FAQ

What's the difference between a 'post box' and a 'letterbox'?

Essentially, they mean the same thing! ‘Post box’ is simply an older term for a letterbox – it’s where your mail gets delivered.

Why do letterboxes come in different shapes and sizes?

This largely depends on the style of your house. Round post boxes are traditional, while rectangular ones suit more modern designs; consider what will look best alongside your property.

What does ‘projection’ refer to when buying a letterbox?

Projection describes how far the letterbox sticks out from your wall. A higher projection means it's further away and likely easier to see, particularly if you have a narrow doorway.

I’m unsure about the material of a letterbox – what should I consider?

Materials like cast iron are durable but heavier than aluminium or plastic. Think about how much maintenance you’re willing to do and the weather conditions in your area.

What is ‘backplate’ and why does it matter?

The backplate is the part of the letterbox that attaches to your wall – it needs to be strong enough to support the whole unit. Ensure it's compatible with your wall type (brick, plasterboard etc.)

Can I install a letterbox myself?

Many people can install a standard letterbox themselves using basic tools like a screwdriver. However, if you're unsure about electrical wiring or working at heights, it’s best to hire a professional.

What are house numbers and why are they important?

House numbers clearly identify your property for mail delivery services and emergency services, ensuring accurate location identification is vital.

Are there different types of mounting systems for house numbers?

Yes, you’ll find options like adhesive backing, brick fixings, and wall-mounted plates. Choose the method that best suits your property's construction and preferred aesthetic.

Do I need to consider the height of my house numbers?

Ideally, house numbers should be at least 120mm high for good visibility, but check local regulations as some areas have specific requirements.

What happens if a letterbox or house number is damaged?

Refer to the manufacturer's warranty details for information on repairs or replacements. Amazon’s standard returns policy applies – you can initiate a return if it doesn’t meet your expectations.

In depth

Letterboxes and house numbers – they seem simple enough, but for someone new to buying a property, understanding what’s important and what you can safely ignore until later is key. Let's break down the basics of getting these sorted, focusing on what truly matters when you’re first starting out.

Firstly, let’s talk about letterboxes. Most new-build properties will have a standard, modern letterbox already fitted as part of the exterior wall. You’ll see these made from various materials – often plastic or sometimes metal – and they're designed to simply allow your mail to be collected by the postman. The size and shape can vary slightly, but don't worry about getting one that's perfectly bespoke at this stage. Most standard letterboxes will fit neatly into place; you’ll likely just need a screwdriver to secure it to the wall. It’s worth checking there’s enough space around the opening for the postman to easily access it – generally, 60cm wide is a good minimum size, but always check your property's specific dimensions.

Now, let’s move on to house numbers. These are absolutely crucial because they allow postal services and neighbours to identify your home accurately. Your local council or planning authority will dictate the style and size of house numbers required for your area – this is often linked to building regulations. You’ll typically find a choice of styles available, from simple black numbers on a white post to more decorative options with coloured posts and illuminated digits. The size will be determined by the distance from which people are likely to see them; larger numbers are needed further away. Again, the council or planning department will specify the exact size requirements for your property, so it’s essential to check this before purchasing anything.

Don't feel pressured to buy a particularly elaborate or expensive set of house numbers just yet. A basic, clearly visible set that complies with local regulations is perfectly adequate for a first-time buyer. You can always upgrade later if you wish. It's more important to ensure the numbers are easily readable and positioned correctly – usually mounted on a post fixed securely to the ground.

What about different types of letterboxes and house numbers? While there’s a huge range available, it's best to stick with standard sizes and styles initially. You might see options with integrated mail slots for your letterbox or decorative designs for your house numbers – these are entirely optional. Focus on functionality and visibility first.

It’s also worth noting that some older properties may require specific types of letterboxes or house numbers due to historical building regulations. Again, checking with your local council or planning department is vital before making any purchases. They can advise you on the correct style and size for your property's age and construction.

Finally, don’t get bogged down in details like different finishes (e.g., brushed steel versus polished chrome) or complex installation methods at this stage. Focus on getting a functional letterbox and clearly visible house numbers installed correctly. You can always revisit these aspects once you have a better understanding of your property and your needs. It's perfectly acceptable to start with the basics and upgrade as required – it’s far more important that they are properly positioned and easily read.
