What is an Internal Letter Plate Cover?

An internal letter plate cover is a hinged flap fitted to the inside face of your door, directly behind the letter plate aperture. It’s designed to create a cleaner internal finish by covering the inner opening, concealing screws/bolts, and improving comfort by limiting draughts coming through the letterbox.

Why Choose Polished Chrome?

Polished chrome is a popular choice for modern interiors because it looks bright, clean, and pairs easily with other chrome door hardware. If you’re matching to chrome handles, hinges, escutcheons, or door furniture, a chrome inner letterbox cover keeps the whole door set looking consistent and premium.

Key Benefits: Tidy Finish, Comfort & Simple Upgrades

• Neater interior look – covers the letterbox opening and helps disguise fixings.
• Helps reduce draughts – works like an internal flap/draught barrier behind the letter plate.
• Easy to fit – many options suit standard UK letter plate sizes and common door thicknesses.
• Great for refresh projects – ideal when updating a door without replacing the external letter plate.

Choosing the Right Size

To get the best fit, measure the internal aperture (the opening on the inside of the door) and check the fixing centres if your current cover is screwed in place. If you’re unsure, choosing a slightly larger cover can help fully conceal the opening and improve the finished look.

Best Uses: Front Doors, Porches & Draughty Hallways

A letterbox inner flap is especially useful on front doors that open into a hallway, porch, or entrance lobby where cold air can be noticeable. It’s also a great finishing touch for refurbishment work in homes, rentals, and light commercial properties where a tidy interior presentation matters.
