- Hydration-break scheduler that respects Working Time Regulations
- Audit-ready PDF log of actions taken for HSE inspections
HSE guidance is tightening around heat in the workplace, and the late-July forecast has employers asking whether their existing procedures actually cover the new normal.
HSE has formal heat-stress guidance and 2025–2026 press cycle around UK heatwaves is real (TUC statements, law-firm briefings, Parliament research briefing), but the cited Google Trends signal is weather-curiosity not B2B search intent, and no evidence SMBs are actively shopping for dedicated heat-compliance tools.Temperature in the workplace: Heat stress - HSE ↗Working in hot weather: What does the law say? - Commons Library ↗
Market is already crowded: EnviCourse sells a HSE six-factor Heat Risk Assessment Tool, iProtectU offers a free workplace heat plan, SmartQHSE has a heat-stress module and IntegraRisk covers heat in its risk-assessment suite — all targeting UK employers with overlapping functionality.Workplace Heat Risk Assessment Tool — HSE Six-Factor Framework (EnviCourse) ↗Free Workplace Heat Plan - iProtectU ↗Heat Stress Management Software | SmartQHSE ↗
Existing competitors sell one-off assessment templates for low single-digit to ~£30 rather than recurring dashboards; UK heat is seasonal so SaaS stickiness is weak, and SMBs typically default to free HSE guidance or bundled EHS platforms — no evidence of strong willingness to pay a dedicated subscription.Workplace Heat Risk Assessment Tool — HSE Six-Factor Framework (EnviCourse) ↗IntegraRisk | UK Compliance & Risk Management Software ↗
Climate trend toward hotter UK summers is structural and law-firm/HSE activity (Gowling WLG 2026 article, Duncan Lewis 2025, BritSafe 2025, ongoing Commons Library briefing) shows compliance expectations tightening year-on-year — but heat-specific tooling is likely to be folded into broader EHS suites rather than stand alone.Too Hot to Work?

HSE's six-factor thermal-comfort framework is already publicly documented, weather and Met Office APIs plus SMS/email are commodity infrastructure, and LLM-generated risk assessments/PPE reminders are trivially prototyped — MVP is well within reach.Temperature in the workplace: Heat stress - HSE ↗
