Overview

• Forecasts cited by Bionic indicate daytime temperatures could fall to about 15C around 13 October, which many use as the signal to start heating.
• Energy Saving Trust advises against leaving systems on low all day, recommending schedules such as 30 minutes before waking, an hour before arriving home, and off 30 minutes before bed.
• Guidance highlights maintaining at least 18C indoors, avoiding any areas below 16C, with typical comfort settings between 18C and 21C.
• Lowering the thermostat by 1C can save about £90 a year, and draught‑proofing gaps around windows and doors can save up to roughly £80.
• With bills reported to rise at the start of October, boiler installers urge pre‑switch‑on checks including testing radiators, booking an annual service, cleaning vents and filters, and tightening up home insulation.
