Slash Energy Bills by £100 with One Simple Change
Share
As the cost-of-living crisis continues to squeeze household budgets, energy experts are urging Britons to take action now to minimise their energy bills ahead of the colder months.
From April 2025, the energy price cap rose by 6.4%, increasing the average annual bill for a typical dual-fuel household paying by direct debit to £1,849 — up from £1,738. A further adjustment to the cap is expected in July.
In light of this, Gordon Wallis, at heating oil supplier Your NRG, has shared a range of practical, low-cost tips to help families reduce their energy use and avoid unnecessary costs.
“Energy prices may be rising again, but households still have tools to take back control,” said Mr Wallis.
“Even small changes can make a noticeable difference over the course of a year.”
Among the most effective actions is turning your thermostat down by just 1°C — a move Mr Wallis says can save the average household over £100 annually without making a significant difference to comfort.
“Lowering the thermostat from 20°C to 19°C is barely noticeable day-to-day, but it could shave over £100 off your energy bill,” he explained. “It’s a free change that doesn’t impact quality of life but really adds up over time.”
Mr Wallis also recommends using thermostatic radiator valves to better control the heating in less-used rooms, with potential savings of around £75 per year, according to Energy Saving Trust figures.
For those prepared to invest a small amount, a hot water cylinder jacket — costing around £15 — can quickly reduce heat loss in older systems. Meanwhile, draught-proofing doors and windows, or hanging heavyweight curtains, can stop warmth from escaping unnecessarily.
“Simple fixes like these can stop your hard-earned money from literally slipping through the cracks,” Mr Wallis added.
Longer-term savings may require more substantial upgrades. Mr Wallis suggests homeowners consider the age and efficiency of their boiler, which could be costing them hundreds of pounds a year if outdated.
“Older boilers can be as little as 60% efficient, meaning 40% of your energy is wasted,” he said. “Replacing it with a modern A-rated model could save up to £540 annually and reduce long-term strain on the system.”
Smart meters are another effective tool, allowing households to monitor energy use in real time and avoid overpayments based on inaccurate estimates.
“Smart meters help reduce billing errors and encourage smarter usage,” Mr Wallis said. “When you can see how much energy you’re using — and what it’s costing — you naturally become more conscious of waste.”
With energy bills climbing and another cap review on the horizon, experts are encouraging households to prepare now by making cost-saving adjustments that can deliver meaningful results.
“There’s no need to wait for winter,” Mr Wallis added. “These actions can benefit you all year round — and protect you from future price hikes.”
