Next update: when Ofgem reprints the next quarterly cap or MSM fixed ladders move materially.
By: Switch Editorial Team, Switch Squid Ltd
As of 24 September 2026, the clean October switch-season rule for households is: Ofgem’s dual-fuel Direct Debit price cap is £1,723 a year from 1 October to 31 December 2026 (about 4% above the Jul–Sep £1,663 level) — so compare live fixed dual-fuel quotes now, and only lock a fixed if the all-in Year-1 cash clearly beats your expected SVT bill after standing charges, regional rates and exit fees. Primary Compare buttons use MoneySuperMarket’s Awin home-energy journey (campaign 911601 / soft mid 22713) — never SwitchSquid’s own /energy/ hub as the money button, and never business-energy CTAs.

Ofgem £1,723 — what the number is (and is not)
Ofgem publishes the Oct–Dec 2026 dual-fuel Direct Debit typical bill at £1,723 for a medium TDCV household (about 2,500 kWh electricity / 9,500 kWh gas). Average Direct Debit unit rates cited by Ofgem for the period include roughly 26.32 p/kWh electricity with a 54.83 p/day standing charge, and 7.97 p/kWh gas with a 29.68 p/day standing charge (gas includes 5% VAT; electricity VAT is 0% from 1 October 2026 to 31 March 2027 under the published policy window). Your bill is not the national average — region, meter type, payment method and real kWh move the cash.
We do not invent supplier-specific fixed £/year figures (Fuse / Outfox / E.ON or anyone else) in this guide. Those tiles move daily on comparison engines. The method below is how you find whether a named fixed beats the cap sketch for your usage.
Fixed vs SVT decision table (October 2026)
| Question | Stay on SVT (cap) | Lock a fixed via MSM |
|---|---|---|
| Headline national sketch | £1,723 dual-fuel DD typical (Ofgem Oct–Dec 2026) | Named fixed quote for your kWh |
| Price moves | Every quarterly Ofgem announcement | Unit/standing fixed for the term (read rise clauses) |
| Best when | You expect wholesale to fall and can re-compare | A live fixed undercuts your expected SVT after fees |
| Risk | Winter bill shock if rates rise again | Exit fees if you leave early; overpaying if SVT falls |
| Action | Re-compare each Ofgem update | Take the fixed only if Year-1 cash wins |

How to hunt the cheapest fixed without inventing a leaderboard
1) Pull 12 months of kWh (or annualise the last bill). 2) Sketch an SVT bill with Ofgem’s published averages only as a national starting point — replace with your region’s rates from Ofgem’s area tables or your supplier letter. 3) Run at least three fixed dual-fuel quotes on MSM for the same usage and payment method. 4) Add exit fees if you are leaving a fixed early. 5) Check single-fuel electricity-only and gas-only fixeds too — dual-fuel is not automatically cheaper once two standing charges stack. 6) Fix only if the all-in Year-1 cash wins.
Supplier brands you will often see in October comparison results include larger SVT names and challenger fixeds. Treat every £/year tile as ephemeral. If a blog quotes “Fuse £1,489” or “Outfox £1,516” without a live MSM screenshot and timestamp, ignore it — we will not reprint unverified pounds here.
Direct Debit, PPM, Economy 7 — do not mix the maths
The £1,723 sketch is Direct Debit dual-fuel typical. Prepayment, standard credit and Economy 7 have different Ofgem presentational levels. If you are on E7, compare multi-rate fixeds and watch peak/off-peak share — a cheap overnight rate is useless if your heat pump or EV charges at the wrong clock.
Green, smart TOU and partial fixes
Some households only need to fix gas while electricity rides a smart time-of-use tariff — or the reverse. Price both. REGOs and “green” labels do not automatically mean lower cash; decide whether you are buying pounds or attributes.
Standing charges, regions and why “£200 under the cap” can still lose
Standing charges are the quiet killer in October comparisons. Two single-fuel fixeds can look cheap on unit rates and still lose to one dual-fuel bundle once daily standing stacks. Regional distribution costs mean a London sketch is not a Glasgow bill. Always replace the national £1,723 figure with your region’s Ofgem table or the rates on your latest statement before you celebrate a “saving”.
Exit fees on an existing fixed deserve the same honesty. A £75 exit fee that unlocks a genuine £180 Year-1 win is rational; a £40 paper saving that ignores the fee is marketing. If you are within three months of the end date, ask about cooling-off and renewal notices before you panic-switch.
What “cheapest” should mean in a SwitchSquid guide
Cheapest is not the lowest tile on a screenshot from Tuesday. Cheapest is the lowest all-in cash for your meter, payment method and risk tolerance after fees. That is why this guide refuses to crown Fuse, Outfox, E.ON Next or anyone else with a frozen £/year number. MSM’s live engine is the execution surface; Ofgem is the SVT benchmark; your kWh file is the tie-breaker.
If a friend forwards a viral “£1,489 fixed” graphic without a postcode, usage assumption, or timestamp, treat it as entertainment. Re-run MSM with your data. If the same brand still wins, take it through the Awin journey so the checkout terms match the tile you think you bought.
Warm homes without magical thinking
Tariff choice does not replace draught-proofing, TRVs, or a serviced boiler. October is also when heating comes on properly — so a smart thermostat schedule and bleeding radiators can move cash as much as a 0.2 p/kWh unit difference. Do both: fix the tariff if the maths wins, and stop heating the street through the letterbox.

FAQ
What is the cheapest fixed energy deal October 2026?
The honest answer is: whichever live MSM fixed undercuts your expected SVT after fees for your kWh today. We will not invent a crown.
Is the Ofgem cap £1,723?
Yes for the Oct–Dec 2026 dual-fuel Direct Debit typical bill published by Ofgem — not a personal guarantee.
Should I fix before 1 October?
Compare now. Fix only if the quote wins. Waiting for the next Ofgem announcement is rational if no fixed beats your sketch.
Why MoneySuperMarket?
Home energy CTAs must be MSM Awin (aff 911601 / soft mid 22713). We never send residential switchers to the business-energy form.
Do you sell Nest energy SKUs?
No. Residential cash decisions go through MSM. Do not invent Nest domestic kWh products on this CTA.
What about Fuse / Outfox / E.ON fixeds?
Soft-check them on MSM. We refuse to print unverified £/year figures that will be wrong by lunchtime.
Does the VAT cut change the maths?
Ofgem’s published Oct–Dec presentation already reflects the electricity VAT policy window. Still use your bill + MSM quotes, not a napkin average alone.
