Find the cheapest energy deal for your home right now
A “cheap” energy deal is the tariff with the lowest total annual cost for your household — a blend of unit rates (p/kWh) and standing charges (p/day) across both fuels, set against your usage and distribution region. With the price cap rising to £1,862/yr from 1 July 2026, the deals worth your attention this month are competitive fixed tariffs that let you sidestep that rise.
Enter your postcode and usage and we'll compare a whole-of-market panel for you. If you have a recent bill to hand you'll get the most accurate result, but an estimate is fine to start.
Why now? The cheapest fixed deals currently sit a few percent below the current capped rate. Once the cap steps up on 1 July, the price-capped variable rate becomes the more expensive benchmark — so a fix locked in before then carries its saving through the whole 12 months. See the savings table.
What you'll need (about 2 minutes)
- Your postcode (to identify regional unit rates and standing charges)
- Whether you want electricity only or gas & electricity
- Your current supplier and tariff (if known) — and any exit fee / end date
- Estimated annual usage (kWh) or typical monthly spend

Cheap energy deals compared — June 2026 savings snapshot
The table below illustrates how the main routes compare for a typical dual-fuel home against the incoming £1,862/yr July cap. Figures are typical-use illustrations verified June 2026 — your own result depends on postcode, usage and meter type. Use the comparison form for personalised numbers.
| Route to a cheap deal | Best for | Typical 12-month position vs £1,862 July cap |
|---|---|---|
| Fix now (12-month fixed) | Most households wanting certainty | Best deals sit a few % below today's cap — roughly £300 cheaper over the year than staying variable through the 1 July rise. |
| Stay on the capped variable rate | Those who may move soon / want no commitment | Tracks the cap — steps up to £1,862/yr on 1 July. No exit fee, but no protection from the rise. |
| Smart / time-of-use tariff | EV, heat-pump or battery homes with shiftable load | Off-peak rates from ~7p/kWh (vs ~25p capped) can beat a flat fix — if you shift enough use off-peak. |
| No-standing-charge tariff | Very low users / second homes | Higher unit rate (~30% more) but no daily fee — only wins below ~1,800 kWh/yr electricity use. |
| Solar + SEG export | Homes with (or adding) solar panels | Export pays up to ~32p/kWh on the best SEG tariffs, offsetting the import cap rise. See best SEG export rates. |
Bottom line: for most homes the cheapest route in June 2026 is a competitive 12-month fix locked in before 1 July. If you have shiftable load (EV, heat pump, home battery), a time-of-use tariff can beat it.
How the energy price cap works (and why July 2026 matters)
Ofgem's price cap limits the unit rates and standing charges a supplier can charge on a standard variable tariff — it is not a cap on your total bill, which still depends on how much you use. It is reset quarterly. On 27 May 2026 Ofgem confirmed the next reset: from 1 July 2026 the cap rises +13% to £1,862/yr (+£221) for a typical dual-fuel direct-debit home.
What the cap covers
Maximum p/kWh unit rates and p/day standing charges on default/variable tariffs. Electricity standing charges currently run from ~58p/day (East Midlands) to ~70p/day (Merseyside & N Wales), national typical ~63p/day. Your region sets your exact capped rate.
Why a fix can beat the cap
A fixed tariff sets your rates for the whole term, so it is unaffected by the 1 July step-up. When the cheapest fixes are priced below the current cap, fixing locks in a saving that the capped variable rate loses on 1 July.
It is quarterly, not annual
Because the cap changes every three months, the variable rate is a moving target. A fix removes that uncertainty for 12 months — useful for budgeting through the rest of 2026.
The £1,862 figure is illustrative
It is the typical-use benchmark, not your maximum bill. A high-usage home will pay more; a low user less. That is why comparing on your usage matters more than the headline number.
Fix or stay variable? When fixing wins in June 2026
With the cap stepping up on 1 July, the fix-vs-variable decision is more clear-cut than usual this month. Here is how to read it for your household.
Fixing usually wins if…
- You want budget certainty through the rest of 2026.
- The cheapest fix for your postcode is at or below today's capped rate.
- You're not planning to move home in the next few months.
- You've checked any current exit fee is smaller than the expected saving.
Staying variable can suit if…
- You may move home or change circumstances soon.
- You want zero commitment and no exit fees.
- You expect to switch to a smart / time-of-use tariff shortly.
- You're comfortable riding future quarterly cap changes up or down.
Exit-fee check: if you're already mid-fix, compare any exit fee against the saving from a cheaper deal. If your tariff has ended or is within its switching window, you can usually move with no charge. Related: cheapest standing-charge tariffs.
Smart & time-of-use deals for shiftable load
If you can move usage to off-peak hours — charging an EV overnight, running a heat pump in cheap slots, or storing cheap energy in a home battery — a time-of-use (TOU) tariff can be the cheapest option of all, beating even a good flat fix. The catch: you need a smart meter and enough shiftable load to benefit.
| Tariff type | Off-peak rate | Best suited to |
|---|---|---|
| EV overnight (e.g. Intelligent Octopus Go) | ~7p/kWh (23:30–05:30) | EV drivers charging at home overnight |
| Anytime EV charging (e.g. OVO Charge Anytime) | ~7p/kWh for EV charging | EV homes that can't always charge overnight |
| Heat-pump TOU (e.g. Cosy Octopus) | ~13p/kWh in 3 daily slots | Heat-pump homes (SCOP ~3–4) pre-heating in cheap windows |
| Economy 7 (off-peak night) | ~12.5–14p/kWh (7h night) | Storage heaters / ≥40% of use overnight |
Rule of thumb: a night-rate tariff only beats a flat deal once roughly 40%+ of your usage falls in the cheap window (peak rates are higher to compensate). More detail: best time-of-use tariffs, best EV tariffs and Economy 7 explained.
How to find your cheapest deal (5 steps)
A clear path from “I think I'm overpaying” to a confirmed cheaper tariff — usually done in well under 15 minutes.
- Check what you pay now — unit rates, standing charges, tariff end date and any exit fee from your latest bill.
- Gather your usage — annual kWh for gas and electricity, or your typical monthly spend as an estimate.
- Compare on total annual cost — not the headline rate. Filter by fixed vs variable, payment method and green options.
- Decide fix vs variable vs TOU — for most homes a fix before 1 July; a TOU tariff if you have shiftable load.
- Apply and submit a meter reading — your new supplier handles the transfer with no interruption to supply.
Set a reminder 4–6 weeks before any new fix ends so you can compare again rather than roll onto a standard variable rate. Start now with the comparison form or our compare energy prices tool.
What you'll see in your results
| Tariff detail | Why it matters |
|---|---|
| Unit rate (p/kWh) | Drives cost for higher-usage homes. |
| Standing charge (p/day) | Daily fee regardless of use; matters most for low users. |
| Tariff type | Fixed = certainty vs the 1 July cap rise; variable = flexibility. |
| Contract & exit fees | Weigh any exit fee against the saving before switching. |

Cheap energy deals FAQs (June 2026)
What are the cheapest energy deals in the UK right now?
In June 2026 the cheapest deals are competitive fixed tariffs priced just below the current cap, ahead of the £1,862/yr July rise. The exact best deal depends on your postcode, usage and payment method — compare to see what's available for your address.
Is it cheaper to fix now or stay on a variable tariff?
With the cap rising +13% to £1,862/yr on 1 July 2026, fixing now typically saves a typical home around £300 over 12 months versus staying on the capped variable rate — provided the fix is at or below today's rate and any exit fee is smaller than the saving.
How much is the energy price cap from July 2026?
Ofgem confirmed on 27 May 2026 that the cap rises to £1,862/yr (+13%, +£221) for a typical dual-fuel direct-debit home from 1 July 2026. It's a typical-use benchmark, not a maximum bill.
Will my supply be interrupted when I switch?
No. Switching supplier is administrative — your gas and electricity keep flowing. You'll usually just provide meter readings around the switch date.
Do I need a smart meter to get a cheap deal?
No — a smart meter isn't required for most fixed and variable tariffs. It is needed for smart / time-of-use tariffs (like EV or heat-pump deals), but you can still compare and switch without one.
When is a time-of-use tariff cheaper than a fix?
When you can shift enough usage to off-peak hours — roughly 40%+ of consumption. EV overnight rates around 7p/kWh and heat-pump slots around 13p/kWh can beat a flat fix for homes with an EV, heat pump or home battery.
Can I switch if I'm still in contract?
Usually yes, but you may pay an exit fee. Check your tariff terms and compare the fee against the saving from a cheaper deal. If your fix has ended, you can normally switch with no charge.
How do I know a tariff is genuinely cheaper?
Compare the total estimated annual cost using your own usage — not just the headline unit rate. Check both unit rates and standing charges across gas and electricity, plus contract length and any exit fees.
Are no-standing-charge tariffs cheaper?
Only for very low users. They drop the daily fee but charge around 30% more per unit, so they typically only win below roughly 1,800 kWh/yr of electricity use. See cheapest standing-charge tariffs.
How often should I compare energy deals?
Compare when your fix is nearing its end, after a household change, or when the cap moves — as it does on 1 July 2026. It takes minutes and can highlight a cheaper tariff.
What UK households say
Switching experiences vary by supplier and tariff. These reflect feedback we commonly hear from households using a whole-of-market comparison.
“Locked in a fix before the July cap rise — the comparison showed exactly how much we'd save over the year.”
“Simple form, quick results, and a clear explanation of standing charges versus unit rates.”
“Has an EV, so the time-of-use comparison pointed us to a much cheaper overnight rate.”
