Economy 7 has been the UK's default cheap-night tariff since the late 1970s. In 2026 the maths has flipped: the Economy 7 day rate now sits above the standard variable cap. The Economy 7 vs SVT 2026 question is no longer "is Economy 7 cheaper" but "is your overnight share high enough" - and for most homes it is not. So is Economy 7 worth it in 2026?
How much is the Economy 7 day rate vs the standard?
Under the Q3 2026 price cap, standard tariffs run 26.11p per kWh flat. The Economy 7 day rate in 2026 sits at 30-34p; night rate around 13.89p. Standing charge is identical at 57.19p/day. Whether Economy 7 cuts your energy costs comes down to one ratio: overnight share. The Economy 7 break even point is around 40%.
Worked example. 2,700 kWh at 30% overnight: 810 kWh × 13.89p + 1,890 kWh × 32p = £717.31. On a single rate tariff: 2,700 × 26.11p = £704.97. Economy 7 costs £12 more. Break-even is around 40% overnight; below it, Economy 7 lifts both electricity bills and total energy bills.
When Economy 7 is still worth it in 2026
- Storage-heated homes. Electric heating charged overnight pushes share above 50%.
- Immersion heater on overnight timer. Two hours nightly shifts 700-1,400 kWh into the cheap window; with washing machines or a dishwasher overnight, clears 40%.
- Heat-pump home, scheduled. Energy efficient heating run overnight; tank and fabric hold warmth into peak periods.
Everyone else - especially gas-heated homes with peak times in the evening - is no longer winning on Economy 7.
Economy 7 alternatives in 2026: the upgrade path
Switching off Economy 7 does not mean switching back to a single rate tariff. The shortlist for the best TOU tariff UK 2026 has on the shelf is two products for non-EV homes and two for EV. The cheapest UK electricity tariff 2026 of any kind sits inside that list - including what most reviewers call the best night time electricity tariff UK households can get.
| Tariff | Night rate | Day rate | Peak (4-7pm) | EV needed |
|---|---|---|---|---|
| SVT | 26.11p | 26.11p | 26.11p | No |
| Economy 7 | ~13.89p | ~30-34p | ~30-34p | No |
| EDF FreePhase Dynamic | ~11.5p | ~19p | ~35p | No |
| Octopus Agile | 5-10p typical | 15-22p typical | Variable, can spike | No |
| Intelligent Octopus Go | 8p (6 flex hrs) | ~26p | ~35p | Yes, verified |
| EDF GoElectric | ~7p (6 hrs) | ~30p | ~30p | Yes, DVLA verified |
Rates as of late May 2026. EV-required tariffs verify ownership via DVLA records or an app-paired charger. FreePhase Dynamic and Agile have no EV requirement and run on a standard SMETS2 smart meter. Standing charge identical across all rows. None of the tariffs offer free energy outside the cheap window.
Do I need an EV for cheap night electricity?
For the two best options, no. The time of use tariff without EV market splits cleanly: EDF FreePhase Dynamic and Octopus Agile are open to any SMETS2 home, no EV needed. EV-only tariffs (Intelligent Octopus Go, EDF GoElectric, British Gas EV Power, E.ON Next Drive) all verify a registered EV - see our EV tariffs comparison.
Is EDF FreePhase worth it? Is Octopus Agile worth it?
EDF FreePhase Dynamic: three fixed bands - Green (11pm-6am, ~11.5p), Amber (6am-4pm, ~19p), Red (4-7pm, ~35p). FreePhase vs Economy 7: amber rate is well below E7's day rate. EDF swaps your meter, with an online account for usage tracking. Full take in our FreePhase review.
Octopus Agile: 48 half-hourly prices per day. Overnight often 5-10p, can turn negative on high-renewable nights (useful for solar panels owners). 4-7pm window capped only at £1/kWh. Agile rewards engagement; FreePhase Dynamic gives you predictable bands you can program against.
Which household type are you?
Gas-heated, no immersion, evening peak times
Below the 40% threshold. Economy 7 is not worth it anymore here - a competitive fix is the simplest exit.
Gas-heated with electric immersion heater
Immersion on a timer pushes overnight share over the line. FreePhase Dynamic beats both Economy 7 and a fix.
Storage-heated, all-electric, no gas
Economy 7 still earns its keep. FreePhase Dynamic is a competitive alternative - worth modelling both at your actual split.
Heat pump or EV at home
Heat pump: FreePhase or Agile. EV: Intelligent Octopus Go or EDF GoElectric (EV tariff comparison).
Should I switch off Economy 7? How to leave it in 2026
You have a two-rate meter showing two registers on each meter reading. Smart tariffs need a SMETS2 meter - request a free upgrade (two to four weeks). Pick FreePhase Dynamic for predictable bands, Agile if engaged, a competitive fix if no shiftable load (SwitchPilot tariff tracker). No exit fees on Economy 7 under cap rules.
SwitchInsights' verdict
For storage-heated and large-immersion homes, Economy 7 is still worth it in 2026. The 40% overnight share is reachable.
For everyone else, leave Economy 7 in 2026. Day rate above the standard cap; smart tariffs do it better, most without an EV. Two routes worth taking: EDF FreePhase Dynamic for predictable bands you can program around, or Octopus Agile if you will read the next day's prices.
The non-EV smart-meter alternative to Economy 7
EDF FreePhase Dynamic gives an 11.5p Green band from 11pm-6am, an amber rate around 19p across most of the day, and a narrow 4-7pm peak - plus around 192 free electricity hours a year flagged by text. No EV needed, no exit fees, 75p/kWh price cap for 12 months.

How SwitchInsights analysed this
SwitchInsights modelled electricity bills at 2,700 kWh across three overnight splits (25/30/40%), weighted by overnight, off-peak and peak rates, scored against the standard variable cap. Refreshes when Ofgem confirms Q4 on 26 August 2026.
Is Economy 7 worth it in 2026: FAQ
Is Economy 7 cheaper than standard tariffs?
Only if more than 40% of consumption falls overnight. Day rates of 30-34p sit above the 26.11p standard variable cap. Storage-heated and large-immersion homes still come out ahead; evening-heavy gas homes lose money.
Is Economy 7 a rip off?
Not a rip off, a legacy structure that has not aged well. The night rate is real, but the day rate is now a penalty. For households without enough shiftable load, the honest verdict is that Economy 7 is not worth it anymore.
Should I switch off Economy 7?
If less than 40% of your electricity falls overnight, yes. Request a SMETS2 upgrade (free), then switch to FreePhase Dynamic or a competitive fix.
FreePhase vs Economy 7 - which wins?
FreePhase Dynamic for most non-EV homes. Amber rate (~19p) is well below Economy 7's day rate (30-34p) and the peak window is narrower (4-7pm only).
What is the cheapest UK electricity tariff in 2026?
Two routes tie at the top. Predictable bands you can program around: EDF FreePhase Dynamic (three fixed time bands, no daily juggling). Engaged: Octopus Agile (overnight regularly under 10p). No shiftable load: a 12-month fix around £1,536/year.
