HomeCool Audit
A one-time home-heat audit that takes a photo of your flat, house, or workplace and tells you exactly how to keep it cool — which windows to open, what to put on the roof, where to put a fan, and how to spot when your home is dangerously hot.
UK renters and homeowners in older housing stock who lack air conditioning
- Photo-based heat-loss and heat-gain assessment using simple room shots
- Tailored action plan ranked by cost (free, under £20, under £100) and effectiveness
- Shopping list with UK-specific products and price comparisons
- Reminders to re-open windows overnight when temperatures drop
The 2026 heatwave is the fourth of the year and warnings are explicit about high-rise flats and elderly residents; UK housing is largely un-air-conditioned, leaving most people improvising.
UK AC installation requests up 320%, 3M+ English homes reported uncomfortably hot in 2024, AC households doubled to ~4M, and UKHSA recorded 1,504 heat deaths in summer 2025 rising to ~2,900 in 2026 heatwaves — exceptional real-world urgency.UK Air Conditioning Boom: 3 Million English Homes Overheat ↗New UKHSA data shows 1,504 heat-related deaths during summer of 2025 ↗Air conditioning installation requests up in the UK by 320% ↗
Direct consumer 'photo-to-cooling-plan' products are absent; ThermaScan Pro, Inspekt AI and thermal-EPC tools target contractors/B2B, and Clean Energy Project Builder's AI Home Scanner is energy/heat-pump focused rather than cooling-specific.Thermal Imaging Energy Audit App | ThermaScan Pro ↗Building Thermal Imaging: Detect Hidden Issues | Inspekt AI ↗AI Home Scanner | Clean Energy Project Builder ↗
No direct WTP data for £5-20 cooling audits; UK willingness-to-pay studies (Nesta, Which?, Citizens Advice) centre on heat pumps and insulation (£2k-12k range), leaving one-off photo audits unproven and likely competing with free NHS/UKHSA and Which? advice pages.Estimating the willingness to pay for a heat pump | Nesta ↗Low Carbon Home Upgrades Data Insights Report - Citizens Advice ↗
Structural, multi-decade shift: UK AC penetration expected to rise from ~3% to ~30% by 2050, government policy now actively supports cooling, and Reading/UKHSA evidence shows widening heat-mortality gap — summers will keep getting hotter for the target demographic.Assessing the future heating and cooling needs of the UK housing stock ↗The most at risk from heat have the least air con ↗
A 'photo-of-flat' cooling audit is buildable as an MVP using CV + rules-based advice (window cross-ventilation, shading, fan placement), but genuine thermal diagnostics normally require IR imagery, so accuracy from a single RGB photo is limited without hardware.Thermal Imaging for Energy Audits: Assessing Energy Efficiency in Buildings ↗How Many UK Homes Have AC?
