The letterbox is the biggest unsealed hole in most front doors. Here's why that matters to you.
An add-on to every letterplate you sell, in finishes that match your door furniture.
A counter sale for anyone fitting or refurbishing a front door.
An easy extra on the quote, and one less "my new door is draughty" callback.
A draught-proofing measure for the letterbox, fitted with a screwdriver.
The Magflap started on one of our own rentals. It fixes a winter complaint without a new door.
A low-cost measure an operative can fit on any repair visit. We've supplied a council before.
What your customers notice in the first winter.

A family business, not a call centre.
Louis and his father Nick made the first Magflap while improving the energy efficiency of a rental property. The letterbox let the cold in and nothing on the market was good enough, so they engineered their own.
Fifteen years on, the Magflap is in its third generation and every one is still hand-assembled in Leicester. When you email us, Louis or Nick will reply.
Anything else, email info@magman.uk.
The MK3 Horizontal fits standard UK horizontal letterboxes with a 70mm aperture. The MK3 Vertical fits 220 × 65mm portrait letterboxes on doors 35–70mm thick. If there are bolts or an uneven surface behind the letterbox, the optional rear gasket gives 28mm of clearance instead of 10mm. Send us a photo if you're unsure.
About 10 minutes for an MK3 with a screwdriver, inside or outside the door. The Mini Magflap sticks on in under 2 minutes.

Without. We add VAT at 20% to trade invoices.
Some of our trade customers have independently tested Magflap products for compliance with fire regulations and confirmed they passed, including for installation in large residential blocks. Magflap does not currently hold formal fire-safety accreditation or certification, and we make no fire-safety claims about our products. Where compliance has been confirmed, it was through testing arranged independently by the customer. If fire performance matters for your project, arrange your own testing and satisfy yourself that the product meets the requirements for your application.
Every product has a 1-year manufacturer's guarantee, and we can refurbish MK3 units after that.
Yes. Tell us the number of doors and the letterbox types, and we'll quote for the whole job.
