Energy Saving FAQ
Everything you need to know about cutting home energy use in the UK in 2026.
The most effective steps are typically improving loft and wall insulation, switching to a smart thermostat with lower heating schedules, replacing remaining bulbs with LEDs, washing clothes at lower temperatures, and turning appliances off standby rather than leaving them idle.
LED bulbs typically use around 75-80% less energy than traditional incandescent bulbs and last significantly longer, making lighting one of the easiest and quickest home energy upgrades.
Yes. Turning your thermostat down by just 1 degree Celsius can reduce heating energy use by around 8-10% in a typical UK home, since heating usually accounts for the largest share of household energy consumption.
Appliances left on standby can account for several percent of a typical household’s total electricity use. Turning devices off at the wall rather than leaving them on standby is a simple way to reduce this waste.
Yes. Up to a quarter of heat loss in an uninsulated home escapes through the roof, so adding or topping up loft insulation is one of the most effective long-term ways to reduce heating energy use in a UK home.
