Compare fixed tariffs after the price cap — personalised to your postcode
The Ofgem price cap limits what suppliers can charge on default and standard variable tariffs (SVTs), but it does not cap fixed deals. That’s why the “cheapest fixed energy tariff after the Ofgem price cap” depends on your region, meter type and household usage.

Why consider a fixed tariff after the Ofgem price cap changes?
Predictable unit rates
A fixed tariff typically keeps your unit rate and standing charge stable for the contract term. That can make budgeting simpler when the cap moves up or down.
Protection from rises
If wholesale prices increase and the next cap rises, a fixed deal can help shield you from higher SVT prices until your fix ends.
Choice beyond the cap
The cap doesn’t tell you the cheapest deal available. A whole-of-market comparison can uncover competitive fixed tariffs that may beat your current SVT for your usage.
Important: a fixed tariff isn’t automatically better. If the cap falls (or your usage changes), your SVT may become cheaper. Always compare total annual cost and check exit fees before committing.
Ofgem price cap explained (and why it doesn’t equal your bill)
What the cap is
The Ofgem price cap is a limit on the unit rate and standing charge suppliers can set for customers on default tariffs (including SVTs). It applies across Great Britain and is updated regularly.
It’s designed to prevent unfair pricing — it’s not a guarantee that everyone pays the same amount.
Why your bill varies
- Your kWh usage (the cap is based on a typical household, not your home)
- Where you live (regional network costs affect standing charges)
- Meter type (e.g. Economy 7 has different day/night rates)
- Payment method and tariff type (fixed vs variable)

How to choose the cheapest fixed energy tariff (for your home)
The cheapest fixed tariff isn’t always the one with the lowest unit rate. Use these checks to make sure you’re comparing like-for-like and avoiding nasty surprises.
- Start with your usage: find your annual kWh on a recent bill (or use a smart meter summary). Accurate usage makes the “cheapest” ranking meaningful.
- Compare total annual cost: include both unit rate and standing charge. A low unit rate can be offset by a high standing charge (and vice versa).
- Check contract length: 12-month fixes offer flexibility; longer fixes can provide longer price certainty. Choose based on your risk preference and moving plans.
- Review exit fees: if you want the option to switch again quickly, prefer low or no exit fees.
- Match your meter type: Economy 7 and prepayment tariffs price differently. Ensure the quote is for your actual meter setup.
- Consider customer service and billing: the cheapest tariff is only “best” if billing is reliable. Look at customer feedback and support hours.
If you’re on a standard variable tariff (SVT)
SVT rates can change when the Ofgem cap updates. If you’re happy with flexibility, you may prefer to stay variable. If you want stability, compare fixed deals and see the estimated difference for your usage.
If you’re already fixed
Check your tariff end date and exit fee. You can often switch without penalty in the final weeks of your contract. Compare now and set a reminder so you don’t roll onto an SVT unexpectedly.
Regional pricing: why your postcode matters
Energy prices aren’t uniform across the UK. Standing charges and unit rates can differ because of regional electricity distribution networks and local cost factors. That means a tariff that’s cheapest in one region may not be cheapest in another.
Tip: If you’ve recently moved (or you’re about to), compare again once you have the new postcode and meter details — the ranking of cheapest fixed tariffs can change.
Common mistakes when searching for the cheapest fixed tariff
Comparing without usage
A “cheap” unit rate doesn’t guarantee a cheaper year overall. Always compare using your estimated annual kWh for realistic results.
Ignoring standing charge
Standing charge can significantly impact low-usage homes. Compare both components, not just the headline unit rate.
Missing exit fees
If you switch again before the fix ends, exit fees can wipe out savings. Factor flexibility into your decision.
Quick checklist before you switch
- Is the quote based on your meter type and payment method?
- Are you comparing the same fuel setup (dual fuel vs electric-only)?
- Have you checked the tariff end date and any exit fees?
- Do you have a smart meter or plan to get one (some tariffs work best with smart readings)?
FAQs: cheapest fixed tariff after the Ofgem price cap
Is a fixed tariff always cheaper than the price cap?
No. The cap limits SVT prices, but fixed deals can be above or below SVT pricing depending on market conditions, your region and your usage. The reliable way to know is to compare total annual costs for your postcode.
Does the Ofgem price cap apply to fixed tariffs?
Not usually. The price cap is primarily for default/SVT tariffs. Fixed tariffs have their own contract terms and pricing, which is why shopping around can be worthwhile after a cap change.
What information do I need to compare fixed energy deals accurately?
- Your postcode
- Whether you want gas and electricity together (dual fuel) or single fuel
- Your annual kWh usage (from a bill or online account)
- Meter type (smart/standard, prepay, Economy 7)
- Payment method (e.g. monthly Direct Debit)
Will switching interrupt my gas or electricity supply?
No. A supplier switch is an admin change. Your energy keeps flowing as normal, and your new supplier coordinates the handover.
Can I switch if I have a prepayment meter?
Often yes, but availability can vary by supplier and circumstances. Compare using the correct meter type to see options that are actually available for prepayment.
How quickly can I switch to a fixed tariff?
Switch times can vary, but many switches complete within a few working days. You’ll receive updates from your new supplier about timings and any actions needed (like providing meter readings).
Still unsure? Use the comparison form and review the cheapest fixed options alongside key contract terms.
