Compare cheap fixed energy tariffs for winter 2026
If you’re searching for cheap fixed energy tariff deals in the UK for winter 2026, you’re usually trying to do two things at once: keep bills as low as possible and avoid nasty surprises when heating demand goes up. Fixed tariffs can help by locking in unit rates and standing charges for a set term (e.g. 12, 18 or 24 months).
EnergyPlus.co.uk is a whole-of-market home energy comparison service. Use the form to see fixed deals available for your property, meter type and region, then compare the details that matter — not just the headline price.
Tip for winter 2026: when comparing fixed deals, focus on the combination of unit rates (p/kWh), standing charges (p/day), contract length, and any exit fees. The “cheapest” tariff on a typical usage profile isn’t always the best fit for your home.
What you’ll need (takes 2 minutes)
- Your postcode
- Fuel type (gas, electricity or dual fuel)
- Meter type (standard/credit, prepayment, or smart meter)
- Approximate usage (or your latest bill, if handy)

What “cheap fixed energy deals” really means for winter 2026
In the UK, the cheapest fixed tariff for winter 2026 isn’t a single national deal. Prices differ by region, payment method, meter type and how much energy your household uses. A deal that looks cheap for a low-usage flat can be poor value for a larger family home with higher gas consumption.
Unit rates (p/kWh)
These determine what you pay for each unit used. For winter, heating usage makes gas unit rates particularly important for dual fuel homes.
Standing charges (p/day)
A daily charge regardless of usage. If you use less energy (or have a second home), a higher standing charge can outweigh lower unit rates.
Tariff terms
Look at contract length, exit fees, payment method rules and whether the tariff is available for your meter (smart/prepay/standard).
Why households choose fixed tariffs for winter
A fixed deal isn’t automatically best for everyone, but it can be the right move if you value predictable bills and want protection against changes in market pricing during peak winter usage.
Budgeting clarity
Fixed unit rates and standing charges make it easier to plan monthly payments during colder months.
Reduced price risk
If prices rise, a fixed tariff can limit your exposure (subject to your tariff terms and fair usage policies).
Clear comparisons
Comparing a fixed deal vs your current tariff is often more straightforward when rates are stable for a set period.
Important: fixed tariff benefits depend on the rates offered and the overall market. If you might need to switch again soon, check for exit fees before committing.

What we show (so you can decide properly)
Quick win: if you have a recent bill, use your kWh usage (not just £/month) for the most accurate winter 2026 comparison.
Fixed vs variable vs standard variable tariffs (SVT)
Choosing the right tariff type is about risk and flexibility. This table summarises the practical differences for a typical UK household heading into winter.
Choosing tip: if you’re considering a fixed tariff purely because you expect a cold winter, also review your home efficiency (thermostat settings, insulation, draft proofing). Reducing usage can deliver savings regardless of tariff type.
Winter 2026 switching checklist (avoid costly surprises)
Before you switch to a fixed tariff, use this checklist. It’s designed for UK households comparing deals during (or ahead of) winter.
- Check your current tariff end date and any exit fees.
- Confirm your meter type (smart, prepayment, economy/TOU) and that the new tariff supports it.
- Use annual kWh if you can; monthly £ amounts can mislead when winter usage spikes.
- Review payment method (direct debit, cash/cheque, prepay) — rates can differ.
- Look for bundled perks only if they don’t inflate the core rates.
- Choose the right term: long enough for stability, not so long you’re locked in.
Common mistakes (and how to avoid them)
Mistake: only comparing estimated monthly cost
Monthly estimates depend on assumptions. Compare the unit rates and standing charges as well, and ensure your usage inputs reflect winter heating patterns.
Mistake: ignoring exit fees
If prices drop or your circumstances change, an exit fee can wipe out savings. Always check the tariff’s fee and conditions.
Mistake: missing meter restrictions
Some tariffs exclude prepayment or certain time-of-use arrangements. Confirm eligibility in your comparison results.

Regional pricing: why your postcode matters
Energy prices in Great Britain vary by region. That’s why a fixed tariff that’s “cheap” in one part of the UK may not be the best value elsewhere. Your comparison should be based on your actual postcode region and meter details.
Network costs
Distribution and regional charges can influence standing charges and overall pricing.
Supplier availability
Not every supplier offers every tariff in every area or for every meter type.
Meter and tariff rules
Prepayment and time-of-use meters may have different pricing structures depending on the region and supplier.
FAQs: cheap fixed energy tariff deals (UK, winter 2026)
Are fixed tariffs always cheaper in winter?
Not always. Fixed tariffs can offer price certainty, but the best option depends on the rates available, your usage, and whether there are exit fees. Comparing whole-of-market options using your postcode is the most reliable way to judge value for winter 2026.
Can I switch if I have a smart meter?
Yes. Many fixed deals support smart meters. Some tariffs are smart-only, while others allow smart or standard meters. Your results will depend on supplier eligibility and your setup.
What about prepayment meters?
You may still be able to find fixed deals, but availability can be more limited. When you compare, select prepayment so you only see tariffs you can actually get.
Will my supply be interrupted when I switch?
No. Switching supplier doesn’t mean your gas or electricity turns off. Your energy continues to flow as normal while the account and billing transfer happens in the background.
Do fixed tariffs have exit fees?
Some do, some don’t. Exit fees are common on longer fixed contracts. Always check the tariff’s terms in your comparison results, especially if you may move home during the fixed term.
How do I know if a deal is truly “cheap” for my home?
Use your annual kWh if possible and compare unit rates + standing charges together. A low unit rate with a high standing charge may not be cheaper overall for low usage households.
