Installing a wall-mounted letter box or external post box is a safe and secure way to keep your mail and parcels protected from the elements, but importantly, away from the kids' hands and the dog's mouth! It can also be a smart switch over from a door-mounted letter plate as it will keep heating costs down by eliminating a source of draft throughout your home.

Including options with personalised printing, viewing windows and newspaper slots, and all with a clear emphasis on rust resistance, we'll help you keep your post safe, secure and dry for many years to come.

Stainless steel is the Don of weather resistance. This is due to its element compounds of chromium and nickel, which harden the steel and make it extremely anti-corrosive. The chromium oxidizes naturally upon contact with the environment, and then forms a protective layer of chromium oxide, creating a rust-proof shield of sorts. However, this does mean it is generally the most expensive.
Galvanised steel is steel that's been given a protective layer of zinc, generally by being dipped in a molten bath of the stuff. This layer of zinc is what gives galvanised steel its weatherproofing properties, as the zinc protects the iron in the steel from reacting with oxygen. Being cheaper than stainless steel to produce, it is the most widespread form of steel for wall-mounting letter boxes, though not quite as strong.
The final material to consider for your wall-mounted letter box is aluminium. It is known to be completely rust-proof as it has almost no iron in it, which as we know, is the compound that oxidizes in other metals to form rust. It is also lightweight, strong and can be 'cast' into many different moulds and shapes, so it's a great pick if you're looking for something decorative.
Powder coating is another effective method used to protect steel from rust. It is made up of a variety of different compounds, but it's the zinc that helps to repel the rust. Powder coating is applied as a dry powdered paint, which gives an appealing finish and lasts longer than liquid paint. It is the cheaper alternative making it a good option if you're on a budget but still want a good-looking letter box.
Companies have become very savvy when it comes to fitting more post into letterboxes. Some have a built-in newspaper slot for people who still adore print, while others come with extra depth to enable multiple letters. There are also those which are, simply put, 'built big' to cater for larger families who need more space for all sorts of letters and parcels.
Another key measurement to keep in mind is the size of the mail slot as this will determine how large a letter or parcel will be able to slip through, whilst still keeping it safe from thieves and the elements. For reference, a sheet of A4 paper has a width of 21 cm and a length of 29.7 cm, so if the slot is any narrower it might only be able to accommodate regular-sized envelopes.
It's a simple design feature, but a very useful one – a letter box with a small transparent glass or plastic viewing window will allow a quick and easy glimpse inside the container, putting an end to forever finding and fiddling around with your keys, only to open the box and realise in vain that it's empty. This handy design aspect tends to come with more modern letter boxes.
Some of the market-leading wall-mounting letter box companies have incorporated a marvellous idea to have your home address printed on the front before posting it out. This will help to ensure the postperson knows exactly where to put your letters, and can also help guests to find your house more easily.
If you're someone who loves the look of vintage and historical pieces in your home, then a decorative letter box could be for you. As mentioned, these colourful and purposeful letterboxes are usually made from cast aluminium, and come in an array of antique-looking and often quite striking designs.
The most popular styles are usually those which imitate Royal Mail post boxes or even post boxes from the Victorian era. They may not have all the mod cons of some of the more contemporary letterboxes, but they're sure to look the part if you're someone who likes to revel in the prestige of the past.

Further practicalities include a matte finish of Dublin black, and with a heavy-duty galvanised steel construction, you know it's going to stand the test of weather and time. The only downside to this box is the slightly smaller postal slot, meaning it's not the best for those often getting magazine deliveries.
This is an extremely well-made letter box by the iconic lock and safety brand Burg Wächter of Germany. Its elegant and sophisticated contemporary style is only outdone by how well made it is. From the stainless steel construction to the Burg Wächter lock and key, it's certainly one to impress.
It also has a secure weather flap to keep out the rain and viewing windows to ensure you don't waste any time searching for mail that isn't there. To top it off, this box is large enough to fit A4-sized mail and has a large, well-protected letter slot.
Songmics have included many modern features in the design of this letter box. It is built from powder-coated steel to protect from corrosion and includes a copper core lock barrel and protective cap for more rust-prevention. There's also a newspaper slot, ample viewing windows and a nameplate in the top corner of the pulldown door.
A very invested letter box that has everyone singing its praises, this option looks the part, stays secure, and includes all the trimmings. For just over £20, this is a serious contender for anyone on a budget who still wants the latest in-built luxuries.
This letter box is made using high quality stainless steel, with the European manufacturer The House Nameplate Company priding themselves on it not rusting one bit! It has large dimensions and a large letter slot that's protected by a secure weather flap and would suit a family home perfectly.
The personalisation includes your home number and address in high-grade external vinyl, which comes in a number of fonts and styles. This is a uniquely stylish, remarkably well-made letter box for people who aren't on a budget.
This modern-style letter box from Secinbo kind of has it all. For starters, the galvanised steel gives it good rust-protection, and the well-made weather flap ensures no water will soak through to any important letters or documents.
Additionally, it comes with a nameplate and viewing windows so you know whether to grab your mail or not, which is always a nice touch. It even benefits from an external newspaper or magazine slot. All of these features blend really nicely with the modernistic sense of the letter box.
Available in several attractive colours, this is the classic design by Sterling that tops the best selling list on Amazon. It is very weather-resistant with an outward-opening flap and a slim letter slot to keep water and potential thieves from getting in.
This box also benefits from a stylish embossed design and has a nameplate which is always handy if you're in a block of flats. It also comes with all the wall mounting fixtures and two keys as standard. This is a quality, reliable letter box, but being on the more affordable on the market it isn't quite as sturdy as others.
Get Goods have created a work of art with this letter box. Its simple, strong and impressive cast aluminium design sets it apart from the rest with elegance and distinction by the bucket load. The man riding the horse brings on a sense of yesteryear, back when mail was potentially delivered by horseback.
It is large and heavy, so it will certainly stand the test of time with its rust-proof aluminium construction. This is a remarkable letter box and the price reflects that, so while it is a perfect choice if you're out to impress, it's definitely not one for those on a budget.
Argos have created a great option for the whole family with this letter box, as it's large enough to fit A4 sized mail comfortably thanks to the inclusion of a letter slot the entire length of the box.
This letter box will become an inconspicuous part of your home with its modern, sleek design. A powder-coating of epoxy will also stem off corrosion, ensuring the carbon steel construction protection from the elements. Though another no-frills option feature-wise, it does come with the all wall-mounting fixtures, and is certainly well-priced.
This simple and smart offering from Maison and White comes very highly recommended on Amazon from shoppers not interested in spending too much. Its galvanised steel construction gives it a good and fighting chance against corrosion, and it has a clever over-hanging lid to make certain no rain will get inside.
However, the box only has a fairly narrow top-opening slot for you to retrieve your post from, which some buyers report can be a little awkward. It's also too small for magazines. All things considered, though, you would be hard-pressed to find a better letterbox for the price!
This cast aluminium letter box from Relaxdays has an ornate English antique pattern that really transpires a sense of classic style and elegance. It is also large enough to fit A4-sized post, and comes with a secure weather flap on its slot to ensure there's no chance of any rain soaking your mail.
The strong cast aluminium construction also guarantees against any potential corrosion through rust or potential thieves breaking in. Unfortunately, the only hitch is that it doesn't come with the mounting fixtures so you'll have to find your own screws for this one.
