The Office for National Statistics reported inflation at 2.8% for September, down from 3.2% in August, the lowest rate since April 2021. The main driver: a smaller rise in household energy bills, thanks to Ofgem’s price cap limiting the typical annual dual-fuel cost to £1,923. That is still £400 more than the pre-crisis average, but it is not the 40% jump many feared.
As reported by The Guardian, the data masks wide regional variation: households in Northern Ireland and parts of Scotland pay more due to higher standing charges, while those on standard variable tariffs in the South East benefit from lower per-kWh rates.
What the price cap actually covers, and what it misses
Ofgem’s cap applies to default tariff customers, about 85% of households. It sets a maximum unit rate for electricity (currently 27.35p/kWh) and gas (6.89p/kWh), plus a daily standing charge of 53p for electricity and 30p for gas. For a typical 3-bed semi using 12,000 kWh of gas and 2,900 kWh of electricity, the annual bill lands at £1,923.
But the cap does not protect prepayment meter users, who pay about 10% more on average, nor those on Economy 7 or other time-of-use tariffs. It also does not cover households with electric heating or heat pumps, where electricity consumption can be double the typical figure. For those homes, the effective annual cost can exceed £3,000.
The catch is that inflation falling does not mean bills are falling, they are just rising more slowly. The Bank of England still expects energy costs to stay elevated through 2025, with wholesale gas prices 60% above their pre-crisis average.
What this means for your home and EPC rating
For UK homeowners, the key takeaway is that energy efficiency is no longer a nice-to-have, it is a direct hedge against future price shocks. The Energy Saving Trust estimates that a typical semi-detached home can save £200 a year by topping up loft insulation to 270mm and another £150 by draught-proofing windows and doors. Combined with a modern condensing boiler or a heat pump, the savings can push past £500 a year.
These upgrades also improve your Energy Performance Certificate rating, which matters when selling. A home moving from EPC band D to C adds roughly 5% to its sale value, according to Nationwide Building Society data. Given that the average UK home sits at band D, the financial case for insulation, solar panels, or a heat pump is stronger than ever.
The Great British Insulation Scheme closed on 31 March 2026. It funded insulation measures only and never covered windows or glazing. Applications for the latter remain open until March 2026.
Three steps to take this month
First, check your EPC, it is free via gov.uk and shows exactly where your home leaks heat. Second, compare your current tariff against the price cap: if you are on a fixed deal ending soon, you may save £100–£150 by switching to a capped variable tariff now. Third, book an insulation survey; many local councils offer subsidised visits through the Energy Company Obligation scheme.
Households with solar panels and battery storage are already seeing the biggest benefit. With the price cap keeping export tariffs at 15p/kWh for new installations, a typical 4 kW system can generate £500–£700 in savings and payments per year, enough to pay back the installation cost in under a decade.
The inflation number is good news in the sense that the worst of the price spike is behind us. But the underlying pressure on household budgets remains. For homeowners, the smartest move is to reduce consumption at source, through fabric-first upgrades, renewable generation, and better heating controls. The price cap will not stay low forever.
Frequently Asked Questions
Not necessarily. Ofgem reviews the cap every three months based on wholesale prices. If gas demand rises this winter, the cap could increase by £100–£200 in January 2025, pushing inflation back up. The inflation figure is a snapshot, not a trend.
Draught-proofing windows and doors costs under £100 in materials and can save £150 a year. Loft insulation top-up (to 270mm) costs £300–£600 installed and can save £200 a year. Both typically pay back within two to three years and lift your EPC by one or two bands.
