Fast answer: what’s the cheapest fixed tariff after the July cap?

There isn’t one single “cheapest fixed tariff” for everyone in the UK after the July Ofgem price cap update. The cheapest fixed deal depends on your region, meter type (standard / Economy 7 / smart / prepayment), payment method (monthly Direct Debit vs pay on receipt), usage and tariff eligibility (some fixed deals are limited to certain meter setups or require smart meters).

How to get the cheapest fixed for you: compare whole-of-market fixed tariffs using your actual postcode and meter details, then weigh up unit rates + standing charges and the exit fee and contract length.

Key takeaways (July cap context)

  • The cap limits unit rates, not your bill. Your total cost still depends on how much energy you use.
  • Fixed deals can beat the cap for some homes, but not always once standing charges and exit fees are included.
  • Direct Debit tariffs are often cheaper than pay-on-receipt, and prepayment options can differ again.
  • Economy 7 users must compare day/night rates (not just a single “average” unit rate).

When fixing is more likely to suit you

  • You want predictable unit rates for budgeting.
  • You’re happy to commit for 12–24 months (or choose a shorter fix).
  • You can avoid exit fees by choosing a low/no-exit-fee tariff or you’re confident you’ll stay for the term.
  • You’re not reliant on a tariff that could change (for example, you’re not switching meters imminently).

Fixed vs the July price cap: what to compare (beyond the headline)

When people search for the “cheapest fixed tariff after the July cap”, they often mean the cheapest overall option for their home. That depends on how a fixed tariff’s unit rates and standing charges stack up against a cap-priced variable tariff in your region, plus the risks of exit fees if prices fall later.

What matters Fixed tariff Cap-priced variable What to watch for
Unit rates Locked for the term Can change with each cap period Compare electricity and gas separately, and day/night if Economy 7
Standing charges Usually fixed, can be higher/lower Capped, but varies by region A “cheap unit rate” can be offset by a higher standing charge
Exit fees Often applies (per fuel) Typically none If prices drop, leaving early can wipe out savings
Payment method Direct Debit often lowest Direct Debit vs other methods differ Make sure you compare on the same payment basis
Eligibility May require smart meter / online billing Usually widely available Check meter compatibility (Economy 7, prepay, smart)

Decision checklist: does fixing make sense?

More likely to suit you if:
You value certainty and will keep the tariff for most of the term.
The fixed deal’s total estimated annual cost is lower (not just the unit rate).
Exit fees are low enough that you could still switch later if needed.
Less likely to suit you if:
You may move home soon or you’re changing meter type (e.g., to or from Economy 7).
The tariff has high exit fees and you think prices could fall within your contract.
You’re on prepayment and the fixed options available to you are limited.

Two realistic scenarios (illustrative numbers)

These examples show why the “cheapest fixed” can change by household. Figures are estimated and simplified to illustrate the decision; your actual quote will use your postcode and current market rates.

  • Scenario A (typical dual-fuel, Direct Debit): Annual use 2,700 kWh electricity + 11,500 kWh gas. If a fixed deal is ~£110/year cheaper than a cap-priced variable for your region and has a £50 exit fee per fuel, you’d want to stay at least ~11 months to break even on fees (assuming you’d otherwise switch away).
  • Scenario B (electricity-only flat, low use): Annual use 1,600 kWh electricity. A fixed tariff that saves 1p/kWh but adds 8p/day to the standing charge could end up costing around £13/year more (1,600×£0.01 = £16 saved; 365×£0.08 = £29 added; net +£13). For low users, standing charges often decide “cheapest”.

Important: Economy 7 users should run comparisons using a realistic day/night split. A deal can look “cheapest” on a single blended rate but be expensive if your usage is mostly daytime.

Costs, exclusions and common pitfalls (so you don’t pick the wrong “cheap” tariff)

A fixed tariff can be “cheap” on paper but poor value in practice. These are the most common reasons a switch looks good initially and disappoints later.

1) Standing charges outweigh unit-rate savings

If you’re a low user (or electricity-only), a higher standing charge can cancel out a “cheaper” unit rate. Always compare the estimated annual cost, not one line on the tariff.

2) Exit fees limit flexibility

Fixed deals often charge exit fees per fuel. If prices fall after the July cap period, leaving early can wipe out any gains. Look for low/no exit fees if you want flexibility.

3) Economy 7 comparisons done wrong

Economy 7 has separate day/night rates. If your night usage is low (e.g., you don’t charge an EV overnight), a “cheap” E7 tariff can cost more than a single-rate tariff.

4) Payment method mismatches

Quotes can differ significantly between monthly Direct Debit and pay-on-receipt. Make sure the tariff you choose matches how you’ll actually pay.

5) Meter / tariff eligibility surprises

Some fixed deals are limited (e.g., online-only, paperless billing, smart meter requirements). If you’re on prepayment or have a complex meter setup, choice can be narrower.

6) Not checking contract end and renewal rules

When a fix ends, suppliers typically move you to a variable tariff. Put the end date in your calendar and review options before renewal.

Renter / landlord note: you can usually switch supplier if you pay the bills, but check your tenancy agreement. If your landlord includes energy in rent or you’re on a communal / heat network, you may not be able to switch in the normal way.

FAQs: cheapest fixed tariff after the July cap (UK)

Is the Ofgem price cap the cheapest tariff?

Not necessarily. The cap sets a maximum on unit rates and standing charges for standard variable and some default tariffs. Some fixed deals can be cheaper (or more expensive) depending on your region, meter type and payment method.

When do fixed tariffs change after the July cap update?

Suppliers can reprice fixed deals at any time. Around cap changes, fixed pricing can shift quickly as wholesale costs and competitive pressure change. That’s why comparing with your postcode and meter details is more reliable than relying on a single headline deal.

What information do I need to find the cheapest fixed deal?

Best: your postcode, current supplier, payment method, meter type and annual usage in kWh for gas and electricity. If you don’t know usage, a comparison can still estimate—just treat results as indicative, especially for Economy 7.

Do I need a smart meter to get the cheapest fixed tariff?

Not always. Some tariffs are open to standard meters, while others are designed for smart meters (or require half-hourly settlement features). If you don’t have a smart meter, you can still access many competitive fixed deals—availability varies by supplier and region.

Can I switch if I’m in debt to my current supplier?

It depends. Rules vary by situation and meter type (including prepayment). If you’re struggling, you can get free guidance from Citizens Advice and your supplier may be able to offer a repayment plan. It’s important to address debt before switching, as it can restrict options.

How long does switching take and will my supply be interrupted?

Switching is typically completed within a few working days for most households, and you should not lose supply—energy still comes through the same pipes and wires. Timings can differ if there are meter issues, address matching problems, or complex setups.

Do fixed tariffs always have exit fees?

Many do, but not all. Exit fees can be charged per fuel and can vary by supplier and contract length. If you want the option to switch again if prices fall after July, prioritise low/no exit fee options when comparing.

Is it cheaper to fix gas and electricity together (dual fuel)?

Not always. Some suppliers offer dual-fuel discounts, but sometimes the cheapest approach is to take gas and electricity with different suppliers. Whole-of-market comparison helps you see both options clearly.

Trust, methodology and sources

Editorial accountability

How we assess “cheapest fixed” (our approach)

For this guide, “cheapest” means the lowest estimated annual cost available to a household based on postcode region, meter type and payment method—not simply the lowest unit rate. We encourage users to verify tariff details before switching.

  • Inputs we prioritise: postcode (region), payment method, meter type, and (where provided) annual kWh.
  • What we compare: fixed-rate tariffs available through our comparison journey, alongside a cap-priced variable reference where relevant.
  • What we surface: contract length, exit fees (per fuel), standing charges and unit rates.
  • Limitations: tariff availability can change daily; some deals are restricted (e.g., smart meter requirements, online-only management); and estimated costs depend on accurate usage data.

Transparency note: We cannot display a universal “cheapest fixed tariff” on this page because UK pricing varies by region and household. Your quote is the reliable way to identify the cheapest eligible option for you.
