What is an internal letter plate cover (letterbox tidy)?

An internal letter plate cover fits on the inside of the door behind the letterbox opening. It’s often called a letterbox tidy or internal letter flap, and it helps improve privacy while reducing draughts and noise.

Do letterbox covers help stop draughts?

Yes. Internal letterbox covers can help reduce cold air entering through the letterbox opening. Many designs close the opening more effectively and some include brush seals for improved insulation.

How do I choose the right polished chrome letter plate size?

Measure the existing door cut-out and fixing centres before ordering. Choosing a letter plate with matching dimensions helps ensure a neat replacement without exposed marks or additional door work.

What doors are polished chrome letter plates suitable for?

Polished chrome letter plates are commonly fitted to timber, composite, and many uPVC doors. Always check product sizing and compatibility, especially door thickness and internal sleeve requirements.

Should I match my letter plate to my front door handles?

Matching finishes usually creates a more consistent look. Polished chrome letter plates pair well with polished chrome door handles, knockers, and other front door furniture for a coordinated entrance.

Polished chrome letter plates: durable, bright, and easy to match

Polished chrome is popular because it offers a crisp, reflective finish that pairs well with chrome door handles, escutcheons, knockers, and other front door furniture. Many designs are chosen for their balance of looks and function — including gravity flap and sprung flap styles, plus sleeved options to suit different door thicknesses. Browse the full range of polished chrome letter plates to find the right size and flap type.

Internal covers: reduce draughts and improve privacy

Adding an internal cover can make a noticeable difference, especially on exposed doors or hallways. An internal flap helps block cold air, reduces noise, and improves privacy by closing off the letterbox opening. Options may include brush seals, spring-loaded closures, or tidy-style covers depending on the product. For a matching interior finish, see our polished chrome internal letter plate covers.

Choosing the right size and fit

For the best results, measure your existing cut-out and fixing centres before ordering. If you’re replacing like-for-like, matching dimensions helps avoid visible marks or unnecessary door work. If you’re upgrading from an older letter plate, consider pairing the external plate with a coordinated internal cover for a cleaner finish inside and out.
