Letterboxes

Replacing the letter box on a uPVC or composite door is one of the easiest upgrades you can make. Browse our full range of door letterboxes below, from standard uPVC letterplates to fire-rated (intumescent) models for flat and communal entrance doors. Measure your aperture and door thickness first, the section below shows you how, or get in touch, and we'll confirm the right size. Free delivery is available on orders over £75.

How to measure for a replacement letterbox

To order the right letterbox, you need two measurements. First, the aperture; the height and width of the routed hole in the door. Second, the door thickness, since letterboxes are made to suit different depths (commonly 20–40mm or 40–80mm).

For a flat or communal entrance door, choose a fire-rated (intumescent) letterplate. If you're refreshing the rest of the door at the same time, our door furniture and door knockers ranges match popular letterbox finishes. Not sure on size? Send a photo on 01623 622205, and we'll match it.
