Should I fix my energy deal or stay on the price cap?

Last updated: Sunday 27 September 2026 (Europe/London)

27 September 2026 refresh: The current Oct–Dec 2026 typical dual-fuel Direct Debit figure is £1,723. July–September was £1,663 (new TDCV) / £1,862 (old-TDCV presentational) — historical only. Compare fixed quotes on the energy hub.

Yes, fix your energy deal if a supplier's fixed rate beats the current price cap in your region and you plan to stay at your address for the whole contract term. Ofgem set the October–December 2026 energy price cap at £1,723 a year for a typical Direct Debit dual-fuel household (new TDCV 2,500 / 9,500 kWh) — about 4% above July–September’s new-TDCV £1,663. The July move itself was to £1,663 (new) / £1,862 (old presentational), not to £1,723. A fix energy deal locks your unit rate and standing charge for the length of the contract, so your bill stays flat even if Ofgem changes the cap again in January 2027.

Why Did Energy Prices Rise in July 2026?

Ofgem reviews the price cap four times a year: January, April, July, and October. The July 2026 review raised the cap by 13%, from £1,641 to £1,862 under the old Typical Domestic Consumption Values (TDCV), or to £1,663 under the newly revised TDCV. Ofgem lowered its usage benchmark by 7% for electricity and 17% for gas to reflect households using less energy than before, which is why two different headline figures describe the exact same unit rates and standing charges.

The increase traces back to wholesale gas costs, which climbed after the conflict in the Middle East disrupted supply expectations across Europe. Gas bills rose 24% this quarter, while electricity bills rose only 5%, because gas sets the marginal price for a large share of Britain's electricity generation. Despite the rise, typical bills remain 54% (£2,197) below the 2022 crisis peak of £2,500. Adjusted for inflation, the July 2026 cap sits 6% above the same quarter in 2025, which points to an underlying upward cost trend rather than a one-off spike. October–December 2026 is now confirmed at £1,723 (announced 26 August 2026). The next announcement is 25 November 2026 for January–March 2027.

Current Price Cap Rates: What You Pay on the Cap

If you pay by Direct Debit, the October–December 2026 cap sets electricity at 26.32 pence per kWh with a standing charge of 54.83 pence a day (0% VAT on household electricity until 31 March 2027), and gas at 7.97 pence per kWh with a standing charge of 29.68 pence a day (5% VAT included). These are national averages; your region, meter type, and payment method change the exact rate. Typical dual-fuel illustrations: Direct Debit £1,723, standard credit £1,861, prepayment £1,678. Economy 7 Direct Debit electricity-only sits around £1,046. July–September rates (historical) were 26.11p / 57.19p electricity and 7.33p / 29.04p gas. Your payment method alone can shift your annual bill by more than £100, regardless of whether you fix or stay on the cap.

Example: How Much a Fix my Energy Deal Could Save a Higher-Usage Household

Take a household using 2,900 kWh of electricity and 12,000 kWh of gas a year, both above the new typical benchmark of 2,500 kWh and 9,500 kWh. At October–December 2026 cap rates, that household's annual bill runs above the £1,723 typical figure once standing charges are added on top of usage. If a supplier offers a 12-month fix at a unit rate meaningfully below the cap for your usage, you lock in that saving even if January–March 2027 rises. Run your own numbers against your last 12 months of bills rather than the typical household figure. Run your own numbers against your last 12 months of bills rather than the typical household figure, since usage above or below average changes the outcome significantly.

Pros and Cons of Fixing Your Energy Deal

Weigh these points before you commit to a fix.

Pros	Cons
Your unit rate and standing charge stay flat for the whole term, so a cap rise in October or January doesn't touch your bill.	If wholesale gas prices fall sharply, you miss out on a lower cap rate until your fix ends.
Fixed monthly Direct Debit payments make budgeting easier for households and small businesses alike.	Some fixed deals still carry an exit fee of £75 to £100 per fuel, which limits early switching.
Many fixed tariffs now carry no exit fee, so you keep some flexibility even after signing.	Fixing the wrong term, too short or too long, can leave you re-fixing at a worse rate or stuck above the cap.

Fixed or Variable Energy: The Core Difference

A fixed energy tariff locks your unit rate and standing charge for a set contract term, typically 12 to 24 months, regardless of what happens to the Ofgem cap. A standard variable tariff (SVT), also called a default tariff, moves with the price cap every three months. Roughly 22 million UK accounts, 40% of the market, already sit on fixed tariffs and were unaffected by the July rise. Every account still on an SVT saw its bill increase automatically from 1 July.

An electricity contract or gas contract on a fix removes the quarterly guesswork. Your rate stays the same whether the next Ofgem review raises the cap, cuts it, or leaves it flat. Compare current fixed and variable rates with Switch to see where your household sits against the October 2026 £1,723 cap.

When a Fix Energy Deal Makes Sense

Fixing works best when your household matches several of these conditions.

• Your usage exceeds the typical household figure of 2,500 kWh (kilowatt hours) of electricity and 9,500 kWh of gas a year, so cap rises cost you more than average.

• You want one fixed monthly Direct Debit for budgeting instead of a bill that changes every three months.

• A supplier's fixed rate undercuts the current cap rate by 5% or more once standing charges are included.

• You plan to stay at the same address for the full contract term.

• You want protection against whatever the January–March 2027 review (announce 25 November 2026) brings.

When Staying on the Price Cap Makes Sense

Staying on the cap suits households in these four situations.

• No available fixed deal beats the current cap rate by a meaningful margin.

• Market analysts expect wholesale gas prices to fall within the next few months.

• You plan to move house within the next six months.

• You want the freedom to switch supplier at any time without paying an exit fee.

How to Compare Fix Energy Deals

To compare fix energy deals properly, follow five steps.

1. Check your latest bill for your current unit rate, standing charge, and annual usage in kWh.

2. Compare fixed rates from at least three suppliers for both gas and electricity.

3. Calculate the total annual cost using your actual usage, not the typical household figure.

4. Check the contract length and exit fee before signing anything.

5. Confirm the quoted rate already includes Value Added Tax (VAT) and the standing charge, not just the headline unit price.

Switch's energy comparison tool pulls live fixed and variable rates side by side, so you see the annual cost difference in pounds and pence per kWh before you commit to a supplier.

Mistakes to Avoid When You Fix Energy Prices

Avoid these five mistakes when you fix your tariff.

1. Fixing without comparing at least three suppliers first.

2. Ignoring the exit fee, which can run to £75 or £100 per fuel on some contracts.

3. Judging a deal by its headline unit rate alone instead of the total annual cost.

4. Fixing for 24 months when wholesale prices look set to fall, which locks in a rate that ages badly within months.

5. Forgetting to submit meter readings on the day your fix starts, which causes billing disputes later.

Note on Business Energy (no domestic cap)

Ofgem's price cap covers domestic customers only, so commercial gas and electricity contracts are priced individually. Unlike domestic customers, businesses have no automatic switch back to a capped rate at the end of a contract — if you don't renew, many suppliers roll you onto a deemed rate that costs considerably more. This article is for home energy; commercial switching is a separate path.

Does Region Affect Your Fixed or Cap Rate?

Yes, region changes both your cap rate and any fixed quote you receive. Ofgem sets separate unit rates and standing charges for different network areas across England, Scotland, and Wales, since local distribution costs vary. A household in the North East typically sees a different standing charge from one in London or the South West, even at identical usage. Suppliers price fixed tariffs using the same regional cost base, so always compare quotes against your own postcode rather than a national average when you decide whether to fix or stay on the cap.

How to Switch to a Fix Energy Deal

Switching takes four steps once you've picked a deal.

1. Submit your latest meter readings and a recent bill to the new supplier.

2. Sign the new fixed contract and confirm the start date, unit rates, and standing charge in writing.

3. Let your old supplier know only if your new supplier doesn't handle the switch automatically, since most switches are handled between suppliers directly.

4. Take a final meter reading on the switch date and keep it for your records in case of a billing dispute.

The switch itself takes about three weeks from signing to your new rate starting, and there's no interruption to your gas or electricity supply during the process.

Changing Address on a Fixed Energy Deal

Most suppliers let you take a fixed tariff to a new address if you stay with the same supplier and the new home's usage is similar. If the new property's estimated usage differs significantly, the supplier may recalculate your rate or apply an exit fee if you leave the contract instead. Contact your supplier before you move, not after, since some contracts require 48 hours' notice to transfer a tariff to a new address.

Energy Price Outlook After October 2026

Ofgem has confirmed the October–December 2026 typical dual-fuel Direct Debit figure at £1,723 (announced 26 August 2026). The next announcement is 25 November 2026 for January–March 2027. Fixed deals agreed now protect against that next move for the length of the contract, while households on the cap carry the quarterly risk. Full details on the current cap sit on Ofgem's official price cap page.

The cap has swung sharply over the past four years. It peaked at £2,500 during the 2022 crisis under a government support scheme, fell back through 2023 and 2024 as wholesale prices eased, and dropped again in April 2026 to £1,477 once a £150 average reduction from the autumn budget took effect. The July 2026 rise to £1,663 (or £1,862 under the old benchmark) reverses part of that fall. This pattern shows the cap moves in both directions depending on wholesale markets and government policy, which is exactly the risk a fixed tariff removes for the length of your contract. Anyone asking whether gas prices will go up or electric prices are going up should treat the cap as a quarterly snapshot, not a fixed forecast, since the next review can move it either way.

The bottom line: a fix energy deal protects you against the next quarterly move (Jan–Mar 2027), provided the rate you lock in genuinely beats the current £1,723 price-cap sketch for your usage.

Frequently Asked Questions

Is it worth fixing energy prices now in October 2026?

Yes, it's worth fixing if a supplier's rate beats the current £1,723 cap and you can commit to the full contract term. Compare at least three fix energy deals against your actual usage before deciding, since some tariffs only beat the cap for low-usage households.

Should I fix my energy tariff or stay on the price cap?

Fix your tariff if a deal undercuts the cap by 5% or more and you won't move house soon. Stay on the cap if no deal beats the £1,723 sketch, or if you expect wholesale gas prices to fall before the January–March 2027 review.

Will my fixed energy tariff increase during the contract?

No, a fixed energy tariff keeps the same unit rate and standing charge for the whole contract term. Ofgem's quarterly cap changes only affect standard variable tariffs, not fixed deals already in place.

Is now a good time to fix energy prices in the UK?

Yes — compare any fix against the current £1,723 October–December sketch. Locking a competitive rate protects you from whatever January–March 2027 brings (announce 25 November 2026).

What happens if I move house during a fixed energy deal?

Most suppliers let you transfer the same fixed tariff to a new address if usage is similar, though some apply an exit fee instead. Contact your supplier at least 48 hours before moving to confirm which option applies.

Are there exit fees for fixing energy prices in 2026?

Yes, some fixed tariffs charge an exit fee of £75 to £100 per fuel if you leave before the contract ends. Many suppliers now offer exit-fee-free fixed deals, so check the terms before signing.

When does the next Ofgem price cap change happen?

October–December 2026 is already in force at £1,723. Ofgem announces the January–March 2027 cap on 25 November 2026; that change takes effect on 1 January 2027 and applies to standard variable tariffs only.
