Economy 7 has been the default cheap-night tariff in the UK since the late 1970s. The proposition was simple: pay a much lower rate for seven hours overnight in exchange for a higher rate during the day. For homes built around storage heating and a hot water cylinder, the maths worked.
In 2026 the maths has flipped for most households. 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 to make the day-rate premium worth it" - and for most homes the answer is no. So is Economy 7 worth it 2026? Below is the working.
The Economy 7 day rate 2026 problem
Under the Q3 2026 price cap, the standard variable tariff is 26.11p per kWh, flat across the day. The Economy 7 day rate 2026 sits at around 30-34p, depending on region and supplier - up to 30% above the SVT. Overnight customers pay around 13.89p.
Whether Economy 7 saves you money comes down to a single ratio: how much of your annual electricity falls in the seven cheap hours. The Economy 7 break even point is the line that ratio has to clear.
Worked example, Q3 2026 rates. A household using 2,700 kWh per year splits 30% overnight (810 kWh) and 70% in the day (1,890 kWh). On Economy 7 that is 810 kWh at 13.89p plus 1,890 kWh at 32p, total £717.31. On SVT it is 2,700 kWh at 26.11p, total £704.97. Economy 7 costs £12 more, despite the cheap night rate.
The break-even point sits around 40% overnight. Anything less and Economy 7 is the more expensive choice.
Published consumption data shows the average UK household runs 25-30% of electricity overnight unless they are actively shifting load. Storage-heated and immersion-heated homes are the exception; most gas-heated homes sit well below the 40% threshold.
When Economy 7 still works in 2026
Three household profiles still earn their keep on Economy 7:
- Storage-heated homes. Storage heaters charge in the cheap window and release heat through the day. Most heating is overnight; overnight share routinely sits above 50%.
- Homes with a large immersion heater on an overnight timer. A 3 kW immersion running two hours every night shifts 700-1,400 kWh per year into the cheap window. Combined with other overnight loads, that often clears the 40% bar.
- Heat-pump homes with overnight scheduling. Same logic as storage heaters but more efficient. The heat pump runs overnight, the building fabric and the hot water tank hold the warmth into the day.
For any household outside those three, Economy 7 is most likely costing more than the standard cap - and a lot more than a modern time-of-use tariff.
Economy 7 alternatives: the upgrade path
Switching off Economy 7 does not have to mean switching back to a flat tariff. The right comparison for any Economy 7 alternatives shortlist is the new generation of smart-meter time-of-use tariffs, which keep the cheap overnight window but drop the day-rate penalty. The best TOU tariff UK 2026 has on the shelf for non-EV homes is one of two products, and for EV homes a different two. The table below covers both.
| 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.
Time of use tariff without EV: which products?
Short answer: for the two best non-EV options, no EV is needed. The time of use tariff without EV market in 2026 splits into two clear products: EDF FreePhase Dynamic and Octopus Agile. Both are open to any household with a SMETS2 smart meter, and neither references EV ownership in its eligibility.
The EV-only tariffs are Intelligent Octopus Go, EDF GoElectric, British Gas EV Power and E.ON Drive. All four verify a registered EV at sign-up. Octopus Go (the non-Intelligent version) lists EV ownership in its terms but does not check - a grey area we would not lean on. The full breakdown lives in our EV tariff UK 2026 comparison for households who do drive electric.
FreePhase Dynamic vs Octopus Agile as a non-EV replacement
FreePhase Dynamic uses three fixed bands: Green (11pm-6am, ~11.5p), Amber (6am-4pm, ~19p), Red (4-7pm, ~35p). The amber rate is the differentiator - it sits well below Economy 7's day rate, so the penalty for using electricity outside the cheap window is much smaller. The full structure is in our EDF FreePhase Dynamic review.
Octopus Agile sets 48 half-hourly prices per day, published the evening before. Overnight often sits at 5-10p and can briefly turn negative on high-renewable nights. The trade-off is the 4-7pm window, which has no rate cap short of £1/kWh on demand spikes. Agile rewards engaged households that check prices; FreePhase suits anyone who wants the tariff to run itself.
Which household type are you?
Gas-heated, no immersion, electricity mostly in the evening
Below the 40% overnight threshold every year. Economy 7 is costing you money against the SVT cap. A competitive fix is the simplest exit.
Gas-heated with an electric immersion heater
Immersion on an overnight timer pushes overnight share over the line. FreePhase Dynamic beats both Economy 7 and a fix here, without active management.
Storage-heated, all-electric, no gas
Economy 7 still earns its keep here. FreePhase Dynamic is now a competitive alternative with a better day rate; worth modelling both at your actual usage split.
Heat pump home, no gas
Heat pumps can be scheduled to do most of their work overnight, storing heat in the fabric and the hot water tank. FreePhase Dynamic or Agile both work; Agile if you will engage with the prices.
EV at home
Intelligent Octopus Go or EDF GoElectric will beat anything else for a household charging an EV nightly. Different article - see our EV tariff comparison.
How to leave Economy 7 2026: step by step
If you are already on Economy 7, you have a two-rate meter. Modern TOU tariffs need a SMETS2 smart meter sending half-hourly data, so the first step to switch off Economy 7 is a meter upgrade.
- Request a SMETS2 upgrade from your supplier. Free under Ofgem rules. Most suppliers fit a SMETS2 within two to four weeks of request, and it replaces the Economy 7 meter.
- Pick your target tariff while you wait. FreePhase Dynamic for set-and-forget, Agile if you will engage with prices, a competitive fix if you have no shiftable load and want certainty. Our SwitchPilot tariff tracker shows current rates against the Q3 cap.
- Switch as soon as the SMETS2 is in. No exit fees on Economy 7 - the tariff sits on your supplier's standard variable structure, which is exit-fee-free under the price cap rules.
SwitchInsights' verdict
For storage-heated homes and homes with a large immersion on overnight charging, Economy 7 is still worth it in 2026. The 40% overnight share is reachable and the cheap window does the work.
For everyone else, Economy 7 is no longer the right answer. The day rate now sits above the standard cap, modern TOU tariffs solve the original problem better, and most of them do not require an EV. EDF FreePhase Dynamic is the default upgrade path; Octopus Agile suits anyone willing to look at prices the night before.
How SwitchInsights analysed this
The SwitchInsights tariff model is weighted across overnight rate, off-peak rate and peak penalty, scored against the standard variable cap. We modelled annual costs at 2,700 kWh of consumption across three overnight splits (25%, 30%, 40%) and compared Economy 7 indicative rates to the Q3 2026 Ofgem cap and current published rates for EDF FreePhase Dynamic, Octopus Agile, Octopus Go, Intelligent Octopus Go and EDF GoElectric. Standing charges held constant at 57.19p/day. The analysis refreshes when Ofgem confirms Q4 on 26 August 2026 or when EDF updates the FreePhase band structure.
Is Economy 7 worth it in 2026: FAQ
Is Economy 7 still worth it in 2026?
For most UK households, no. Under the Q3 2026 cap, Economy 7 day rates of 30-34p sit above the 26.11p SVT. The cheap night rate of 13.89p only covers the day premium if at least 40% of consumption is overnight. Storage-heated and large-immersion homes can still come out ahead; gas-heated homes using electricity mostly in the evening typically lose money on it.
What's the Economy 7 break-even point in 2026?
Around 40% of consumption in the overnight window. For a typical 2,700 kWh household that is 1,080 kWh a year overnight, roughly an immersion running two hours every night. Below that share, Economy 7 costs more than SVT.
Do you need an EV for a time-of-use tariff?
Not for the best non-EV options. EDF FreePhase Dynamic and Octopus Agile have no EV requirement. Intelligent Octopus Go, EDF GoElectric, British Gas EV Power and E.ON Drive all verify EV ownership at sign-up.
What's the best TOU tariff to switch to from Economy 7?
For non-EV homes with shiftable loads, EDF FreePhase Dynamic is the default upgrade: green band ~11.5p, amber ~19p, red ~35p. Octopus Agile suits engaged households reading the next day's prices. For EV homes, Intelligent Octopus Go or EDF GoElectric give the lowest overnight rates at 7-8p.
When should I leave Economy 7?
If less than 40% of your electricity falls overnight, Economy 7 is costing you money. Request a SMETS2 smart meter upgrade (free), then switch to FreePhase Dynamic or a competitive fix depending on whether you have shiftable load.
How do I know if I have an Economy 7 meter?
Economy 7 meters show two registers (Rate 1 and Rate 2, or Normal and Low) and your bill lists two unit rates. A SMETS2 upgrade replaces it and unlocks any modern TOU tariff.
Is FreePhase Dynamic better than Economy 7 for a non-EV home?
For most non-EV homes, yes. FreePhase's amber rate (~19p) is well below Economy 7's day rate (30-34p), and the peak window is narrower (4-7pm only). The slightly higher overnight green rate of ~11.5p is more than offset by the day-rate advantage.
