Black Friday 2026: heaters, heated throws and dehumidifiers
Black Friday is Friday 27 November and Cyber Monday is 30 November. The heaters, throws and dehumidifiers worth buying, and how to tell a real deal.
How to spot a genuine heater deal
Check the 30-day price
A real deal is below the lowest price of the last 30 days, not just below the RRP.
Thermostat and timer
They are what cuts the running cost, which matters more than a few pounds off.
Right size
About 100 W per m² for a radiator. A bigger heater just costs more per hour.
Safety
Tip-over and overheat protection; IP24 for bathrooms.
