Fast answer: what’s the cheapest monthly rolling energy tariff?

In the UK, a monthly rolling tariff is almost always a variable tariff whose price tracks the Ofgem price cap. The cap is £1,649/yr for a typical dual-fuel direct-debit home until 30 June 2026, then rises +13% to £1,862/yr from 1 July 2026. So the “cheapest rolling option” for most people is simply the capped variable/SVT rate — but in June 2026 several fixed deals already cost less than the July cap (the cheapest 12-month fix is E.ON Next Fixed v53 at £1,602).

Important: “Monthly rolling” means a variable tariff that continues month-to-month with no fixed term and (usually) no exit fees. Its unit rates can change with the cap — so “cheapest” today may not be cheapest after the 1 July cap rise.

Key takeaways

  • Rolling = variable = cap-tracking: it moves with Ofgem (£1,649 now, £1,862 from 1 July 2026).
  • Compare total cost (unit rates + standing charges), not just one headline rate.
  • Region matters: the same tariff name can cost different amounts across Great Britain.
  • No exit fee = freedom to switch: ideal if you may move or want to jump to a cheaper fix.
  • In June 2026, the best fixes undercut the July cap — so weigh flexibility against price certainty.

Monthly rolling vs fixed: quick rule of thumb

Monthly rolling may suit you if:
You want flexibility, may move soon, want no exit fees, or expect the cap to fall later.
A fixed tariff may suit you if:
You want price certainty through the 1 July rise and can use a deal like E.ON Next v53 (£1,602) that beats the cap.

What you need to know before comparing

  • Your postcode (for regional rates)
  • Whether you have single-rate or Economy 7
  • Whether you’re credit or prepayment
  • Rough annual use (or your last 1–3 bills)

Compare monthly rolling tariffs for your home

Because prices vary by region and meter type, we recommend comparing using your postcode and a couple of household details. We’ll show suitable whole-of-market options — both no-fixed-term rolling tariffs and fixed deals — and highlight key terms (like exit fees and payment method).

Tip: If you’re not sure about your meter type, look at a recent bill: Economy 7 often shows day and night rates. Prepayment will usually be listed as PPM or pay as you go.

How monthly rolling tariffs work (UK)

  • Variable & cap-linked: rolling tariffs track the Ofgem price cap — £1,649/yr for a typical dual-fuel home until 30 June 2026, then £1,862/yr from 1 July 2026.
  • Generally no exit fees: you can usually leave any time without a penalty, which makes switching to a fix (or moving home) easy — but always confirm, as a few products do charge.
  • Not the same as a special “tracker”: a standard rolling/SVT moves with the cap; some suppliers also run separate variable products with different rules.
  • The cap is a unit-rate cap, not a bill cap: what you pay still depends on how much energy you use, plus standing charges.

July 2026 cap rates (typical GB direct debit)

From 1 July 2026 the capped variable rates a rolling tariff will track are roughly:

  • Electricity: 26.11p/kWh unit, 57.19p/day standing charge.
  • Gas: 7.33p/kWh unit, 29.04p/day standing charge.

Electricity is up ~5% and gas ~24% versus the April–June 2026 cap, driven by higher wholesale gas prices. Regional and payment-method variations apply.

Two realistic cost scenarios (illustrative)

These examples show why the “cheapest” monthly rolling tariff depends on standing charge, unit rates and usage. Figures are estimated and not quotes.

Scenario A: Small flat, low usage (single-rate, direct debit)

  • Electricity use: 1,800 kWh/year
  • Gas use: 7,000 kWh/year
  • On the capped rolling rate (from 1 July): roughly £980–£1,050/year depending on region
  • On a cheapest fix (E.ON Next v53 scale): typically a little less, with a fixed unit rate

For lower usage, the standing charge dominates — so a tariff with a lower standing charge often wins, and the saving from a fix is smaller in pounds.

Scenario B: Family home, higher usage (single-rate, direct debit)

  • Electricity use: 3,600 kWh/year
  • Gas use: 14,000 kWh/year
  • On the capped rolling rate (from 1 July): around the £1,862/year typical figure
  • On the cheapest fix (E.ON Next v53 £1,602): potentially £200+/year less than the July cap

For higher usage, unit rates matter more — so a sub-cap fix can save noticeably more than for a low-use home. Weigh that against losing rolling-tariff flexibility.

Assumptions: illustrative single-rate dual fuel at the July 2026 cap; monthly estimate is annual ÷ 12; excludes any one-off credits, warm home discounts, or special schemes. Your actual costs depend on your region, meter type, payment method and exact tariff rates.

Monthly rolling vs fixed deals — June 2026 snapshot

A no-fixed-term rolling tariff stays on the capped variable rate (£1,649/yr now, £1,862/yr from 1 July 2026). In June 2026, every leading fixed deal below undercuts that July cap. The trade-off: a fix locks your unit rates (protecting you through the rise) but may carry an exit fee, while a rolling tariff keeps you free to switch or move.

Tariff (June 2026) Typical dual-fuel/yr Exit fee Notes
Monthly rolling / variable (cap) £1,649 → £1,862 from 1 Jul None Tracks Ofgem cap; full flexibility
E.ON Next Fixed v53 (12m) £1,602 £25/fuel Cheapest 12-month fix
So Energy (18m) £1,612 Varies Longer lock-in
Outfox the Market (18m) £1,624 Varies Online-managed
Octopus 12M Fixed v18 £1,632 £0 Fix the rate, keep the freedom to leave
EDF Essentials Plus (12m) £1,649 £25/fuel Matches current cap level
OVO 2-year Fixed £1,705 Varies Longest certainty

No-exit-fee tip: If you like a rolling tariff’s freedom but want some price protection, Octopus 12M Fixed v18 (£1,632) has a £0 exit fee — you fix the rate yet can still leave at any time, much like a rolling tariff. Prices are typical dual-fuel direct-debit estimates and change frequently; always confirm current rates for your postcode.

Monthly rolling vs fixed vs SVT: what you’re really comparing

A “cheapest monthly rolling tariff” search often mixes three things: a supplier’s monthly rolling variable tariff, a fixed tariff, and the SVT/default tariff. Use this table to keep the comparison fair.

Feature Monthly rolling (variable) Fixed term SVT / default
Price changes Tracks the cap (rises to £1,862 on 1 Jul) Locked for the term Tracks the cap (same as rolling)
Exit fees Typically none Common (e.g. £25/fuel; Octopus £0) None
Who it suits Flexibility seekers; movers; short-term planning Budgeting certainty through the July rise People who haven’t switched; fall-back tariff
What to compare Standing charge + unit rates + terms Same, plus exit fees & end date Same, but options may be limited
Common gotcha Cheapest now, but cost jumps with the 1 Jul cap Fees if you move or switch early Often not the cheapest available

Decision checklist: who monthly rolling suits (and who it doesn’t)

Good fit if you:

  • May move within 3–12 months
  • Want the option to switch quickly if prices change
  • Prefer avoiding exit fees where possible
  • Expect the cap to fall again and don’t want to be locked in

May not suit if you:

  • Need predictable bills through the 1 July cap rise
  • Would worry about price rises mid-year
  • Have a tight budget where stability matters more than flexibility
  • Can take a sub-cap fix like E.ON Next v53 (£1,602)

What to check before you switch

  1. Tariff type: confirm it’s truly monthly rolling/variable and not a fixed tariff.
  2. Exit fees: look for “termination fee” amounts (gas and electricity can be separate).
  3. Payment method: direct debit vs pay on receipt vs prepay can change prices.
  4. Meter compatibility: Economy 7, smart meters, and prepayment have different tariffs.
  5. Discounts/credits: check if they’re conditional (e.g. online-only) or time-limited.
  6. What happens at the 1 July rise: a rolling tariff follows the cap up to £1,862; a fix holds your rate.

Costs, exclusions and common pitfalls (UK)

Monthly rolling tariffs can be straightforward, but these are the areas that most often change which option is “cheapest” for a household.

1) Standing charge vs unit rate

A low unit rate can look appealing, but a high standing charge may cost more overall—especially for low-use homes (small flats, empty properties, second homes).

2) The 1 July cap rise

A rolling tariff that looks cheapest in June will rise with the cap to £1,862/yr on 1 July 2026. If you want to avoid that jump, a sub-cap fix locks today’s rate instead.

3) Economy 7 can flip the result

If you have Economy 7, the cheapest tariff depends on your day/night split. If most usage is daytime, a single-rate tariff may be better (but switching meter type can involve costs and time).

4) “No exit fees” isn’t automatic

Most rolling tariffs have no exit fees, but some products do. Among fixes, Octopus charges £0 while E.ON Next and EDF charge £25/fuel (£50 dual fuel). Always check both fuels.

5) Introductory discounts can distort “cheapest”

Some deals look cheapest because of a time-limited credit or discount. Check whether it applies to your payment method, and what happens after the introductory period.

6) Regional network costs

Energy pricing varies by region (driven partly by local distribution charges). Two neighbours in different regions can see different rates on the same tariff name.

If you rent: you usually have the right to choose your supplier if you pay the bills, but check your tenancy for any process requirements. If bills are included in rent, you may not be able to change supplier.

Good to know: switching is free and takes about 5 working days — you can switch even without a smart meter, and a rolling tariff’s lack of exit fees means you can move to a fix at any time.

FAQs: cheapest monthly rolling energy tariffs (UK)

Is a monthly rolling tariff cheaper than a fixed deal right now?

Not in June 2026. A rolling/variable tariff tracks the cap (£1,649/yr now, £1,862/yr from 1 July), while the best fixes already undercut the July cap — E.ON Next Fixed v53 is £1,602. Rolling wins on flexibility, not price.

Are monthly rolling tariffs always variable?

Yes — a monthly rolling tariff is a variable (month-to-month) tariff that tracks the Ofgem price cap. Always check the tariff information label to confirm how and when prices can change.

Which rolling-style tariff has no exit fee?

Standard rolling/variable tariffs typically have no exit fee. If you want a fixed rate with the same freedom, Octopus 12M Fixed v18 (£1,632) charges a £0 exit fee, so you can leave any time.

What happens to my rolling tariff on 1 July 2026?

Its rates rise with the cap to a typical £1,862/yr (+13%) — electricity ~26.11p/kWh and gas ~7.33p/kWh, plus standing charges. There are no exit fees, so you can switch to a fix beforehand if you prefer certainty.

Can I switch energy if I’m on prepayment?

Often yes, but options may be more limited depending on your meter type and whether you have debt on the meter. If you have arrears, the new supplier may need to agree to take them on under specific rules.

Do I need a smart meter to get a cheap monthly rolling tariff?

Not always. Some tariffs (especially certain smart or time-of-use deals) require a smart meter, while many standard rolling tariffs don’t. Switching is free and possible even without a smart meter.

Can I switch if I’m moving home soon?

Yes, but check timing and any exit fees. If you’re moving in the next few weeks, a rolling tariff without exit fees may be more convenient. You can usually take meter readings on move-out and settle the account.

How long does an energy switch take in Great Britain?

Switching is free and usually takes around 5 working days. Issues like meter details, address matching, or debt can slow it down. Your new supplier will confirm your expected switch date.

Our methodology (plain English)

When we say “cheapest”, we mean the tariff with the lowest estimated total cost for a typical year of usage for your postcode and meter type, based on the tariff’s published charges and eligibility rules at the time of comparison. Cap figures reflect Ofgem’s 27 May 2026 announcement (£1,862/yr from 1 July 2026).

  • We compare: unit rates (p/kWh), standing charges (p/day), payment method pricing, and key tariff terms (e.g. exit fees, smart-meter requirements).
  • We estimate “monthly cost” as estimated annual cost ÷ 12. Your direct debit may be set differently by your supplier.
  • We prioritise like-for-like: electricity-only vs dual fuel, single-rate vs Economy 7, and credit vs prepayment are compared within their category.
  • We flag limitations: some specialised meters/tariffs (multi-rate, heat pump/time-of-use) can require extra checks beyond standard comparisons.

Limitations: Energy prices and tariff availability change. The named fixed-tariff prices are typical dual-fuel direct-debit estimates for June 2026 and move frequently. Always confirm the final rates and terms before completing a switch.
