Energy Price Cap October 2026: What the VAT Cut Really Means for Your Bill
Two changes land on your electricity bill on the same day — a price cap rise and a VAT cut to 0%. Here's the honest net effect, not just the headline either side wants you to focus on.
⚡ New price cap confirmed today. From 1 October 2026, the Ofgem cap rises to £1,723/year (+4%) — and electricity VAT drops from 5% to 0% the same day.
Quick answer: The energy price cap October 2026 figure is confirmed at £1,723 a year for a typical dual-fuel household on Direct Debit — up £60, or 4%, on the current £1,663. On the same day, VAT on domestic electricity falls from 5% to 0% until 31 March 2027. The two changes largely offset each other on electricity specifically, which is why electricity costs are rising by less than 1% even though the headline cap is up 4%. Gas gets no such relief and is doing almost all of the damage — up around 8.7%.
Two Changes, One Day
It's genuinely unusual for two separate, significant changes to hit your electricity bill on the exact same date, which is exactly what happened with the energy price cap October 2026 change and the VAT cut landing together.
First, the Ofgem price cap — the maximum a supplier can charge per unit of electricity and gas on a standard variable tariff — moved to its new quarterly level. Second, and separately, new Prime Minister Andy Burnham's government cut VAT on domestic electricity bills from 5% to 0%, announced on 21 July 2026 as one of the new administration's first cost-of-living measures, funded by cancelling the planned Digital ID programme.
These two changes moved independently of each other — and now they're both confirmed, we can see exactly how much they offset one another rather than guessing.
Energy Price Cap October 2026 — Confirmed
October–December 2026 cap (confirmed 26 August 2026)
Previous cap (July–September 2026): £1,663/year, 26.11p/kWh electricity (VAT-inclusive), 57.19p/day electricity standing charge, 7.33p/kWh gas.
Worth being precise about what the price cap actually controls: it sets the maximum rate per unit and the standing charge on standard variable and default tariffs — it does not cap your total bill. Use more energy, pay more, regardless of where the cap sits. If you're on a fixed-rate tariff, the cap doesn't directly apply to you at all, though fixed deals are often priced with the cap trajectory in mind.
⚠️ A trap worth avoiding: Ofgem's cap figures normally include 5% VAT, so July's rate of 26.11p/kWh is a VAT-inclusive number. From 1 October, electricity rates under the cap get restated without VAT. That means the new electricity unit rate can look lower than July's even where underlying wholesale costs have actually gone up — don't compare the two headline rates directly without accounting for the VAT change first.
The VAT Cut — What It Actually Covers
From 1 October 2026 to 31 March 2027, VAT on domestic electricity bills in England, Scotland and Wales drops from 5% to 0%. The government estimates this saves the average household around £45 over the period, though your actual saving depends entirely on how much electricity you use.
⚠️ Important details most headlines skip:
- This only applies to electricity — gas stays at 5% VAT, so dual-fuel bills only see the reduction on the electricity portion, which is exactly why gas is doing almost all of the damage in this quarter's rise
- It's temporary — the cut runs to 31 March 2027, after which any extension would need to be confirmed at the Autumn Budget on 28 October
- It applies to fixed-rate tariffs too, not just standard variable ones — suppliers are expected to pass the saving on regardless of tariff type
- Northern Ireland is excluded, since electricity VAT there is governed by different rules under the Windsor Framework — the NI Executive receives separate comparable funding instead
- The government hasn't confirmed any further financial support beyond this VAT cut — if more comes, it's more likely to land around the Autumn Budget or the January cap than this one
So Does This Actually Save You Money?
Now both figures are confirmed, the honest answer is genuinely nuanced rather than a single yes or no. For a typical dual-fuel household, the overall bill is rising by £60 a year — but that rise is almost entirely down to gas, which gets no VAT relief and is up around 8.7% on wholesale-driven cost increases largely linked to the ongoing Middle East conflict affecting gas markets.
Electricity specifically is a genuinely different story: the VAT cut has absorbed almost the entire underlying cost increase on that side, leaving the headline electricity rate up by less than 1% despite the overall cap rising 4%. So the practical reality: a gas-heavy household will feel this rise, while an all-electric household, or one leaning heavily on electric heating, solar, or a heat pump, will barely notice the change at all. That's a meaningfully different outcome depending on your setup, and it's exactly the kind of detail flat headline figures miss.
What This Means for Home Energy Upgrades
Every calculator on this site — solar, battery storage, heat pump running costs, EV charging, portable AC — uses the current Ofgem rate to estimate your savings. We're updating all of them to reflect the new confirmed rate.
Given gas is doing almost all of this quarter's damage while electricity stays nearly flat, the case for anything that moves your heating off gas — a heat pump in particular — has genuinely strengthened this quarter, not weakened. If you've been on the fence, this is a reasonable moment to actually run your own numbers rather than rely on last quarter's figures.
