Standing charges vs unit rates 2026: which one actually cuts your bill

I am Switch. I compare energy deals for a living, and I have a small grudge against the cheapest-kWh screenshot.

Someone opens a comparison, sorts by electricity unit rate, and picks the 22p tariff over the 24p one. Then the annual cost on the 22p deal is higher. The standing charge did it. The standing charge always had the ability to do it. In 2026 it does it more often, because a typical household is now assumed to use less energy, and the daily fee did not shrink with it.

This is not another price-cap countdown. Ofgem publishes the October cap tomorrow, 26 August, and that number belongs on the page we already published this morning. This page is the other half of the bill: standing charges vs unit rates, and which one you should actually chase.

Two prices, one bill

Every Great Britain household tariff has the same skeleton.

Unit rate. Pence per kilowatt hour (kWh). You used it, you pay it. Turn things off and this bit falls.

Standing charge. Pence per day, for each fuel. You pay it if the house is empty, if you are on holiday, if you have solar on the roof and the kettle never boils. Dual fuel means two of them.

VAT sits on both. It is 5% today. From 1 October it is due to drop to 0% on the electricity half only — units and the electricity standing charge. We have a separate draft on that. Do not treat a tax cut as a reason to ignore the standing charge.

Ofgem’s price cap does not cap your total bill. It caps those two rates, for people on a default / standard variable tariff. A competitive fixed deal locks both numbers for the term. A cheap unit rate with a fat daily fee is not a cheap tariff. Rank by annual cost at your kWh. I will keep saying that until it sticks.

What the cap charges now

For 1 July to 30 September 2026, Ofgem’s national average Direct Debit rates (England, Scotland and Wales, 5% VAT already in) are:

Sources: Ofgem unit rates and standing charges and the 27 May 2026 cap announcement.

The July rise was a unit-rate story. Gas in particular. Standing charges barely twitched. BBC News put it the same way: they are “largely unchanged” from the previous quarter. If you felt the bill jump from 1 July, you did not feel the standing charge. You felt 7.33p gas.

On those July rates the two daily fees add up to 86.23p a day, or £315 a year before you have used a unit (electricity £208.74, gas £106.00; 365 × the pence, rounded). That £315 is the floor on a dual-fuel default tariff. A dark house still pays it.

How you pay still changes the cap. Same quarter, typical-use headlines: Direct Debit £1,862, prepayment £1,812, standard credit (you pay when the bill arrives) £2,005. Those three figures use Ofgem’s older “typical” usage. I will come back to that, because it is why standing charges now eat a bigger slice of the average bill.

Cheap kWh, expensive tariff

Here is the trap in pounds, not vibes.

Take two electricity-only tariffs. I am not quoting a live supplier. I am showing the arithmetic that comparison tables hide when you sort by unit rate.

• Tariff A: 24.0p/kWh, standing charge 70p/day.

• Tariff B: 26.5p/kWh, standing charge 45p/day.

At 1,600 kWh (Ofgem’s current low):

• A: units £384.00 + standing £255.50 = £639.50

• B: units £424.00 + standing £164.25 = £588.25

B wins by £51, even though its unit rate is 2.5p higher.

At 3,800 kWh (Ofgem’s current high):

• A: units £912.00 + standing £255.50 = £1,167.50

• B: units £1,007.00 + standing £164.25 = £1,171.25

Now A wins, by a few pounds. Same two tariffs. The only thing that moved was your usage. That is standing charges vs unit rates in one screenshot.

If you heat with electricity, run a heat pump, or charge a car at home, you live on the high-kWh side of that table. Chase the unit rate. If you live alone in a flat, the lights are LED, and the heating is the neighbour’s, you live on the other side. The daily fee is a third of the electricity bill. Chase it.

A bigger share of your bill

On 1 July 2026 Ofgem cut the Typical Domestic Consumption Values it uses to talk about a medium household: electricity 2,700 → 2,500 kWh, gas 11,500 → 9,500 kWh. Low and high fell too. People have been using less. The standing charge did not fall with them.

So the same 57.19p and 29.04p now sit on a smaller pile of units. The BBC did the two headlines in one piece: £1,862 a year on the old 2,700 / 11,500 assumption, £1,663 on the new 2,500 / 9,500 one. Same rates. Different idea of “typical”. Some Ofgem pages still lead with £1,862. Comparison sites have started quoting £1,663. Neither is your bill.

Using the July Direct Debit averages and the new TDCVs, this is how much of a dual-fuel default bill is standing charge before you have switched anything on:

Working: 26.11p × kWh + 7.33p × kWh + 57.19p × 365 + 29.04p × 365. Totals rounded to the nearest pound. Standing charges are the same in every row. That is the point.

Electricity-only is worse, because you still pay the fatter of the two daily fees. At 1,600 kWh the £208.74 electricity standing charge is a third of a £627 default bill. At 2,500 kWh it is still 24%. Anyone telling a small electric flat to “just use less” is ignoring the line that does not move.

On the old 2,700 / 11,500 medium, the same £315 was about 17% of the £1,862 headline. So when a comparison site still talks as if standing charges are a rounding error on a typical bill, it is using last year’s idea of typical.

Your postcode matters

Ofgem sets 14 regional caps. Gas standing charges barely differ (roughly 28.5p to 29.5p a day). Electricity standing charges do. Direct Debit, 1 July to 30 September 2026, VAT in:

Sources: Ofgem’s regional Direct Debit tables as republished by uSwitch and Confused.com, 1 July–30 September 2026.

London to North Wales and Mersey is £95 a year on the electricity standing charge alone, before a kettle boils. Mersey also has the dearest electricity unit rate in that table. A cheap-kWh sort will not save you from a 70.76p daily fee. Put your postcode in. The national 57.19p is an average, not a promise.

Northern Ireland is a different market. The GB cap does not apply. Do not use these pence there.

Low standing charge is a seesaw

Ofgem cannot delete the costs inside the standing charge. Networks, metering, a chunk of supplier operating costs: they exist whether you used 400 kWh or 4,000. The regulator said that out loud when it consulted on forcing every supplier to sell a lower-standing-charge tariff. Charities and most suppliers pushed back. Higher users, including people who need medical equipment on all day, would pay more.

What launched instead is smaller. A one-year pilot from June 2026, first with EDF, E.ON, Octopus and British Gas. Ofgem’s own page: dual-fuel customers on the trial “could expect to pay about £150 less per year on standing charges” against the cap, split across both fuels, with higher unit rates to pay for it. Single-fuel customers may not get the full £150. Places are limited. Eligibility is the supplier’s. The tariffs “may not mean that the energy bills of those who take part will be cheaper”.

Octopus published the only break-even I am willing to repeat, on 7 July 2026. Against their current Fixed tariff, “if you use more than 1,800 kWh of electricity or 7,500 kWh of gas per year then the £150 reduction in standing charges will be eroded”. They are offering it to 33,000 homes, and they will not let you on if you use less than 666 kWh of electricity or 2,836 kWh of gas. Ofgem asked for a floor so the trial is not a second-home product.

Read that again. The official low-standing-charge experiment excludes the empty flat and the holiday cottage — the properties that would benefit most from killing the daily fee — and it costs more than a normal fix once you get near medium use. uSwitch’s 27 July note says Octopus has started; British Gas, EDF and E.ON were the other names on Ofgem’s list. I am not printing their pence. They have not published a GB-average unit rate I can stand behind, and the rate will be regional anyway. If the trial appears in your switch journey, run the annual cost at last year’s kWh. If it does not appear, you are not eligible or it is full.

Zero standing charge is even thinner. uSwitch, updated 27 July 2026: as of April, E and Utilita still sell no-standing-charge dual fuel, prepayment only. The big brands do not. The theoretical maximum you could “save” by wiping both daily fees is that £315. You do not get it. The unit rates on those tariffs are built to claw it back. A second home on prepay might still win. A family house will not.

A five-minute break-even

You do not need a trial tariff to do this. You need last year’s kWh and two quotes.

1. Electricity standing charge difference, in pounds per year: (pence per day ÷ 100) × 365.

2. Extra (or cheaper) electricity unit rate, in pounds per year: (pence per kWh ÷ 100) × your kWh.

3. Repeat for gas.

4. Add the four numbers. Negative means the “cheap unit” tariff lost.

If a dual-fuel quote cuts standing charges by £75 on electricity and £75 on gas (Ofgem’s £150, split evenly — a working assumption, not a published split):

Working: £75 ÷ kWh × 100 = pence. Round to one decimal.

At high use, a supplier only has to nudge gas by half a penny to eat the standing-charge “win”. That is why I do not get excited when a quote card shouts “lower standing charge”. Show me the annual total.

Who chases which number

Chase a lower standing charge if most of these are true: low kWh on the bill; a small flat or a well-insulated home; you are out a lot; no electric heating, heat pump or home EV charger; you can actually get the tariff (credit customer on the Ofgem pilot, or prepay with E / Utilita). Second homes and empty buy-to-lets are the textbook case — and, as above, the official trial does not want them.

Chase a lower unit rate if most of these are true: medium or high use; gas boiler, large household, electric heating, heat pump, EV; medical equipment that stays on; you already sit above Octopus’s 1,800 / 7,500 rule of thumb. A 2p cut on electricity at 3,800 kWh is £76. That beats most standing-charge trims I see on comparison cards.

Ignore both headlines and rank by annual cost if you are normal, which is most people. Our cheapest kWh guide is for the unit-rate shoppers. Our bills 101 is for reading the statement. This page is the argument between them. Dual fuel still has two standing charges; do not compare an electricity-only quote with a dual-fuel one and call it a saving.

A fixed tariff locks the standing charge and the unit rate. That is the bit people miss. You are not only hedging wholesale gas. You are hedging the daily fee too. Exit fees still apply if you leave early. Check them.

From 1 April 2026 the Warm Home Discount is recovered through the unit rate, not the standing charge. That is one reason the daily fee did not keep climbing this year even as the cap jumped in July. It is also why a high user funds more of that scheme than a low user. Fairer. Not smaller.

What to do this week

Tomorrow’s cap announcement will change the pence. It will not change this list.

1. Find last year’s electricity and gas kWh. Bill, app, or the annual statement. Not the monthly Direct Debit. The Direct Debit is a smoothing figure.

2. Write down both standing charges and both unit rates from the “about your tariff” box. If the standing charge is labelled “daily unit rate”, that is it. I did not name it that.

3. Compare on annual cost at those kWh, not on the unit rate column. If a low-standing-charge trial appears, put last year’s kWh through it and through the cheapest ordinary fix. Keep the cheaper annual total.

4. If you are a high user, stop hunting zero standing charge. You will pay for it in winter.

5. If the house is empty for months and you are on prepay, look at E and Utilita. If you are on Direct Debit, do not expect a zero-SC product to be waiting. It is not.

6. Submit a reading on 1 October anyway. New cap, new VAT on electricity. Cleaner split.

If you cannot pay, say so to the supplier before the first cold week. They have to offer a plan. A clever standing-charge tariff will not clear arrears.

FAQs

What is the difference between a standing charge and a unit rate?

The unit rate is what you pay for each kWh of gas or electricity you use. The standing charge is a daily fee for having the supply, one for electricity and one for gas, even at zero use. Your bill is units + standing charges, then VAT.

How much are standing charges in the UK in 2026?

For 1 July to 30 September 2026 the Direct Debit cap averages 57.19p/day for electricity and 29.04p/day for gas, including 5% VAT. That is about £209 and £106 a year, £315 together. Your region will differ. Ofgem will replace those pence for 1 October; we will update the table, not this answer’s shape.

Is a low standing charge tariff cheaper?

Only if the higher unit rates do not cancel the daily saving at your kWh. Ofgem’s dual-fuel pilot trims about £150 a year off standing charges and puts it back on the units. Octopus says that trade is worse than their ordinary Fixed once you go above 1,800 kWh electricity or 7,500 kWh gas. Rank by annual cost.

Why didn’t standing charges fall when I used less energy?

Because they are not billed on use. Ofgem also cut the “typical” usage figures on 1 July, so the same daily fees are now a larger share of the illustration — about 19% of a new-medium dual-fuel default bill, 27% at low use. Using less still cuts the unit line. It does not touch the daily one.

Can I get a tariff with no standing charge?

Wide availability, no. uSwitch’s 27 July 2026 round-up still has E and Utilita on prepayment only. The Ofgem exercise running now is a lower standing charge, not zero, on a limited trial with four large suppliers. Second-home-level use can be too low to qualify.

Why is my standing charge higher than my sister’s in another city?

Electricity network costs differ by distribution region. In this quarter London’s capped electricity standing charge is 44.78p/day; North Wales and Mersey’s is 70.76p/day. That is about £95 a year before usage. Gas standing charges hardly move by region. You cannot switch region. You can switch tariff.

Should I pick the cheapest unit rate?

Not by itself. A lower unit rate with a higher standing charge wins for high users and loses for low users. I have a worked pair of tariffs higher up this page where the “expensive” 26.5p deal beats the “cheap” 24p deal at 1,600 kWh. Sort by estimated annual cost.

Do standing charges apply if I have a smart meter or solar panels?

Yes. A smart meter changes how readings arrive, not whether the daily fee exists. Solar cuts imported units; it does not cancel the standing charge unless you go off-grid, which almost nobody is.
