Can I switch to a cheaper single-rate tariff in the UK?
If you’re on Economy 7 (or another multi-rate, time-of-use plan) and you don’t use much electricity overnight, a flat single-rate tariff can be cheaper. With the July 2026 (Q3) price cap setting electricity at 26.11p/kWh and a 57.19p/day standing charge, this is a good moment to check whether your usage still suits a two-rate deal. Compare whole-of-market UK home energy tariffs with EnergyPlus and switch with confidence.

Quick answer
Yes — most UK households can switch to a cheaper single-rate (flat-rate) electricity tariff, and it is usually the better choice unless you genuinely use a large share of your electricity overnight. As a rough rule, if less than about 35–40% of your usage is off-peak, a single rate tends to win because you avoid Economy 7’s inflated day rate.
The benchmark to beat is the July–September 2026 (Q3) Ofgem price cap: electricity 26.11p/kWh with a 57.19p/day standing charge, and gas 7.33p/kWh with a 29.04p/day standing charge (GB direct-debit average, confirmed by Ofgem on 27 May 2026). A good fixed single-rate deal in mid-2026 aims to sit around or just below those unit rates.
To decide, compare the estimated annual cost (unit rate + standing charge + any exit fee) of your current plan against a single-rate quote using your real usage. Run a whole-of-market comparison to see your numbers.
Compare cheaper single-rate tariffs for your home
A single-rate tariff charges one unit rate for electricity all day (plus a daily standing charge). If your home doesn’t shift enough usage overnight, moving from Economy 7 (two-rate) to single-rate is a straightforward way to cut costs — especially now the Economy 7 day rate on many plans sits well above the 26.11p/kWh July 2026 cap level.
Good to know before you switch
- Economy 7 is usually cheaper only if you use roughly 35–40%+ of your electricity off-peak (varies by tariff and region).
- Some meters need a change (or reconfiguration) to move between two-rate and single-rate.
- Always compare unit rate + standing charge + any exit fee — not just the headline unit price.
Use the form to get a tailored comparison. We’ll show whole-of-market options for your postcode and usage pattern, so you can decide whether a cheaper single-rate tariff makes sense.
Tip: If you’re not sure whether you have Economy 7, check your bill for “Day/Night” readings, “Rate 1/Rate 2”, or two different unit prices.
What is a single-rate tariff (and how is it different from Economy 7)?
A single-rate electricity tariff charges the same unit rate (pence per kWh) at any time of day, plus a daily standing charge. It is the most common setup for UK households and the structure the headline price cap is quoted against (26.11p/kWh for July 2026).
Economy 7 (and other multi-rate, time-of-use tariffs such as Economy 10) has two or more unit rates: a cheaper off-peak rate for a set number of hours — typically seven overnight hours for Economy 7 — and a higher day rate for the rest. It works well only if you can shift a large share of usage into the off-peak window.
Quick self-check: are you on Economy 7?
- Your bill shows two readings (e.g. Rate 1 and Rate 2, or Day and Night).
- You have two unit rates for electricity.
- Your home has storage heaters or an immersion heater set to charge overnight.
What you’re really switching
How single-rate tariffs compare to the July 2026 price cap
The Ofgem price cap is set per unit and standing charge, and changes every quarter. For July to September 2026 (Q3), confirmed by Ofgem on 27 May 2026, the GB direct-debit average rates are below. Use these as your benchmark when judging whether a single-rate quote is genuinely cheap.
Why the cap matters for single-rate
The cap caps a standard variable single-rate tariff. Many households out of contract sit on this default. A fixed single-rate deal that lands at or below 26.11p/kWh can give you price certainty and, often, a small saving.
For a typical medium home (~2,700 kWh electricity a year), each 1p/kWh you shave off the unit rate is roughly £27 a year before standing charges — so the unit rate you compare against really matters.
A word on Economy 7 day rates
Economy 7 has its own capped rates, but the day rate is typically higher than the single-rate cap to fund the cheaper night rate. If little of your usage is overnight, you can end up paying that premium for no benefit.
Read our price cap guide for how the cap is built.
Note: the next cap (October–December 2026) is not yet confirmed as of July 2026. The figures above are the current confirmed Q3 cap. Cap changes quarterly, so re-check before any major decision.
When switching to single-rate can save you money
Single-rate isn’t automatically cheaper — it depends on when you use electricity and your meter setup. These are common situations where a cheaper single-rate tariff is a strong fit.
You don’t use much power overnight
If your heating and hot water aren’t set to charge overnight, Economy 7’s higher day rate can outweigh the off-peak discount.
You’ve moved home or changed heating
Swapped from storage heaters to gas or a heat pump, installed a combi boiler, or changed timers? Your usage split may no longer suit a two-rate tariff.
Your day rate looks unusually high
Economy 7 day rates can sit well above the single-rate cap of 26.11p/kWh. If most of your usage is daytime, single-rate often performs better.
You’re on a default/variable plan
If you’re out of contract you’re likely on a standard variable tariff at the cap. Comparing fixed single-rate deals can reveal cheaper, more predictable options.
You want simpler billing
One unit rate makes it easier to estimate costs, track usage, and understand how changes (like a new appliance) affect your bill.
You’re considering an EV or solar
A single-rate can be a sensible base while you assess smart EV tariffs. We’ll help you compare what’s available for your meter and region.
Economy 7 vs single-rate: the simple break-even idea
Whether a cheaper single-rate tariff wins usually comes down to your off-peak percentage. If the Economy 7 day rate is much higher than a single-rate unit price, you need a meaningful chunk of usage to be off-peak to make up the difference.
How to estimate your off-peak share
- Find your last bill and note the kWh for Day and Night (or Rate 1/Rate 2).
- Add them together for total electricity usage.
- Divide night kWh by total kWh to get your off-peak percentage.
Example: Day 2,000 kWh + Night 900 kWh = 2,900 kWh total. Off-peak share = 900 / 2,900 = ~31% — below the rule-of-thumb threshold, so single-rate is likely cheaper here.
Rule of thumb (not a guarantee)
If your off-peak usage is below roughly 35–40%, a single-rate often comes out cheaper. If it’s well above that, Economy 7 may still be worth keeping.
The safest approach is to compare using your postcode and recent usage split. Run a whole-of-market comparison.
What to compare (so you don’t miss the real cost)
Unit rate (p/kWh)
For Economy 7, check both day and night unit rates, not just the off-peak price. Compare the single-rate figure against the 26.11p/kWh July 2026 cap.
Standing charge (p/day)
A low unit rate can be offset by a higher standing charge (cap: 57.19p/day for electricity), especially for low-usage homes.
Exit fees & contract length
If you’re in a fixed deal, check any exit fees and whether switching now is still worthwhile.
Eligibility: can you switch from Economy 7 to a single-rate tariff?
In many cases, yes — but the practical steps depend on your meter and supplier. Here are the main scenarios for UK households.
If you have a smart meter
- Many smart meters can be set up for single-rate or multi-rate depending on configuration.
- Your new supplier may arrange the change as part of the switch (where supported).
- Compare costs carefully: the cheapest option might be a different structure, for example a fixed single-rate plan below the cap.
If you have a traditional Economy 7 meter
- You can usually switch tariff, but moving to single-rate may require a meter exchange or reconfiguration.
- Off-peak hours can vary by region and setup; don’t assume they are always the same seven hours.
- Some suppliers limit tariff availability depending on the meter type.

Total cost: estimated annual cost with standing charge and any fees considered.
Common mistakes when switching to single-rate (and how to avoid them)
Mistake 1: comparing only the unit rate
The standing charge can make a big difference (the cap sets it at 57.19p/day for electricity). Always compare an estimated annual cost using your usage pattern.
Mistake 2: ignoring the Economy 7 day rate
Some households stay on Economy 7 even when most electricity is used during the day. If your off-peak share has dropped, re-check against the single-rate cap.
Mistake 3: not checking for exit fees
If you’re in a fixed contract, an exit fee could reduce or remove savings. Weigh the fee against projected annual savings.
Mistake 4: assuming meter changes are instant
Some switches are tariff-only; others require a meter exchange or reconfiguration. Timeframes vary by supplier and appointment availability.
If you’re unsure, do this first
- Take a photo of your meter display (showing Rate 1/Rate 2 if present).
- Find a recent bill or annual statement for your day/night kWh split.

FAQs: switching to a cheaper single-rate tariff
Is single-rate cheaper than Economy 7 in 2026?
It depends on your usage split. If you don’t use a large share off-peak (below roughly 35–40%), single-rate is usually cheaper because you avoid Economy 7’s higher day rate. The benchmark is the July 2026 cap of 26.11p/kWh.
What is the July 2026 electricity price cap?
For July–September 2026, Ofgem’s cap (GB direct-debit average, confirmed 27 May 2026) is 26.11p/kWh for electricity with a 57.19p/day standing charge, and 7.33p/kWh for gas with a 29.04p/day standing charge.
Will I lose my Economy 7 meter if I switch?
Not always. Some switches are tariff-only. In other cases a supplier may need to reconfigure or replace the meter to support single-rate billing.
Is switching electricity tariffs safe?
Yes. Your electricity supply doesn’t stop during a standard switch. The process is administrative, with meter readings used to close the old account and open the new one.
Do I need a meter change to move to single-rate?
Sometimes. If your meter records separate day and night readings, your supplier may reconfigure or replace it. A smart meter can often support either setup; your supplier confirms what’s needed.
Will switching affect storage heaters or off-peak heating?
Possibly. Storage heaters and some hot water systems are designed to use cheaper off-peak electricity. Moving to single-rate could raise their running cost if you previously relied on night rates — factor this in before switching.
What information do I need to compare accurately?
Your annual electricity usage in kWh (or last 12 months of bills), your current unit rates and standing charge, and — if multi-rate — your day/night split. Accurate inputs improve the savings estimate.
Can I switch gas and electricity together?
Often yes. Many suppliers offer dual fuel. We’ll show what’s available for your home and let you compare single fuel vs dual fuel pricing.
