The best electricity meters, compared.
Top pick: Jadeshay DIN-rail energy meter Best value: DEWIN DIN-rail kWh meter – About £13.29 and 4.1 from 253 reviews for a wired single-phase check. Not the second-highest score, and MID is not stated. Updated October 2026.
An electricity meter you buy for a home check shows kilowatt-hours for one appliance, one circuit, or one cable. It is not the settlement meter your supplier or the network already owns. In the UK the usual shapes are a BS 1363 plug-in monitor, a DIN-rail module, and a clamp around one live conductor. The [electricity meter buying guide](/hub/measuring-equipment/electricity-meter/sub/electricity-meter-buying-guide) separates those jobs. A suitable meter matches the job and the UK limits. A plug should store a unit rate if you want a cost, and the current limit should respect 13 A. An alarm at 3680 W is a 16 A figure, not a UK socket rating. A rail meter should print a basic and a maximum current. A clamp should state an opening that closes on the cable. Wi-Fi monitors of this type need 2.4 GHz. A class on a listing is a manufacturer claim, not approval to charge someone else. Own use is a check. Charging a tenant is trade and needs an approved design, fitted in an approved way.

Personal buying guide
Question 1 of 2
Can you unplug the load from a UK socket?
The Jadeshay DX-220V is a DIN-rail LCD with 5(32) A on the title and a backlit 6+1 digit total, at £13.69. Across 5 amazon.co.uk reviews the line is 4.8, and only two written texts are saved, both from the United Kingdom. One owner used it beside a granny EV charger and said you need spare consumer-unit space or a separate IP-rated DIN box with a window. That reviewer could not say whether this meter or the charger display was the more accurate. The second text says it works well if you read the instructions. The title says 50/60 Hz and one bullet says 50 Hz. No class index and no MID line are on the listing. A 4.8 from five reviews does not outrank a meter with a much larger rating file.
Pros
Cons
Best for: A modest single-phase circuit already inside 32 A, with an electrician and somewhere to see the screen.
Less suitable: An annex supply above that current, a billing charge, or a choice based on the star line alone.
Specifications
Common questions
What current is on the title?
5(32) A. The title says 50/60 Hz. One bullet says a rated frequency of 50 Hz.
What did the UK reviews say about fitting?
Two UK reviews are in the review notes. One says you need space in the consumer unit or a separate IP-rated DIN box with a window, and could not say which reading was more accurate beside a granny EV charger.
Is MID stated?
No. The bullets claim an intelligent chip and do not give a class index.
The Emporia Vue 3, model EMV3A-3P-16, is a hard-wired monitor with sixteen 50 A branch sensors and three 200 A clamps, at £199.99. Across 78 amazon.co.uk reviews the line is 4.6. Only three United Kingdom texts are in the review notes, and each says an electrician’s install worked, with one of them flashing ESPHome for Home Assistant on a single-phase board. The listing asks for 2.4 GHz Wi-Fi, claims sensors accurate from ±2%, names solar and net metering, says no Delta, and says an extra 200 A sensor is sold separately for some systems. One-second data stays only while the app is open. Non-UK reviews in the same notes call the clamps bulky in a crowded board, so the wide circuit count still depends on a competent fit and on space, and three UK texts do not turn the ±2% line into a test we ran.
Pros
Cons
Best for: You want many branch circuits on one app and an electrician will fit the sensors.
Less suitable: One kettle, a billing nameplate, or a board with no room for the clamps.
Specifications
Common questions
Is this a plug-in monitor?
The power description says Hardwire. The three UK reviews in the review notes say an electrician fitted it in the consumer unit.
Which Wi-Fi does the listing need?
2.4 GHz Wi-Fi and an internet connection. The app is named for iPhone, Android, and the web.
How many sensors does this style include?
Sixteen 50 A branch sensors and three 200 A clamps. The listing says an extra 200 A sensor is sold separately for some systems, and it says no Delta.
The Awootsv PM04UK-1 sits in a UK socket and shows voltage, watts, kilowatt-hours, and a cost once you store a unit price, at £11.99. Across 86 amazon.co.uk reviews the line is 4.5, and 26 of the saved texts are from the United Kingdom. Reviewers use it on heaters, a television, a computer, and a washing machine, and several say the figure looks right for that comparison. The listing says it alarms and disconnects the plug above 13 A, and it also says there is no backlight, which matches reviews that struggle to read it at night. The reset is hard to reach, the plugs can feel tight, and one UK review says the cost figure is in euros only. One unit flashed orange and died when a laptop charger was switched on, and another was returned because it would not work. It is the top pick in this set for one appliance you can unplug, with that euro display and the missing backlight as the limits.
Pros
Cons
Best for: You want the cost of one plug-in appliance and you will type in your own unit rate.
Less suitable: A shower, a cooker, a hard-wired charger, or a charge you will send to someone else.
Specifications
Common questions
Does the listing include a backlight?
The bullets say there is no backlight. UK reviews also say the screen is hard to read at night.
What does the listing say happens above 13 A?
It says the monitor alarms and disconnects the plug when the load exceeds 13 A.
Does it need a battery?
Batteries included and batteries required both say No. One UK review says the screen stays blank until the unit is plugged in.
The KETOTEK KTEM03 puts a backlit LCD on a 2.9 m lead so you can read a fridge or a workshop heater without kneeling at the socket, at £25.99. Across 6 amazon.co.uk reviews the line is 4.4, and five of the saved texts are from the United Kingdom. Those reviews like the separate screen for standby loads and for minimum and maximum power. The listing sets the overload at 3680 W, which is a 16 A figure, and it does not state 13 A. One UK review says the timer runs 17 to 18 minutes long over a real day, so that reviewer would not treat the clock as the length of the test. The listing says a CR2032 is included and also says batteries are not required. It is a plug with a screen you can place on a bench if you time the run on your own clock and you keep the load inside a UK 13 A socket.
Pros
Cons
Best for: You need the screen away from a tight socket and you will time the run yourself.
Less suitable: A whole-house total, a tenant bill, or a continuous load near 3680 W on a BS 1363 socket.
Specifications
Common questions
How is the display arranged?
The LCD is separate from the plug and joins it with a 2.9 m cable. The listing says the backlight lasts 10 minutes and can be turned off.
What overload figure does the listing use?
3680 W, adjustable from 0 to 3680 W. The listing does not state a 13 A rating.
What did UK reviews say about the clock?
One of five UK reviews says the timer runs 17 to 18 minutes long over 24 hours. The other four do not name a fault.
The DEWIN KWS-AC301 is a panel meter for 0–100 A and 50–300 V, with a closed current transformer and a temperature sensor in the title, at £16.39. Across 26 amazon.co.uk reviews the line is 4.3, and two of the saved texts are from the United Kingdom. Those two say it works and is fairly accurate, and one used it on solar-battery backup power. The same UK note says the colour LED is dim indoors and has no brightness control. The other UK review says the instructions are vague on how to wire the current sensor. The listing limits the supply to pure AC at 50–63 Hz and says a square-wave or repaired sine-wave inverter output will damage it. EN 61010-1 is stated and MID is not, so this stays a wired display for one pure-AC circuit.
Pros
Cons
Best for: A pure-AC panel where you can thread the closed transformer and you can live with a dim LED.
Less suitable: A UK socket, a modified-sine inverter output, or a tenant bill.
Specifications
Common questions
Is the transformer a split clamp?
The title says a closed-type transformer, plus a temperature sensor.
What supply does the listing allow?
Pure AC, 50–63 Hz, 50–300 V, 0–100 A. It says the device will be damaged on a square-wave inverter or a repaired sine wave.
What did UK reviews say about the screen?
One of two UK reviews says it works and is fairly accurate, but the display is dim. The other says the instructions are vague on how to wire the current sensor.
The Emlite listing titles an ECA2-MID single-phase meter at 100 A direct connection, at £54.45, and the bullets say it is fully MID approved and measures import active energy. Across 37 amazon.co.uk reviews the line is 4.2, from five United Kingdom texts. One reviewer who has used the make more than once says it performs well. Another calls it a good replacement after an electrician fitted it in place of the house meter, which is a review claim and not a job to copy. Two of the five texts say there is no wire lead seal, and no instructions or safety data. Voltage and mounting are not stated on the listing. The words on the Amazon page are not a photograph of the metrology mark, the year, and the approved-body number on the meter you receive.
Pros
Cons
Best for: You are comparing a 100 A import meter whose listing claims MID, and you will check the marks on the metal before any recharge.
Less suitable: Replacing the supplier meter yourself, or treating this row as a finished tenant bill.
Specifications
Common questions
What approval does the listing claim?
The bullets say fully MID approved, and that it measures import active energy.
What current is in the title?
100 A direct connection, single phase. The title includes ECA2-MID. Voltage and mounting are not stated on the listing.
What did UK reviews say was missing?
One of five UK reviews says there is no wire lead seal. Another says there are no instructions or safety data.
The DEWIN AK3-AT1-GL-M-X clips to a 35 mm DIN rail and the title prints 220 V and 5(80) A, at £13.29. Across 253 amazon.co.uk reviews the line is 4.1. In the first 50 texts, nine are from the United Kingdom. Those UK notes say it snaps on, shows voltage, current, watts, and watt-hours, and one owner used it to indicate EV charging energy. The same UK reviews say the terminals are small, one housing melted on a 4 kW heater after just over 1000 kW, and one LCD burst within a year. MID is not stated; the listing cites GB/T17245.321-2008. It is the best value in this set for a cheap wired check of one circuit if an electrician fits it and you accept that melt report, and the page does not show a billing approval.
Pros
Cons
Best for: An electrician is fitting a check meter on one single-phase circuit and you want the large review file at this price.
Less suitable: Opening a consumer unit yourself, recharging a tenant, or leaving a load near 80 A without a competent check.
Specifications
Common questions
What current does the title state?
220 V and 5(80) A, single phase, two-wire, on a 35 mm DIN rail.
Does the listing say it is MID approved?
MID is not stated. The listing cites GB/T17245.321-2008.
What did UK reviews say about reliability?
One says the terminals are small. One says the housing melted on a 4 kW heater after just over 1000 kW. One says the LCD burst within a year.
The POFET CP025107 is an 80 A Wi-Fi clamp on a 10 mm opening, powered from 110–240 V, at £16.99, using Tuya or Smart Life on 2.4 GHz only. Across 380 amazon.co.uk reviews the line is 3.8, and 34 of the first 50 texts are from the United Kingdom. One reviewer matched a day at 18.9 kWh on the supplier meter and 19.2 kWh in the app. Several others say the clamp will not close on standard UK tails and can under-read if it does not fully close. The listing says one direction only, so solar export sits outside that claim unless the page says otherwise. UK reviews also say the app has no unit price, that hourly history can be missing, and that you must add flex because the terminals are live. One buyer reports four failures from four devices. It is a remote check of one cable the clamp can actually shut around.
Pros
Cons
Best for: One live conductor the 10 mm clamp can close on, a 2.4 GHz network, and a competent person to wire the supply.
Less suitable: Standard UK meter tails, a tariff inside the app, or a bidirectional solar feed.
Specifications
Common questions
Will the clamp fit a UK meter tail?
The listing says the opening is 10 mm and will not fit larger main cables. Several UK reviews say it does not close on standard tails.
Does the listing cover solar export?
It says measurement is one direction only, and that bidirectional solar or battery measurement is not supported unless otherwise specified.
Which app and Wi-Fi does it use?
Tuya Smart or Smart Life, on 2.4 GHz only. It must be wired to 110–240 V. It is not a battery clamp.
The CYTGOUPER XTM75S-U is a 35 mm DIN-rail meter with 20(80) A and a 5+1 digit LCD on the listing, at £16.09. Across 4 amazon.co.uk reviews the line is 3.3, and two UK texts are saved. One calls it well made for a secondary meter on an annex, outhouse, or garage, and says to treat it as 80 A rather than 100 A. The other describes blanked upper terminals, says there is no calibration, and had not yet run the EV load. That second review also calls the meter mechanical, which does not match the LCD wording. A pulse output is stated, and MID is not. The title says both 2-wire and 4P. Four reviews cannot carry an annex bill or an untested charger circuit.
Pros
Cons
Best for: You already know you need about 80 A on one secondary circuit and an electrician will confirm the terminals.
Less suitable: A 100 A house supply, a tenant charge, or a buy based on four reviews.
Specifications
Common questions
What current is on the title?
20(80) A. A UK review says to treat it as an 80 A meter, not a 100 A meter.
Is the display an LCD?
The listing says a 5+1 digit LCD with a blue backlight. One of the two UK reviews calls the meter mechanical.
Does the listing say you can calibrate it?
No class index and no MID line. One UK review says there is no calibration, and that reviewer had not yet run the EV load.
Nine electricity-meter listings on amazon.co.uk were scored from the UK listing and the review notes already saved with each row, not from a laboratory test. Amazon stars, review volume, and fit to a UK check are weighted 41, 29 and 30. The shelf price is not in the score. It decides the best-value award only. Deductions apply for a short review count, a melted housing or a failed display, a unit that died, a clamp that UK reviews say will not close on standard tails, a plug whose only overload figure is 3680 W, conflicting lines on the same listing, a cost figure a UK review read as euros, a clock that gains many minutes a day, a star line with few United Kingdom texts, and a billing-shaped listing with no seal and no instructions in the UK texts. A stated class, a MID sentence, or a safe continuous load is not proved by the score.
Amazon stars
41%Up to 41 points from the amazon.co.uk star average. The line is the UK listing. It is not a laboratory score, and it does not prove a class index or a MID mark.
Review volume
29%Up to 29 points from how many reviews sit behind that star line, with a cap so a huge file cannot swamp the other checks. Fewer than 20 reviews, and fewer than six, draw separate deductions. A large file whose saved sample is mostly outside the United Kingdom is also marked down.
Fit to a UK check
30%Up to 30 points for the job on the listing, whether you can read kilowatt-hours and a unit price, and how you connect it. A plug that states a 13 A disconnect scores higher on access than a hard-wired module. A 3680 W-only overload is not treated as a UK socket rating. An app with no unit price in the UK reviews scores lower than a local screen with a stored tariff.
Start with the job, then whether the reading will charge someone else, then the UK current limit and the register. The notes below follow that order. None of the scores is a laboratory test.
An electricity meter in this comparison is either a check meter you buy to see kilowatt-hours, or the settlement meter your supplier or the network already owns. On amazon.co.uk the useful buy is a BS 1363 plug-in monitor for one appliance, a DIN-rail kilowatt-hour module for one circuit, or a CT clamp for a cable or a board. Quality is the match to the job. A plug monitor is not a settlement meter, and none of these scores is a laboratory test.
BS 1363 is a 13 A system. A 3680 W alarm is a 16 A figure. Do not load a UK plug toward that number, and do not treat the alarm as a safe continuous rating.
A plug-in monitor sees one appliance. It cannot see a shower, a cooker, or a hard-wired charger, and it is not the settlement meter your supplier or the network owns.
Citizens Advice says moving a gas or electricity meter yourself is illegal. In Great Britain phone the supplier. In Northern Ireland meter replacement is NIE Networks. Do not open a consumer unit unless you are competent.
The job picks the meter. One plug-in appliance, one fixed circuit, many circuits, or a charge to another person. Stars do not pick the type. A plug-in monitor sits between a UK socket and one appliance and cannot see a shower, a cooker, or a hard-wired charger. A DIN-rail meter clips to a 35 mm rail and counts one wired circuit. A clamp monitor goes around one live conductor and often needs its own mains supply. Own information is a check meter.
BS 1363 is a 13 A system. A 3680 W alarm is a 16 A figure, not a UK socket rating. Do not load a plug toward that number. The clamp opening has to match the cable. Reviews of one Wi-Fi clamp in this set say a 10 mm jaw will not close on standard meter tails. Wi-Fi monitors here need 2.4 GHz. You want kilowatt-hours on the register, and pence per kilowatt-hour if you want a cost. Import-only meters miss solar export. A one-direction clamp on a solar feed will not show export.
Three typical situations, each with a recommendation from this comparison.
You want the cost of a heater, a television, or another appliance you can unplug, and you will type in your own unit rate. The Awootsv plug-in monitor is about £11.99, with 4.5 from 86 reviews, and the listing says it disconnects above 13 A. There is no backlight.
You need a circuit total for an annex, a heat pump, or an EV lead, and an electrician will fit the meter. The DEWIN DIN-rail meter is about £13.29, with 4.1 from 253 reviews, and the title prints 5(80) A. MID is not stated, and one UK review describes a melted housing.
You will charge a tenant, a let, or a workplace, so a check meter is the wrong tool. The Emlite listing says it is fully MID approved, at about £54.45, with 4.2 from 37 reviews, for 100 A import energy. The Amazon sentence is not the nameplate. Check the marks on the meter before any recharge.
In this set the top pick is the Awootsv plug-in monitor at about £11.99. It is the highest score, for one BS 1363 appliance when you want kilowatt-hours and a stored unit price, and the listing states a 13 A alarm and disconnect. There is no backlight. One UK review says the cost was in euros. The best value is the DEWIN DIN-rail meter at about £13.29, with 4.1 from 253 reviews. That award is the low price for a wired single-phase check with a large review count. It is not the second-highest score. The Emporia Vue 3 scores higher at about £199.99. The DIN meter is not the top pick because a UK review describes a melted housing on a 4 kW heater and an LCD that burst within a year. MID is not stated on that listing. No laboratory test was run.
DEWIN DIN-rail kWh meter
About £13.29 and 4.1 from 253 reviews for a wired single-phase check. Not the second-highest score, and MID is not stated.
