An English hallway you will maintain
You want several screw-in alarms and you will change a 9 V cell when it chirps. The ELRO FS1801 four-pack is about £31.15, with 4.5 from 7,232 UK reviews. The 10-year wording on that listing is not a sealed cell.
Elro smoke alarm comparison 2026
The best Elro smoke alarms, compared.
Top pick: ELRO FS1805 10-pack Best value: ELRO FS1805 2-pack – Highest value block that is not the top pick: about £16.99 for two magnetic alarms at 4.4 from 1,134 reviews. Updated October 2026.
You want a hallway warning you can fit yourself, and these Elro smoke alarm listings do not all mean the same battery. The six amazon.co.uk units here are battery-powered optical alarms in white plastic, for halls and landings in an existing home. They are not a mains system for a new dwelling, and none is interlinked. Tell them apart by the cell and the fixing. The packs include a replaceable 1-year battery and screws. A 10-year protection bullet sits next to that 1-year cell, so it is not a sealed battery. The packs state a 5-year cell and magnetic pads. The ELRO FS4610 is one slim alarm with a built-in 10-year battery. Every listing claims EN 14604 and a photoelectric sensor. A heat alarm belongs in the kitchen, not these units. The [Elro smoke alarm buying guide](/hub/fire-protection/elro-smoke-alarm/sub/elro-smoke-alarm-buying-guide) sets out battery, mount and pack size. None of the six is described as interlinked, smart, or a carbon monoxide alarm.

The best Elro smoke alarms in detail
Our view
The ELRO FS1805 ten-pack, listed at about £64.99, claims ten magnetic photoelectric alarms with batteries stated as a 5-year lifespan, and amazon.co.uk shows 4.6 from 14 reviews. The four written reviews are from Belgium and Germany, not the United Kingdom, so that star line is not British opinion and it does not outrank the four-pack’s 7,232 reviews. Those texts mention batteries, magnets and screws in the box, and also outer packs that looked already opened with some cells already inserted. The bullets say a 5-year warranty and the specification line says 2 years. Compatible devices lists a smartphone, and no bullet explains an app, so this is not treated as a smart alarm. At about £6.50 an alarm it is not the cheap way into the FS1805 line once the thin review record is in the score.
Pros
- Ten FS1805M alarms with magnetic sets at about £64.99
- Batteries stated as 5 years and described as replaceable
- Test button and low-battery warning on the listing
- A Belgian review also mentions screws in the box
Cons
- 4.6 from 14 reviews, and the written texts are not from the United Kingdom
- Warranty conflict: 5 years in the bullets, 2 years in the specification
- Reports of packs that looked opened, with cells already fitted
- Smartphone in the spec table is not an explained app
Best for: You already know the FS1805 from the two-pack or six-pack and you specifically need ten magnetic units.
Less suitable: You are using 4.6 from 14 as a reason to prefer this pack over the four-pack or the pair at about £16.99.

Common questions
Which warranty applies to the 10-pack?
The bullets say a 5-year warranty. The specification line says 2 years. Both are on the listing.
Are the written reviews from the United Kingdom?
The listing shows 4.6 from 14 reviews. The four written reviews are from Belgium and Germany, not the United Kingdom.
Is this a smart alarm because smartphones are listed?
The specification says compatible devices include a smartphone. No bullet explains an app, so this comparison does not treat it as a smart alarm.
Our view
The ELRO FS1801 four-pack, listed at about £31.15 on 19 October 2026, is four photoelectric alarms about 9 cm across, with screws and a replaceable battery the listing describes as a 1-year lifespan. On amazon.co.uk it is 4.5 from 7,232 reviews, and the review texts are from the United Kingdom, which is why it is the top pick in this set. Reviewers fit them with screws and a twist-on base, and several call the test tone loud for the size. The same bullets that say 10-year protection also say the battery lasts one year, so that phrase is not a sealed cell. The base is fiddly once the 9 V cell is clipped in, a small red flash bothers some light sleepers, and one buyer reported three of four units false-alarming after about a year even after a battery change. Another reported one unit dead out of the box. You still press the test button yourself, and this score is not a fire test.
Pros
- 4.5 from 7,232 amazon.co.uk reviews, with UK review text
- Screw mounting and a twist-on base described in reviews
- Replaceable 9 V cell, supplied wrapped, with a low-battery warning on the listing
- Four alarms at about £31.15 on 19 October 2026
- Photoelectric sensor and an EN 14604 claim
Cons
- The 10-year protection bullet sits next to a 1-year battery
- Twist-on base is fiddly after the cell is fitted
- False alarms after about a year in one multipack report
- A unit in the pack can be dead on arrival
Best for: Several screw-in hallway alarms, a 9 V cell you will change when it chirps, and the largest UK review sample in this set.
Less suitable: You clicked because of the 10-year wording, or you need a sealed cell and a linked system.

Common questions
Does the FS1801 4-pack have a sealed 10-year battery?
No. The listing includes batteries with a 1-year lifespan and says the battery is replaceable. A bullet also uses the words 10-year protection.
How do you fit this 4-pack?
The box includes mounting materials. Reviews describe screws and a twist-on base. A magnetic kit is not listed.
What kind of sensor is it?
Photoelectric. The listing claims EN 14604. It does not state a decibel figure.
Our view
The ELRO FS1801 ten-pack, listed at about £53.88, is the same screw-mounted photoelectric alarm with batteries the listing still describes as a 1-year lifespan. amazon.co.uk shows 4.5 from 7,228 reviews, but the written reviews match the four-pack, including comments about a pack of four, so that count is a shared pool. Buyers who write about the family praise a loud test tone and a cell you can change when it chirps. The title says 10-year sensor while a bullet says the battery lasts one year. False alarms after about a year, and a unit dead on arrival, appear in that shared sample. At about £5.40 an alarm it covers more rooms only if you will keep 9 V cells in a drawer. The listing prints an item weight of 90 g.
Pros
- Ten screw-in FS1801 alarms at about £53.88
- Replaceable 1-year batteries and mounting materials included
- Same photoelectric sensor and EN 14604 claim as the four-pack
- Low-battery warning and a test button on the listing
Cons
- Review texts match the four-pack, so 7,228 is not a separate sample
- Title says 10-year sensor beside a 1-year cell
- Shared reports of a fiddly base and false alarms
- Printed weight of 90 g does not read like a ten-alarm mass
Best for: A lot of rooms with the same screw-in alarm, and a 9 V cell you will change in every unit.
Less suitable: You are treating the review count as proof of this ten-pack alone, or you want a sealed battery.

Common questions
Is the battery in the 10-pack sealed for 10 years?
No. Included batteries are described as a 1-year lifespan and the battery is replaceable. The title says 10-year sensor and a bullet says 10-year protection.
Are the reviews only about this 10-pack?
The written reviews match the FS1801 4-pack, including comments about a pack of four. Treat the 7,228 reviews as a shared pool.
Does it mount without tools?
No. The listing includes mounting materials, and the shared reviews describe screws rather than magnets.
Our view
The ELRO FS1805 two-pack, listed at about £16.99, is two photoelectric alarms with magnetic pads and batteries the listing states as a 5-year lifespan. It is 4.4 from 1,134 amazon.co.uk reviews, mostly from the United Kingdom, and rank 13 in Smoke Alarms, which is why it carries the best-value mark in this set. Reviewers like the tool-free pads and a compact unit that sounds loud on test. The 5-year claim is not settled: the ELRO FS1805M page also says at least 3 years, and reviews include a cell dead after about four months and another after about a year. One buyer could not stick the pads to a rough popcorn ceiling, and another pack arrived without the magnetic discs. The listing does not answer a shopper question about a hush button. It is the low shelf price for a small home, and the wrong mount if the ceiling will not hold adhesive.
Pros
- Two alarms at about £16.99, rank 13 in Smoke Alarms
- 4.4 from 1,134 reviews, mostly United Kingdom
- Magnetic pads that many buyers fit without a drill
- Replaceable battery stated as 5 years, with a 5-year warranty line
Cons
- Reviews include cells dead after about four months and about a year
- Pads fail on a rough popcorn ceiling
- A pack can arrive without the magnetic discs
- Hush button is not confirmed on the listing
Best for: Two hallway alarms on a smooth ceiling, a cell you can change by pulling the unit down, and a budget of about £16.99.
Less suitable: The ceiling is rough, you need a cell that is guaranteed for five years, or the law where you live demands a linked system.

Common questions

Yes. The listing includes two magnetic mounting sets. One review could not stick the pads to a rough popcorn ceiling.
How long does the battery last?
The listing says 5 years and the batteries are replaceable. Reviews include a cell dead after about four months and another after about a year.
Does the listing confirm a hush button?
No. A shopper question asks about a hush button, and the bullets do not answer it.
Our view
The ELRO FS1805M six-pack, listed at about £37.60, is six magnetic photoelectric alarms at about £6.27 each, with 4.3 from 3,052 amazon.co.uk reviews. UK reviews praise stick-on fitting, a loud test, and taking a unit down to change the cell. Random alarms, including a short note of a constant false alarm, are the complaint that repeats. The listing prints an item weight of 58 g for a six-count product, which is not a figure to plan a fitting around. The batteries are replaceable and stated as 5 years, with the same manufacturer wording conflict as the two-pack. Real-fire performance is not shown in the reviews. A rough ceiling may still need a screw fixing this box does not lead with.
Pros
- Six magnetic alarms at about £37.60
- 4.3 from 3,052 amazon.co.uk reviews
- Tool-free pads, and reviewers take them down to change the cell
- Test button and low-battery warning stated on the listing
Cons
- Random and constant false alarms appear in UK reviews
- The 5-year cell is a claim, not a measured life
- Printed weight of 58 g for a six-count item
- Adhesive pads are the mount London Fire Brigade ranks below screws
Best for: Several smooth ceilings, and the magnetic FS1805 in one box.
Less suitable: You need screws as the main fixing, or you are choosing from a star line of 14 reviews on the ten-pack instead.

Common questions
Is the 6-pack tool-free to fit?
The listing says the magnetic kit is tool-free and includes six magnetic mounting sets. Reviews describe stick-on fitting and taking a unit down to change the battery.
What do reviewers complain about?
UK reviews include random alarms and a short note of a constant false alarm. Others call the pack compact, loud and good value.
What is the listed weight?
The listing says 58 g for the 6-count item. That figure is what the page prints, and it is not a weight to plan a fitting around.
Our view
The ELRO FS4610, listed at about £21.99, is one photoelectric alarm measuring 11.5 × 11.5 × 2.3 cm, with a built-in battery the listing says you do not replace for 10 years. It is 4.2 from 987 amazon.co.uk reviews, and many of the first 50 texts are not in English. The English ones call it flat, loud enough on test to wake someone, and straightforward to screw up, with a discreet LED. A UK review says it is not wireless and cannot be interconnected, and another expected magnets that are not in the included list. The manufacturer page says not to use a magnet kit and that the alarm is not connectable. The title’s STIWA and Q wording is not a UK laboratory result. You replace the whole alarm when the sealed cell is finished. About £21.99 buys one unit rather than a hallway pair.
Pros
- Built-in 10-year battery, not a user-replaceable cell
- 2.3 cm thick, with screw mounting in the reviews
- 4.2 from 987 amazon.co.uk reviews
- Low-battery warning and a test button on the listing
- 10-year warranty line on the listing
Cons
- One alarm at about £21.99, dearer per unit than the multipacks
- Not wireless, so it will not interconnect
- No magnetic kit, despite some buyers expecting one
- STIWA and Q wording on the title is not a UK lab result
Best for: One slim sealed alarm on a ceiling you can screw into, and a test button you will press rather than a case you will open.
Less suitable: You need radio interlink, a magnetic fit, or several alarms for the price of this one.

Common questions
Can you change the battery in the FS4610?
No. The listing includes a built-in battery with a 10-year lifespan and says you are protected without replacing the battery.
Does this listing include magnetic mounts?
No. Included items are the alarm, the built-in battery, mounting material and a manual. One UK review says magnets were expected and were not in the box.
Will it link to other alarms?
A UK review says it is not wireless and cannot be interconnected. The listing bullets do not describe a radio link.
How we compared
Six amazon.co.uk listings were scored on 19 October 2026 from the review notes and the manufacturer and UK public pages already used for this comparison. Prices, star lines and review themes come from those listings. A score is not a smoke-sensitivity test, and it is not a claim that one alarm is the safest in the UK. The three weights below sum to 100.
1
Amazon evidence
40%Star rating scaled by review count, maximum 40. UK review text scores higher than a sample whose written reviews are from other countries. A shared pool that repeats another listing’s texts is not a second independent sample. Repeated false alarms, early cell failure and dead-on-arrival units come off this block.
2
Published limits
35%Maximum 35. A battery story that matches the included parts, a mount you can use, a photoelectric sensor with an EN 14604 claim, and a test button plus a low-battery warning the listing states. A 10-year bullet next to a 1-year cell, a 5-year claim the manufacturer page also undercuts, or a warranty line that disagrees with itself costs points.

Value
25%Maximum 25. Shelf price in GBP against pack size and a real review line. The lowest price per alarm does not win when the review texts belong to another pack, or when the cell claim is the thing you would be buying.

Elro smoke alarm buying guide
An Elro smoke alarm in this set is a battery optical alarm, not a linked mains system. Match the cell you will actually change, the mount the ceiling will hold, and the rule where the home is, before you compare the shelf price. The six prices below are the amazon.co.uk lines on 19 October 2026, from about £16.99 to about £64.99. A score here is not a smoke-sensitivity test.
What is an Elro smoke alarm?
An Elro smoke alarm, in the six amazon.co.uk listings kept here, is a battery-powered optical alarm in white plastic, sold as a single unit or a multipack. UK buyers use them as extra warning on halls and landings in existing homes, not as a mains fire-alarm system for a new dwelling. None of the six is described as interlinked, smart, or a carbon monoxide alarm. Every kept listing claims EN 14604 and a photoelectric sensor.
Best for
- Owner-occupiers in England who want a simple hallway alarm and will test it
- A smooth ceiling where magnetic pads can hold, at the two-pack price
- One slim sealed alarm when you will buy a heat alarm separately
Not ideal for
- A new dwelling that needs a Grade D2 mains system
- Scotland, Welsh rented homes, or a Northern Ireland private tenancy treated as covered by these units alone
- A kitchen or a bathroom, or a rough ceiling with glue pads
Mistakes to avoid
- 1
Reading the FS1801 as a sealed 10-year alarm
The four-pack and the ten-pack include a replaceable battery the listing describes as a 1-year lifespan. A bullet that says 10-year protection, and a ten-pack title that says 10-year sensor, sit next to that 1-year cell. The sealed 10-year battery in this set is the FS4610.
- 2
One alarm for a whole house, or pads on a poor ceiling
These units are extra warning on the escape route, not a whole-house system. Magnetic pads on the FS1805 fail on a rough popcorn ceiling, and a pack can arrive without the discs. London Fire Brigade prefers screws to glue. The FS4610 manufacturer page says not to use a magnet kit.
- 3
Using a title badge as a UK test
STIWA and Q wording on the FS4610 title is not a UK laboratory result. Covering the case with paint is a separate fitting mistake. These alarms are not carbon monoxide alarms, and they are not interlinked. Check the nation before you treat a 9 V pack as the legal fit.
What to weigh up
Battery you will maintain
HighThe battery you will actually maintain is the main split. FS1801 listings include a 1-year replaceable battery, and reviews describe a 9 V cell you change when it chirps. The four-pack and the ten-pack both carry a 10-year protection line beside that 1-year cell. Read the included-parts line, not the longer phrase. The ten-pack title says 10-year sensor while a bullet still says the battery lasts one year. FS1805 listings say 5 years and describe the batteries as replaceable.
Duty, mount and place
HighDuty depends on where the home is. England’s private-rented rules require at least one smoke alarm on each living storey and do not fix mains versus battery. The GOV.UK landlord booklet prefers sealed batteries. New English dwellings under Approved Document B are guided to Grade D2 Category LD3 mains alarms to BS 5839-6 and BS EN 14604. Scotland requires interlinked ceiling smoke alarms plus a kitchen heat alarm, and rejects user-replaceable batteries for that system.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
Two alarms on a smooth ceiling
You want a low shelf price and you can pull the units down to change a cell. The ELRO FS1805 two-pack is about £16.99, with magnetic pads and a battery stated as 5 years. Pads fail on a rough ceiling.
One slim sealed alarm
You want a built-in 10-year cell and a ceiling you can screw into. The ELRO FS4610 is about £21.99 and is not wireless. Buy a separate heat alarm, and a linked system where the law where you live requires one.
Common questions about Elro smoke alarms
Which Elro smoke alarm is the top pick?
The top pick is the ELRO FS1801 four-pack at about £31.15, score 79. On amazon.co.uk it is 4.5 from 7,232 reviews, and the review texts are from the United Kingdom. It is four photoelectric alarms with screws and a replaceable battery the listing describes as a 1-year lifespan. A 10-year protection bullet sits on the same page and does not mean a sealed cell. This score is not a fire test.
Which listing is the best value?
The best value is the ELRO FS1805 two-pack at about £16.99, score 71. It is two photoelectric alarms with magnetic pads and a battery stated as a 5-year lifespan, at 4.4 from 1,134 amazon.co.uk reviews. That value block is the highest that is not the top pick. Reviews include cells that failed early, and pads that would not hold on a rough ceiling. The listing does not confirm a hush button.
How much does an Elro smoke alarm cost?
On 19 October 2026 these six shelves run from about £16.99 to about £64.99. The FS1801 four-pack is about £31.15 and the ten-pack about £53.88, about £5 to £8 an alarm, with a cell you change. The FS1805 two-pack is about £16.99, the six-pack about £37.60 and the ten-pack about £64.99, about £6 to £9 an alarm. One FS4610 is about £21.99. Per-alarm figures divide the shelf price by the pack count. Prices move.
Does the FS1801 have a sealed 10-year battery?
No. The FS1801 four-pack and ten-pack include batteries the listings describe as a 1-year lifespan, and the battery is replaceable. Reviews describe a 9 V cell. A bullet also uses the words 10-year protection, and the ten-pack title says 10-year sensor. That wording is not a sealed cell. The sealed 10-year battery in this set is the FS4610, one alarm at about £21.99.
Do these alarms meet the rules in every UK nation?
Not as a standalone set. England’s private-rented rules require at least one smoke alarm on each living storey and do not fix mains versus battery. Scotland, Welsh rented homes and Northern Ireland private tenancies expect interlinked alarms these listings do not provide. An EN 14604 claim does not by itself meet those rules. The Elro smoke alarm UK rules page sets out each nation.
Where should I fit one?
Fit these optical alarms on the ceiling of the escape route, about 30 cm from walls and lights. Do not fit them in kitchens or bathrooms. A heat alarm belongs in the kitchen. Press the test button weekly, including with bedroom doors shut. If the alarm sounds and you cannot account for it, get out, stay out and call 999. For alarms outside this Elro slice, see the smoke alarm comparison.
When should I call a professional?
Call a professional for a Part B mains system, and for mains interlink where the nation requires an electrician. Also call when someone would be slow to escape, and when an alarm keeps false-alarming after cleaning, a new replaceable cell, and a move away from steam. Do not treat a 9 V pack as the legal fit until you have checked the nation. These units are not carbon monoxide alarms.
Our verdict
The top pick is the ELRO FS1801 four-pack, score 79, at about £31.15. It leads because that price comes with 4.5 from 7,232 reviews, UK review text, screws, and a battery the included-parts line calls a 1-year cell. The 10-year bullet still sits on that same listing. The best value is the ELRO FS1805 two-pack, score 71, at about £16.99, two magnetic alarms with a stated 5-year cell at 4.4 from 1,134 reviews. Early cell failures and pads that fail on a rough ceiling stay in that score. The FS1805 ten-pack’s 4.6 from 14 reviews does not outrank either of them. Neither mark is a lab result.
