The best timer switches, compared.
Top pick: Status IONOS 24 Hour Plug-in Timer Switch Best value: Status IONOS 24 Hour Plug-in Timer Switch – About £4.95 for a 15-minute mechanical dial, 4.5 from 87 reviews. Score 90, mapped from the star line. No amp or watt rating is stated, and at least two reviews say the timer did not work. Updated October 2026.
A timer switch turns a mains load on and off to a programme. In the UK you buy one for a lamp, a fan, holiday lights, an aquarium, or a hot-water cylinder. Most fit a BS 1363 socket. Some are wired segment timers for an immersion. A countdown switch is for a light that should go off after a few minutes. The first split is plug-in versus wired. You recognise a suitable timer switch by a UK plug, a stated current matched to the appliance, and a programme you can set. A portable appliance needs one plug-in whose stated maximum covers that load. A wired immersion needs a timer in the 16 A class. Mechanical dials repeat one day and lose the time after a power cut. Digital plug-ins add a weekly programme and a random offset. The [timer switch buying guide](/hub/electrical-equipment/timer-switch/sub/timer-switch-buying-guide) sets out type and load. Plug-in timers have to suit BS 1363 under the Electrical Equipment (Safety) Regulations 2016. If the body or the plug is hot, cracked, or smelling, stop using it.

Personal buying guide
Question 1 of 2
How will it connect?
The Status IONOS, model ION24HT10, is £4.95, marked best value in this set, with 4.5 from 87 reviews and 15-minute segments on a mechanical dial that the bullets say needs no batteries. It is the low first spend for a lamp that repeats every day, and reviewers call it understandable for an older user who does not want a menu. Two UK reviews say the box has no setup sheet, only headings on the outside, and at least two reviews say the timer did not work. One buyer is going back to an electronic timer because mechanical units have not lasted for them. The saved bullets still do not state amps or watts, so a heater figure cannot be checked against this page. The catalogue weight of 30 g and a 5 × 5 × 20 cm side look implausible next to the mini’s 120 g, and they are left as printed. Rank 1 in Timers is shared with the mini on the capture and is not a durability test.
Pros
Cons
Best for: You want a cheap single mechanical timer for a repeating lamp, and you will test it the day it arrives.
Less suitable: You need a stated wattage, instructions in the box, or evidence from thousands of reviews.
Specifications
Common questions
What load is this Status timer rated for?
The saved bullets do not state amps or watts. Do not assume 13 A or 3120 W.
Does it need batteries?
The bullets say the mechanism is mechanical and needs no batteries. The listing does not claim a backup battery.
Are there instructions?
Two UK reviews say the box has no setup sheet, only headings on the outside.
The LIDER countdown switch, model ULT-CT-G-30MW, is £19.99 and 4.5 from 27 reviews, with buttons for 1, 5, 10, 15, 20 and 30 minutes plus a long-press hold-on. It is a fixed white plate, 86 × 39 × 86 mm, for a run-on light, not a 24-hour programme. Reviewers use it on a garage light and a hallway, call the 30-minute step useful for a bathroom light, and one replaced a troublesome occupancy sensor. The listing says earth is required and neutral is not required, while one reviewer says the sheet seemed to treat earth as if it could stand in for neutral, and rejects that reading. Rear screw terminals are called hit and miss on lighting conductors, and instructions are called lacking, with no customer support in one review. The highlight line that says plug-in conflicts with the wiring text, so this row is a wired switch. Stated loads split by lamp type: incandescent or halogen to 1000 W, LED or CFL to 300 W, resistive to 10 A, and motors to 1/6 HP.
Pros
Cons
Best for: You want a wired countdown of up to 30 minutes for a light or a small fan, fitted by someone competent.
Less suitable: You wanted a plug-in 24-hour programme, or you are not sure how the earth and neutral should be connected.
Specifications
Common questions
Does this countdown switch need a neutral?
The listing says earth is required and neutral is not required. One review disputes an instruction that appeared to use the earth as a neutral. Follow a competent install, not a conflicting sheet.
Is it a plug-in timer?
The title and the wiring bullets describe a fixed switch for a 35 mm back box. The highlight line that says plug-in conflicts with that. Treat it as wired.
What times can it run?
Buttons for 1, 5, 10, 15, 20, and 30 minutes, plus a long-press hold-on. It is not a 24-hour programmer.
The SURAIELEC two-pack, model TM06-UK, is £16.99 for a digital plug-in that states 18 on/off programmes, a weekly pattern, a random offset of 2–32 minutes, a manual on/off, and a rechargeable Ni-Mh battery, at 240 V AC, 13 A and 3120 W claimed. The star line is 4.5 from only nine reviews, so it is a higher star than NOVKIT and a much smaller sample. The saved texts are detailed and positive: lamps and small appliances through the week, a backlight readable in a dim room, and a random offset so lights are not on the same minute every night. One review saw the LCD lit from the internal battery before mains was connected. None of those nine describe a failed unit, which is not a durability record, and one review still calls them smart plugs, which this listing is not. The bullets do not say whether random mode applies in every programme. Indoor use is stated, and at 3.2 × 5.7 × 11.9 cm and 122 g it is the smaller digital body in the set.
Pros
Cons
Best for: You want 18 weekly programmes and a stated 2–32 minute random offset on a smaller digital body, and you can accept nine reviews.
Less suitable: You need a review sample in the thousands, or a mechanical dial with no menu.
Specifications
Common questions
How many programmes, and is there a random mode?
The bullets say 18 on/off programmes and a random mode that varies times by 2–32 minutes. They do not say whether random applies in every mode.
Will an aquarium pump run on it?
A customer question asks. The bullets name aquarium equipment and state 240 V AC, 13 A, 3120 W, indoor. They do not name a specific pump.
What keeps the clock in a power cut?
A rechargeable Ni-Mh battery, stated in the bullets and the battery-type field. One review saw the LCD lit before mains was connected.
The Defender Plugtimer1 at £7.95 is a mechanical 24-hour plug-in with 15-minute segments and a claimed load up to 3200 W, and it carries 4.4 from 14,239 amazon.co.uk reviews. Reviewers use it for lamps, an aquarium light, and holiday lights left on a schedule for months, and several say the dial needs no button sequence and no app. Some call the case silent next to an older ticking timer, while at least one unit has a continuous tick, so quiet is not a promise on every socket. One review describes the case running very warm on standby with nothing plugged in, which is a reason to feel the body after the first evening. Setting the segments is called slightly tricky at first, and the listing does not state a manual override or an outdoor rating. There is no battery claim, so after a power cut you turn the dial back to the time now. It is the top pick in this set because of that review sample, not because a lab scored it.
Pros
Cons
Best for: You want one 15-minute mechanical plug-in for a daily lamp or tank light, and you want the largest review sample in this set.
Less suitable: You need a weekly programme, a stated random offset, an outdoor rating, or a wired immersion.
Specifications
Common questions
Can this Defender timer be used outdoors?
The saved listing does not state an IP rating or outdoor use. The bullets describe indoor appliances, lamps, and holiday lights. Treat it as an indoor plug-in.
What on-time step does the listing state?
Each segment is 15 minutes, on a 24-hour dial, for a load the bullets put at up to 3200 W.
Does the listing state a manual override?
A customer question asks. The bullets do not say. Manual override is not stated.
This HBN two-pack, model BND-50/E12N, is £13.99 and keeps the 15-minute step, with a claimed load up to 3120 W and a star line of 4.4 from 1,667 reviews. Short reviews say it holds the times once the dial can be read, and they use the pair on indoor lamps, with one note of quiet running and another of an audible tick. The printed time marks are called small and faint, and one box arrived without instructions. The stated size is 3.3 × 7.7 × 7.7 cm, and one UK review says the body is too wide, centre to centre, to share a typical double socket with another plug. One early unit did not run until it was switched off and on again. A switch knob, a load indicator, and a child shutter are claimed. There is still no battery, so you reset the dial after a cut, and outdoor use is not stated.
Pros
Cons
Best for: You want a 15-minute HBN pair for indoor lamps on separate sockets, and you can read a small dial.
Less suitable: You need both halves of a double socket free, or large time marks you can read at a glance.
Specifications
Common questions
Can two of these share a double socket?
One UK review says the body is too wide, centre to centre, for adjacent plugs on most gangs. The stated size is 3.3 x 7.7 x 7.7 cm.
Is it indoor only?
The title says indoor. A customer question asks about outdoor lights. No IP rating is stated.
What protection does the listing claim?
A children protector, a grounded pin, a load indicator, and a switch knob, with a 15-minute minimum and a load up to 3120 W.
The MDCMLKS two-pack, model T-001, is £12.99 for two 15-minute mechanical plug-ins that state 13 A, 230 V, 50 Hz and 3120 W, with pins down for on and pins up for off. The listing line is 4.4 from 96 reviews, but only five UK texts are saved, and they are short and positive: easy, reliable, used in an unoccupied house, and the buyers would get the pair again. None of those five mention noise, heat, or a dead unit, which is not the same as a clean record across 96 people. The bodies are listed at 11.8 × 6 × 11.6 cm and 330 g in ABS, so they are not the slim Status shape. A customer question asks about outdoor lights and a manual override, and the bullets confirm neither. A fireproof-material line and a CE claim are seller text, not a report in this file. You are buying a stated 13 A dial with a thin written sample.
Pros
Cons
Best for: You want two stated 13 A, 15-minute dials, and you accept that only five written UK reviews are saved.
Less suitable: You need thousands of reviews, an outdoor rating, or a stated manual override.
Specifications
Common questions
Is the MDCMLKS timer for outdoor lights?
A customer question asks. The title says indoor. No IP rating is stated.
How is the dial set?
Pins down are on and pins up are off. Each pin is 15 minutes. The bullets claim up to 96 on/off steps in 24 hours at 13 A, 230 V, 3120 W.
How many reviews are saved?
The listing line is 4.4 from 96. The saved listing contains five review texts, all short and positive.
This HBN two-pack, model BND-50/E39, is £12.99 for a pair of 15-minute mechanical plug-ins that claim up to 3120 W, with a highlight that also says 13 A. Across 6,604 amazon.co.uk reviews the line is 4.3, and the sampled notes call the dial simple next to a digital menu, useful as a replacement for an older timer that had started to tick, and fine once the sheet is read. The pack fields disagree: included components say two timers, while Number of Items says 1, so check the box count on the page you open. One pair sat unused in storage and failed at the first try, and another review says a unit worked for about a week and then stopped, with the build called cheap. A switch knob and a child-shutter claim are on the bullets. No battery is stated, so a power cut still leaves the dial on the wrong time. Indoor use is what the highlight describes.
Pros
Cons
Best for: You want two 15-minute indoor dials for lamps in different rooms, and you will check that two timers are in the box.
Less suitable: You need a unit that must survive months in a drawer before first use, or a different programme each weekday.
Specifications
Common questions
How many timers are in this listing?
The highlight and included components say 2 timers. The Number of Items field says 1. The captured price is £12.99 for the listing as sold.
What is the shortest on period?
The bullets say a minimum setting of 15 minutes and a maximum of 24 hours, with a load up to 3120 W.
Does it claim a child shutter?
Yes. The bullets say a children protector and a grounded pin. That is a socket-shutter claim, not a digital child lock.
The HBN three-pack at £14.99 is the coarser mechanical plug-in in this set: the shortest on block is 30 minutes, and the highlight says 13 A / 2900 W while a bullet says up to 3120 W. The star line is 4.3 from 4,315 reviews. Reviewers say it does the timed job once the pins are understood, including a fan run through hot weather, and they accept thin plastic at this price because three sockets cover several rooms. The bullets say pins down are on and pins up are off, and new pins arrive pressed down, so a lamp can stay on all night if you plug in before you lift the pins you do not want. One reviewer spent about an hour on the instructions, and the pin sense felt reversed compared with other timers they already owned. The included-components line that says sound generators is a catalogue string, not a feature the bullets describe. You still need a trial run in the room, because there is no battery claim if the power drops.
Pros
Cons
Best for: You want three mechanical plug-ins for rooms that can live with a 30-minute step, and you will lift the pins that arrive down.
Less suitable: You need 15-minute blocks, or you will plug the timer in before you have set the pins.
Specifications
Common questions
Are the pins on or off when down?
The bullets say pins up means off and pins down means on, and that new pins arrive pressed down.
Why do two wattage figures appear?
The highlight says 13 A / 2900 W and the bullet says up to 3120 W. Both figures are on the listing. Use the figure printed on the unit you receive.
What is the shortest interval?
30 minutes, which is coarser than the 15-minute HBN plug-ins in this set.
The NOVKIT two-pack at £18.74 is a digital plug-in that states 10 on/off programmes, a weekly pattern, a random mode, and a built-in battery, at 230 V, 13 A and 2900 W claimed. It sits at 4.3 from 3,114 amazon.co.uk reviews, which is the large digital sample in this set. Reviewers use the week programme for fish-tank and reptile lights, and they use random mode while they are away, though one review says the offset did not feel truly random. The display is called easier to read than smaller digital timers, and several people moved to it because a mechanical dial ticked. Programming is described as difficult until the instructions are followed. The bodies are called quite big, at 6 × 13.5 × 4.8 cm and 420 g for the listing, and one unit in a pair arrived not working, with the seller sending a replacement. The title says home and indoor. No measured backup time is printed, only the battery claim, and a minimum on-step is not stated.
Pros
Cons
Best for: You want a weekly digital pair with a large review count, for tank lights or a random offset while you are away.
Less suitable: You want a dial you can set without a button sequence, or a slim body on a crowded socket.
Specifications
Common questions
Is this NOVKIT pack for outdoor sockets?
The title says home and indoor. No IP rating is stated. Do not treat it as an outdoor timer.
How many programmes does the listing state?
Up to 10 on/off programmes, each described as 24-hour and weekly programmable, plus a random mode.
Will the settings survive a power cut?
The bullets say a built-in battery memorises programmes during power outages. That is a listing claim, not a measured backup time.
The HBN immersion timer at £15.99 is a wired 16 A segment clock, 8.5 × 8.5 × 4.8 cm, with 15-minute steps and a claimed 48 on/off events on a 24-hour dial, rated 4.2 from 988 reviews. It is not a plug you put an immersion lead into. Reviewers who had it fitted for off-peak water say it is straightforward once it is on the wall, and the cover that customer questions ask about is in the listing. One review reports losing about an hour a day after a couple of weeks, the clock stops when the supply fails, and resetting it is called awkward. Segments are described as needing very small fingers, the plastic is called flimsy, and one reviewer found no earth terminal on the clock, so the earth was joined in a separate terminal. The listing claims a waterproof cover and a 15 mm minimum depth. That cover is not an outdoor or bathroom-zone rating, and the bullets do not describe the terminals.
Pros
Cons
Best for: You already have a wired immersion circuit and a competent person to fit a 16 A segment timer.
Less suitable: You hoped to plug a 13 A timer into the cylinder, or you cannot isolate the circuit and prove it dead.
Specifications
Common questions
Is this a plug-in timer?
No. The title is a wired 16 A immersion segment timer. The bullets say wire connection.
Does it keep time through a power cut?
The listing does not claim a battery. Reviews say the clock stops if the power is cut.
Does the listing show an earth terminal?
It does not describe the terminals. One UK review says there is no earth connection on the clock and the earth was joined in a separate terminal.
The Status mini, model ION24HMINIT10, is £4.25 for a 15-minute mechanical plug-in at 4.2 from 117 reviews, and the saved bullets do not state amps or watts. One UK review gives the method the sheet does not: set the centre dial to the time now and press the pegs down for the times you want the appliance on. Reviewers say it works once that dial is understood, and the body is a compact UK plug-in listed at 5 × 10 × 10 cm and 120 g. The plastic is called thin, the segments and any instructions are called small, fiddly, or missing, and one buyer replaced the unit because they did not trust it to keep going. If you read down as off, the lamp stays on. Rank 1 in Timers on the capture is a sales rank, not a load test. There is no battery claim, and heaters are named in a bullet with no figure to check.
Pros
Cons
Best for: You want the lowest captured price for a 15-minute dial, and you will set the pegs yourself because the sheet may be missing.
Less suitable: You need a printed amp rating before you connect a heater, or a large instruction sheet.
Specifications
Common questions
Which way do the pegs go?
One UK review says press the pegs down for the times you want the appliance on, then set the centre dial to the time now. The bullets do not repeat that sentence.
Is a wattage stated?
No. Heaters are named in a bullet with no amp or watt figure.
Is this the same listing as the other Status timer?
No. This ASIN is B0DPG6X41Z, model ION24HMINIT10, £4.25, 4.2 from 117 reviews. The other is B0DPG6XCXX, ION24HT10, £4.95.
Eleven amazon.co.uk timer-switch listings were read for load, programme, power-cut behaviour, the UK plug and the review sample. The score on each row is the saved star rating mapped to 100. It is not a laboratory test. The weights below are the order of those buying checks, and they sum to 100. They are not a second formula behind the star map. The top pick is the mechanical plug-in with 14,239 reviews. The best value is the daily dial at about £4.95.
Load and connection
30%A portable appliance needs a plug-in whose stated maximum covers that appliance, one plug only. A wired immersion needs a timer in the 16 A class. A light that should go off after a few minutes needs a countdown switch.
Programme shape
25%The same times every day suit a mechanical segment dial. Different weekdays, or a random offset while you are away, need a digital plug-in that states those features. One three-pack in this set steps in 30 minutes.
Power-cut behaviour and noise
20%Mechanical dials have to be turned back to the time now after a power cut. A stated battery is a listing claim, not a measured backup time. A tick is a common reason to move a mechanical timer, and silence is not guaranteed on every unit.
UK plug, marks and instructions
15%Regulation 35 of the Electrical Equipment (Safety) Regulations 2016 requires compatibility with BS 1363 sockets. A CE or UKCA mark on a listing is a claim. Several cheap listings are reviewed as having no useful instructions.
Review evidence
10%Stars in this set sit between 4.2 and 4.5. Review count separates a known listing from a new one. A 4.5 from nine reviews is not stronger evidence than 4.4 from 14,239.
Start with the connection and the load, then the programme, then what a power cut does. Price comes after those three. The notes below follow that order for these 11 amazon.co.uk listings. None of the scores is a laboratory test.
A timer switch turns a load on and off to a programme. On amazon.co.uk the usual domestic buy is a plug-in for a BS 1363 socket, for a lamp, a fan, holiday lights or an aquarium. A wired immersion is a different job. It needs a segment timer in the 16 A class, with a wire connection, rather than a 13 A plug you push a cylinder lead into. A light that should go off after a few minutes needs a countdown switch with fixed minute buttons, rather than a 24-hour dial.
A cylinder timer in this set is a wired 16 A segment clock. A 13 A socket timer is the wrong object for that circuit. Have a competent person fit the wired unit and isolate the supply first.
On several mechanical listings, pins down mean on, and new pins arrive pressed down. The lamp can stay on all night if you plug in before you lift the pins you do not want. Set the time of day as well as the segments.
Random mode in this set is a stated feature on the digital plug-ins. A mechanical title that says security still repeats the same minutes every day. It also loses the time in a power cut, because no battery is claimed.
Decide the connection before the price. A portable lamp, fan or tank light needs a plug-in, and the stated maximum has to cover that one appliance. Defender states up to 3200 W. Several HBN plug-ins state up to 3120 W, and one highlight also says 13 A or 2900 W. MDCMLKS states 13 A, 230 V and 3120 W. NOVKIT states 230 V, 13 A and 2900 W. SURAIELEC states 240 V AC, 13 A and 3120 W. Treat 3120 W as a listing claim, not a tested continuous heater rating.
The same times every day suit a mechanical 15-minute dial. The HBN three-pack is the 30-minute step in this set. Different weekdays, or a random offset while you are away, need a digital plug-in that states those features. NOVKIT states 10 programmes and random mode. SURAIELEC states 18 programmes and a random offset of 2 to 32 minutes. Random mode is that stated digital feature. A security word on a mechanical title is not the same thing.
Three typical situations, each with a recommendation from this comparison.
You want one mechanical plug-in for a lamp, a fan or an aquarium light, with the same times every day. The Defender segment timer is about £7.95, with 4.4 from 14,239 reviews and 15-minute steps. Reset the dial after a power cut. Quiet running is not consistent on every unit.
You want a weekly pattern or a random offset, and you will follow a button sequence. The NOVKIT two-pack is about £18.74, with 4.3 from 3,114 reviews, 10 programmes and a battery claim. One review says the offset did not feel truly random. The title is for indoor use.
You already have a wired immersion circuit and a competent person to fit a 16 A segment timer. The HBN immersion timer is about £15.99, with 4.2 from 988 reviews and 15-minute steps. It is a wired clock, not a 13 A plug-in. The clock stops in a power cut.
In this set of 11 amazon.co.uk listings, the top pick is the Defender 24-hour segment timer at about £7.95, with 4.4 from 14,239 reviews. It is a 15-minute mechanical plug-in with a claimed load up to 3200 W, and the score of 88 maps that star line. The best value is the Status IONOS plug-in at about £4.95, with 4.5 from 87 reviews, because it is the low spend for a daily mechanical dial. Neither figure is a laboratory test. A 13 A plug-in does not replace a wired 16 A immersion timer.
Status IONOS 24 Hour Plug-in Timer Switch
About £4.95 for a 15-minute mechanical dial, 4.5 from 87 reviews. Score 90, mapped from the star line. No amp or watt rating is stated, and at least two reviews say the timer did not work.
