With colder weather approaching, heating experts are warning UK homeowners that simple radiator neglect could add hundreds to annual energy bills. Failing to perform basic checks before switching on the heating can lead to costs of up to £600 a year in higher energy use and repairs.
Rob Jones, heating specialist at UK Radiators, said: “The average household could be losing between £400 and £600 a year just by ignoring their radiators. Most people only notice problems when they switch the heating on in November and suddenly half the house is cold. By then, it’s often too late — small fixes have become expensive call-outs.”
Key mistakes include not bleeding radiators, which can reduce efficiency by 15% and cost £70–£100; radiator sludge buildup, forcing boilers to overwork and costing £200–£300 (or over £400 for breakdowns); and obstructing radiators with furniture, costing £60–£80. Drying clothes on radiators reduces heat output by 20%, adding £100–£120, while heating unused rooms without thermostatic radiator valves can waste £50–£150. Neglecting small leaks may lead to repairs costing £150–£500.
Experts recommend bleeding radiators, clearing space around them, and running the heating for 20 minutes to identify issues early. Using radiator reflectors can save £30–£50 annually. Addressing these simple checks now can prevent costly problems later.
