Chairman and CEO Fred Voccola unveils THUNDER alongside his annual briefing on the state of the field service trades. Dex Hunter-Torricke, Mark Zuckerberg's former speechwriter and global communications lead for Google DeepMind, headlines day two.
LONDON, UK – 14 August 2026 – Simpro and BigChange, the field service management brands of Simpro Group, today opened the full agenda for Simprosium London 2026, taking place 22–23 September at the Hilton London Metropole. Hundreds of leaders from field service trade businesses across the UK and Europe will attend.
The average field service trade business earns 6% net profit. The businesses that run well earn 24%. The gap isn't effort, its execution capacity. Two days in London are built to close it.
Simprosium London 2026: The State of the Trades, and What Comes After RAIN
Chairman and CEO Fred Voccola opens with his annual briefing on the field service trades: where the market stands, the pressures reshaping it (labour, cost, compliance, cash), and the group's mission to move the two numbers that decide whether a trade business thrives or merely survives, profitability and efficiency.
Within it comes the first public reveal of THUNDER, the next chapter of Simpro Lightning and BigChange Lightning, the shared AI platform behind both brands. Lightning put AI in the hands of trade businesses to answer their questions. THUNDER (the next phase) is what happens when the platform starts doing the work. It will be revealed on the London mainstage on the morning of 22 September, then unpacked across two days of sessions.
"The field service trades keep this country running, and almost nobody builds technology with them in mind," Voccola said. "Our job is to hand a 12-van business the operational advantage that scale has always handed the biggest players. But the other half of it is the room itself — hundreds of operators comparing notes and telling us what to build next. That's not a conference. That's a community."
Meet Cooper and the Digital Field Service Workforce Behind the Lightning Platform
At the centre of Simpro Lightning and BigChange Lightning is Cooper, the AI that learns how a business actually operates. Cooper answers questions in plain language, takes action to streamline operations, and coordinates the Digital Workforce: the AI agents that chase overdue invoices, re-engage dormant customers, answer inbound calls and fill open slots in the schedule, at a fraction of the cost of a full-time hire.
Cooper isn't a chatbot bolted onto a menu. He's a partner who knows the business, does the work nobody has time for, and gets better the longer he's around. Fitting, given he's named after a dog. Chief Product and Business Development Officer Raffi Tchakmakjian and the product team follow Voccola on the mainstage with a live walkthrough.
AI Field Service Software Takes the Simprosium London Stage
AI is moving faster than any technology the trades have had to absorb, and most owners are being asked to form a view on it while running a full schedule. The answer runs on two fronts. Inside the platform, Cooper and the Digital Workforce turn AI into work that gets done rather than features that get demoed. Outside it, Simpro and BigChange are integrating with the global leaders defining the frontier of AI, so customers inherit that progress rather than chase it.
Dex Hunter-Torricke, who spent a decade shaping how the world's largest technology companies talked about breakthrough products, opens day two with The World in Sight, a forecast of the shifts that will reshape work over the next 10 to 20 years.
Simprosium London Sessions for the Field Service Trades
Three concurrent tracks run across both days, covering the current and future roadmap for Simpro, for BigChange, and for the operational problems every field service business shares. The State of the Trades 2026 delivers an honest read on the market, combining independent UK research with platform data from 24,000 businesses.
Day two brings the M&A in Trades Summit: Voccola on the state of the market, Chief Financial Officer Ashley Mehlman on the pitfalls nobody warns you about, and a panel of trade business owners who have actually bought and sold. Also on the agenda: three customers running the Lightning platform for 120 days, telling the unedited truth about it.
Two Days That Don't Feel Like a Conference
Day one closes with a Casino Night in the Expo Hall. Day two closes with Trade-Family Fortunes: Trades v Trades on the mainstage. The people who run trade businesses have sat through enough slide decks, so they get to compete for prizes.
Simprosium London Kicks Off a Global Field Service Series
