The October price cap will add £63 to the average household bill, pushing the typical annual cost to £1,923. That is the third increase this year, and with winter approaching, every pound matters. Into this landscape steps E.ON Next with a relaunched tariff that promises 100% renewable electricity and a £131 saving against the cap.
The E.ON Next Gust tariff is not a fixed deal, it is a variable rate tied to the price cap, but with a discount applied. The company says the typical dual-fuel customer on standard usage (2,900 kWh electricity, 12,000 kWh gas) will pay £1,792 a year, compared to the cap’s £1,923. That is £131 less, or about 7% below the benchmark.
Who qualifies, and who doesn’t
To get the Gust tariff, you need a smart meter. That is non-negotiable. E.ON Next says the tariff is designed for customers who want to track their usage in real time and shift consumption to cheaper periods, though the tariff does not have time-of-use rates. The renewable electricity is backed by Renewable Energy Guarantees of Origin (REGO) certificates, so you can claim your power is 100% green. Gas, however, is not included in the renewable promise. If you are on heat pumps or have solar panels, the green electricity match adds genuine environmental value, but it does not lower your gas bill.
What it costs a typical 3-bed semi
Ofgem’s typical domestic consumption values (TDCVs) are the benchmark here. For a 3-bed semi using 2,900 kWh of electricity and 12,000 kWh of gas, the Gust tariff undercuts the cap by about £131. But that is the headline figure. The actual saving depends on your region: standing charges vary, and the Gust discount is applied to the unit rate only. In London, where standing charges are lower, the saving might be slightly less; in the North West, slightly more. Energy Saving Trust notes that variable tariffs can change with 30 days’ notice, so the £131 figure is not locked in. If wholesale prices spike, the discount may shrink or disappear.
The catch, and what it misses
But here is the rub: the Gust tariff is not fixed. The price cap is already rising, and if Ofgem raises it again in January (as analysts expect), the Gust tariff will rise in step, minus the discount. Compare that to a fixed deal: you lock in a rate for 12 or 18 months, protecting yourself from further increases. Fixed tariffs are currently around £1,850–£1,900 for typical usage, according to comparison sites. So the Gust tariff is cheaper than the cap, but not necessarily cheaper than a competitive fix. The other missing piece: the £131 saving assumes you stay on the tariff for a full year. If you switch away early, there is no exit fee, but you lose the discount.
What this means for your EPC and home upgrades
For homeowners investing in eco upgrades, the Gust tariff is a useful complement. If you install a heat pump or solar panels, pairing them with a 100% renewable electricity tariff reduces your carbon footprint further. But the tariff itself does not improve your EPC rating, that depends on fabric efficiency, heating system, and insulation. The Energy Company Obligation (ECO4) scheme can help with insulation and boiler upgrades, but the Gust tariff is a supply-side choice, not a retrofit tool. The real action for EPC improvement remains: loft insulation (costs £300–£500, saves £200–£300 a year), cavity wall insulation (£400–£700, saves £200–£400), and double glazing (£3,000–£7,000, saves £100–£200).
How to decide, and what to do next
If you have a smart meter and want to support renewable generation, the Gust tariff is a decent option, especially if you are currently on the standard variable tariff (which almost everyone is after the energy crisis). But do not assume it is the cheapest. Use a comparison site to check fixed deals first. If you find a fix below £1,800 a year, that is likely better value. If not, the Gust tariff offers a modest saving with a green badge. Households on standard variable tariffs can apply through E.ON Next’s website from today. Eligibility is open to new and existing customers. The tariff has no fixed end date, but the discount is guaranteed only until E.ON Next changes it. Act before the next price cap announcement in November if you want to lock in the current discount.
Frequently Asked Questions
It depends on the fixed deals available. Currently, the Gust tariff is about £1,792 a year for typical usage, while fixed deals range from £1,800 to £1,900. Use a comparison site to check. If you find a fix below £1,800, that is likely better value and provides price certainty.
Indirectly, yes. The electricity is 100% renewable, which reduces the carbon footprint of running a heat pump. But the unit rate is still tied to the price cap, so you won't get a cheaper electricity rate than the market average. For lower running costs, consider a heat pump-specific tariff or time-of-use tariff if available.
