I found my purchase to be of the standard and quality that I had expected. Installing was easy and everyday use is simple. The storage capacity is quite generous and copes very well with our day to day post, even when we have been away for a couple of days and not emptied it. It looks rather smart in our front porch and complements the black door furniture that we have installed. Overall, I am very pleased with my purchase and would certainly recommend it to anyone who is thinking of buying this or a something product. Great value for money!!

Well, firstly the item arrived extremly well packed and very quickly.

I choose Brabantia because from past purchases of clothes line and kitchen bin l know they are very well made. Brabantia are not the cheapest products around but l believe you only get what you pay for.

I wanted a letter box that was not only nice looking but long lasting and well built.

This item fits the bill.

The item was very easy to fit to the wall, and the instructions very clear.

It is completely water tight, and just the right size.

I am very pleased with my purchase.

I would also highly recommend this item

I love this postbox, but my postman loves it more! He says it's the best on his round! My neighbours are so impressed that they have ordered six for themselves. What a recommendation.

We have been using our new postbox for some weeks now and are very pleased with it. Installing it was a bit of a fiddle - it might be best to make a template of the position of the holes before drilling - they need to be accurately placed. The screws have a supplied tool for tightening, because you are unable to access all of them with a screwdriver. The result is a secure mount that would be difficult to remove once the box is closed. The box is large enough to take A4 post and small packets and papers with ease. Access to the post would be very difficult without opening the door with the key. The structure is sturdy and weatherproof, and looks to be built to last. An excellent well thought out product.

We liked the style, colour and shape of the product, which fitted perfectly into the space available. There were cheaper boxes available - but this is solid and will hopefully last for many years. The design is classic and, to date, the deep capacity has been able to cope with several days of mail (should that be required). Ours is placed inside an open porch so it stays dry but the top is slanted which protects it against heavier, more invasive rain. Fitting it was easy, although we purchased longer screws to cope with our stone frontage. Overall, a good buy!

This was well managed by Safe from start to finish. It was easy to identify and order a suitable product. It was delivered on time. The post box itself was very easy to put up on the house wall. The build quality of the post box was very good. Since putting it up there have been no problems with post deliveries and the box copes with everything from standard letters to A4 post and small parcels. I would heartily recommend both Safe and the product.

This was not the first box we bought. The first box (another make) was very poor quality. So we purchased this new box. From the first glance we could see it was of much better quality!! Very strong and s big advantage is the the opening is on the front and closed automatically every time. Large capacity and overall s great purchase. We would only recommend this item. Simply the BEST!!!!

Having had a metal wall mounted letter box for several years we finally needed to replace it as our old box leaked, was a little small and the opening was not really big enough to take packets and small parcels. This new Decayeux D100 is ideal for our needs. Bigger volume, wider opening, fully waterproof but still looks stylish.

This mailbox was bought as a safe and secure delivery system for our repeat medication just before we went into COVID-19 lockdown. By leaving the key in the lock, the postman can open the box, pop the parcel inside and then relics the box, finally putting the key through the letter box. The order was actioned promptly and as soon as the mail box arrived it was up on the wall by the front door. Simple to fit and has performed perfectly ever since. It’s weatherproof, robust and well made and should last for years. I highly recommend this item as a pandemic precaution.

    This post box could be mounted on a post. It may require some customisation in terms of the position of the fixing holes.

    Standard Post Box Installation

    We offer professional installation on our complete range of Post Boxes.

    Our experienced engineer will complete a brief site inspection and then discuss their findings with you to agree positioning of your post box.

    Your installation will include fixing the post box to an exterior wall using the fixings included with your post box. The fixings are designed for use with a solid surface such as brick or concrete.

    The position of your post box will be governed by safe site access, and other obstructions such as submerged pipes or cables within the wall.

    The engineer will carry out a final assessment to ensure the post box is secure.

    Non-standard Installation

    In some cases, it may be necessary to install additional materials or provide extra resources (manpower) to facilitate an installation in a safe manner.

    If additional costs are likely these will be discussed with you prior to installation. Reasons for extra costs might include:

    • Specialised access equipment and permits such as hoists, lifts and cranes.
    • Outside of normal hours working (Mon-Fri, 9am to 5pm).
    • 4x4 Vehicular access requirements to remote rural sites.
    • Road closure including necessary permits.
    • Additional manpower to overcome technical, lifting or safety access issues.

    We offer installation throughout the UK mainland, however some more remote and rural post codes in the Highlands are subject to a surcharge to cover additional fuel and traveling time costs.

    The following areas will incur a rural travel surcharge:

    £55.00 Surcharge Areas

    • PH 1 - 26 (No coverage in other PH postcodes)
    • PA 1 - 19 (No coverage in other PA postcodes)
    • KA 19, 26
    • ML 11, 12

    £105.00 Surcharge Areas

    • AB
    • DD
    • TD
    • DG
    • KW

    These additional elements are deemed to fall outside the definition of a 'Standard Installation'. If you feel your installation might be non-standard please contact us to discuss your individual requirements.

    If applicable, additional costs are to be paid before installation begins.

    Warranty Terms & Conditions

    Our installer provides a standard 12 month warranty on all new installations and a 3 month warranty on all materials provided during maintenance visits.

    Note: Existing system components and pre-supplied equipment are not included in the installation warranty as these elements are covered by the Manufacturer warranty.

    We reserve the right to undertake an ‘Assessment Call’ without prejudice to investigate any complaints relating to materials failure or poor workmanship to assess if the complaint is valid. Please note that remedial service calls generated by elements outside of our sphere of influence or due to different fault conditions will be chargeable to you at an agreed call out charge.

    In scenarios where you request a post installation service call and our assessment identifies the fault condition or cause of the fault falls outside of the limitations of the standard installation warranty (Force Majeure, different fault etc) a call out charge will be incurred for the visit.

    Assessment calls raised for reasons outside our sphere of influence or responsibility and not covered by the standard installation will incur a call out charge for labour and additional materials.

    The following are examples of when a call out charge would be incurred:

    • Accidental Damage
    • Malicious Damage
    • Materials or Manufacturer Failure
    • System Modification
    • Incorrect User Diagnosis
