HVAC Software UK — Dispatch, Schedule, Invoice in One App
3am, July, the chiller at a Newton Abbot care home drops. SLA says you're on site in two hours. Meanwhile a residential A/C install in Exeter starts at 8am, and a quarterly PPM walk at a Plymouth office complex needs slotting before Thursday. HVAC software UK shops need — multi-site dispatch, F-Gas register per asset, GBP flat pricing, offline engineer app. Built in Torbay, Devon, by people who've watched a real HVAC business run for 40 hours straight on a heatwave.
- ✓ F-Gas register built-in
- ✓ Multi-site PPM
- ✓ Offline mobile
- ✓ Flat GBP pricing
The dispatch board ServiceTitan ships, at one-tenth the price.
ServiceTitan is genuinely good HVAC software. It's also priced at roughly £500 per user per month plus an 18-month enterprise rollout, and the product expects North American conventions — QBO, US tax codes, dollar currency. For a UK HVAC shop with 5 to 25 engineers, the price gap is the point. Our HVAC software UK shops actually adopt — flat £599 a month for 5 engineers, £1,749 for 25, no contract. Same dispatch board. Same multi-site scheduling. Same per-asset history. Built in GBP, with VAT, CIS, and F-Gas treated as first-class concepts, not American afterthoughts.
Dispatch screen, one glance
Every engineer, every job, every SLA timer, one screen. Drag a job between engineers; both calendars update instantly, customer gets an SMS.
PPM scheduling
Quarterly walks, six-monthly chiller services, annual F-Gas leak checks — recurring contracts auto-create the calendar entries 30 days out. No manual diary work.
Asset register per site
One commercial building, twelve VRF cassettes, four split systems. Every asset tracked. Full service history searchable by serial number.
Per-asset F-Gas register. Auditor-ready.
UK F-Gas regulations require a record per refrigerant-containing system of every check, top-up, and recovery. Most HVAC software handles this with a tacked-on note field. Ours has a proper F-Gas register per asset: refrigerant type, charge weight, leak check result, engineer's F-Gas card number, date. Exportable to PDF on demand. When your annual F-Gas auditor turns up, two clicks and they have everything. No more spreadsheets, no more lost paper logs in the back of a van.
Refrigerant tracking by asset
R32, R410A, R454B — each charge logged against the asset, not the customer. When refrigerant pricing spikes you can see your exposure in one report.
Annual leak check reminders
Systems over 5 tonnes CO2-e need annual leak checks. Over 50 tonnes CO2-e, six-monthly. Auto-create the PPM entries — your engineer turns up before the regulation requires you to.
Migration from ServiceTitan
ServiceTitan exports JSON and CSV. We import customers, assets, PPM contracts, F-Gas history. Most ServiceTitan-to-OptitechAutomation migrations finish in a fortnight, mostly because ServiceTitan has so much. Worth it.
Migration from simPRO
simPRO's UK pricing scales fast as you add users. CSV export gets you out. We import customers, jobs, assets, recurring schedules. Most simPRO migrations finish in a long weekend.
Plant rooms. Server rooms. Roof voids.
HVAC engineers work in the worst possible places for phone signal. Underground plant rooms. Steel-clad server rooms. Roof voids two storeys above a steel frame. Most HVAC software pretends none of this matters. Ours doesn't — the worker app is offline-first. The F-Gas reading, the asset photo, the SLA tick, the customer signature all save locally. When the engineer climbs out to a signal pocket, sync happens in 30 seconds. The owner dashboard always shows what's pending sync, so you can't lose a job to a flat battery in a basement.
£599 a month. No quotes, no calls.
The other HVAC software UK shops look at — ServiceTitan, simPRO, BigChange, Commusoft — all want a call before they show a price. We don't. £599 a month flat for up to 5 engineers. £1,749 for up to 25. £3,599 unlimited. GBP, monthly, cancel any time. No setup fee for the first HVAC shop in your UK county. Read the pledge in writing in your contract.
Not "contact us." Not "we'll get back to you." Numbers, plain.
Pounds, every month. No multi-year commit. No US dollars.
Cancel from the dashboard. Data exports the same hour.
I'm Cristian, in Torbay, Devon. I built HVAC software because a heating engineer mate ran an SLA across nine commercial sites on a spreadsheet.
He missed a quarterly walk because his diary fell out of his van. The customer didn't fine him — that time. The next contract round, they didn't renew. He'd lost £42,000 of recurring revenue from a missing diary entry. So we built a system where recurring PPM contracts auto-create the calendar entries, send the customer a "we'll be there Thursday" SMS, and the engineer's app shows the SLA timer ticking on the screen. F-Gas register, asset history, per-engineer F-Gas card numbers, offline-ready. All for £599 a month flat. No multi-year contract. No setup fee for the first HVAC shop in your county.
