By Chris Cottam ,

Having had numerous off the shelf letterbox banks for a block of apartments fail due to weak metal and rusting we decided to invest in better quality units. We choose the Safety Letterbox Ltd company and their boxes far exceeded our expectations. They advised on the best solution, produced free technical specification drawings and delivered right on schedule. The letterboxes are far superior in quality of metal and construction to anything we have used previously. The price was surprisingly competitive and I would have no hesitation in recommending and using the company again.

I have been meaning to drop you a few lines about the great service we have received from Safety Letter Box Company. From the first initial enquiry when we decided to install 280 secure letter boxes in our halls of residence, Safety Letter Box Company were able to advise us what options were available in the space we had. I was impressed that the installation team sent someone to visit the site prior to the installation to assess where they were to install the boxes. An excellent job!
