How to switch to a fixed energy tariff before the April price rise
Compare whole-of-market fixed deals for your home in minutes and switch before April—so you can lock in a rate (subject to availability) and avoid last-minute stress.
- Whole-of-market comparison (not just a handful of suppliers)
- Check exit fees, unit rates and standing charges side-by-side
- Quick form to see suitable fixed tariffs for your postcode
- Switching is usually seamless—no engineer visit for standard meter changes
Home energy only. Switching timelines vary by supplier and meter type. Prices and availability can change quickly, especially ahead of April.
Compare fixed energy tariffs and switch before April
If you’re currently on a variable tariff, an April price rise can mean higher unit rates and standing charges. A fixed tariff can help you budget by locking in rates for a set term (for example, 12 or 24 months). With EnergyPlus, you can compare whole-of-market home energy deals and start a switch online.
To show accurate options, we’ll ask for your postcode and basic details. If you have a recent bill to hand, you can also use your annual usage (kWh) for even better comparisons—especially when unit rates are close.
Tip for switching ahead of April
Many switches complete within around 5 working days, but timing can vary. If you’re aiming to beat an April change, start your comparison as early as you can and double-check exit fees and tariff details.

What does “switching before April” actually mean?
Energy prices in the UK are typically reviewed on a schedule that can lead to changes around April. If you’re on a variable tariff, your rates may move when the market changes. Switching to a fixed deal before April aims to secure a rate for a set period—so your unit rates and standing charges stay the same during the fixed term (unless your contract states otherwise).
You can switch whether you pay by Direct Debit or on receipt of bill, and whether you have a standard meter or a smart meter. If you rent, you can usually switch as long as you pay the energy bills and your tenancy agreement doesn’t restrict supplier choice.
Why consider fixing your energy tariff before April?
Budget certainty
A fixed tariff can make household budgeting easier because your unit rate and standing charge are set for the term. That can be useful when prices are expected to rise in April.
Avoid last-minute decisions
Comparing early gives you time to check the numbers properly—rates, term length, exit fees and payment method—rather than rushing close to a price change.
Whole-of-market view
Not all fixed deals are good value. A whole-of-market comparison helps you see competitive options across multiple suppliers, instead of relying on a single provider’s offer.
More control over risk
If prices rise, a fixed rate can protect you. If prices fall, you may pay more than new deals—so it’s important to balance stability against flexibility.
No interruption to supply
Switching supplier doesn’t mean your gas or electricity goes off. In most cases, it’s a paperwork switch and your meters stay the same.
If you’re unsure, you can start by checking whether you’re currently on a standard variable tariff (SVT) or an existing fixed deal, then compare what a new fixed tariff would cost for your usage.
Step-by-step: how to switch to a fixed tariff before April
- Check your current tariff and end date. Look for your tariff name, whether it’s fixed or variable, and any exit fees. If you’re still in a fixed term, consider whether any early exit fee is worth paying.
- Gather your usage (if possible). Your annual gas and electricity usage in kWh provides the most accurate comparison. If you don’t have it, you can still start with your postcode and household basics.
- Compare fixed deals whole-of-market. Focus on the unit rate, standing charge, tariff length, payment method requirements and customer service considerations.
- Choose a fixed tariff and submit your switch. The new supplier will contact your current supplier and manage the process. You’ll receive confirmation of your contract and key terms.
- Take a meter reading on switch day. This helps ensure your final bill from your old supplier and your first bill from your new supplier are accurate.
- Keep an eye on your Direct Debit. A new supplier may set an initial Direct Debit based on estimated usage. Review it after your first bill, especially if you’ve changed how you heat your home.
How early should you start?
If your goal is to have a new tariff in place ahead of April, compare and apply as soon as you can. Switching can be quick, but it isn’t guaranteed—supplier checks, meter types and administration can affect timelines.
What to check when choosing a fixed energy tariff
A fixed tariff is not automatically the “best” tariff. The right option depends on your household usage, how long you plan to stay in the property, and how you feel about price certainty versus flexibility. Use this checklist before you switch.
| Tariff feature | Why it matters before April | What to look for |
|---|---|---|
| Unit rate (p/kWh) | This drives most of your cost—especially for high-usage homes. | Compare electricity and gas unit rates across deals; don’t judge by Direct Debit alone. |
| Standing charge (p/day) | You pay it regardless of usage; it impacts low-usage households most. | Check both fuels and your region; standing charges vary by distribution area. |
| Fixed term length | Longer terms can protect you for longer, but can reduce flexibility. | Choose a term that matches your plans—especially if you may move home. |
| Exit fees | You may need to pay to leave early if the market changes. | Confirm the fee per fuel and whether it reduces as the contract nears the end. |
| Payment method | Some deals are priced for Direct Debit and can differ for pay-on-receipt. | Make sure the quote matches how you prefer to pay. |
| Smart meter / meter type | Your meter can affect eligibility for certain tariffs (e.g. time-of-use). | If you have Economy 7, prepayment, or smart meter, check tariffs that suit your setup. |
Avoid a common comparison mistake
Don’t compare tariffs based only on the estimated monthly Direct Debit. Always check the unit rate and standing charge—especially if your usage changes seasonally (for example, electric heating or a heat pump).
Costs, exit fees and what switching might mean for your bills
Will I pay to switch?
Switching supplier is usually free. The main potential cost is an exit fee if you leave an existing fixed contract early. Some suppliers also set minimum terms or conditions.
If you’re on a standard variable tariff, there’s typically no exit fee—so you can switch to a fixed deal at any time.
Could a fixed tariff cost more?
Yes. If the market falls after you fix, new deals might be cheaper. That’s why it’s important to compare the full tariff details (unit rate + standing charge) and consider how much stability is worth to your household.
Quick pre-April checklist
- Check if you’re currently fixed or variable (and the contract end date).
- Look for exit fees per fuel (gas and electricity can be separate).
- Confirm your payment method (Direct Debit vs on receipt of bill).
- Use annual kWh if available for accuracy.
- Apply early to give enough time before April.
Moving home? If you’re likely to move soon, consider shorter fixed terms or check whether the supplier allows you to take the tariff with you (not always possible).
Is it worth fixing if I use very little energy?
Low-usage households should pay close attention to standing charges. A tariff with a low unit rate but higher standing charge can cost more overall if you don’t use much gas or electricity.
Regional differences: why quotes vary by postcode
In Great Britain, energy prices can vary by region because of differences in network costs and distribution areas. That’s why a fixed tariff that looks strong in one region may not be best value in another.
Standing charges vary
Your standing charge depends on your electricity and gas distribution region. Comparing with your postcode helps ensure the rates shown are relevant.
Different tariff availability
Some suppliers restrict certain fixed deals by region or meter type. A whole-of-market comparison helps surface what’s actually available to you.
Northern Ireland differs
Energy markets and suppliers differ in Northern Ireland. If you’re in NI, check that you’re comparing the right set of home energy options for your region.

FAQs: switching to a fixed tariff before April
Can I switch if I’m in a fixed contract?
Usually yes, but you may pay an exit fee for leaving early. Check your current supplier’s terms and compare the fee against the potential savings and the benefit of price certainty.
Will my supply be interrupted?
No. Your gas and electricity continue as normal during a supplier switch. The process is administrative; you don’t need to change pipes or cables.
Do I need a smart meter to access fixed deals?
Not necessarily. Many fixed tariffs are available to standard meters too. However, certain time-of-use tariffs may require a compatible smart meter.
What if I have Economy 7?
Economy 7 has separate day and night rates. Make sure you compare tariffs that match your meter setup and your actual day/night usage split.
Is a dual fuel deal always cheaper?
Not always. Some suppliers price competitively for dual fuel, but it can still be worth checking separate suppliers—especially if your gas and electricity usage is very different.
How do I avoid choosing the wrong tariff?
Focus on total cost for your usage, not just the headline rate. Check the unit rate and standing charge, the tariff term, and whether there are exit fees.
Still not sure whether to fix?
Submit the form above and compare your options. You can review deal details and decide whether a fixed tariff is right for your household before you proceed.
