3.13 million "smart" meters that are not smart. Check your bill before you pay more from October 1

After almost a decade of the smart meter program, millions of British homes are still receiving estimated bills. New government data, Citizens Advice warning and a 4% price cap increase. — what does this mean for Polish families in London and the west of the capital.

Smart meters were supposed to end manual reading and give people control over their electricity and gas consumption. After almost a decade of the program, government statistics tell a different story: at the end of June 2026, around 3.13 million smart meters in the UK were operating in traditional mode - traditional mode or dumb mode in English.

These are not meters that "work a little worse". In this mode, the device still counts consumption, but does not automatically send the reading to the supplier. The company will then bill you based on the estimate. With rising energy prices, the estimate can easily turn into an overpayment or - after many months of silence - into a shocking equalization bill.

Which is confirmed by official data
The Department for Energy Security and Net Zero published on August 27, 2026 a quarterly report on the status of the program at the end of June. Independent tallies based on detailed DESNZ tables indicate approximately 3.133 million smart meters in traditional mode. At the end of March, it was approximately 3.01–3.06 million. So the problem is not decreasing - it is slightly increasing.

The scale of installation itself looks better: there are already over 41 million smart and advanced meters in the UK, and approximately 92 percent of them work in smart mode. However, this does not console the 3 million households that formally "have a smart meter" and see the letter E for estimated on the invoice.

Citizens Advice responded on the same day. Gillian Cooper, Director of Energy, put it bluntly:

"Smart meters are supposed to help track usage and reduce bills. Today's figures show three million of them don't. When the meter fails, the customer pays the price - with months of inaccurate, estimated invoices."

The organization's own examination is even more rigorous than the government's statistics:

36 percent people with a smart metro - about 6.7 million households - regularly provide readings themselves, by 20 percent more than a year earlier;
1.2 million households do not receive the exact bills they expected after meter installation;
in 2026, the problem with the smart metro was the most common reason for complaints to energy suppliers.

Which? in August 2026 reported that 31 percent of its smart metro members have had some sort of problem with the device in the last 12 months. The most common problems were the IHD display (the small screen on the tabletop) and the lack of automatic reading.

Why does it hurt right now
On August 26, Ofgem announced that from October 1, 2026, the energy price cap will increase by 4%. For a typical gas and electricity home paying Direct Debit, that's an average of around £60 more a year - up from £1,663 to £1,723 if this level were maintained for 12 months.

The growth is mainly driven by wholesale gas prices. The gas bill goes up by about 8 percent, houses without gas will experience less than 1 percent. About 11 million households on a fixed tariff will not see this increase - the rest, on a variable tariff, will.

This is the worst time for a supplier to count on "by eye". Last winter's estimate with higher October rates can inflate down payments. In turn, too low an estimate ends with one large invoice when the meter finally "comes to life" or someone sends a manual reading.

What is "dumb mode" and where does it come from?
Smart meter in dumb mode:

still measures consumption on site;
does not communicate automatically with the supplier;
does not update the app or In-Home Display as it should;
forces the customer to enter readings manually if they want to pay for actual consumption.

Most common causes:

SMETS1 after changing supplier. The first generation of meters (installations before spring 2019) often lost connection to the switch. Some were "migrated" connected to the DCC network, but not all.

No WAN coverage - weak signal in the apartment building, basement, or on the outskirts.

The counter is installed but not running in the supplier's system.

Replacement and faults. In the second quarter of 2026, large suppliers performed approximately 1.1 million assembly works. Of this, approximately 570 thousand are replacements of existing devices, and 525 thousand new installations. Exchanges therefore accounted for more than half of the traffic - earlier this year it was closer to 30%. This is a signal that more and more "new" visits are a repair of what was supposed to work.

Important: the counter in dumb mode does not lie by itself. Still records consumption. The problem is with communication and invoicing. That's why manual readings work - and are worth sending.

How to check in 2 minutes if your counter is really working
You do not need to know the SMETS1 or SMETS2 model. All you need is a recent bill or supplier's application.

Open your latest electricity and gas invoice.

When reading, look for the "smart" marking or the letter "S". This means the reading came automatically.

If you see the letter "E" or the word "estimated" - the provider did not get an actual reading.

Compare with the application. If the application has been showing the same thing for weeks or asking for a manual reading, the meter is almost certainly not working in smart mode.

Take a look at the In-Home Display (small screen). No update, no connection message, or a "new message" that no one reads is another sign.

If you are unsure, call your supplier and ask directly: "Is my meter operating in smart mode?" Ask for confirmation in writing (email or note in your account).

What to do if the counter is "dumb"
Send your reading manually - today. Electricity and gas separately. Take a photo of the counter with the date. This is the fastest way to stop paying respect before the October increase.

Report the fault to the supplier in writing (app, e-mail, chat). From February 23, 2026, the supplier has 5 business days to tell us how he will solve the problem. If they don't do this, you'll be entitled to £40 compensation for each step left unfinished - this is Ofgem's new standard.

Watch for 90 days. From May 2026, suppliers must take all reasonable steps to restore the meter to smart mode within 90 days of becoming aware of the failure.

Don't wait for it to "fix itself." Citizens Advice highlights that suppliers and network operator DCC often blame one another. The customer stays with respect.

Complaint. If the supplier does not respond: formal complaint to the company, then the Energy Ombudsman. Citizens Advice Consumer Service helps you free of charge - also by telephone.

What a smart meter won't do - even when it works
A working smart meter does not reduce the kWh rate. It only gives you an accurate bill and a preview of your consumption. Savings only appear when you really change your habits or switch to a time-of-use tariff, a heat pump, or an EV charger. For this you need a meter in smart mode. Therefore, a "dead" smart meter is not just an annoyance - it is a cut-off from cheaper tariffs that are expected to become more widespread with Market-wide Half-Hourly Settlement.

For families on Universal Credit and in council housing
In Ealing, Southall, Northolt and across west London, many Polish families are on variable tariffs and estimates. With UC, Carer's Allowance and fixed care costs, any inflated Direct Debit hurts twice as much.

A few rules of thumb:

Don't blindly agree to increase the down payment "because of winter". Send the reading first.

If the supplier threatens debt collection based on the estimate - demand settlement based on the actual meter reading.

In a council flat or from a landlord: the meter is usually owned by the tenant, but access to the cabinet can be a problem. Take a photo, send the reading, save the receipt.

Prepayment/key: separate story. If you can't top up via the app or IHD, it's a failure - report it immediately.

Short verdict
The smart meter program is not a “scam.” Most of the more than 40 million devices work. But three million in dumb mode after a decade of implementation is not a marketing failure - it is a system in which the customer continues to do the job that the counter was supposed to do.

Before October 1, do three things: check the letter on the invoice, send a reading, report the defect in writing. That's 15 minutes that can save you from months of paying for air or one big bill in November.
