The best Burg-Wächter safes, compared.
Top pick: Burg-Wächter FP 22 K – Largest independent review file, a stated fire time, a two-year warranty, and a lock line that matches the title, at £42.00. Best value: Burg-Wächter Favor S3 E – £57.99 for a PIN, an emergency key, and 832 reviews on this ASIN. The cheaper S3 K title and lock field disagree. Updated October 2026.
A Burg-Wächter safe in this UK set is either a light furniture safe or the FP 22 K fire-protection document box, for a cupboard, a desk, or a floor anchor, not a certified strongroom. A typical listing does not state EN 1143-1, EN 14450, or Sold Secure. There was no fire test and no attack test. Favor is the economy freestanding home safe: a single-walled body and, on the UK maker page, a double-walled door. Version K is a mechanical lock with two keys. S3 K and S3 E are the small size. S5 K is the larger key safe, 18.6 litres on the listing and the UK table. How to choose is set out in the [Burg-Wächter safe buying guide](/hub/safes-and-secure-storage/burg-waechter-safe/sub/burg-waechter-safe-buying-guide).

Question 1 of 2
What are you putting in it?
The Burg-Wächter FP 22 K is a 5.6-litre key-lock document box at £42.00, listed at 9 kg, with a stated fire time of 30 minutes up to 1,093°C. Across 1,548 amazon.co.uk reviews it sits at 4.4, the largest file in this set, and the listing gives a two-year warranty. Reviewers treat it as a fire box for paper rather than a burglary safe, and the water-resistance field says Not Water Resistant. The bullets say it will take A4 documents, while reviews often say a flat sheet is tight or curls and that a folder or envelope does not fit. Floor mount is prepared for screws up to 6 mm, and the maker page says those screws are not in the box. The material line is Fireproof Polymer. Burg-Wächter ties the fire claim to UL 72 and an internal temperature under 90°C, though the amazon.co.uk listing does not print UL 72. It is the top pick in this set when you want that fire sentence and you can live with the chamber.
Pros
Cons
Best for: Wills and certificates when you want a stated fire time and can accept a tight A4 chamber.
Less suitable: Cash or jewellery in a steel cupboard box, or any policy that names EN 14450 or EN 1143-1.
Specifications
Common questions
Is the FP 22 K waterproof?
The listing sets Water Resistance Level to Not Water Resistant.
Will a flat A4 sheet fit?
The bullets say the box will fit up to A4 documents. Amazon reviews often say a flat sheet is tight or curls, and that a folder or envelope does not fit.
Can it be fixed to the floor?
Mounting Type is Floor Mount. The bullets say it is prepared for ground anchoring for screws up to 6 mm. The listing does not say those screws are in the box.
The Favor S5 K is the larger key safe at £80.50, with 18.6 litres and a single-walled metal body stated in the title and a bullet. Lock Type says key, with a dual locking system and two keys, while Control Type says Button control, which the listing does not explain. The star line is 4.4 from 654 reviews, and the review text matches the S3 K listing, so there is no size-specific sample for the extra litres. Title weight is 6 kg and item weight is 6.6 kg. Mounting is flush, with a rear-wall anchor. No fire time is stated, water resistance is Not Water Resistant, and the warranty field says no guarantee. The extra spend over the smaller key Favor buys capacity inside this set, not an EN 14450 grade.
Pros
Cons
Best for: A cupboard that can take about 250 × 350 × 250 mm when you want more than about 10 litres and you still accept a furniture safe.
Less suitable: A shopper who reads 4.4 from 654 as proof of this size, or who needs a fire sentence or a named insurer grade.
Specifications
Common questions
What lock does the Favor S5 K have?
Lock Type says Key. The bullets say a dual locking system and two keys. Control Type says Button control, which the listing does not explain.
Is the body single-walled?
The title and a bullet both say a solid single-walled body.
What is the listed capacity?
The attribute table says 18.6 litres. A bullet says the safe is for a passport, cash, or jewellery.
The Favor S3 K is listed at £52.34 with a title that says an electronic combination lock, while Lock Type and the bullets say a double-bit key and two keys. The attribute table gives 10.2 litres. The star line is 4.4 from 654 reviews, and that text matches the Favor S5 K file, so it is not a separate sample. Item weight is 4.39 kg and a bullet says 24.1 kg, which you cannot plan a shelf around. Mounting type is recessed, with a rear-wall anchor and mounting material in the bullets. The listing does not state a fire time, water resistance is Not Water Resistant, and the warranty field says no guarantee. Read the key line as the lock you are buying, and do not trust the title until it matches.
Pros
Cons
Best for: A small key cupboard box only after you have checked that the page you order still says a double-bit key.
Less suitable: Anyone who wants a PIN, a stated fire time, or a review file that belongs to this size alone.
Specifications
Common questions
Is the Favor S3 K electronic?
The title says an electronic combination lock with batteries. The bullets say a double-bit lock and two keys, and Lock Type says Key.
Is it fireproof?
The listing asks the question and does not state a fire time or a certificate. Water resistance is Not Water Resistant.
Can it be fixed in place?
Mounting Type is Recessed. The special-features line mentions an anchoring option in the rear wall, and the bullets include mounting material.
The Favor S3 E is the electronic model at £57.99, with a PIN, a mechanical emergency lock, and four AA batteries named in the bullets. It has 4.3 from 832 amazon.co.uk reviews, a file of its own rather than the shared 654 on the key listings. The bullets say 8.6 litres and a single-walled metal body, and they include mounting material. One UK review says the emergency key is too thin to open the flap, and another says the emergency keys arrived locked inside with no batteries fitted. Outside dimensions disagree between the title, the bullets, and the attribute table. The listing does not state a fire time, and the warranty field says no guarantee. It is the best value in this set when you want a code and you will keep a working emergency key outside the box.
Pros
Cons
Best for: A cupboard or desk where you want a code and you will store the emergency key somewhere else.
Less suitable: A buyer who will keep the only key inside the safe, or who needs a stated fire time for paper.
Specifications
Common questions
Does the Favor S3 E have a backup key?
The bullets say a mechanical emergency lock, and Lock Type says Electronic, Key. One UK review says the key is too thin to open the flap.
Are batteries included?
The bullets include four 1.5 V AA batteries. One review says the emergency keys were locked inside with no batteries fitted.
Is it fireproof?
The listing asks the question and does not state a fire rating. Water resistance is Not Water Resistant.
For this comparison we scored four amazon.co.uk Burg-Wächter listings on 16 October 2026. A shared review dump does not count twice. The score is an editorial figure from 0 to 100. It is not the star rating times 20, and it is not a fire test, an attack test, or a laboratory score.
Amazon stars
30%The amazon.co.uk star average is scaled to a 30-point cap, rounded half up. A 4.4 line is 26 points. That star line stays the listing score. It is not the editorial total.
Review volume
20%1,000 or more reviews on this ASIN alone take 20 points. 500 to 999 on this ASIN alone take 16. A star line shared with another ASIN in this set, with the same review text, takes 6 on the listing the text can attach to and 4 on the listing with no size-specific reviews.
Listing clarity
20%Lock fields that agree take 8 points, or 0 if the title and Lock Type fight. Sizes without a fight take 4, one fight takes 2, and two fights take 0. A fire or water line that is explicit takes 4. A warranty term that is printed takes 4, or 2 if the field says no guarantee.
Stated job
15%The listing’s role has to match a job you can name. A fire-and-paper box takes 13. A larger key cupboard box takes 12. An electronic cupboard box takes 12. A small key box whose title fights the lock takes 8.
Price in this set
15%£42 takes 15 of the 15 price points. About £52 takes 12. About £58 takes 10. £80.50 takes 6. Deductions then cover a tight A4 fit, floor screws missing from the box, a thin emergency key, keys locked inside, a title clash, shared review text, and an unexplained control line.
Shop the job before the badge on the door. A stated fire time for paper points to the FP 22 K. Cash or a watch in a cupboard points to a Favor. A named insurer grade is none of these four. Favor S3 and S5 are size steps, not EN 14450 levels S1 and S2. Prices in this extract run from £42.00 to £80.50 on amazon.co.uk. Count the shared 654-review line once.
A Burg-Wächter safe in this comparison is one of two families. Favor is the economy freestanding home safe: a single-walled body and, on the UK maker page, a double-walled door. Version K is a mechanical lock with two keys. Version E is an electronic combination, a mechanical emergency lock, and four AA batteries. S3 K and S3 E are the small size. S5 K is the larger key safe, 18.6 litres on the listing and the UK table. S3 and S5 are size steps. They are not EN 14450 levels S1 and S2.
S3 and S5 are size steps on the Favor range. They are not EN 14450 security levels S1 and S2. None of these four listings prints EN 14450, EN 1143-1, or Sold Secure.
The title says an electronic combination lock. Lock Type and the bullets say a double-bit key and two keys. The electronic model in this set is the Favor S3 E.
Favor S3 K and Favor S5 K share the star line and the same review text. Count 654 once. It is not a separate sample for the larger chamber.
Start with the job, then the litres. A stated fire time for paper points to the FP 22 K: 30 minutes up to 1,093°C, 5.6 litres, and a listing that says it is not water resistant. The bullets say the box will fit up to A4 documents. Reviews often say a flat sheet is tight or curls, and that a folder or envelope does not fit. Burg-Wächter ties the fire claim to UL 72. The amazon.co.uk page does not print UL 72, and UL 72 is not an EN 1047-1 paper class.
Read the lock field, not the title. Favor S3 K is titled as electronic. The bullets and Lock Type say a double-bit key and two keys. The electronic model is Favor S3 E: a PIN, a mechanical emergency lock, and four AA batteries in the bullets. One UK review says that emergency key is too thin to open the flap, and another says the emergency keys arrived locked inside with no batteries fitted. Keep a working emergency key outside the box. Favor S5 K is a key lock with two keys.
Three typical situations, each with a recommendation from this comparison.
You want a stated fire time for paper, and you can accept a tight A4 chamber. The FP 22 K is a 5.6-litre key-lock document box at £42.00, with 4.4 from 1,548 reviews and a two-year warranty. The listing says it is not water resistant, and floor screws are not in the box.
You want a PIN for a cupboard or a desk, and you will keep the emergency key somewhere else. The Favor S3 E is £57.99, with 4.3 from 832 reviews on this listing, four AA batteries, and mounting material in the bullets. No fire time is stated.
The cupboard can take about 250 × 350 × 250 mm and you still want keys, not a code. The Favor S5 K lists 18.6 litres and a single-walled body at £80.50. The 4.4 from 654 reviews matches the S3 K file, so it is not a separate test of this size, and it is not a printed EN grade.
The top pick in this set of four is the Burg-Wächter FP 22 K. It has the largest review file on its own ASIN, a stated fire time, a two-year warranty, and a lock line that matches the title, at £42.00 with 4.4 from 1,548 reviews. The chamber still fights a flat A4 sheet, and the box is not water resistant. The best value is the Favor S3 E at £57.99, with 4.3 from 832 reviews that belong to this listing. It is the electronic cupboard box you can name. The cheaper Favor S3 K is not the value pick, because the title and the lock field disagree. The £80.50 Favor S5 K buys litres, not a separate review sample and not a printed EN grade.
