Find the cheapest fixed rate energy now — tailored to your home
“Cheapest” depends on your postcode, meter type (standard, smart, prepayment, Economy 7), payment method, and how much energy you use. That’s why the best way to find the cheapest fixed tariff right now is to compare whole-of-market options using your details.
Use the form to request a personalised comparison. We’ll use the details you provide to match you with eligible fixed-rate home energy deals, showing the key costs that matter:
- Unit rates (pence per kWh) for electricity and gas
- Standing charges (daily cost) — often the deciding factor for low usage homes
- Exit fees and fixed term length (e.g. 12 or 24 months)
- Estimated annual cost based on your usage (where available)
Good to know: A fixed tariff typically locks your unit rates and standing charges for the term. That can protect you from price rises, but may include exit fees if you leave early.

Already in a fixed tariff? Check your end date and any exit fees first. If your contract is close to ending, switching to a cheaper fixed deal may be simpler and lower-risk.
What “cheapest fixed rate energy” usually means in the UK
Most people search for the cheapest fixed energy deal because they want predictable bills. In practice, the cheapest fixed tariff is usually the one with the best balance of:
- Competitive unit rates for your region
- Reasonable standing charges (especially important if you’re out during the day)
- Low or no exit fees, if flexibility matters
- A term length that matches your plans (moving home, renovations, etc.)
Why consider a fixed energy tariff now?
More predictable monthly costs
A fixed tariff can help you plan ahead because your unit rates and standing charges are set for the term (subject to contract terms).
Protection from price rises
If prices increase during your fix, you won’t pay those higher rates. That can be valuable in volatile periods.
Clear comparison of true cost
Comparing fixed deals side-by-side makes it easier to weigh unit rates, standing charges and any exit fees before you switch.
Potential savings vs your current tariff
If you’re on a more expensive tariff, a cheaper fixed deal could reduce your annual bill (depending on usage and regional pricing).
Better fit for your meter & lifestyle
Some fixed deals suit Economy 7, smart meters or prepayment better than others. Comparing whole-of-market helps you find a fit.
Confidence from transparent terms
A good fixed tariff makes the key terms easy to understand: contract length, exit fees, payment method and customer support options.
How to get the cheapest fixed energy deal (step-by-step)
- Share your details — postcode, and your contact details so we can send you relevant options.
- We compare whole-of-market fixed tariffs — focusing on deals available for your home, region and meter type.
- Review the key costs — unit rates, standing charges, contract term and any exit fees.
- Choose with confidence — if you decide to switch, you’ll know what you’re agreeing to and what it could cost over the year.
Tip: If you have a recent bill or online account, note your annual usage (kWh). Comparing on usage is the most reliable way to identify the true cheapest fixed rate for you.
What counts as a “fixed rate” tariff?
A fixed rate energy tariff is a contract where the supplier sets your unit rate (p/kWh) and standing charge for a fixed period (often 12–24 months). Your bill can still change if your usage changes, but the rate you pay per unit stays the same for the term (subject to the supplier’s terms).
Some tariffs may include perks (e.g. smart meter programmes) or require a specific payment method. Always check the tariff information before switching.
What to check before choosing the cheapest fixed rate energy
The cheapest fixed deal on paper isn’t always the cheapest in real life. Use this checklist to avoid surprises and choose a tariff that works for your household.
| What to compare | Why it matters | Quick UK tip |
|---|---|---|
| Unit rate (p/kWh) | Directly affects the cost of every unit of energy you use. | Compare electricity and gas separately; some deals are strong on one and weaker on the other. |
| Standing charge | A daily charge you pay regardless of usage. | Low-usage households should watch this closely. |
| Contract length | Longer fixes can offer certainty, but may reduce flexibility. | If you may move soon, a shorter term or low exit fee can be safer. |
| Exit fees | Cost to leave before the end of the fixed term. | Check whether fees apply per fuel (gas and electricity). |
| Meter type | Some tariffs require or exclude certain meters. | Economy 7 has day/night rates — compare both. |
| Payment method | Direct Debit vs pay on receipt can change pricing. | If you can pay by Direct Debit, you may see more fixed options. |
Regional pricing note: Energy prices vary across Great Britain due to regional distribution costs. The cheapest fixed rate energy in London may not be the cheapest in Manchester, Cardiff, Glasgow or rural areas.
Common mistakes when hunting for the cheapest fixed tariff
Comparing only the headline monthly amount
Your monthly Direct Debit can be an estimate. The real comparison is based on unit rate + standing charge and how much energy you actually use.
Ignoring standing charges
A tariff can have a low unit rate but a higher standing charge. For low usage homes, that can make it more expensive overall.
Not checking exit fees on your current deal
If you’re mid-contract, exit fees may outweigh any short-term savings. It’s still worth checking — but do the maths.
Choosing the longest fix by default
Longer fixes can be great for certainty, but if prices fall you may be locked in. Consider your appetite for flexibility.

Cheapest fixed rate energy now: FAQs
Is a fixed tariff always cheaper than a variable tariff?
Not always. A fixed tariff can be cheaper or more expensive depending on market pricing at the time you switch and your region. Many people choose fixed tariffs for certainty rather than guaranteed savings. The best approach is to compare based on your usage and check the total estimated cost.
Can I switch fixed energy deals if I’m renting?
In many cases, yes — if you pay the energy bills and have the account in your name, you can usually choose your supplier. If bills are included in rent or the landlord manages the account, you may not be able to switch. It’s worth checking your tenancy agreement.
Does my postcode affect fixed energy prices?
Yes. Energy prices vary across Great Britain due to regional network charges and other factors. That’s why we ask for your postcode — it’s essential for showing the cheapest fixed rate energy options available to you.
What if I have a prepayment meter or Economy 7?
You can still compare and switch, but availability can differ. Economy 7 tariffs have separate day and night rates, and prepayment tariffs may have fewer options. Whole-of-market comparison helps identify the best fixed choices for your meter type.
How quickly can I switch to a new fixed tariff?
Switching times can vary by supplier and circumstances, but many switches complete within a few working days to a couple of weeks. Your energy supply won’t be interrupted — only the billing changes.
Will I pay exit fees if I leave my current fixed deal?
Possibly. Many fixed tariffs include exit fees if you leave before the end date. Check your current tariff terms or latest bill. If you’re close to the end of your contract, exit fees may not apply (depending on your supplier’s rules).
