed on the phone and sent as PDF.




Built on real installs, not in a boardroom. Big buttons, few taps, works with gloves on and no signal.
Engineers work from the phone. The office works from the browser. Same jobs, same photos, same chat, updated the second anything happens.
Shoot from inside the job. Unlimited walkthrough recording, captions by voice, tags and before/after pairs.
› stamped · queued offline · synced
Pen, arrows, boxes, text, measure and pipe-route tools on photos and PDF plans. LiDAR room scans become to-scale plans.
› pipe run 7.4 m · trunking 3.2 m
Geofenced sites stamp arrival and departure automatically. Missed bookings get flagged the next morning.
› 08:12 arrived · 16:40 left · confirmed
A chat per job with @mentions on photos. Customers get "we're on our way" and day-before reminders by SMS and email.
› reminder 17:00 · on-our-way · done
Invoices and receipts scanned into the job costs, customers looked up from Xero, PDFs shared anywhere.
Generic job apps stop at photos. WorkProof knows what an F-Gas record is, what a commissioning sheet needs, and which unit is due a service.





Dashboard, dispatch board and jobs table in any browser. Drag a job to another day or engineer, and their phone updates.
Who's where, what's booked, which jobs have gone red and why.
Drag and drop bookings between days and people. Conflicts show before they happen.
Stage, health, costs and margin for management. Engineers only see what they need.

I got tired of scrolling through 4,000 photos on a Sunday night to prove we'd done the job.
— The founder, an air-conditioning installer who still goes out on installs
WorkProof started as a tool for one installation company that had outgrown WhatsApp groups and camera rolls. Every feature was built on a real job, tested by real engineers, and thrown out if it needed more than a couple of taps. It runs a working HVAC business every day. Now it's opening up to yours.
Early-access members lock in these prices for 12 months. Cancel any time. Prices exclude VAT.
One engineer. Everything on the phone, unlimited jobs and photos.

Early access is free while we onboard the first companies. You'll get a month's notice before billing starts.
The core is the same for every trade: jobs, photos, video, plans, chat, calendar. Each edition adds the forms and registers that trade actually uses.
Splits, VRF, heat pumps. Units register, F-Gas, commissioning, breakdowns.
Circuit schedules, test results, EICR photo evidence, consumer unit records.
Boiler commissioning, Benchmark, gas safety records, cylinder registers.
Stage photos, snagging lists, drawings on site, subcontractor sign-off.
Yes. Photos, clips and notes queue on the phone and upload when you're back in range. Nothing is lost if the app closes or the phone restarts.
iPhone (iOS 16 or later) and Android 10 or later. LiDAR room scans need an iPhone Pro; other phones measure rooms by tapping corners on the floor.
No. The office works from any browser at app.workproof.site with the same login. Phones for the field, browser for the desk.
Yes. Your jobs, photos and records belong to your company. Export PDFs at any time, and ask for a full export if you ever leave.
Early-access companies keep the prices shown for 12 months from the day billing starts. You get a month's notice before that.
Company plans include an import from a spreadsheet or your current job system. Smaller teams can add jobs in a few taps each.
We're onboarding HVAC companies a few at a time so every one gets set up properly. Leave your details and we'll be in touch within a couple of days.
