Survive the British Summer

Honest, plain-English cooling guides for UK homes. We cut through the marketing noise to help you choose what actually works for your bedroom, flat, or awkward windows.

Full guides launching soon. Check back here in a few days.

Why UK Homes Get So Hot

British houses are designed for heat retention. Cavity wall insulation, double glazing, and heavy bricks trap heat like ovens during summer heatwaves. We explain the thermodynamics of how to flush heat out at night using simple, passive airflow tricks.

The Window Venting Challenge

Typical portable air conditioners include venting kits designed for sliding sash windows. But most modern UK homes have outward-opening casement windows. We guide you on fabric zip seals, custom panels, and renter-friendly window kits that protect your paintwork.

Fans vs Coolers vs Active AC

Do not waste money on evaporative air coolers. They raise humidity and make sticky UK summer nights feel even more stuffy. Learn the differences in power draw, decibel levels, and cooling capacity so you purchase the right setup the first time.

Portable AC Running Cost Estimator

Estimate the electrical running cost based on the standard July 2026 Ofgem price cap average of 26p/kWh.

Fans are typically 50W. Portable ACs range between 900W and 1400W.

Estimated Cost Per Hour £0.21
Estimated Cost Per Day £1.25
Estimated Cost Per Month (20 Days) £24.96

Calculations automatically apply an 80% duty cycle factor for high-wattage air conditioners (above 500W). This accounts for compressor cycling on and off. Low-wattage fans run at 100% duty cycle.
