As winter descends and temperatures plummet, many households are grappling with the impact of rising energy costs. With Ofgem’s energy price cap increasing to £1,758 per year as of 1 January, families are feeling the pinch, especially amid ongoing inflation and soaring food prices. However, heating experts suggest that many of us could be unwittingly inflating our bills through common heating mistakes. Fortunately, a few straightforward adjustments can lead to significant savings.

Common Mistakes That Cost You Dearly

Heating specialists at UK Radiators warn that simple oversights can add an astonishing £400 to £600 annually to energy bills. Issues like blocked radiators and failure to bleed systems can impact efficiency, leading to increased costs. Rob Jones, a heating expert, explains, “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.”

He advises homeowners to take proactive measures now by bleeding radiators, ensuring they are unobstructed, and running heating systems for a short period to identify any lurking issues. Such preventative steps can save both money and stress when the winter chill sets in.

Optimising Your Boiler Settings

One of the most effective ways to reduce heating bills lies in adjusting your boiler’s flow temperature. Many people leave their boilers set at the default temperature of 80°C, which can lead to unnecessary gas consumption. David Holmes, CEO of WhatPrice.co.uk, recommends setting the flow temperature between 55 and 60°C. “This allows the boiler to operate in condensing mode, which minimises wasted energy,” he shares. This simple adjustment not only conserves energy but also reduces wear and tear on the boiler, potentially extending its lifespan.

For those unsure about how to adjust the settings, consulting a Gas Safe registered engineer is advisable to ensure safety.

The Thermostat Dilemma

Incorrect thermostat usage is another common culprit for inflated energy bills. Many households mistakenly believe that turning the thermostat up high will heat their homes more quickly, but this approach often backfires. Ryan Willdig, a heating specialist at Heatforce, clarifies, “Each degree above 19–20°C can add around 10 per cent to annual heating costs.” Instead, he suggests maintaining a stable temperature to avoid unnecessary expenses.

Additionally, poorly insulated homes exacerbate heat loss. While comprehensive insulation upgrades can be costly, affordable solutions like draught excluders and radiator reflectors can make a noticeable difference in maintaining warmth without breaking the bank.

Embracing Smart Technology for Savings

Smart thermostats have emerged as a practical solution for managing heating efficiently. Devices from brands like Hive and Tado can help households tailor their heating schedules to their daily routines. Instead of keeping the heating on constantly, users can programme their devices to warm spaces just before they are in use and lower temperatures when they’re not at home.

Gav Murray, home heating director at Hive, emphasises the financial benefits of eco-tech devices. “By allowing people to easily schedule their heating, adjust settings remotely, or receive reminders when the heating has been left on, smart thermostats ensure you’re only using energy when you really need it. That means less wasted heat, lower energy consumption, and savings on bills—without compromising comfort.”

Why it Matters

As energy prices continue to rise, it’s vital for households to take control of their heating habits. Small changes can lead to significant savings, alleviating some of the financial strain many families are experiencing this winter. By being proactive and making simple adjustments to heating systems and behaviour, households can not only save money but also contribute to more sustainable energy consumption. This winter, let’s prioritise comfort and affordability, ensuring that a warm home doesn’t come at an astronomical cost.
