As bills rise again this October, experts urge households to use online tools and explore dual fuel energy deals to avoid overpaying.
October Price Cap Brings Higher Bills
Ofgem has confirmed the October 2025 energy price cap will increase by 2%, taking the average annual dual fuel bill to £1,755. Despite falls in wholesale markets, UK households are still paying around £600 more each year than before the energy crisis began in 2021.
The steady rise has left more than one million households in arrears, according to research by the Resolution Foundation. StepChange, the debt charity, reports that two in five of its clients are already behind on energy bills, with average arrears of £2,300.
For many families, the challenge is no longer just seasonal spikes in winter bills — it’s about ongoing affordability all year round.
Why Energy Bill Calculators Are Becoming Essential
One of the most effective ways to check whether you’re paying too much is to use an energy bill calculator.
These tools allow households to:
- Enter their latest bill or annual usage.
- Compare the results against tariffs across the market.
- See instantly if switching supplier could cut costs.
Unlike simply looking at the headline rate of a tariff, calculators provide tailored results based on your personal usage. That means households with higher evening electricity demand, for example, can spot deals that better fit their profile.
For many families, the savings can be in the hundreds of pounds per year. With Ofgem’s cap changing every three months, regular use of calculators is becoming essential to avoid creeping costs.
The Growing Appeal of Dual Fuel Energy Deals
Alongside calculators, more households are opting for dual fuel energy deals. By combining gas and electricity with the same supplier, customers often benefit from:
- Simplified billing, with one account instead of two.
- Potential discounts for bundling services.
- Easier budgeting and fewer missed payments.
Dual fuel tariffs are not always the cheapest option, but in a volatile market they often provide stability and predictability. For families already stretched by higher council tax, rent, and food costs, this can be an important safeguard.
The Role of Ofgem’s Quarterly Cap
A major reason why calculators and dual fuel deals are gaining traction is the shift to Ofgem’s quarterly price cap updates. While the cap was introduced to protect households from sudden wholesale price spikes, it now passes market movements onto consumers more quickly.
That means a tariff that looks competitive in one quarter may suddenly become less favourable in the next. For households, this creates uncertainty and highlights the need for regular reviews of their energy plan.

Shay Ramani, CEO of Free Price Compare, explained:
“Families can’t control global energy markets, but they can control how they manage their energy at home. Using an energy bill calculator is the quickest way to see if you’re paying too much. In many cases, switching to a dual fuel tariff can simplify bills and lower costs, especially before the winter surge in demand.”
Ramani added:
“Government support schemes like the Warm Home Discount are helpful, but the most effective step households can take themselves is to stay proactive. Checking the market every few months makes a real difference in keeping costs under control.”
Practical Steps Before Winter
With millions of households already in arrears, taking action early is crucial. Experts suggest:
- Check your latest bill — note down both usage and total cost.
- Run details through an energy bill calculator — see how your current deal compares to market options.
- Explore dual fuel tariffs — weigh the convenience and possible savings of bundling gas and electricity.
- Switch if a better deal exists — even modest savings of £150–£200 per year can help reduce arrears and ease household pressure.
A Clear Way Forward
Although global energy markets remain volatile, UK households are not powerless. By using energy bill calculators and considering dual fuel energy deals, families can take practical steps to cut costs, build resilience, and stay ahead of rising bills.
