Electricity VAT Cut October 2026: Will Your Bill Actually Go Down?

If you use more or less electricity than average, your actual saving will be different. There's also no confirmed end date for the 0% rate — nothing on the official announcement states how long it will run, so don't assume it's permanent or that it stops on any particular date.

Northern Ireland note: the change doesn't apply directly in NI, because EU VAT rules still cover goods including electricity there under the terms of the UK's EU exit. Instead, the NI Executive receives comparable funding to support households with the cost of living. If you're in NI, this particular VAT change isn't the mechanism helping your bill — a different funding route is.

Rather than guess at a headline number that keeps shifting, the more useful move is to check your own current unit rate on your bill or supplier's app, and revisit the sums once the new cap lands.

That's exactly what our free washing machine cost calculator does. Plug in your machine's wattage (or model, if you know it), your cycle length and your own unit rate, and it works out a genuine cost per wash for your household — not a national average that may not apply to you. Try the washing machine cost calculator and see what a week of back-to-school laundry is really costing you.

Once Ofgem's new cap is confirmed, it's worth re-running the numbers with your updated unit rate — and checking other appliances too. Our energy tools hub covers heaters, kettles, fridge freezers and dishwashers, or browse all calculators to see the full set.

In the meantime, a few habits reliably cut what each load costs:

• Wash on 30°C, not 40°C or higher, where the load allows it. Most of a wash's electricity goes on heating the water.
• Wait for a full load rather than running half-empty cycles — you pay roughly the same electricity for a half load as a full one.
• Use the eco setting if your machine has one; it typically runs longer but uses less power overall.
• Check your machine's actual running cost against your own tariff, rather than guessing.

Q: How much will I actually save? A: The government estimates around £45 a year off the typical price cap, but that's based on average usage. Your real saving depends on how much electricity you use — the calculator can help you see the difference your own consumption makes once you know your new unit rate.

Q: When will I know the real October 2026 price cap figure? A: Ofgem is due to publish the October–December 2026 cap by 26 August 2026. Until then, any specific total you see quoted is either an old figure or an independent forecast, not a confirmed number.

Q: Does this apply in Northern Ireland? A: Not directly. EU VAT rules still apply to goods including electricity in NI, so the 0% rate doesn't take effect there in the same way. The NI Executive instead receives comparable funding to help households with the cost of living.

Q: Is the VAT cut permanent? A: It hasn't been confirmed either way. The government's announcement doesn't state an end date, so it's safest to treat it as ongoing until told otherwise rather than assume it's permanent or temporary.
