Switch energy after the October 2026 price cap: what £1,723 means for your bill

Last updated: Tuesday 29 September 2026 (Europe/London).
Next update: when Ofgem publishes the January–March 2027 price-cap decision (due 25 November 2026) or typical-use sketches change.

As of 29 September 2026, Ofgem’s Oct–Dec dual-fuel Direct Debit typical bill is £1,723 — and the practical question for most households is whether to switch now that the new cap period is days away, not whether the headline figure alone “is expensive”. £1,723 is a typical-use sketch (about 2,500 kWh electricity and 9,500 kWh gas), not your personal bill.

What changed on 1 October 2026

From 1 October to 31 December 2026, default (standard variable) tariffs are capped at higher unit rates and standing charges than the July–September period. Ofgem’s national Direct Debit averages for that window are roughly 26.32p/kWh electricity with 54.83p/day standing, and 7.97p/kWh gas with 29.68p/day standing. Electricity averages for Oct–Mar reflect 0% VAT on electricity in the published period; gas averages still include 5% VAT.

If you are already on a competitive fixed deal, the new cap does not rewrite your contract. If you are on a default tariff, the new pence apply from 1 October unless you complete a switch onto a different product first. That is the switch-season lever this guide is about.

£1,723 ÷ 12 is about £143.50 a month for the typical sketch. Low users sit under it; large homes and electric heating sit above it even before winter peaks. Always export 12 months of kWh (or your best annual estimate) before you trust any “£X saving” tile.

Should you switch in the first week of October?

Three practical cases:

1. On a default tariff, no exit fee: Run a like-for-like MoneySuperMarket quote with the same postcode and usage. If a fixed or other live product undercuts your expected Year-1 SVT cost after any signup incentives end, switching early in the cap period can lock winter rates before cold weather usage spikes.
2. Inside a fixed with an exit fee: Do the exit-fee maths first. A tempting tile that saves £80 Year-1 but costs £120 to leave is not a win. Our separate exit-fees October guide covers that arithmetic in more depth — this URL stays on post-cap action for people who can move.
3. Already on a sharp fixed: You may still compare once for peace of mind, but do not churn for a few pounds if the new deal’s out-of-contract or post-benefit price looks weak.

Fit summary

Good for: households on default tariffs who want a clear October switch checklist under the £1,723 sketch.
Consider alternatives: Economy 7, heat-of-use and EV tariffs need multi-rate comparisons, not only dual-fuel Direct Debit tiles.
Not for: business meters — use our separate business-energy form path, never the residential Compare buttons here.

Important conditions

• £1,723 is Ofgem’s typical-use Direct Debit sketch, not a personal guarantee.
• Standing charges and unit rates vary by region and payment method (Direct Debit, standard credit, prepay).
• Fixed deals sit outside the cap — read term length, exit fees and what happens when the fix ends.
• Warm Home Discount eligibility is separate from the tariff quote; confirm with your supplier if you rely on the rebate.
• Prepay and smart-meter journeys can show different product sets — stick to payment methods you can actually use.
• Northern Ireland has a different retail market; this guide is for Great Britain.

Switching steps (twenty minutes)

1) Note whether you are on a default tariff or a fixed, and any exit fee.
2) Export 12 months of electricity and gas kWh (or estimate carefully).
3) Open MoneySuperMarket with the same postcode, meter type and payment method.
4) Rank by estimated annual cost; open standing + unit rates on shortlisted labels.
5) Check cool-off and start dates so you are not billed twice for the same week.
6) Only switch if Year-1 all-in wins after exit fees and after any temporary credits end.

Final decision card

Default tariff, no exit pain, and a live deal undercuts your Year-1 sketch → switch.
Deep inside a fixed with a steep exit fee → stay unless savings clearly clear the fee.
Already on a strong fixed → compare once, then leave well alone until the next renewal window.

Worked shapes (illustrative, not quotes)

Flat on Direct Debit SVT, ~1,800 kWh elec / 8,000 kWh gas: Your annual cash will sit under £1,723. Still compare — a low standing-charge product can matter more than chasing the headline unit rate.

Family home near TDCV: Treat £1,723 as a rough yardstick. If a 12-month fix quotes £1,580 all-in at your kWh with a modest exit fee, October is a sensible switch week.

Large electric heating load: Dual-fuel Direct Debit tiles may understate your electricity share. Prefer comparisons that accept your real split, and consider multi-rate products if you can shift load overnight.

Payment method and meter quirks after the cap

Direct Debit, standard credit and prepay sit on different capped averages. A household that “looks cheap” on Direct Debit can look different on prepay even before supplier margins. If you are changing payment method at the same time as supplier, model both changes — do not assume the £1,723 sketch still applies after you move to a key meter.

Smart meters help accurate switching, but a delayed install should not freeze you on a poor default tariff forever. Use the best annual usage you have, keep bill PDFs, and update the quote when the smart meter starts reporting properly.

What the January announcement changes (and does not)

Ofgem is due to set January–March 2027 cap levels on 25 November 2026. That date matters for people who deliberately stay on a default tariff through autumn. It does not automatically cancel a fixed you take in early October. If you fix in October, you are buying rate certainty through your contract term; you are not “betting against” November’s press release.

Supplier forecasts floating around £1,900+ for early 2027 are not Ofgem decisions. Treat them as context, not as a guaranteed saving figure inside a comparison tile.

How to read a comparison tile after 1 October

Comparison results often lead with “£X saving versus the price cap”. That saving is only meaningful if the baseline matches your payment method, region and usage. A tile that assumes 2,500 / 9,500 kWh will flatter a small flat and understate a large house. Open the tariff breakdown every time: unit rates, standing charges, exit fees, and whether any credit is a one-off goodwill payment that vanishes after month three.

Also watch dual-fuel versus single-fuel packaging. If you heat with a heat pump or Economy 7, a dual-fuel Direct Debit tile can hide a poor electricity unit rate behind a soft gas figure. Ask for the electricity-only view when gas is not your main lever.

Paper bills still matter. Photograph the tariff name, the MPAN/MPRN and the payment method before you switch. When the welcome pack arrives, check that the rates you accepted are the rates on the schedule. Cooling-off exists for a reason — use it if the paperwork does not match the screen.

Renters, landlords and who can authorise the switch

If the energy account is in your name, you can usually switch even in a rented property, subject to the tenancy and any landlord clause about preferred suppliers. If the landlord’s name is on the bill, you cannot quietly move the supply. Shared houses should agree who the bill-payer is before anyone clicks Compare, or you risk a half-switched account and a messy deposit deduction later.

Students moving in October often inherit a default tariff from the previous tenants. Treat that as a switch trigger the same week you set up council tax or Wi-Fi. Waiting until January “when it is colder” usually means paying the new cap rates through the expensive months first.

FAQ

What is the Ofgem price cap in October 2026?
For 1 October–31 December 2026 the typical dual-fuel Direct Debit bill sketch is £1,723 a year. Your bill depends on usage, region and payment method.

No. The cap limits default (standard variable) unit rates and standing charges. Fixed deals sit outside it until they end.

Should I switch energy as soon as the October cap starts?
Switch if a live deal beats your expected Year-1 default cost after exit fees. If you cannot leave cheaply, wait or renegotiate rather than paying to churn.

Is £1,723 what I will pay?
Only if your usage matches Ofgem’s typical-use assumptions and you are on a capped default tariff paid by Direct Debit. Most homes differ.

Ofgem is due to announce January–March 2027 levels on 25 November 2026.

Do standing charges rise in October 2026?
National Direct Debit averages for the Oct–Dec window include electricity standing around 54.83p/day and gas around 29.68p/day — check your region’s table on Ofgem.
