Fast answer
The E.ON Next Next Fixed 24m Exclusive tariff explained is a 24‑month fixed energy deal where your unit rates and standing charges are set for the full term (unless the supplier changes them for reasons allowed by the contract). It can suit you if you want bill predictability, but you should check exit fees, how you pay, and whether your meter type is accepted.
What “24m fixed” means
Your price per kWh and daily standing charge don’t move with the wider market during the fixed term, which helps budgeting.
What “exclusive” often signals
It may be limited to certain customers, channels, meter types or payment methods. Eligibility can change, so verify via a live quote.
The one check people miss
Exit fees (and when they apply). A 24‑month fix can be great until you need to move, rent out, or switch early.
We don’t publish “example unit rates” for this tariff because tariffs change and rates vary by region, meter and payment method. Use the quote journey to see the live tariff details for your postcode.
What this tariff is (and what it isn’t)
A fixed tariff is mostly about certainty. If the wholesale market goes up or down during your fix, your rates usually stay the same. That’s the upside and the trade‑off in one sentence.
What you’re paying is still built from two moving parts:
- Unit rate (p/kWh)
- The price for each unit of gas or electricity you use. This is where efficiency improvements (insulation, heating controls) make the biggest difference.
- Standing charge (p/day)
- A daily amount that helps cover network costs and metering. Even very low‑use households can feel this, so it’s worth checking the balance between unit rate and standing charge.
A fixed tariff isn’t the same thing as the Ofgem price cap. The cap applies to standard variable tariffs (SVTs) and sets a maximum level for typical charges, but a fix is a separate contract price that can sit above or below the SVT depending on the market.
What you should check on the tariff facts
Before you sign up, look for these items on the tariff information label / summary:
- Term length (24 months) and whether the price is fixed for the whole period.
- Exit fees (if you leave before the end).
- Payment method options (Direct Debit, prepayment, receipt of bills).
- Meter type support (credit meter, smart meter, prepay; and if there are restrictions).
- What happens at the end of the fix (rolls to a variable tariff unless you choose another).
Compare the live deal for your postcode
We’ll show whole‑of‑market options you can actually get where you live, including fixed deals and alternatives. No guesswork.
If you’re moving home, you can still compare. Just use the postcode you’ll be responsible for paying at.
Two realistic scenarios (illustrative)
These aren’t quotes and they aren’t E.ON Next rates. They’re here so you can sanity‑check how a 24‑month fix behaves over time. The numbers use a simple model and rounded figures.
Scenario A: small flat, low use
Assumptions: 1 adult in a 1‑bed flat, gas & electricity, low usage pattern; you’re comparing two tariffs that both start at about the same annual cost.
If the variable tariff rises by an average of £12/month across year 2 (market changes), the 24‑month fix could avoid roughly £144 of extra cost over those 12 months. If the variable falls by £12/month, the fix could cost roughly £144 more instead.
Scenario B: family home, higher use
Assumptions: 3–4 person household, higher heating demand; you’re again comparing tariffs that begin at a similar starting cost.
A smaller change in unit rates can matter more because you use more energy. If your variable option ends up averaging £25/month higher through year 2, a fix could avoid about £300 over the year (or cost about £300 if the market goes the other way).
Why we model it this way: without live regional unit rates we can’t responsibly publish p/kWh examples for a named tariff. What we can do is show the effect of “fixed vs variable” using monthly deltas you can relate to.
Compare a 24‑month fix against common alternatives
You don’t need to be an expert to choose well. The trick is matching the tariff type to your situation: stability, flexibility, or the ability to shift usage. Here’s a quick way to think about it.
| Option | Best for | Main upside | Main catch |
|---|---|---|---|
| 24‑month fixed tariff (like “Next Fixed 24m Exclusive”) | Budgeting and stability for 2 years | Predictable rates for the term | May have exit fees; could miss out if prices fall |
| Shorter fixed tariff (e.g. 12 months) | People who want some stability but not for 2 years | Less commitment; easier to review sooner | You re-face the market earlier; exit fees may still apply |
| Standard variable tariff (SVT) | Flexibility, moving home soon, avoiding exit fees | Can usually leave without a penalty | Price can change; budgeting is harder |
| Time-of-use tariffs (where available) | Households that can shift electricity use | Potentially lower costs at certain times | Not always available; can be expensive at peak times if habits don’t change |
Quick checklist: likely to suit you
- You plan to stay in the property for at least a year or two.
- You’d rather know what your rates will be than take a punt on future price changes.
- You’re happy with the payment method required (often Direct Debit).
- You’ve checked any exit fees and you’re comfortable with them.
Quick checklist: think twice
- You may move, split up, or change who pays the bills soon.
- Your usage is unusual (very low use where standing charges dominate).
- You’re trying to keep maximum flexibility, even if prices rise.
- You’re on a meter setup that sometimes has fewer deals available (common with some prepay arrangements).
If you’re unsure, compare both: a 24‑month fix and your supplier’s SVT equivalent. The difference you care about isn’t the headline “fixed” label — it’s the total estimated annual cost for your actual usage and region.
Costs, exclusions and common pitfalls
This is the stuff that causes “I wish I’d known” messages. None of it is complicated, but it’s easy to skip when you just want your switch done.
Exit fees
Many fixed tariffs charge a fee if you leave early. Check the amount, whether it’s per fuel, and when it applies (some waive it near the end of the term).
Payment method differences
Rates can differ depending on whether you pay by Direct Debit, on receipt of bill, or prepayment. Always compare like‑for‑like.
Meter type and tariffs
Some deals are only offered on certain meter types. If you’re on prepay or you have a complex setup, your available tariffs can be narrower.
What happens when the fix ends
In the UK, suppliers typically move you onto another tariff (often their standard variable tariff) if you do nothing. Put a reminder in your calendar a month or two before the end date so you can compare again.
Moving home during a fixed tariff
You can usually close an energy account when you move, but the rules on fees and transferring a tariff aren’t identical across suppliers. If a move is likely in the next 24 months, check the supplier’s terms before committing.
Tip from our editors: if the only thing attracting you is the word “exclusive”, slow down and treat it like any other tariff. The decision should come from the total estimated annual cost for your usage, plus the exit-fee risk.
FAQs
Is E.ON Next Next Fixed 24m Exclusive definitely available in my area?
Not always. UK tariff availability can vary by region, meter type and payment method. The safest way to confirm is to run a live comparison using your postcode and current meter details.
Does a 24‑month fixed tariff protect me from the Ofgem price cap changing?
A fixed tariff price is set by your contract, not by the price cap. The Ofgem cap limits the maximum level of charges on standard variable tariffs, while a fix stays at its agreed rates for the term (subject to the contract terms).
Will I pay exit fees if I switch away before the 24 months end?
Possibly. Many fixed deals include exit fees, often per fuel. The exact amount and any “no-fee” window varies by tariff, so check the tariff summary before you agree to switch.
Can I get this tariff if I have a prepayment meter?
It depends on the supplier and the specific tariff rules, and it can change over time. If you’re on prepay, compare using your actual meter/payment setup so you only see tariffs you can take.
If I switch, will my supply go off?
No. In the UK, switching supplier doesn’t interrupt your gas or electricity supply. Your energy still comes through the same pipes and wires; only the billing supplier changes.
How long does it take to switch energy supplier in the UK?
Switching times can vary, but many switches complete within a few working days under modern switching arrangements. Your new supplier should confirm the expected date during sign-up, and you’ll still be billed by your old supplier until the switch completes.
What information do I need to compare this tariff properly?
At minimum: your postcode and whether you have gas, electricity or both. For the best match, add how you pay (e.g. Direct Debit or prepay) and an estimate of your annual usage from recent bills.
What happens if I do nothing when my fixed tariff ends?
You’ll usually be moved onto another tariff (often a standard variable tariff) unless you choose a new deal. Set a reminder to compare before the end date so you can decide with up-to-date prices.

How we assess this tariff type
Because we don’t have your postcode, usage and meter setup inside this article, we can’t responsibly state what this specific tariff costs you. Instead, we assess the decision using factors that materially affect UK households:
- Contract risk: exit fees, term length, and what happens at the end of the fix.
- Bill drivers: the balance of unit rates vs standing charges for low-use and high-use homes.
- Eligibility friction: common restrictions (payment method, meter type), without assuming any apply to this tariff until you see the live product details.
- Comparison fairness: we encourage comparing on estimated annual cost for the same usage and payment method, not on headline labels.
Limitations: the scenarios above are illustrative models only. Live tariff pricing, fees and availability can change quickly and vary by region. Always confirm details in the quote flow and the supplier’s tariff summary.
