Please be aware that you can't post parcels using the post boxes, and that anything you do post may be inspected by HM Customs.
Postal services at security – Mail&Fly
Post the things you can’t take through Security with Mail&Fly's unique service. This applies to liquids over 100ml, such as bottles of wine and perfumes as well as sharp items, such as knives.
Simply pop your item in a Mail&Fly bag, peel off the numbered ticket and drop the bag in the dedicated box. Keep the ticket to reclaim your item at mailandfly.com.
The fee is £6 plus postage and packing* but you only pay if you want to reclaim your goods. You have six weeks to make your claim and items will be with you in about three days. The Mail&Fly Service at Heathrow is operated by the bagport Group
*Postage and packing costs depend on the size, weight and destination of your item.
